This article describes calibration method of automatic weighing instruments for measuring vehicles in motion. These measuring instruments in future will be widely used to determine the axle loads, if applicable the axle-group and vehicle mass of road vehicles when the vehicles are weighed in motion. For several years, some activities have been carried out on the weight control system that determines the mass of vehicles moving at higher speeds, called HS-WIM. The implementation of such systems will affect both the improvement of road safety and indirectly limit the number of road users moving by overloaded vehicles.

A basic of process control is to understand process conditions with measuring instruments and to operate processes so as to realize target conditions. If input measured values were inaccurate, output of manipulated variables would become improper and, as a result, it would be difficult to bring the process to the desired condition. In the wastewater treatment process, thanks to the latest progress in sensor technology, numerous automatic measuring instruments have been introduced. However, because of adverse environmental conditions peculiar to the wastewater treatment process such as slime-contaminated sensing elements, long-term continuous measurement is rather difficult. We believe such disadvantages in the measurement are making automatic control of the process very difficult to achieve. Under such circumstances, we have developed a detection system for unusual data which automatically checks six items of deviation from upper and lower limit values, rate of change (too much or too little), collating data from similar measuring instruments, etc. based on the measuring data of the last 30 days. With this system, validity of the accumulated data is being checked using measuring data. Accordingly, it enables us to deal with characteristics of measuring instruments, situations of wastewater treatment plants, seasonal changes, etc. automatically. In this report, automatic methods to establish judgement criteria, structure of this detection system and logic of detection of unusual data are introduced. Furthermore, test results with the data collected from actual wastewater treatment plants are covered.

Abstract Monitoring systems using automated electronic total stations are an important element of safety control of many engineering objects. In order to ensure the appropriate credibility of acquired data, it is necessary that instruments (total stations in most of the cases) used for measurements meet requirements of measurement accuracy, as well as the stability of instrument axis system geometry. With regards to the above, it is expedient to conduct quality control of data acquired using electronic total stations in the context of performed measurement procedures. This paper presents results of research conducted at the Faculty of Geodesy and Cartography at Warsaw University of Technology investigating the stability of “basic” error values (collimation, zero location for V circle, inclination), for two types of automatic total stations: TDA 5005 and TCRP 1201+. Research provided also information concerning the influence of temperature changes upon the stability of investigated instrument’s optical parameters. Results are presented in graphical analytic technique. Final conclusions propose methods, which allow avoiding negative results of measuring tool-set geometry changes during conducting precise deformation monitoring measurements.

In the development of a unified multi-channel interface temperature control module for measuring instruments, built on a main-modular principle on the basis of the central instrument module and used on spacecraft for various purposes, the primary task is to determine its structure, which allows to provide temperature control on the elements of the spacecraft design in different measurement ranges and with different requirements for accuracy and stability of measurement. The article is devoted to the analysis of general requirements to the structure of the multi-channel interface temperature control module, in which the measuring channels can have different technical characteristics and the choice of variants for measuring the resistance of thermal converters to ensure the elimination of the systematic component of the measurement error. It is shown that in the structure of a unified multichannel interface temperature control module there should be a multichannel measurement scheme forming several measurement channels with different technical characteristics operating on a common channel of analog-to-digital conversion. To match the measuring channels with different input resistances and operating in different measurement ranges with the common channel of the analog-to-digital converter, it is necessary to use a controlled normalizing amplifier. To eliminate the systematic component of the measurement error, it is necessary to use three- or four-wire variants of the measurement schemes of thermal resistance converters, which allow the automatic compensation of the measurement error introduced by the resistances of the wires of the communication lines of the measuring cables, and the automatic calibration of the measurement error introduced by the measuring channels. To compensate for the nonlinear component of the measurement error introduced by thermal resistance converters, it is necessary on the basis of piecewise linear approximation of their nominal static characteristics to divide the operating ranges of measurement into subranges and to carry out automatic calibration measurement errors in each subrange separately.

The article proposes promising trends of research in the field of building automated systems for controlling the movement of transport vehicles (TS) in order to ensure a continuous monitoring and operational control. A method for substantiating technical requirements and assessing the characteristics of measuring instruments for automated control of vehicle movement, an algorithm for determining the optimal values of characteristics of measuring tools and an algorithm for choosing the optimal version of telematic automatic control devices (TASK) for vehicle movement have been developed. The concept of a telematic automated control system for controlling the movement of vehicles (TASU CD TS) is formulated. The presented results make it possible to build the TASU CD of the vehicle based on the optimal choice of TASK movement and the assessment of the effectiveness of their application. Creation of a local telematic automated control system for controlling the movement of the vehicle will effectively manage traffic flows through the implementation of continuous control and monitoring of the vehicle along the entire route of movement, and operational coordination of the interactions of all road users, special services and departments.

