Significant advances in semiconductor microelectronics technologies have resulted in greatly enhanced chip performance. Systems studies have continuously shown that on-board interconnects between chips are the bottleneck in achieving board level performance that is comparable with this chip performance. This invention provides a multiple-layer photonic-electronic circuit board family that solves this interconnect performance problem. Multiple layers of patterned optical channel waveguides and patterned electrical conductors co-exist in a single circuit board structure, with optical vias to transport light between different photonics layers and electrical vias to transport electrical signals and power between different electronics layers. An all-lithographic fabrication technology is used to build the entire board structure with mutually compatible planar processing steps. Novel techniques are used to produce channel optical waveguides connected to in-plane 45 degree turning mirrors and channel optical waveguides connected to optical vias with out-of-plane 45 degree turning mirrors. The mirrors can have either total internal reflection or metallized facets.

Economical production of configured, laser-drilled, high-precision, ultra-miniature multiple-via-hole patterns is accomplished by multiplexing the homogenized, shaped, nearly-collimated output of one or more high-power excimer lasers into a set of beamlines, differently configured at different depths through the thickness of the substrate. A substrate delivery subsystem provides a continuous supply of film substrate strips or segments, which may be blanks or intermediates. Various stencils in a mask provide a cup-shaped partial hole, which is subsequently provided with a mating stem hole. Each stem portion of each hole is laser-drilled into the bottom of the cup portion from either above or below to form a via-hole with a desired configuration, such as stem-glass (or cup/funnel), as desired for multi-micro-via-hole arrays for filtering or for forming clog-resistant aerosol nozzles. Parameter changes of one or both of duration and focus may substitute for changes of mask to effect the changes in cup configuration as contrasted to stem configuration.

Pixel-level monitoring and reconfiguring of both text inter-word spacing and individual character widths minimizes undesirable moire&prime; channels and moire&prime;-glyphs, and more particularly relates to operator-selected automatic intra-word space manipulation and automatic intra-character width manipulation to achieve a pleasing overall page effect with maximized freedom from moire&prime;-maze and moire&prime;-glyph visual effects, both in proportional spaced fonts and fixed-character-width fonts. Selective scrolling may be by black-spot instead of actual characters, to make the white moire&prime;-effects stand out more clearly. The typesetter may alternate positive and negative, which is another way to emphasize the moire&prime;-effects. A further sub-variant, called &ldquo;blush,&rdquo; causes graying of spaces which are so surrounded by characters that they cannot participate in moire&prime;-effects. This emphasizes the actual moir&eacute;-effects. The typesetter may &ldquo;unselect,&rdquo; by pointing a cursor at a moire&prime;-effect and key &plus; or &minus; to accept the particular moire&prime;-effect as benign, or to proceed with an amelioration procedure.

This single-actuator-and-cam, remotely adjustable, exterior vehicle rear-view mirror provides the driver with glare-free viewing toward the rear of the vehicle, by switching between a high-reflectivity position and a low-reflectivity position at the same view adjustment. The exterior rear-view mirrors are repositioned with only a single motor working with a rotary cam to scan all possible mirror positions. The single-motor mechanism increases the reliability of the mirror system. The single motor accomplishes both the directional alignment and the day/night reflectivity adjustment of the mirror by use of a cam which has positions for all predicted view positions, with two reflectivity positions for each view. This invention works equally well with flat wedge mirrors and wide-angle convex wedge mirrors. Since each position is unique, each directional/reflectivity position can be assigned a set of digital coordinates which can be stored for each vehicle driver and each glare condition, for an initial setting which can be easily, or even automatically, adjusted for changes as the driver desires. Customizing features include manual and vehicle driver identification controlled override, start-up reset, and glare threshold setting.

Economical production of laser-drilled high-precision, ultra-miniature multiple-via-hole patterns is accomplished by multiplexing the homogenized, shaped, nearly-collimated output of a high-power excimer laser into a modular set of condenser lens/mask/projection lens beamlines. A substrate delivery subsystem provides a continuous supply of film substrate segments as blanks during production. Functional modularization permits the building and easy retooling of a hard-tooling multiple-beamline system powered by a high-power laser. Vertical modularization permits the building of a single-beamline soft-tooling pilot system, which may be used to demonstrate a production technique, or may be used for short production runs, and which may later be incremented with additional vertical subassemblies for additional beamlines. Multiplexing of the laser output beam into the set of beamlines is accomplished by an illumination module, which may be implemented as a single 100%-reflective fold mirror for a single-beamline pilot system, and can also be implemented as a single-block echelon mirror, or implemented as a multi-beamsplitter set of decreasing-reflectivity mirrors as mirror position approaches the beam source. The resulting product is a film blank with a via-pattern of precise micro-vias, useful as an aerosol nozzle or filter.

An energy saving skylight cover system operates selectively in summer and winter to optimize transfer of the sun's radiation through the skylight into an interior space. The skylight cover system comprises optical transmission modifying panels and radiation scuppers that make its functional characteristics responsive to the sun's incidence angle. In summer mode, with high average inclination of the sun, the skylight cover system absorbs or reflects back the undesirable solar heat. In winter mode, the skylight cover system permits majority of the sun's rays to enter the interior space, permitting desirable solar heat gain. The determination of rejecting or accepting solar heat gain is made by the skylight cover system according to a designed-in characteristic angle. The characteristic angle is a function of the orientation of the skylight and the roof, and the geographical location of the building. For manufacturing cost-effectiveness, a finite set of skylight cover pane designs with predetermined characteristic angles is selected. The radiation modifying panels consist of one or more diffraction gratings, with additional spectrally selective and angle-selective coatings and materials for selective rejection and transmission of ultraviolet, infrared and visible portions of the solar radiation to provide maximum energy efficiency combined with optimum thermal and optical comfort of the building occupants.

This invention describes a surface profilometry system which measures the surface topography of a sample on a sub-nanometer scale. The surface profile is determined through measurement of the change in distance between two mirrors of a multi-pass resonant cavity that is referenced to a frequency stabilized laser source. The contact stylus is in contact with the sample as it is translated along the plane to be measured. As the stylus traverses the sample, it is vertically deflected and transfers the motion directly to one of the mirrors of a multi-pass resonant cavity. The cavity is referenced to a frequency stabilized laser source that is synchronized with the resonant modes of the multi-pass cavity. Very small sub-nanometer deviations of the cavity can be detected by monitoring the laser beam incident on the multi-pass cavity. There are two embodiments by which the cavity length changes can be measured. The first embodiment involves adding variable frequency sidebands onto the stabilized laser through the use of an optical modulator. As the resonant cavity changes length due to the motion of the stylus, the modulation frequency is varied so that the sideband is kept on resonance with the cavity mode. The second embodiment involves monitoring the direct output of the stabilized laser beam after reflection from the resonant cavity. A position actuator adjusts the length of the cavity to maintain the resonance condition between the cavity mode and the stabilized laser beam.
