摘要： A wiping device for wiping an optical element clean of water or of particles includes a housing and a wiping element able to undergo a movement with respect to the housing, where the wiping device is configured to move in such a manner that such movement is caused by coupling a first unit in or on the wiping element with a second unit in the housing via a time-variable electromagnetic field. The wiping device may be used for wiping the surface of a lens or of a window, which lens or window is transmissive to visible light, ultraviolet radiation, and/or infrared radiation, and is preferably placed in front or as part of a camera. In addition, a rear view device or driver assistant device for use in or on a vehicle including such a wiping device, and a method for wiping an optical element are provided.

摘要： A wiper device for a small and curved surface such as a spherical surface of an optical element includes at least one elongate wiper element with two ends, two drive units to which the ends of the wiper element are attached so that the wiper element can be moved on the surface of the optical element using the two drive units, and at least one contacting means for bringing the wiper element into contact with a surface of the optical element, the contacting means shapes the wiper element around at least that part of the surface which is exposed to the environment due to an opening provided by the housing and is to be cleaned.

摘要： A method for identifying a signaling state of at least one signaling device including a traffic light includes obtaining at least one image which includes an image of the at least one signaling device, extracting a region of the at least one image which includes the image of the at least one signaling device, detecting the at least one signaling device within the extracted region of the at least one image, and detecting a signaling state of the signaling device after detecting the at least one signaling device within the extracted region.