The introduction of an automated control system on the production line of the rubber compound will reduce the influence of the human factor on the quality of rubber products, which will lead to a significant improvement in the operational and physico-mechanical characteristics of the final product. Also, the development of this system will create a centralized data collection system for creating reports on technological operations of the production process. To obtain high-quality products, it is necessary to control and maintain all technological parameters during equipment operation at the same level, modern means of registration and parameter management. In the production of rubber compounds, it is necessary to ensure a high degree of automation of the main technological equipment, which will make it possible to more accurately dose the ingredients, including dusting ones, to conduct the process in a given temperature regime for the time required to obtain high-quality products. The implementation of automatic control during the use of high-performance equipment is not possible without the use of measuring and control equipment. The article is devoted to the problem of automation of a system for measuring technological parameters on a rubber compound production line in order to improve the quality of manufactured products. The analysis of the technological process is carried out, the controlled parameters of not only the modes of the technological process, but also of raw materials, semi-finished products and finished products are selected. The choice of instruments and local automation equipment is presented, as well as the choice of an industrial microcontroller with which control is carried out at the lower level of an integrated automation system. A functional diagram of the automation of the rubber compound production process is proposed, which will allow to obtain a product with quality indicators corresponding to the regulated level.

Abstract. The longest ozone column measurement series are based on the Dobson sun spectrophotometers developed in the 1920s by Prof. G. B. W. Dobson. These ingenious and robustly designed instruments still constitute an important part of the global network presently. However, the Dobson sun spectrophotometer requires manual operation, which has led to the discontinuation of its use at many stations, thus disrupting long-term records of observation. To overcome this problem, MeteoSwiss developed a fully automated version of the Dobson spectrophotometer. The description of the data acquisition and automated control of the instrument is presented here with some technical details. The results of different tests performed regularly to assess the instrument's good working conditions are illustrated and discussed. Compared to manual operation, automation results in a higher number of daily measurements with lower random error and additional housekeeping information to characterize the measuring conditions. The automated Dobson instrument allows for continuous observation of the ozone column with a resolution of ∼ 1 DU under clear-sky conditions.

Abstract Precision measurements of friction processes have a key role in a variety of industrial processes. The emergence of fine electronic circuit techniques greatly expands capabilities of control. There are some difficulties for their full implementation today, especially when it regards the accuracy and frequency of measurements.

We present a system of device control programs, developed for the solar observatory at Locarno/Switzerland (IRSOL). Because these programs are implemented as servers—clearly separated from the higher levels—scientific instruments, for example, telescopes, can be operated both in a user-controlled mode (GUI,telnet) and in a fully automated mode by use of a script. Astronomical instruments such as telescopes or spectrographs will be responded to by ASCII command strings, which are the same for all clients. In case a device control software does not support multiclient operation or in case it is used together with other devices in a complex measuring procedure, it is worthwhile implementing an intermediate layer that relieves the individual device control servers of routine tasks and provides for a safer operational sequence. In addition, the system may make use of an easy-to-learn script language specialised for controlling fully automated processes.

Currently, most of the techniques of dial manufacturing for electrical measuring instruments are low-productive and expensive owing to the single-piece dials’ manufacturing. Application of laser engraving system as a way to produce individual dials for the electrical measuring instruments is described in this paper. The automated system is expected to increase productivity, reduce cost, and improve the quality of the final product. A novel structure of hardware–software system was created for single-piece dials’ manufacturing and special novel software system was developed to control the system and to verify scales’ quality. Damped oscillations parameters of instrument pointer were determined. The real-time recognition algorithm of instrument scale was developed. These innovative solutions have been allowed to upgrade the instruments’ accuracy class from 2.5 to 1.5 and to reduce the time of making information marks on the dial by 13.2 times in comparison with traditional techniques. The following technological operations have been excluded: relief printing, manual calibration, and manual scale marks drawing.

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.

