A wiper blade wipes a wiping surface. The wiper blade includes a blade rubber that is disposed in contact with the wiping surface, a wiper case that holds the blade rubber, and a state changing member that is accommodated in the wiper case and rotatable in the wiper case. The state changing member is rotatable in the wiper case or movable in a longitudinal direction. The state changing member is configured to change a curved form or rigidity in the longitudinal direction of the wiper blade in accordance with a curved form of the wiping surface when a rotational position or a longitudinal position of the state changing member is changed.

In order to reduce a driving frequency of a wiper configured to wipe a surface of an optical member on a front surface of a photographing lens, an imaging device includes:

a lens; an optical member provided on a front surface side of the lens; a wiper configured to wipe a surface of the optical member, and at least one processor or circuit which functions as a detection unit configured to detect at least one of a focal length of the lens, an aperture value, and a subject size; and a control unit configured to drive the wiper so that a driving frequency of the wiper is reduced as the focal length becomes longer, the aperture value becomes smaller, or the subject size becomes larger.

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.

A computer implemented method for controlling camera exposure to augment a wiper system of a sensor enclosure. The computer implemented method can detect a presence of a wiper in one or more images captured by one or more cameras. An exposure time of the one or more cameras can be adjusted. Wiper speed can be adjusted such that wipers move in and out of one or more field of views of the one or more cameras while the one or more cameras are capturing images.

This technology relates to system for clearing a sensor cover. The system may include a sprayer, a support, and a positioning device. The sprayer may be mounted to the support and direct a flow of fluid to the sensor cover. The positioning device may be configured to adjust the position of the sprayer on the support. The system may include a nozzle and the nozzle may be positioned to direct the flow of fluid to an area of the sensor cover. The system may include additional sprayers.

A system for audio control in a vehicle includes a speaker designed to output vehicle audio data in a cabin of the vehicle at a volume. The system further includes a microphone designed to detect microphone data in the cabin of the vehicle. The system further includes a memory designed to store an audio profile corresponding to desirable operation of the volume of the speaker. The system also includes an electronic control unit (ECU) coupled to the speaker, the microphone, and the memory and designed to control the volume of the speaker based on the detected microphone data and the audio profile.
