  • Publication number: 20180259621
    Abstract: The present disclosure relates to a signal processing apparatus, a signal processing method, a program, and an object detection system that enable an object detection to be accurately performed. A stereo camera performs imaging by a right camera and a left camera to thereby 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 that are radio waves of a millimeter wave band. 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.

  • Publication number: 20180183251
    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: 9536669
    Abstract: In a method of forming a plating layer for an external terminal electrode by applying, for example, copper plating to an end surface of a component main body with respective ends of internal electrodes exposed, and then applying a heat treatment at a temperature of about 1000° C. or more in order to improve the adhesion strength and moisture resistance of the external terminal electrode, the plating layer may be partially melted to decrease the bonding strength of the plating layer. In the step of applying a heat treatment at a temperature of about 1000° C. or more to a component main body with plating layers formed thereon, the average rate of temperature increase from room temperature to the temperature of about 1000° C. or more is set to about 100° C./minute or more. This average rate of temperature increase maintains a moderate eutectic state in the plating layer and ensures a sufficient bonding strength of the plating layer.
