Abstract: Automatic room lights controller can be installed in which the room lights will turn on automatically upon detection of human motion and will stay tuned until the motion stops or the person has left the room. Such type of system can be implemented where we don’t require continuous light supply but only when a person is present. The common places where we can install the system are washrooms, bathrooms, office rooms, classrooms in schools and colleges, garages, etc. Also, using this controller system, we don’t need to worry about electricity as the room lights will switch off on their own when no person is present. A huge amount of energy and economy will also be saved . The main components of the Automatic Room Lights project are Arduino Uno, PIR Sensor and the Relay Module. Keywords: Arduino Uno, Lights, PIR sensor, Relay Module

Smart street light is an intelligent control of street lights to optimize the problem of power consumption of the street, late in night. Conventional street lights are being replaced by Light Emitting Diode (LED) street lighting system, which reduces the power consumption. The focus of this project is to design a system of street lights controller to provide a reduction in power consumption. The prototype was designed by using Light Dependent Resistor (LDR), Infrared sensor (IR), battery and LED. The brightness of the lamps is being controlled in this project to reduce the power consumption. The dimming of the lamps depends on the speed of object motion detected such as pedestrians, cyclists and cars. The higher speed of moving object, the greater the level of intensity. For this idea, the innovation of street lights is not quite the same as conventional street lights that are controlled by timer switch or light sensor which automatically turns light on during sunset and off during sunrise. According to the study, motion detection devices may help to save up to 40% of energy per month.

Efficiency system in using electrical energy has been designed using a PIR motion sensor, current sensor SCT-013-030, infrared LED and relay with a controller using Arduino Uno. The system is designed to turn off electronic equipment such as air conditioners, projectors and lights automatically as a solution from users forgetting to turn off electronic equipment when it is no longer in use. The experimental results show that the system has been running well, where the system can detect no movement for a predetermined time by using a PIR motion sensor. Detection of electronic equipment using sensors SCT-013-030 has been able to distinguish the state of the equipment whether it is ON or OFF based on differences in sensor output data that is read by the Arduino analog port. Sensor data when detecting the lamp when OFF is average = 1.333 while the mini projector and TV when off the average sensor data value = 1.667. The average current sensor data when detecting lights when ON = 5,333, mini projector = 8,333 and TV = 11,333. Overall the system designed has been able to turn off the equipment that is still active when the sensor does not detect any human movement during a predetermined time

Abstract: The mainstay of the project “Automatic room light controller using PIR Sensor and Ardiuno” is the importance of seismological research around the globe is very clear. Where the lights in the room will automatically turn on upon detecting a human motion and stay turned on until the person has left or there is no motion. Initially, when there is no human movement, the PIR Sensor doesn’t detect any person and its OUT pin stays LOW. As the person enters the room, the change in infrared radiation in the room is detected by the PIR Sensor. It can be used to turn ON and OFF the lighting system of the home automatically by detecting the presence of humans. This in turn will make the Arduino to turn OFF the relay (make the relay pin HIGH) and the room light will be turned off quickly as per the time delays sets in the program.

In the conventional methods of measuring radial, axial, and angular motions of a spindle concurrently, complicated reference artifacts with relative large volume, e.g., two balls linked to a cylinder, are required. A simple and small artifact is favorable from the viewpoint of accurate measurement. This paper describes a concurrent measurement of radial, axial, and angular spindle motions using concentric circle grating and phase modulation interferometers. In the measurement, concentric circle grating with fine pitch is installed on top of the spindle of interest. The grating is a reference artifact in the method. Three optical sensors are fixed over the concentric circle grating, to observe its proper positions. The optical sensor consists of a frequency modulated laser diode as a light source as well as two interferometers. One interferometer observes an interference fringe between reflected light from a fixedmirror and 0-th order diffraction light from the grating to measure the axial motion. Another interferometer observes an interference fringe between ± 2nd order diffraction lights from the grating tomeasure the radialmotion. Using three optical sensors, three axial displacements, and three radial displacements of the proper observed position of the grating can be measured. From these measured displacements, radial, axial, and angular motions of the spindle can be calculated concurrently. In this paper, a measurement instrument, a novel fringe interpolation technique using sinusoidal phase modulation, and experimental results are discussed.

