A multipoint lock is described. The multipoint lock includes a main latch. The main latch has a latched position where the main latch is configured to extend a first distance from an unhinged edge of a door panel. The main latch is configured to be retractable toward the unhinged edge of the door panel by rotation of a latch drive hub in each of a clockwise direction and a counterclockwise direction relative to a first side of the door panel. The multipoint lock also includes at least one auxiliary latch and a deadbolt drive hub. Rotation of the deadbolt drive hub substantially simultaneously actuates the main latch and the at least one auxiliary latch.

What is presented is a power-transfer system that provides resonant inductive power from a first object to a second object, which is adjacent to the first object. The system includes a first transformer portion that is positioned on the first object and having a first core portion. The first core portion includes a transmit unit configured to transfer an electromagnetic field to the second transformer portion. The first core portion also includes first circuitry that allows the transmit unit to transfer the electromagnetic field. The second transformer portion is positioned on the second object and has a second core portion. The second core portion includes a receiver unit configured to receive the electromagnetic field. The second core portion also includes second circuitry that allows the transmit unit to transfer the electromagnetic field.

A hinged object, such as a door, window, gate, lid, etc., comprises a first hinge, a second hinge, and an electromechanical locking device mounted on or in the hinged object. A first electrical wire is embedded in the hinged object that couples the electromechanical locking device to the first hinge, the first hinge to couple to a low-voltage power source to supply low-voltage electrical current to the electromechanical locking device via the first electrical wire. A second wire is embedded in the hinged object that couples the electromechanical locking device to the second hinge, the second hinge to couple to the low-voltage power supply to return low-voltage electrical current from the electromechanical locking device to the low-voltage power supply via the second electrical wire.

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.

An electronic lock structure using a wireless charging device contains a power supply unit and an electronic lock unit. The power supply unit includes a variable-frequency drive and an AC/DC transformer. The electronic lock unit includes a battery and a rectification circuit, wherein the rectification circuit electrically outputs power of alternative current by way of a power receiving coil. When the power receiving coil is close to the power output coil, the power supply outputs the power to the electronic lock unit by using magnetic flux and to supply the power to the battery, thus charging the battery. When the power receiving coil is away from the power output coil, the power output coil does not conduct the power to the power receiving coil.
