Abstract: A method and apparatus is provided for power conservation of a hardware module (142) which is coupleable to a portable electronic device (100). The hardware module (142) has unique identification information associated therewith and stored therein. The unique identification information is provided periodically (308) to the portable electronic device (100) and stored therein (207). To conserve power, the portable electronic device (100) sends a power-down notice (212) to the hardware module (142), the module controller (144) stores current state information of the hardware module (142) in a non-volatile memory (146) thereof, and the hardware module (142) is powered off (214).

Abstract: A method for determining location technology supported by a wireless communications network including sending (505) a location request, for example a MO-LR request, from a mobile wireless subscriber device to the network, receiving a network response (515) in reply to the location request, determining the subscriber device location technology supported by the network from the network response (535, 550), and in some embodiments the location technology of the subscriber device is controlled based on the technology supported by the network.

Abstract: A communication device (101) includes a display (103) screen for displaying images to a user; an image input (105) for detecting and capturing a series of images, including a prior image and subsequent images; and a processor (107). The processor (107) is configured to facilitate receiving, from the image input (105), the series of images; to facilitate displaying images received from a receiver (111) on the display (103) screen; and to facilitate determining whether the subsequent images have changed in a pre-determined manner from the prior images. A window can be provided on the display, for example to display the series of images from the image input (105). The presence or absence of the window is controlled by a determination that the subsequent images have changed in the pre-determined manner from prior images. When the images are changed, the window is deployed on the display, and when the images are stable, the window is removed from the display.

Abstract: The present invention provides a method and apparatus for generating time of arrival estimates for use by a wireless communication network for locating the position of a wireless or mobile source (102) within the service area of the wireless communication network. The mobile source generates time of arrival estimates from data bursts received from base sites (100) operating within the network. In at least one embodiment, the mobile source (102), then, communicates the time of arrival estimates for each of the base sites (100) to the network, from which the location of the mobile source (102) is determined. In at least some instances, the mobile units additionally determine a variance estimate for each time of arrival estimates, which is representative of the degree of confidence in the time of arrival information being supplied to the network.
