The OSB circuit has a voltage controlled capacitance connected in circuit with each output terminal to control the effective capacitance between the output terminals and ground. The bias voltage for the variable capacitances is calibrated by a method in which the voltage for one of the variable capacitors is held constant while the voltage for the other capacitor is varied in voltage levels. A test signal frequency sweep is applied to the test unit output terminals. First and second voltage values are obtained and a final bias voltage value is calculated from using these two values.

Abstract: In a level shift circuit, when a signal at a low voltage signal level applied at the signal input terminal changes from a LOW to a HIGH level, an inverter is boosted in input voltage level by a voltage booster on the basis of the voltage of a capacitor element charged through a diode element and on the basis of the input signal variation such that the inverter assumes an input voltage level above the aforesaid low voltage signal level. This enables the inverter to perform an inversion operation without fail and the signal output terminal provides a HIGH level signal at a high voltage. In addition, when the input signal changes from HIGH to LOW, an input of the inverter is pulled down directly by an N-channel transistor coupled to a ground power source to LOW. Accordingly, also in this case, the inverter performs an inversion operation without fail.

The sensing circuit utilizes the inherent delay during sensing, i.e., the period between when an enable signal is enabled and when data is valid, by pulling a node of a transition logic circuit to a midpoint voltage.

Abstract: This invention relates to an improved procedure and apparatus for making colored polyurethane foam products, such as carpet underlay and the like, as well as the improved colored product itself. Such a procedure entails the utilization of at least one valve assembly within a color dosing manifold such that the valve itself is simultaneously in contact with both the outside surface and the inside surface of the manifold. Such a disposition for a valve assembly permits color to be introduced directly into a binder (i.e., polyol and isocyanate) or polyol stream in order to substantially eliminate any color remaining in contact solely with the inside walls of the manifold. This in turn permits thorough mixing of the binder and colorant and substantially reduces the response time from opening the valve to producing colored polyurethane materials (such as polyurethane foam), thereby effectively eliminating the production of waste polyurethane product.

In the present invention, the access time of various optical discs is identical regardless the size of the single track width formed on the optical discs.

Abstract: A peak power regulator is disclosed that functions within a Code Division Multiple Access (CDMA) transmitter to reduce peak power spikes within baseband signals, controlling the out-of-band emissions, and maintaining the in-band signal quality within an acceptable degradation. In-phase and quadrature baseband signals are input to an envelope magnitude predictor within the peak power regulator. The envelope magnitude predictor outputs an estimate for the magnitude of the envelope that will be generated when the inputted baseband signals are modulated. This estimate is input to a multiplier that generates a ratio by dividing the estimate by a maximum acceptable envelope magnitude. The ratio is subsequently input to a mapping table that outputs a scaling factor sufficient for reducing peak power spikes. The scaling factor is subsequently subtracted from a value of one and multiplied by first delayed versions of the in-phase and quadrature baseband input signals.
