  • Patent number: 11395105
    Abstract: UE location determined by collecting and preprocessing signal data at a detector and sending extracted data to a remote locate server. The detector buffers samples from signals provided by receive channels, detects known reference signals from receive channels based on reference signal parameters, isolates symbols carrying the reference signal from frames, extracts data from symbols, and sends extracted data to locate server. The locate server receives the extracted data, estimates locate observables based on the extracted data and calculates the UE location based on the estimated locate observables, the reference signal parameters and the extracted data. The detector and/or the server may also generate correlation coefficients between reference signals carrying spectrum received from a serving cell and utilize the correlation coefficients to cancel a serving cell signal in symbols that include known in advance reference signals from the serving cell and one or more neighboring cells of the wireless system.

    Abstract: A real-time location system (RTLS) having tags, bridges, bay-level event sensors and a location engine for use in determining the bay location of tags, To determine which bay a tag is in, bay-level event sensors sense motion events in the bay, transmit the motion event reports to a location engine, and/or tags. Tags contain an accelerometer, to sense motion of the tags. A series of location-engine steps estimates the bay-level-location of the tags based on a combination of received signal-strength analysis, and a comparison of tag-motion status to the perceived motion events in a bay. The analysis of tag-motion status and motion-in-bay events produces a better estimate of bay-level location of the tag than a received-signal-strength estimate can produce alone.

  • Patent number: 10218399
    Abstract: Systems and related methods providing for determining activities of individuals are discussed herein. Circuitry may be configured to wirelessly receive tag signals from a plurality of RF location tags. Two or more of the RF location tags may be positioned on an individual, such as at positions that may at least partially define a human frame. The circuitry may be configured to correlate the two or more RF location tags with the individual. Location data for each of the two or more RF location tags may be determined based on the received tag signals. An activity of the individual may be determined based on the location data. In some embodiments, one or more activities involving multiple individuals may be determined based on RF location tags and sensors positioned on each of the multiple individuals. Furthermore, sensor data from the sensors may be communicated over the UWB channel.

  • Patent number: 10162177
    Abstract: A method and apparatus for self-relative body tracking in virtual reality systems using magnetic tracking is disclosed, which allows more accurate tracking of a user's body relative to the user's field of vision. A head-mounted magnetic tracking (HMMT) system is used, in which other parts of a user's body are tracked relative to the HMD on the user's head, rather than relative to a base station. This results in less distortion of the magnetic field used for tracking and thus allows for more accurate determination of the position and orientation of a user's body parts relative to the user's field of vision, so that a more accurate avatar may be presented on the HMD to the user. This allows the avatar of the user's body part to be shown in a location that corresponds closely to its physical position. In an alternative embodiment, multiple portions of the user's body may be tracked.

  • Patent number: 10095306
    Abstract: A wearable device worn on the head of a user determines the head orientation of the user. A tracking application executing on the wearable device determines the orientation of the wearable device relative to a frame of reference. A mobile application executing on a mobile device likewise determines the orientation of the mobile device relative to the frame of reference. The frame of reference may be magnetic north or an inertial reference frame shared between the wearable device and the mobile device. The tracking application estimates the head orientation of the user, relative to the mobile device, based on the relative orientations of the wearable device and the mobile device.

  • Patent number: 9955304
    Abstract: A server has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to collect scan lists from client devices, where each scan list specifies a Wi-Fi access point identifier collected by a client device and geographic coordinates of the client device when the Wi-Fi access point identifier was collected. A cluster of geographic coordinates around a designated Wi-Fi access point is formed. A centroid within the cluster is identified. The location of the centroid is ascribed the geographic position of the designated Wi-Fi access point. The geographic position of the designated Wi-Fi access point is added to a Wi-Fi access point location database. A Wi-Fi tag scan list is processed to form a tag path listing known geographic locations of Wi-Fi access points observed by the Wi-Fi tag. The tag path is supplied in response to a request.
