Publication number: 20040007916Abstract: Minimizing the damaging effects of loud music but with minimal reduction in aesthetic quality of the music. When music presented through an audio is sampled in order to determine average frequency, music having very low average frequencies is predictably likely to be played louder than sampled music having higher average frequencies.

Publication number: 20040007946Abstract: A vibration type drive unit comprises a vibrator made of an elastic body to which an electromechanical energy conversion element is fixed and a moving element which is in contact with a surface of the vibrator so that by applying an alternating signal to the electromechanical energy conversion element. A progressive wave is generated on a surface of the vibrator to move the moving element, wherein the vibrator has a plate-like elastic body and a column-like elastic body, the electromechanical energy conversion element is fixed to a side surface of the plate-like elastic body. The column-like elastic body is formed on a central portion of a surface of the plate-like elastic body which is different from the surface to which the electromechanical energy conversion element is fixed.Type: ApplicationFiled: July 3, 2003Publication date: January 15, 2004Applicant: Canon Kabushiki KaishaInventor: Kiyoshi Nitto

Publication number: 20040007949Abstract: Disclosed is a recess-computer furniture unit that serves or both a conventional piece of furniture in one configuration, and as a computer station in a second configuration. The furniture unit includes a plurality of panels conformally integrated into the unit. These panels open to reveal a computer housing, keyboard, and flat panel monitor. In this operational configuration, a front access panel provides a support surface for the keyboard, and an upper access panel provides a mounting support for the monitor. The computer housing is discretely concealed below in a cavity created between the upper access panel and the underside of the furniture.Type: ApplicationFiled: May 22, 2003Publication date: January 15, 2004Inventor: Aaron Holt

Publication number: 20040007950Abstract: The invention relates to a switch cabinet with a rack that can be closed or is closed by at least one double-walled cabinet door, three side walls, a top wall and a bottom wall, where the side walls each consist of an internal wall and an external wall and are attached to the rack. By means of a special angling-off of the internal wall for the side walls and the back wall, a completely sealed and shielded internal space of the switch cabinet is produced, wherein the rigid attachment of the internal walls and the external walls is performed from outside the supported interior of the switch cabinet.Type: ApplicationFiled: July 12, 2002Publication date: January 15, 2004Inventors: Heiko Holighaus, Gerhard Muller, Samuel Klassen, Michael Diebel

Publication number: 20040007952Abstract: A guide rail assembly is used with a drawer to guide the movement of the drawer into and out of an article of furniture. The assembly has a supporting rail attached to a supporting surface and a pull-out rail attached to the drawer. At least one carriage is positioned between the supporting rail and the pull-out rail, and the supporting rail and the pull-out rail have stops for limiting movement of the pull-out rail and the carriage with respect to the supporting rail. A spring is loaded as the drawer is moved to the drawer-open position and actuated when the drawer is moved toward the drawer-close position. The noise associated with closing the drawer as it is pulled by the spring is controlled and suppressed by a shock absorbing device formed by a plunger and plunger-receiving cylinder.Type: ApplicationFiled: July 15, 2002Publication date: January 15, 2004Inventors: Georg Domenig, Joseph Bent Larsen

Publication number: 20040007953Abstract: A drawer guide has a longitudinally extending outer rail, a longitudinally extending inner rail nested with the outer rail and forming a longitudinally extending space therewith, and a plurality of balls engaged between the rails and allowing the inner rail to move longitudinally relative to the outer rail. A first latch member extending longitudinally in the space is carried on one of the rails. A second latch member in the space fixed to the other of the rails is latchingly engageable with the first member to prevent longitudianl displacement of the rails.Type: ApplicationFiled: June 19, 2003Publication date: January 15, 2004Applicant: Westfalia Profiltechnik GmbH & Co.
