摘要： In an imaging apparatus, a common region identifier identifies a common region of each of a first image captured by a front monitor camera and a second image captured by a surrounding monitor camera. A difference calculator calculates a target luminance difference between the common region of the first image and the common region of the second image. A luminance adjuster performs, based on the target luminance difference, at least one of (i) a first adjustment of adjusting a luminance of the first image and (ii) a second adjustment of adjusting the at least one imaging parameter of the front monitor camera.

摘要： A reverse connection protection relay of a power supply device is provided in a power supply line between a battery and an input capacitor and is parallel connected with a diode that allows current flow from a battery side to a power converter side, and interrupts the current flow from the power converter side to the battery side when the protection relay is turned off. At a time of initial check, a booster circuit performs an overboost process in which a target voltage is temporarily raised above a value during normal operation. A precharge circuit applies a boosted voltage to an electrode on a high potential side of the input capacitor. A monitoring circuit detects an abnormal due to being stuck in an ON state or in an OFF state of the protection relay according to a post-relay voltage that is a voltage on the inverter side of the protection relay.

摘要： A control unit includes multiple controllers, an intersystem communication circuit, an internal power supply circuit and a protection circuit. The controllers control a load, and are connected to individual circuit arrangements. The individual circuit arrangements are defined as systems. The intersystem communication circuit is connected between one of the systems and remainder of the systems. The internal power supply circuit is included in each system. The internal power supply circuit supplies electric power to corresponding one of the controllers and the intersystem communication circuit. The protection circuit cuts off an internal power supply line between the internal power supply circuit and the intersystem communication circuit or limits supply of the electric power to the intersystem communication circuit, in response to the occurrence of an overvoltage abnormality in which an output voltage of the internal power supply circuit is in an overvoltage state.

摘要： An analog-to-digital converter includes an input-signal chopping switch, an integrator, an output chopping switch, a quantizer, and a feedback switch. The integrator is located after the input-signal chopping switch. The integrator includes an operational amplifier, an integral capacitor, and an integral-capacitor-chopping input switch being at on an input side of the integral capacitor. The output chopping switch is on an output side of the operational amplifier. The quantizer is located after the output chopping switch. The feedback chopping switch is in a feedback path from an output of the quantizer to an input of the first integrator. The input-signal chopping switch, the integral-capacitor-chopping input switch, the output chopping switch, and the feedback chopping switch execute chopping at an identical frequency. The output chopping switch sets a polarity of an input value of the quantizer to be identical before and after the chopping.

摘要： A motor device includes a motor housing, a stator, an electric power lead-out wire, and a first rotor. The motor housing accommodates the stator and the first rotor. The stator includes a coil portion. The electric power lead-out wire is led out from the coil portion. The electric power lead-out wire includes a rising avoidance portion. The rising avoidance portion extends in an axial direction passing between the first rotor and a motor inner peripheral surface. The rising avoidance portion is flat such that a thickness dimension in a radial direction is smaller than a width dimension in a circumferential direction. In the rising avoidance portion, an avoidance outer surface faces the motor inner peripheral surface.

摘要： A motor device includes a motor housing, a stator coil, and a temperature sensor. The motor housing accommodates the stator coil and the temperature sensor. In the motor housing, motor fins are provided on a motor outer peripheral surface. The motor fins are provided on a radially outer side of the stator coil. The temperature sensor is provided on a radially inner side of the stator coil. In the motor device, heat radiation of the stator coil toward the radially outer side is accelerated by the motor fins such that heat radiated from the stator coil toward the radially outer side is more than heat radiated from the stator coil toward the radially inner side.

摘要： A motor device includes a motor housing, an electric power lead-out wire, a grommet, and a first rotor. The electric power lead-out wire is led out from a coil and is electrically connected to an electric power busbar. The electric power lead-out wire includes an outer peripheral lead-out portion and an intersection lead-out portion. The outer peripheral lead-out portion is provided on an outer peripheral side of the first rotor and extends along an inner peripheral surface in an axial direction. The intersection lead-out portion extends in a direction intersecting the outer peripheral lead-out portion. The grommet includes an outer grommet portion and an inner grommet portion. The outer grommet portion enters between the outer peripheral lead-out portion and the inner peripheral surface in a radial direction, and extends further toward the electric power busbar than the outer peripheral lead-out portion in the axial direction.
