The key contains a power supply device, usually a rechargeable battery or a replaceable battery in the key, used to drive the system to work; it also includes an electronic storage and control device for storing the identification code of the lock. The software is used to set and modify the data of each key and lock. [2]
A keycard lock is a lock operated by a keycard, a flat, rectangular plastic card. The card typically, but not always, has identical dimensions to that of a credit card , that is ID-1 format . The card stores a physical or digital pattern that the door mechanism accepts before disengaging the lock.
His electrically actuated lock system could be controlled by using a handheld fob to stream infrared data. Patented in 1981 after successful submission in 1979, it worked using a "coded pulse signal generator and battery-powered infra-red radiation emitter." In some geographic areas, the system is called a PLIP system, or Plipper, after Lipschutz.
Typical public AC charger installation. Tethered (cable permanently attached) & untethered (dedicated socket outlet only) configurations. 3φ: 32A: 480V 4 EVSE rectifies AC grid & supplies DC power to EV using tethered cable with bidirectional communication – 200A: 400V DC, dedicated (IEC 62196-3) "fast DC" Current conversion handled by EVSE ...
A sliding electric gate with electric motor and backup battery in case of mains failure. Note also the Infrared obstacle sensor located on the wall to prevent the gate from closing while a vehicle or other obstacle is in the way.
Also called fail-open. In this configuration, applying electric current to the strike will cause it to lock. It operates the same as a magnetic lock would. If there is a power failure, the door opens merely by being pushed or pulled. A new trend is a strike that is quickly reversible from fail safe to fail secure (and back again if needed).

In order to provide the shear magnetic lock with the appropriate holding force, then two pins lock the armature onto the magnet itself, and ensure that the magnet locks into place.
