  • Patent number: 5418878
    Abstract: A cable system having a coaxial cable and a plurality of twisted wire pairs and optical fibers has the capacity to carry a broad range of telephonic, video and demodulated data signal information in addition to optical signals. The cable is suitable for long distance telephonic, video and optical signals as well as transmitting signals directly into the home or office of an end user. In addition, the cable is suitable for use in local all-optical networks and for long distance and broad network all-optical cable systems of the future.

  • Patent number: 4490329
    Abstract: A method for the implosive consolidation into a solid body of a mass of free particles, which mass consists, selectively, entirely of amorphous particles, or a mixture of amorphous and nonamorphous particles. During the consolidation act, pressure and temperature are controlled in a manner which assures that the consolidated amorphous particles in the solid body exhibit substantially the same amorphous characteristics as those displayed by the unconsolidated, free amorphous particles.

  • Patent number: 4427457
    Abstract: A depthwise-oriented capacitor comprises a cluster of separate, parallel, narrow elongated oppositely-doped conductive regions extending depthwise into a semiconductor substrate, for example, in an integrated circuit. The conductive regions can be parallel plates, but are preferably column shaped. The conductive regions are formed by ion implanting or diffusing a dopant into the substrate in a direction aligned with a crystallographic channel thereof to facilitate maximum ion penetration. P-type regions form one pole of the capacitor and N-type regions interspersed among the p-type regions form the opposite pole. Doping concentrations within the regions are sufficient to establish metal-like electric field boundary conditions. The bulk of the substrate containing the conductive regions is either near-intrinsic or semi-insulative so that the semiconductor material between the conductive regions is substantially nonconductive.

  • Patent number: 4139303
    Abstract: Recognizing and counting geometrically distant objects, such as objects of a particular morphological type (e.g., reticulated red blood cells), located in a field of objects of varying types is disclosed. Coherent light is directed toward a monolayer of objects of various types. The light scattered by the objects is collected by a collecting lens and forms a composite Fourier spectrum at the focal plane of the lens. The Fourier spectrum is selectively analyzed on the basis that each object creates a unique portion of the composite Fourier spectrum, and that a family of objects that are geometrically similar have additive spectrums, when their population is large, randomly located, and nonoverlapping. The analysis is performed by making intensity measurements at radial points in the Fourier plane, weighting the measurements, and summing the result. The radial points and weighting factors are determined using regression techniques.

  • Patent number: 4067645
    Abstract: A method of forming a minimum mean-square error linear filter photographically is disclosed.The optimum filter may be obtained photographically. In one form, a first photographic negative of a monolayer of cells having a high percentage of cells of the given type is made at the focal plane of a transforming lens mounted so as to collect the light scattered by the monolayer; and, developed for a gamma of unity. Thereafter, a second photographic negative is made at the same focal plane of a monolayer of cells containing a normal percentage of cells of the given type using the first negative as a filter. The second negative is developed for a gamma of two. The resulting photographic plate is a realization of the desired optimum (minimum mean-square error linear) filter.

  • Patent number: 3947123
    Abstract: Cells of a given type spread among an ensemble of cells of various types are identified and, if desired, counted. Coherent light is directed toward a monolayer of cells of various types. The light scattered by the monolayer of cells is collected by a lens and the collected light is filtered by an optimum filter located in the focal plane of the lens. The optimum filter is a minimum mean-square error linear filter which suppresses light scattered by cells other than the given type of cell whereby the light scattered by the given type is enhanced. The intensity of the light passed by the optimum filter is related to the number of cells of the given type contained in the monolayer of cells. If desired, a second lens may be used to collect the filtered light and focus it toward an integrating and squaring detector.The optimum filter may be obtained photographically.
