Abstract: A micro-mirror strip assembly having a plurality of two-dimensional micro-mirror structures with improved deflection and other characteristics is presented. In the micro-mirror structures, electrodes for electrostatic deflection are disposed on conical or quasi-conical entities that are machined, attached or molded into a substrate. Torsion sensors (244) are provided along the axes of rotation to control deflection of the quadrant deflection electrodes. The shielded sensor structure (240) includes a silicon layer (241), an insulating layer (242) and a metal layer (243). The structure further includes a sensor implant resistor (244) in the silicon layer (241) and a shield (245) that is applied over the sensor implant resistor (244) to stabilise sensor output and eliminate light sensitivity.

Abstract: A bonded wafer fabrication mechanism for a micro-mirror structure provides for oxidizing a device wafer instead of a handle wafer or splitting thermal oxidation processing between the device wafer and the handle wafer prior to etching. The flatness of mirrors in micro-mirror structures fabricated according to such a mechanism is substantially improved.

Abstract: The present invention provides methods, systems, and data communication networks for providing fault protection in an optical network. In one embodiment, the present invention includes a source node having an optical cross-connect switching system that has a source port card with a splitter to split an input optical signal into two similar optical signals. The two similar optical signals contain the same information. A source optical switching device switches one of the two similar optical signals to a first destination port card and onto an adjacent node and the other one of the similar optical signals to a second destination port card and onto a different adjacent node, respectively, such that the two similar optical signals are then diversely routed through the optical network. A destination node having an optical cross-connect switching system receives the two similar optical signals via first and second source port cards, respectively. The optical cross-connect switching system of the destination node includes a destination optical switching device to switch each of the two similar optical signals to a destination port card having a selector switch. The selector switch selects one of the available two similar optical signals, such that, if one of the diversely routed similar optical signals fails to reach the destination node, due to a fault in the optical network, the other one of the similar optical signals is still available. Thus, the same information is provided to the destination port card of the destination node and 1+1 optical fault protection is provided for the optical network.

Abstract: A document transport for a scanner (100) has a flexible, elongated finger (226) disposed adjacent to a document (134), and a force applied to the finger (226) urges teeth (233) on the finger (226) into contact with the document (134) which urges the document (134) along a path through the scanner (100). A piezoelectric plate (222), which applies the force to the finger (226), requires only a small amount of electrical power. To traverse the scanner (100), a document (134) may also be manually fed along a guide (272). First and second speed-sensing detectors (276a and 276b), disposed along the path traversed by the document (134), permit the scanner (100) to determine a speed at which the manually fed document (134) traverses the scanner (100). To conserve electrical energy, the scanner (100) also includes a document-presence detector (274) for activating the scanner (100) when a document (134) to be scanned is present.

Abstract: A beam (38) of electromagnetic radiation deflected by a moving mirror plate (56) of a micromachined scanner (54) produces a two dimensional ("2D") raster (132) on a scanned surface (28) of a block (34). The block (34) is transparent to electro-magnetic radiation of pre-established wavelengths. A radiation inlet-face (36) of the block (34) admits the beam (38) that then inpinges on the scanned surface (28) to exit the block (34) through a radiation outlet-face (42). After exiting the block (34), the beam (38) inpinges upon a radiation detector (142). Total internal reflection ("TIR") of the beam (38) from the scanned surface (28) at fingerprint valleys and frustration of TIR at fingerprint ridges causes the radiation detector (142) to produce a time-varying electrical signal that represents the fingerprint. The scanned surface (28) may be formed by a patch (302) of resilient material, that may be tinted to be transparent only at the pre-established wavelength of the electro-magnetic radiation.

Abstract: A compact medium scanner (100) scans a surface (132) of a medium (134) with a beam of light (106). A medium transport mechanism (202, 206) advances the surface along a medium transport path through a scanning station. A light source (104) produces a collimated beam of light (106) that impinges upon a mirror plate (112) of a micromachined torsional scanner (108). A pair of coaxially aligned torsion bars (304) support the mirror plate (112) within the torsional scanner (108). A mirror-surface drive means (306, 312) rotates the mirror plate (112) about the torsion bars (304). A single reciprocation of the mirror plate (112) by the drive means (306, 312) deflects the beam of light (106) over a fan-shaped region having a virtually fixed vertex (128) on the mirror plate (112). Scanner optics (116, 122) direct the fan-shaped region beam of light (106) onto the surface (132) of the medium (134) then present in the scanning station to thereby scan across the medium (134) with the beam of light (106).

Abstract: A micromachined, monolithic silicon vane-type flow meter (20) includes a vane (28) from which inwardly projects a hinge. The hinge is provided with torsion bars (24). The hinge supports a vane (28) for rotation about the torsion bars (24). A deflection sensing means, consisting of a torsion sensor (42) incorporated into at least one of the torsion bars (24), senses deflection of the vane (28) responsive to fluid impinging thereupon. The frame (22), the torsion bars (24) and the torsion sensor (42) are all monolithically fabricated in a semiconductor single-crystal silicon layer of a substrate.
