Method And Apparatus For Tuning Digital Hearing Aids
US Patent:
2003006, Apr 3, 2003
Filed:
Sep 28, 2001
Appl. No.:
09/967062
Inventors:
Rustin Allred - Plano TX, US
Mhamed Ibnabdeljalil - San Francisco CA, US
Keith Gutierrez - Plano TX, US

International Classification:
H04R025/00
US Classification:
381/314000, 381/312000
Abstract:
A method for generating digital filters for tuning a hearing aid to enhance hearing ability. Data is provided, for a range for a target response curve representative of enhanced hearing ability of sound level versus frequency. Second digital data is also generated, for an initial response curve or audiogram of an individual's hearing ability. The first digital data is compared with the second digital data and it is determined whether the initial response curve is within the tolerance range. If not, digital audio filters are iteratively generated, and the digital audio filters are applied to digital data representing received sound signals to generate third digital data to enhance hearing. Parameters of the digital audio filters are automatically optimized until the compensated response curve is within the tolerance range or a predetermined number of digital audio filters has been reached.
Video Surveillance Correlating Detected Moving Objects And Rf Signals
US Patent:
8184154, May 22, 2012
Filed:
Feb 27, 2007
Appl. No.:
11/679278
Inventors:
Leonardo W. Estevez - Rowlett TX, US
Keith G. Gutierrez - Plano TX, US
Keith G. Gutierrez - Plano TX, US
Assignee:
Texas Instruments Incorporated - Dallas TX
International Classification:
H04N 9/47, H04N 7/18
US Classification:
348142, 348143, 348149, 348152, 348154, 342 28, 396153
Abstract:
A surveillance method periodically detects an image of the area, identifies and tracks each moving object in a succession of the detected images, detects radio frequency emissions from the area and correlates an identified object with a detected radio frequency emission. The method detects events in the tracking of the moving object. The method stores corresponding data optionally including image data in non-volatile memory upon detection of a combination of an event and a corresponding radio frequency emission. The method triggers an alarm such as an audible alarm, a visual alarm, an email, a short text message or a telephone call detection of a combination of an event and a corresponding radio frequency emission.
Arc-Fault Detection
US Patent:
2012027, Nov 1, 2012
Filed:
Jul 29, 2011
Appl. No.:
13/194456
Inventors:
Keith Gordon Gutierrez - Plano TX, US
Leland Scott Swanson - McKinney TX, US
Leland Scott Swanson - McKinney TX, US
Assignee:
TEXAS INSTRUMENTS INCORPORATED - Dallas TX
International Classification:
H02H 3/08, H02H 3/16
US Classification:
361 42
Abstract:
An arc-fault circuit-interrupter includes a capability for a controller in the interrupter-circuit to be placed in a learn mode. In learn mode, the controller may change firmware to reduce the probability of false tripping or nuisance tripping. Alternatively, in learn mode, the controller may store a signature to be used as the normal signature for a dedicated load.
