摘要： A beacon device is provided in proximity to a computing system within a computing center. A request to locate the computing system in the computing center is triggered on a central control unit. In response to the request to locate the computing system, the control unit generates specification data for a unique radio signal identifier, sends an activation request and the specification data to the beacon device, and provides the specification data to a portable device and stores the specification data on the portable device. In response to receiving the activation request, the beacon device sends a radio signal identifier generated from the specification data.

摘要： Systems and methods for improving bearing availability and accuracy in a traffic collision-avoidance system (TCAS). In an exemplary method, if only a single phase-difference value is received for one of two two-element antennas, a processor determines an expected maximum antenna element phase-difference value for the elements of the two-element antenna that did not receive a phase-difference value for a target signal source; estimates a phase-difference value for the two-element antenna that did not include a phase-difference value, based on the expected maximum antenna element phase-difference value and a previously determined predicted bearing value; and calculates bearing based on the estimated phase-difference value and a phase-difference value received from the other two-element antenna. The determination is based on previously received signals associated with the target signal source and based on elevation information of the target signal source and a predefined maximum antenna element phase-difference value for the respective antenna element pair. An output device outputs information associated with the calculated bearing.

摘要： According to an embodiment of the present invention, geolocations of multiple unknown radio frequency (RF) signal sources are determined using three-dimensional (3-D) geolocation techniques. The three-dimensional (3-D) geolocation techniques obtain reliable geolocation estimates of radio frequency (RF) emitters based on energy or received signal strength (RSS) of emitter transmitted signals and based on their time differences of arrival (TDOAs) at various sensor locations. The energy based geolocations and the time difference of arrival (TDOA) geolocations are combined to determine an overall set of geolocations for multiple unknown radio frequency (RF) signal sources. The geolocation information is used to track and monitor the locations of the multiple emitters.

摘要： A method to support client device position discovery within a building includes ascribing building position coordinates to beacons within the building. The building position coordinates are converted to physical position coordinates. The physical position coordinates are augmented with at least one additional parameter that supports position resolution. A client device communicates with accessed beacons positioned within the building. A beacon location database characterizing the physical locations of the accessed beacons is also accessed. The physical location of the client device is computed based upon the physical locations of the accessed beacons.

摘要： Position location signaling system, apparatus, and method are disclosed. Position location beacons can each be configured to transmit a frequency interlaced subset of orthogonal frequencies spanning substantially an entire channel bandwidth. The orthogonal frequencies can be pseudorandomly or uniformly spaced, and each beacon can be allocated an equal number of orthogonal frequencies. Each frequency of the interlaced subset of orthogonal frequencies can be modulated with an element of a predetermined data sequence. A mobile device can receive one or more of the beacon signals and determine a position using a position location algorithm that determines position in part on an arrival time of the beacon signal. Where the mobile device can receive three or more beacon signals, the mobile device can perform position location by trilateration to the beacon positions based, for example, on a time difference of arrival.
