    Abstract: The invention is related to a pair-assignment device (100) comprising a sensing-node position ascertainment unit (102) configured to ascertain position information (P.I.) pertaining to respective positions of external RF-sensing nodes (104,106) with respect to a predefined sensing volume (108) of a RF context-sensing arrangement and a pair-assigning unit (110) configured to assign, using the ascertained position information, at least one transmitter-receiver pair among the individual RF-sensing nodes of the RF context-sensing arrangement to perform a RF context-sensing function, to assign to the RF sensing nodes of the given transmitter-receiver pair a transmitter role (Tx) and a receiver role (Rx), respectively. The pair-assignment device then provides pair information indicative of the at least one assigned transmitter-receiver pair and the assigned transmitter and receiver roles and thus enables an increase of tolerance of the RF context-sensing arrangement against changes in the position of movable objects.

    Abstract: A target detecting apparatus based on radar includes a radar sensor that radiates radar signals in different directions of a vehicle to detect a target, and a controller that generates an initial track based on target detection information from the radar sensor, and compares first detection sensor information obtained by detecting the initial track and second detection sensor information, in which a location coordinate of the initial track is included in a detection area, to determine whether the initial track is a false target.

    Abstract: A system and method is disclosed for determining a particular vehicle state based on a UWB signal received at a plurality of receiving nodes. A plurality of channel-impulse responses (CIRs) may be computed from the UWB signal received from the plurality of receiving nodes. A plurality of peak-based features based on a selected position and amplitude may be extracted from the plurality of CIRs. A plurality of correlation-based features may be generated by correlating the plurality of CIRs to a corpus of reference CIRs relating to a plurality of vehicle states. A plurality of maximum likelihood vehicle matrices may be generated by correlating the plurality of CIRs to the corpus of reference CIRs relating to the plurality of vehicle states. The vehicle state may then be determined by processing the plurality of peak-based features and correlation-based features using the machine learning classification algorithm.

    Abstract: Aspects described herein include methods and devices for radar integration with a mmW communication module. In some aspects, an apparatus is provided that includes a millimeter wave (mmW) printed circuit board (PCB), with first and second mmW elements, and a radar antenna. The first mmW element is coupled to a first side of the mmW PCB, where the first mmW element is configured for wireless mmW communications at frequencies above approximately 24 gigahertz (GHz). A second mmW element coupled to the first side of the mmW PCB, where the second mmW element is positioned adjacent to the first mmW element and is separated from the first mmW element by a gap spacing. A radar antenna is disposed in the mmW PCB and aligned with the gap spacing between the first mmW element and the second mmW element.

    Abstract: Embodiments of the disclosure describe systems and methods for monitoring occupancy in a room. The method comprises causing, via a detection unit, transmission of radar signals within the room over a predefined period of time. The method further comprises receiving, via the detection unit, reflected signals corresponding to the transmitted radar signals, the reflected signals being indicative of information associated with the room. The method further comprises determining, based on the reflected signals, presence of one or more occupants within the room. The method further comprises, in response to determining presence of the one or more occupants within the room, determining one or more of: an activity associated with the one or more occupants within the room, preferences associated with usage of the room by the one or more occupants within the room, and a visualization map associated with the room.

    Abstract: A control device for a ceiling fan may have a motor drive circuit configured to control a rotational speed of a motor of the ceiling fan, an occupancy sensing circuit, and a control circuit configured to adjust the rotational speed of the motor in response to a detected occupancy or vacancy condition. The control circuit may process the signals generated by the occupancy sensing circuit to eliminate the effects of vibrations and/or wobbling of the ceiling fan. The control circuit may control the motor drive circuit to adjust the rotational speed of the motor in response to an accelerometer to minimize the magnitude of the wobble of the ceiling fan. The control circuit may be configured to learn a preferred rotational speed for the motor. The control circuit may also be configured to control the rotational speed of the motor to affect a thermal comfort level of an occupant.
