Abstract: An arrangement for actuating a shift element includes a shift pawl (3) pivotably mounted about a pivot axis (2) and a rotatable shift ring (4) with an outer toothing (5). A first end (6) of the shift pawl (3) is assigned to the outer toothing (5) of the shift ring (4), and a second end (7) of the shift pawl (3) is assigned to a shift gate (8) that actuates the shift pawl (3). A first contact line region (10) between a contact surface course (11) on the first end of the shift pawl (3) and a contact surface course (12) on the outer toothing (5) of the shift ring (4) is designed such that a contact engagement angle (?) of the shift pawl (3) of approximately 94° plus/minus 3° is produced between a first leg and a second leg.

Abstract: An arrangement for actuating a shift element of a gearbox includes a rotatably mounted and preloaded shift pawl (2) and a shift ring (3) with an outer toothing (4) and assigned to a gearbox element. A first end (8) of the shift pawl (2) is assigned to the outer toothing (4) of the shift ring (3) so as to lock or release the shift ring (3) in order to shift a gear stage, and a second end (9) of the shift pawl (2) is assigned to a shift gate (6) of a shift drum (5) that actuates the shift pawl (2). The shift pawl (2) is operatively connected to at least one double torsion spring (10) in order to apply a preload force.

Abstract: An arrangement for actuating a shift element for a bottom bracket gearbox (1) includes a shift ring (4) rotatably mounted in a housing (3) and assigned to a gearbox component. A shift pawl (5) for locking or releasing the shift ring (4) is assigned to the shift ring (4) for shifting a gear stage. A support region mechanically reinforces the housing (3) and is provided at least along a contact region (14) between an inner wall (8) of the housing (3) and an outer circumference of the shift ring (4). The contact region (14) is defined by reaction forces (16) acting when the shift ring (4) is locked.

Abstract: A bottom bracket gearbox for a micromobility vehicle (1) includes at least one shift element. Each shift element includes a shift ring (3) with an outer toothing (4). The shift ring assigned a shift pawl (5) for locking or releasing the shift ring (3) of the shift element. The shift ring being assigned to a gearbox component. At least one rotatably mounted shift drum (7) for actuating the assigned shift pawl (5) is axially parallel to a central axis of rotation of the gearbox (6). A shift actuator (8) is arranged in the interior of the shift drum (7), which is formed, at least partially or in sections, as a hollow shaft.

Abstract: A gear set arrangement (10) for a bicycle gearbox (400) includes a planetary assembly, a stationary component (24), a first and a second brake (B1, B2), and a first and a second freewheel clutch (F1, F2). One planetary gear set (12) of the planetary assembly includes a first rotary element, a second rotary element, and a third rotary element. The first rotary element is rotationally fixable on the stationary component (24) by the first brake (B1). The first rotary element is connectable to the output (36) by the first freewheel clutch (F1). The second rotary element is rotationally fixable on the stationary component (24) by the second brake (B2). The second rotary element is connectable to the output (36) by the second freewheel clutch (F2). The third rotary element is connected to the input (34) for conjoint rotation. The gear set arrangement (10) is configured to provide three ratios.

Abstract: In order to correct for fixed pattern noise in the signals of an image sensor, image signal values are read out from the pixels of the sensor. Individual correction values are added as analogue quantities to the image signal values via a signal path having a defined transfer function. Parameters which are characteristic of the defined transfer function are provided in a memory and the individual correction values are calculated in a correction value calculating unit using the parameters provided.

Abstract: A light reflector for photographing, filming or taping, especially for outdoor shooting, includes a plurality of panels of identical size and having at least one reflecting side, and connectors for butt-jointing the panels to one another. Abutting panels are joined together at their edges by connectors of U-shaped configuration, whereas the interconnection of four contiguous panels is realized in the center by connectors in the form of two metal plates which are secured to one another by a central screw bolt.
