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.

Abstract: A user moves about a venue, and operates a mobile reader to read a product tag in a read zone of the mobile reader. An identifier, such as a user identity badge, is associated with the user to identify the user. A sensing system is deployed in the venue for sensing the location of the identifier. A host server associates the mobile reader with the identifier of the user operating the mobile reader, and determines a location of the product tag in the venue based on the read zone and the location of the identifier.

Abstract: Radio frequency identification (RFID) tags that pass through a portal in a venue are read by a portal RFID reader, and identified as being tags having a higher priority as compared to other RFID tags in the venue that have a lower priority. The identities of the high-priority tags are transmitted to an overhead RFID reader, which preferentially reads the high-priority tags over the low-priority tags in the venue. Only the high-priority RFID tags are located and tracked in the venue.

Abstract: Multiple sensing network units are deployed overhead in a venue. Each unit supports a motion detecting system for detecting a level of motion in a zone of the venue, and an RFID locationing system for reading RFID tags in the venue, in response to the motion level detected by the motion detecting system. The performance of the RFID locationing system is adjusted and optimized in response to the detected motion level.

Abstract: A mobile device can be found and recovered by executing a recovery action indicative of at least one location of the mobile device. An interface displays the location of the mobile device.

Abstract: Multiple sensing network units are deployed overhead in a venue, in which RFID tags of interest and RFID product tags are also deployed. Each unit supports an RFID locationing system for reading the product tags in a reading mode of operation with a set of reading parameters, for reading the RFID tags of interest in the venue, for changing at least one of the reading parameters in response to reading an RFID tag of interest that is proximal to a zone of interest, and for reading with emphasis the product tags that are in the zone of interest with the changed reading parameter.

Abstract: Video cameras are distributed throughout a venue. Each camera is operated under control of a host server to capture a video stream of images of targets at a frame rate and resolution. The server also controls radio frequency identification tag readers and item locationing devices in the venue. A level of utilization of a central processing unit and/or of a memory of the server is detected when the server is controlling the readers, locationing devices, and cameras. The frame rate and/or the resolution of one or more of the cameras are adjusted as a function of the detected level of utilization. The server performs at maximum performance in normal operation when few targets are captured by the cameras, and at less than maximum performance in a worst case condition when multiple targets are captured by the cameras, and gradually reduces its performance from normal operation to the worst case condition.
