摘要： A method and apparatus for detecting and classifying particles on a surface in which condensation is used to enlarge particles. An apparatus of the present invention includes a heatable wick disposed over a test surface and in fluid communication with a source of volatile liquid. A zone of vapor supersaturation is thus created in which condensation on particles on the surface can occur. A light beam directed onto the surface scans the surface. Droplets are detected by means of light scattered from the droplets. In an alternate embodiment a stream of carrier gas may be provided around the wick or bubbled through a jar of volatile liquid to direct a vapor toward the test surface. In another embodiment, multiple wicks communicate with different sources of volatile liquids. In a method of the invention, mulitple scans are made with either different levels of vapor supersaturation or different vapor compositions. Comparing particles in each scan allows one to classify particles into different size ranges or chemical type.

摘要： A method for fabricating a microtip, cantilevered from a base and having a controllably high aspect ratio, for use in microprobe microscopy to probe variations in materials at the atomic level. A two-layer semiconductor material structure is provided, one layer being n type and the other layer being p type. A thin pencil of ions of n type is implanted through the n type layer into the p type layer, through a small aperture in a mask layer that overlies the n type layer. The p type material is then etched away, leaving the n type ion profile and the n type layer as a cantilevered microtip. The n type semiconductor layer may be replaced by a layer of any material that resists etching by the selected etchant.

摘要： An improved fully implantable hearing aid (10) in a first aspect includes at least two microphones (28) to provide improved noise cancellation, and, with an array (132) of microphones (28), improved directivity. In a second aspect, the hearing aid (10) includes an improved microactuator (32') in which deflections of a pair of piezoelectric plates (68) are coupled by liquid (52') to a flexible diaphragm (44') for stimulating fluid (20a) within an inner ear (17) of a subject (12). In a third aspect, the improved hearing aid (10) includes a directional booster (200) that the subject (12), having an implanted hearing aid (10), may wear on their head (122) for increasing directivity of perceived sound. A fourth aspect of the present invention is an improved implantable microactuator (32", 32'") that generates a mechanical displacement of a diaphragm (82) or a face (96) in response to an applied electrical signal. A liquid coupling between the piezoelectric transducer (54", 54'") and the diaphragm (82) or face (96) provides a mechanical impedance match for the transducer (54", 54'").

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 hearing aid includes an implantable microphone, signal-processing amplifier, battery, and microactuator. An electrical signal from the microphone is amplified and processed by the amplifier before being applied to the microactuator. The microactuator is adapted for implantation in a subject at a location from which it may mechanically create vibrations in the perilymph fluid within a subject's inner ear. A transducer of the microactuator is preferably a thin circular disk, 2 to 8 mils thick, of stress-biased PLZT. Disks of this stress-biased PLZT material can be mounted as drumheads in various different ways, preferably in conjunction with a flexible diaphragm, to small threaded metal tubes, e.g. 1.4 mm in diameter and 2.0 mm long. These tubes may be implanted into a fenestration formed through the promontory adjacent to the oval window of a subject's inner ear. Securing the disk to a tube having a larger diameter than that implanted into the fenestration and filling the tube with fluid provides hydraulic amplification of the transducer's displacement. The implantable microphone is preferably fabricated from a thin sheet of PVDF that is overcoated with inert metal electrodes.

摘要： A method of making an electron permeable window is provided which entails depositing a thin film of an inert, high strength material or compound having a low atomic number onto a substrate by chemical vapor deposition (CVD). Following that deposition, a window pattern and window support perimeter are photolithographically defined and the substrate is etched to leave the desired window structure. For a particular class of materials including SiC, BN, B.sub.4 C, Si.sub.3 N.sub.4, and Al.sub.4 C.sub.3, films are provided which are exceedingly tough and pinhole free, and which exhibit nearly zero internal stress. Furthermore, due to their extreme strength, these materials allow fabrication of extremely thin windows. In addition, because of their low atomic number and density, they have excellent electron penetration characteristics at low beam voltages (15 to 30 kV), so that most conventional CRT deflection schemes can be used to direct the beam. Also, such films are remarkably resilient and chemically inert even when very thin and can easily withstand large pressure differences.
