    • A monolithically fabricated micromachined structure (52) couples a reference frame (56) to a dynamic plate (58) or second frame for rotation of the plate (58) or second frame with respect to the reference frame (56). Performance of torsional oscillators or scanners (52) benefits greatly by coupling the frame (56) to the plate (58) or second frame with torsional flexure hinges (56) rather than torsion bars (54). Appendages (122), tethers (142) or an improved drive circuit enhance electrostatic drive stability of torsional oscillators (52). Wide and thin torsional flexure hinges (96) and isotopically pure silicon enhance thermal conductivity between the plate (58) and the frame (56). Dampening material bridging slots (232) adjacent to torsional flexure hinges (96) drastically reduce the dynamic member's Q. A widened section (252) of narrow torsional flexure hinges (96) permit inclusion of a torsion sensor (108). A dynamic member (58) that includes an actuator portion (302) performs light beam switching. Reflective coatings (76), wire grid polarizers (362), photo-detectors (372) and Fresnel lenses (376) enhance optical performance of the torsional scanners (58).
    • 单片制造的微加工结构(52)将参考框架(56)耦合到动态板(58)或第二框架,用于相对于参考框架(56)转动板(58)或第二框架。 扭转振荡器或扫描仪(52)的性能通过将框架(56)与扭转挠性铰链(56)而不是扭杆(54)联接到板(58)或第二框架而受益匪浅。 附件(122),系绳(142)或改进的驱动电路增强了扭转振荡器(52)的静电驱动稳定性。 宽和薄的扭转弯曲铰链(96)和同位素纯硅增强了板(58)和框架(56)之间的热导率。 与扭转弯曲铰链(96)相邻的阻尼材料桥接槽(232)大大减小了动态构件的Q.窄扭转挠曲铰链(96)的加宽部分(252)允许包括扭转传感器(108)。 包括致动器部分(302)的动态构件(58)执行光束切换。 反射涂层(76),线栅偏振器(362),光电检测器(372)和菲涅尔透镜(376)增强了扭转扫描器(58)的光学性能。

    • A biocompatible, implantable microactuator (82) for a fully implantable hearing aid system includes a hollow body (84) that has an open first end (88) and, open first and second faces (94a and 94b). Flexible diaphragms (92, 96a and 96b), respectively covering the end (88) and faces (94a and 94b), hermetically seal the body (84). An incompressible liquid (98) fills the body (84). Transducers (102), provided by laminated, stress-biased unimorphs (32 or 62) that are mechanically coupled to the flexible diaphragms (96a and 96b), deflect the diaphragms (96a and 96b) in response to an electrical driving signal. Deflections of the diaphragms (96a and 96b) are coupled by the liquid (98) to the first flexible diaphragm (92). The unimorphs (32 or 62) include a layer of biocompatible metal (36 or 66-68) deposited on one side of a biocompatible piezoelectric ceramic plate (34 or 64) to stress-bias the plate (34 or 64). A thin, biocompatible electrode (44 or 72) coats the other side of the plate (34 or 64).

    • 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 impinges on the scanned surface (28) to exit the block (34) through a radiation outlet-face (42). After exiting the block (34), the beam (38) impinges 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.
    • 由微机械扫描器(54)的移动镜板(56)偏转的电磁辐射束(38)在块(34)的扫描表面(28)上产生二维(“2D”)光栅(132) 。 块(34)对于预先建立的波长的电磁辐射是透明的。 块体(34)的辐射入射面(36)允许射束(38)然后撞击在扫描表面(28)上,以通过辐射出射面(42)离开块体(34)。 在离开块(34)之后,光束(38)撞击在辐射检测器(142)上。 来自扫描表面(28)的光束(38)在指纹谷处的全内反射(“TIR”)和指纹脊上TIR的挫折使得辐射探测器(142)产生代表指纹的时变电信号 。 扫描表面(28)可以由弹性材料的贴片(302)形成,其可以仅在电磁辐射的预先建立的波长下被着色为透明。
