Abstract: Systems, methods, and computer-readable media are described for compact radar systems. In some examples, a compact radar system can include a first set of transmit antennas, a second set of receive antennas, one or more processors, and at least one computer-readable storage medium storing computer-executable instructions which, when executed by the one or more processors, cause the radar system to coordinate digital beam steering of the first set of transmit antennas and the second set of receive antennas, and coordinate digital beam forming with one or more of the second set of receive antennas to detect one or more objects within a distance of the radar system.

Abstract: The present invention relates to devices and methods that use cooling and/or heating systems in pillows. More specifically, the present disclosure relates to systems that can constantly transport a fluid throughout a pillow in order to keep the fluid at a desired temperature. In order to start the cooling/heating process, a cooling/heating device can use fluid from a tank or reservoir that can be cooled/heated by a radiator. This fluid can then exit the system, be filtered through a hose or line, and then enter the pillow itself. After flowing through the entire pillow, the fluid can be transported out of the pillow and back to the cooling/heating device. By utilizing such a design, the cooling/heating system can keep the fluid moving throughout the pillow and at a desired temperature. As such, the pillow can also maintain a corresponding desired temperature.
