Electronic equipment made using old technology or electronic equipment in the entry-level category has not been supported by networking equipment, so for the data communication process, the microcontroller requires interfacing facilities that are in accordance with the electronic equipment used, such as a USB port. With the microcontroller that supports IoT, it allows electronic equipment to communicate over the network. An IoT microcontroller such as the ESP32 is equipped with a WiFi feature but is not equipped with a USB controller feature, while the USB Host max3421e supports the communication process using SPI, so that those two microcontrollers can be used to form an interface using the SPI bus. This interface can be applied to electronic equipment with old technology and entry level electronic equipment for wireless communication. For the needs of making an interface between the ESP32 and max3421e, a software was developed by analyzing the SPI features of the ESP32 and the USB protocol according to the USB device state diagram. The results obtained are the handshake process between systems developed with USB devices in the Low-Speed and Full-Speed categories such as printers, flashdisk, bluetooth mouse and external hard disk, and the device descriptor data of each device tested can be read properly.

The article suggests a device that extends the functionality of the measuring devices such as generators and frequency meters. So these devices can be used as part of working standards in a complex for verification and calibrating stopwatches. The device consists of an electronic commutator and a component controlled by a microcontroller, which forms the required intervals of time and provides a necessary connection from the generator output to the frequency counter input, turned on in the pulse counting mode. The control signal simultaneously arrives at the commutator and the device for automatic start/stop of stopwatches. The circuit design of the device allows minimizing the device’s influence on the overall metrological characteristics of the complex through the use of a high-speed controlled M74HC125 buffer (high-speed CMOS QUAD BUFFER (3-STATE)) as a switch. The M74HC125 buffer in this device is the only metrologically significant node; the state switching time of which in the aspect of this task can be ignored (Fig. 3). A computer and standard software, such as HyperTerminal from the Windows XP or PuTTY distribution, are used to control and communicate with the device. The device can be connected to the computer via USB. For laboratories that have these instruments in operation, this approach can help to avoid acquisitions of the additional reference equipment, which helps to reduce the maintenance and calibration costs of reference equipment.

ECG is very important for diagnosis of cardiac disorders but most ECG equipment come from developed countries with very costly procurement and maintenance. Therefore, unless the technology is developed indigenously, common people in countries like Bangladesh will not get the benefits of modern healthcare technology. With the advent of personal computers (PC) at low cost, a PC based ECG equipment is also worth developing since many people already own a PC, thereby reducing the overall cost. With this view a PC based ECG equipment was designed and developed from the basics. An attempt was made to utilize maximum components and spares available in the local market. The main unit is based on a low cost but quality instrumentation amplifier IC with high common mode rejection ratio. Active filters were designed using common operational amplifier ICs. Right leg drive circuitry to reduce 50Hz noise of mains ac was kept as an option. Analog signal switching circuitry was used to obtain 12 Lead configurations, which were programme controlled, through graphical user interface. To achieve electrical isolation between patient and the mains ac, an analogue optical isolation circuit was designed and developed. Finally the analogue signal was converted to digital data and interfaced to a personal computer through its USB port using a microcontroller. The required power is obtained by USB port 5V supply. A medical grade isolated dc to dc converter was designed to power the patient side circuitry. Proper patient safety issues were followed in the design. Calibration was performed to make the equipment as accurate as possible. Outputs from several subjects were compared with that of reliable commercial equipment and were found to be satisfactory by cardiac experts.

