Patent ID: 7071828

Claim:
A flashing device wearable by a person to display a person's body motion, the flashing device comprising: a band configured to be detachably secured around a body part of the person, the band defining a cavity having a surface; a plurality of light emitting diodes disposed for visibility on the band; contained within the cavity, a flashing circuit comprising: a voltage source, a motion switch including a conducting element movable in a space defined by a plurality of conducting parts, the motion switch closing to produce a trigger signal when the movable element contacts two adjacent conducting parts in response to body motion of a person wearing the flashing device, a control circuit having an interface pin coupled to the voltage source, an input pin coupled to the motion switch and one or more output pins coupled to the plurality of light emitting diodes, the control circuit responsive to receipt of the trigger signal at the input pin to generate a pattern of electrical signals at the one or more output pins for selectively illuminating the plurality of light emitting diodes in a flashing pattern.
