Assignee:

Meyer Sound Laboratories, Incorporated - Berkeley CA

International Classification:

H04R 1/02

US Classification:

381182, 381332, 381386

Abstract:

A loudspeaker system has a plurality of relatively small transducer elements configured in a closely spaced transducer array such that their acoustic outputs combine to produce a focused beam of sound in front of the array that is substantially uniform about the beams radiation axis. The transducer array lies in a plane and has a perimeter that approximates a circle, and will have fill-factor with respect to a circle circumscribing the array of at least approximately 70%. In one variation of the loudspeaker system, the transducer array is constructed in smaller transducer array modules that are operatively fitted together to produce a larger array.

International Classification:

H04R 25/00
H04R 1/02
H04R 9/06

US Classification:

381182000, 381335000, 381186000

Abstract:

A loudspeaker system has of a plurality of relatively small, closely spaced transducer elements, the acoustic outputs of which combine to create a sound field. The transducer elements are individually controlled by a distributed input control circuit, which includes digital signal processing, to synthesize a sound field in front of the transducer elements with a characteristic beam width and direction.

Appl. No.:

8/877443

Inventors:

John D. Meyer - Berkeley CA
Alejandro Antonio Garcia Rubio - Berkeley CA

Assignee:

Meyer Sound Laboratories Incorporated - Berkeley CA

International Classification:

H05K 500

US Classification:

181152

Abstract:

A loudspeaker horn for use with an acoustical driver has a rectangular throat opening with a long dimension relative to the wavelength of the sound pressure waves generated within the high frequency range of the horn. A relatively short pre-load chamber corrects the phase of the sound pressure waves over the long dimension of the throat opening. The pre-load chamber provides control over the directivity of the horn and provides a uniform frequency response with minimal distortion.

International Classification:

B08B 104

US Classification:

15230

Abstract:

A wafer cleaning apparatus provides two opposed brushes for brushing a vertically disposed wafer in a tank which can contain a process liquid. A pressure controller adaptively controls the pressure exerted by the brushes on the wafer to compensate for brush wear. Rim driving wheels engage the wafer periphery with a porous jacket coupled to a fluid delivery system, thereby simultaneously rotating and cleaning the periphery of the wafer. The apparatus includes a fluid delivery system for separately and independently delivering a plurality of constituents of a cleaning solution to the brushes, thereby ensuring that a freshly mixed cleaning solution reaches the wafer. The tank can be filled with a process liquid through which megasonic waves provided by a transducer can propagate and impinge upon the wafer thereby enhancing the cleaning of the wafer or the brushes.

International Classification:

B01D 3500

US Classification:

210252

Abstract:

A remote filtration unit for liquid distribution systems (LDS) used for delivering ultra-pure liquids for semiconductor manufacturing processes is provided. The filtration unit includes a plurality of filtration systems enclosed in separate compartments, wherein each compartment is served by an input and an output lead line. Using quick connect/disconnect fittings, the liquid distribution system (LDS) channel is tapped at desired locations and bypass loops are inserted in the channel. A bypass loop includes an input lead line, an associated filtration unit compartment including a filtration system, and an output lead line. Using bypass loops, LDS liquid is routed into the remote filtration system, cleaned, and then channeled back into the liquid distribution system or target product or process area.

International Classification:

B62J 1/08

Abstract:

Systems and methods related to seat clamp assemblies for micro-mobility transit vehicles are disclosed. A seat post clamp assembly may include a seat clamp configured to physically secure the seat post clamp assembly to a seat post tube of the micro-mobility transit vehicle. The seat clamp may further include an adjustment handle coupled to the seat clamp via a first fastener and a second fastener. The first fastener may be inserted through a first through-hole of the seat clamp, a second through-hole of the seat clamp, and a first fastener slot disposed in the adjustment handle. The first fastener may be received in a first axle disposed in the adjustment handle. The second fastener may be inserted through a third through-hole of the seat clamp and a second fastener slot of the adjustment handle. The second fastener may be received in a second axle disposed in the adjustment handle.