Although common in developed countries such as Japan and Taiwan, the use of lamps coupled with motion sensors are still uncommon and even rare in Indonesia. Our experiment aims to show that simple installation of commercially available motion sensors can contribute to reduce the electricity bill from the increase of energy efficiency, abundance in availability of energy being the main factor in Indonesian high energy consumption habits. High electricity demand for consumption at current supply level in Indonesia led to the rising cost of electricity bills. This factor is compounded by the fact that many electric generators in Indonesia still use fossil fuels, which contributes to the high basic generation cost. UBL is one of the universities that aim to be a green campus. Our research explores the possibility of installing motion sensors to contribute to the energy efficiency. Although mostly common in developed countries, the use of motion sensors for energy efficiency is still rare, especially in Indonesia. Despite rising cost and supply shortages, Indonesian buildings are still of high energy consumption. Our experiment shows that simple installation of commercially available motion sensors can contribute to reduce the electricity bill from the increase of energy efficiency. One of the efforts to lower energy demand on the consumer side is to use the electricity efficiently, such as turning off lights in a room when it is not in use. This method can be simply done by turning the light switches for office and classrooms, but difficult to do in public spaces such as toilets and corridors. Automatic light switches experimentally installed in sample toilet rooms prove that electricity consumption from the lamps can contribute to the reduction of total weekly energy that translates into Greenhouse Gas emission reduction.

Localizing smartphones in indoor environments offers excellent opportunities for e-commence. In this paper, we propose a localization technique for smartphones in indoor environments. This technique can calculate the coordinates of a smartphone using existing illumination infrastructure with light-emitting diodes (LEDs). The system can locate smartphones without further modification of the existing LED light infrastructure. Smartphones do not have fixed position and they may move frequently anywhere in an environment. Our algorithm uses multiple (i.e., more than two) LED lights simultaneously. The smartphone gets the LED-IDs from the LED lights that are within the field of view (FOV) of the smartphone’s camera. These LED-IDs contain the coordinate information (e.g., x- and y-coordinate) of the LED lights. Concurrently, the pixel area on the image sensor (IS) of projected image changes with the relative motion between the smartphone and each LED light which allows the algorithm to calculate the distance from the smartphone to that LED. At the end of this paper, we present simulated results for predicting the next possible location of the smartphone using Kalman filter to minimize the time delay for coordinate calculation. These simulated results demonstrate that the position resolution can be maintained within 10 cm.

This paper aims to design and develop a network infrastructure for a smart campus using the Internet of Things which can be used to control different devices and to update the management with real-time data. In this proposed system, NodeMCU ESP8266 is interfaced with thermal and motion sensor for human, humidity and temperature sensor for the room and relay to control the lights and the air-conditioned. MQTT broker is used to acquire the data and control to and from NodeMCU ESP8266, Raspberry pi and LoRa, to be interfaced wirelessly with the Node-Red. Thus, the system is controlled and monitored wirelessly with the help of the developed integrated Graphical User Interface along with the Mobile application. The performance of the developed proposed system is analyzed and evaluated by testing the motion detection in the classroom, the LoRa range with the RSSI, the average time taken by the system to respond, the average time taken for the Graphical User Interface to response and update its data. Finally, the average time taken by the system and the Graphical User Interface to respond to the lights and air-conditioned control systems is less than 1 s, and for the security and parking systems is less than 2 s.

Full textAbstract:
This study evaluated the effects of public postings on energy conservation behavior at a public university, using a multiple baseline design across three settings; bathrooms break rooms, and conference rooms. The behavior of building occupants was recorded to assess the frequency at which those individuals would turn lights off upon exiting an unoccupied room. The independent variables implemented by experimenters (light-switch plate stickers and laminated signs) had little to no effects on cumulative instances of lights turned off however, the installation of motion sensor lights produced better results. Across all conditions, lights were turned off most frequently in conference rooms (65% of observations) followed by break rooms (9% of observations), and bathrooms (3% of observations).

