VAYYAR IMAGING LTD.

Systems and methods for detecting living bodies in vehicles and generating alerts only if a child is detected. A radar detection system uses vehicle vibration, temporal behavior analysis and spatial characteristics modules to detect false positives by analyzing image data over time and space to distinguish between real children and other similar voxel clusters within the radar images.

Systems and methods for tracking targets by a network of radar sensors each monitoring targets in a portion of an extended range. Each radar sensor characterizes and identify the detected targets and communicates metadata with neighboring sensors such that the identified targets may be uniquely identified and continuously tracked as they move between different portions of the extended monitored region. In a retail environment, customer behavior may be monitored with a customer journey generated indicating a path taken by each identified customer.

Systems and methods for detecting angle of a vehicle using a radar including an array of transmitters, transmitting electromagnetic radiation towards surrounding objects, and receivers detecting reflected electromagnetic signals. Received information includes horizontal coordinates and vertical coordinates for each object detected. A pre-processing unit determines stationary and non-stationary state of objects from the received electromagnetic signals. A processing unit receives the coordinates along with motion characteristics of objects and plots each reflected object in the horizontal-vertical plane perpendicular to the direction of motion of the vehicle. A virtual box is constructed corresponding to each of a series of candidate tilt or roll angles. The angle of the virtual box having the largest number of plotted reflections is selected as the angle of the vehicle.

Radar based systems and methods for gesture recognition to identify hand gestures remotely. A radar unit including a linear array of transmitter antennas and a linear array of receiver antennas monitors objects within a target zone. An image data file is generated by assigning each transmitter-receiver pair of antennas a spatial coordinate, an associated phase value and an associated amplitude value. The image data file is analyzed by a pattern recognition unit to detect assign a gesture state.

Systems and methods for a radar-based viral transmission prevention for a protected space are disclosed. The system comprises a gateway screening system 104 configured for remotely screening subjects crossing a boundary of a protected space, an elevator monitoring system 106 configured for monitoring passengers using an elevator system and a social distance monitoring system 108 configured for monitoring social distancing compliance within the protected space. The system also includes a telemedical monitoring system 110 configured and operable for remotely measuring one or more parameters of a patient using a radar-based system. The system further includes a gesture recognition system 112 configured and operable to identify hand gestures remotely.

A system including a radar unit, a processor unit and a communication module, the radar unit including a transmitter antenna connected to an oscillator and transmitting electromagnetic waves into a monitored region, and a receiver antenna receiving electromagnetic waves reflected by objects within the monitored region and generating raw data, the communication module communicating alerts to third parties, the processor unit including a moving body isolation processor, a tracker module receiving and processing data from the radar unit to identify and track location of moving targets over time thereby generating target data, an alert-threshold generator generating an alert-threshold, a neural network receiving from the tracker module target data inputs selected from height profiles, signal-to-noise ratio and radial distance to object and generating a fall likelihood score, and a fall identification module receiving the fall likelihood score and detecting a fall event if the likelihood score is above an alert-threshold value.

Using transmitters and receivers for detecting occupants in a vehicle, and classifying those occupants according to the geometry of the vehicle, where sets of complex values associated with voxels in a predetermined region of the vehicle are converted into 3D complex images, where clusters of voxels in the 3D complex images are analyzed to determine presence of occupants, and where positions of seats may determine which seats in the vehicle are occupied.

Systems and methods for sensing the surroundings of vehicles via vehicle mounted radar sensors. A directional transmitter array transmits radiation into the region surrounding the vehicle and a receiver array receives the radiation reflected back. Controllers may use self-velocity calculation modules, wall detection modules, dynamic range enhancement modules, double reflection detection modules and the like to harvest useful information such as the vehicles relative speed and the identification of hazards in its surroundings.
