Abstract: Various devices, systems and methods for performing contactless monitoring of the sleep of multiple users over a same time period are presented herein. A determination may be made that two users are present within the region. In response to determining that two users are present, a first portion of the data may be mapped to a first user and a second portion of the data may be mapped to a second user. Separate sleep analyses are performed for the first user and the second user.

Abstract: Various arrangements for performing fall detection are presented. A smart-home device (110, 201), comprising a monolithic radar integrated circuit (205), may transmit radar waves. Based on reflected radar waves, raw waveform data may be created. The raw waveform data may be processed to determine that a fall by a person (101) has occurred. Speech may then be output announcing that the fall has been detected via the speaker (217) of the smart home device (110, 201).

Abstract: Systems and methods for mitigating interference in Frequency-Modulated Continuous-Wave (FMCW) radars using an Autoregressive Moving Average (ARMA) model are described. In an illustrative, non-limiting embodiment, a device includes a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the device to: receive a first frame captured by a radar; receive a second frame, captured after the first frame, by the radar; and reconstruct zeroed samples in the second frame with information obtained from the first frame to mitigate interference in the second frame caused by another radar.

Abstract: The present invention includes systems and methods for a continuous-wave (CW) radar system for detecting, geolocating, identifying, discriminating between, and mapping ferrous and non-ferrous metals in brackish and saltwater environments. The radar system (e.g., the CW radar system) generates multiple extremely low frequency (ELF) electromagnetic waves simultaneously and uses said waves to detect, locate, and classify objects of interest. These objects include all types of ferrous and non-ferrous metals, as well as changing material boundary layers (e.g., soil to water, sand to mud, rock to organic materials, water to air, etc.). The radar system (e.g., the CW radar system) is operable to detect objects of interest in near real time.

Abstract: An instrument landing system (ILS) is described. The ILS comprises a plurality of antennas and a plurality of antenna radio units (ARUs). Each ARU of the plurality of ARUs operates to generate a modulated RF signal provided to a different one of the plurality of antennas for transmission. The ILS further comprises a central processing unit that operates to control the ARUs to adjust synchronization between the modulated RF signal provided by the ARUs to the plurality of antennas for transmission.

Abstract: A system and method to perform target detection includes transmitting frequency modulated continuous wave (FMCW) pulses as chirps from a radar system. The method also includes receiving reflections resulting from the chirps, and processing the reflections to obtain a range-chirp map for each beam associated with the transmitting. Curve detection is performed on the range-chirp map for each beam, and one or more targets is detected based on the curve detection.

Abstract: A radar system has different modes of operation. In one mode, the radar operates as a single-input, multiple output (SIMO) radar system utilizing one transmitted signal from one antenna at a time. Codes with known excellent autocorrelation properties are utilized in this mode. At each receiver the response after correlating with various possible transmitted signals is measured in order to estimate the interference that each transmitter will represent at each receiver. The estimated effect of the interference from one transmitter to a receiver that correlates with a different code is used to mitigate the interference. In another mode, the radar operates as a multi-input, multiple-output (MIMO) radar system utilizing all the antennas at a time. Interference cancellation of the nonideal cross-correlation sidelobes when transmitting in the MIMO mode are employed to remove ghost targets due to unwanted sidelobes.

Abstract: The present disclosure relates to a non-contact power closure member system for operating a liftgate of vehicle. The non-contact power closure member system includes at least one sensor for sensing an object or motion when a key fob is located within a predetermined distance of the vehicle. An indicator is located on the vehicle to inform the user of the appropriate location to make an activation gesture. The system also includes an electronic control unit connected to the at least one sensor and executing software. The electronic control unit processes the data to determine if the gesture made by the user is the activation gesture required to open the liftgate, or a false signal. In response to the activation gesture, the electronic control unit initiates opening of the liftgate. Methods are provided for operating the liftgate of a vehicle using a non-contact power closure member system.
