Abstract: A coupling assembly includes a first shaft, a first housing configured to receive the first shaft, a second housing configured to attach to the first housing, a first gear positioned in the second housing and engaged with the first shaft, a first bearing positioned between the first gear and the second housing, a third housing, a second gear positioned in the third housing and engaged with the first gear, a second shaft that extends through the third body and engages the second gear, and a second bearing positioned between the second shaft and a wall of the third housing. The second shaft may rotate relative to the third housing and cause the first gear to drive the first shaft in an axial movement relative to the first housing and the second housing.

Abstract: A portable cleaning apparatus includes a handle and a wheel rotatably mounted to the handle having a plurality of scrubbing elements. A nozzle delivers fluid to the scrubbing elements to effect rotation of the wheel. The scrubbing elements can be secured to the wheel to limit pivoting movement of the scrubbing element in a direction of rotation of the wheel while permitting greater pivoting movement of the scrubbing elements in a direction opposite the direction of rotation of the wheel. A dispensing system mounted to the handle is remotely operable to position a dispenser of treatment material in the rotational path of the scrubbing elements to apply treatment material to the scrubbing elements.

Abstract: An exercise device including a support surface and at least two position sensors arranged along a sensing plane relative to the support surface, with the position sensors adapted to detect a presence of a user along the sensing plane. The exercise device further includes a controller in communication with the position sensors to determine a position of the user relative to the sensing plane. The controller has a closed loop feedback mode adapted to process at least one input parameter provided by the user, and to further measure a performance criteria of the user related to the input parameter and to provide feedback to the user indicative of a measurement of the performance criteria.

Abstract: An exercise device having position verification feedback capabilities. In one embodiment, the exercise device generally includes a base unit defining a support surface, at least two position sensors arranged along a sensing plane relative to the support surface for detecting the presence of the user along the sensing plane, and a controller in communication with the position sensors to determine the user's position relative to the sensing plane. In another embodiment, the exercise device is configured to simulate the activity of jumping rope. In a further embodiment, an exercise device is provided that is capable of measuring one or more parameters associated with a user's vertical jumping ability.

Abstract: A document shredder can be equipped with a shredding system for very high security. The shredding system can be made up of a first cutting stage with two corresponding cutting cylinders. After the first cutting stage a second cutting stage is provided for material cut in the first cutting stage. The second cutting stage can be made up of another pair of cutting cylinders. Alternatively, the second cutting stage can be made up of a third cutting cylinder reaching into one of the cutting cylinders of the first cutting stage, thereby establishing the second cutting stage.
