ABSTRACT:
A wrist-worn static charge warning device constructed and arranged to remain silent most of the time. The device emits an audible signal in the event that the charged individual wearing the device is approaching a grounded or poorly grounded electronic circuit, thereby warning against possible damage to the circuit before the occurrence of such damage. The device is based on the fundamental concept that movements of static charges can be detected by means of two RC circuits connected in a Master-Slave configuration.
