Abstract: 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.

Abstract: Provided are a method and apparatus for dynamically controlling electrical loads, a storage medium and an electronic apparatus. The method includes that: a current capacity balance of a user sub-region is acquired from an intelligent electricity monitoring and metering terminal through a mobile terminal; when the current capacity balance is smaller than a load power of an electric consumption device to be started in the user sub-region, a regional coordination control apparatus or a server is requested through the mobile terminal to adjust and increase a capacity allocated for the user sub-region, such that a capacity balance will be greater than or equal to the load power; and whether to allow to start the electric consumption device is determined according to a decision replied by the regional coordination control apparatus or the server.

Abstract: One embodiment of the present invention provides a smart lock-and-key system.