In this thesis we propose a solution to how a system can find and track people, as well as recognizing their gestures, in a $360^\circ$ field of view using consumer grade products. We describe a system connecting multiple depth cameras in an array and have them operate as a single camera controlled by a single computer. Using a single camera providing features such as detection, tracking and recognizing gestures of people, we specifically focus on the difficulties of preserving these features in moving forward to an array of cameras. We propose a solution based on Microsoft Kinect and Kinect SDK, using linear transformation to account for a fixed camera model to combine skeleton data from an array of Kinect sensors. Furthermore, we use positional based identification to determine whether people are being tracked by another camera in the system. The contributions of this work include insight into the challenges of building this kind of system based on Kinect hardware and software intended for use on a single computer, such as performance bottlenecks, along with possible alternative solutions. In particular, we present performance measurements for a single computer running up to four sensors and show a system that can run satisfactorily with up to at least 5 sensors on today's computers. We show what requirements on hardware can be expected for such a system, as well as where there are potential limits as the number of sensors increase.Music in Motion

Notre étude répond a l'intitulé « La Dialectique ombre et lumière dans la poésie de Baudelaire et Senghor ». Elle s'attache à décrire la sémantique de ces deux métaphores de la condition humaine dans les œuvres de nos auteurs, sous l'autorité méthodologique de la stylistique de Spitzer et de la thématique richardienne. De fait, bien plus qu'un simple ornement, ombre et lumière traduisent au mieux leur pensée et décrivent la structure des œuvres. Ainsi, sont-elles une matrice génératrice d'une esthétique, d'une philosophie, et d'une religion parfois dissonante. Opportunément, le travail tente de mettre en lumière l'apport de Baudelaire dans la poésie senghorienne. Il établit que, contrairement à ce que certains critiques ont écrit, et à ce que Senghor à laisser entendre, sa poésie n'est pas influencée par celle du poète français. Ce dernier agit plutôt comme un révélateur, en lui faisant prendre conscience de la beauté de l'Afrique et de la femme noire, leur véritable point de rencontreOur study answers to the title "The Dialectic shadow and light in Baudelaire and Senghor poetry". It strives to describe semantics of these two metaphors of the human condition in the work of our authors, under the methodological authority from Spitzer stylistics and from Richardřs themathic. Ac-tually, more than a simple ornament, a shadow and a light translate at best as possible their thought and describe the structure of the work. So, they are a generative matrix of aesthetics, a philosophy, and a sometimes dissonant religion. Conveniently, the work tries to highlight Baudelaire contribution in the Senghor poetry. It establishes that, in opposition to what some critics wrote, and in what Senghor let understand, his poetry is not influenced by that of the French poet. This last one acts rather as a revelation, by making him become aware of the beauty of Africa and black woman, their real meeting point

Full textAbstract:
A walk suspended in mid-air, a fall at breakneck speed towards a fatal impact with the ground, an upside-down flip into space, the drift of an astronaut in the void… Analysing a wide range of films, this book brings to light a series of recurrent aesthetic motifs through which contemporary cinema destabilizes and then restores the spectator’s sense of equilibrium. The ‘tensive motifs’ of acrobatics, fall, impact, overturning, and drift reflect our fears and dreams, and offer imaginary forms of transcendence of the limits of our human condition, along with an awareness of their insurmountable nature. Adopting the approach of ‘Neurofilmology’—an interdisciplinary method that puts filmology, perceptual psychology, philosophy of mind, and cognitive neuroscience into dialogue—, this book implements the paradigm of embodied cognition in a new ecological epistemology of the moving-image experience.

This chapter examines the film career of British director Terence Davies. The cinema of Davies is one of contradictions—between beauty and ugliness, the real and the artificial, progression and tradition, motion and stasis. These opposites reflect a certain struggle, for the filmmaker and his characters, to make sense of a confusing and sometimes violent world. For Davies, this struggle constitutes a reckoning with his past, a highly personal account of a fractured childhood; for the viewer it has resulted in one of the richest, most idiosyncratic, and arrestingly experimental bodies of work put out by a narrative filmmaker. The chapter focuses on the distinct emotional quandaries Davies' films evoke in the viewer and proposes that their tonal and political in-betweenness is a form of cinematic queering. Through the exploration of their contradictions, these films function within seemingly recognizable generic parameters only to then explode and thus queer conventional notions of narrative cinema.

