To establish communication between a host and a client, electromagnetic field is generated across coils disposed in the devices. The magnetic field generated across the coil disposed in the host is used to power the client and to transfer data to the client. The data received by the client may, in turn, be used to configure the client. To receive data from the client, the coil disposed in the host is placed in a quiescent data recovery mode. The data to be transmitted from the client to the host generates variations in magnetic field formed across the client's coil. These variation, in turn, form variations in the magnetic field across the coil disposed in the host, and are subsequently decoded by the host to detect the data transmitted from the client. Supporting circuitry in both the host and client convert the electromagnetic variations into a stream of bits.
A device configured to establish communication via a magnetic field, said device comprising:
A device configured to establish communication via a magnetic field, said device comprising:
A system comprising a host device and a client device, wherein said host is adapted to supply power to the client device and is further adapted to configure the client device when a first coil disposed in the host device is brought into close proximity of a second coil disposed in the client device, wherein said host device comprises a coil driver coupled to the first coil and adapted to receive a clock signal and to supply a drive signal to the first coil, and wherein said client device comprises a resonant capacitor coupled to the second coil, wherein a first magnetic field is formed in said first coil during a first time period and in response to the drive signal to supply power and data to the client device, and wherein a second magnetic field is formed in said first coil during a second time period and in response to a third magnetic field generated in the second coil, wherein said third magnetic field is generated to transmit data from the client device to the host device.
A method of establishing communication between a first device and a second device, the method comprising:
