摘要： 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.

摘要： 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 the angle between the print plane and an imaginary line, the imaginary line being tangent to the cross section of the stamp at s, and wherein, during a print operation, the upper stamp clamp is moved in a trajectory comprising a plurality of xz positions of the upper clamp stamp that blend into a substantially continuous motion, the trajectory being effective in laying the stamp down smoothly and flat upon the print surface in a manner such that a moving contact front between the stamp and the print surface is created, the contact front being disposed substantially along a line characterized by a contact-front coordinate s0 x0 that increases as the trajectory progresses, the trajectory also being effective in causing the curvature ⅆ θ ⅆ s of the stamp at or near the contact front to be substantially constant throughout the motion. The preferred embodiment also has either or both of two additional systems that move along the x axis in coordination with the motion of the upper stamp clamp: a print-force-application system effective in pressing the stamp against the print surface, and a stamp control system for helping to control the curvature of the stamp near the contact front.

摘要： 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. The head mounted virtual image display unit may be used comfortably in conjunction with eye or safety glasses, and provides a useful image to the user without blocking his view of the surrounding environment. The unit is designed to have a pleasing appearance so as to greatly enhance user acceptability.