Considerable efforts are made to develop Point-of-Care (POC) diagnostic tests. POC devices have the potential to match or surpass conventional systems regarding time, accuracy, and cost, and they are significantly easier to operate by or close to the patient. This strongly depends on the availability of miniaturized measurement equipment able to provide a fast and sensitive response. This paper presents a low-cost, portable, miniaturized USB-powered potentiostat for electrochemical analysis, which has been designed, fabricated, characterized, and tested against three forms of high-cost commercial equipment. The portable platform has a final size of 10.5 × 5.8 × 2.5 cm, a weight of 41 g, and an approximate manufacturing cost of $85 USD. It includes three main components: the power module which generates a stable voltage and a negative supply, the front-end module that comprises a dual-supply potentiostat, and the back-end module, composed of a microcontroller unit and a LabVIEW-based graphic user interface, granting plug-and-play and easy-to-use operation on any computer. The performance of this prototype was evaluated by detecting chronoamperometrically horseradish peroxidase (HRP), the enzymatic label most widely used in electrochemical biosensors. As will be shown, the miniaturized platform detected HRP at concentrations ranging from 0.01 ng·mL−1 to 1 µg·mL−1, with results comparable to those obtained with the three commercial electrochemical systems.

Abstract In experiments with short-pulse lasers the measurement control of the energy of the laser pulse is of crucial importance. Generally it is difficult to measure the amplitude of the pulses of short-pulse lasers using electronic devices, their response time being longer than the duration of the laser pulses. The electric response of the detector is still too fast to be directly digitized therefore a peak-hold unit can be used to allow data processing for the computer. In this paper we present a device which measures the energy of UV short (fs) pulses shot-byshot, digitizes and sends the data to the PC across an USB interface. The circuit is based on an analog peak detect and hold unit and the use of fiber optical coupling between the PC and the device provides a significant improvement to eliminate potential ground loops and to reduce conductive and radiated noise as well. The full development is open source and has been made available to download from our web page (http://www.noise.inf.u-szeged.hu/Instruments/PeakHold/).

We have developed a device, the Rehapiano, for the fast and quantitative assessment of action tremor. It uses strain gauges to measure force exerted by individual fingers. This article verifies the device’s capability to measure and monitor the development of upper limb tremor. The Rehapiano uses a precision, 24-bit, analog-to-digital converter and an Arduino microcomputer to transfer raw data via a USB interface to a computer for processing, database storage, and evaluation. First, our experiments validated the device by measuring simulated tremors with known frequencies. Second, we created a measurement protocol, which we used to measure and compare healthy patients and patients with Parkinson’s disease. Finally, we evaluated the repeatability of a quantitative assessment. We verified our hypothesis that the Rehapiano is able to detect force changes, and our experimental results confirmed that our system is capable of measuring action tremor. The Rehapiano is also sensitive enough to enable the quantification of Parkinsonian tremors.

A novel approach to computer simulator development of microwave measurement equipment is presented. The main feature of the software is an interface of the simulator, which is an interactive image of the real equipment allowing to manipulate the keys and other elements of the front panel by the computer mouse. For the measurement procedure, the simulator allows to use analytical formulas or upload the data from the computer models of the microwave devices and from the real measurements in *.s2p format. Implementation of the developed simulator into the educational process provides each student with an unlimited access to the measuring equipment and gives the opportunity not only to study the characteristics of microwave devices but also to gain experience with the real equipment due to interactive computer interface that is completely identical to real front panel.

Inspection of the condition on industrial equipment becomes an urgent matter for industry. Infrared thermography inspection provides enormous benefits in preventive and predictive maintenance routines, especially for critical electrical equipment to prevent sudden damage to the equipment when the production process is underway, insofar that it impacts on the process. The result of inspection is in the form of thermal image which depicts the temperature of the electrical equipment. In general, thermal image evaluation is still analyzed manually by relying on visual reading by technicians. This would allow for errors in evaluating the image. Thus, this study used thermal images as the results of electric motor inspections, which are in hot spot and measuring point regions. Furthermore, this study aims to quantify the overheating resulted in electric motor by comparing those two regions using color entropy by Graphical User Interface (GUI) MATLAB. The study stages comprised of: zooming and object (region) cropping on color thermal image, color image histogram, calculating of color entropy (red, green, blue), and calculating of the color entropy average. The result of study on ten electric motor thermal images showed that the color entropy is higher in the measuring point region than the color entropy in the hot spot region. The average of color entropy in hot spot region were in the range of 2.9497 – 3.9578 and measuring point region were in the range of 5.1182 – 5.4489.

