Abstract: Apparatus for masking (center and peripheral) the microscope condenser lens to simultaneously maximize resolution, contrast and depth of field utilizing, at a conjugate plane of the aperture plane where an image of the rear aperture of the condenser lens has been created, a plurality of light sources to illuminate two or more of the faces of a multi-faced mirror in the shape of a pyramid which moves relative to the light sources to vary the amount of center masking continuously over a range including zero while directing multiple oblique beams of light onto the objective lens including such apparatus for connection to the illumination port of a light microscope in place of a standard light source.

Abstract: An illumination system and method for 3-D viewing and increasing resolution, sharpness, depth of field, and perception of depth for a light microscope including an objective lens having an optical axis, wherein one or more illuminating light beams are focused onto the specimen via paths that include the objective lens and are not coincident with the objective lens optical axis, and reflection beams follow paths that include the objective lens.

Abstract: A reflector formed on a base with a thick (0.5 to 2.0 microns) layer of non-porous oxide underlying an aluminum vacuum deposited layer which supports a pair of quarter wavelength reflectance-enhancing layers.

Abstract: A method and apparatus are disclosed for laser treatment of surfaces, such as tissue. In a preferred embodiment, the invention employs a unique reflective optical delivery system which produces an improved beam intensity cross-section which reduces thermal injury, increases the precision of the tissue interaction and allows the creation of craters with decreased sizes. Reflective optics provide precise, single-layer vaporization at low power levels without thermal injury to the underlying papillary dermis. Movable optical elements focus and direct the laser beam in a scanning pattern to treat a large area of the surface.

Abstract: A condenser for a transmitted light microscope with built-in 3-D filters and stereo pair photo apertures that permit a standard 2-D microscope, high power as well as low power, to produce a variety of high quality 3-D images and photos.

Abstract: A latch mechanism includes a housing containing a force transfer member. At one end of the force transfer member, a first cam mechanism is provided which is intended to be rotated by an actuator handle. At the other end of the force transfer member, a second cam mechanism is pivotably mounted to the housing and is pivoted through movements of the force transfer member responsive to rotations of the first Cam mechanism. The second cam mechanism is coupled to a latch bolt so that rotations of the first cam mechanism will result in movements of the latch bolt. The improved latch mechanism is designed to permit complete retraction of the latch bolt through rotation of the first cam mechanism by less than one-twelfth of a revolution, in either direction of rotation.

Abstract: Methods and apparatus for changing sets of configured operational features in a utility program based upon changing screen images in a currently active application program.

Abstract: Methods and apparatus for center masking a condenser lens of a transmitted light microscope to simultaneously maximize resolution, contrast and depth of field utilizing at a conjugate plane of the aperture plane where an image of the rear aperture of the condenser lens has been created, a plurality of light sources to illuminate two or more of the faces of a multi-face mirror in the shape of a pyramid which moves relative to the light sources to vary the amount of center masking continuously over a range including zero while directing multiple oblique beams of light onto the objective lens.

Abstract: A computer readable memory operable with a computer having a display screen to cause the computer to store problems and solutions and permit various different kinds of hints and suggestions to be accessed during the solution of the problems.

Abstract: An illumination system increasing resolution, sharpness, depth of field, and perception of depth for a transmitted light microscope including a condenser lens having an optical axis, objective lens having an optical axis, wherein a plurality of separate light beams pass through the condenser lens along paths that are not coincident with the condenser lens optical axis and which follow exit paths from the condenser lens which pass through the objective lens and which are at an oblique angle to the optical axis of the objective lens.

Abstract: An illumination system increasing resolution, sharpness, depth of field, and real time 3D perception of depth for a transmitted light microscope including an objective lens having an optical axis, wherein a plurality of separate light beams passing through a specimen to the objective lens along paths that are oblique to the optical axis of the objective lens. Fiber optic light guides can be used to initiate a light beams that follow the above described paths.

Abstract: An illumination system and method for releasing resolution, sharpness, depth of field, and perception of depth for a light microscope including an objective lens having an optical axis, wherein one or more illuminating light beams are directed onto the specimen via paths that include the objective lens and are not coincident with the objective lens optical axis, and reflection beams include the objective lens.

Abstract: A light microscope with lenses projecting the rear aperture of an objective lens at a location remote from the objective lens enhancing high power stereoscopic viewing and photographing with a binocular (two eyepiece) viewing system and when combined with an iris in close proximity to the projected image of the rear aperture of the objective lens, controls flare.

Abstract: Embossing apparatus for artists and hobbyist including a stencil component having one or more cut-outs of designs to be embossed into a piece of paper and a guide component with identical cut-outs and alignment means for aligning like cut-outs of the two components when a piece of paper to be embossed overlays the stencil component.

Abstract: A self terminating phone plug having a switch armature disposed between the inner signal carrying shaft and the outer ground shaft wherein the armature is biased to electrically ground the inner shaft except when an actuator carried by the armature and protruding through the outer shaft is urged inward toward the inner shaft, as when the plug is inserted into a jack, in which case the armature disconnects from the outer shaft and ungrounds the inner shaft.

Abstract: A computer keyboard having an output port through which scan codes are directed to a computer CPU over a cable, the keyboard of the kind having a touch activated membrane switch onto which one of a plurality of key layout overlays can be installed. Each of a plurality of different stored data tables is operable when selected to determine the particular scan code that is directed through the keyboard output port over the cable in response to a membrane switch being activated. Each overlay being coded in a way that can be read by an overlay code identification device which automatically operates in response to a coded key layout overlay being installed onto the keyboard to read the overlay code, which is then used by a data table selector to select a particular data table for use with the installed overlay.
