Abstract: The invention relates to a circuit arrangement for correcting linear and non-linear transfer characteristics of electroacoustic transducers within the entire range of modulation (small- and large-signal behaviour), consisting of an electrical equaliser network which is coupled to the connecting terminals of the transducer and an aid, which is connected either temporarily or continuously, for matching the equaliser network to the transducer. The equaliser network (1) consists of a chain circuit of transmission elements, at least one transmission element (two-terminal network Z) exhibiting a non-linear transfer characteristic between its input and output port. The non-linear equaliser network contains linear transmission systems, multiplicative and additive logic elements and non-linear volatile two-terminal networks which are interconnected in accordance with the balanced active structure of the transducer. The parameters of the non-linear volatile two-terminal networks are variable by means of control signals (39, 40, 41). The matching aid activated only for matching purposes contains a main controller (89), a generating part (75) for generating an excitation signal and an analysis part (76) for converting the measurement signal, picked up via a sensor (3), into control signals (39, 40, 41) for automatically setting the parameters of the equaliser network. The equaliser network matched to the transducer (2) by means of this aid changes the linear transfer characteristics and reduces the non-linear distortions of the overall system. The invention is characterised most clearly by Figure 22. <IMAGE>

Abstract: The first process for producing an optical fiber coupler includes a first step (1) wherein at least one of the optical fibers to be used is stripped of the coating, a second step (2) in which the bare portion of that optical fiber is heated for a predetermined time to diffuse the dopants, a third step (3) wherein the other optical fibers which have not been heat-treated are stripped of their coating, a fourth step (4) in which the bare portions of all the optical fibers are heated as they are brought into intimate contact, thereby forming a unitary portion, and a fifth step (5) wherein the unitary portion is drawn via heating to form the coupling portion of an optical fiber coupler. The second process for producing an optical fiber coupler includes stripping the coating from at least one optical fiber, fixing the fiber so as to impart an axial stress thereto and then heating the bare portion of the stripped optical fiber thereby thinning the diameter of the heated portion, and then proceeding in the same manner as described with respect to the third through fifth steps of the first embodiment of the present invention. The processes according to the present invention enable a wide-band optical fiber coupler to be easily produced without using optical fibers of different structures but using optical fibers of identical structures.

Abstract: In a bit mapped display environment which has n hardware color look-up tables (CLUTs) where n = 1 or more, which also has a limited number of Display Attribute Identification Values, and which may operate under various window systems, such as the X Window System protocol, an apparatus and a method for installing and uninstalling hardware colormaps under the constraint of a finite number of Display Attribute Identification Values, whereby the most recently installed (MRI) policy of the X Window System is followed. The invention provides a scheme which gracefully degenerates to some "color flashing" when Display Attribute Identification Values are exhausted; which allows Display Attribute Identification Values to be uncoupled from colormap management and used for more graphics intensive functions when needed; and which dynamically regenerates when display attributes again become available. The invention also minimizes the rendering of the Display Attribute Planes when a new colormap is installed in a system containing multiple hardware color look-up tables.

Abstract: An optical exposure system for a color video printer, comprising a microprocessor for controlling optical exposure for R, G and B video signals, a memory device for storing the R, G and B video signals by the frame, a drive control device for inputting R, G and B video data from the memory device and outputting signal voltages and gate voltages of fixed levels as drive control signals for optical exposure of a photosensitive medium, and a LCD panel for performing the optical exposure of the photosensitive medium in response to the drive control signals from the drive control device. The gradation number of exposure amount is determined by fixing levels of the signal voltages to fix transmitivities of R, G and B liquid crystal elements and determining the number of exposure times by R, G and B pixels to be proportioned respectively to the R, G and B data values. Therefore, gradations of colors to be printed by the color video printer can be increased in number so that sensitivity differences among R, G and B colors can be compensated for and visually-natural colors can be reemerged.

Abstract: Apparatus and method are disclosed for determining the resistivity of formations surrounding an earth borehole. An electrically conductive metal body (202), such an a drill collar on a drill string, is movable through the borehole. A transmitting toroidal coil antenna (205) is disposed on the body (202) and is energized to induce a current which travels in a path that includes the body (202) and the formations. An electrode (226,227,229,235) is disposed on the body, and a first signal which depends on the electrical effect of the current on the electrode is measured to obtain an indication of the resistivity of the formations. In a form of the invention, a second transmitting toroidal coil antenna (T2) establishes a second current in the body (202) that travels in a path that includes the body (202) and the formations, and a second signal is measured at the electrode (R). A current monitor measures the axial current passing a monitor position on the body, to obtain a monitor current value. A compensated indication of formation resistivity can then be obtained as a function of the first signal, the second signal, and the monitor current value. A local communication system facilitates the ultimate communication of information to the earth's surface.

Abstract: The requirement of a separate payload clock in an ATM system is eliminated by increasing the number of bytes in an ATM cell and controllably generating and inserting idle cells so that a clock rate equal to that of the incoming SDH, SONET or the like clock rate may be used as a read clock. In one embodiment, the number of cells in a predetermined interval, for example 125 µ sec., is adjusted to be a predetermined integer number by inserting idle cells. This, in turn, allows the use of a "standard" available clock to delineate cell boundaries.

Abstract: A two-dimensional active antenna array, in particular, is proposed having an optical beam-forming network for on-board radar and Synthetic Aperture Radar (SAR) using x-band. Special shapes of the antenna aperture, use and frequency band are possible. A transmitted signal or local oscillator signal in the microwave frequency band and an alternatively additional digital signal modulate a central electrooptic transducer, using the time-division multiplex method. The optical heterodyne signal of this electrooptical transducer is injected into an optical beam-forming network, is amplified via at least one optical amplifier and is transferred to the individual T/R modules in a corresponding manner via optical dividers. After conversion of the optical signals by means of an optoelectrical transducer, and after phase-weighting and amplitude-weighting of the microwave signals, amplification is carried out followed by emission of the electromagnetic signal by means of aerial elements. Based on this arrangement, a further active antenna array is described which uses the beam-forming network bidirectionally. <IMAGE>
