  • Patent number: 11366216
    Abstract: Systems and methods of measuring distance between two wireless devices by combining phase shift and time-of-flight measurements. A first wireless devices sends a first packet to the second wireless device. After receiving the first packet, the second wireless device sending to the first wireless device a second packet. After sending the second packet, the second wireless device sends a first continuous wave signal to the first wireless device. After receiving the first continuous wave signal, the first wireless device sends to the second wireless device a second continuous wave signal. The first wireless device then calculates a time-of-flight measurement based on a time between the first wireless device sending the first packet and receiving the second packet, and calculates a second measurement based on a phase shift of the first continuous wave signal and the second continuous wave signal, and combines the two measurements.

    Abstract: A technique for controlling objects includes a handheld controller that provides output for generating a virtual ray. The virtual ray has a location and a direction. The location of the virtual ray is measured as a location of the handheld controller, based on input from sensors in the surrounding space. As a user moves and/or rotates the handheld controller, the virtual ray sweeps through space, intersecting various objects. When the virtual ray intersects with the location of a controllable object whose identity and location are known, the handheld controller identifies the object and accepts remote-control input from the user for controlling that object. Using the handheld controller, the user may control any controllable object having a known identity and location in space, and may control virtual as well as physical objects.

  • Patent number: 10966060
    Abstract: A method of determining a location, using bilateration, of an electronic device that is spaced from transmitting devices is disclosed. The electronic device receives first and second signals of the same or different signal type from first and second transmitting devices, respectively, with an antenna. The electronic device determines a signal quality of each signal based on: 1) a received signal strength indicator (RSSI) or a received signal power and a received signal gain, and 2) signal propagation characteristics specific for the transmitting devices. The signals with the two highest signal qualities are used for location determination. The distance from the transmitting devices can be determined based on one or more of: a received signal power and signal gain for both signals, a transmitted power and signal gain of both signals, or location information associated with the transmitting devices.

  • Patent number: 10958301
    Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for synchronizing playback of audiovisual content with a dumb speaker. In some embodiments, a display device transmits a spread spectrum signal to a dumb speaker over a data channel using a spread spectrum code. The display device then receives the spread spectrum signal from the dumb speaker over an audio data channel. The display device despreads the spread spectrum signal based on the spreading code. The display device determines a time of receipt of the spread spectrum signal. The display device calculates an audiovisual output path delay for the dumb speaker based on the time of receipt and a time of transmission. The display device then synchronizes the playback of the audiovisual content at the dumb speaker and a smart speaker based on the audiovisual output path delay.

  • Patent number: 10935625
    Abstract: Methods and systems are described for determining the shortest RF path in a multi-path environment. In an aspect a signal is transmitted by a transmitter. Multiple copies of the signal are received by a multi-directional receiver based on antenna elements that have a unique antenna pattern for each copy of the signal and where the copies are phase correlated and time synchronized. The copies are deconstructed into components of the reflected and line-of-sight waves of the transmitted signal. The shortest path is selected from among the reflected and line-of-sight waves using the deconstruction.

  • Patent number: 10921416
    Abstract: Multivariate position estimation can be performed to provide a position estimate of a moving object. The multivariate position estimation approach can employ multiple types of information including time of arrival (or time difference of arrival), angle of arrival, Doppler, and/or prior location information in an iterative process to calculate a location estimate that is highly accurate. In particular, the multivariate position estimation approach can employ the statistical quality of each of these types of information to quickly arrive at a highly accurate position estimate within a 3D coordinate system. The multivariate position estimation approach can be implemented in environments where a single receiver is available as well as in environments where multiple receivers exist.

  • Patent number: 10901065
    Abstract: Systems, methods, and apparatus for location determination of an emitter using frequency-of-arrival (FOA) measured from a single moving platform are disclosed. In one or more embodiments, a disclosed system allows for location determination of stationary, pulsed radio frequency (RF) emitters from a moving platform by using coherent frequency of arrival (CFOA) Doppler history measurements. The term “coherent” is used to indicate that the process requires a RF-coherent pulse train, such as that generated by modern radar. In one or more embodiments, the disclosed system employs one of two disclosed CFOA measurement methods (Method 1: CFOA linear regression of phase (LRP), and Method 2: CFOA cross-correlated frequency spectra (CCFS)). The disclosed system also enables geo-discrimination (GeoD) of emitters at known locations, or alternatively geo-location of emitters at unknown locations.

  • Patent number: 10902025
    Abstract: In one example embodiment, an analysis application implements a technique for measuring a property of interest of an input dataset of location samples. The analysis application may process the input dataset in one or more multi-stage pipelines to produce values that measure a metric for the input dataset. The values that measure the metric for the input dataset may be compared with values that measure the metric for one or more labeled datasets that are generated by the analysis application, for example, using a feedback loop and sampling from a plurality of delta data sets. Each labeled datasets may have different values that measure the metric and corresponding measures of the property of interest. Based on the comparison, the analysis application may determine the measure of the property of interest for the input dataset and such measure may be returned, for example, to a remote device.

  • Patent number: 10873830
    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.
