Abstract:
A retina scanning anti-theft device for motor vehicles includes a retinal scanner electrically connected to a vehicle&#39;s ignition system for preventing a starter from turning over an engine within the vehicle unless a proper retinal pattern is detected. The inventive device further has the capabilities of detecting when a driver is under the influence of drugs or alcohol by the dilation, constriction or expansion of the retinal blood vessels and thereby preventing the operation of the vehicle under such influence.

BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to Retina Scanning Devices and more particularly pertains to a new Retina Scanning Anti-Theft Device for Motor Vehicles for preventing the theft of an automobile. 
     2. Description of the Prior Art 
     The use of Retina Scanning Devices is known in the prior art. More specifically, Retina Scanning Devices heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new Retina Scanning Anti-Theft Device for Motor Vehicles embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the Retina Scanning Anti-Theft Device for Motor Vehicles 10 comprises a retinal scanner 20 capable of detecting and storing, a plurality of retinal patterns for a plurality of valid drivers for a vehicle. The retinal scanner 20 is electrically connected to a vehicle&#39;s ignition system for preventing starting of the vehicle unless the retinal scanner 20 detects a retinal pattern substantially similar to one of the valid drivers. The retinal scanner 20 preferably allows up to 30 seconds for an individual to start the vehicle upon detection of the retinal pattern substantially similar to one of the valid drivers. 
     As shown in FIG. 6 of the drawings, the retinal scanner 20 is electrically connected to a cut-off solenoid. The retinal scanner 20 is electrically connected to the cut-off solenoid by a coiled data cable 40 as shown in FIGS. 1 through 3 of the drawings. The cut-off solenoid is electrically connected mesially a starter motor&#39;s existing solenoid and the starter motor, whereby the circuit between the existing solenoid and the starter motor is closed only when the cut-off solenoid is closed. Thus, the cut-off solenoid disables the starter motor when the cut-off solenoid is open. 
     As shown in FIGS. 1 through 4 of the drawings, the retinal scanner 20 includes an encasement 22 substantially rectangular shaped with arcuate edges. A keypad 21 is secured within the encasement 22 for allowing manual control of the retinal scanner 20. A display 23 is secured within the encasement 22 for disclosing relevant information to a user. A scanning lens 28 is secured within the encasement 22 for reading the retinal pattern of the user. A central processing unit 50 is positioned within the encasement 22. The central processing unit 50 is electrically connected to the keypad 21, to the display 23 and to the scanning lens 28. An EEPROM chip is electrically connected to the central processing unit 50 for storing the retinal patterns of the valid drivers. A shading member 29 is secured around a peripheral edge of the encasement 22 surrounding the scanning lens 28 for preventing contamination during scanning of the user&#39;s retinal pattern. 
     As shown in FIGS. 2 through 5 of the drawings, the retinal scanner 20 includes a clip 24 secured to a rear surface of the encasement 22 for removably engaging a rectangular tube 26 secured within the vehicle. A length of adhesive tape 30 is secured to the rectangular tube 26 for mounting the rectangular tube 26 within an interior portion of the vehicle. 
     As shown in FIG. 6, the central processing unit 50 receives data from the retinal scanner, verifies the user&#39;s identification and triggers the timer unit to enable the starter motor. 
     In use, an individual who desires to operate the vehicle positions the scanning lens 28 near his or her eye. The scanning lens 28 reads the retinal pattern of the individual&#39;s eye upon the user pressing a read button of the keypad 21. The central processing unit 50 determines if the read retinal pattern substantially matches any of the retinal patterns of valid drivers stored within the EEPROM chip. If a match is successful, the retinal scanner 20 electrically closes the cut-off solenoid for 30 seconds allowing the individual to start the vehicle for 30 seconds following the successful retinal pattern match. However, if the central processing unit 50 is unable to determine a match, then the cut-off solenoid remains open thereby preventing the individual from closing the circuit between the starter motor and the existing solenoid within the starter motor. The present invention is also capable of measuring subtle differences within the retinal blood vessels caused by the individual being under the influence of alcohol or drugs, thereby preventing the driver from driving while under the influence of such drugs or alcohol. The present invention may be utilized for any commercial or noncommercial vehicle where an impaired driver could cause serious injury to another individual or steal the vehicle such as an airplane, a bus, a boat and various other vehicles. The present invention may be installed within an existing vehicle or it may be connected within a newly manufactured vehicle. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
