Abstract: A method for linking an exercise video to exercise equipment based on a machine readable code and an apparatus for processing exercise data. In one embodiment, a method is provided comprising posting an exercise video online wherein the video has a unique URL, creating a machine readable code for the unique URL, attaching the machine readable code to the exercise equipment, using a device having an application to decode the machine readable code, and displaying the exercise video on the device to a user. In one embodiment, an electronic device is provided comprising a display device, a memory storing a plurality of exercise data, an input element, and circuitry in communication with the display device, memory and input element.

Abstract: A fluid power cylinder having a cylinder with an elongated slot extending generally parallel to the longitudinal axis of the cylinder, a reciprocally movable piston and a strip sealing means for successively sealing the slot during movement of the piston. The sealing member is of a laminated construction and is constructed partially of a magnetized rubber-like material for magnetic attraction to the cylinder wall adjacent the slot. The sealing member also includes beveled edges for engagement with beveled edges adjacent the slot.

Abstract: A combination wheel brake assembly for connection with a wheel or other rotatable element comprising a rotatable axle, a spring applied, hydraulically released brake assembly, a wheel hub rotatably supported on the axle and adapted for connection with the wheel and free wheeling hub mechanism for selectively rendering the wheel hub free wheeling to permit the wheel to be freely rotated despite a loss or failure of hydraulic pressure and despite braking engagement of the braking elements.
