Patent ID: 7178929

Claim:
A system for producing a light and sound, comprising: a first wrist band having a first electrical circuit including a first switch operative in response to the presence of a magnetic field and a transmitter coupled to said first switch, said transmitter being effective to emit an RF signal in response to operation of said first switch; a second wrist band which mounts a permanent magnet, said second wrist band being movable into sufficient proximity to said first wrist band so that the magnetic field of said permanent magnet causes said first switch to move to a closed position; an article of footwear; a second electrical circuit mounted to said article of footwear, including: (i) at least one light source; (ii) a first integrated circuit coupled to said at least one light source; (iii) a second switch coupled to said first integrated circuit, said second switch being operative as a result of motion of said article of footwear, said first integrated circuit being effective to illuminate said at least one light source in response to operation of said second switch; (iv) a loudspeaker; (v) a second integrated circuit coupled to said loudspeaker; (vi) a receiver operative to receive said RF signal from said transmitter and then cause said second integrated circuit to sound said loudspeaker.
