Patent number: 8289231Abstract: A head mounted virtual image display unit is provided which is compact in size and weight, and incorporates a high performance optical system offering a clear see-through capability. A sliding light shield may be incorporated for those instances when see-through capability is not desired. A focus adjustment may be incorporated to permit the focusing of the image, for example, at a distance of approximately 18 inches to infinity. An adjustable headband may be incorporated that adapts to fit the users head. A flexible boom structure may be incorporated to facilitate fine positional adjustment of the optical assembly. A slider and ball joint mechanism may also be incorporated to facilitate positional adjustment of the optical assembly. A built-in microphone may be incorporated to enable speech input by the user.Type: GrantFiled: January 26, 2004Date of Patent: October 16, 2012Assignee: International Business Machines CorporationInventors: Russell A. Budd, Derek B. Dove, Istvan Lovas, Robert S. Olyha, Jr., Carl G. Powell

Patent number: 6792856Abstract: Disclosed is a printing apparatus, having a print surface lying in a print plane defined by an imaginary x-axis and y-axis, the print surface having an outward normal pointing in the positive direction along an imaginary z-axis, such that the x-axis, y-axis, and z-axis are substantially orthogonal to one another, a lower stamp clamp disposed adjacent to the negative-x edge of the print surface, an upper stamp clamp, moveable in two dimensions in a trajectory plane defined by the x-axis and z-axis, a stamp comprising a flexible material, the stamp having a first end attached to the lower stamp clamp and a second end attached to the upper stamp clamp, such that a cross section of the stamp parallel to the trajectory plane forms an arc extending from an origin point Q on the lower stamp clamp having (x,z) coordinates (0,0) to point E on the upper stamp clamp, this arc being described by the mathematical function &thgr;(s), where s is the curvilinear distance along the arc measured from point Q, and &thgr; is theType: GrantFiled: July 16, 2002Date of Patent: September 21, 2004Assignee: International Business Machines CorporationInventors: Shawn Anthony Hall, Ronald W.

Patent number: 6290793Abstract: A method of assembling a liquid crystal display device including a pair of substrates combined together with a sealing member and a liquid crystal interposed between the substrates, includes the steps of disposing a plurality of spacers in the area of the sealing member between the substrates, positioning a frame on an outside surface of each substrate, the frame being aligned with the sealing member, and applying pressure to each frame so that a region corresponding to a display area is substantially pressure-free and a uniform cell gap is obtained.Type: GrantFiled: June 16, 1998Date of Patent: September 18, 2001Assignee: International Business Machines CorporationInventors: Istvan Lovas, Minhua Lu, Kei-Hsiung Yang

Patent number: 4978421Abstract: The method of fabrication of a monolithic silicon membrane structure in which the membrane and its supporting framework are constructed from a single ultra thick body of silicon. The fabrication sequence includes the steps of providing a doped membrane layer on the silicon body, forming an apertured mask on the silicon body, and removal of an unwanted silicon region by mechanical grinding and chemical etching to provide a well opening in the silicon body terminating in the doped membrane.Type: GrantFiled: November 13, 1989Date of Patent: December 18, 1990Assignee: International Business Machines CorporationInventors: Ernest Bassous, Joseph M. Blum, Kevin K. Chan, Angela C. Lamberti, Constantino Lapadula, Istvan Lovas, Alan D. Wilson
