COMMUNICATIONS DEVICE USING ELECTROMAGNET AND ACTIVATED COMMUNICATIONS CIRCUIT

摘要

A communications device includes a processor and Radio Frequency (RF) circuitry that includes a communications module. An electromagnet is connected to the communications module and the processor. The electromagnet is configured to couple magnetically to a second communications device having a magnetic sensor and to transmit from the electromagnet to the magnetic sensor electromagnet pulses containing data regarding a wireless communications protocol. The processor and communications module are configured to establish a wireless communications connection with the second communications device.
