An exemplary method includes transmitting a wireless power signal from an electrical device connected to line power, receiving the wireless power signal at an electronic access control device, and operating the electronic access control device using electrical power harvested from the wireless power signal. In certain forms, the method further includes adjusting an orientation of the antenna by which the wireless power signal is transmitted.

A keyless puck lock apparatus with wireless communications and power interfaces. Embodiments of the present disclosure provide a keyless puck lock system enabling a low cost and high security solution that is difficult to tamper with and defeat. In the preferred embodiment of the present invention, the system uses a keyless puck lock assembly that includes a hasp assembly and a keyless lock mechanism that does not require any physical mechanical keys so that it does not have a mechanical cylinder inserted therein to lock or unlock the puck lock. Accordingly, the keyless puck lock system in accordance with one or more embodiments of the present invention does not have a physical keyway which is a security attack point that is included in conventional hockey puck-type locks.

A safety handle for the control of access to machines or industrial plants comprises a main body (3, 4) adapted to be gripped by a user for moving the movable part (M) of the access (A), fixing means for fixing the main body (3, 4) to the movable part (M), an actuator (2) suitable to be associated with the main body (3, 4) to interact with control means associated with the access (A) upon closure thereof for enabling the machine or industrial plant to be controlled. The main body (3, 4) houses thereinside one or more signalling and/or control devices (25, 26) provided with electrical connection means for connection to one or more power and/or service circuits of the machine or industrial plant, at least one of the signalling and/or control devices comprising one or more light sources (25) adapted to emit a light beam.

A door-lock system for a household appliance, such as a washing machine and the like, of the type provided with a door, to which a hook is associated, and a member to be moved (C) of said household appliance, such as a washing drum (C) or the like, said door-lock system comprising motor means for operating said member to be moved (C) and a door-lock device, capable of interacting with said hook, to lock said door, characterized in that said door-lock system comprises a control unit, capable of controlling the power supply of said motor means and connected to said door-lock device, so as to control the power supply to hold said hook and to close said door.

An illustrative access control system includes a locking assembly operable in locked and unlocked states, and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, and energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between the locked state and the unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device.

Embodiments of the present disclosure provide a keyless puck lock system enabling a low cost and high security solution that is difficult to tamper with and defeat. In the preferred embodiment of the present invention, the system uses a keyless puck lock assembly that includes a hasp assembly and a keyless lock mechanism that does not require any physical mechanical keys so that it does not have a mechanical cylinder inserted therein to lock or unlock the puck lock. Accordingly, the keyless puck lock system in accordance with one or more embodiments of the present invention does not have a physical keyway which is a security attack point that is included in conventional hockey puck-type locks.

The invention provides a digital lock (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the digital lock (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100, 1001, 1002).

The invention provides a digital lock including at least two magnets. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to move to close the digital lock in the event of malicious attack, blocking the intruder thereby the magnets acting as a blocking pin, and the mechanical and/or electromagnetic energy of the attack is configured to move the hard magnet to seal the digital lock from the intruder.

An exemplary method generally relates to operating an access control device including a motor, a locking member, and a target component operably connected with the locking member. The motor may be operated to drive the locking member in a first direction from an initial position toward a desired position. When the locking member is blocked from moving beyond a blockage position, a target location of the target component is detected. The motor may then be operated to drive the locking member in a second direction opposite the first direction. The motor may then be operated to drive the locking member in the first direction toward the blockage position while monitoring the location of the target component. As the target component reaches the target location, the motor is supplied with a boost current to drive the locking member beyond the blockage position and toward the desired position.

A lock (1) with an exterior activation sensor (2) includes an interior electromechanical mechanism (3) with a corresponding power supply unit (4) and an exterior activation sensor (2) situated on the external part of the locker, and which is used in community lockers or similar, wherein the exterior activation sensor (2) contains at least two respective internal electrical contacts (5) which, by means of a conductive circuit (6), reach the inside of the lock and connect in parallel to the interior poles of the circuit (4a) of the power supply unit (4).
