Hearing Assistive System With Low Power Interface
US Patent:
7620429, Nov 17, 2009
Filed:
Oct 7, 2005
Appl. No.:
11/247746
Inventors:
Melvin Frerking - Norcross GA, US
George Hirvela - Carrollton GA, US
George Hirvela - Carrollton GA, US
Assignee:
AT&T Mobility II LLC - Atlanta GA
International Classification:
H04B 1/38
H04M 1/00
H04M 1/00
US Classification:
4555691, 4555561, 4555521, 455 412
Abstract:
An Interface provides for communication between a wireless communication device (WCD) and a hearing assistive device (HAD). In an exemplary embodiment the Interface includes a first short range communication module to receive a first short range communication protocol from a WCD and extract a desired audible signal and a second short range communication module to provide the audible signal to the HAD via a second short range communication protocol. The HAD may be provided with an RF module to receive a low power RF signal and provide a voice signal to the HAD user. The Interface allows the WCD device to be positioned a distance from the user's HAD, thereby decreasing interference at the HAD due to the operation of the WCD. The Interface also can be provided with a microphone to receive voice signals from the user and in turn provide them to the wireless communications device.

An onboard craft-mounted non-translating in-band only repeater system is a provided that increases the terrestrial mobile network signal levels inside the aircraft or ship to allow passengers to communicate with a terrestrial cellular communications system.
System And Method For Enhancing The Inductive Coupling Between A Hearing Aid Operating In Telecoil Mode And A Communication Device
US Patent:
7783067, Aug 24, 2010
Filed:
Aug 11, 2005
Appl. No.:
11/201557
Inventors:
Melvin Duane Frerking - Norcross GA, US
George O'Quinn Hirvela - Carrollton GA, US
George O'Quinn Hirvela - Carrollton GA, US
Assignee:
AT&T Mobility II LLC - Atlanta GA
International Classification:
H04R 25/00
US Classification:
381315, 381331
Abstract:
A method and system to optimize the relative position of an inductive field of a hearing aid compatible device and a telecoil of a hearing assistive device, are provided. A Steerable Hearing Aid Compatible Device (SHAD) has a steerable inductive field for locating an inductive field in accordance with the location of a telecoil in the hearing assistive device. A Telecoil Hearing Assistive Device (THAD) has a telecoil and telecoil orientation tag. The location of the telecoil of the THAD is determined with respect to a reference system and this telecoil location information is stored on the telecoil orientation tag as Telecoil Location Information (TLI) and provided to the SHAD. In an exemplary embodiment the telecoil orientation tag may be an RFID tag that is read by a tag reader of the SHAD. The SHAD receives the TLI and generates an inductive field in accordance with the TLI, such as a position that is parallel to the telecoil of the THAD.
Active Cancellation Hearing Assistance Device
US Patent:
7787648, Aug 31, 2010
Filed:
Aug 26, 2005
Appl. No.:
11/213471
Inventors:
Melvin Duane Frerking - Norcross GA, US
George O'Quinn Hirvela - Carrollton GA, US
Philip R. Specht - Roswell GA, US
George O'Quinn Hirvela - Carrollton GA, US
Philip R. Specht - Roswell GA, US
Assignee:
AT&T Mobility II LLC - Atlanta GA
International Classification:
H04R 25/00
US Classification:
381317, 381 716, 381 947
Abstract:
An apparatus and method for active cancellation of interference at a hearing assistive devices are presented. The apparatus includes an interference cancellation circuit for cancelling an interference component of a composite signal, and an activator circuit for enabling interference cancellation circuit. The interference cancellation circuit generates an estimated replica of the interference from an interference profile, inverts the replica to form a cancellation waveform, then adds the cancellation waveform to the composite signal to cancel the interference component. An interference profile can be provided by performing a training sequence on a composite signal to detect a repetitive signal and building a profile using its parameters, retrieving a profile stored in memory, or using an antenna to capture an RF signal. The activator circuit may enable the interference cancellation circuit when RF energy is detected, when composite signal characteristics match one or more stored profiles, or in response to user input.
Presence Activated Hearing Assistive System
US Patent:
7831055, Nov 9, 2010
Filed:
Apr 5, 2005
Appl. No.:

George Hirvela - Carrollton GA, US
Assignee:
AT&T Mobility II LLC - Atlanta GA
International Classification:
H04R 25/00
US Classification:
381312, 381315, 379 52
Abstract:
An electronic device includes a receiver, a processor, and a presence activation sensor configured to receive a signal from a user. The user signal includes a user specific performance parameter, or the user specific performance parameter may be accessed from a memory by the processor in response to the user signal. In non-enhanced mode operation, the device receives standard signals and outputs them according to standard performance parameters. In enhanced mode operation the device receives standard signals, as well as a user signal which triggers the processor to manipulate the standard signals to output unique signals according to the user specific performance parameters.
