In an aspect, the present disclosure includes a method, apparatus, and system for operating a security tag, comprising activating a piezo-electric component of the security tag to generate an electrical charge in response to an applied mechanical force on the security tag; determining whether a verification signal has been received by the security tag upon activating the piezo-electric component; and disengaging a mechanical component of the security tag based on a determination that the verification signal has been received.

A central access control system (10) includes a plurality of doors (44), a plurality of door locks (20) respectively mounted to the doors (44), a control device (33) connected to the door locks (20), and an unlocking device (40) for setting the control device (33) to be in an enabling state or a forbidding state. When the control device (33) is set to be in the forbidding state, the control device (33) outputs a forbidding signal to all of the door locks (20) to set the door locks (20) in a locking state. When the control device (33) is set to be in the enabling mode, the control module (33) outputs an enabling signal to all of the door locks (20), and a locking state or an unlocked state of a locking mechanism (24) of each door lock (20) remains unchanged.

The locking system can have an outer housing mounted to an outside face of the door, and an inner housing mounted to an inside face of the door, a wire conduit mounted to one of the inner housing and the outer housing and extending across the door to the other one of the inner housing and the outer housing, the wire conduit having two telescoping members, and at least one wire extending inside the wire conduit and connected between a first locking system component housed in the outer housing and a second locking system component housed in the inner housing.

Anti-vandalism padlocks are used to secure chains, latches or similar elements, consisting of two coupling armours, with a particular geometry according to their application, with a tumbler cam lock. This padlock does not have an exposed shackle nor any other similar element which may be subject to violation either by cutting, lever movements or the like.

A door lock uses a mobile device as an input interface. The door lock includes a latch device mounted to a door, an outer operating device mounted to an outer face of the door, and an inner operating device mounted to an inner face of the door. The outer operating device includes a contact-type connection interface for contact-type connection with the mobile device. After the mobile device is in electrical connection with the outer operating device, an input device of the mobile device is used to input a to-be-identified identification information to the door lock, and the door lock identifies whether the to-be-identified identification information matches authenticated identification information for subsequent unlocking operation or remaining in a locked state.

Lock system, mobile device and method for indicating the location of a lock with a mobile device, which mobile device sends and receives a radio signal and communicates with the lock via radio-frequency communication, wherein the lock is a lock that is openable electrically and by radio-frequency communication. In the solution of the invention the direction and/or strength of a radio transmission sent by a lock is measured with a mobile device, the location and/or direction of the lock in relation to the mobile device is determined on the basis of the measurement, and the location of the lock and/or the direction towards the lock is indicated with the mobile device to the user of the mobile device.

The present invention discloses a lock system, comprising a lock assembly that includes a hasp and an interlock mechanism detachably engaging with the hasp. Further included is a latch system that latches the interlock mechanism in a lock position.

An electronic locking device can be configured to become active from a low power state, receive physical input to unlock, and provide access to a replaceable power supply. An electronic locking device can use a combination of physical input and discovery of an authorized mobile device to enable transition from a locked state to an unlocked state. Authorization can be internally stored or externally obtained through a service. An electronic locking device can match a series of physical interactions to a series of stored interactions to enable transition from a locked state to an unlocked state, when an authorized device is unavailable. An electronic locking device can provide access to a replaceable power supply when a latch is released.

Systems and methods for providing secure locks having redundant access channels are disclosed. In some embodiments of the invention, the smart lock has a hardware processor, a power source, a cylinder, a button that forms a rose knob, and a rose protector. The rose knob and rose protector protect and conceal the hardware processor, the power source, and the cylinder. The rose protector forms an annular groove that slidably interlocks with the rose knob. The rose knob has a plurality of redundant access channels for receiving authentication information. The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel.

An locker for storing equipment is disclosed. The locker includes at least one first member defining a storage space with an opening for a user to access the storage space, a second member adjacent to said at least one first member, and defining a first side of an open locker slot, and a door having a first portion and a second portion. The first portion of the door being shaped to enclose the opening of the storage space. The second portion of the door extending from the first portion of the door and being shaped to form a second side of the open locker slot. The door having an unlocked state and a locked state. The unlocked state provides access to the storage space and the open locker slot. In the locked state, secondary equipment is maintained in the storage space and equipment is maintained in the open locker slot.
