  • Patent number: 6421222
    Abstract: The present invention involves an apparatus for dissipating electrostatic charges while providing protection against undesirable high amperage current, and takes the form of ESD (Electrostatic Dissipating) footwear, which protects against the accumulation of electrostatic charges by dissipating the charges through controlled ohmic path leakage between the user and a ground. The apparatus is primarily constructed of several conductive layers and a set of parallel resistors, whereby the conductive layers are adapted to integrate with existing construction techniques of a multitude of footwear styles, in addition to a wide variety of electrical devices. The parallel resistors provide fail-safe operation and accurate, repeatable resistance for the apparatus. The apparatus can be attached to or embedded within a multitude of footwear styles or other devices to provide electrostatic dissipation between the user or electrical device and a ground.
