Abstract: An inventory management system is described that includes two or more cameras mounted on a retail display space. The cameras are positioned to capture images showing the presence of items of interest in the retail display space. A hub is in communication with each of the cameras mounted on the retail display space and is operable to aggregate information from the cameras related to the items of interest in the retail display space, and to communicate data regarding the status of the item of interest to an inventory management system operable to receive the data from the hub.

Abstract: A system for tracking mobile assets is described. The system includes a plurality of mobile asset tracking devices, where each of the tracking devices has a short range radio transmitter used to transmit identifying information to other nearby tracking devices. A subset of the plurality of mobile asset tracking devices also include location determination modules and wide area network communications transmitters, this subset of mobile asset tracking devices is operable to collect the identifying information of the nearby tracking devices without the wide area network communication transmitter and to transmit the location and identifying information of the nearby tracking devices to a monitoring center to track the plurality of mobile asset tracking devices.

Abstract: A system and method for determining a location of a mobile device is described that attempts to determine the location of the mobile device using a variety of location determination technologies according to a hierarchy of location determination technologies, where the most accurate technologies are attempted before less accurate technologies until a location determination is made for the mobile device. The hierarchy of location determination technologies includes each of: autonomous GPS, assisted GPS, primary carrier network location based services, tri-lateration, secondary carrier network location based services, and serving base station location.
