Filed:

Mar 9, 1993

Appl. No.:

8/028451

Inventors:

Lawrence M. Frazier - West Covina CA
James B. Sheffler - Chino CA
Ronald F. Carlson - Highland CA

Assignee:

Hughes Missile Systems Company - Los Angeles CA

International Classification:

G01S 1389

US Classification:

342 59

Abstract:

A three dimensional imaging radar system and method for generating and processing radar information to produce a three dimensional image of objects viewed by the system. The system is designed to create three dimensional images of physical objects at relatively short range, up to a distance of about 1000 feet. The radar system comprises a servo controlled antenna system, wherein the servo system provides azimuth and elevation pointing angle output signals. Two radar transmitters provide radar signals in two different radar bands that are selectively transmitted by the antenna system as a radar beam. A radar receiver preprocesses radar return signals reflected from targets. A digital signal processor is provided that processes the radar return signals from targets and which embodies system improvements comprising a Fourier transform processor, a coherent integrator that provides low pass and high pass filtering to reduce noise, a detector comprising a digital Pythagorean processor that converts the radar return signals into amplitude values for each range bin, a noncoherent integrator, and an adaptive threshold comparator. A buffer memory is is provided that has a predetermined number of range cells that store the amplitude of the radar return signal at each range. A digital scan converter comprising a three dimensional coordinate converter converts the azimuth and elevation pointing angle signals into x, y and z addresses of radar signals that are stored in the buffer memory.

Assignee:

Speech Systems, Inc. - Tarzana CA

International Classification:

G10L 300

US Classification:

381 46

Abstract:

The present invention is directed to an apparatus and method which provide repeatable control of speech input to a microphone via audio feedback to a user. In this manner, repeatable and simultaneous control of microphone positioning and speaking volume is obtained. In a first embodiment, a microphone in the mouthpiece of the handset is used to detect sounds emanating from the mouth and audio feedback is provided through a speaker in the handset earpiece to ensure the microphone is positioned correctly for the application. In alternate embodiments, feedback is provided based upon voiced and unvoiced amplitudes of the input speech to obtain more optimal results.

Appl. No.:

5/516595

Inventors:

Ronald G. Carlson - South Gate CA

International Classification:

A63C 1706
A63C 126

US Classification:

280 1122

Abstract:

A roller skate having a frame mounting heel and toe sections which are independently adjustable to accommodate different foot and shoe sizes and wheels having spring supported axles whose ends are releasably positioned in slots in the frame in such a way as to permit rapid removal and replacement of the wheels. The heel section has a rigid ankle support and the toe section has a rigid toe receiving portion which are uniquely constructed and arranged to permit the skate to be worn safely with or without shoes.

Appl. No.:

6/642703

Inventors:

James E. Clifton - El Cajon CA
Ronald F. Carlson - San Diego CA

Assignee:

General Dynamics Corporation/Convair Div. - San Diego CA

International Classification:

B23B 4514

US Classification:

408 14

Abstract:

A nosepiece for a drill motor. The nosepiece is adjustable to allow the nosepiece length to be changed rapidly to compensate for different drill lengths. The nosepiece is threaded to mate with threads on the drill motor housing and can be adjusted longitudinally along the motor center line axis. When the nosepiece is threaded along the housing to a desired location it is locked in place by a locking ring keyed to the nosepiece and fixed in position on the drill motor housing by a hand adjustable set screw.

Inventors:

Ronald F. Carlson - La Jolla CA

Assignee:

General Dynamics Corporation/Convair Div. - San Diego CA

International Classification:

B23B 4504

US Classification:

408 14

Abstract:

A feed rate attachment for a drilling tool or the like. The drilling tool is equipped with a piston attached thereto operating within a cylinder positioned against the work-piece. A hydraulic damper is utilized to linearly resist the movement of the drilling tool attached piston relative to the cylinder.