This chapter introduces two interpretations of how we know about the world. One, the standard, sensory-to-motor view, is that physical actions for sounds, lights, tastes, smells, and so on act on our sense organs to produce messages that are sent through the nervous system to the cerebral cortex, where the relevant structures of the world can be recognized and appropriate motor actions can be initiated. The other is an interactive sensorimotor view where the nervous system records our interactions with the world, abstracting our knowledge about the world from these interactions. These two opposing views have rarely been considered in terms of specific neural pathways or the messages that they carry; that is the plan for this book. Each view leads to different sets of interpretations of experiments and to different sets of research proposals. The final part of the chapter explores a well-studied and widely taught clinical condition that illustrates the confusions that can arise when the dual meaning of the driver messages to the thalamus is not recognized.

The functions of cranial nerves, conduits for sensory information to enter and motor information to exit the brain, and the common complaints arising from cranial nerve injuries are described. The modified anatomical arrangement of sensory and motor territories in the brainstem provides a framework for understanding the organization of the cranial nerve nuclei. A thorough grounding in the anatomy of cranial nerves and cranial nerve nuclei allows the student to deduce whether a given set of symptoms arises from a central or peripheral lesion. The near triad, pupillary light reflex, and Bell’s palsy are particularly emphasized. The contributions of the six extraocular muscles to controlling eye position and to potential diplopia are described along with the consequences of oculomotor, trochlear, and abducens nerve dysfunction. The potential for lesions of facial, glossopharyngeal, vagus, and hypoglossal nerves to yield dysphagia and dysarthria are outlined.

This chapter examines Ligeti’s breakthrough orchestral works Apparitions and Atmosphères. These successful compositions translate some of the ideas developed in the electronic music studio into orchestral writing, in particular, techniques for organizing rhythm and for handling sound masses to create a static surface with a sense of internal motion. In interviews Ligeti claimed to have attempted to move in this direction while still in Hungary with the unfinished pieces Víziók and Sötét és Világos. A comparison of the extant sketches for these works shows the degree to which his experiences in the electronic studio resulted in a refinement of compositional technique, nuanced textures, and original orchestration.

This chapter examines solutions to the Maxwell equations in a vacuum: monochromatic plane waves and their polarizations, plane waves, and the motion of a charge in the field of a wave (which is the principle upon which particle detection is based). A plane wave is a solution of the vacuum Maxwell equations which depends on only one of the Cartesian spatial coordinates. The monochromatic plane waves form a basis (in the sense of distributions, because they are not square-integrable) in which any solution of the vacuum Maxwell equations can be expanded. The chapter concludes by giving the conditions for the geometrical optics limit. It also establishes the connection between electromagnetic waves and the kinematic description of light discussed in Book 1.

In this literary collection, writers explore and celebrate their lives with and love for birds — detailing experiences from Alaska to Bermuda, South Dakota to Panama. The book offers tales of adventure, perseverance, and fun, whether taking us on a journey down Highway 1 to see a rare California Condor, fighting the destruction of our grasslands, or simply watching the feeder from a kitchen window. But these essays are more than just field notes. The authors reflect on love, loss, and family, engaging a broad array of emotions, from wonder to amusement. As one author writes, “Sometimes the best bird experiences are defined less by a rare sighting than by a quality of presence, some sense of overall occasion that sets in motion memories of a particular landscape, a particular light, a particular choral effect, a particular hiking partner.” Or, as the poet Elizabeth Bradfield remarks, “We resonate with certain animals, I believe, because they are a physical embodiment of an answer we are seeking. A sense of ourselves in the world that is nearly inexpressible.” This book gives us the chance to walk alongside these avid appreciators of birds and reflect on our own interactions with our winged companions.

