  • Patent number: 9215535
    Abstract: A hearing assistance system and method for wireless RF audio signal transmission from at least one audio signal source to ear level receivers, wherein a close-to-natural hearing impression is to be achieved. At least one parameter of the RF signal as received from a transmission unit at a respective receiver unit to create left ear RF signal measurement data and right ear RF signal measurement data, respectively. The angular localization of each transmission unit is obtained by comparing, for each transmission unit, the left ear RF signal measurement data and the right ear RF signal measurement data. The audio signals are processed and distributed according to the estimated angular localization of each transmission unit in a manner so that the angular localization impression of the audio signals from each transmission unit as perceived by the user corresponds to the estimated angular localization of the respective transmission unit.

  • Publication number: 20150341973
    Abstract: A method and system of establishing a wireless network for audio data transmission with a first and second audio devices having first and second transceivers, the first audio device being an audio signal transmission unit with a user operable switch, and the first and second audio devices being assistive listening devices. Periodically the second transceiver listens for pairing information, at at least one public frequency channel; operating the switch by the user to initiate pairing at any time during operation of the first audio device; the first transceiver transmitting pairing information at said at least one public frequency channel upon operation of the switch. The second audio device automatically pairs to the first audio device upon reception of pairing information from the first transceiver. The first and second transceivers are controlled so that reception of the pairing information from the first audio device is accepted by the second audio device.

  • Patent number: 9124120
    Abstract: A wireless powering and charging system is described. Such a system comprises a radio frequency transmitter (typically a home-appliance sized unit on a desk or a shelf) and a receiver (typically a small mobile unit carried by the user). When the user is in range of the transmitter, charging or powering can take place in the mobile unit.

  • Publication number: 20150125013
    Abstract: A system for providing sound to at least one user has at least one audio signal source, a transmission unit with a digital transmitter audio data packets from the audio signal source via a wireless digital audio link; at least one receiver unit having at least one digital receiver; and a hearing stimulator responsive to audio signals from the receiver unit. The transmission unit encodes the audio signal as audio data blocks distributed onto at least two audio data packets, one of which is a low-quality packet, and one of which is a high quality packet only a low-quality version of the audio signal being retrievable from the low-quality packets, and a high-quality version of the audio signal being retrievable from both the low-quality packets and the high-quality packets. The low-quality packets and the high-quality packets are transmitted in respective dedicated slots of a multiple access protocol frame.

  • Patent number: 8693715
    Abstract: A system for providing hearing assistance to at least one user, having: at least one audio signal source (16, 20) for providing audio signals; a transmission unit (10) for wireless transmission of audio signals; at least one receiver unit (12, 14) for wireless reception of audio signals from the transmission unit; a device (42, 82) for stimulating the hearing of the user according to audio signals supplied from the at least one receiver unit. The transmission unit has both an analog transmitter (26) for applying an analog modulation scheme and a digital transmitter (28) for applying a digital modulation scheme in order to transmit the audio signals from the audio signal source (16, 20) simultaneously via an analog audio link (34) and a digital audio link (40).

  • Publication number: 20140056451
    Abstract: Method for providing sound to at least one user, involves supplying audio signals from an audio signal source to a transmission unit; compressing the audio signals to generate compressed audio data; transmitting compressed audio data from the transmission unit to at least one receiver unit; decompressing the compressed audio data to generate decompressed audio signals; and stimulating the hearing of the user(s) according to decompressed audio signals supplied from the receiver unit. During certain time periods, transmission of compressed audio data is interrupted, and instead, at least one control data block is generated by the transmission unit in such a manner that audio data transmission is replaced by control data block transmission, thereby temporarily interrupting flow of received compressed audio data, each control data block includes a marker recognized by the at least one receiver unit as a control data block and a command for control of the receiver unit.
