Three Dimensional Audio Telephony

View page
US Patent:
20030044002, Mar 6, 2003
Filed:
Aug 28, 2001
Appl. No.:
09/941071
Inventors:
David Yeager - Boca Raton FL, US
Scott Isabelle - Waukegan IL, US
Karl Mueller - Sunrise FL, US
Sivakumar Muthuswamy - Plantation FL, US
Xinyu Dou - Fox River Grove IL, US
International Classification:
H04M001/00
US Classification:
379/444000
Abstract:
A method for creating spatially resolved audio signals for a listener () that are representative of one or more callers (). A digital data signal () that represents the individual caller's voice () contains an embedded tag () that is identifiable with the individual caller. The digital data signal is transmitted from a sending device at the caller's location to a receiving device () at the listener's location. At the listener's receiving device, the tag is used to associate each of the digital data signals with a head related transfer functions () that are resident in the receiving device by consulting a lookup table. The digital data streams are then convolved () with the associated head related transfer function to form binaural digital signals, which are ported to two or more acoustic transducers () to create analog audio signals that appear to emanate from different spatial locations around the listener.

Audio System With Acoustic Shock Control

US Patent:
20050181841, Aug 18, 2005
Filed:
Feb 12, 2004
Appl. No.:
10/777695
Inventors:
Xinyu Dou - Buffalo Grove IL, US
International Classification:
H04B001/38
H04M001/00
US Classification:
455575100, 455090300
Abstract:
A cellular telephone () comprises an earpiece speaker () and a loudspeaker () that share a common resonator (e.g., ). Sharing a common resonator allows the common resonator to be made large thereby improving bass response. Undesirable acoustic coupling through the common resonator is addressed by driving the earpiece speaker with a cancellation filtered version of the loudspeaker drive signal when the loudspeaker is driven.

Method And Circuit Board Panel For Circuit Board Manufacturing That Prevents Assembly-Line Delamination And Sagging

View page
US Patent:
58312188, Nov 3, 1998
Filed:
Jun 28, 1996
Appl. No.:
8/672736
Inventors:
Kai X. Hu - Cary IL
Xinyu Dou - Fox River Grove IL
Don Dillard - Mundelein IL
Gary Mui - Wheeling IL
Tom Brey - Lake In The Hills IL
Rich Dlesk - Grayslake IL
Karl Wyatt - Cary IL
Dave Roller - Libertyville IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H05K 100
US Classification:
174250
Abstract:
Board delamination during the singulation from a board panel and board sagging during front-end assembly are two biggest problems encountered in cellular manufacturing lines. The method (700) and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing. A number of slots are punched to fit into a circuit board profile. V-grooves are cut along each of the circuit board profiles through the slots and directly opposite on a top and bottom of the circuit board. Thus, optimization of the cut-outs and v-groove configurations eliminate tearing/delamination and substantially reduce sagging.

Method And Device For Providing Temperature-Stable Optical Feedback For Optical Packages

View page
US Patent:
59302763, Jul 27, 1999
Filed:
Dec 29, 1997
Appl. No.:
8/999407
Inventors:
Xinyu Dou - Fox River Grove IL
Karl Wyatt - Cary IL
Assignee:
Motrola, Inc. - Schaumburg IL
International Classification:
H01S 310
H01S 313
H01S 2715
US Classification:
372 34
Abstract:
The present invention provides a method (600) and device (200,500) for providing temperature-stable optical feedback for optical packages. The device includes an optical emitter (202,502), a first partially reflective optical element (204, 504), a second partially reflective optical element (206,506), a first optical sensing unit (208,508), a second optical sensing unit (210,510), and a feedback unit (212). The optical emitter (202,502) is responsive to an electrical input current and generates a beam of light (214). The first optical sensing unit (208,508) and the second optical sensing unit (210,510) receive diffracted portions of the beam of light (214) from the first partially reflective optical element (204, 504) and the second partially reflective optical element (206,506) respectively and generate a first feedback signal E1 and a second feedback signal E2. The feedback unit (212) utilizing the first feedback signal E1 and the second feedback signal E2 adjusts the electrical input current to the optical emitter (202,502).

Flush-Porting Method And Device For Reduction Of Wind-Induced Noise In A Microphone

View page
US Patent:
59058030, May 18, 1999
Filed:
Mar 14, 1997
Appl. No.:
8/818114
Inventors:
Xinyu Dou - Fox River Grove IL
Julio Castaneda - Coral Springs FL
Xiaohua Wu - Lake Zurich IL
David Zak - Palatine IL
Karl W. Wyatt - Cary IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04R25/00
US Classification:
381359
Abstract:
The present invention provides a method (600) and device (400) for minimizing wind-induced noise in a microphone. The device includes: a housing (412) having a recessed area shaped to accommodate a microphone transducer (410); the microphone transducer (410), situated within the recessed area such that a thin film situated over the microphone transducer is flush with/overlaying a top of the recessed area and affixed at least to the sides of the recessed area, for receiving sound; and the thin film (402) has at least one aperture (404,. . . 406) for allowing sound to impinge on the microphone transducer (410), and has a minimal thickness that maintains structural integrity.
