Abstract Insufficient recycling of a continuously increasing amount of liquid crystal display (LCD) waste leads to the waste of potentially recyclable materials, especially rare and critical indium. Moreover, landfilling of LCD waste increases the potential for environmental risk. This paper describes a recycling process combining membrane filtration unit processes to hydrometallurgical indium recovery process. The LCD panels were crushed and leached with 1 M H2SO4. 97.4% yields on average were obtained, and a novel finding was made about fast kinetics (2 min for the maximum indium yield). Ultrafiltration was used to remove the dissolved organic material from the leachate, which was concentrated with nanofiltration before liquid–liquid extraction for indium purification. The results showed that commercial polymeric membranes removed more than 90% (from over 3000 mg/L to under 200 mg/L) of the dissolved organic compounds, thus potentially significantly diminishing the detriments caused by these compounds in the liquid–liquid extraction step. The concentration of the leachate with nanofiltration enables the use of smaller processing equipment and to save chemicals in the further steps of the process. The indium content in the leachate was more than five times higher after nanofiltration than after leaching (126 mg/L vs. 677 mg/L). In liquid–liquid extraction, the phase separation took place in only 34 s with the membrane-treated leachate, while with the untreated leachate it remained incomplete even after three hours. The purity of indium was increased from 10 to 74%. From the obtained HCl solution, a 95.5% pure indium product with 69.3% yield was obtained by cementation. Graphical Abstract

Full textAbstract:
In the laser marking process system, a liquid crystal display (LCD) was used as the image mask, which can display dynamically and flexibly the various images by the programmable control. A nanosecond pulsed laser (1064nm) was applied to investigate the characteristic of laser photolithography fabrication technology. The light modulation function of LCD mask was firstly discussed by theory. By observing the graphics morphology with a high-powered optical microscope, it was found that the graphics of laser marking with LCD mask shows that its edges were not ablated but its line inside was ablated. According to analysis, the reasons of this phenomenon are due to the opaque lattice effect and the high light transmittance of black pixel. Results showed that the light modulation function of LCD mask was decided by adjusting the light transmittance with controlling the pixel voltage and a complete graphics was ablated in the range of 0.6J/cm2 ~ 0.8J/cm2.

An immersive multiscreen display (a UT-Cave) may be assembled from common home/office equipment which can be borrowed in most research settings. The simplest design requires two LCD projectors, three personal computers, the corner of a room, a network hub and cables. The required software is an inexpensive but graphically powerful computer game, Unreal Tournament (UT), and a freeware patch called “CaveUT.” Unreal Tournament is partially open source and supports rapid authoring of visually rich virtual worlds, complex animations, and software modifications such as alternative physics or artificial intelligence. PC-based game hardware and game engines such as the one for UT deliver superior real-time graphics at a tiny fraction of the cost for traditional immersive multiscreen displays, such as the CAVE™. While currently having fewer features, the UT-Cave, like the traditional CAVE-like displays, is useful for research in vehicle simulation, human balance, architectural simulation, novel human-computer interfaces and much more. Except for UT's game engine, which is very inexpensive, everything about the UT-Cave is free and open-source at “ www.planetjeff.net/ut ”. UT-Caves with more screens have been assembled using the same basic design principles illustrated here. A sample experiment is presented which uses a four-screen UT-Cave controlled from the control program, “LabView.”

In the natural world, the human eye is confronted with a wide range of colors and luminances. A surface lit by moonlight might have a luminance level of around 10−3 cd/m2, while surfaces lit during a sunny day could reach values larger than 105 cd/m2. A good quality CRT (cathode ray tube) or LCD (liquid crystal display) monitor is only able to achieve a maximum luminance of around 200 to 300 cd/m2 and a contrast ratio of not more than two orders of magnitude. In this context the contrast ratio or dynamic range is defined as the ratio of the highest to the lowest luminance. We call high dynamic range (HDR) images, those images (or scenes) in which the contrast ratio is larger than what a display can reproduce. In practice, any scene that contains some sort of light source and shadows is HDR. The main problem with HDR images is that they cannot be displayed, therefore although methods to create them do exist (by taking multiple photographs at different exposure times or using computer graphics 3D software for example) it is not possible to see both bright and dark areas simultaneously. (See Figure 1.) There is data that suggests that our eyes can see detail at any given adaptation level within a contrast of 10,000:1 between the brightest and darkest regions of a scene. Therefore an ideal display should be able to reproduce this range. In this review, we present two high dynamic range displays developed by Brightside Technologies (formerly Sunnybrook Technologies) which are capable, for the first time, of linearly displaying high contrast images. These displays are of great use for both researchers in the vision/graphics/VR/medical fields as well as professionals in the VFX/gaming/architectural industry.

