US Patent:

8335638, Dec 18, 2012
Filed:

Feb 22, 2010
Appl. No.:

12/710222
Inventors:

Richard D. Ridenour - Glendale AZ, US
Peter Bobrowitz - Cave Creek AZ, US
Assignee:

Aviation Communication & Surveillance Systems LLC - Phoenix AZ
International Classification:

G08G 5/00
G06F 19/00
US Classification:

701120, 701 9, 701300, 340945
Abstract:

A system according to aspects of the present invention includes a processor, a user interface (including a display) in communication with the processor, and a memory in communication with the processor. The processor executes instructions stored in the memory to present a first symbol on the display of the user interface that indicates the bearing to an off-scale vehicle, and to present a second symbol on the display that indicates the path of travel of the off-scale vehicle. The present invention provides a more accurate representation of the bearing and track of off-scale traffic compared to conventional traffic display systems.

US Patent:

56546726, Aug 5, 1997
Filed:

Apr 1, 1996
Appl. No.:

8/626304
Inventors:

Peter David Bailey - Phoenix AZ
Paul William Schwerman - Phoenix AZ
Peter James Bobrowitz - Glendale AZ
Assignee:

Honeywell Inc. - Minneapolis MN
International Classification:

H03F 304
US Classification:

330289
Abstract:

A novel bias circuit provides precise base emitter voltage(V. sub. BE) which tracks the temperature coefficient of an RF transistor using low cost devices. The bias circuit includes a precision current source which injects current through a P-N junction device to derive a temperature compensating reference voltage thereacross. The P-N junction device is isolated from current fluctuations using a current isolation circuit coupled between the P-N junction device and the base of the RF transistor. The diode is thereby isolated from and unaffected by changes in the base current of the RF transistor. Multiple RF transistors are biased from the single P-N junction device by replicating only a trimming potentiometer and the current isolation circuitry for each additional RF transistor to be biased.
