Patent number: 6829799Abstract: A seat cushion including a first and second pillar positioned specifically for receiving the ischial tuberosities of a user. The pillars relieve the pressure of the ischial tuberosity areas, but are easy and inexpensive to manufacture. In addition, the position of the pillars can be customized for a particular user. Hence, pressure reduction is accomplished only where it is needed. The invention can be used on flat cushions and on cushions with a molded shape.Type: GrantFiled: April 4, 2003Date of Patent: December 14, 2004Inventor: Paul J. Kuhn

Patent number: 6748102Abstract: A system and method for detecting alteration of a document. The invention evaluates markings in half-tone fields by ascertaining a first dot count of dots isolated from the marking in the half-tone field of the document; forming an image of the marking; superimposing the image on a blank half-tone field having the same predetermined pattern as the half-tone field of the document; ascertaining a second dot count of dots isolated from the image superimposed on the blank half-tone field; and determining whether the marking has been altered by comparing the first dot count to the second dot count. An alteration is indicated where the first dot count and second clot count are different.Type: GrantFiled: January 24, 2001Date of Patent: June 8, 2004Assignee: International Business Machines CorporationInventor: Ravi Prakash

Patent number: 6731378Abstract: The invention provides systems and a method for reducing pellicle distortion. One feature of the invention reduces distortion of a pellicle by providing an airtight mounting structure for coupling a pellicle to a mask; and a port on the mounting structure though which a pressure difference can be created between the interior portion and an exterior environment. Hence, distortion can be reduced by controlling the pressure in the interior portion between the pellicle, the pellicle mounting structure and the mask. Another feature places an aerodynamic fairing adjacent the mask to reduce aerodynamic drag and, hence, suppress turbulent air flow over the pellicle. The features can be used separately or in combination.Type: GrantFiled: February 11, 2002Date of Patent: May 4, 2004Assignee: International Business Machines CorporationInventor: Michael S. Hibbs

Patent number: 6604363Abstract: A method for matching an acoustic load and an acoustic driver in a resonant acoustic system, and the acoustic system so formed. The load and driver may be independently designed. The invention provides, inter alia, a matching volume positioned between the acoustic driver and load that is substantially greater than a stroke volume of the driver. The matching volume is sized such that, in combination with the moving mass, the characteristic stiffness of the acoustic driver and the characteristic load impedance, a resulting pressure wave produces an operating resonant frequency substantially equal to the preferred operating frequency of the load. Alternatively, or in addition thereto, a stroke volume of the acoustic driver can be adjusted.Type: GrantFiled: April 19, 2002Date of Patent: August 12, 2003Assignees: Clever Fellows Innovation Consortium, Mesoscopic DevicesInventors: John A.