Power dissipation has been an inevitable problem of LCD systems for years. To ease the problem, many encoding methods have been developed, such as the methods of transition minimized differential signaling, the most popular one in use for DVI to date, chromatic encoding, and limited intraword transition. In this paper, the authors present the absolute difference and low-power encoding method for the serial transmission of LCD digital DVI display interface. In regard to the LCD digital display interface with UMC 90 nm technology, the proposed method minimizes the architectural complexity and reduces the power dissipation by about 67% and 12%, respectively, compared with the transition minimized differential signaling and limited intraword transition. In short, the proposed method is an efficient bus encoding method to largely decrease the dynamic and total power dissipation of the LCD digital display interfaces.

Full textAbstract:
This project proposes the measurement of heart rate accurately using an average of two readings of two different fingertip sensors and feeding them to a microcontroller and record simultaneously the photoplethysmographic data, using which an ECG waveform is plotted. The earlier projects on this topic used only one fingertip sensor in calculating the heart rate. This lacked accuracy and thus, even if the projects were economical, they could not be used at small hospitals in rural areas and village clinics. Also, they lacked the feature of graphical ECG plot that may be extremely useful for diagnosis by the medical experts. Our project is based on obtaining the heart rate by averaging the readings of two fingertip sensors. The average is then fed to the microcontroller after proper signal conditioning, and then displayed on a LCD screen. The graph of electrical activity of the heart is displayed on a graphical LCD. Also, it features sending of SMS to family members via GSM module in case of an abnormal condition. The novelty in this project is increased accuracy.

In this paper we investigate the possibility of using a large dot matrix LCD (Liquid Crystal Display) as the essential part of a low cost, user friendly human-device interface which is driving a microwave diathermy medical apparatus. The human-device interface uses only four buttons with multiple functionalities, an analog encoder and the said dot matrix LCD. The interface is a part of the embedded system that drives the entire unit, as a stand alone hardware and complex firmware program. This interface can handle the medical treatment parameters in an ergonomic and simple way. The human-device interface has been designed in agreement with the EN60601-1 and EN60601-1-4 requirements using “the simple to complex” writing and validation algorithm. The interface has been manufactured as prototype and tested on our own proprietary microwave hyperthermia and diathermy device and proves to be intuitive and easy to use. The human-device interface firmware is portable to other scientific apparatus as well; however, a reconfiguration of all displayed information is necessary, depending on the purpose of the served equipment. Compared with a colour graphic LCD equipped with touch screen, the interface presented here is definitely less expensive, can be implemented faster and uses less hardware resources.

Many of today's digital cameras allow the user to review the pictures they have captured on an LCD on the back of the camera. These cameras are capable of storing numerous pictures which the user may navigate through to share ideas, concepts, or memories with others. In this paper we present two graphical user interface concepts that were designed to provide navigation aids on Kodak digital cameras. A study is described which utilized prototypes to test the concepts before they were implemented into a product. This usability study allowed the designers to select optimal parameters for these navigation aids, including recommended picture sizes and the number of pictures to be displayed within a navigation aid that is based on a film strip metaphor.

