29/418044

Inventors:

David Levine - Valley Village CA, US

International Classification:

0601

US Classification:

D 6372

US Patent:

42377676, Dec 9, 1980

Filed:

Mar 16, 1979

Appl. No.:

6/021040

Inventors:

David H. Levine - Tarzana CA

Assignee:

Carroll Sound, Inc. - New York NY

International Classification:

G10D 1308

US Classification:

84406

Abstract:

A chime assembly is provided which includes an elongated chime support bar, a multiplicity of chimes, suspended from the support bar, and a damper bar pivotably secured to the support bar.

Appl. No.:

D/128442

Inventors:

David R. Levine - Sun Valley CA

International Classification:

1401

US Classification:

D14214

US Patent:

53926013, Feb 28, 1995

Filed:

Feb 25, 1993

Appl. No.:

3/122567

Inventors:

David A. LeVine - Los Angeles CA

International Classification:

F01N 330

US Classification:

60293

Abstract:

An exhaust system for an internal combustion engine includes a conduit in fluid communication with a combustion chamber for transferring exhaust gases from the combustion chamber. The exhaust system also includes a port disposed along the conduit for admitting supplemental air into the conduit so that the supplemental air combines with the exhaust gases and flows immediately in a direction downstream from the combustion chamber to draw the exhaust gases from the combustion chamber and to increase combustion of the exhaust gases.

International Classification:

G10L 21/055
H04R 5/04
H04R 3/04
H04R 27/00
H04L 65/75

Abstract:

Disclosed herein are new techniques carried out by a computing system for determining delays of various components of an audio system to allow for accurate correction of these delays, which may improve the audio quality of live performances for listeners who hear audio reproduced by loudspeakers at live performance venues. In one implementation the computing system, which may comprise a transmitter device and one or more receiver devices, may be configured to perform functions, including receiving a first audio signal, receiving, via an audio input interface of the receiver, a second audio signal, and determining, based on the first audio signal and the second audio signal, an audio delay that is associated with the second audio signal. The computing system may be configured to perform further functions, including based on a determined cross-correlation between a downsampled audio signal and a filtered second audio signal, determining the audio signal delay.