Elaine de Kooning (1918–1989) was a noted art critic and artist, and a prime mover in the New York art world. She was a vivacious social catalyst. Her sparkling wit enlivened meetings of the Club, nights at the Cedar Tavern, and chance conversations on the street. Her droll sense of humor, generosity of spirit, and freewheeling spending were as legendary as her ever-present cigarette. An incisive writer, she pinpointed the essence of artists as diverse as Franz Kline and August Renoir, and deftly refuted pompous critical rhetoric. As a painter, she melded Abstract Expressionism with her lifelong interest in bodily movement to capture the characteristic postures of portrait sitters ranging from artist and writer friends to President John F. Kennedy. Driven to focus on a single theme for years at a stretch, she produced multiple paintings reflecting her fascination with people and animals in motion; her subjects include bullfighting, basketball, Paleolithic cave paintings, and a multi-figure sculpture in the Jardin du Luxembourg in Paris. Married to Willem de Kooning from 1943 until her death, she credited him as her greatest influence. Although the couple separated in 1957, after episodes of unfaithfulness on both sides, nearly two decades later she bought a house near his to rescue him from severe alcoholism. Rather than being overshadowed by his fame, she said, she worked “in his light.”

Charles W. Fornara’s Herodotus. An Interpretative Essay (1971) was a landmark publication in the study of Herodotus. It is well known in particular for its main thesis that the Histories should be read against the background of the Atheno-Peloponnesian Wars during which Herodotus wrote. However, it also includes penetrating discussion of other issues: the relative unity of Herodotus’ work; the relationship between Herodotus’ ethnographies and his historical narrative; and the themes and motifs that criss-cross the Histories, how ‘history became moral and Herodotus didactic’. Interpreting Herodotus brings together a team of leading Herodotean scholars to look afresh at the themes of Fornara’s Essay, in the light of the explosion of scholarship on the Histories in the intervening years. What does it mean to talk of the unity of the Histories, or Herodotus’ ‘moral’ purpose? How can we reconstruct the context in which the Histories were written and published? And in what sense might the Histories constitute a ‘warning’ for his own, or for subsequent, generations?

This chapter commences by contextualising the politics of motherhood in light of the feminist writings of Shulamith Firestone, Adrienne Rich and Julia Kristeva. The literary analysis focuses on the control of women’s bodies and societal expectations in the work of Roberts and how the critique of motherhood apparent in these narratives reflects a tendency of much second-wave feminist thought. The second section considers the writings of Simpson and how she invokes the narrative brevity of the short story to heighten the sense of spatial constraint the female protagonist’s, who are mothers, experience; but also the temporal constraints felt by those without a child, who are aware of their ageing bodies. ‘Maternal Loss’ explores the ambivalence at the heart of motherhood and feminism while questioning how understandings of the maternal contain broader meanings and significance across cultures and in the context of migration narratives. The concluding commentary engages with the topic of feminist generations and reflects on the ways in which motherhood has been explored and re-worked as a central feminist motif across various cultural moments since the 1980s.

In its simplest form, optomechanics amounts to two complementary coupling effects: mechanical motion changes the path followed by light, but light (through radiation pressure) can drive the mechanical resonator into motion as well. Optomechanics allows one to control resonator motion by laser cooling down to the quantum ground state, or to control light by using back-action in optical measurements and in quantum optics. Its main applications are optomechanical sensors to detect tiny mechanical motions and weak forces, cold damping and laser cooling, and quantum optics. The objectives of this chapter are to provide a brief account of the history of the field, together with its fundamentals. We will in particular review both classical and quantum aspects of optomechanics, together with its applications to high-sensitivity measurements and to control or cool mechanical resonators down to their ground state, with possible applications for tests of quantum theory or for quantum information.

Smart Irrigation is a major topic that has been implemented in certain regions, but the accumulation of various sensors is the key to the effective safety of crops. In the chapter, various sensors are being deployed and used in synchronization. The primary ones included in the system are the water level and moisture sensor, which works in correspondence with the water motor; the proximity (PIR) sensor, which works in accordance with the buzzer and the webcam; and finally, the light-dependent resistor (LDR), which works in relation with the artificial light. The analog data received from the sensors are transmitted to the raspberry-pi and then sent over the network using a Wi-Fi module to Ubidots, where the data will be analyzed, and necessary actions will be taken. The components to be used in the system will guarantee overall prolific, scalable, and ardent implementation.

