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.

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.

Abstract: Apparatus and method to determine a distance to a second apparatus that is movable. The apparatus and method may detect a range request transmitted between a third apparatus and the second apparatus, wherein the third apparatus is geographically fixed, detect a range response transmitted between the second apparatus and the third apparatus in response to the range request, and determine the distance to the second apparatus based on the detected range request and range response at the apparatus.

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.
