Method of fabricating an image sensing array, such as one of the charge coupled device (CCD) type, with a set of transparent insulated conductors over the image receiving surface. A transparent conductor layer on an insulated substrate surface is covered with a thin layer of aluminum. The desired pattern of electrodes is then defined in the aluminum by, for example, a photolithographic masking and etching process. The aluminum remaining is then anodically oxidized to form aluminum oxide, a transparent insulator. The portions of the transparent conductor not protected by the aluminum oxide are then removed and what remains are transparent conductors covered on top by transparent insulation.
A relatively stable suspension of particles of a glycine containing material is formed by mixing the particles in a suspending medium of an alcohol saturated with glycine. The suspension is applied to a substrate and the alcohol is evaporated to form a film of the particles on the substrate.
A power transfer apparatus transfers electrical energy from a DC voltage source that may vary in potential, e. g. , a solar cell array, to a load such as a DC motor connected to drive an AC motor-generator. A power transfer device couples the solar cells to the DC motor for driving the DC motor at a power level consistent with the power available from the array of solar cells. The AC motor is continuously connected to an AC line to be driven by conventional AC power. The DC motor, when operating, reduces the load on the AC motor and thereby reduces the AC power drawn or in some cases, causes the generator driven by the DC motor to return power to the AC line.
A power transfer apparatus includes an impedance matching system coupled between a variable voltage source, e. g. , a solar cell array, and a load. A parameter of the load indicative of the power being delivered to the load is sensed and the control signal thereby derived is employed to adjust the impedance matching system. The adjustment is such as to maximize the value of the parameter.
Liquid crystal compositions compositions and liquid crystal thermometric articles, radiation sensors, and optical display devices comprised of a nematic liquid crystal solvent which is effectively transparent to radiation of near ultraviolet and visible wavelengths and a fluorescent solute whose visible fluorescent intensity varies with the phase or orientation of the liquid crystal solvent are disclosed.

For the past twenty years, Canadian singer-songwriter and performer Robert Larrabee has delighted audiences everywhere from the U.S. to London to Sydney—and, of course, throughout his native Canada. Robert has made a name for himself with an act audience members call “a great mix of music...