This study aimed to develop a device for traceability of the goods delivery process, using radio frequency technology (RFID), which will inform the date, time and location where the goods are being delivered to the end customer. The methodology used consisted of three stages: 1) data collection through a portable collector along with RFID tags, 2) data processing by the microcontroller and 3) carrying out the consultation of the information contained in the tag through the communication between the RFID and the Arduino, whose product traceability was carried out through radio frequency sending information via GSM; while the materials used were 1 mega arduino board, 1 6m Neo GPS shield, 1 Sim 900 module, 1 RC522 RFID reader, 1 16x2 graphic LCD display and 1 keychain RFID tag. For testing the sending of date, time, product specifications and location information via SMS to the registered cell phone at the time of product delivery, operations were carried out in different locations with different dates and times and the messages were sent without fail. The results confirmed the display of the information “Data Collected Successfully” on the LCD display, after the reading of the LCD label by the collector. The proposed prototype proved to be effective, managing to control the delivery of low-cost goods through passive tag on a portable RFID reader.

The application of colors in a complex graphical user interface (GUI) can be a significant determinant of both the operational effectiveness and the customer appeal of software product. This paper reviews the process of color selection, the literature supporting selected colors, and the results of a colors verification study in the design of a GUI for a tower air traffic control system. This system includes workstations employing daylight readable, high resolution, flat panel color displays. As a result, this work also assessed the applicability of largely CRT-based literature and guidelines to LCD technology. Overall, the color scheme derived from the available literature was found to be both high in usability and customer appeal; the CRT-based body of literature was found to be largely applicable to LCD technology, with only minor color modifications required to selected colors.

AbstractThis study user-tested different data visualizations for highly uncertain life cycle assessments (LCAs) to determine what best supported decision-making. Precise LCAs can only be performed once designs are finalized, due to the information necessary to complete them, but design changes in such late stages are costly. If designers could have environmental impact data earlier in the process, sustainable design choices could instead be built into the initial designs. We compiled LCAs for various product categories, finding the best means of visualizing the data for online and printable dissemination. Because this LCA data varied widely within each product category, it was necessary to display uncertainty and require users to acknowledge the uncertainty. Here, four different data visualizations were tested with engineering, design, and STEM students and professionals; both quantitative and qualitative analysis determined what visualizations were most favored and forced users to consider uncertainty. We hope that this research helps LCA data be more accessible to designers and engineers in the early phases of design, allowing those without the resources or ability to perform LCA to benefit from it and design more sustainably.

A portable battery powered miniature ECG monitor with built in graphic display has been developed at low cost which can be used in rural areas, for on site patient service. It involves an analogue electronics circuit and a programmable digital circuit in the form of a Microcontroller unit (MCU). The MCU sends necessary data to an LCD graphic display screen having 128 x 64 pixels and a built-in controller. The data acquisition, processing and plotting of graphs on the screen in real time are performed through a software developed using C language. The hardware was mounted in a compact box with integrated battery. Field trial and further improvement will be needed before it can be given out to users. A little modification will make it suitable for continuous ambulatory monitoring, with data stored in an SDRAM, which can later be read into a PC and analysed by a doctor.

We propose an integrated visual haptic display using translucent flexible sheet such as rubber to enable users to feel that they are seeing and pushing virtual soft objects directly. The display varies sheet compliance in the normal direction by changing bias tension applied to the sheet: tightly stretched sheet feels hard, and loose sheet feels soft. Hence a user can feel compliance of various virtual objects when pushing the sheet. This sheet is also used as a rear projection screen. When the user pushes the sheet with a finger, the position and deformation of the pushed point are measured by stereovision. Deformation of the virtual object is calculated by FEM, and the graphic image of the deformed object is generated. An LCD projector projects the image on the sheet from the back. As a result, the user sees the finger pushing the object image. A display using urethane rubber sheet is developed: it applies bias tension to the sheet by pulling 4 corners with 4 motors. Experiments confirm the developed display generates variable compliance and simulates compliance of a real soft object. Subjects feel that they are seeing and pushing a virtual soft object directly.

