Filed:

Feb 1, 1978

Appl. No.:

5/874110

Inventors:

Ronald DeCrescent - Northridge CA

International Classification:

G01D 2104

US Classification:

250222R

Abstract:

One embodiment of the subject invention comprises a device in which the passage of an object through first and second closely spaced parallel, pulsed, infrared beams is detected, to provide an elapsed time and/or speed indication. The beams are synchronously pulsed at a sufficiently high frequency that the interpulse periods are relatively short compared to the anticipated minimum elapsed time of the passage of the object through the beams, and beam interruptions are detected within a single interpulse period. In one embodiment of the invention, a third beam, in conjunction with one of the other two beams, is used to measure a second speed value, which is compared to the speed value measured between the first and second beams so as to ascertain if the object is accelerating or decelerating. Measured speed values are displayed on a multiplexed, multi-segment display, as well as being applied to a calculator or processor unit for the computation of preselected functions of the measured speed values. The display also provides an indication as to whether the object is accelerating or decelerating.

Abstract:

A portable compact target motion simulation system, adapted to generate simulated target motion for displaying, tracking, and controlling a plurality of simulated targets on a display device for training purposes. The system is operable to generate pre-programmed and dynamic exercises, for training trainees in operating tracking devices, to develop trainee skill in analyzing and responding properly to target motion. The apparatus is totally programmable, and capable of providing targets in any matrix. It includes a target display generator, adapted to store, merge, and transmit timed data signals for driving a target-display device. It further includes a dynamic target motion generator, microprocessor-based, adapted to receive input data identifying the characteristics of particular operator-controlled targets and convert such data into dynamic target motion input data for driving the target display generator. A remote input device, microprocessor-based, enables the operator to interface with and control the functions of particular targets in the target display generator, by inputting target motion initiation and modification data into the dynamic target motion generator, for generating a display to train the trainee. The apparatus further includes a pre-programmed target motion generator, microprocessor-based, operable in conjunction with a data storage and retrieval device, to generate pre-programmed target motion for demonstrating certain target motion functions, or as a background for dynamic target motion for driving the target display generator, or to store data from the pre-programmed target motion generator and dynamic target motion generator after display thereof, for subsequent debriefing purposes.
