Abstract: A method and apparatus for fixing images, holograms and domain gratings in crystals by application of an electric field on a crystal and simultaneous illumination of it with a light pattern. The fixing procedure is based on a screening effect. The modulation of the domains may be perpendicular to the c-axis. Another application of the method is in frequency mixing such as second harmonic generation and parametric processes, by overcoming the problem of phase matching using the domain gratings. Thus, it is possible to obtain controllable broadband mixing and tailored quasi-phase matching for several wavelengths or for prespecified wavelength tuning ranges and frequency widths.

Abstract: A method for producing a photodiode with a simplified planar device architecture based on a single layer of HgCdTe using a mature, established growth technology for the sensing material, combined with an implanted homojunction which is at least partially activated during MOCVD CdTe passivation. The device architecture is based on a planar structure, a p-on-n homojunction for sensing the infrared radiation, and a CdTe or CdZnTe/HgCdTe heterostructure for passivation. The MOCVD CdTe passivation can be applied ex-situ, irrespective of the growth technology of the sensing material, and the homojunction is at least partially activated while applying the CdTe passivation. Thus, a major simplification in device architecture is achieved, based on a single layer in contrast to known, double layer heterostructures.

In its operative position, the sunshade covers all the automobile's windows providing protection against the sun regardless of the time of day that the sunshade is deployed or the orientation of the parked vehicle. The sunshade does not cover the automobile's registration plates or rear reflectors.

Abstract: A treatment and stimulation device provided as a compact, portable unit having an applicator capable of horizontal and vertical movements for manipulation of the skin and underlying tissue under electronic circuit control. In a preferred embodiment, the applicator is provided with reversible rotation directed against the skin to provide horizontal movement having uneven angles of deflection, and vertical up/down movement is supplied by a solenoid. By virtue of the electronic control, these movements are continuously variable, and can be integrated and finely controlled, to produce any desired physical stimulation effect on the skin and tissue, for medical or cosmetic purposes. The different kinds of receptors in the skin and tissue can be selectively activated, since they are frequency dependent and direction-force dependent.

Abstract: A vertical trencher having a cutter body with cutting teeth arranged in a spiral configuration on its circumference with an increasing rise angle, for excavating various size trenches, which is operable at high speed and efficiency, and suitable for use on hard and rocky ground. The cutter body is formed with a spiral-shaped concave channel, with grinding teeth attached to its outer edge. The grinding teeth cut soil and rock loose, so that pieces are scooped into the concave channel. The rise angle of the concave channel to the horizontal increases along the length of the cutter body. Thus, loose pieces of soil are transported upwardly along the concave channel at an increasing axial speed. The cutter body is connected at its upper end to a hydraulic engine mounted on the housing, which provides rotational power.

Abstract: A microprocessor-based apparatus provided as a dedicated control unit, which enables a standard software protocol to provide a digital presentation of security criteria associated with stable analog process data relating to recurrent processes in businesses and utilities. The general method introduced here provides security criteria data in two functional control loops: First, the I-criterion provides continuous monitoring of the input analog signal and interruptions thereof, which are presented in time units. Second, the Q-criterion provides the input analog signal conversion in digital form, and identifies the signal quality by determining whether it falls within or deviates from a standard tolerance range. In addition, a stochastic signal decomposition is performed to provide four 6-hour disjoint data files within a behavioristic control loop/each calendar day.

Abstract: Logic elements for use in carry/borrow and comparator systems, which operate in accordance with the IMPLY logical relationship. Utilization of the IMPLY logical relationship overcomes the inherent complication of inversion so that it becomes an effective benefit, making possible uniform carry system layouts with uniform logic elements using a newly defined gate pair combination in general. The gate pair logic elements provide a novel carry-propagate signal (P) which includes a redundant carry-generate signal (G), thereby defining a novel carry-integrate signal (I) . The novel carry-integrate, signal (I) together with the carry-generate signal (G) define a signal pair utilized in succeeding carry levels which are organized in a simplified fashion. For-2-bit position (i+1, i) positive sense logic, the carry-integrate signal can be represented by I(i+1, i)=G(i+1)+P(i+1). P(i)) . Wherever the IMPLY relationship is involved in logic functions, the design of CMOS gates is affected and can be modified.