TCM-ISP is a comprehensive intelligent service platform that can be flexibly applied to all links of Chinese medicines industry chain, which realizes data integration and real-time transmission as well as intelligent-flexible scheduling of equipment in response to different demand. The platform took logical framework of data flow as the core and adopts the modular design in which microcontroller and sensor module are independent to obtain overall design scheme of TCM-ISP that contains the diagram of overall framework, hardware structure, and software technology. Then, on the groundwork of overall design scheme and modern science technology, TCM-ISP was successfully constructed with flexible, intelligent, and networked characteristics in which TTL-USB and TTL-RS485S were utilized to build unified interface between boards with supporting hot-plugging mode. The results of platform tests show that TCM-ISP can not only successfully realize the integration, real-time transmission, and display of data information but also well accomplish remote intelligent-flexible control of equipment and allow flexible configuration and expansion of sensors and devices according to the needs of each link in TCM’s industry chain. It is of great practical significance to the pursuit of intelligent manufacturing of Chinese medicines and the promotion of modernization of Chinese medicines industry.

Full textAbstract:
The contact performance of various mechanical parts has important influence on the static, dynamic and motion response of mechanical equipment. The characterization of rough surface topography is the basis for the study of friction, wear and contact deformation between mechanical bonding surfaces. By analyzing the various models of the characteristic parameters of mechanical interface, we provide a systematic research idea for the model of mechanical joint surface in the future. For further details on rough surface profile, the G-W model is put forward. Then the M-B model perfects its lack of scale independence. The relationship between actual contact area and load is derived from the M-B model based on fractal geometry theory. These formulas are used to study the characteristic parameters of mechanical interface, and the fractal model of contact damping and loss factor is established. Since fractal parameters are not limited by sampling length and resolution of measuring instrument, the new models are more reasonable than before. However, just as the M-B model needs to be improved, the model based on this need to be further studied, and the application of the model also needs to be explored more.

Describing body size (anthropometry) and physical properties of the body (biomechanics) are areas of interest both in research and in application. The human factors engineer needs anthropometric and biomechanical information primarily for designing the operator/equipment interface. Available information is piecemeal, incomplete, and often not compatible since researched and provided in various scientific disciplines. However, even the researcher is hindered by the “scatter” of data, measuring techniques, and research objectives. Hence, an effort to standardize in the areas of anthropometry and biomechanics would, if done properly, help both scientists and engineers.

Full textAbstract:
Construction activities often generate intensive ground-borne vibrations that may adversely affect structure safety, human comfort, and equipment functionality. Vibration monitoring systems are commonly deployed to assess the vibration impact on the surrounding environment during the construction period. However, traditional vibration monitoring systems are associated with limitations such as expensive devices, difficult installation, complex operation, etc. Few of these monitoring systems have integrated functions such as in situ data processing and remote data transmission and access. By leveraging the recent advances in information technology, an Internet of Things (IoT) sensing system has been developed to provide a promising alternative to the traditional vibration monitoring system. A microcomputer (Raspberry Pi) and a microelectromechanical systems (MEMS) accelerometer are adopted to minimize the system cost and size. A USB internet dongle is used to provide 4G communication with cloud. Time synchronization and different operation modes have been designed to achieve energy efficiency. The whole system is powered by a rechargeable solar battery, which completely avoids cabling work on construction sites. Various alarm functions, MySQL database for measurement data storage, and webpage-based user interface are built on a public cloud platform. The architecture of the IoT vibration sensing system and its working mechanism are introduced in detail. The performance of the developed IoT vibration sensing system has been successfully validated by a series of tests in the laboratory and on a selected construction site.

