Weight and power savings shaft encoder interfacing techniques for aerospace applications

Many aerospace applications for shaft angle digitizers such as optical shaft encoders require special features that are not usually required on commercial products. Among the most important user considerations are the lowest possible weight and power consumption. A variety of mechanical and electrical interface techniques that have large potential weight and power savings are described. The principles to be presented apply to a wide variety of encoders, ranging from 16 to 22 bit resolution and with diameters from 152 to 380 mm (6 to 15 in.)

University faculty and administrator responses to job strains

This study reports the relationships between job strain and several quality of life (QOL) indicators for a group of university faculty and administrators. The QOL indicators were in the domain of job satisfaction, life satisfaction, and health. Variables presumed to moderate the relationship between job strain and QOL were tested for their ability to buffer the strain effects. Analyses were carried out on faculty's and administrators' responses. The strong correlations obtained have both theoretical and practical consequences. Intervention strategies are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43599/1/11162_2004_Article_BF00991876.pd

Characteristics and Application of "Smart" Shaft Encoders

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, NevadaA family of absolute optical shaft encoders has been configured which is based upon an electro-optical multiplexing architecture. When interfaced to a microprocessor, the resulting "smart" encoder can perform several allied data processing functions and can replace many types of electro-mechanical components. Encoder architecture, interfacing, and several allied signal processing examples are discussed.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
