Abstract

Abstract The certain quantity of light energy sufficient to effect lifelessness in each of a particular type of hairs is provided to the tip of a hand held probe (18) each time a switch (22) is closed, independent of the duration of the switch closure. A foot switch (22) is actuated to provide a series of timed and spaced pulses of light energy for a period 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. Alternatively, four foot switches can be provided, one of which can be depressed to provide one of four fixed periods of light pulses. Commonly, 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.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 102 words
A method of photoepilation of a plurality of hair bodies of at least one type wherein light energy is conducted from a source to the hair root or the vicinity thereof by way of the tip of a probe by actuating a switch coupled to the source for the duration required to provide light energy sufficient to effect lifelessness of the hair body and repeating such process for affecting each of the plurality of hair bodies, characterized by the steps of selecting a certain period and applying the light energy by actuating the switch for a duration independent of said period selected.
Claim 2
Independent Claim 102 words
A method of photoepilation of a plurality of hair bodies of at least one type wherein light energy is conducted from a source to the hair root or the vicinity thereof by way of the tip of a probe by actuating a switch coupled to the source for the duration required to provide light energy sufficient to effect lifelessness of the hair body and repeating such process for affecting each of the plurality of hair bodies, characterized by the steps of selecting a certain period and applying the light energy by actuating the switch for a duration independent of said period selected.
Claim 3
Dependent Claim 25 words
The photoepilation method according to claim 1 characterized in that the step of selecting a certain period includes varying the components of a timer circuit.
Claim 4
Dependent Claim 37 words
The photoepilation method according to claim 1 characterized in that the step of selecting a certain period includes selecting one of a plurality of switches, each switch being associated with one of a plurality of certain periods.
Claim 5
Independent Claim 96 words
An apparatus for performing photoepilation of a plurality of hair bodies of at least one type, including a source of light energy, a probe terminating at a tip and an optical cable coupled between the source and the tip for conducting light energy therebetween and a switch for energizing said source; characterized by a control circuit (41, 62) coupled between the source (38) and the switch (22, 74) and capable of being energized by actuation of the switch to produce light energy for a certain period independent of the length of time the switch is actuated.
Claim 6
Independent Claim 96 words
An apparatus for performing photoepilation of a plurality of hair bodies of at least one type, including a source of light energy, a probe terminating at a tip and an optical cable coupled between the source and the tip for conducting light energy therebetween and a switch for energizing said source; characterized by a control circuit (41, 62) coupled between the source (38) and the switch (22, 74) and capable of being energized by actuation of the switch to produce light energy for a certain period independent of the length of time the switch is actuated.
Claim 7
Dependent Claim 43 words
The photoepilation apparatus according to claim 4, characterized in that said control circuit includes at least one timer circuit (46, 64) operating for said certain period to produce said light energy independent of the length of time the switch (22, 74) is actuated.
Claim 8
Dependent Claim 23 words
The photoepilation apparatus according to claim 5, characterized in that said timer circuit (46) includes variable components (48) for setting said certain period.
Claim 9
Dependent Claim 61 words
The photoepilation apparatus according to claim 5, characterized in that said timer circuit (64) includes a plurality of fixed components (66, 68, 70, 72) arranged to provide a plurality of certain periods and there are a plurality of switches (78, 80, 82, 84) one for each certain period, actuation of one switch energizing the control circuit (62) for one certain period.
Claim 10
Dependent Claim 20 words
The photoepilation apparatus according to any one of claims 4 to 7, characterized in that all switches are foot-actuated switches.
Claim 11
Dependent Claim 29 words
The photoepilation apparatus according to any one of claims 4 to 8, characterized in that the probe is portable and capable of being hand-held during operation of said apparatus.
