Abstract: A sensing apparatus for use in combination with a stationary bicycle comprises a housing that supports a source of emitted radiation and a detector of radiation of the same wavelength as that emitted by the source, fixing means for fixing the housing to an exercise device such that radiation is emitted towards a region of space that can be occupied by a part of a body of a user of the exercise device and selectively transmitted on to the detector depending on whether a part of a user's body is located within the space, a processor which measures at least one property of the radiation from the source that is passed to the detector and from the measured property produces an output signal indicative of the proximity of the user relative to the device within that space.

Abstract: A handlebar assembly (100) is disclosed comprising a lower base portion (101) which is adapted to support a handlebar (202) through a guide means which is so constructed and arranged to permit the handlebar (202) to move along a path relative to the base portion (101) whereby upon movement of the handlebar (202) along the path to the left or the right relative to a central position the handlebar (202) tilts and the center of the handlebar (202) moves downwards relative to the base portion (101) as well as horizontally from the central position. The assembly allows the handlebars to move in a way which mimics the movement of the handlebars of a bicycle. In a modification, the guide means may restrain the handlebar for movement up/down or forwards/backwards or side to side, again to provide a more realistic range of movement.

Abstract: A controller is disclosed, especially but not exclusively, for use in combination with an exercise apparatus. The controller comprises in one arrangement a handlebar assembly and one or more input devices, of at least one of the input device being responsive to movement of the handlebars. The controller may include a support such as a handlebar stem, and may provide output signals to a microprocessor in turn to control operation of a programme running on the microprocessor.
