Abstract: First published nearly half a century ago, the McGraw-Hill Electronics Dictionary has served generations of scientists, engineers, technicians, educators, librarians, students, manufacturers, managers, writers, hobbyists, and others seeking accurate, up-to-date and easy-to-understand definitions for the hundreds of electronics terms not found in general language dictionaries. Now, after nearly 20 years, the fifth edition of this reference is finally available. During this time, the field of electronics has undergone such dramatic progress that entire areas of study now covered did not even exist when the fourth edition was published. More than 4,000 new entries and 100 new illustrations have been added and many outdated definitions have been revised or deleted. This dictionary focuses on words and phrases specific to the field of electronics - plus such related fields as engineering, the physical sciences, materials science and computer science. It provides information on all areas of electronics, including: fundamentals; solid-state component design and fabrication; circuit board fabrication and assembly; electronics manufacturing; product and system packaging; industrial instrumentation and control; scientific and medical instrumentation; commercial data processing; telecommunications; consumer entertainment; and military and aerospace. The dictionary includes more than 15,000 cross-referenced terms, abbreviations, synonyms and acronyms, as well as 1350 illustrations all in one handy volume. Mathematics are avoided whenever simple English can be used, and even complex concepts are defined so as to be accessible to readers at all levels of expertise.

Abstract: In an aircraft for range training of pilots in electronic warfare countermeasures, a device for simulating a threat environment on the cockpit instrumentation. The device comprises an image simulator controlling the threat azimuth indicator, and a control code receiver. The control code is transmitted via the up-link communication system from the air combat manuevering range ground station to the airborne instrumentation subsystems. The control code is recognized by the receiver and applied to the image simulator. The entire device is installed in place of the present threat signal countermeasure receiver and signal processor.

Abstract: The quality of research on groups has been notoriously poor, perhaps because of antiresearch biases of group leaders, perhaps because it is perceived as a difficult area to study (Diamond and Shapiro, 1975; Dinges and Weigel, 1971). This article is an attempt to respond to the research and evaluation deficit by providing some methodological approaches that might encourage group researchers and practitioners to attempt high quality research.

Abstract: This paper describes an automated measurement system for a micromachine, which is a laboratory model of a large turbogenerator, used for practical evaluation of proposed new control schemes involving on-line computer control. Rotor angle, slip, and various electrical quantities have to be measured rapidly and accurately, with immediate graphical display of outputs, and frequent updating for control purposes. The philosophy adopted is to present data to the computer in its most basic form, to be processed by efficient software routines.

Abstract: The surge of microprocessors into the market place may have received a lot of press coverage, but its full impact in test instrumentation is yet to be felt. The authors discuss the promise microprocessors hold for instrumentation, from the very basics to a relatively complex design for the IEEE Standard 488 (or "GPIB") Interface Bus. They also guide the designer quickly through many of the pitfalls that await the unwary, novice and expert alike.

Abstract: The commercial FT-IR market has grown to a respectable $8,000,000 annual business area. It is of importance to both the users and suppliers alike that this market continues to solidify its gains and embark into new areas and applications. This paper reviews the evolution of commercial FT-IR in the context of the over-all infrared field. The purpose of the review is to discuss the progress to date and to relate the growth of this field to the future. The future uses of the FT-IR are projected as well as the requirements for new instrumentation.

Abstract: The assembly and use of more new and versatile instrumentation systems is now enhanced dramatically with the widespread application of IEEE Standard 488-1975, "Digital Interface for Programmable Instrumentation." This Standard interface provides an easy-touse high performance concept that links instruments, calculators or computers, and peripheral devices to function as automated instrumentation systems. Microprocessor technology applied to both smart instrumentation and the implementation of IEEE Standard 488's interface functions provides still further benefits to system designers and users. This article describes both the interface function concepts important to instrumentation systems and the roles played by IEEE Standard 488 and microprocessor techniques in support of these functional concepts. Microprocessor and IEEE Standard 488 interface techniques combine to provide designers and users with significant new tools for improved product performance, something neither technology alone could provide. In the near future, special LSI chips optimized to integrate the two technologies should further enhance the benefits for all concerned.

Abstract: Transparent architecture and controllable performance are prime considerations in the design of large instrumentation. The vast amount of aspects involved, many of which need careful consideration, necessitates a design methodology. Already system reticulation into four or five goal-oriented structures, in combination with a hierarchy in design phases, can lead to sufficient control over the design effort. The methodology is also applicable to the teaching of engineering design.

Abstract: A computer-linked instrumentation system for studies of blind mobility is described. The system uses mechanical position sensing, and is capable of monitoring the position of a moving subject to within approximately 2.5 cm over a large area (80 m2). This enables the computation of quantitative performance indices based on body trajectory through the environment. Head-mounted mobility aids with auditory displays can be simulated using the system. For this purpose head orientation is monitored, and environmental obstacle positions are stored. Computer-generated signals appropriate to the type of sensory aid under study and to the obstacles present are presented via head-phones to the mobile blind or blindfolded subject.

Abstract: The attainment and enforcement of air quality standards is a complicated process. A crucial element in this process is the measurement of ambient air quality. The selection of locations for a limited number of monitors and their sampling frequencies is an important problem in the design of a regional air quality measurement system. This paper presents a mathematical model and procedure for solving the problem and demonstrates the conflicting nature of the principal guidelines specified by EPA. The method uses atmospheric simulation to assess the likelihood of standards violations, and linear programming to select the monitor locations and sampling frequencies. Since atmospheric simulation is required by EPA, the method appears to be accessible to virtually all local agencies. The use of linear programming permits extensive sensitivity analysis, which is illustrated in a case study. In particular, the trade-offs between conflicting EPA guidelines can be explicitly analyzed. The computational burden is prim...

Abstract: An instrumentation system and an improved methodology for the automatic measurement and real-time evaluation of man's postural equilibrium parameters have been developed. The system is based on the principle that the mechanical oscillations of man's physiologic gravicentre† can be translated into electrical signals, which can be recorded and analysed. The apparatus consists of an electronic platform which continuously measures the location of the physiologic gravicentre in a horizontal plane, and a circuit which reduces these measurements to quantitative indices of the postural equilibrium and displays them in numerical form immediately after the test is completed. A utomatic measurements, real-time evaluation of both amplitude and frequency of body oscillations, and operational simplicity are essential features of this instrumentation. The system could be used in various specialized disciplines, such as clinical medicine, otorhinolaryngology, industrial, aerospace and undersea medicine, as well as sports...

Abstract: Originally the Group Therapy Outcome Instrument (GTOI) was based upon the senior author’s interest in developing a systematic set of guidelines for appraising the conceptual and methodological sufficiency of outcome studies in group psychotherapy. Reviews of the literature over the years had continued to document the disquietingly inadequate quality of research on group outcome as the author experimented with alternative forms of the instrument. After several years of expansion and revision a preliminary version of the GTOI was completed. At that point the second author, along with several graduate students enrolled in his didactic-practicum course in group psychotherapy, were contracted to conduct a comprehensive review of the group treatment literature, and to use the GTOI in evaluating the adequacy of the studies
