Abstract: An improved hologram display panel for a vehicle. Sensors can monitor the operating characteristics of the vehicle and virtual images of indicators can be realized by the illumination of holographic images that are contained in substantially transparent hologram members laminated to the surface of the windshield. The holographic images are virtual image displays that can appear offset from the windshield to accommodate the vision of the driver.

Abstract: Close tolerance waveguide assemblies for use in antenna arrays. In particular, the waveguide assemblies are configured along the zero electrical current lines in the antenna array. Such waveguides are particularly useful in antenna arrays for radar systems operating at the microwave and millimeter-wave frequencies. In the invention, antenna array assemblies, such as rectangular or ridged waveguide assemblies, are configured by combining plates which are formed into a plurality of equal length members protruding from and perpendicularly disposed to a structural member, wherein each such protruding member has two formed or unformed ends.

Abstract: Liquid crystals are induced to assume a uniform tilted alignment in the absence of an applied field by treating the surface of a substrate to provide a desired tilted surface microstructure and free hydroxyl groups. A long chain alcohol having the formula ROH, where R is a carbon chain having at least about 6 carbon atoms therein, is chemically reacted with the tilted surface microstructure and the alkoxy groups derived therefrom are chemically bonded to the microstructure. Subsequently introduced liquid crystals assume a tilted-perpendicular alignment at a tilt angle of about 0.5° to about 6°. The liquid crystals exhibit a significantly greater photostability than has previously been achieved. The microstructure is preferably obtained by depositing sequential layers of SiOx at medium and shallow grazing angles, where x is from 1 to 2, with the substrate rotated 90° between depositions.

Abstract: A process for depositing diamond (12) onto a substrate (14), which is of particular utility in fabricating very thin layers of diamond. Diamond (12) is deposited by chemical vapor deposition of a hydrocarbon vapor wherein the carbon atoms are saturated and the ratio of hydrogen atoms linked to carbon atoms is less than 2. That is, the carbon atoms of the hydrocarbon are bonded by single bonds at an angle near 109.5 degrees, the same angle required for the carbon atoms in the deposited diamond. The limited number of hydrogen atoms ensures a compact structure for the hydrocarbon, and reduces the system burden of removing excess hydrogen upon deposition. The polycyclic alkanes exhibit the required structures. Preferred hydrocarbons include adamantane (Fig. 2), congressane (Fig. 3), cubane (Fig. 4), and basketane (Fig. 5).

Abstract: Impedance matching using lossless elements for optoelectronic components. In one embodiment, a fiber optic link has a laser diode (10) optically coupled by an optical fiber (14) to a photodiode (12). The laser diode is matched to the RF source (16) by a reactive matching circuit (M1). The photodiode is matched to the load (18) by a second reactive matching circuit (M2). Both matching circuits are comprised of lossless elements, as opposed to resistive elements, for achieving a match with minimal RF-to-RF insertion loss.

Abstract: A satellite communications system employs separate subsystems for providing broadcast and point-to-point two-way communications using the same assigned frequency band. The broadcast and point-to-point subsystems employ an integrated satellite antenna system which uses a common reflector (12). The point-to-point subsystem achieves increased communication capacity through the reuse of the assigned frequency band over multiple, contiguous zones (32, 34, 36, 38) covering the area of the earth to be serviced. Small aperture terminals in the zones are serviced by a plurality of high gain downlink fan beams (29) steered in the east-west direction by frequency address. A special beam-forming network (98) provides in conjunction with an array antenna (20) the multiple zone frequency address function. The satellite (10) employs a filter interconnection matrix (90) for connecting earth terminals in different zones in a manner which permits multiple reuse of the entire band of assigned frequencies. A single pool of solid state transmitters allows rain disadvantaged users to be assigned higher than normal power at minimum cost. The intermodulation products of the transmitters are geographically dispersed.

Abstract: Rapid frequency synthesizer apparatus, particularly for use in high speed frequency hopping systems, includes a voltage controlled oscillator (VCO) and a memory (104) in which are stored digital control voltage commands corresponding to the various frequencies to be synthesized by the VCO (102). A controller (110), responsive to channel selection commands (120), addresses the memory (104) and causes the corresponding digital control voltage command to be generated. A digital-to-analog converter (106) receives the digital control voltage command and converts it to an analog control voltage signal (130) which is fed to the VCO (102). The resulting VCO output signal (132), at frequency, fout, is compared in a frequency counter (108) with a reference frequency, fR. The controller (110) controls operation of the frequency counter (108) so that a difference between the actual synthesized frequency and the programmed frequency is determined. Responsive to this difference, the controller (110) causes the addressed control voltage command to be modified in a manner designed to reduce the difference the next time the same programmed frequency is selected. A corresponding method for providing rapid frequency synthesis is described.
