ABSTRACT:
A pulse count scale includes a change of state detector circuit and an alert circuit which operate together with an electrical interrupter to detect when weight is applied on a scale platform and immediately connect power to a controller for a select interval. These circuits preserve battery power as well as providing simple operation, eliminating the requirement of actuating a separate switch prior to stepping onto the platform.
