Abstract: Implementations of a back scrubber are provided. The back scrubber may be used to scratch, scrub, wash, apply moisturizer, and/or massage a user's back or a portion thereof. In some implementations, the back scrubber comprises a top surface, a bottom surface, a front surface, side surfaces, and a back surface. In some implementations, a cover may be used in conjunction with the back scrubber to provide a washing and/or scrubbing surface. In some implementations, the front surface may be contoured based on the anatomy of a human back. In some implementations, a rib may be located on the front surface of the back scrubber. In this way, a user may be able to better scrub the small of the back and/or other adjacent surfaces. In some implementations, the back scrubber may be used with a mount. The mount may be used to secure the back scrubber to a suitable surface.

Abstract: A burn-in control method and video processor for executing the same. The video processor intelligently recognizes aspects of a video image that are likely to cause burn-in, and responsive to such recognition, modifies the video image to prevent uneven aging of the pixels. According to one aspect of the disclosure, modifications are spatially made to an entire video frame, one or more selected regions of a video frame, or one or more individual pixels of a video frame. According to another aspect of the disclosure, modifications are temporally made to all frames in a video stream, selected frames in a video stream, or a single frame in a video stream.

Abstract: The invention relates to a ball draw-off apparatus for shaft prostheses with balls (3) which can be placed onto the prosthesis neck (2). The apparatus has two rotary bodies (5a, 5b) which are rotatably supported in a housing (4), which can in each case be rotated with a lever arm (6a, 6b) and which with their axes of rotation (7a, 7b) lie in a common plane and form an open gap S in the projection onto the plane F for the introduction of the prosthesis neck (2). The rotary bodies have a profile which with increasing rotation decreases the gap S for clamping the prosthesis neck (2) and causes an increase of the distance of its upper edge (9a, 9b) from the plane F in order to produce a draw-off force P at the placed on ball directly or indirectly via an intermediate body.