Environmental sanitation is very essential for healthy living. In our daily livelihood, garbage bins are usually kept without proper monitoring until they are filled to the point of overflowing onto the surroundings and spilling out, resulting in environmental pollution, which has serious health-related issues to human beings and the environment. For smart cities, garbage bins need to be monitored and controlled to ensure a healthy and clean environment. In the present technological advancement, real-time monitoring and control of waste disposal is a challenging area that needs urgent attention by the research community. The traditional approach of monitoring waste in garbage bins placed in strategic locations is a very tedious and inefficient way that consumes time, human effort, and cost, and this is also not in agreement with smart city requirements. This research paper presents the design and implementation of an internet of things (IoT) based Arduino microcontroller working with the ultrasonic sensors that detects the level of waste in the garbage bin placed in garbage locations and constantly at regular intervals display the status information as “filled”, “half-filled”, or “empty” on an LCD screen, as well as send the content level information at those intervals to a central web-server system that displays the garbage bin levels graphically. This is achieved using a microcontroller, a Wi-Fi module, and ultrasonic sensors. The programming of the Arduino Uno microcontroller was done with an Arduino IDE and embedded C programming language. The communication with the web server was done using the hypertext preprocessor PHP scripting programming language. The prototype was designed and simulated using Proteus 8.0 professional simulation software. This process helps to automate garbage bin monitoring and control. Experimental results demonstrate a promising solution to waste management and control. A number of testing runs were performed to evaluate the device workability in real situations. The measured distances from the garbage bins were transmitted to a website; this web page performs analytic and visualization and displays a bar chart showing the levels of the garbage waste, time, and location in real time for viewing. The proposed prototype is an innovative system that will help to keep the smart cities clean and tidy using ultrasonic sensors.

Polymethylmethacrylate (PMMA) material has excellent characteristics, such as being light weight, low cost, ease of machining, and optical quality, which are useful in numerous applications such as backlit LCD display panels, lens optics, and other photoelectric fields. Laser machining of polymerization material results in a superior machining quality, high accuracy, high speed, and high reproducibility, produces a small variety of products, reduces mold costs, and enables the rapid manufacture of products based on complex graphics by processing different depths and widths of the 3D structure. This paper presents the fabrication of symmetrical array microstructures on PMMA material by using a UV laser system. The PMMA material dimensions and thickness were 20 x 20 mm and 1 mm, respectively. Regarding the machining quality, the laser pulse energy, pulse repetition frequency, and fill spacing were adjusted. For the experiments, a semiconductor laser source (635 nm/5 mW/TEM00) and a beam profiler were used to measure the characteristics of a laser beam passing through the microstructures. The microstructure pitches and morphologies also affected the light uniformity. After laser machining, the surface morphology and the light transmittance were measured using a spectrophotometer.

We present a medical records system and reminders to patients of the measurement results of non-invasive blood glucose levels. Measuring blood glucose levels is vital in avoiding potential adverse health effects like diabetes. Diabetes is a chronic metabolic disorder caused by a decrease in the pancreas to produce insulin. Generally, measuring blood glucose levels using the conventional method is injure the patient's finger. Currently, the non-invasive method was famous as one of the detections of blood glucose by applying the physical properties of laser absorption. In this paper, we use the photodiode as a detector, the LED as a sensor, and a signal conditioning circuit. The results showed that non-invasive glucose monitoring has the potential to measure glucose levels with sensitivity and linearity of 3.21 mg/dL and 98%, respectively. As a result of measuring the blood glucose levels of the subject was displayed on the LCD module was designed. We designed a simple application and medical record using Blynk applications and GUI MATLAB for recording the measurement results of blood glucose level. In the future, applications that have been developed can be used by doctors for monitoring the measurement of the blood glucose level and provide information to patients by mobile applications, sending an email or message the measurement results, the decision of a disease or not, and reminds the re-measurement time.

