  • Patent number: 11061111
    Abstract: The present disclosure relates to a signal processing apparatus, a signal processing method, and an object detection system. A stereo camera performs imaging by a right camera and a left camera to acquire a stereo image and a millimeter wave radar acquires a radar image in which a position of an object is detected in a radiation range of millimeter waves by using millimeter waves. Then, by communication via a communication apparatus with a target in which positional information is known, it is determined whether or not the target is reliable, and in a case where it is determined that the target is reliable, calibration processing is performed for eliminating a deviation in coordinate systems generated in the stereo image and the radar image in which the target is detected.

  • Patent number: 10516278
    Abstract: A measurement circuit measures a first integrated amount (integrated current amount) of a current which flows from a battery to a load. The first integrated amount is an amount in a first time period in which the measurement circuit operates. A detection circuit detects the number of operations of the load. A calculation circuit calculates a second integrated amount (total integrated-current amount) of the current on the basis of the number of operations and the first integrated amount. The second integrated amount is an amount in a third time period including a second time period in which the measurement circuit stops.

  • Patent number: 10511465
    Abstract: The present technology relates to a transmitter, a transmission method, a receiver, and a reception method that can keep upsizing and cost increase to a minimum. The transmitter and the receiver have a detection mode and a communication mode as operation modes. The detection mode detects contact between a first waveguide on the side of the transmitter and a second waveguide on the side of the receiver. The communication mode sends or receives a modulated signal, acquired through frequency conversion of a baseband signal, via the first and second waveguides. The transmitter sends a given signal to the first waveguide in the detection mode. The transmitter and the receiver go from the detection mode to the communication mode in response to a given signal received by the receiver via the second waveguide and send and receive the modulated signal via the first and second waveguides in the communication mode.
