20040204051, Oct 14, 2004
Filed:

Aug 27, 2002
Appl. No.:

10/229610
Inventors:

Clifton Scott - San Diego CA, US
Scott Hackman - San Diego CA, US
International Classification:

H04B001/38
US Classification:

455/556100, 455/551000, 455/418000
Abstract:

A wireless communication device has logic that preferentially obtains provisioning information from a removable user identification module if one is provided, and otherwise obtains provisioning information resident in a permanently installed onboard non-volatile memory such as a flash memory device.

US Patent:

53732596, Dec 13, 1994
Filed:

May 5, 1993
Appl. No.:

8/057028
Inventors:

Scott Hackman - Carlsbad CA
Anthony J. Estrada - San Diego CA
Assignee:

Qualcomm Incorporated - San Diego CA
International Classification:

H03B 518
H03L 7099
US Classification:

331 36C
Abstract:

A voltage controlled oscillator comprises more than one dissimilar diode. The dissimilar diodes have different capacitance versus voltage characteristic shapes. The dissimilarity causes the tuning gain factor of the resulting oscillator to be an increasing function of increasing frequency. Such an oscillator when properly incorporated into a phase lock loop can yield loop parameters which are a constant function of increasing frequency.
