A cyclic redundancy check (CRC) is added to the bit packet based on the input data. The bit packet is encoded with forward error correction. The encoded bit packet is block interleaved to create a bit stream. The bit stream is converted into symbols. Each symbol is mapped to a dual tone multi frequency (DTMF). A first audio buffer based upon the DTMF is created. The audio buffer is provided for output.

Abstract: The disclosure generally relates to a method and apparatus for energy harvest from a proximity coupling device (PCD) by a proximity integrated circuit card. In one embodiment, the PICC includes an integrated BLE. The BLE may be exclusively charged by the external magnetic field received from the PCD. The PCD may be configured to detect when the PICC is nearby and increase its duty cycle to thereby increase the magnetic field imposed on the PICC. The PICC may include circuitry to receive and convert the magnetic field to electric potential or voltage. The voltage may be store at a capacitor for BLE's usage.

Abstract: Power transmitting unit (PTU) usable with a wireless power transfer system to supply power and maintain a control signaling link to a local power receiving unit (PRU). A cross-connection circumstance between the PTU and a remote PRU is determined, where a control signaling link between the PTU and the remote PRU is established in an absence of power transmission to the remote PRU from the PTU. In response to the cross-connection circumstance, the control signaling link with the remote PRU is terminated while the supply of power and the control signaling link with the local PRU is maintained. In a related embodiment, a wrong-placement characteristic where power is transferred to a rogue local PRU in an absence of a control signaling link with that PRU, is detected. In response, the supply of power is maintained for at least a waiting period.
