A power control system for use with an electric lock mechanism including an actuator having a coil with a particular coil impedance. The power control system comprises a power supply configured to provide an output voltage having a drive current to the actuator, a credential device powered by the power supply and configured to signal the power supply to provide the output voltage upon receiving an authorized access code, an actuator driver including a multiple-gain current-sensing circuit, and a microcontroller configured to monitor and control the power supply, credential device, actuator driver, and actuator, and determine the impedance of the coil. The microcontroller is populated by a look-up table having performance data for a plurality of coils such that the microcontroller selects a duty ratio to establish the optimum magnitude of drive current to the coil based only on the determined impedance of the coil.

A locking system is described. The locking system, includes a lock. The lock includes a semi-hard magnet and a hard magnet. The hard magnet is configured to move to open or close the lock, the lock is self-powered using near field communication (NFC), and the lock is digitally controlled using a mobile application.

An apparatus and method is disclosed for electronic locks with a selectable power off function. The electronic lock includes an electronic controller disposed within a lock housing and operable to control a state of the lock between locked and unlocked positions. An electronic actuator electrically coupled to the controller is movable between first and second positions corresponding to a locked position and an unlocked position of the lock, respectively. The electronic lock further includes at least one electrical energy storage device and a selector switch coupled to the controller to define a desired state of the lock between one of an electrically locked (EL) and an electrically unlocked (EU) state in an electric power off condition.

A patch lock assembly releasably secures a glass door to an adjacent glass panel in a locked orientation. The patch lock assembly comprises a latch adapter housing, a strike adapter housing, and first and second power supply adapter housings. The latch adapter housing may interchangeably receive one of any number of various latch mechanisms without requiring further modification of the door. The strike adapter housing may interchangeably receive one of any number of various strikes, including electric strikes, without requiring further modification of the door. Respective power supply adapter housings may be coupled to each latch adapter housing and strike adapter housing. The power supply adapters include a power source and control unit to provide the necessary power to operate the latch and strike. Various interlocking features may be incorporated in the design to resist unwanted movement of the patch lock assembly relative to the glass panel.

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.

An electro-mechanical lock is provided for a door. The lock includes inner and outer lock components mounted on opposite sides of the door and a tube extending between the inner and outer lock components, the tube being configured to receive a spindle extending through the door. The tube includes an electrical conductor integrated with the tube as a one-piece construction for transmitting electrical power and/or control signals between first and second electrical connectors at the inner and outer lock components. The tube is less fragile than conventional double tube arrangements in locks and thus can be more easily cut to length and installed at the door, improving reliability and cost effectiveness of methods of installation.

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.

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 system includes a valve (14) configured to operate a filling of a tank (11); and blocking device (15) that blocks access to the valve (14). The blocking device (15) is operated between a closing and an opening position by an actuator (20) governed by a wireless terminal (12). The wireless terminal (12) includes a transceiver (65) for sending a charging signal (WD) that includes a data signal portion (D) and a supply portion (W) carrying energy via electromagnetic induction, in particular a WPC (Wireless Power Consortium) signal. The blocking device (15) is configured for receiving electrical energy from the supply portion (W) to operate the actuator (20). The blocking device (15) also includes a control module (70) enabling operation of the actuator (20) according to the data signal portion (D) exchanged with a corresponding control module (60) of the wireless terminal (12).

A lock portable charging apparatus includes a case defining an interior area that is enclosed and a locking device situated in the case. A shackle assembly is operatively coupled to the locking mechanism and is functional to selectively secure the case to a support structure. The case defines a key inlet for receiving a key in to operate the lock mechanism. A battery, processor, and memory storing programming are situated in the case. A primary and auxiliary USB port are positioned on the case and electrically connected to the battery for receiving AC power to recharge the battery and share battery power with other electronic devices, respectively. A GPS module is in the case for determining a global location of the case. A solar cell is included to provide electrical current to the battery. Programming is included to locate a mobile phone associated with the case.