Designers of sensory substitution devices (SSDs) typically aim to capture a wide representational scope by requiring their devices to present in the substituting modality the full range of basic energy available to the substituted modality, and then using this information to code up any further representations needed. On this view, if we could build a device that represents to touch (say) the distal distribution of light intensity—the basic form of energy to which visual receptors are normally responsive—our device could, in principle, represent everything available to vision: colour, shape, form, motion, and so on. Unfortunately, I will argue, this simple idea fails. For perceptual modalities represent ‘emergent’ features —i.e. features whose exemplification is not fixed by the representation of the distribution of basic energy. Hence, an SSD whose basic representational vocabulary is limited to the distribution of such basic energy will leave things out. None of this shows that SSDs will inevitably fail to represent what sensory modalities normally represent. It does suggest, however, that if we want them to represent what sensory modalities normally represent, we will have to do more than preserve the representation of basic energy to which the substituted modalities are sensitive.

Traditional irrigation systems do not take into consideration the conservation of water. Therefore, automating the plant watering systems to reduce water wastage and loss would be key to water conservation as a means of making use of water wisely and responsibly. In this chapter, a smart irrigation system that helps control the amount of water applied to crops is proposed and developed. The system controls the ON/OFF state of the water pumping motor based on the soil moisture sensor reading. Other sensors incorporated in the system are the water level sensor and light dependent resistor. The system leverages on the Arduino Uno microcontroller development board to collect input signals from the three sensors. The water pump operates depending on the value of the output signal received by the relay module. This technique of watering is feasible and very affordable and reduces human intervention in field watering.

This chapter argues that typical human subjects possess distinctive multisensory perceptual capacities. Empirical evidence and theoretical considerations support the claim that perceivers are differentially sensitive to novel intermodal features, such as identity, simultaneity, motion, causality, and flavor, that could not be perceived using one sense at a time nor using several senses working merely in parallel. In light of their role in grounding cognition and guiding action, such capacities belong to perception, rather than extraperceptual cognition, for the purposes of empirical and rational psychological explanation. Therefore, multisensory perceptual capacities can serve in psychological explanations that deal with subjects and their capacities, in contrast with just subpersonal processes and mechanisms. Multisensory perception targets new features in the world. The joint use of multiple senses thus extends human perceptual capacities.

Full textAbstract:
Sensory substitution devices (SSDs) are most familiar from their use with subjects who are deficient in a target modality (e.g. congenitally blind subjects), but there is no doubt that the use and potential value of SSDs extend to persons without such deficits. Recent work by Amedi and his team (in particular Levy-Tzedek et al. 2012) has begun to explore this. Their idea is that SSDs may facilitate behavioural transference (BT) across sense modalities. In this case, a motor skill learned through visual perception might be subsequently employed in response to auditory perception, using an SSD as a mediator. They infer from the existence of such BT that the learned skill is amodally represented. After a brief overview I identify ways to more fully test for BT within this experimental paradigm and argue that their conclusion about amodal representation is premature. Additionally, I argue that their preferred SSD (Eyemusic) is of limited value for the project. While my remarks are critical, my intention is to be constructive, particularly in light of the fact that Levy-Tzedek et al. (2012) is, I believe, the first output from Amedi’s lab concerning this line of research.

This study brings to light Alexander of Aphrodisias’ modification of the notion of continuity found in Aristotle’s Physics V.3. It shows that Alexander’s interpretation of the definitions of contact and contiguity is based on his assumption that continuity is equivalent to unity and therefore he interprets Physics V.3 in terms of a strong notion of continuity which holds for continuous wholes whose motion is one. It shows further that this sense is incompatible with Aristotle’s account of continuous motion but useful for explaining the beginning of change. Its possible atomistic implications are avoided because the efficacy of the cause of change, which varies from case to case, determines the actual divisions of a continuum.

