  • Patent number: 11333750
    Abstract: A method and system for determining a position of a non-cooperative object using a reflected signal from Secondary Surveillance Radar (SSR) system is disclosed. The method enables the ownship to detect a non-cooperative intruder, an aircraft which does not have a functioning transponder. The position and altitude of the non-cooperative intruder are determined from reflected signals by a phased array antenna or mechanically scanned directional antenna (MSDA) to perform tracking and avoidance of the non-cooperative object. In the case that a phased array antenna or MSDA is not available, a co-altitude assumption is applied to conservatively determine an avoidance area around the non-cooperative object, which defines coordinates to be tracked and avoided by the ownship.

Then the discretized observation data is resampled by using singular value decomposition, and Akaike information criterion is used to estimate the number of scattering points in the resampled observation data. The obtained number of the scattering points is used to eliminate the singular values in the reconstructed signal. Finally, the sparsity of the observation data is used together with compression sensing to realize signal reconstruction, thereby extracting the height and deformation rate at a position on the high voltage transmission tower.

  • Patent number: 10589747
    Abstract: A method for determining an incline of a road on which a vehicle is located includes importing image data of an environment of the vehicle, the image data being generated by an image sensor. The method further includes identifying a defined reference object in the environment of the vehicle from the image data and identifying a relationship between the identified reference object and a defined reference system of the image sensor. The method also includes estimating the incline of the road on the basis of the identified relationship and providing a signal representing the incline of the road.

  • Patent number: 10579150
    Abstract: A gesture detection system uses two radar tones to concurrently detect absolute distance and relative movement of a target object. A radar-based detection device alternates transmitting a first radar tone and a second radar tone via a radar-emitting device, and then captures a first return signal and a second return signal that are generated by the first radar tone and second radar tone reflecting off the target object. The radar-based detection device demodulates the return signals into a first set of quadrature signals and a second set of quadrature signals and, in some cases, generates a first set of digital samples and second set of digital samples from the respective quadrature signals. Various aspects process the first set of digital samples and second set of digital samples to concurrently identify absolute distance and relative movement and, at times, determine an in-the-air gesture performed by the target object.

  • Patent number: 10573107
    Abstract: A method is provided for authenticating a transceiver in a keyless entry system for a vehicle. The method uses a collision avoidance radar system on the vehicle for authenticating a key fob radar transceiver. A lower power radar signal is transmitted from the vehicle. The lower power radar signal is transmitted below an ambient noise level to make the radar signal difficult for an attacker to detect. The key fob transceiver is then authenticated as being a legitimate transceiver for accessing the vehicle using the low power radar signal. A distance bounding scheme may be used to determine if the key fob is within a predetermined distance. Challenge/response communications may be used to authenticate that the key fob is the legitimate key fob.

  • Patent number: 10566845
    Abstract: Techniques for automated clock synchronization and control are discussed herein. For example, the techniques can include monitoring of transmissions for ‘known’ events and identifying timing or frequencies of such events. Deviations in the timing or frequencies of the events from expected times or frequencies may indicate that wireless power transmission system and receiver clocks are not synchronized. The deviations can be used to synchronize the clock for optimum wireless power transfer. Techniques are also described for enhancing clock control mechanisms to provide additional means for managing the adjustments of the clocks, as well as for enabling wireless power transmission systems to mimic client clock offsets for effective synchronization of events (e.g., beacon signals).

  • Patent number: 10481251
    Abstract: There is provided a radar device that calculates an angle of a target based on a phase difference between reception signals obtained by receiving reflected waves from the target. A transmitting unit alternately transmits first and second transmission waves having different beam patterns. A calculating unit calculates reception levels of the reception signals, and an estimate angle at which the target is estimated to exist. A first determining unit determines a degree of reliability of a level difference between the reception levels, on the basis of a comparison between the level difference with a reference value which is associated with the estimate angle in advance. A second determining unit determines whether the target exists at the estimate angle, on the basis of a determination result and the reception level based on the first transmission wave.

    Abstract: A method, system and computer program product are disclosed for providing a measure of pedestrian congestion in a given area. In one embodiment, the method comprises collecting data from a pedestrian moving in the area, and using the data to determine one or more specified parameters representing a pattern of movement of the pedestrian in the area. These specified parameters are used to determine a sinuosity of pedestrian traffic in the given area. In one embodiment, the pattern of movement is a walking pattern of the pedestrian, and the data collected from the pedestrian identifies a multitude of positions of the pedestrian's feet. In an embodiment, the specified parameters include a lateral gap between the feet of the pedestrian, and a length of a stride of the pedestrian. A sequence of values may be collected for each of these parameters.
