Zusammenfassung: | Devices, systems and methods for magnetic field coupling, as described herein, optimize magnetic coupling between transducers generating and detecting quasistatic magnetic fields by translating the generated and detected magnetic fields into a common frame of reference, such as the Earth's gravitational field. In general, a receiving device has knowledge of the strength and direction of a quasistatic magnetic field generated by a transmitting device, which allows the generated magnetic field to be measured and interpreted by the receiving device in the context of the common frame of reference. Such devices, systems, and methods may use magnetic coupling, for example, for proximity detection and/or for communication between devices. Magnetic coupling may be used for proximity detection, for example, by detecting a magnetic field having a defined magnetic field range and/or by measuring magnetic field strength and/or direction and determining distance and/or location. |