Background & Objective: MEMS sensors are rapidly growing as a sensing technology in all spheres of science and engineering. MEMS technology is playing an important role in avionics for miniaturization of systems and MEMS based Inertial Navigation System (INS) is one of the example. The situational awareness and performance of an aerial vehicle is computed with the help of an INS. This paper describes the case study for design of MEMS based low cost rugged INS for aerial vehicles. The 9 Degrees of Freedom (DOF) that are obtained from the sensors provide an inaccurate attitude information of aerial vehicles due to presence of external accelerations and the gyroscopic drifts in MEMS sensors. In order to overcome such problems and for the precise and reliable computation of orientation information, the error characteristics of accelerometers, magnetometers and gyroscopes have been combined into a sensor fusion algorithm with ‘Kalman Filter’ to compute the accurate orientation information. The processing has been done on STM32F407VGT6 microcontroller board. An accuracy of ± 0.1 degrees is achieved for Roll and Pitch and ± 1.0 degrees for Yaw have been obtained. The experimental results have been obtained in statically (keeping the device in a static position) and dynamically (rotating the device at different angles along roll, pitch and yaw axis) at room temperature of 22°C. Methods: The design is different in a way that it has used a unique combination of trio MEMS sensors network consisting of FXOS8700CQ Accelerometer, FXAS21000 Gyroscope, FXOS8700CQ Magnetometer. Results: The attitude estimation algorithm has been implemented on the 32-bit microcontroller. The information data is processed and displayed on 88.9 mm TFT-LCD through Graphical User Interface (GUI).

Full textAbstract:
Abstract Morphological changes observed in ammonites at the Lias-Dogger (Toarcian-Aalenian) boundary are analyzed here. The study covers all known ammonites worldwide over some 2 m.y. (the last two biozones of the Toarcian: Pseudoradiosa and Aalensis and the first biozone of the Aalenian: Opalinum). Ammonite taxonomy at this boundary is still open to question, the main disagreements being over groupings at family or super-family level. The evolutionary schema developed by Tintant and Mouterde [1981] shows two main sets of Ammonitina for the time: (1) the dominant Hammatocerataceae (Graphoceratidae+Hammatoceratidae) and (2) the final representatives of the Hildocerataceae. Two conservative ammonite stocks coexisted alongside these Ammonitina: Phylloceratina and Lytoceratina. The ammonites under review are those that made the transition from the "typically Liassic stock" to the "post-Liassic stock" prefiguring all subsequent Jurassic ammonites. A morphometric procedure is used to quantify ammonite morphological disparity rather than taxonomic diversity. A set of 35 characters were considered, corresponding to the end of the phragmocone and to the body chamber. We selected 64 morphologies covering the entire range of shapes found at the subzone scale. Morphological disparity is expressed graphically by morphospaces (first factorial plane of correspondence analysis) and arithmetically by a space occupation index (sum of variances on the factor axes). The FAD and LAD of the selected species allow us to study morphospace changes at the subzone scale. The results clearly show changes occurring in the course of the seven subzones. The earliest subzone (Levesquei) has points weakly grouped around two poles (negative and positive F1 values) with an isolated point characterized by a very negative F2 value. Changes in this morphospace from the Pseudoradiosa subzone to the Lugdunensis subzone are marked by increased dispersion around the two poles. By contrast, an increasing number of morphologies have clearly negative F2 values. The Lias-Dogger boundary displays further dispersion of the two morphological poles, leading to them becoming indistinct. Continuation after the boundary shows a very similar pattern with shapes scattered and covering most of the morphospace. The morphospace changes analyzed previously were quantified by the sum of variances of the first 15 factorial axes, representing more than 90% of the information contained in the original matrix. For the Ammonoidea as a whole, the poorest coverage of the morphospace occurred in the Levesquei subzone, while the best coverage occurred in the Comptum and Bifidatum subzones. Between-times, morphological disparity increased at varying rates with no drastic changes at the Lias-Dogger boundary. A similar procedure was performed for the Ammonitina only. Indeed, the occurrence of two conservative sets (Lytoceratina and Phylloceratina) could be suspected of inducing -- at least initially -- two peculiar morphological poles and introducing a bias into the quantification. The results are similar, bringing out more clearly the increase in morphological disparity at the end of the Lias, and its stagnation thereafter. It is difficult to say why morphological disparity increased as it did. The main problem is the lack of any clearly resolved phylogeny for the ammonites under study. However, if we accept the hypothesis of Tintant and Mouterde [1981] recognizing five homogeneous clusters for ammonites of these times, it can be seen that two of them alone (Graphoceratidae first, and Hammatoceratidae later) account for the increased disparity. Within this phylogenetic assumption, it is improbable that external constraints alone, such as eustasy or physico-chemical phenomena, could have brought about the increase, for they would probably have affected all of the ammonoids, or at least the three Ammonitina groups that were initially quite similar in shape (in the Levesquei sub-zone). It is more likely then that internal factors (e.g. heterochrony) leading to two consecutives biological "explosions" (Graphoceratidae and Hammatoceratidae) were instrumental in bringing about this increased disparity. Finally, if the Lias-Dogger boundary is clearly marked by changes at any taxonomic level, our results--based on a quantification of morphological disparity and not on taxonomy--show that changes in ammonites can only be properly understood in a broader context: there was some morphological change at the Lias-Dogger boundary but it was initiated at the beginning of the Pseudoradiosa subzone. The Lias-Dogger event was thus not an unusual or major one, but more the end of a sustained event initiated two zones earlier. This period of time (final two zones of the Toarcian) witnessed progressive growth in disparity, which ceased only at the beginning of the Dogger.

