Abstract: The invention is directed to a directional coupler (61) for coupling together a radar frequency transmitter (58) to a combined transmitting and receiving antenna (48), a power absorber (62) and a receiver (64). A tunable stub (69) is employed to reflect a selected amount of transmitted energy (67) to the local oscillator (LO) of the receiver for mixing with the incoming received signal. The coupler can be constructed from any known type RF transmission line suitable for passing or coupling signals of radar frequencies. A significant amount of the transmitter power is absorbed in a power absorbing RF load allowing only a small amount to be transmitted from the antenna (65) and a still smaller amount (67) fed back as LO to the receiver (64). The invention works equally as well on a dish type antenna and a phased array antenna.

Abstract: In the preferred embodiment of the invention, a first-in, first-out (FIFO) memory includes flag generation circuitry which utilizes a write clock counter and a read clock counter to provide the number of write clock pulses received since the previous write reset signal and the number of read clock pulses received by the FIFO since the previous read reset signal. A subtractor circuit subtracts the number of read clock pulses from the number of write clock pulses, and this difference is compared in a comparator circuit to determine if the difference is greater than a preset value. This determination provides the information as to the relative fullness of the FIFO. Specific flag values are user-programmed and are stored electronically as binary numbers in registers. The connection between individual subtractor circuits and individual comparator circuits for making the comparison is performed by a program select decoder which utilizes the difference output of the subtractor circuit and the flag program value.

Abstract: These methods and arrangements provide the possibility for fast averaging of a multiplicity of camera images in video real time. A camera (9, 18) picks up an interference pattern or the image of a projected stripe pattern. The differences of the phase values of adjacent data points are then modulo-2 pi  calculated in differentiating circuits (26, 30) and these differences of several camera images are added together in adders (27, 31). It is only after these differences of the phase values of the desired number of camera images have been added together that a single elimination of discontinuities is carried out. …<IMAGE>…

Abstract: A full color upconversion laser (20) pumped by a single wavelength infrared laser source (25) is disclosed. The pump energy excites a rare earth doped crystal (35) and can simultaneously lead to laser emission at several wavelengths. The laser (20) includes a crystal (35) of YLiF₄:Er 5% fabricated in a monolithic structure which incorporates the laser mirrors (40, 45) as dielectric coatings on spherical surfaces (42, 47) of the crystal rod (35). The mirrors (40, 45) are optically reflecting at one or more of the desired output wavelengths. The laser rod (35) is mounted in a helium cryostat (50) that permits the operating temperature to be varied between 15 and 120°K. The pump energy is supplied through one of the mirrors (40) specifically designed to be simultaneously highly reflecting at the laser wavelength and highly transmitting at the pump wavelength. To achieve optimum efficiency, a lens (30) is used in the pump path to focus the pump beam in such a manner as to provide a match of the laser mode size and pumped region of the crystal (35).

Abstract: A method and an apparatus are described for making transport crates, in particular crates for bottles, by the injection-moulding process, which permit the production of inner cavities in large-volume cross-sectional areas of the crate, for example the grip and corner-member areas. For this purpose, apart from the normal injection points, usually arranged in the bottom of the crate, additional injection points are provided in the region of the large-volume cross-sectional areas of the crate. At these additional injection points, a compressed gas, for example nitrogen, is introduced at high pressure into the respective stream of plastic and results in the cavities in the large-volume areas. The compressed gas is subsequently allowed to escape.

Abstract: In the generation of screened halftones of photographic images for low resolution marking devices, conventional screen techniques are too coarse, and adaptive dither techniques are too fine. The present invention preserves the advantages of the adaptive dither techniques, while creating screen patterns with an adjustable degree of coarseness. The invention applies a hysteresis constant and recursion techniques previously limited to adaptive screening with fixed dot patterns to vary the size of dots in the screened image, thereby allowing adjustment of the image coarseness by adjusting the hysteresis constant.

Abstract: According to the present invention, during programming of a programmable logic device, programming in formation corresponding to an input signal is loaded into a shift register. This input information is compared with programming information corresponding to a second, complementary input signal to determine if the two signals are used by the programmable logic device. If the two inputs are not used, a bit is stored in a memory cell indicating such nonuse. An input buffer is disabled when the bit in the memory cell indicates the complementary signals corresponding to that input buffer are not used.
