Abstract

A fingerprint biometric lock is provided which includes a locking mechanism that restricts the movement of an object that is to be unlocked, a movement restriction electronic circuit that restricts the unlocking of the object by the locking mechanism, a fingerprint sensor that detects a fingerprint pattern, a memory device that stores an enrolled fingerprint code data, a verifying unit that determines whether an offered fingerprint code, created from the fingerprint pattern sensed by the sensor, matches with any of the enrolled fingerprint codes stored in the memory device, a motor control unit that unlocks the locking mechanism through the movement restricting electronic circuit, when the offered and enrolled fingerprint codes match, and, a finger presence detector for powering a direct current to the sensor and the motor control unit.

Claims

1. A fingerprint biometric lock, comprising:

(a) a locking mechanism means that restricts the movement of an object that is to be unlocked;

(b) a movement restriction electronic circuit that restricts the unlocking of the object by the locking mechanism;

(c) a fingerprint sensor that detects a fingerprint pattern;

(e) a memory device that stores an enrolled fingerprint code data;

(f) a verifying unit that determines whether an offered fingerprint code, created from the fingerprint pattern sensed by the sensor, matches with any of the enrolled fingerprint codes stored in the memory device;

(g) a motor control means that unlocks the locking mechanism through the movement restricting electronic circuit, when the offered and enrolled fingerprint codes match; and

(h) a finger presence detector for powering a direct current to the sensor and the motor control unit.

2. The fingerprint biometric lock according to claim 1, wherein proximity detector transmits or receives a beam of light.

3. The fingerprint biometric lock according to claim 1 wherein the proximity detector is a micro-switch.

4. The fingerprint biometric lock according to claim 1 wherein the fingerprint sensor is capacitative-based.

5. The fingerprint biometric lock according to claim 1, further comprising a high security portable storage unit having two sides, a front, a back, a top and a bottom walls, at least one of the walls having a hinged panel for access to an interior of the unit when the locking mechanism unlocks the hinged panel.

6. The fingerprint biometric lock according to claim 5 wherein the high security portable storage unit is a gun safe.

7. The fingerprint biometric lock according to claim 6 wherein the control unit further comprises a servo motor having a shaft for driving a cam and a controller board, the cam including a magnet in substantial alignment with a magnetic sensor on the controller board for outputting a signal indicating a rotation of the shaft.

8. A method for unlocking an object in a secured storage, comprising the steps of:

(a) storing in a first memory means a power management sequence data;

(b) inputting in a second memory means finger detection data;

(c) using the first and second memory means to enroll an enabled finger print code;

(d) using the first and second memory means to sense an offered finger print code;

(e) determining whether the offered fingerprint code data verifies with the enabled fingerprint code; and

(f) outputting to a motor control unit a signal for unlocking a locking mechanism when the offered and a registered fingerprint codes match.
