A recently granted patent (Publication Number: US11930324B2) discloses a system comprising a hearing device and a charging device that provides a power signal to the hearing device within a specific range. The system involves establishing a primary communication channel between the hearing device and the charging device, with an authenticated pairing procedure. The charging device transmits authentication information to the hearing device through a secondary communication channel, allowing communication only over short distances, and modulates the power signal to transmit this information.

Furthermore, the system includes features such as automatically initiating the authenticated pairing procedure when the hearing device is within the charging range, detecting physical coupling between the devices, and user input for initiating the procedure. The power signal can consist of various types, and the authentication information may include a pin code, cryptographic key, or bit sequence. Additionally, the system allows for multiple hearing devices to participate in authenticated pairing procedures with the charging device, establishing primary communication channels between them. The charging device is also capable of transmitting authentication information through various signals like electrical, light, acoustical, or mechanical vibration signals, enhancing the security and efficiency of the pairing process.
