Abstract:
1. A hearing aid system comprising a portable module, said portable module having a portable module transceiver for transmitting and receiving electromagnetic signals, said portable module transceiver comprising a first Miller encoder for generating data for transmission, a first Miller decoder for decoding received signals and means for producing output data based on the decoded signals, said hearing aid system comprising at least one hearing aid having a hearing aid transceiver for transmitting and receiving electromagnetic signals, said hearing aid transceiver comprising a second Miller decoder for decoding received signals, means for storing programming information derived from the decoded signals, means for producing an output signal based on the decoded signals, and a second Miller encoder for generating data for transmission, the portable module transceiver and the hearing aid transceiver being adapted for transmitting and receiving Miller-encoded signals modulated according to a direct sequence spread spectrum (DSSS) scheme.