AbstractThe following case study was carried out on a sample of one experimental and one control group. The participants of the experimental group watched the movie section from the standardized LATEMO-E database via virtual reality (VR) on Oculus Rift S and HTC Vive Pro devices. In the control group, the movie section was displayed on the LCD monitor. The movie section was categorized according to Ekman's and Russell's classification model of evoking an emotional state. The range of valence and arousal was determined in both observed groups. Valence and arousal were measured in each group using a Self-Assessment Manikin (SAM). The control group was captured by a camera and evaluated by Affdex software from Affectiva in order to compare valence values. The control group showed a very high correlation (0.92) between SAM and Affdex results. Having considered the Affdex results as a reference value, it can be concluded that SAM participants evaluated their emotions objectively. The results from both groups show that the movie section is supposed to evoke negative emotion. Negative emotion was perceived more intensely than its counterpart, positive emotion. Using virtual reality to evoke negative emotion (anger) has confirmed that VR triggers a significantly stronger intensity of emotion than LCD.

The project focuses on the usage of sensing and analysis with the help of relevant sensor technologies in order to record the health conditions of people. The best way to understand this is with an example. A practising doctor who is not equipped with such technology can check the patients’ health only when the patient pays a visit to the clinic. Now, with the application of the proposed technological measures, the doctor would have a complete record of the patient whether at home, office or on the road, and this would enable him to prescribe medication in a much more efficient and effective manner. Also, it is important to appreciate that on the basis of patient data recorded in the past, a prediction model could help the doctor see irregularities and predict if a patient suffers from commonly occurring ailments hence saving time in an initial diagnosis. This method for Healthcare Data Analytics using Support Vector Machine (SVM) Algorithm helps improve accuracy when it comes to checking for specific diseases or figuring out the right treatment. Furthermore, the doctor can give a more personalized view if he has access to a large chunk of the individual’s health data along with assistance from the predictions based on modelled data. The cost of treatments can be reduced tremendously if no unnecessary tests are done. The project model first involves a tri-sensor system which takes the heartbeat, pulse-rate and oxygen saturation level of the patient. The values of all these three entities is displayed on the LCD Screen in the hardware model. The values of these sensor are able to be accessed from an Android App with the help of interfacing the App with the Hardware system using Arduino based coding. The LCD screen and Android App show the sensor data and the App data respectively which can be accessed by both the doctor and the patient’s family at any point of time simply by downloading the App. The complete history of the patient’s health is recorded in the IO server Adafruit. The MQTT protocol has been used for transferring information in sensor data from hardware to Adafruit and further publishing it from server to android app. MQTT uses a publish-subscribe methodology here with Adafruit as server while the hardware and Android App act as its two clients. The information is stored in Tabular form in Adafruit as well as in Graphical format. The graph form helps to see if any sudden discrepancies in values for sensor data occur and is used to warn
