The present invention provides a vehicle-mounted imaging device that can notify a user of contamination, at a facility, a home or the vicinity thereof in which the user tends to easily eliminate the contamination on a lens or a protective glass of the lens of a camera. The vehicle-mounted imaging device includes: an accretion diagnosis unit 22 that diagnoses a state of the contamination that has been accreted on a lens of camera sections 11A, 11B, 11C, and 11D or on a protective glass of the lens; and a contamination notification determination unit 23 that determines the presence or absence of a notification of the contamination, on the basis of positional information on a predetermined type of facility that is obtained from a navigation device 31 having a database 31b containing a GPS 31a, a map and peripheral facility information, and of a vehicle, wherein when it has been determined by the accretion diagnosis unit 22 that a contamination level is a threshold value or higher, a route to a destination has been set by the navigation device 31, and it has been determined by the contamination notification determination unit 23 that the facility exists in a predetermined distance range from the route, the vehicle-mounted imaging device notifies the user that there is the contamination, by the display device 32 and/or a speaker device 33 provided in the vehicle.

A wiper system 1 has wiper blades 4a and 4b driven by a wiper motor 7 and washer nozzles 16 for ejecting washer liquid in association with operation of a washer motor 18. The wiper motor 7 and the washer motor 18 are drive-controlled by a controller 9 housed in a motor unit 6. The controller 9 uses a FET module 10 for a three-phase motor provided with seven FETs. In the FET module 10, a battery reverse connection protection part 31 is provided with one FET (34a), a wiper motor drive part 32 is provided with four FETs (34b to 34e), and a washer motor drive part 33 is provided with two FETs (34f and 34g).

This disclosure relates to techniques for implementing a windshield wiper system with an actively movable platform. The windshield wiper system can include a windshield wiper arm mechanically coupled to a platform and an actuator mechanically coupled to the platform. The windshield wiper arm can be configured to move through a planar range of motion that is substantially parallel to a surface of a vehicle when the platform is positioned at a first spatial location and the movable windshield wiper arm can be configured constrained from moving through the planar range when the platform is positioned at a second spatial location.

In accordance with at least one aspect of this disclosure, a system includes a wiper arm configured to sweep along a sweep zone defined between a start position and an end sweep position, a wiper drive shaft operatively connected at a proximal end to the wiper arm to drive the wiper arm between the start position and the end sweep position, a tracer operatively connected to a distal end of the wiper drive shaft configured to mimic movement of the wiper arm, and one or more position indicators disposed proximate a distal end of the tracer corresponding to at least the start position and the end sweep position, where the distal end of the tracer configured interact with the one or more limiters during operation of the wiper arm.

An emergency windshield wiper system that attaches to the windshield of a vehicle. The system comprises of a platform that is used to secure a battery, a motor, a control, a pair of suction cups, an oscillating gear and an arm that holds a windshield wiper. The suction cups are positioned at opposite ends of the platform so that a center of gravity is created at a midpoint of the platform. The oscillating gear is positioned at the midpoint of the platform and it connects via a connector gear rod to a motor gear that is attached to the motor. The battery, motor and the control are operatively connected. The oscillating gear attaches to the arm. The windshield wiper inserts within the arm of the windshield wiper system.
