Filed:

Aug 2, 2001

Appl. No.:

09/921971

Inventors:

Leonid Sheynblat - Belmont CA
Thomas George Wolf - Mountain View CA

Assignee:

SnapTrack, Inc. - Campbell CA

International Classification:

H04B 138

US Classification:

455574, 455404, 455521, 455456, 3423571

Abstract:

Reserve power is provided in a portable cellular transceiver comprising a Global Positioning System (GPS) receiver by monitoring a power level of a battery of the portable cellular transceiver using a power detection circuit. A comparator circuit determines whether the power level of the battery is greater than a predetermined threshold. Based on the available power level, a power control circuit automatically places the transceiver into at least one low power mode when the power level reaches a corresponding threshold level. The low power mode selectively powers down circuitry of the portable cellular transceiver. The corresponding threshold level reserves power for an emergency telephone call. Power is provided to the circuitry of the portable cellular transceiver when the available power level is greater than the predetermined threshold. The reserve power provides power for the activation of the portable cellular transceiver, establishment of a call between the portable cellular transceiver and a cellular base station, transfer of GPS satellite acquisition aiding information to the portable cellular transceiver, receipt of GPS satellite information, communication of GPS satellite information to the cellular base station, and determination of a position of the portable cellular transceiver.

Appl. No.:

11/538436

Inventors:

Norman F. Krasner - Emerald Hills CA, US
Thomas G. Wolf - Mountain View CA, US
Leonid Sheynblat - Hillsborough CA, US

Assignee:

QUALCOMM, Incorporated - San Diego CA

International Classification:

H04M 11/04

US Classification:

4554042, 4554041

Abstract:

A method and apparatus for providing emergency notification by a wireless mobile device in response to triggering a sensor. A detection system, which may be located within a vehicle, comprises one or more sensors configured to sense an emergency event and transmit a message via a wireless link regarding the emergency event. For example, the wireless mobile device may be programmed to call a predetermined emergency number such as E911, and transmit data including position and other information from the mobile device to the emergency number in response to the received message.

Inventors:

Leonid Sheynblat - Hillsborough CA, US
Thomas G. Wolf - Mountain View CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G06F 1/26

US Classification:

713323

Abstract:

A power management device useable in a mobile station includes a main processor configured to execute applications including signal processing applications and further configured to enter a sleep mode in response to predetermined criteria. The device further includes a circuit configured to operate when the main processor is in the sleep mode comprising at least one of a low power processor and a sensor to monitor at least one of signals, commands, inputs, and changes in environment, the circuit waking up the main processor responsive to one of the low power processor and the sensor. The device may operate a method and may execute instructions based on a machine readable medium.
