An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry.

Capacitive data transfer in an electronic lock and key assembly

A locking device comprises a key that comprises a key power coil and a key data coil and an electronically-actuatable lock comprising a lock power coil and a lock data coil. The key power coil and the lock power coil are coaxial and at least partially overlapping one another when the key engages the lock. The key data coil lies in a first plane and the lock data coil lies in a second plane. The first plane and the second plane are substantially parallel to one another.

Electronic lock and key assembly

In one embodiment, a pharmaceutical cabinet comprises sensors positioned within the frame and door of the cabinet, and the sensors are arranged in a predetermined orientation when the door is closed and a lock is actuated. The sensors are configured to communicate with one another when brought into the predetermined orientation to confirm that the door is closed and the lock is actuated. One or both of the sensors may transmit an identifier to the other sensor, and the communication between the sensors may be encoded. The cabinet also includes a sensor on the lock that indicates if the lock is engaged. The cabinet may generate a record of the times the sensors are moved into or out of communication and the times that the lock is engaged.

System and method of monitoring the door of a secure cabinet for holding pharmaceutical products

An electronic lock may include a locking mechanism and a cartridge having a body portion and one or more extension receiving portions that may receive the locking mechanism. The lock may also include a first coil positioned around the cartridge, a core disposed within the cartridge and substantially within the first coil, and a second coil positioned around the cartridge. The second coil may be spaced from the first coil. In addition, a first sliding barrier may be disposed within the cartridge, which barrier may be selectively in communication with the locking mechanism. A control circuit may be included in the lock, which may energize the first and second coils to cause the first sliding barrier to move from a first position magnetically attracted to the core to a second position magnetically attracted to the second coil and thereby allow actuation of the locking mechanism.
