Abstract
A shoe, soap or other article incorporates an integrated circuit having a first and a second input gate, and one or more outputs that can serve to supply power to a like number of light sources, like LEDs. The first input gate is responsive to a motion signal and acts to cause the integrated circuit to deliver a pattern of power signals to the one or more outputs. The second input gate is responsive to a second motion signal, the second motion signal actually being two or more motion signals occurring at a pre-determined frequency that the integrated circuit detects. The second input gate logically acts to cause the integrated circuit to alternate between a sleep mode and an active mode. The first input gate is disabled by the integrated circuit when the integrated circuit is in sleep mode.
