摘要： A door security system comprises a door, and a handle assembly attached to the door. The handle assembly includes a lock mechanism, a handle, and an escutcheon. The lock mechanism has an unlocked state and a locked state for securing access to the door, and the handle is rotatably supported by the handle assembly as a means of access through the door when the lock mechanism is in the unlocked state. At least one of the handle and the escutcheon acts as an antenna capable of wirelessly receiving and transmitting radio frequency signals and capable of communicating with the lock mechanism to switch the lock mechanism between the unlocked and locked state.

摘要： An exemplary security device includes a reader configured to read information stored on a credential device. The reader enters a sleep mode when not reading a credential device. A wake-up module includes an inductively coupled resonant circuit. The wake-up module is configured to detect a credential device near the reader if the credential device has a resonant frequency corresponding to a frequency of an electromagnetic field of the inductively coupled resonant circuit that is controlled by a stable oscillator. The wake-up module is configured to provide an indication to wake-up the reader from the sleep mode responsive to detecting a change in power of the electromagnetic field caused by the credential device.

摘要： A power management circuit decreases power consumption in an electronic door lock. The power management circuit includes an ON/OFF circuit, a load switch circuit and a electronic door lock circuit. The ON/OFF circuit generates an initial enable signal in response to a detected keycard that places the load switch circuit in an enabled state. When enabled, the load switch circuit provides dc power to the electronic door lock circuit that allows the electronic door lock circuit to receive identification input from the detected keycard and determine whether an output should be generated to actuate the door lock mechanism. Having completed the keycard detection operation, the electronic door lock circuit generates a self turn-off signal that is provided as feedback to the ON/OFF circuit to disable the load switch circuit. When disabled, the load switch circuit prevents any power from being provided to the electronic door lock circuit and thereby conserves energy otherwise consumed by the electronic door lock in times between activations.
