Patent Images
1. A fingerprint-operated padlock, comprising:
- a body;
a locking bar movably held in the body;
a fingerprint sensor held in the body;
a power source held in the body and connected to the fingerprint sensor;
means for activating the fingerprint sensor to read a fingerprint on a finger passed over the activated fingerprint sensor; and
means for comparing the fingerprint read by the sensor to at least one fingerprint stored in a memory to open the lock upon a valid comparison of the read fingerprint and the at least one stored fingerprint.

Abstract
A microprocessor-operated keyless entry padlock includes a fingerprint sensor for reading a fingerprint and comparing it to at least one fingerprint stored in memory in the padlock. If a match is found the padlock may be manually opened by a knob or automatically opened by actuating a drive gear to move a gear portion connected to a locking bar to open the locking bar.

16. A fingerprint-operated padlock, comprising:
-
a fingerprint sensor mounted on a padlock body having a locking bar;
a gear portion secured to the locking bar;
an actuating mechanism secured to a drive gear held in the body;
the drive gear cooperating with the gear portion;
a locking element secured to the drive gear;
a latch arm held in the padlock body and cooperating with the locking element;
a solenoid for releasing the latch arm;
a button held on the padlock body to activate the lock; and
a microprocessor and a power source held in the padlock body and operatively connected between the fingerprint sensor and the actuating mechanism to allow the locking bar to be opened if a fingerprint stored in a memory is matched to a fingerprint read by the fingerprint sensor.
