Abstract: A user of a self-powered electronic combination lock rotates an outer dial to cause generators to generate energy for storage in a capacitor bank. The user then rotates an inner dial to cause a microcontroller to sequentially display a combination of numbers, and presses the inner dial to select a displayed number. The microcontroller determines direction and extent of motion of the inner dial by receiving signals derived from Wiegand sensors placed in proximity to a magnetized disc which rotates integrally with the inner dial, and controls the display of numerals on an LCD display accordingly. When the microcontroller determines that a correct combination has been entered, it activates a motor to move a motor cam to act directly on a locking lever so that the locking lever can engage a drive cam integrally linked with the inner dial, to allow the inner dial to withdraw the lock's bolt.

Abstract: A vehicle detention device provides a pair of stopper blocks, where one of the stopper blocks moves on a guide shaft relative to the other stopper block secured to the guide shaft. A locking device is provided in order to prevent the movable stopper block from shifting away from a tire so that both the stationary and movable stopper blocks remain in contact with the tire at both sides of ground contact point to prevent rotation of the wheel with the tire mounted thereon. Using a pair of chains, the wheel is secured and placed under detention with the stopper blocks closely held in contact with the tire. Since the mechanical components necessary for releasing the tire and wheel are fully concealed by a key-actuated cover unit, no one can readily remove the vehicle detention device from the restrained vehicle without operating a proper key, thus securely detaining the vehicle.

Abstract: A security apparatus for attaching a portable unit to be protected to a supporting surface. The security apparatus includes a normally deactivated passive locking unit, which is activated by an electronic key unit, which is portable and moved adjacent to the passive locking unit to power it. The key unit includes a device for coupling electromagnetically the key and the locking units to transmit electrical power therebetween. A magnet is concealed within the security device to activate the electronic key, only when it is placed in the proper position relative thereto. Additionally, a mechanical arrangement for a locking pin is employed to further provide a level of sophistication before the actual unlocking of the device occurs.

Abstract: A cylinder assembly for a plate tumbler lock includes a plate tumbler which snap-fits into an assembled position by pushing the tumbler into its ward until a projecting detent flexes inwardly and passes by a retaining ledge in the side wall of the ward, and thereafter springs back outwardly so that the detent is retained by the ledge. A pair of notches, one located above and one below the tumbler detent, permit the tumbler to flex inwardly as the tumbler detent passes over the retaining ledge to eliminate any significant forces acting between the detent, the side wall of the tumbler ward and the retaining ledge, and thereby minimize the metal deformation of these components.

The cover includes a closed top end portion and a generally cylindrical sidewall extending from the closed top end portion so as to define a generally hollow cavity within the cover. Within the cavity of the cover is located an internally threaded portion, the threads of which are adapted to mate with the external threads on the bolt, so that the cover may be attached to the portion of the bolt that extends through its associated nut by threaded engagement therewith, when the cover is installed over the bolt and nut assembly.

Abstract: An envelope dispenser (50) for use in an automated teller machine includes a lockable access door (14). The door includes a slot (20), integral with its first face (16). The door is locked by the engagement of a first member (36) in a first notch portion (24) of the slot. The door is unlocked by an actuator (46) which upon the receipt of an electrical signal moves the first member into a central portion (28) of the slot. In this position the door may be manually moved to a fully open position by a user. In the open position the actuator urges the first member into a second notch portion (26), which releasably holds the door in the open position. In the open position envelopes stored in the machine may be accessed. From the open position the door can either be manually closed or automatically closed by the cessation of the electrical signal which enables a spring (44) to move the first member to the central portion of the slot.
