    摘要: An electrode for a lead-acid voltaic cell comprises a high surface area, high porosity 3-dimensional lattice structure wherein the core elements forming the lattice are substantially contiguous. The core elements are coated with one or more corrosion resistant and conductive materials, and solid active materials are coated on the core elements and retained within the matrix. The lattice structure acts as the current collector.

    摘要: A fibre Bragg grating is used to stabilize the intensity and frequency fluctuations of two diode lasers simultaneously. The polarized optical output from the diode lasers is collimated and directed through a beam combiner device which combines the separate beams into a single beam, thus summing the optical power. The combined beam is directed into an optical fibre containing a fibre Bragg grating which reflects a fraction of the light back into each diode laser to cause low-coherence, stable operation of each laser.

    摘要: A totally implantable microphone for use with an implanted hearing aid comprises a cylindrical bio-inert housing having a bio-inert metallic membrane at the acoustic sensing end and a bio-inert plate containing electrical lead-throughs at the other end. The cylindrical housing is implanted in the posterior wall of the external auditory canal, with the thin auditory canal skin overlaying the microphone membrane surface. Surface features on the housing ossiointegrate it to the auditory canal bone, and a flange on the housing posterior end prevents post-operative migration into the auditory canal. A support plate beneath the membrane limits inward flexing and increases the signal-to-noise ratio. A protruding rim around the membrane perimeter acts to protect the membrane from rupturing during outward flexure. Lithographically formed wires laminated in a thin inert polymer and connected to the lead-throughs enable the overall length of the encapsulated microphone to be very short.

    摘要: Apparatus for stabilizing multiple laser sources having distinguishable optical characteristics, e.g., in polarization field or operational wavelength, comprises a plurality of semiconductor laser sources having respective lasing cavities capable of lasing within a narrow bandwidth of wavelengths and providing spectral outputs at their respective laser exit facets having different optical characteristics from one another. The spectral output beams of the sources may be coupled to respective optical fibers and the beams combined via a beam combiner, e.g., a polarizing beam combiner or a WDM combiner. The beam combiner combines the beam outputs forming a single beam which is launched into an output optical fiber. At least one feedback fiber grating is provided in at least one of the optical fibers with the number thereof depending upon distinguishable optical characteristics of the multiple laser sources. In the case of distinguishable optical characteristics in the form of polarization field, one grating is required and in the case of distinguishable optical characteristics in the form of operational wavelength, multiple gratings are necessary equal to the number of laser sources. The fiber grating or gratings have a reflectivity band for reflecting back a small portion of selected wavelengths of the single beam which are within the gain bandwidth of the laser sources while the remaining portion of the single beam transmitted through the grating or gratings to a final output. The grating or gratings have a reflectivity level approximately equal to or less than the reflectivity level of the laser source exit facets. The grating or gratings are positioned in the optical fiber or fibers to have an optical separation from the laser sources to cause the laser sources to operate in multiple longitudinal modes broadening the spectral output of the laser sources by several orders of magnitude.
