Abstract
An embodiment of an electronic access control system includes an electronic access apparatus, an electronic lock, and an access control administration program. The electronic access apparatus provides a wireless power signal and a wireless digital data signal to the electronic lock. The wireless power signal can be the only source of power used by the electronic lock to actuate an electronic lock mechanism. In some embodiments, the lock mechanism includes a piezoelectric latch.
Claims20
A handheld electronic apparatus for use with an electronic lock, the handheld electronic apparatus comprising:
- a battery configured to supply energy to components of the electronic apparatus;
- a physical storage medium storing at least one identifier;
- an electromagnetic radiation source;
- a signal processing circuit connected to the electromagnetic radiation source;
- at least one processor configured with computer executable instructions to cause the electromagnetic radiation source to:
- transmit a wireless digital data signal to an electromagnetic radiation receiver, the digital data signal comprising the at least one identifier,
- transmit a wireless power signal to the electronic lock to provide power to the electronic lock sufficient to actuate a lock mechanism within the electronic lock between a locked state and an unlocked state, and
- wherein the wireless power signal delivers less than or equal to 100 millijoules of electric energy to the electronic lock over a time period of less than or equal to 5 seconds;
- wherein a lock microcontroller is configured to control operation of the lock mechanism based at least in part on the wireless digital data signal received from the electronic apparatus,
- wherein the lock mechanism is capable of actuating between the locked state and the unlocked state using the electric energy supplied by the wireless power signal, and
- wherein the handheld electronic apparatus can be greater than 0.5 centimeters from the electronic lock when transmitting the wireless digital data signal and the wireless power signal to actuate the lock mechanism.
