摘要： This disclosure describes, in part, techniques for generating location information associated with a video. For instance, an electronic device may use a radar sensor to generate radar data. The electronic device may then analyze the radar data in order to determine a location associated with an object. In some instances, the location may correspond to at least a first coordinate along a first axis and a second coordinate along a second axis. The electronic device may also generate image data using the imaging device. Additionally, the electronic device may analyze the image data in order to determine that the image data represents an object and/or a type of object. The electronic device may then generate location data representing an identifier for the object and the location. Next, the electronic device may send the image data and the location data to one or more computing devices.

摘要： A Doppler motion sensor device is used for detecting a motion of an object. The Doppler motion sensor device includes a first antenna and a second antenna. The first antenna is used to transmit or receive a first wireless signal. The second antenna is used to transmit or receive a second wireless signal. A first straight line passing through a first feed-in point and a first middle point of the first antenna is orthogonal to a second straight line passing through a second feed-in point and a second middle point of the second antenna. One of the first wireless signal and the second wireless signal is a transmission signal. The transmission signal is reflected by the object to form the other one of the first wireless signal and the second wireless signal.

摘要： A mobile device may receive a plurality of timestamps, wherein the plurality of timestamps indicate sending and receiving time for ranging packets and response packets. The mobile device may calculate a responder turn-around time as a first difference between the second time and the first time. The mobile device may calculate a responding round trip time as a second difference between the second time and the third time. The mobile device may receive from the electronic device an initiator turn-around time and an initiator round trip time. The mobile device may calculate a frequency offset for the wireless protocol using the responder turn-around time, the responding round trip time, the initiator turn-around time, and the initiator round trip time. The mobile device may compare an observed frequency offset to the calculated frequency offset to determine a frequency offset difference and whether it exceeds a threshold, adjusting a ranging measurement.

摘要： A measurement apparatus repeatedly executes measurement determination of whether measurement of a wall object has succeeded. If the wall-object measurement has succeeded, the measurement apparatus calculates an instantaneous wall-distance value indicative of a distance of the wall object from the own object. Otherwise, if the wall-object measurement has not succeeded, the measurement apparatus executes first extrapolation of an additional instantaneous wall-distance value. The measurement apparatus prevents an additional execution of the first extrapolation upon determination that the frequency of continuously repeated executions of the first extrapolation is not less than a prevention threshold frequency. The measurement apparatus sets, if the result of the measurement determination is correct, a correct-state threshold as the prevention threshold frequency, and sets, if the result of the measurement determination is incorrect, an incorrect-state threshold as the prevention threshold frequency; the incorrect-state threshold is smaller than the correct-state threshold.

摘要： Methods for determining a location of an object using radio measurement observations in a radio network. An example method comprises the step of obtaining (1610) information comprising (a) a first angle-of-arrival parameter and/or first angle-of-departure parameter corresponding to a non-primary propagation path of a radio signal transmitted between a first wireless device and a second wireless device, and further comprising either or both of (b) a delay measurement or time-of-arrival measurement for the non-primary propagation path: and (c) a second angle-of-arrival parameter and/or second angle-of-departure parameter corresponding to the non-primary propagation path, the second angle-of-arrival parameter and second angle-of-departure parameter corresponding to a different end of the non-primary propagation path to the first angle-of-arrival parameter and angle-of-departure parameter. The method further comprises estimating (1620) a location for an object other than the first and second wireless devices, based on the obtained information.

摘要： A modular, radio frequency (“RF”) system includes one or more directional antennas and is configured with both hardware and software components to enable the RF system to monitor (e.g., detect or track signals or objects) and/or interact with (e.g., track signals or objects, or transmit signals) objects in particular directions. The RF system includes one or more machine learning models to determine, based on received signals, one or more signals to transmit.

摘要： False detection of a ghost is prevented. A radar apparatus includes: transmission circuitry, which, in operation, transmits a radar signal; main reflective object detection circuitry, which, in operation, detects a main reflective object in a detection area using a reflected wave of the radar signal; in-area determination circuitry, which, in operation, determines a main area where a ghost caused by a reflective object outside the detection area and the main reflective object is located, the main area being inside the detection area; and auxiliary reflective object detection circuitry, which, in operation, detects a position of an auxiliary reflective object in the main area using a reception signal of the reflected wave of the radar signal, the auxiliary reflective object being located farther than the main reflective object on an extension of a line connecting the radar apparatus and the main reflective object.
