Patent EP-0422347-A2 (EP)
Inventor: SCHRECK JOHN F
IPC: G11C16/06
Filed: 1990-08-02
Abstract: The memory array circuit this invention provides connection of segmented bitlines (11) to bitline decoding circuitry (18) while, at the same time, providing connection of combined wordlines (14) to wordline decoding circuitry (19). The segmentation and decoding connections permit faster speed of operation with minimal or no area penalty. The area penalty is avoided by driving common wordlines (14) in each of the segments, effectively increasing the wordline pitch at the wordline decoder (19), while at the same time decreasing the number of wordline decodes required. The segmentation also permits location of the decoder circuit away from the signal and routing decode outputs.

Abstract: The invention relates to an X-ray generator for operating an X-ray tube with earthed tube parts and with a high-voltage transformer arrangement having in each case a secondary winding for generating the positive and negative high-voltage for the anode and cathode respectively of the X-ray tube. The unfavourable voltage distribution produced when such an X-ray tube is supplied by a high-impedance generator is overcome in a simple manner in that the two secondary windings each have a primary winding allocated to them and that an inductor can be connected in series with the primary winding for generating the anode voltage, by means of a switching device.

Abstract: This invention is a mobile, short range, high data rate, high availability atmospheric optical communication link which can be used to temporarily bridge a break in an optical fiber network. Briefly, the invention comprises two transceivers, one at each end of a break, to bridge a severed optical fiber via an atmospheric optical transmission path which can extend for a distance of roughly 5 miles. A special light source is not required. The light transmitted through the atmosphere is the low power light emitted from the end of an optical fiber and generated by an optical regenerator normally used to generate light only for transmission through an optical fiber. The light is first expanded and collimated for atmospheric transmission and then transmitted to a receiver. At the receiver, the diameter of the received beam is optically reduced by focusing it onto the end of an optical fiber for coupling the light into the fiber. The optics for the transmitter and receiver can be mounted on a platform that adjusts in real time to optimize the signal received. Optical alignment can be automatically maintained by computer controlled transmitter steering and receiver tracking. The transmitters and receivers require no communication other than the incoming beam to maintain optical alignment and does not require additional bits in the data stream for telemetry.

Abstract: A system for determining the magnitude of loads on rotating helicopter components from sensor signals remotely measured on the helicopter fuselage is characterized by a controller which samples the sensor signals according to phase. These measured signals are presented to a coefficient programming module where they are combined with correlation signals to correlate the measured signal components with the desired parameter, such as flatwise bending moments of a helicopter blade. The correlation signals are established in a calibration process that determines the independent values of the measured signals using a Jones orthoganization process. The signals output from the module are recombined to provide a time dependent signal corresponding to the desired parameter. The present system avoids decomposition and recomposition of the measured signals and therefor operates in real time.

Abstract: A method and circuitry for suppressing additive transient disturbances in an analog differential input signal, such disturbances being due, for example, to thermal asperity transients caused by an MR transducer (10) contacting a moving storage surface (11). The input data signal is algebraically summed by a summing circuit (14) with a corrective feedback signal for providing as output signal. The output signal is fed back to a circuit (16) including an envelope detector (15) and differentiator (17) and converted into another signal that is the derivative of an amplitude envelope corresponding to the output signal. Nonlinear signal-adaptive filter means (18) converts the other signal into the corrective feedback signal, which substantially replicates the additive transient disturbance and is subtracted from the data input signal to render the output signal substantially free of the transient disturbance. 
     The input, output and corrective signals are preferably differential signals.

Abstract: A method for measuring the coefficient of thermal expansion of calcined petroleum coke involves pressing a sample of the calcined coke with a binder pitch to form a pellet and baking the pellet at a temperature of at least 800°C. The coefficient of thermal expansion of the pellet is then measured. The method has the advantage of eliminating the graphitization and machining steps resulting in reduced manpower and turnaround time and requires less sample which allows CTE determination of laboratory scale cokers. Results show good correlation between this technique and traditional extrusion techniques.
