  • Patent number: 11774546
    Abstract: Techniques for determining the position of an endpoint when a signal from the endpoint is received by multiple receive beams are described. According to some embodiments, the ratios of receive beam amplitudes for symbols received from the endpoint are compared to an ideal ratio that assumes no interference. Since the ideal ratio is indexed to the endpoint's position, the position of the endpoint can be estimated by comparing the calculated ratios to the ideal ratio. Endpoint position accuracy is further improved in some embodiments by using multiple spatially separated antenna arrays that jointly beamform. Embodiments described herein advantageously provide as good as, or better than, GPS-level accuracy without requiring an impractically large number of antennas.

  • Patent number: 11733367
    Abstract: The system and method for chromatic correlation interferometry direction finding (CIDF) used to resolve ambiguities. Ambiguities are overcome by correlating over a range of frequencies. In some cases, multiple (i.e., 2 or more) frequencies or a continuous range of frequencies are used to make a more robust correlation manifold. As the complex response manifold is frequency dependent, using a set of two or more manifolds provides a significant reduction of false peaks.

  • Patent number: 11385319
    Abstract: Disclosed is an approach for improving positioning quality via a feedback loop between a radio-based positioning system and a client device, such as a tracking system. In particular, the tracking system or other client device may request and then receive a position estimate from the positioning system. The tracking system could then make a determination that the position estimate is incorrect, such as by determining that it is an outlier relative to a location trace, for instance. Responsive to this determination, the tracking system may transmit, to the position system, an indication of radio node(s) associated with the incorrect position estimate. Based on this indication, the positioning system could then exclude one or more of those radio node(s) from a radio map, thereby improving quality of the radio map and in turn quality of future position estimates, among other advantages.

    Abstract: An example system connects to a location engine in a mesh network, transmits a first message indicating a bus master service hosted by a bus master, and receives a message indicating a location service hosted by a location engine and an aggregation service hosted by an aggregator connected to the location engine. The bus master stores a first entry corresponding to the location service and a second entry corresponding to the aggregation service. The bus master transmits a request to access the location service; receives a response confirming a subscription to the location service; and receives timing data indicating times at which the multiple receivers in a clinical environment received a wireless signal from a tag. The bus master aggregates the timing data into a data stream and transmits data stream to the location service in accordance with the subscription.

  • Patent number: 11218839
    Abstract: A method and a device for zone-based localization of mobile devices are described. In an example, a zone from amongst a plurality of zones of an indoor space in which a mobile device is present is identified. The identification of the can be based on instantaneous localization information obtained from the mobile device. Further, a localization criterion to be employed for localizing the mobile device is determined based on the identified zone. The localization criterion may be indicative of a selectivity in use of sensor data for localizing the mobile device. Subsequently, the mobile device is localized in the indoor space, based on the localization criterion.

  • Patent number: 11181607
    Abstract: In a geolocation system, ancillary parameter values, i.e., those produced during the geolocation process but not directly related to the calculation of the geolocation, are recorded and stored. These “ancillary” parameter values include signal characterization data and secondary measurements produced in the calculation of the geolocation. These parameter values are processed, in one approach, with respect to a weighted matrix in order to determine a confidence or fidelity value of the determined geolocation. Confidence is an indication of the likelihood that the geolocation result produced is in fact the desired target and that the identified location has a reasonable degree of quality so as to be practical or accurate.

  • Patent number: 11175370
    Abstract: Techniques are provided for emitter geolocation. A methodology implementing the techniques according to an embodiment includes measuring phase differences between radar signals received at one or more pairs of antennas. The method also includes calculating hypothesized phase differences based on ray tracings from hypothesized emitter locations at a first set of grid points, to the antennas. The method further includes generating scores based on correlations between the measured phase differences and the hypothesized phase differences. The method further includes generating an error ellipse based on candidate grid points associated with scores that are above a threshold. The process may be repeated on a second set of grid points, bounded by the error ellipse, to generate a second set of scores. The grid point, from the second set of grid points, that is associated with the highest of the second set of scores is selected as the estimated emitter geolocation.

  • Patent number: 11134368
    Abstract: A system for appending an emergency call (e.g., E911) with a location is described herein. The system appends the emergency call to a public safety answering point (PSAP) with a location from which the E911 call occurred. A user equipment (UE), which places the emergency call, connects to the beacon via short-range communication and acquires the location from a beacon. The UE transmits the location to the PSAP via a telecommunications network.

  • Patent number: 11044578
    Abstract: In a general aspect, a method is presented for detecting a location of motion using wireless signals that propagate along two or more paths of a wireless communication channel. The method includes storing a set of eigenvectors derived from first motion-sensing data associated with a first time frame. The first motion-sensing data is associated with a first motion-sensing topology of a wireless mesh network. The method also includes obtaining a motion vector based on wireless signals transmitted between access point nodes in the wireless mesh network during a second, subsequent time frame. The wireless mesh network operates in a second, distinct motion-sensing topology during the second time frame. The motion vector is compared with the respective eigen vectors, and a probability vector is generated based on the comparison. A location of the motion of the object during the second time frame is determined based on the probability vector.

  • Patent number: 11009358
    Abstract: A travel coordination system provides suggestions to providers for where they should go to reduce the wait time between trips. A geographic region is broken down into zones and a score is generated for each zone. A zone score can be generated by determining the estimated wait time for the zone and generating a model for the wait time. A zone score can also be generated using a model for the wait time using factors that likely contribute to the wait time. The zone score for each zone is displayed to the provider on a road map of the geographic region along with the boundaries of each of the zones and the provider's position within the region. The travel coordination system also suggests driving routes. The travel coordination system selects a target zone and generates candidate routes to the zone. A route is selected based on route scores.

    Abstract: A plurality of access points located within a building structure may provide various location-based services, such as navigation, to mobile devices within the building structure. To more accurately determine the location of the plurality of access points, a floorplan of the interior of the building structure may be obtained. A plurality of images of the interior of the building structure is then obtained. At least one of the images includes an image of at least one of the plurality of access points. A plurality of reference points may also be located within the building structure and obtained. Based on the plurality of images, reference points, and the floorplan, a composite image of the interior of the structure is generated. Based on the composite image, the location of each of the plurality of access points is determined.
