Abstract: To be able to compensate for the non-linear signal distortions occurring due to the "laser chirp" and the chromatic dispersion of the optical waveguide in analog optical transmission systems, an equaliser in the form of an LC section is known, the capacitance of which is formed by a capacitance diode. However, the known equaliser only functions when the capacitance has the suitable polarisation which cannot be predicted because of possible polarity reversal during the signal transmission. According to the invention, a further capacitance diode (Cb) is connected in parallel with the capacitance diode (Ca), with opposite polarisation, and is also biased in the reverse direction. By setting the bias voltage of the two capacitances, it can be achieved that optionally one of the two capacitance diodes handles the equalisation function and the other one is virtually ineffective. Further developments of this solution relate to keeping the frequency response constant during the adjustment of the equaliser, by means of a controllable capacitance connected in parallel with the capacitance diodes (Ca, Cb), and the equalisation of signals with large bandwidth by a cascaded LC circuit with LC sections according to the invention.   <IMAGE>

Abstract: A magnetic head (15) and line sensor (23) are mounted along the transport passage of a color negative film (10). The magnetic head reads trimming information recorded on a magnetic recording layer of the negative film, and sends the trimming information to an image processing unit (17). The line sensor scans an original frame of the negative film synchronously with the transportation of the film and reads the image data of the frame one line after another. In accordance with the trimming information, the image processing unit generates image data for a trimmed image as enlarged to use the color paper fully regarding its width, and sends the image data to a line printer unit (25). The line printer unit scans a light beam synchronously with the transportation of the color paper, to record the trimmed image one line after another on a color paper (26). According to a preferred embodiment of the present invention, at least two layers among cyan, magenta, and yellow coloring layers are made of photosensitive material sensitive to electromagnetic waves such as infrared light.

Abstract: An aircraft autoland flare control system which augments the autopilot's aircraft flare control commands in the event the aircraft exceeds defined flare envelopes, monitors aircraft longitudinal position, altitude, altitude rate, lateral position and lateral position rate during flare, and outputs commands to correct aircraft position thus minimizing touchdown dispersion in both the longitudinal and lateral axes. When the aircraft deviates from the flare envelopes, such as may be due to extreme atmospheric conditions such as wind gusts, a signal commanding pitch or roll correction is output to the pitch or roll control loop which subsequently acts to adjust aircraft position such that the aircraft's flarepath is returned to within the flare envelopes.

Abstract: Spurious memory readings which may be caused by noise induced by transitions in the output buffers of a fast parallel memory device are prevented by permitting output latches to change state in function of newly extracted data signals by means of an enabling pulse having a preestablished duration and which is generated only after a change of memory address signals has occurred and the new configuration of memory address signals has lasted for a time which is not shorter than the time of propagation of signals through the memory chain. The enabling pulse is generated by employing a detector of transitions occurring in the input circuitry of the memory, a dummy memory chain, a one-shot pulse generator and a resetting pulse generator. The anti-noise network may be exploited also for implementing an auto-stand-by condition at the end of each read cycle, which reduces power consumption and increases speed by implifying the sensing process.

Abstract: The object of the invention is to propose such a method and an apparatus for carrying it out, as a result of which a simplified control of a batch end, with the aim of as many full cross-wound bobbins as possible, is possible. This object is achieved, according to the invention, in that the predeterminable number of full cross-wound bobbins is divided by the number of winding stations of the machine producing cross-wound bobbins. In the event of a non-integral quotient, the latter is rounded up and down to integral values with an upper and a lower limit value, the sum of all the rounded-up and rounded-down values being equal to the predeterminable number. Such a value is predetermined to each winding station. The winding stations are put out of operation after the values have been reached. The machine producing cross-wound bobbins possesses storage locations for storing the acquired number of finished cross-wound bobbins per winding station. An input device for the input of desired values of the number of cross-wound bobbins of individual winding stations is coupled to a circuit for putting the winding stations out of operation when the desired value is reached. A cross-winding machine advantageously possesses a closed transport system for trolleys which carry the cops and tubes. <IMAGE>

Abstract: A method of matching the resonant frequency of an antenna resonant circuit (18,46) to the output frequency of a transmitter output stage (26), the method includes the step of providing a powering signal from the transmitter output stage (26) to the antenna resonant circuit (18,46). The method further includes the step of receiving at the antenna resonant circuit (18,46) the powering signal, the antenna resonant circuit (18,46) comprising a tuning circuit (48). The tuning circuit (48) is operable to variably modify the resonant frequency of the resonant circuit (18,46). At its output the antenna resonant circuit (18,46) provides a phase correlation signal having a known relationship to the frequency difference between the resonant frequency and the powering signal. A phase comparator (60) then receives the powering signal and the phase correlation signal and correspondingly adjusts the resonant frequency of the resonant circuit (18,46) based upon the known phase relationship. Other devices, systems and methods are also disclosed.
