Biometric safety and security system
First Claim
1. A biometric safety and security system comprising an enclosure containing a retracted key that can be extracted from said enclosure only after a person assigned to use said key has had their identity verified and the person'"'"'s blood alcohol content (BAC) has been verified to be below a preset legal limit.

Abstract
A biometric safety and security system (10) that is designed to prevent a person that is inebriated or that is not assigned the use of a particular vehicle ignition key (170) from starting the vehicle. The system (10) utilizes an enclosure (50) that houses an electronics circuit (12) that includes a microcontroller (14), a fingerprint scanner (26), a speech verifier (28), a breath analyzer (29) and the ignition key (170) which is normally retracted into the enclosure (50). To extract the key (170) a person must verify their identity by means of the fingerprint scanner (26) and/or the speech verifier (28), and also verify their sobriety by means of the breath analyzer (29). If the person'"'"'s identity and sobriety are verified a signal is sent to the microcontroller (14) where a signal is produced that activates a motor interface (32), that operates a d-c motor (34) that extracts the key from the enclosure (50).

28. A biometric safety and security system comprising an electronics circuit contained within an enclosure which also encloses a key that when not in use is in a retracted position, wherein said key can be extracted only after a person assigned to use said key has had their identity verified and the person'"'"'s blood alcohol content (BAC) has been verified to be below a preset legal limit, said electronics circuit comprising:
-
a) a microcontroller that fimctions in combination with a memory circuit to control the operation of said electronics circuit, b) a universal serial bus (USB) interface that is connected to said microcontroller, said USB interface having means for allowing data supplied to and from said microcontroller to be uploaded and downloaded and to allow external peripherals to be attached and powered, c) a microwire interface having an input and an output, wherein the output is connected to said microcontroller, d) a power distribution circuit that is connected to the input of said microwire interface and that includes a rechargeable battery and a battery charging circuit, wherein said power distribution circuit produces a plurality of power outputs that are distributed to the elements comprising said electronics circuit, wherein the outputs from said power distribution circuit are processed by said microwire interface prior to applying the outputs to said microcontroller, wherein said power distribution circuit further comprises a +5 volt d-c adapter port and a USB port that can be attached to an external power source to charge said rechargeable battery, e) a programmable keypad that is connected to said microcontroller, and that is designed to enter at least the following data;
(1) a person'"'"'s PIN, (2) BAC legal limit, (3) date and time, (4) emergency medical data, and (5) valet parking delay. f) a first means for verifying the identity of a person that is assigned to use said key comprises a fingerprint scanner that is connected to said microcontroller and is accessible from said enclosure, wherein when a person places a finger on said fingerprint scanner, said scanner produces a fingerprint verification signal that is applied to said microcontroller for verification against fingerprint data that is pre-stored in said microcontroller, wherein if the person'"'"'s fingerprint is verified as belonging to the person assigned to use said key, said microcontroller produces a fingerprint verified signal that is passed to said electronics circuit for further processing, g) a second means for verifying the identity of a person that is assigned to use the key is further comprised of a speech pattern verifier that is accessed via a microphone aperture located on said enclosure, wherein when a person speaks a speech verification password into said microphone, said speech pattern verifier produces a speech verification signal that is applied to said microcontroller, wherein if the person'"'"'s speech pattern is verified as belonging to the person assigned to use said key, said microcontroller produces a fingerprint verified signal that is passed to said motor interface for further processing, h) a breath analyzer having means for accepting a breath sample from a 15 person and providing a breath verification signal that is applied to said microcontroller for verification that the person'"'"'s blood alcohol content (BAC) has not exceeded a preset legal limit that is pre-stored in said microcontroller, wherein if both the identity and breath protocols pass, the ignition key is extracted conversely, if either the identity or the breath protocol is not passed, the key remains in the retracted position, i) an LCD display that is connected to said microcontroller and allows a person to view at least;
(a) battery status, (b) programming status, (c) verification of person'"'"'s identity and sobriety, (d) date and time, (e) emergency medical data, and (f) 30-day breath analyzer history. j) a d-c motor that is connected to said key via a worm gear assembly that positions said key in either the extracted or the retracted position as controlled by said microcontroller, k) a motor interface that is connected to said microcontroller and having means for producing a polarized power signal that is applied to and powers said d-c motor that extracts and detracts said key in accordance with the polarity of the applied power signal, l) a microphone, m) a loudspeaker, n) an audio codec having an input connected to said microcontroller and outputs consisting of a digital signal that is connected to and operates said microphone and an analog signal that is connected to and operates said loudspeaker, and o) a set of three LEDS that are located on said enclosure and that indicate the status of said battery in terms of “
battery low”
