Noncontact position measurement systems using optical sensors
Optical and computational components are combined to form high precision, six degree-of-freedom, single-sided, noncontact position measurement systems. Reflective optical targets are provided on a target object whose position is to be sensed. Light beams are directed toward the optical targets, producing reflected beams. Electrical signals are produced by movements of reflected beams across position-sensitive detectors, such as lateral-effect photodiodes. The signals are transformed to provide measurements of translation along and rotation around three nonparallel axes which define the space in which the target object moves.Board of Regents, University of Texas Syste
Out of Time: Work, Temporal Synchrony and Families
Drawing on data from in-depth interviews with seafarers and their partners, this article examines the impact of routine absence on couple and family relations. Using the lens of time, we identify how work patterns and extended absence lead to temporal desynchrony and fragmentation of the life course. We examine how seafarers' lives are both continuous and fractured and often out of step with lives at home.Temporal desynchrony was exemplified in reduced opportunities for couples jointly to produce temporal markers and share in significant calendar events. This lack of temporal harmony posed a challenge to family relations.These findings draw attention to the need for further research that embraces a more multifaceted understanding of time in the context of work and family life
