    摘要: An assembly is provided combining a low power light source, a distance measuring radio, an electrical storage and an adapter compatible with an existing socket for a light unit. The unique configuration of the assembly enables deployment of distance measuring radios in buildings, vehicles and outdoor venues without the need to install dedicated infrastructure such as electrical grid connections. A method is further disclosed of automatically determining the location of a newly installed assembly by first learning the locations of already installed neighboring assemblies, measuring the distances to such known assemblies, and using the measured distances to determine the location of the newly installed assembly.

    摘要: A method of determining a new position for a node. The node having a distance measuring radio. A list of positions of a plurality of neighboring nodes is obtained. The geometric relationship of the positions in the list and the predicted position of node is analyzed. A subset of the nodes is selected from the list that is less than the total number of modes in the list. Electronic distance measurements from the node to each of the subset of nodes are performed. A new position of the node is determined utilizing the measured distances.

    摘要: A method of distributing intention signaling messages for a vehicle. The vehicle having a plurality of directional radio antennas oriented to transmit radio signals in predetermined and distinct directions. Responsive to the intended change in the vehicle motion, at least one of a plurality of directional radio antennas is selected. The selected directional radio antenna facing in the direction of surrounding traffic which would be affected by the intended change in motion is selected. An intention signaling message is formed and transmitted. The intention signaling message corresponds to the intended change in the vehicle motion by means of the selected directional radio antenna.

    摘要: A digital map representing a physical location as a hierarchical structure of cells. Each cell has attributes including but not limited to permeability in each direction of a three-dimensional coordinate system and associated with one or more faces or edges of a boundary. The permeability pertains separately to transmissions of radio frequency signals and to physical travel of objects and persons.

    摘要: An electronic beacon placed stationary in a known location. The beacon includes a map, stored therein, pertaining to a covered area. The map includes coordinates of the known location with reference to the map. The electronic beacon is configured to transmit at least a navigational signal. The electronic beacon has a radio transmitter to communicate the map to at least one moving device in the covered area.

    摘要: Methods for geolocation utilizing electronic distance measurement equipment. The methods select a small subset of available data that is most trustworthy, and then mathematically treats the subset of data (preferably bilateration or trilateration) to compute one or more new measured position candidates. One measured position candidate may be chosen among the measure position candidates based on confidence metrics, relative position geometry, and the comparison with history-based predicted position and its respective confidence metric. In a case where no measured position candidates of sufficient confidence are available, the predicted position is taken as the new position.