Recently, the screens of TVs and computers are getting larger and larger. In accordance to that, surface plates of those, which are used during the production process, are also becoming bigger. These surface plates are required to be checked every certain period of duration. Therefore, an automatic measurement of straightness, that is highly accurate, and capable of measuring large area, is necessary. The straightness is the degree of difference from a straight line geometrically. It is one of the indexes to express machining precision. In Mechanical Engineering, the accuracy of processing side and the exactitude of the table and the surface plate, which are the bases of the processing side, decide the quality of products. There are a number of methods to measure the straightness. In this experiment, we use a straightness-measuring instrument, which moves a gauge parallel to the surface, and measure the values. Fig. 1 shows the appearance of straightness- measuring instrument. This straightness-measuring instrument is consisted of guide rail, carriage, and support blocks. During the actual measurement, the control of the carriage to connect the gauge is manually operated. This manual operation is simple, but measurement time and precision greatly depend on individual skill. In addition, measuring process requires good length of time with intensity, hence it causes the worker mental exhaustion. Therefore, if we can mechanically operate the carriage it will improve the accuracy and data collection will be easier. This research is aimed to mechanically operate the straightness-measuring instrument and measure consecutive positions in a short period of time. This report explains the design, production, and motion test of the automatic movement mechanism of the carriage.

Background. Immunological and infectious safety of blood components is considered to be a key condition for high-quality transfusion therapy. The progress of blood filtration methods contributes to the development of methods for the validation of residual leukocyte control in blood products.The aim of the study was to compare the efficiency of flow cytometer with hematology analyzer for counting residual leukocytes in blood productsMethods. In this study, we compared the efficiency of two analytical instruments for counting residual leukocytes in 191 blood plasma samples: a flow cytometer (Navios Beckman Coulter) with a LeukoSure commercial reagent kit and a Sysmex XT4000i hematology analyzer.Results. All the samples under investigation met technical regulation requirements. Most of the samples were characterized by a significantly low amount of residual leukocytes, which fact presented a particular scientific interest. The use of a Navios Beckman Coulter flow cytometer and a commercial reagent kit allowed us to detect 15 or lower cells per μL in 83 % of the samples. The use of a Sysmex XT- 4000i automatic hematology analyzer for the calculation of residual white blood cells in this range proved to be limited due to the sensitivity of the device and the absence of certified reference materials with a low white blood cell count.Conclusion. Our results show that a Navios Beckman Coulter flow cytometer with a commercial reagent kit is suitable for measuring residual leukocytes in blood plasma. This instrument is most appropriate for samples with a minimum number of cells. A significant variability of the amount of residual white blood cells in blood plasma confirms the importance of inspecting the content of leukocytes in all blood components.

Abstract Biacore biosensors (Biacore AB, Uppsala, Sweden) have proven to be robust analytical tools for the automated immunochemical detection of different adulterants and contaminants in milk and milk powder. However, the significant cost of the instruments is a disincentive for their wide application in food control laboratories. Therefore, a low-cost alternative optical biosensor (Spreeta, Texas Instruments, Attleboro, MA) was built into an affordable liquid handling system. Using this prototype biosensor, an inhibition immunoassay for bovine κ-casein was evaluated for the detection of cow's milk in ewe's and goat's milk and for the detection of bovine rennet whey powder in milk powder. Comparable sensitivities were obtained for both adulterants in the Spreeta-based prototype biosensor and a Biacore 3000 instrument. The limit of detection for cow's milk was 0.17% (v/v) and bovine rennet whey powder could be detected in milk powder above 1% (w/w). The Spreeta sensor was also useful in the control of fraudulent water additions to milk, simply by measuring differences in the bulk response.

Purpose – The purpose of this paper is to present a fully automatic calibration method for hand-eye serial robot system is presented in this paper. The so-called “fully automatic” is meant to calibrate the robot body, the hand-eye relation, and the used measuring binocular system at the same time. Design/methodology/approach – The calibration is done by controlling the joints to rotate several times one by one in the reverse order (i.e. from the last one to the first one), and simultaneously take pictures of the checkerboard patterns by the stereo camera system attached on the end-effector, then the whole robot system can be calibrated automatically from these captured images. In addition, a nonlinear optimization step is used to further refine the calibration results. Findings – The proposed method is essentially based on an improved screw axis identification method, and it needs only a mirror and some paper checkerboard patterns without resorting to any additional costly measuring instrument. Originality/value – Simulations and real experiments on MOTOMAN-UP6 robot system demonstrate the feasibility and effectiveness of the proposed method.

