53230752, Jun 21, 1994

Filed:

Nov 20, 1992

Appl. No.:

7/987482

Inventors:

Joseph Denk - Los Angeles CA
Richard J. Grant - Los Angeles CA

Assignee:

AlliedSignal Inc. - Morris Township, Morris County NJ

International Classification:

H02K 1100
H02K 528
H02K 112

US Classification:

310 68B

Abstract:

A two-pole toothless PM machine employs Hall effect sensors to indicate the position of the machine's rotor relative to power windings in the machine's stator. The Hall effect sensors are located in the main magnetic air gap underneath the power windings. The main magnetic air gap is defined by an outer magnetic surface of the rotor and an inner surface of the stator's flux collector ring.

Appl. No.:

7/107314

Inventors:

Richard W. Grant - Manhattan Beach CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

F16H 3706
F01B 2104

US Classification:

74661

Abstract:

Motors (42,44) each have a pinion driving ring gear (62). Motor (42) is mounted on the platform and motor (44) is mounted on ring gear carrier (56). Rotation of either motor rotates carrier (56), hubs (40) and shaft (30).

Appl. No.:

6/604638

Inventors:

Richard B. Grant - Sherman Oaks CA

International Classification:

G06F 3153

US Classification:

364200

Abstract:

A computer system including text input and display devices. A display manager receives text from the input device and causes the display device to display that text on a first display level. The display manager also causes other display levels to be displayed so that they are perceived as being successively posteriorly positioned relative to the first level. Text received from the input device is also accumulated and compared to previously stored text segments to cause performance of program task elements that are associated with the stored text segments matching the received text. The display manager causes text produced by the performed task elements to be directed to and perceptually represented on the appropriate posterior display levels.

Appl. No.:

6/693954

Inventors:

Richard W. Grant - Manhattan Beach CA
Allen G. Storaasli - Hermosa Beach CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

F16H 3300

US Classification:

342352

Abstract:

Apparatus is provided for simultaneously rotating a plurality of parallel shafts connected, for example, to an array of rf switches that feed energy to or from an array of antenna feed horns. Each shaft is connected by a separate crank to a planar drive plate that is controllable moved relative to the switches in an orbiting fashion, to rotate the shafts in unison. The drive plate is controllably moved by a motor drive system that includes an orbiting motor secured to the plate and a base motor secured to a fixed substrate that houses the switches. The output shafts of the two motors are coupled together such that operation of either motor moves the orbiting motor, and thus the drive plate, in an orbiting motion about the base motor and substrate.
