Adjustment Of A Hearing Aid Using A Phone
Adjustment Of A Hearing Aid Using A Phone
US Patent:
7024000, Apr 4, 2006
Filed:
Jun 7, 2000
Appl. No.:
09/589391
Inventors:
Thaddeus John Gabara - Murray Hill NJ, US
Scott Wayne McLellan - Albany Township PA, US
David L. Smith - Hummelstown PA, US

Assignee:
Agere Systems Inc. - Allentown PA
International Classification:
H04B 29/00, A61B 5/00, H04M 11/00
US Classification:
381 60, 600559, 379 52
Abstract:
A system and method for using a telephone to reconfigure or readjust the performance characteristics of a hearing aid or to check whether a user has a hearing problem. The telephone is used to generate one or more frequency tests covering the audible spectrum using a DSP contained in the phone, an external computer and/or a hearing aid. The keypad of the phone or keyboard of an attached computer is used as a feedback mechanism. The generated frequencies can be used to test the hearing of a user and the quality (or fit) of a hearing aid while being worn by the user. A local memory may be used to store the results of the tests for future reference or for transmission over the network for analysis at a later time. Once the hearing response of a user wearing the hearing aid has been measured, an updated compensation configuration (audiogram) can be downloaded into the hearing aid via an infra-red link, via a physical connection or a direct audio transmission from the telephone to the DSP in the hearing aid.

US Patent:
5619514, Apr 8, 1997
Filed:
Dec 29, 1994
Appl. No.:
8/366195
Inventors:
David L. Smith - Hummelstown PA
Assignee:
Lucent Technologies Inc. - Murray Hill NJ
International Classification:
G06F 1110, H03M 1312
US Classification:
371 43
Abstract:
A technique for efficiently utilizing memory in determining a next state accumulated cost in a communications system or a Viterbi decoder. The system includes a memory having an array of registers. A first present state accumulated cost is retrieved from a first storage register of the array. A second present state accumulated cost is retrieved from a second storage register of the array. A first next state accumulated cost is calculated based on the first present state accumulated cost. The first next state accumulated cost is stored in the first storage register of the array. An advantage of the invention is that such a technique requires less memory to calculate and store accumulated costs. The number of memory locations required is one for each individual state, which is substantially half of the memory locations required previously.
