An image forming technique using a small, flat mirror is disclosed. A real, inverted image of an object is formed with infinite depth of field when the diameter of this mirror is between 0.15 and 0.4 millimeters. In smaller diameters, this forms a diffraction pattern image of an object. The optimal ...

"This book explores the foundation, history, and theory of intelligent adaptive systems, providing a fundamental resource on topics such as the emergence of intelligent adaptive systems in social sciences, biologically inspired artificial social systems, sensory information processing, as well ...

Developed a device composed of a rod clamped in a rotatable, vertical vise, which forms the basis of a bite-board holder for vision research.

Described a timer circuit which produces pulse durations ranging from .1-20,000 msec. The timer has high reliability, is inexpensive, and simple to construct.

Discusses the rationale for a constant source of both luminance and illuminance to check photometer calibration. The inexpensive construction of such a reference source is described, and some performance data are given.

To permit on-line control of experiments with an existing high-level interpreter language, this 3-argument user function enables operation of the I/O bus, clock, and timed relays to be synchronized to external events. It also supports on-line files and machine language programs in high memory fields...

Presents data on visual discrimination of 2-pulse-interval differences.

To test whether deliberate monitoring of certain fatigue symptoms may help drivers and other workers realize when they need to rest to avoid hazard, the development of fatigue while driving a simulator was objectively measured in terms of how many of an original sample of 80 male drivers quit drivin...
