Filed:

Sep 9, 2000

Appl. No.:

09/658540

Inventors:

James Chester Meador - Berkeley CA
Giovanni Gozzini - Berkeley CA
Marco Sabatini - Kensington CA

Assignee:

STMicroelectronics, Inc. - Carrollton TX

International Classification:

H02H 902

US Classification:

361 931, 382124

Abstract:

Current drawn by the fingerprint sensor subject to electrostatic discharge events not fully dissipated by a pad ring is monitored. Upon detection of an overcurrent (e. g. , an increase in the current drawn by approximately an order of magnitude) indicating that a latchup condition has occurred, power is removed from the sensor, together with all inputs to the sensor, until the latchup condition is cleared. If a processor or controller is employed by the sensor, the processor or controller is concurrently reset since a firmware crash may be induced by the latchup condition. If a parallel port or other communications connection is employed by the sensor, the overcurrent signal is employed to directly disconnect power and input signals to the sensor.

International Classification:

G06F 3/01

US Classification:

345156

Abstract:

Methods and systems for providing a light device that can emit light and sense light are disclosed. In one embodiment, a lighting device includes a light guide having a planar first surface, the light guide configured such that at least some ambient light enters the light guide through the first surface and propagates therein, and at least one light detector disposed along an edge of the light guide, the at least one detector optically coupled to the light guide to receive light propagating therein. The light detector can be configured to produce a control signal. In some embodiments, the lighting device also includes at least one light turning feature disposed on the first surface, the at least one light turning feature configured to direct light incident into the light guide through the first surface.

Appl. No.:

13/544850

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G01S 3/02

US Classification:

342458

Abstract:

Processing associated with ranging operations is shifted from a first apparatus to a second apparatus. For example, upon sampling a received ranging signal (e.g., a pulse) from the second apparatus, the first apparatus does not process the ranging signal to identify a relatively precise time of arrival estimate. Instead, the first apparatus sends sample data (e.g., representative of the power and/or magnitude of the received signal) and associated timestamp information to the second apparatus. The second apparatus processes the received sample data and timestamp information to determine the time of arrival estimate on behalf of the first apparatus. The second apparatus then uses this time of arrival estimate to determine the distance between the apparatuses.

Appl. No.:

9/657563

Inventors:

James Chester Meador - Berkeley CA

Assignee:

STMicroelectronics, Inc. - Carrollton TX

International Classification:

H02J 700

US Classification:

320118

Abstract:

An electronic device battery pack for a battery requiring cycling to prolong lifetime is divided into at least two parallel cells for which the charging state is automatically maintained. When external power is available and one or more cells is substantially discharged, the substantially discharged cell(s) are selected one at a time to be fully drained and recharged. A partially discharged but not substantially discharged cell will be left in that state until use of the electronic device has substantially discharged the cell. Once a cell has been recharged, the next substantially discharged cell is drained and recharged, and so on until all cells are fully charged. If the charging of a cell is interrupted by removal of the external power, another cell is utilized to provide power to the electronic device and recharging is resumed once the external power is restored. A device kept in a charging cradle except when being utilized may thus be used and returned to the charging cradle without adversely impacting battery life.
