摘要： One embodiment of the present invention provides a smart lock-and-key system. The smart lock-and-key system can include a smart lock corresponding to a lock identifier and a smart key capable of locking and unlocking the smart lock. The smart key can include a first communication interface for communicating with the smart lock and a second communication interface for communicating with a mobile computing device. The smart key can be configured to obtain the lock identifier and receive, from the mobile computing device, an operation command based on the obtained lock identifier.

摘要： One embodiment provides an electrical key for locking and unlocking an electrical lock. The electrical key includes an energy-transfer unit that includes a magnetic core and a coil wrapped around the magnetic core, a pulse generator configured to generate a first pulse sequence including alternating pulse on and pulse off cycles and a second pulse sequence comprising a continuous pulse train, and a modulator driver configured to modulate a voltage or current on the coil using the generated first or second pulse sequence, a measurement module configured to measure a current or voltage on the coil excited by the modulated voltage or current, respectively, a key-position determination module configured to determine a relative position between the electrical key and the electrical lock based on the measured current or voltage, and a communication interface for communicating with the electrical lock to facilitate the locking and unlocking of the electrical lock.