Monitoring the geometric parameters of cutting and cleaning ballast during reconstruction and overhaul works is one of the most important tasks of ensuring high quality repair work. The paper describes a new type of automated control system to control the cutting process and the cleaning of ballast performed at major overhaul and reconstruction. This automated control system uses the data of a multisystem GNSS receiver, base Reference stations and spring-return mechanisms for installing antennas on the working body of the track machine (bar chain). Nowadays, gravel-cleaning machines have installed standard work quality control systems (depth of ballast cut and lateral slope), and other measuring control tools are also used. The disadvantages of existing technologies and instrumental testing are considered. The modern automatic control systems of various types developed by SGUPS and based on the use of global navigation systems are presented. Detailed schemes of working elements of ACS installed on the ballast cleaning machine (BCM) are presented. Algorithms to determine the depth and cross slope of the ballast cutting and control of these values are considered. The use and effectiveness of this type of ACS providing the required accuracy of work and continuous monitoring of the main quantities are substantiated.

Full textAbstract:
An automated analyser for total hydrocarbon contents and hydrocarbon composition (from methane to pentanes) was constructed and tested in both laboratory and field exploitation. It used two-channel analysis: continuous measurements of total hydrocarbon contents and periodic (90 or 150 s) composition analysis after separation of hydrocarbons on a gas chromatographic column. Flame ionization detectors were used in both channels. A simple 16-bit analogue-to-digital converter was used (4.8, practically four orders of magnitude), while the full measuring range (six orders of magnitude) was ensured by automatic dilution of the sample (or standard) with clean air. Full control of the operating (calibration/analyses) cycle was performed by microcomputer. An external programme, based on a computer provided with full information on the instrument operating conditions, presents the results of calibrations/analyses and enables them to be archived in a standard database used in the oil/gas drilling industry (N-LAB) by providing a suitable link. The instrument measuring range was 1 ppm to 100% with precision not worse than 5% at the detection limit. The analyser can operate autonomously for two months, recalibrating itself daily.

The use of standard instruments (colorimeters) when measuring the color coordinates and chromaticity of multicolored objects and having relatively large dimensions is practically impossible. This is due to the fact that ordinary colorimeters, no matter what method is implemented in them, are designed to determine the color of a specific point of the measured object. This article discusses a method for determining the color of a multicolored and relatively large object, for example, a car, color photography, art painting, etc. Let us call this method computer colorimetry. A practical solution to this method can be used in such areas of the national economy, as, for example, repainting a car after damage to certain parts ofthe body with damage to the paintwork, automatic control and video surveillance of forest and peatland areas to detect fires, intheexamination of the authenticity of documents and works of art, and other areas of the national economy.

Abstract The aim of the article is to look at the possibility of accurately determining the energy efficiency of drive systems thanks to the use of high quality sensors and measuring instruments. The types of measuring instruments used on the test stand are presented. The results of experimentally determined efficiencies and simulationally determined efficiencies of two hydrostatic systems with throttling control were compared, which are fed with a constant capacity pump. The choice of the analysed systems is not accidental. There is still a view in the literature about limited possibilities of energy systems with proportional control. The research stand was very carefully designed and made. The applied measuring instruments were characterized by high accuracy of measurements. The issues related to the determination of energy losses and energy efficiency of the engine or drive system, which should be determined as dependent on the physical quantities independent of these losses, were also discussed. For laboratory verification, measurement methods were developed, the test stand was adapted and automated. It consists of tested system and loaded system. The measurements during the tests were saved on the computer disk. In order to be able to compare the efficiency of the overall system with the efficiency obtained on the basis of the simulation, coefficients ki determining the energy losses of individual elements of the system were calculated. The research showed a large convergence of the mathematical description of energy losses in the elements of the system and the efficiency of the system with reality. The mathematical model enables accurate simulation determination of the energy efficiency of the system at each point of its field of operation, i.e. at each speed and load of the controlled hydraulic motor. The range of motor speed and load variation can also be accurately determined simulationally.

