Inventor: POTTER RONALD W
IPC: G01M99/00
Filed: 1985-08-08
Abstract: The apparatus determines the poles and zeroes of a device by applying a stimulus signal to the device, detecting the stimulus and response signals and computing the auto-power and cross-power spectra therefrom. An estimated transfer function comprising a rational fraction of two Chebyshev polynomials is least squares fit to a measured transfer function obtained from the auto-power and cross-power spectra and the poles and zeroes are obtained as the roots thereof. A weigthing function may be used to emphasize certain desired regions of the frequencies of interest in the determination of the least squares fit. Inaccuracies due to noise are minimized by subtracting out the noise bias from the squared cross-power spectrum obtained during the least squares fit and by orthogonalizing a data matrix used in the determination of the coefficients of the estimated transfer function. Inaccuracies due to noise and computational error are further minimized by the use of the Chebyshev polyno- , mials. The orders of the poles and zeroes are modified until an optimum fit is reached.

Abstract: The apparatus for measuring an AC electrical parameter of a device (3) with DC bias applied to the device (3) during measurement includes a control means (13, 18) coupled to sense the bias voltage across the device (3) and to regulate the bias voltage to a desired value. The apparatus includes a high bandwidth, high frequency current sensing amplifier (4, 5) for pulling a terminal (A2) of the device (3) to ground. Redesign of the current sensing amplifier for improved DC performance is avoided by having the control means (13,18) change the bias voltage on the other terminal (A1) of the device (3) if the potential at the first terminal (A2) departs from virtual ground because of limited DC performance of the current sensing amplifier (4, 5).

Abstract: An encoding method for an anologue waveform, such as a speech waveform comprises deriving a digital data stream from the waveform, dividing the digital data stream into a number of successive time frames of equal period and storing the data. A stream of time encoded symbols is also derived from the analogue waveform, divided into successive time frames corresponding to those of the digital data stream. The distribution of the time encoded symbols for successive time frames is determined and a digital data stream for subsequent decoding is reconstructed from the digital data stored in combination with derived digital data which is dependent upon the results of the comparison of the encoded symbols.

Abstract: During operation of an apparatus to machine a workpiece, an unfinished workpiece is gripped by a workpiece loader and unloader assembly at a conveyor station. The loader and unloader assembly moves the workpiece along the axis of a spindle assembly through an opening in a shield which minimizes the accumulation of material cut from a workpiece on the loader and unloader assembly and on a conveyor assembly. The loader and unloader assembly moves a finished workpiece from the spindle assembly, rotates a support arm through a distance which is less than 90° to the condition of an unfinished workpiece in alignment with the spindle assembly and inserts the unfinished workpiece into the spindle assembly. The workpiece loader and unloader assembly then comes back through the opening in the shield and transfers the finished workpiece to an outfeed section of the conveyor assembly.
