A key unit includes: a first communication module; a second communication module; an authentication unit configured to perform authentication using authentication information when an operation request including the authentication information has been received via the first communication module; and a control unit configured to perform locking and unlocking with a key in response to the operation request when the authentication using the authentication information has succeeded and to transmit a control signal for performing an operation other than the locking and unlocking with the key to the control device via the second communication module after the authentication.

An electronic locking device can be configured to become active from a low power state, receive physical input to unlock, and provide access to a replaceable power supply. An electronic locking device can use a combination of physical input and discovery of an authorized mobile device to enable transition from a locked state to an unlocked state. Authorization can be internally stored or externally obtained through a service. An electronic locking device can match a series of physical interactions to a series of stored interactions to enable transition from a locked state to an unlocked state, when an authorized device is unavailable. An electronic locking device can provide access to a replaceable power supply when a latch is released.

A door opens for an authenticated user by being tapped by a communication device. A physical access control system actuates upon receiving a wireless request triggered by a pattern of indicia in the vicinity of a portal. A hand-held communication device transmits a portal access control signal when it recognizes a pattern of bursts in signal amplitude. A mobile device has a sensor package, communication circuits, and a processor. Upon determining proximity to a controlled portal, the sensor package enables a pattern recognition circuit. Upon receiving a success indicia from the pattern recognition circuit, the communication circuits authenticate with the controlled portal, e.g. causing a door to open. A sensor package may be enabled by accelerations from bumping the device; tapping the device against a door, wall, or table. A pattern may be related to a number, or a sequence, or combination of slows, pauses, and quicks, or a single acceleration.

Systems and methods for time-bound homogeneous consecutive events triggering a procedure in an access control host system are provided. Some methods can include receiving notifications of a plurality of events occurring in an access control system, identifying an event trigger when at least some of the plurality of events are homogeneous, time-bound, and consecutive, and, responsive to identifying the event trigger, transmitting an instruction to at least one device in the access control system for execution of a procedure associated with the event trigger.

An apparatus and method for controlling opening and closing of a vehicle door are provided. The apparatus includes a driving unit that opens and closes a door a controller that operates the driving unit. Additionally, an acoustic wave processing unit receives and analyzes an acoustic wave signal generated by force exerted onto the door to generate a control signal for opening or closing of the door. The controller receives the control signal to thus operate the driving unit. Further, the acoustic wave processing unit includes an acoustic wave sensor disposed inside of the door and receives the acoustic wave signal, and an MCU that analyzes a signal output from the acoustic wave sensor to generate the control signal.

An intelligent door lock system includes a drive shaft of a lock device and a circuit coupled to an engine with a memory. A vibration/tapping sensing device is configured to be coupled to the lock device to lock or unlock the door. A device converts energy into mechanical energy coupled to the drive shaft.
