Abstract
A radiant energy system includes an energy receiving member for receiving energy and for converting received energy into electrical signals. Current amplifying means are coupled to the radiant energy receiving member. Voltage comparator means are coupled to the current amplifying means to compare the voltage developed by the current amplifying means to a reference voltage. The comparator provides an output signal indicative of whether the voltage applied to the comparator input is sufficient to actuate the circuit. The output characteristics of the comparator can be selected to be consistent with TTL and data processing circuit drive requirements. The system is suitable for use wherein the radiant energy devices are employed as position indicators for moveable parts and or electrical isolation of postage meters.
