Patent number: 9374648Abstract: A system for providing hearing assistance having: an audio signal source; a transmission unit transmitting audio signals as data packets in a frame structure; a receiver unit for receiving audio signals from the transmission unit and associated with an ear-worn device having a power source and a hearing stimulator, and having a digital transceiver powered by the power source of the ear-worn device with a value between lower and upper limits. The transceiver listens, and optionally transmits, during part of each frame and otherwise sleeps. The receiver unit has a capacitor connected in parallel to the transceiver for supplying the transceiver with current during listening or transmission. A controlled current for controlling current flowing from the power source to the transceiver and the capacitor. The controlled current source has a DC/DC converter with an input connected to the power source and an output voltage connected to the capacitor.Type: GrantFiled: October 29, 2013Date of Patent: June 21, 2016Assignee: SONOVA AGInventors: Francois Callias, Amre El-Hoiydi, Claude Richard

Patent number: 9215535Abstract: 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.Type: GrantFiled: November 24, 2010Date of Patent: December 15, 2015Assignee: Sonova AGInventors: Yves Oesch, Claude Richard, Timothee Jost, Marc Secall, Christoph Schmid, Rainer Platz, Evert Dijkstra

Patent number: 5963155Abstract: A system and method of transforming information between UCS and EBCDIC-friendly representations comprises a two-stage transformation process using a first stage which transforms a UCS string to and from an intermediate form string, referred to as an I8-string. A second stage transforms the I8-string to and from a string in an EBCDIC-friendly representation. The two stages employ transformations which result in control characters and other selected characters being represented as single octets in the I8 and EBCDIC-friendly strings and the transformations are symmetric in both stages. The second stage can produce EBCDIC-friendly strings in one or more selected EBCDIC encodings.Type: GrantFiled: November 12, 1997Date of Patent: October 5, 1999Assignee: International Business Machines CorporationInventors: Chun-Yao Alexis Cheng, Ibrahim Ismail Meru, Claude Richard Pond, Baldev Singh Soor, Vettakkorumakankavu Sitaram Umamaheswaran
