    Abstract: A fenestration piercing the otic capsule bone of the cochlea receives a therapeutic appliance, such as a microactuator, plug, micropump for drug or therapeutic agent delivery, electrode, and the like. Several different ways of achieving a ‘water tight’ seal between the otic capsule bone and the therapeutic appliance are provided. The therapeutic appliance may be implanted with or without a sheath or sleeve lining the wall of the fenestration formed using specialized surgical burrs. The burrs permit safely fenestrating the otic capsule bone adjacent to the scala tympani of the cochlea without damaging the basilar membrane or organ of corti. This approach may also be adopted for safely fenestrating other areas of the inner ear such as the scala vestibuli, bony labyrinth of semicircular canals, or walls of the vestibule, or the oval or round windows thereof.

    Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) arranged in a V-shape which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs deflectors (172) coupling a beam of light (108) between optical fibers (106).

    Abstract: 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).

    Abstract: 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).

    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 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.

    Abstract: A microfluidic delivery system (20) and microfluidic system (100) control flows of a liquid or a gas through elongated capillaries (62, 126) that are enclosed along at least one surface by a layer (42, 114) of a malleable material. An electrically-powered actuator included in the systems (20, 100) extends toward or retracts a blade from the layer (42, 114) of a malleable material to either occlude or open capillaries. Reservoirs (46, 124) included in a pouch (22, 108) together with the capillaries (62, 126) supply fluids whose flow is controlled by movement of the blades. The microfluidic system (100) permits dispensing at will, under microprocessor control at predetermined flow rates, liquids, samples, chemicals, reagents and body fluids, and mixing them together and/or reacting for diagnostic medical or analytical tests, DNA sequencing etc. The microfluidic delivery system (20) and microfluidic system (100) may be used for clinical testing, environmental or forensic testing, analytical chemistry, fine chemistry, biological sciences, combinatorial synthesis, etc.
