Abstract

Abstract Apparatus is herein described for controlling an electrical power circuit in response to the electronic detection of a photo reflective substance on a predetermined portion of the human body. More specifically, a guide device is provided for positioning a portion of the human body in a predetermined location for the application of a photo reflective substance to a predetermined portion thereof. A source of radiation is provided and photo sensitive, electrical circuitry is positioned with respect to the last mentioned portion of the human body so that the photo sensitive circuitry becomes conductive upon sensing the reflection of radiation from the photo reflective substance. The dispensing apparatus for applying the photo reflective substance and the mechanical guiding means for positioning the portion of the human body with respect to the photo sensitive circuitry are arranged so that the portion of the human body concerned is relatively positioned in the same location, with respect to the dispensing apparatus, as it is with respect to the photo reflective sensing apparatus. In this manner, the photo sensitive circuitry is actuated only when radiation is reflected from the predetermined portion of the human body. In one feature of the invention, the source of radiation includes ultraviolet rays having a wave length in the range of 3,000 to 4,000 angstroms. In another feature of the invention, monochromatic filtering is provided whereby the photo sensitive circuitry is only actuated in response to the sensing of a particular color of photo reflective substance.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 146 words
Apparatus for controlling an electrical power circuit in response to the electronic sensing of a photo-reflective substance presented on a predetermined portion of the human body, comprising: guide means for positioning a portion of the human body in a predetermined location; dispensing means associated with said guide means for applying a photo-reflective substance to a predetermined portion of the human body in response to the positioning thereof by said guide means; a source of radiant energy; electronic means operable to actuate a power circuit in response to the sensing of a photo-reflective substance on the predetermined portion of the human body; and second guide means associated with said electRonic means for positioning the portion of the human body in the same identical predetermined position relative to said electronic means as presented by the relative position thereof with respect to said dispensing portion of said dispensing means.
Claim 2
Dependent Claim 146 words
Apparatus for controlling an electrical power circuit in response to the electronic sensing of a photo-reflective substance presented on a predetermined portion of the human body, comprising: guide means for positioning a portion of the human body in a predetermined location; dispensing means associated with said guide means for applying a photo-reflective substance to a predetermined portion of the human body in response to the positioning thereof by said guide means; a source of radiant energy; electronic means operable to actuate a power circuit in response to the sensing of a photo-reflective substance on the predetermined portion of the human body; and second guide means associated with said electRonic means for positioning the portion of the human body in the same identical predetermined position relative to said electronic means as presented by the relative position thereof with respect to said dispensing portion of said dispensing means.
Claim 3
Dependent Claim 111 words
Apparatus according to claim 1 wherein said guide means and said dispensing means include electrical circuitry adaptable for connection with a source of electrical power and operable to actuate solenoid means in response to the closing of said circuit by a switching means; said switching means being closed in response to the proper positioning of a portion of the human body by said guide means; and said solenoid means operable to position a dispensing portion of said dispensing means in engagement with the predetermined portion of said human body in response to the closing of said switching means when said electrical circuit is properly connected with a source of electrical power.
Claim 4
Dependent Claim 46 words
Apparatus according to claim 2 wherein said guide means includes a holder means for receiving a portion of the human body and operable to slidably guide said portion along a predetermined track as said holder means in moved there - along to a predetermined final position.
Claim 5
Dependent Claim 106 words
Apparatus according to claim 2 wherein said solenoid means and said dispensing portion of said dispensing means including first mounting means universally adjustable for movement in a single plane; said electronic means including photo-sensitive cell means and a second mounting means for adjustably moving said photo-sensitive cell means in a single plane; whereby radiant energy reflecting from said photo-reflective substance is operable to actuate the electrical power circuit in response to the actuation of said photo-sensitive cell means; and whereby said cell means is only actuated when said cell means receives radiant energy from photo-reflective substance precisely positioned in the predetermined portion of the human body.
Claim 6
Dependent Claim 42 words
Apparatus according to claim 4 wherein said photo sensitive cell means includes two photo sensitive cells associated with comparator circuitry; whereby said electronic means is actuated only when a predetermined difference in quantum of radiant energy is sensed between said two cells.
Claim 7
Dependent Claim 46 words
Apparatus according to claim 4 wherein said photo-sensitive cell means is provided with monochromatic filter means so that only a predetermined color of photo reflective substance will actuate said electronic means in response to the reflection of radiant energy therefrom through the said photo cell means.
Claim 8
Dependent Claim 31 words
Apparatus according to claim 5 wherein said source of radiant energy includes a source of ultra violet energy having a wave length in the range of from 3,000 to 4,000 angstroms.
