Publication number: 20240029755Abstract: Processes, methods, systems, and devices are disclosed for intelligently detecting speech or in audio signals and smoothly transitioning to mode that enables a user to better understand the speech. For example, aspects of the present disclosure provide method for processing and producing audio signals. During playback of an audio signal, the method analyzes content of the audio signal prior to the playback of the content to determine whether one or more predefined conditions are met to indicate that the content includes speech. In response to determining the one or more predefined conditions are met, the method automatically applies to the audio signal a first playback equalization configured to enhance the speech within the content. In response to determining the one or more predefined conditions are not met, the method comprises applying to the audio signal no playback equalization or a second playback equalization different from the first playback equalization.Type: ApplicationFiled: July 19, 2022Publication date: January 25, 2024Inventors: Elio Dante QUERZE, III, Shuo ZHANG, Isaac Keir JULIEN, Yang LIU, Miriam ISRAELOWITZ, Stoyan I.

Patent number: 10857638Abstract: An adjustable clamp for the retention of a vice or work piece onto a slotted worktable. The clamp has a raised rear foot that both spans the standard width of a slot in a slotted worktable regardless of the angle the clamp is secured to the worktable, and generates an increased gripping force at both contact points of the clamp. Its nose accommodates a cylindrical pin recess to accommodate a cylindrical pin to allow the vice to clamp to a vice with a raised peripheral lip. The 30 degree beveled front edge allows the clamp a substantial planar contact surface with the vice or work piece, enhancing stability.Type: GrantFiled: August 16, 2017Date of Patent: December 8, 2020Inventor: Michael W Stark

Patent number: 8553894Abstract: An three-way audio system that uses directional arrays for radiating mid-frequency acoustic energy and passive directional devices to radiate the high frequencies. the system includes a left channel, a right channel, and a center channel. A crossover network separates the left channel and the right channel into low frequency content, midrange frequency content, and high frequency content. An omnidirectional acoustical device radiates acoustic energy corresponding to the low frequency content of the combined left channel, right channel and center channel. A first directional array, comprising signal processing circuitry and more than one acoustic driver, radiates acoustic energy corresponding to the midrange content of one of the left channel and right channel signal so that more acoustic energy corresponding to the midrange content of one of the left channel signal and the right channel signal is radiated laterally than in other directions.Type: GrantFiled: August 12, 2010Date of Patent: October 8, 2013Assignee: Bose CorporationInventors: William Berardi, Michael Dublin, Eric S.