Methane (CH4) emission from the aquatic environment is considered as one of the sources of greenhouse gas contributes significantly important to the global warming. For measuring continuously the methane emission from the water-atmospheric interface an automatic sampling and measurement system using floating chamber integrated methane sensor (Automated Floating Chamber integrated Methane Sensor - AFCMS) has been fabricated including the control and PIC datalogger boards with a lower cost than a commercial product. The floating chamber integrated a methane sensor (Panterra, Neodym Technologies, Canada) which works well not only on the quiet water surface but even on the oscillated one. The sensor (coded 1501-1) has a low LOD = 0.45 ppm and a good linearity (R2 = 0.9947) of methane concentration ranging from 2 to 30 ppm. AFCMS system shows a good performance of the equipment deployment for sampling and measuring the methane emissed from the urban canals.

Full textAbstract:
The investigation of the neural correlates of human gait, as measured by means of non-invasive electroencephalography (EEG), is of central importance for the understanding of human gait and for novel developments in gait rehabilitation. Particularly, gait-event-related brain potentials (gERPs) may provide information about the functional role of cortical brain regions in human gait control. The purpose of this paper is to explore possible experimental and technical solutions for time-sensitive analysis of human gait ERPs during spontaneous and instructed treadmill walking. A solution (hardware/software) for synchronous recording of gait and EEG data was developed, tested and piloted. The solution consists of a custom-made USB synchronization interface, a time-synchronization module, and a data-merging module, allowing the temporal synchronization of recording devices, time-sensitive extraction of gait markers for the analysis of gERPs, and the training of artificial neural networks. In the present manuscript, the hardware and software components were tested with the following devices: A treadmill with an integrated pressure plate for gait analysis (zebris FDM-T) and an Acticap non-wireless 32-channel EEG system (Brain Products GmbH). The usability and validity of the developed solution was investigated in a pilot study (n = 3 healthy participants, n = 3 females, mean age = 22.75 years). The recorded continuous EEG data were segmented into epochs according to the detected gait markers for the analysis of gERPs. Finally, the EEG epochs were used to train a deep learning artificial neural network as classifier of gait phases. The results obtained in this pilot study, although preliminary, support the feasibility of the solution for the application of gait-related EEG analysis.

The present technical condition of the fleet of electric motors serving the actuators of the infrastructure facilities of the fuel and energy complex is presented. The statistics of damage and damage from abnormal operation of electric drive units operating on mechanisms with a fan and pump load are given. The analysis of the causes of the increase in the range of vibration displacement, which leads to premature failure of electric motors, is given. A method for reliably determining the causes of damage, based on measuring and analyzing the electrical parameters of the harmonic spectrum of the motor current, is proposed. Its essence consists in creation of the universal diagnostic system working at the physical principle at which any indignations in work of an electric and mechanical part of the engine and related actuator lead to modulation of the consumed current. Existence in a range of current of characteristic frequencies of a certain size demonstrates existence of these or those damages. The device for its implementation includes phase current sensors of the supply voltage, a signal conditioner for normalizing and filtering signals, an analog-to-digital converter with a USB interface, and a controller with software for analyzing, evaluating, and diagnosing the condition. Experimental results have been obtained confirming the adequacy of the methodology and technical means for monitoring electric motors of various mechanisms.

Full textAbstract:
Measuring friction between the tyres of a vehicle and the road, often and on as many locations on the road network as possible, can be a valuable tool for ensuring traffic safety. Rather than by using specialised equipment for sequential measurements, this can be achieved by using several low-cost measuring devices on vehicles that travel on the road network as part of their daily assignments. The presented work proves the hypothesis that a low cost measuring device can be built and can provide measurement results comparable to those obtained from expensive specialised measuring devices. As a proof of concept, two copies of a prototype device, based on the Raspberry Pi single-board computer, have been developed, built and tested. They use accelerometers to measure vehicle braking deceleration and include a global positioning receiver for obtaining the geolocation of each test. They run custom-developed data acquisition software on the Linux operating system and provide automatic measurement data transfer to a server. The operation is controlled by an intuitive user interface consisting of two illuminated physical pushbuttons. The results show that for braking tests and friction coefficient measurements the developed prototypes compare favourably to a widely used professional vehicle performance computer.

