Abstract: Connection assemblies are disclosed herein for use with a computing device. In some examples, the connection assembly includes a collar that is rotatably disposed about a first connector and is transitionable between a first position and a second position. When the collar is in the first position, shoulders of a second connector coupled to the first connector interfere with corresponding shoulders within the collar to prevent withdrawal of the second connector from the first connector. When the collar is in the second position, the shoulders of the second connector are misaligned with the corresponding shoulders within the collar so that the second connector is freely removable from the first connector.

Abstract: In accordance with the invention, a key encasement is provided which enables an authorized user to obtain access to a key shrouded within the encasement by way of a combination lock. The key encasement generally includes a key, a thumb pin connected to the key, a lock assembly including a plurality of rotatable combination dials, and a housing assembly for concealing the key and lock assembly while in a shrouded, locked position.

Abstract: A lock is designed to prevent theft of a notebook computer and is formed of a housing, a metal fastening, a locking mechanism, and a retaining mechanism. The locking mechanism includes an arresting bolt with a conical tip and a dial block. The retaining mechanism includes a retaining bolt with an inclined surface, which is pushed by the conical tip of the arresting bolt such that a hooked end of the retaining bolt is engaged with a T-shaped slot of the notebook computer at such time when the wheels of the locking mechanism are turned randomly. When the wheels of the locking mechanism are turned to a set series of numbers, the conical tip of the arresting bolt moves away from the inclined surface of the retaining bolt, thereby resulting in disengagement of the hooked end of the retaining bolt with the T-shaped slot of the notebook computer.

Abstract: A lock for a computer has a housing, a core pivotally mounted to the housing, a latch formed on and extending out of the core, a rod coupled to the core. The rod has a flange end and a pair of pins extending from the flange end. A spring is disposed around the rod to provide a resilience to the pins, and a cable is pivotally connected to the housing. A case of the computer has a latch chamber and an entrance communicates with the latch chamber to allow the latch and the pin to enter the latch chamber through the entrance.

Abstract: A combination lock device includes a lock body, a lock snap structure locked in a lock hole of an article to be locked, and a drive structure for driving the lock snap structure. The lock snap structure includes a carrier, a first locking plate, and a second locking plate. The first locking plate is pivotally mounted in the carrier and may be vertically pivoted by the drive structure. The second locking plate may horizontally slide and displace relative to the first locking plate when the first locking plate is pivoted. The first locking plate has an end portion provided with a locking tongue portion. The second locking plate has an end portion provided with a resting snap portion. The locking tongue portion is vertical to the resting snap portion.

Abstract: A new keyless door knob security device with stabilizer arm for preventing access to a keyhole of a door knob to prevent unauthorized access. The inventive device includes a central shaft that has first and second ends and a longitudinal axis extending between the ends. A claw ring has a plurality of claws extending outwardly from it and an aperture through it. The central shaft extends through the aperture of the claw ring. The claws are adapted for grasping the door knob. A cover is slidably positionable along the central shaft such that sliding the cover in a first direction presses the claws towards each other such that the claws grasp the door knob. Sliding the cover in a second direction permits the claws to move apart from each other. A locking mechanism permits selective locking of the cover in a locked orientation and an unlocked orientation.

Abstract: A communications system is disclosed for switching connected communications terminal devices includes a central module including a processor-controlled base unit and a supplementary unit as well as at least one peripheral subscriber module and up to four subscriber transmission units. The peripheral subscriber modules and the subscriber transmission units allow the connection of communications terminal devices or, alternatively, the connection to public communications networks is possible. A switching element implemented in the base unit supports an ISDN-oriented interface to which up to four particularly low-cost subscriber transmission units may be connected. A small or mid-sized communications system having a modular construction can thereby be designed in such a fashion as to be expandable at the lowest expense while allowing flexibility of configuration.

Abstract: A steering column and steering wheel securing system comprising an upper component in a half box configuration having an upper face, parallel front and rear faces and side faces therebetween, the front and rear faces and side faces being formed with semi-circular recesses for receiving the upper half of a steering column, the upper component being formed with an exterior undulation adjacent projections on side thereof and with a wedge-shaped projection on the opposite side; a lower component in a half box configuration having a lower face, front and rear faces and parallel side faces therebetween, the front and rear faces being formed with semi-circular recesses for receiving the lower half of a steering column, one side edge being formed with holes for receiving the projections for pivotal coupling with respect to the adjacent side of edge of the upper component, a rectangular recess formed in the edge of the lower component between the projections for passage of a turn signal, the opposite side face of the

Abstract: The keyway of an automobile ignition lock can be protected by a key-shaped element which is secured by a combination lock to substantially preclude tampering with the automobile ignition lock. The guard device can be removed from the ignition lock keyway upon setting of the combination lock dials to the release position, and the regular ignition key can then be used with the ignition lock.

Abstract: A doorknob security apparatus (10) includes an upper housing (14) and a lower housing (16) which cooperate to form a cylindrical member. Hinge parts (24) and (26) are disposed on one edge of the halves and a locking member (20) is disposed on the other side to secure the two halves together. A cover (18) is mounted in annular grooves (28) and (30) on the periphery of the two halves (14) and (16). Semi-annular rings (32) and (38) are disposed on the interior of the housings (14) and (16) to form spaces (34) and (40) while receiving the gripping portion of the doorknob. An orifice is formed with the semi-annular rings to fit about the stem of the doorknob with a diameter less than gripping portion of the doorknob to prevent removal of the apparatus (10) from the doorknob. Reinforcing portions (44) and (46) increase the structural integrity of the semi-annular members (32) and (38).

Abstract: A bank lock for the ignition lock on the steering column of a motor vehicle includes a pair of arcuate arms which are hingedly connected at one end thereof and are of sufficient length to encircle a substantial segment of a steering column. A yoke element is carried by one of the arcuate arms and is adapted to be juxtaposed in close overlying relation to the housing of an ignition lock which protrudes from the steering column. One of the arcuate arms terminates in an end extension adapted to be positioned across the keyhole opening of the ignition lock and carries one of a pair of locking elements at its outer extremity. The second of the arcuate arms terminates in an end extension which is directed substantially perpendicularly to the end extension of the first arm and is adapted to be positioned in close relation to a diametrically opposed location of the ignition lock housing from the yoke.
