Abstract
A sensing system generates location signals indicative of where an electrically-powered, mobile device is in a venue. A control system determines that the mobile device is at rest when the location signals are substantially the same for a predetermined period of time, processes the location signals to determine an accurate, current location of the mobile device in the venue when the mobile device is determined to be at rest, and controls the mobile device when determined to be at rest to operate in a low power mode in which the average electrical power consumption of the mobile device is reduced.
Claims20
An arrangement for accurately locating, and for reducing average electrical power consumption of, an electrically-powered, mobile device at rest in a venue, the arrangement comprising:
- a sensing system for generating location signals indicative of where the mobile device is in the venue, wherein the sensing system includes a locationing system deployed in the venue;
- and
- a control system operatively connected to the sensing system for determining that the mobile device is at rest when the location signals are substantially the same for a predetermined period of time, for processing the location signals to determine an accurate, current location of the mobile device in the venue when the mobile device is determined to be at rest, and for controlling the mobile device when determined to be at rest to operate in a low power mode in which the average electrical power consumption of the mobile device is reduced.
(canceled)
A method of accurately locating, and of reducing average electrical power consumption of, an electrically-powered, mobile device at rest in a venue, the method comprising:
- generating, via a sensing system including a locationing system deployed in the venue, location signals indicative of where the mobile device is in the venue;
- determining, via the sensing system and a control system operatively connected to the sensing system, that the mobile device is at rest when the location signals are substantially the same for a predetermined period of time;
- processing via the control system, the location signals to determine an accurate, current location of the mobile device in the venue when the mobile device is determined to be at rest;
- and
- controlling, via the control system, the mobile device when determined to be at rest to operate in a low power mode in which the average electrical power consumption of the mobile device is reduced.
(canceled)
The method of claim 14, wherein the determining that the mobile device is at rest is performed by determining when received ultrasonic ranging signals are substantially the same for the predetermined period of time.
