Lock arrangement including a counterpart of the lock and a lock with a lock case. The lock case, which can be installed in a door, includes a locking latch and a latch mechanism, which includes an electrical device for opening and/or closing the locking latch. The counterpart of the lock can be installed in the frame of the door. A device for wirelessly sending electrical power to the lock case and/or into connection with the lock case is arranged in the counterpart of the lock; a mechanism is arranged in connection with the lock case for wirelessly receiving electrical power from the device for sending electrical power that is arranged in connection with the counterpart of the lock. Electrical power is arranged to be transmitted from the device for sending electrical power to the mechanism for receiving electrical power, when the lock case and the counterpart of the lock are at a certain distance from each other. The mechanism for receiving and device for sending electrical power are also arranged to transfer encrypted information relating to the operation of the lock.

A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock.

A wireless ultra-low power portable lock may be realized as a lock apparatus including: a locking mechanism having at least locked and unlocked states, the locking mechanism operable to provide physical resistance to being unlocked when in the locked state; an actuator operable to move the locking mechanism from the locked state to the unlocked state in response to a received signal; and a controlling unit configured to control the actuator and to receive one or more signals from one or more devices external to the lock apparatus.

An energizable electromagnet of a door locking system is affixed to the door or the door frame for electromagnetically attracting an armature affixed to the other. A power control circuit is configured to selectively energize the electromagnet using a pulse-width modulated current cycle wherein two levels of magnetic force may be selectively applied to the system. A door position sensor is configured to provide a first communication signal to the power control circuit when the door is in a closed position. A second communication signal is provided when the door is not in the closed position. The electromagnet is energized at the lower level of magnetic force when the power control circuit receives the first communication signal and at the higher level of magnetic force only when an unauthorized attempt to open the door is initiated.

The invention concerns a system (1) to provide access to premises (P1-P4) that comprise entrances (E1.1, E1.2, E2-E4) locked by means of electromechanical key locks (L1.1, L1.2, L2-L4), which for locking and unlocking are powered by insertion and actuation of at least one programmable key (24). In said system (1) an administrator (10) contacts a service unit (20) in possession of a programmable key (24) and provides it with synchronization data (13) for an electromechanical key lock (L1.2) of at least one entrance (E1.1) of at least one premise (P1) at an exact geographic position of a site (S).

For secure and safe access control, a method authenticates a user of an equipment unit with a user credential. The method determines an equipment status for the equipment unit. The equipment status includes one of energized and un-energized and one of locked and unlocked. The method determines whether the user is authorized to access the equipment unit with an equipment authorization. The determination that the user is authorized is based on the equipment status. In response to the user being authenticated and authorized to access the equipment unit energized or the user being authorized to access the equipment unit un-energized and the equipment unit being un-energized, the method releases a unit lock for the equipment unit with a unit lock credential and the user credential.

The embodiments presented within provide methods, devices, and systems that improve access control through the use of smart cylinder locks. In one embodiment, a smart cylinder may perform a process including receiving a key, emitting an energy source of electromagnetic radiation; detecting a change in the energy source due to a physical property of the key, determining the physical property of the key from the change in the energy source, comparing the physical property with a predetermined value, and engaging a mechanism operatively coupled to a locking device that allows the locking device to lock or unlock when the physical property matches the predetermined value.

An access control system includes an electrically powered access control device for locking and unlocking a barrier, and an access controller coupled to the access control device. A Power over Ethernet (PoE) circuit receives power over an Ethernet cable and powers the access control device and the access controller. An active power supply buffer connects the access control device and the access controller with the PoE circuit.

Systems, devices, and methods for controlling access to a secure space are disclosed. The system includes a locking device fastenable to an access point of the secure space, a server, and a network for communication between the locking device and server. The server includes a storage unit to store authorization data for the locking device and the user computing device, and a processing unit for receiving a request from the user computing device to access the locking device; authenticating the user computing device; generating authorization data; and providing at least part of the authorization data to each of the locking device and the user computing device. The locking device includes an actuator, a memory, and a processing unit for receiving a security command from the user computing device; determining whether the security command includes requesting data that corresponds to the authorization data; and generating a control signal for the actuator to move the locking device based on the security command.

A near-field communication (NFC) entry device provides remote keyless entry (RKE) into an enclosure having an RKE control unit, a door, and a door actuator. The NFC entry device includes a housing and a printed circuit board assembly (PCBA). The housing mounts to the enclosure. The PCBA is enclosed within a cavity of the housing, and includes first and second surfaces, an RF antenna and an inductor coil connected to the first surface, and an NFC communication chipset connected to the second surface. The NFC entry device passively harvests energy from a battery powered mobile device via the inductor coil and stores the energy in the capacitor. The passively harvested energy is used to communicate a control signal to the RKE control unit, via the RF antenna, which activates the door actuator. A standby battery may be used when the capacitor is insufficiency charged.
