Abstract
Described herein are systems and methods for initiating the establishment of a communication link between two devices which have complementary magnets and magnetic field sensors. When the two devices are brought together, the magnetic field from the opposing device is detected with a magnetic sensor. Based on the detection, an establishment process is initiated on each of the devices. The process may proceed and establish the communication link.
Claims23
A device comprising:
- one or more magnets configured to generate a first magnetic field;
- one or more magnetic sensors configured to detect a modulated second magnetic field;
- a radio frequency communication interface;
- at least one memory storing computer-executable instructions;
- and
- at least one processor coupled to the one or more magnetic sensors, the radio frequency communication interface, and configured to access the at least one memory and execute the computer-executable instructions to:
- detect with the magnetic sensor the second magnetic field as generated by a magnet external to the device and associated with a second device;
- demodulate the second magnetic field received by the magnetic sensor to recover received data;
- based at least in part on the detection and the received data, initiate a communication link pairing with the second device using the radio frequency communication interface;
- and
- establish a communication link with the paired second device using the radio frequency communication interface.
