Abstract: An apparatus for synchronizing an audio stream beat with a movement tempo enclosed audio device generating an audio stream. The detectors determine the beat per unit time of the audio stream and the tempo of movement of a user. Control input carried on a user's finger control the play of the audio device and the synchronization operation. In one aspect, the audio device and the control input are carried in a sleeve worn on a user's finger and wirelessly transmit the synchronized audio stream to headphones worn by a user. In another aspect, the audio device and an accelerometer for detecting user tempo are mounted in the headphone and wirelessly receive control input from the finger mounted control input.

Abstract: A membrane panel including at least one electrical component. The panel includes a rigid support member having substantially planar top and bottom surfaces. At least one void region, or hole, extends from the bottom surface of that support member. A flexible top member including at least one flexible layer, overlies the support member. A flexible bottom member including at least one flexible layer underlies the support member. The bottom member has its upper surface affixed to the bottom surface of the support member. Further, the bottom member includes an integral flexible tail. The bottom member includes at least one electrical component affixed to its upper surface with that component underlying and extending into an associated one of the void regions of the support member. An electrically conductive pattern is affixed to the upper surface of the bottom member and that pattern is electrically coupled to the component to permit its operation in an electrical network.
