Device For Modular Input High-Speed Multi-Channel Digitizing Of Electrical Data
US Patent:
5453744, Sep 26, 1995
Filed:
Nov 23, 1993
Appl. No.:
8/156048
Inventors:
Alan L. VanDeusen - Lee's Summit MO
Charles E. Crist - Waxahachie TX
Charles E. Crist - Waxahachie TX
Assignee:
AlliedSignal Inc. - Morristown NJ
International Classification:
H03M 112
US Classification:
341155
Abstract:
A multi-channel high-speed digitizer module converts a plurality of analog signals to digital signals (digitizing) and stores the signals in a memory device. The analog input channels are digitized simultaneously at high speed with a relatively large number of on-board memory data points per channel. The module provides an automated calibration based upon a single voltage reference source. Low signal noise at such a high density and sample rate is accomplished by ensuring the A/D converters are clocked at the same point in the noise cycle each time so that synchronous noise sampling occurs. This sampling process, in conjunction with an automated calibration, yields signal noise levels well below the noise level present on the analog reference voltages.
Miniature Personal Display
US Patent:
6229503, May 8, 2001
Filed:
Aug 25, 1998
Appl. No.:
9/139372
Inventors:
Robert Mays - Albuquerque NM
Charles E. Crist - Waxahachie TX
Charles E. Crist - Waxahachie TX
International Classification:
G09G 500, G02B 2714
US Classification:
345 7
Abstract:
A personal display device miniaturized to allow the projection of images directly on the viewer's retina which is a compact and versatile device that further minimizes the potential for total immersion. The display device can be selected for use in the monitor mode or full video and full color or monochrome operation. The invention utilizes miniaturized 2D laser arrays integrated with nonlinear optical processes combining semiconductor technology with optics technology.