The ageing society has resulted in imbalances in the population age ratio. The ratio of working-age people was less than that of elderly people resulting in a shortage of elderly caregivers and increased healthcare costs. Although the lifestyle the elderly remains the same, their physical abilities are reduced, requiring them to rely on special equipment when traveling in order to gain more control and safety. Therefore, the Elderly Personal Mobility Device (EPMD) is developed using Internet of Things (IoT) technology to reduce the burden of caregivers, provide freedom and safety for elderly travelers, assess air pollution risks, and alert the occurrence of emergency events. The EPMD is designed in terms of structure, electrical equipment, and sensor systems. First, the shapes, sizes, and thicknesses of the carbon steel used for construction of the EPMD structure are calculated by using SolidWorks software. Next, the electric equipment is carefully selected to meet the requirements of actual use. Finally, the sensor system is designed to monitor the EPMD status and air quality using IoT devices to create a data interface and big data for elderly health service development, as well as an air quality map with distributed measuring stations and a charging station detection system for future use.

Statistical analysis of ICE system faults shows a considerable growth of gas distribution mechanism failures: on average 7-12 %.This is explained by complicacy of gas distribution elements and occurrence of numerous new elements ( hydraulic pushers, hydraulic tensioners, automatic correcting mechanism of gas distribution phases, multivalve systems). However, in practice improvement of the gas distribution mechanism conspicuously surpasses development of new veracious techniques and methods of technical condition control. Development of new techniques and methods of technical condition control over the gas distribution mechanism enables solving of the important task to increase the engine operational resource. The most informative and veracious diagnostic method is vibroacoustic one, which makes it possible to evaluate technical condition of gas distribution mechanism at any stage. In order to diagnose the gas distribution mechanism with consideration of minimum interference and maximum information content, we chose the equipment which includes USB-Avtoscope III (Postolovsky oscillograph), a laptop with data analysis software, a pressure sensor for pressure control in the cylinder and an accelerometer. For prevention of linear expansion of metals , diagnostics was made on the engine with the temperature ranging from +80 to +90° C (measurements which are taken by a measuring probe within this temperature range are identical). The maximum expansion of metal was fixed at 1100 min-1 in 14 sec., at 1300 min-1 - 13 sec., at 1500 min-1 - 10,2 sec. Change of valve expansion clearance from 0,35 mm to 0,7 mm reduces the valve opening phase by 2×15°30′ (i.e. results in considerable delay of valve opening by 15°30′ and acceleration of its closure by 15°30′).

During the operation of state district power station, it is necessary to calculate the technical and economic performance (TEP) of the equipment operation based on the results of measuring the parameters of heat carrier flows. In particular, such tasks are solved during thermal (balance, functional) tests of heat and power equipment, as well as during the preparation of monthly technical reports of the state district power station on thermal efficiency. Therefore, the urgent task is to develop the model of calculating the indicators of the thermal efficiency of the equipment of the state district power station using modern computerized tools. Methods of business processes modelling, and mathematical modeling are used to solve this problem. The developed model of the project is based on the principles and approaches of systems analysis. The model is adapted to a specific subject area and allows you to optimize the process of calculating the key parameters of the efficiency of the state district power station operation: power plant capacity, heat load, specific fuel consumption and overall efficiency of the power plant. An information system model was developed to automate the process of calculating the TEP to ensure a more economic operation of equipment due to reducing the time and cost of this process.Based on the analysis of the developed models, a project was developed to automate the process of TEP calculating to ensure more economical equipment operation, to predict equipment repair, and assess the quality of operating personnel work. The paper presents the architecture of the solution of the information system for TEP accounting, the model of the subsystem of calculation modules, the structural diagram of the operation of the data collection module, the interface of designed information system. The developed model of the project for automation of the TPE calculation process allows us to increase the efficiency of the enterprise due to increasing the efficiency and promptness of managerial decisions, reducing fuel costs, saving on consumables, and personnel cuts.
