    摘要: A gas measurement and analysis system having a gas chromatograph which converts a gas mixture from a source to a time varying continuous signal. This signal is sampled and converted to digital form by an analog to digital converter which provides a stream of amplitude dependent digital values at equally spaced time intervals. These sampled signals are applied to a rate of change estimator system which provides an accurate estimate of the time derivative of the sampled signal by means of recursive digital feedback. The output of the estimator system is applied to a processor.

    摘要: A multi-user, multi-task analog/hybrid system having a digital computer and a main digital memory. The programs are run with one of the analog and digital programs becoming time critical. A linkage system having ADC and DAM channels link the data flow between the analog computers and the digital computer. The linking system is controlled to substantially allocate all of the data flow to the time critical analog and digital programs and as available data flow is allocated to nontime critical programs. After allocation, there is automatic data transfer without digital computer intervention.

    摘要: Air turbulence simulation apparatus for providing pitch turbulence signals for simulating pitch turbulence and for providing roll turbulence signals for simulating roll turbulence, such apparatus including first means for providing first signals at a first predetermined frequency; second means for providing second signals at a second predetermined frequency; the second predetermined frequency being lower than the first predetermined frequency; summing means for receiving and summing the first and second signals and for providing third signals which are the sum of the first and second signals; coupling means for receiving the third signals and for providing the pitch turbulence signals and the roll turbulence signals; such simulation apparatus may also include differentiating means for receiving the third signals and for differentiating the third signals to provide the roll turbulence signals whereby the differentiated roll turbulence signals are of shorter duration than the pitch turbulence signals.
