Appl. No.:

09/832936

Inventors:

Gerald L. Dawson - New Port Richey FL
James P. Redden - Versailles KY

Assignee:

Kaba-Mas Corporation - Lexington KY

International Classification:

H02K 4100

US Classification:

310 12

Abstract:

A motor that is capable of both linear and rotational motion. One coil translates the motor along its axis for linear motion and a second coil causes the shaft to rotate. Coacting with the translate coil is a translate magnet where the north and south poles are oriented along the motor shaft. A segmented magnet where alternating north and south poles are located along the periphery of the magnet interacts with a rotation coil so that the interaction of the magnetic field of the segmented magnet and the magnetic field produced by the rotation coil cause the rotary magnet to rotate. Rotation of the rotary magnet, which cooperates with the shaft to which it is operably connected, causes rotation of the motor shaft.

International Classification:

H04Q 100

US Classification:

340 555, 340 522, 340 573, 340 52, 340542, 70332, 702784, 341 35

Abstract:

An electronic combination lock having a knob which has no divisions or markings relating to the numbers of the combination thereon. The rotation of the knob drives a generator, which produces electrical power. The power generated serves as a power source for the electronics of the lock. A knob position detector indicates to the microprocessor the speed and amount of rotation of the knob. The timing capabilities of the lock provides the opportunity to set the minimum time that can be used in the entering of the combination. The lock waits a period of time, typically, two seconds between the entry of one element of the combination and the lock permitting the entry at the next element of the combination. The microprocessor will also keep a count record of all the failed attempts to open the lock since the last successful operation. If the numbers of tries or attempts to unlock the lock equals or exceeds the number set in the microprocessor microcode, the lock will fail to open even if an authorized combination is subsequently entered.

Inventors:

John Doty - Lexington KY, US
Gerald Dawson - New Port Richey FL, US
Carl Cole - Lexington KY, US

International Classification:

E05B017/00

US Classification:

700275000, 070446000

Abstract:

The present invention is a mechanical lock manipulator and method of manipulating mechanical locks. There is a computer or microprocessor that controls a motor. The motor rotates the dial of a mechanical lock either clockwise or counterclockwise as directed by the computer. The computer receives an input from a transducer mounted to the lock or container. The transducer converts sounds and/or vibrations, into electrical signals. The computer collects data from the transducer and then evaluates this data and determines the opening combination for the lock.

Appl. No.:

8/268193

Inventors:

Gerald L. Dawson - Lexington KY
Daniel L. Thompson - Paris KY

Assignee:

Mas-Hamilton Group - Lexington KY

International Classification:

G06F 704
G06K 701

US Classification:

34082531

Abstract:

An electronic lock is provided with a timer capability to delay the operability of the lock for a preset period of time following the proper and correct entry of a combination into the lock. This delay prevents the lock from opening until both the time has expired and an access code entered following the time delay. If the access code entered after the time delay is incorrect, a further time delay or penalty delay will prevent the operator from an immediate attempt to enter a second access code. If a second access code is entered after the penalty delay and also is incorrect, the entire lock operation resets and the operation of the lock must begin with the re-entry of the correct combination. The entry of a combination to operate the lock which is offset by a predetermined value from the authorized combination will indicate by alarm at a remote monitoring center that the lock is being opened and may be opened under duress to the operator. The combination of the time delay as well as the entry of the alarm combination provide an opportunity for the monitoring center personnel either to react or to notify the appropriate security/law enforcement personnel to respond to a potential robbery.

Appl. No.:

7/763119

Inventors:

Gerald L. Dawson - Lexington KY
Daniel L. Thompson - Paris KY

Assignee:

Mas-Hamilton Group - Newtown Circle KY

International Classification:

H04K 100

US Classification:

380 23

Abstract:

A high security bolt lock is described having the ability to reencrypt the combination code for the lock each time a key is used and thus partially defeat the use of an unauthorized key. The lock may be operated by a temporary one time use key. The key for the lock carries a data storage means and battery to provide a date/time stamp and key identification for any key used. The key and lock may be coded to only allow access in a particular time block, or only in conjunction with an other key. The access to the lock may be controlled such that two keys must be used in a prescribed order to gain access through the lock.

Assignee:

C & M Technology, Inc. - Nicholasville KY

International Classification:

G06F 704

US Classification:

34082531

Abstract:

An electronic combination lock includes a combination lock having a dial with no markings thereon. Rotation of the dial drives a generator which produces electrical pulses. The voltage pulses serves as a power source for the electronics of the lock. The lock also includes a security feature to disable the lock if the combination dial is stopped between dial rotations for a period of time which indicates dialing by an automatic dialer.