Owing to the unique features of passive sensing, low cost, large detection range and wide field of view (FOV), the pyroelectric infrared (PIR) sensors are widely used for smart home applications based on motion detection, such as light control, intrusion detection. However, due to the pyroelectricity on which their sensing principles are based, PIR sensors cannot detect stationary objects, which confines their applications to advanced sensing systems, e.g. stationary occupancy sensing. To address this issue, this paper develops a novel chopped PIR (C-PIR) sensor for detecting the presence of both moving and stationary occupants, which consists of a chopper, a servo motor, a Fresnel lens, PIR sensing elements and a controller. Theoretical analysis is conducted to reveal the working principles of the proposed C-PIR sensor. A prototype of the C-PIR sensor is fabricated and experiments are conducted to find the optimal option of the chopper material, and the optimal values of the thickness, and the chopping frequency. Results show that the proposed C-PIR sensor can sense human presence no matter if the occupant is moving or not. In experiments, the preliminary prototype shows its detection range up to 4.0 m for stationary occupant sensing and 8.5 m for moving occupant sensing. Meanwhile, the C-PIR sensor maintains the same performance of the field of view as its traditional PIR sensor counterpart. Thus, the C-PIR sensor has great potential to provide accurate occupancy information for smart building energy management.

Investigations of human motor control using functional magnetic resonance imaging (fMRI) are increasingly receiving attention, with applications in fields such as motor learning and rehabilitation. In these neuroscience studies, force and position sensors are used to control haptic devices and safely interact with the human motion in an MR environment. However, conventional force sensors such as strain gauges are known to cause electromagnetic interference originating from electrical cables, transducers, and electronics. Light transmission through optical fibers is one alternative that avoids these problems. Since optical fibers do not produce electromagnetic noise, they can be used in an MR environment without electromagnetic interference. In this paper, we propose a novel design of an MRI-compatible grasping force sensor based on these principles. The sensor structure was designed to fit into an MRI scanner with its inclined double parallel mechanism, and was specifically adapted to precision grip tasks. This paper presents the sensor design and preliminary characterization in a non-MR environment.

To increase the sensitivity of a micromechanical structure to temperature (in thermal sensing) and surface stress (in biochemical sensing) change, a novel Flip-Over-Bimorph (FOB) structure has been proposed. For detecting physically induced nanoscale motion, the operation of a piston motion optomechanical sensor using the FOB design has been demonstrated. The piston motion opto-mechanical sensor has a symmetric structure such that the structural deflection is converted into a linear displacement of a reflecting surface, which is used for optical interferometry. Through the optical measurement setup using the He-Ne laser and CCD, light intensity changes for chip temperature changes are measured, and the thermo-mechanical sensitivity of the designed sensor is 180 nm/K.

Abstract Recently, smart home applications are increasing fast, including but not limited to occupancy-dependent control of lighting, heating and cooling. Passive infrared (PIR) sensors play an important role in these applications to perceive the presence and/or the motion of human. However, PIR sensors are not able to detect stationary occupants while stationary presence takes up most time of the day. And thus, the resulted false negative detection leads to uncomfortable light/temperature swings, shortened equipment’s lifespan, and/or energy waste, etc. To address this issue, our group has developed Synchronized Low-Energy Electronically-chopped PIR (SLEEPIR) sensors that integrate an electronic liquid crystal (LC) infrared shutter with an off-the-shelf PIR sensor. In this work, the infrared shutter made of polymer dispersed liquid crystal (PDLC) sandwiched by two germanium windows is proposed to periodically chop the long-wave infrared signal received by the PIR sensor so that stationary human presence can still be detected due to the electronical shuttering. A sensor module is fabricated, consisting of a wireless microcontroller, a SLEEPIR sensor and a traditional PIR sensor, with a field of view of 103° × 103°. Then, a sensor network consists of two sensor modules is developed. Three types of experiments are conducted in this paper: individual action-based, continuous activity-based, and daily routine-based. The detection logic is made by using the threshold value classification method, where the threshold values are determined from the action-based dataset and applied to the other two datasets. The results show that for activity-based dataset, the average accuracy reached 98.96%. For daily routine-based dataset, the average accuracy is 99.57%.

