摘要： The present invention provides a motor driver and a motor driving system capable of suppressing power consumption when a motor is in a brake state. The motor driver of the present invention includes: a half-bridge power output section, including a high-side transistor and a low-side transistor; a high-side driving circuit, driving the high-side transistor; and a control portion. When switching to a brake mode, the low-side transistor is turned on and the control portion turns off the high-side driving circuit.

摘要： A vehicular windshield wiper control system includes a camera disposed at a vehicle and viewing through a windshield of the vehicle and an electronic control unit (ECU). Electronic circuitry of the ECU includes an image processor. The system, based on processing of image data captured by the camera, is operable to determine presence of a substance at an outer surface of the windshield. The system includes a windshield wiper having a rubber wiping blade and a cleaning element. The system is operable to (i) cause the rubber wiping blade to engage the windshield and/or (ii) cause the cleaning element to engage the windshield. Responsive to determining presence of the substance, the system causes the cleaning element to engage the windshield. With the rubber wiping blade and/or cleaning element engaging the outer surface of the windshield, the system moves the rubber wiping blade and/or cleaning element along the windshield.

摘要： A droplet sensor includes an optical cover that forms part of a spheroid, a major axis of the spheroid being a vertical axis, a light emitting/receiving device disposed at a position offset from a first focal point of the spheroid along the major axis, and a reflector disposed in vicinity of a second focal point of the spheroid. The optical cover has an effective detection area between the light emitting/receiving device and the reflector. The effective detection area satisfies a total internal reflection condition at an interface with a gas, and does not satisfy the total internal reflection condition at an interface with a liquid. The reflector reflects, towards a light receiving surface of the light emitting/receiving device, light totally reflected by the effective detection area, or reflects, towards the effective detection area, light directly incident on the reflector from the light emitting/receiving device.

摘要： The invention relates to a geared motor comprising a first brushless electric motor part having a stator, a rotor and a drive shaft, a second part having an output shaft and a reduction gear mechanism and an electronic part. The reduction gear mechanism comprises an output shaft, a worm and a toothed wheel designed to be engaged by the worm and to drive the output shaft in rotation. The geared motor comprises at least one rolling guide bearing disposed on the drive shaft and a multipolar magnet for measuring the position of the rotor. The rolling bearing is disposed between the measurement magnet and the worm such that the electric motor can be controlled depending on the measurement of the position of the rotor.

摘要： A droplet sensor includes an optical cover having an ellipsoid surface that is a portion of a spheroid, a light source disposed at or in proximity to a first focal point of the ellipsoid surface, and a light detector disposed at or in proximity to a second focal point of the ellipsoid surface. The ellipsoid surface includes an effective detection area configured to reflect light emitted by the light source toward the light detector, and an amount of light reflected by the effective detection area changes in accordance with adhesion of droplets on the ellipsoid surface. The optical cover includes a space having a hemispherical surface, the space being centered at the second focal point. The hemispherical surface includes a transmission scattering surface on a region that receives the light reflected by the effective detection area.

摘要： Provided is a compact and high-strength cab capable of securing an excellent field of view for work. The cab includes a guard protecting a cab body, and a wiper having a blade to wipe a front window member and a blade actuator for actuating the blade. The guard includes a pair of side pillars and an actuator housing beam interconnecting the side pillars and housing the blade actuator. The actuator housing beam includes a hollow beam body formed with a body opening and a front-rear partition plate partitioning the inside of the beam body into front and rear sections. The body opening allows the blade actuator to be assembled to the front-rear partition plate therethrough.

摘要： A wiper system for a vehicle is provided. The wiper system includes a driving assembly. The wiper system further includes a supplementary wiper having a first end that is coupled to a first pivot point of the driving assembly. When the wiper system is activated, the driving assembly is configured to swing the supplementary wiper about the first pivot point from a resting position to an extended position. The supplementary wiper is configured to be statically disposed at the extended position to prevent water from passing over one of two A-pillars of the vehicle to a side window of the vehicle. When the wiper system is deactivated, the driving assembly is configured to stow the supplementary wiper back from the extended position to the resting position.
