Motion detecting wireless receiver and signal monitoring method therefor
First Claim
Patent Images
1. A method comprising:
- monitoring, at a receiver, for at least one transmission from a plurality of stations, wherein the monitoring is performed at a series of time points defined by a first time schedule in order to determine one station in the plurality of stations with which to communicate;
determining, independently of the monitoring, if the receiver is not moving; and
continuing the monitoring by adjusting, in response to a determination that the receiver is not moving, the series of time points according to a second time schedule, wherein the series of time points defined by the second time schedule comprises time points that are separated by longer time intervals than the series of time points defined by the first time schedule.

Abstract
A portable wireless transceiver (104) includes a receiver (206) for monitoring transmissions from neighboring transceivers (106A and 106B) to select a transceiver to use for communications. The portable wireless transceiver (104) further has a motion detector (204) for determining whether or not the portable wireless transceiver (104) is moving. If the portable wireless transceiver (104) is determined to not be moving, a processor (202) alters a schedule for monitoring of neighboring transceivers (106A and 106B) so that the monitoring is performed less frequently, thereby reducing power consumption by the portable wireless transceiver (104).

9. A wireless receiver, comprising:
-
a receiver for monitoring for a transmission from a plurality of stations at a series of time points, wherein the series of time points is defined by a first time schedule; a motion detector for determining, independently of the monitoring of the receiver, if the receiver is not moving; and a transmission monitor scheduler, communicatively coupled to the accelerometer and the receiver, for adjusting, in response to a determination that the receiver is not moving, the series of time points according to a second time schedule, wherein the series of time points defined by the second time schedule comprises time points that are separated by longer time intervals than the series of time points defined by the first time schedule. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
