摘要： A fiber optic switch includes a fiber optic switching module that receives and fixes ends of optical fibers. The module includes numerous reflective light beam deflectors which may be selected as pairs for coupling a beam of light between a pair of optical fibers. The module also produces orientation signals from each deflector which indicate its orientation. A portcard included in the switch supplies drive signals to the module for orienting at least one deflector. The portcard also receives the orientation signals produced by that deflector together with coordinates that specify an orientation for the deflector. The portcard compares the received coordinates with the orientation signals received from the deflector and adjusts the drive signals supplied to the module to reduce any difference between the received coordinates and the orientation signals. The switch also employs optical alignment to precisely orient pairs of deflectors coupling a beam of light between optical fibers.

摘要： A method for fabricating an integrated, micromachined structure, such as a torsional scanner, that includes a reference member, such as a frame, a pair of torsion hinges, and a dynamic member that is coupled to the reference member by the torsion hinges. The method includes providing a wafer that has been formed from silicon material, and that has both a frontside and a backside. A membrane is formed in the wafer by etching a cavity in the silicon material from the backside of the wafer. The method also includes establishing a pattern that defines the mirror surface and the torsion hinges on the frontside of the wafer at the membrane formed therein. The frontside of the wafer is processed to form therein the dynamic member and the torsion hinges that support the dynamic member for rotation about the axis.

摘要： 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.

摘要： A method for operating a monolithic, integrated, micromachined structure that includes a reference member and one or more dynamic members. Each dynamic member is supported from the reference member, either directly or indirectly, by torsion hinges. Supported in this way, each dynamic member exhibits a plurality of vibrational modes. Preferably, the structure is micromachined to establishes specified relationships between various pairs of vibrational modes. The method also includes applying force to each dynamic member that urges the member to rotate out of a rest position to a fixed particular angle.

摘要： Two torsion bars project from a reference member to support at least one plate or frame-shaped first dynamic member for rotation about an axis of the torsion bars. In one embodiment, a frame-shaped first dynamic member and a second pair of torsion bars, oriented non-parallel to the first torsion bars, support a second dynamic member for rotation about an axis that is collinear with the second pair of torsion bars. The vibrational frequency of the principal torsional vibrational mode of the dynamic members are respectively lower by at least 20% than the vibrational frequency of any other vibrational mode thereof. Either an electrostatic or electromagnetic drive means imparts rotary motion to the dynamic members about the collinear torsion bar axis(es). The reference member, the torsion bars and the dynamic member(s) are all monolithically fabricated from a stress-free semiconductor layer of a silicon substrate.
