Abstract: A method and system including a monitoring device to detect, during a session, a set of radar signals associated with first respiratory-related movements of a first person and second respiratory-related movements of a second person located within a detection zone comprising at least a portion of a bed. The method and system dynamically generate an out-of-bed zone adjacent to a side of the bed. The out-of-bed zone is monitored to detect motion within the zone to determine when the first person exits and enters the bed. The method and system identify a portion of the set of radar signals collected during a time period when the first person is determined to be out of the bed. The identified portion of the set of radar signals is removed from the set of radar signals collected during the sleep session.

Abstract: Systems and methods for fall detection on uneven surfaces utilizing radar are disclosed. For example, an electronic device may receive reflected energy from surfaces in an environment. Corresponding sensor data associated with an object moving on an uneven surface may be utilized to determine a velocity of the object and a height change of the object. When the velocity indicates that the object has stopped moving toward or away from the sensing device, and the height values indicate a sudden decrease in height, a fall event may be detected.

Abstract: Systems and methods for boundary approximation utilizing radar are disclosed. For example, a heatmap of an environment may be generated utilizing data from reflected energy received at a device. The heatmap may be utilized to generate a point cloud representing the environment, where points of the point cloud indicate rates of change of energy intensity associated with surfaces in the environment. The points may be utilized to determine a mean line indicating an approximated distance between a portion of the environment, such as a wall, and the device.

Abstract: A hangable display package that contains a portion of a hand tool in a manner that reveals the hand tool while still contained in the package hanging on a display hook. An outer skin having a front panel, a back panel, and a side panel covers a filler material having a thickness equivalent to the thickness of the tool contained in the display. The front panel and filler are cut to create a cavity that conforms to the size and shape of a part of the hand tool. The front panel has a clear plastic window over the cavity, allowing display of the tool. The tool is held in the display package by the forces exerted on the tool by the filler material and the front and back panels when inserted into the cavity of the display package.

Abstract: A method and apparatus for converting bar code information into a circular barcode from a linear format using a graphics generator are disclosed. Data representative of a user selected barcode are retrieved from storage along with stored character generator data defining a plurality of bars and spaces representative of the user-selected barcode. The retrieved barcode is transformed into a circular barcode for commanding a printer to cause a print of said circular barcode to be made.