Full textAbstract:
For some years now, measuring instruments have been employed at wastewater treatment plants in Germany to continuously monitor ammonia (NH4), nitrate (NO3) and phosphate (PO4). Altogether, almost 3,000 monitoring units are currently in use at a total of approximately 600 treatment plants of all sizes. In addition to continuously monitoring the treatment plant effluent and individual treatment processes, these allow the adjustment and control of plant units and, thus, a saving in operating costs, particularly with respect to the consumption of energy and chemicals. In addition to characteristic data on the instruments, investment and operating costs play a major role when deciding to purchase measuring instruments of this type. Therefore, the German Technical Wastewater Association's (ATV) working group on the “Automation of Wastewater Treatment Plants” resolved to prepare, within the framework of the ATV rules, a code of practice on “Requirements with respect to On-line Analyzers for Nitrogen and Phosphorus Compounds” (M 269). The purpose of this is to provide planners, operators and public authorities with advice on the design and reliable operation of on-line analyzers and the appurtenant peripheral equipment. The present text describes the essential contents of M 269.

Full textAbstract:
A computer-controlled automated gas-exchange system was developed to perform repetitive measurements of physiological activities in intact plants. Shoot and root temperatures, flow rates, gas pressures, rates of leaf CO2 and H2O exchange, and rates of CO2 exchange, H2 evolution, and C2H2 reduction by the roots can be determined for four plants in a single experiment. The controlling computer operates 32 switches that control gas flows, sampling devices, lighting, and irrigation and it records and processes analog data from 15 measuring instruments. Rates of physiological activities are calculated automatically and results are printed and stored on diskettes for later plotting or analysis. A wide variety of experimental protocols are possible with little need for computer programming, because the system is controlled by a master program and an interactively developed file of experimental variables. The values recorded from the measuring instruments are proportional (r2 > 0.999) to either independent determinations or to calibration standards and the rates of physiological processes, measured with the system, are reproducible and within expected ranges.

Today many WWTPs are equipped with different on-line instruments for automatic and manual control of the process. The use of computerised systems for data acquisition gives us new possibilities to evaluate collected data. This study shows the possibilities and potentials in using standard equipment, simple calculations and the biological stage as a measuring cell for activity determinations. Evaluation of data from Henriksdal and Bromma WWTP give some examples from the biological stage where activity can be calculated on-line. The calculation of Oxygen Uptake Rates, OUR, can be used in several ways: a) Estimation of the overall activity in the aerated part of biological stage. b) Calculations of the load of oxygen consuming substanses on the aerated basin. c) Calculation of nitrification rate. d) Estimation of necessary aerated volume. e) Rapid detection of inhibition of the nitrification (and other oxygen consuming reactions). One advantage with these calculations is the fast response to changes.

In-process measurement of parts is a field of constant research. Conventionally, industries have used traditional measuring instruments, such as vernier calipers, or even coordinate measuring machines (CMMs), to perform the control quality. In this paper, a system that is both based on machine vision techniques and integrated with a mechatronic system has been developed with the goal of automating the in-process inspection of hot-forged parts. This system uses six cameras, which are installed around the part to be measured. First, the images obtained from the cameras are processed, and thus the part’s dimensions are estimated. Then a statistical analysis is deployed in order to decide if the part may be approved or not. The experimental results validate the application of the proposed method for measuring parts during their processing in real shop floor conditions.

Novomoskovsk is one of the main centers of chemical industry in central Russia. In 2000 to control and monitor the region air quality and movement the atmosphere ecomonitorin system was created. These systems’ modifying lies in using more sophisticated technology, increasing number of observation stations and automatic sensors that determine harmful impurities. The data adequacy of airspace’s state hinges on the number of these stations and their location. The objective of our study is to estimate the data adequacy relying on modern research methods. The research involved the interpolation method of air movement control over areas which have a mixed landscape because of technology-related accidents. The method consists of 3 main stages: experimental examination of the area’s weather conditions, processing of this data using the method of air flow field recovery, and effective control of the air dynamics at man-made accidents. Air control stations gave the initial measures and current data to develop the method of air flow field recovery on the basis of the noise-resistant interpolation principle. Noise-resistant interpolation admits to errors of measuring instruments, which makes a significant magnitude when estimating meteorological data of the air. The data obtained requires to modify Novomoskovsk ecomonitoring system of the atmosphere.

