ABSTRACT:
The certain quantity of light energy sufficient to effect lifelessness in each of a particular type of hairs, such as is found in a face, arm or back, is provided to the tip of a hand held probe each time a switch is closed, independent of the duration of the switch closure. This relieves the electrologist from having to manually count times, or the number of pulses of light energy applied to a hair body, to effect lifelessness therein. Such counting has been a major part of the photoepilation procedure, and a burden on the electrologist's faculties. In one embodiment, actuating a foot switch provides a series of timed and spaced pulses of light energy for a period, which is selectable by rotating a wiper of a variable resistor-capacitor circuit. The sum of the energies of the pulses over the selected period equals the certain quantity of light energy. In another embodiment, depressing one of four foot switches provides one of four fixed periods of light pulses. In both embodiments, the certain quantity of light energy is first determined for the hair type and then that certain quantity is used for all the hairs of that type to be removed.
