Claim 1
Independent Claim
199 words
The static dissipator for protecting computer systems and other digitized electronic equipment of the type designed to operate at voltages that are changing at rates less than approximately 100 million volts per second which comprises: a conductive element defining a touchpoint locatable in close proximity to the equipment to be protected and accessible to a person constituting a potential charge-carrying entity, said conductive element having a charge-carrying capacity which is smaller than the charge-carrying capacity of the charge-carrying entity; and, grounded resistance means electrically connected to said conductive element sized and adapted so that an arc discharge time constant has a value of no less than about one half millisecond to effectively surpress the rates of change of the currents and voltages accompanying the discharge of any electrostatic energy carried by said charge-carrying entity to be slow enough to be no greater than that rate of change of currents and voltages at which the equipment to be protected is designed to operate yet will occur fast enough so that within a time interval of no greater than approximately 100 milliseconds the charge on the charge-carrying entity is reduced to a level that is safe for the equipment being protected.
