20090312032 | Optimizing Battery Life and Network Resources During Position Location Tracking Scenario - An apparatus and method for optimizing battery life and network resources during position tracking is disclosed. The position of a target being tracked is compared with a predefined geofence boundary. If the position of the target is far from the geofence boundary, position fix of the target is calculated using low quality of service (QoS) parameters. If the position of the target is not far from the geofence boundary, position fix of the target is calculated using high quality of service (QoS) parameters. | 12-17-2009 |
20100115096 | RESOURCE SHARING OVER WIRELESS PERSONAL AREA NETWORKS - Apparatuses and methods to establish and share resources over a personal area network are provided. The units sharing similar functions or common applications are connected by a personal area network such as a ZigBee network such that a selected one of the units sharing the functions or applications runs the application or function for each of the connected units. the similar function or common applications may include, for example, location determinations, data transmission, or the like. The selection of the one unit to run the application may be based on battery charge, processor capacity, or the like. | 05-06-2010 |
20100250134 | DEAD RECKONING ELEVATION COMPONENT ADJUSTMENT - The subject matter disclosed herein relates to adjusting an elevation component of a estimated location based, at least in part, on sensor-based dead reckoning. | 09-30-2010 |
20100273418 | STATIC NODES POSITIONING IN A WIRELESS NETWORK - Positions in a region serviced by a short range wireless network are established by defining a grid for the region. The grid is divided into a plurality of cells having a predetermined size. A plurality of static nodes can be placed in the cells. A network identifier that is associated with a standard protocol for the network is assigned to each of the static nodes. The identifier is assigned so as to identify the node and to represent a set of X, Y coordinates associated the cell where static node is located. The X,Y coordinate are assigned to the identifier without deviating from the standard protocol. The identifier is periodically broadcast from the static nodes. A cell of the grid within which a mobile node is located is estimated based on the identifier and an additional parameter received from one of the static nodes. | 10-28-2010 |
20110170005 | AUTOMATIC SWITCHING BETWEEN SIMULCAST VIDEO SIGNALS IN A MOBILE MEDIA DEVICE - A mobile media device may preemptively switch from a terrestrial video signal of a simulcast to a mobile video signal of the same simulcast upon detecting displacement motion. In one example, an apparatus includes a display configured to display video data, and a signal selection unit configured to determine whether the apparatus is moving, wherein the signal selection unit is configured to cause the display to display video data from a terrestrial signal of a simulcast broadcast when the apparatus does not detect displacement motion, and wherein the signal selection unit is configured to cause the display to display video data from a mobile signal of the simulcast broadcast when the signal selection unit detects displacement motion. In this manner, the apparatus may avoid loss of data from the terrestrial video signal that may be caused while moving. | 07-14-2011 |
20110260858 | HYBRID TRACKING DEVICE - Apparatus and methods for tracking various assets. The apparatus includes a hybrid tracking device (HTD) for tracking an associated asset. The HTD includes a personal area network (PAN) transceiver to couple the HTD to a gateway, proxy or slave HTDs. The HTD may include a sensor to generate sensor information. Alternatively, the sensor information is generated remotely. The sensor information includes a determined location and/or information characteristic of an HTD or its environment. Sensor information from one sensor is used to represent HTDs separated by the PAN. The HTD may also include a wide area network (WAN) transceiver to communicate with an asset tracking server. | 10-27-2011 |
20110280167 | WIRELESS PERSONAL AREA NETWORK COORDINATOR - Systems and methods for saving power by a personal area network (PAN) coordinator are described herein. A PAN coordinator is provided to form a wireless PAN with one or more devices. Further, the PAN coordinator enters a sleep state to save power. The wireless PAN is available when the PAN coordinator enters an active state. | 11-17-2011 |
20140254446 | WIRELESS PERSONAL AREA NETWORK DEVICE - Systems and methods for saving power by a personal area network (PAN) coordinator and a device are described herein. A PAN coordinator is provided to form a wireless PAN with one or more of the devices. Further, the PAN coordinator and the devices enter sleep states to save power. The wireless PAN is available when the PAN coordinator enters an active state. | 09-11-2014 |