Sub-micron accuracy and precision in measuring unconstrained, spatial motion is pivotal in science and engineering. It imposes stringent requirements on the accuracy, reliability, and invasiveness of sensing devices (including lasers, lidar sensors, or optical scales). While the capabilities of these devices have seen dramatic improvements in the last decades, the needs for sub-micron accuracy, low-invasive sensors greatly outpace the available solutions. The root cause of measurement difficulties is a conflict between the very nature of motion (simultaneous translations and rotations relative to a chosen reference base) and the fundamental requirement of measurement accuracy known as the Abbe principle. Small and accurate Microsystems Technology based inertial sensors (accelerometer and gyroscopes) can alleviate, or at least significantly mitigate, many of the current difficulties. If contained in small Inertial Measurement Units (IMU) and equipped with a wireless signal transmission, they can be placed on or very close to the objects whose motion is to be measured. Furthermore, as long as the IMU, its fixture, and some region of this object around the fixture can be considered as rigid, coordinate transformation rules facilitate converting signals measured by IMU into translations and rotations of any point in this rigid region. Consequently, a virtual 6-DOF sensor can be created. Its dimensions are infinitesimally small, and it can be “placed” anywhere within the above rigid region. In particular, it can be placed such that it is collinear with the displacements of the cutting tool or robot’s end effector, and satisfies the Abbe principle. We present a High Accuracy, Low-Invasive Displacement Sensor (HALIDS) for application in manufacturing and in engineering design. The sensor is capable of measuring simultaneously 6-degrees-of-freedom displacements of objects. Its short term resolution is down to 0.1 nanometer and accuracy better than 1 micron. The sensor can be built small, light and wireless. Results from experimental evaluation of two prototype versions are presented.

Wireless sensor networks (WSN) have tremendous potential in many environmental and structural health monitoring applications including, gas, temperature, pressure and humidity monitoring, motion detection, and hazardous materials detection. Recent advances in CMOS-technology, IC manufacturing, and networking utilizing Bluetooth communications have brought down the total power requirements of wireless sensor nodes to as low as a few hundred microwatts. Such nodes can be used in future dense ad-hoc networks by transmitting data 1 to 10 meters away. For communication outside 10 meter ranges, data must be transmitted in a multi-hop fashion. There are significant implications to replacing large transmission distance WSN with multiple low-power, low-cost WSN. In addition, some of the relay nodes could be mounted on mobile robotic vehicles instead of being stationary, thus increasing the fault tolerance, coverage and bandwidth capacity of the network. The foremost challenge in the implementation of a dense sensor network is managing power consumption for a large number of nodes. The traditional use of batteries to power sensor nodes is simply not scalable to dense networks, and is currently the most significant barrier for many applications. Self-powering of sensor nodes can be achieved by developing a smart architecture which utilizes all the environmental resources available for generating electrical power. These resources can be structural vibrations, wind, magnetic fields, light, sound, temperature gradients and water currents. The generated electric energy is stored in the matching media selected by the microprocessor depending upon the power magnitude and output impedance. The stored electrical energy is supplied on demand to the sensors and communications devices. This paper shows the progress in our laboratory on powering stationary and mobile untethered sensors using a fusion of energy harvesting approaches. It illustrates the prototype hardware and software required for their implementation including MEMS pressure and strain sensors mounted on mobile robots or stationary, power harvesting modules, interface circuits, algorithms for interrogating the sensor, wireless data transfer and recording.

Abstract A pulley-based movable LED light apparatus is designed and implemented based on a request from the Biology Department of the Midwestern State University to provide a controllable environment for plant research. The proposed apparatus consists of a large aluminum structure with added pulleys, the movable LED light platform, a DC-motor-driven gearbox, and electronics for sensing and control. The proposed conceptual design has been fabricated, tested, and successfully implemented in the MSU greenhouse. Performance of the initial design is also demonstrated through mechanical efficiency, light intensity profile, and the ultrasonic sensor sensitivity. Finally, some propositions are introduced to improve upon the hardware, sensors, and the control logic, that could allow for a better performance and an increased overall life span of the apparatus.
