  • Patent number: 5686897
    Abstract: A self-testing electronic personnel grounding device (wrist strap) for the purpose of dissipating static electricity from an individual. It uses a built-in electronic circuitry to detect a break in the electrical continuity in the wrist strap and alerts the wearer when there is a break in electrical continuity owing to broken connections along the dual wire coil cord or at the adjustable elastic wrist band, when it is improperly worn, or when the wearer's body resistance is too high. This device operates on a watch (Nickel-Cadmium, NiCd) type battery to provide the energy source to light an LED (Light emitting Diode) to indicate that there is a break in electrical continuity. The electronic circuitry is designed such that if the wrist band is improperly worn, causing ineffective contact between the human skin and the conductive side of the wrist band, the LED indicator will come on signaling a break in electrical continuity.
