Abstract: A hitch angle detection system to detect a trailer hitch angle with a simple, versatile configuration is provided. Edge detection is performed in a portion including an image of a rear bumper of a tractor and an image of a front bumper of a trailer, the portion being included in an image captured by a rear camera, to extract an edge of the tractor rear bumper image and an edge of the trailer front bumper image. A straight line with which the edge of the rear bumper image is best approximated is calculated as a straight line parallel with the tractor left-right direction. A straight line with which the edge of the trailer front bumper image is best approximated is calculated as a straight line parallel with the trailer left-right direction. The relative angle of the straight line to the straight line is calculated as the trailer hitch angle.

Abstract: A current sensor includes a busbar extending in a direction, a magnetic sensor facing the busbar in a direction intersecting the direction in which the busbar extends, a magnetic shield having a base that faces the busbar, at least a portion of the base facing a side of the busbar opposite to a side where the magnetic sensor is disposed, and a case having an insert-molded section in which at least a part of the magnetic shield is insert-molded. The insert-molded section has holes (first holes), and in the holes (first holes), some portions of the magnetic shield are exposed as exposure portions (first exposure portions) and the exposure portions (first exposure portions) have rust-prevention properties. Such a current sensor has the rustproofed exposure portions and thus problems caused by rusting in the exposure portions in the magnetic shield can be prevented or reduced.

Abstract: An electrostatic input device includes a capacitance detector that is disposed at an operation part to be operated by a living body, and is configured to detect capacitance; and a controller that is formed of an integrated circuit, and is configured to transition the capacitance detector to an activated state in response to an increment in the capacitance detected by the capacitance detector reaching or exceeding a first predetermined value a predetermined number of times or more within a predetermined period in a case in which the capacitance detector is in a standby state and no contact with the living body is detected.

Abstract: A speaker distortion correction device includes an amplifier configured to drive a speaker; and a distortion corrector. An input signal is input to the distortion corrector, and an output of the distortion corrector is input to the amplifier. The distortion corrector includes a nonlinear distortion controller configured to generate a corrected signal obtained by performing a nonlinear distortion correction process on the input signal so that nonlinear distortion of the speaker is suppressed when the corrected signal is input to the amplifier; a maximum value calculating section configured to calculate a maximum output value of the amplifier to be obtained when the corrected signal is input to the amplifier, based on at least the input signal; and a selector configured to select the corrected signal when the maximum output value does not exceed a predetermined threshold and select the input signal when the maximum output value exceeds the predetermined threshold.
