    摘要: Methods, apparatus, systems and articles of manufacture are disclosed to facilitate proximity detection and location tracking. An example method includes receiving messages collected by a badge in an environment, the messages including signal strength and a timestamp. The example method also includes assigning a location in the environment to the badge based on a first subset of the messages. The example method also includes identifying an asset in a second subset of the messages. The example method also includes updating a current location associated with the asset based on a relative proximity of the asset to the badge, wherein the current location corresponds to a first time and the updated location corresponds to a second time, and wherein a change in location between the current location and the updated location indicates movement of the asset in the environment.

    摘要: The relative positions of two or more electronic devices can be determined utilizing ultrasonic beacons. Each device can have a unique signature that can be included in the beacon broadcast by that device. A device having an array of ultrasonic detectors can receive a beacon and correlate the beacon received at each detector. The time of arrival then can be used to determine the relative position of the source of the beacon. The signature in that beacon can also be used to determine the identity of the device that broadcast the beacon, in order to determine the identity of the device, or a user of that device, at the determined relative position. The devices can be configured to transmit signals over the air or through a specific transmission medium, such as propagating surface. Further, a dedicated detector array can be used for determining multiple relative positions.

    摘要: A method is described of using the mobile device so as to control the drain of power from the power source of the mobile device, the mobile device having at least two location determination techniques having respective power drain characteristics, the method includes selecting the location determination technique having a lower power drain characteristic the greater the determined distance of the mobile device from a predetermined location or area, and selecting the location determination technique having the greater power drain characteristic the smaller the determined distance of the mobile device from a predetermined location or area. The method thus uses the least accurate technique when furthest away and the most accurate technique when closer to a predetermined location or area.

    摘要: A radio communication device applies a beamforming pattern defining plurality of beams (411, 412, 413, 414, 415, 416, 417). From the plurality of beams (411, 412, 413, 414, 415, 416, 417), the radio communication device selects at least one main beam (412) and a set of auxiliary beams (411, 413). Exclusively on the at least one main beam (412), the radio communication device sends radio transmissions to a further radio communication device (420). Further, the radio communication device monitors signals transmitted by the further communication device (420) on the at least one main beam (412) and the set of auxiliary beams (411, 413). Depending on the monitored signals, the communication device reselects at least one beam from the set of auxiliary beams as the at least one main beam.

    摘要: A system for automatically ascertaining the location of wireless functional devices, such as lights and switches, in a building. Information from the devices is generated by receipt of electromagnetic signals from other devices, to calculate a best fit for the relative location of the devices in relation to each other. Preferably a map of the building is adduced to refine the location process, for instance by tying the location of a light switch to a wall or a light to a ceiling. The information is used to ascertain that, for example, two devices are in the same room and can be associated with each other. Account can be taken of variable features of the building such as partition walls, to update device settings. There is thus no need to survey the building manually.
