An electronic lock cylinder contains: a receiving sleeve, a lock head, a fastener, a rotation element, a rotatable actuation element, a driven element, a drive motor, a resilient element, an operation element, a locking element, and a locating cap. Thereby, the drive motor moves clockwise or counterclockwise to drive the rotary column to rotate 90 degrees and to simultaneously actuate the driven element, the drive motor, the resilient element, and the engagement projection of the operation element to move forward or backward to rotate or rotate idly in the notch of the locking element, thus saving energy and obtaining environmental protection.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

An actuating device (12) comprising a stationary structure (20); an actuating element (22) rotatable relative to the stationary structure (20); an electric power source (24, 82); a spindle (26) arranged to be rotated by rotation of the actuating element (22); a locking member (28) movable between a locked position (66) and an unlocked position (86); an electromechanical transfer device (30, 84) arranged in the spindle (26), the transfer device (30, 84) being configured to adopt a locked state (68) and an unlocked state (78); a receiver device (34) fixed with respect to the spindle (26), the receiver device (34) being electrically connected 62 to the transfer device (30, 84); and a transmitter device (32) fixed with respect to the stationary structure (20) and arranged to be electrically powered by the power source (24, 82), the transmitter device (32) being configured to wirelessly transmit power to the receiver device (34).

A removable lock core for use with a lock device having a locked state and an unlocked state is disclosed. The removeable lock core may include a cam member tailpiece which is moveable between a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which permits removal of the removeable lock core from the lock device which corresponds to the lock device being in the unlocked state. The removeable lock core may include an electro-mechanical drive assembly which in a disengaged state is decoupled from the cam member tailpiece and in an engaged state is coupled to the cam member tailpiece. A cam lock having a locked state and an unlocked state for use with a catch is disclosed.

A dual-contact electro-permanent magnet (EPM) assembly of an information handling system may comprise a plurality of high-coercivity magnets situated on opposite ends of a low-coercivity magnet, a first EPM magnetic contact disposed between a first of the plurality of high-coercivity magnets and the low-coercivity magnet, and a second EPM magnetic contact disposed between a second of the plurality of high-coercivity magnets and the low-coercivity magnet. The low-coercivity magnet polarity may correlate to a direction of current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet, and dependent upon the low-coercivity magnet polarity, the first EPM magnetic contact is capable of operating in an attractive magnetic state to attract a ferromagnetic contact of a peripheral device while the second EPM magnetic contact is magnetically neutral with respect to the ferromagnetic contact.

An arrangement (10) for a lock device (88a, 88b), the arrangement (10) comprising an input member (12, 106); a coupling member (26) movable between an uncoupled position (34) and a coupled position (80); an electromechanical actuator (28) comprising an actuating member (42) linearly movable between an uncoupling actuating position (44) and a coupling actuating position (78); and a torsion spring (30) having a first leg (62) and a second leg (64) movable away from each other against a deformation of the torsion spring (30), wherein the actuating member (42) is arranged to engage the first leg (62) and the second leg (64) is arranged to engage the coupling member (26) when the coupling member (26) is in the uncoupled position (34) and the actuating member (42) moves from the uncoupling actuating position (44) to the coupling actuating position (78). A lock device (88a, 88b) comprising an arrangement (10) is also provided.

A smart lock for securing a door is provided comprising: an actuator configured to actuate a lock mechanism between a locked and an unlocked position; a housing attachable to a first side of the door, retaining the lock mechanism and the actuator; a receiver configured to wirelessly receive a signal to control operation of the actuator; a key mechanism engageable with the lock mechanism so as to actuate the lock mechanism, the key mechanism for receiving a tail piece of a key cylinder; a handle mechanism engageable with the lock mechanism so as to actuate the lock mechanism; and a handle arranged to control operation of the handle mechanism extending from the housing on the first side of the door. The key mechanism and the handle mechanism are disengageable from the lock mechanism.

A puller assembly for use with a lock device is disclosed. The lock device may have an interchangeable core. The puller assembly includes a puller core body having an opening sized to receive at least a portion of an operator actuation assembly of the lock device, a first engagement surface positioned to engage a portion of a rear end of the operator actuation assembly of the lock device, a second engagement surface positioned to engage a portion of a front end of a core assembly of the lock device, and an actuator which is moveable to alter a separation between the first engagement surface and the second engagement surface.