Full textAbstract:
The solution of problems of diagnostics of windings of electric machines is associated with the necessity of selection of quasi-periodic test signals against the background noise. In order to highlight useful signals, as a rule, the differences in spectral compositions of signals and noises are used. Ideally, the shape of the optimal filter frequency response should coincide with the shape of the spectrum of the useful signal, which determines the complexity of such a filter. The aim of the research is to increase the accuracy of measurements and simplify the algorithmic support of measuring systems by developing a mathematical tool that makes it possible to uniquely identify and take into account errors caused by the finiteness of the measurement intervals in the processing. Determining a one-to-one relationship between local variations of signal time parameters and alterations in its spectrum parameters is believed to be the reserve of increase of sensitivity of methods of processing of quasi-periodic signals in the conditions of constant growth of computing capabilities of measuring instruments. Variations in the values of the parameters of the signals lead to a violation of the original distribution of the harmonic components, some of the latter being subjected to the greatest alterations changes, and the some other – to the smallest ones. It is proposed to increase the accuracy of measurements due to the replacement the low-sensitivity registration of alterations in the time parameters of signals with the registration of alterations in the parameters of the characteristic harmonic components of the spectrum, which have a maximum sensitivity to deviations of the controlled parameter and a minimum sensitivity to deviations caused by the instability of the measuring equipment. The mathematical tool corresponding to the practice has been developed, that makes it possible to determine unambiguously the errors caused by finiteness of measurement intervals of quasi-periodic signals. Automatic accounting of these errors makes it possible to do without complex correlation processing of quasi-periodic signals that require large computing resources (time and speed of data processing, the amount of RAM) and to ensure the accuracy of measurements.

A method of measuring crystal field parameters by means of a rotating-sample magnetometer is presented. The measurement is performed by registering 2nd, 4th and 6th harmonics of the signal that is proportional to magnetization change due to rotation of the sample in a magnetic field. Experimentally measured temperature dependence of the amplitudes of these harmonics is used to determine the crystal field parameters within the framework of the theoretical model proposed in [. The signal is detected by a digital lock-in amplifier, while temperature is controlled by a PID controller. The sample and pickup coils are located in the bore of a Halbach permanent magnet. The measurements are fully automated. Magnitude of the expected signal was estimated. Test measurements of magnetization of the Tb single crystal along a axis (in the easy crystallographic plane a-b) in the permanent magnetic field 2.7 T at room temperature were performed. The results show that sensitivity of the instruments and the proposed design of the equipment allows us to determine crystal field parameters of heavy rare-earth metals. Testing of the control software showed that computer-device communications and execution of the software blocks are correct.

Full textAbstract:
This study provides design of a low-cost and open source add-on device that enhances the functionality of the popular EVOM® instrument for transepithelial/endothelial electrical resistance (TEER) measurement. The original EVOM® instrument is designed for measuring TEER in transwell samples manually using a pair of Ag/AgCl electrodes. The inconsistency in electrode placement, temperature variation, and a typically large (12–24 h) time interval between measurements result in large data variabilities. Thus, to solve the current limitation of the EVOM® instrument, we built an add-on device using a custom designed electronic board and a 3D printed electrode holder that allowed automated TEER measurements in multiple transwell samples. To demonstrate the functionality of the device prototype, we monitored TEER in 4 transwell samples containing retinal cells (ARPE-19) for 67 h. Furthermore, by monitoring temperature of the cell culture medium, we were able to detect fluctuations in TEER due to temperature change after the medium change process, and were able to correct the data offset. Although we demonstrated the use of our add-on device on EVOM® instrument only, the concept (multiplexing using digitally controlled relays) and hardware (custom data logger) presented here can be applied to more advanced TEER instruments to improve the performance of those devices.

Terrestrial laser scanning (TLS) enables the efficient production of high-density colored 3D point clouds of real-world environments. An increasing number of applications from visual and automated interpretation to photorealistic 3D visualizations and experiences rely on accurate and reliable color information. However, insufficient attention has been put into evaluating the colorization quality of the 3D point clouds produced applying TLS. We have developed a method for the evaluation of the point cloud colorization quality of TLS systems with integrated imaging sensors. Our method assesses the capability of several tested systems to reproduce colors and details of a scene by measuring objective image quality metrics from 2D images that were rendered from 3D scanned test charts. The results suggest that the detected problems related to color reproduction (i.e., measured differences in color, white balance, and exposure) could be mitigated in data processing while the issues related to detail reproduction (i.e., measured sharpness and noise) are less in the control of a scanner user. Despite being commendable 3D measuring instruments, improving the colorization tools and workflows, and automated image processing pipelines would potentially increase not only the quality and production efficiency but also the applicability of colored 3D point clouds.
