The implementation of calculation architectures, data acquisition and processing systems, VLSI type integrated circuits within driving systems shows and increased trend in the industry, due to the advantages of such circuits compared to microcontrollers and ASIC’s. In the first part of the paper is presented functional aspects of reconfigurable integrated circuits for monitoring, controlling and managing industrial processes. Compact RIO is a device developed by National Instruments and which is intended for monitoring and controlling industrial processes. This is also an “embedded” type system, which comprises a FPGA device, a processor with real-time operating system (RTOS) and various input-output modules which have to be attached by the user. Applications using such devices, usually also use an HMI (human machine interface) for creating a graphical interface with the user. The second part of the paper is allocated for establishing the requirements for using of such system in the explosive atmospheres. The practical achievement consists in the construction of a wirelessly PC-controlled robot and the analysis of measurements achieved, respectively data acquired from sensors and video recordings. Among conclusions is highlighted the opportunities brought by the use of the intrinsic safety and flame proof types of protection.

In the teaching-learning process at the upper and upper secondary levels, it is difficult to motivate students about the importance of knowing and applying basic concepts in industrial processes. Therefore, it is proposed how to apply the concept of light polarization and spectroscopy to visualize the differences between substances based on sucrose or fructose. Both techniques have been applied in various industrial processes; their cost is regularly high and require extensive training. In this paper, we present the results of the implementation of a low cost linear polariscope for the analysis of natural bee honey and syrups based on sucrose. The arrangement consists of a semiconductor laser, a photodiode, two polarizers, a stepper motor and some mechanical elements, all controlled by the computer through a graphical interface. To validate the results, an optical array based on a low-cost commercial spectroscope is used. By implementing this experimental arrangement, the concepts of polarization, optical activity, atomic-molecular physics, electronic instrumentation and principles of equipment design and construction are involved.

The current work examines a methodology developed for assessing driver attention management using high-precision eye glances towards safety-relevant driving information. The Task Analysis Eye Movement Overlay (TAEMO) method uses task analyses, video recordings of a driving scenario, and eye glance data toward visual keys that drivers sample during the driving scenario to directly measure driver engagement. This methodology has applications for evaluating infrastructure design, driver impairment assessment, driver training, driver distraction research, and vehicle human-machine interface (HMI) system design.

Recently, the claim was put forward that grammar emerges from embodied conduct. This has led to a discussion in multimodal conversation analysis and interactional linguistics whether the routinization of embodied actions can be described in terms of grammar and grammaticalization. While particular items such as exophoric demonstratives and gestures are routinely delivered as multimodal constructions, i.e., as part of grammar, it is debatable whether this also holds for other candidates: e.g., loose couplings of verbal and embodied conduct, locally routinized, or ephemeral gestalts that do not endure beyond the context of their use. My paper contributes to this discussion by proposing a distinction between two kinds of multimodal gestalts: socially sedimented multimodal gestalts (multimodal constructions), and locally assembled, ephemeral multimodal gestalts. To this end, I examine sedimented couplings of demonstratives and embodied practices in instructions, and the change of a locally assembled format over time. The data are in German and come from 12 h of video-recordings of self-defense trainings for young women. In the course of the participants’ interactional history, the multimodal format of the participants’ actions changes. The changes concern formal and functional aspects of the resources used to accomplish those actions, their multimodal orchestration, and the temporality of their delivery. The paper makes four claims: 1. In their primordial use in co-present interaction, demonstratives are coupled with embodied practices and request addressees’ attention to the speaker’s body, i.e., they are tightly and intercorporeally coupled with the embodied conduct of the participants; 2. gesturally used demonstratives are socially sedimented multimodal gestalts, i.e., multimodal constructions; 3. multimodal gestalts may be subject to transformations in the course of multiple repetitions; 4. in my data, the transformations lead to the emergence of a new, reduced format, which, while being locally routinized, is neither grammatical nor grammaticalized.

Brain-Computer Interface (BCI) plays a major role in current technologies such as rehabilitation, control of devices, and various medical applications. BCI or brain-machine interface provides direct communication between a brain signal and an external device. In this paperwork, a detailed survey was carried out with the design of single-channel EEG system for various applications. Also, this paper mainly focused on the development of single-channel electroencephalography (EEG) signal acquisition system which includes a preamplifier, bandpass filter, post-amplifier and level shifter circuits. The design of the preamplifier and post-amplifier circuit was carried out by integrated circuits (IC) such as instrumentation amplifier IN128P and bandpass filter with the help of low power operational amplifier LM324. The developed single-channel acquisition board was tested by acquiring an electrooculogram (EOG) signal with closed and opened eye conditions. The acquired signal is displayed and stored in the computer with the help of the HBM-DAQ unit.

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.

One measure of the maturity of a device technology is the ease and reliability of applying contact metallurgy. Compared to metal contact of silicon, the status of GaAs metallization is still at its primitive stage. With the advent of GaAs MESFET and integrated circuits, very stringent requirements were placed on their metal contacts. During the past few years, extensive researches have been conducted in the area of Au-Ge-Ni in order to lower contact resistances and improve uniformity. In this paper, we report the results of TEM study of interfacial reactions between Ni and GaAs as part of the attempt to understand the role of nickel in Au-Ge-Ni contact of GaAs.N-type, Si-doped, (001) oriented GaAs wafers, 15 mil in thickness, were grown by gradient-freeze method. Nickel thin films, 300Å in thickness, were e-gun deposited on GaAs wafers. The samples were then annealed in dry N2 in a 3-zone diffusion furnace at temperatures 200°C - 600°C for 5-180 minutes. Thin foils for TEM examinations were prepared by chemical polishing from the GaA.s side. TEM investigations were performed with JE0L- 100B and JE0L-200CX electron microscopes.
