Abstract: The present disclosure is directed to both a method and apparatus for providing data dynamically during the drilling of a borehole. This invention can be used with drilling apparatus which is commonly used to drill oil or gas wells, including wells which are vertically drilled or highly deviated wells. The invention provides measures of weight on the drill bit and other forces acting on a drill stem in the vicinity of the drill bit. The present invention is incorporated within the drill stem, which is powered from the surface by a typical rotary drilling rig. The associated drilling apparatus, however, further includes and incorporates a mud motor cooperating with a bent subsection of the sort normally used in drilling a borehole which deviates from the vertical. The downhole element of the invention consists of a subsection which is affixed in the drill stem in the vicinity of the drill bit, and preferably immediately above the drill bit. In one embodiment of the invention, the downhole subsection includes one or more recessed chambers which define a flat faces parallel to the longitudinal axis of the subsection at the interior which is immediately adjacent to a relatively thin portion of the wall of the subsection. The thin portions or "diaphragms" are stressed as the subsection is loaded by forces in the vicinity of the drill bit. The diaphragms acts as collectors for the discrete strains generated by the nominally squared discontinuities. Consequently, strain gauges affixed to the one or more diaphragms provide output signals proportional to stress from which various force components can be uniquely determined.

Abstract: A band division process including a Fourier transformation is performed for an inputted speech signal, thereby outputting spectrum signals of plural channels. A cepstrum analysis process is performed for the spectrum signals, and a peak of the obtained cepstrum is detected in response to the cepstrum analysis result. Thereafter, a speech signal interval the inputted noisy speech signal is detected in response to the detected peak, and a noise is predicted in the speech signal in response to the detected speech signal interval. Then, the predicted noise is canceled in the spectrum signals thereby outputting noise-suppressed spectrum signals. Finally, the noise-suppressed spectrum signals are combined and are inverse Fourier-transformed, thereby outputting a noise-suppressed speech signal.

Abstract: A pattern recognition system includes at least one pair of basic associative units each having at least first and second unit ports for receiving pattern signal groups, respectively and a third unit port for outputting a pattern signal group. The pattern recognition system has characteristics of the type of pattern recognition carried out by living organisms. Each of the basic units operates to derive weighting values for respective signals of the pattern signal groups inputted to the first and second unit ports of the basic unit itself in accordance with the degree of consistency between a previously given weighting pattern and respective patterns specified by the pattern signal groups inputted to the first and second unit ports of the basic unit itself. Each of the basic units also operates to modulate the respective signals of the pattern signal groups inputted to the first and second unit ports of the basic unit in accordance with the derived weighting values and to totalize the modulated signals so as to form an output signal outputted form the third unit port of the basic unit itself. The third unit port of one of the basic unit pair is coupled to the first unit port of the other basic unit, and the third unit port of the other basic unit is coupled to the second unit port of the one basic unit. Thus, the third unit port of one of the basic unit pair gives an recognition output.

Abstract: The signal to be classified is sampled and the samples are multiplied by weighting functions prior to performing discrete Fourier transforms, power calculations, and normalization thereon so that the preprocessor is essentially a plurality of channel bandpass filter stages, the k-th one of which has a frequency response approximating an ideal filter defined by ##EQU1## where k=O, .alpha., 2.alpha., 3.alpha., . . . , r.alpha..alpha.=constant, 1.ltoreq..alpha..ltoreq.N/2r+1=greatest integer in N/.alpha.This preprocessor transforms blocks of one dimensional data into spectra in such a way that data blocks coming from similar sources will have spectra that are close to one another in spectrum space. The discrete Fourier transform is modified to remove or reduce the phase dependency problem and to enhance the clustering of similar spectra by the weighting function above.

Abstract: A piezoresistive force-measuring element comprises at least two force-introduction plates with an electrical conductor subjected to plastic deformation arranged between them. The force-introduction plates transmit the forces acting on them without mechanical shunting onto the conductor between them. The change of electrical resistance caused by the force sustained can be used to measure force, accompanied by plastic as well as elastic deformation of the conductor. The typically annular or rectangular force-introduction plates can be fitted inside a housing which may include a bridge circuit for determining the resistance change as well as other electronics enabling the device to be used as a transmitter. By placing the conductor in grooves or anchoring it in the pores of the adjacent plates, an essentially hydrostatic loading of the conductor is obtained, bringing an enormous extension of the measuring range while the measuring accuracy is enhanced owing to the reduced hysteresis. The sensitivity and the measuring range can be adjusted by appropriate prior deformation of the conductor. Permanent deformation of the conductor resulting from high loads makes possible subsequent determination of the magnitude of the peak forces acting on the measuring element.

Abstract: A device for monitoring the fatigue life of a structural member is comprised of at least one and preferably a plurality of substantially flat, elongated coupons which are fabricated of the same material as that of the member being monitored. The coupons are secured in parallel to the member so that they all experience the same strain history as the member. Each of the coupons includes a different stress concentrating notch pattern so that the application of the same strain to all of the coupons results in the development of different stress concentrations within the coupons. The development of different stress concentrations within the coupons causes each coupon to have a different fatigue life, the fatigue life of each coupon being a predetermined percentage of the fatigue life of the structural member being monitored.

Abstract: A test bearing is adapted from a standard production bearing for recording the location and magnitude of load applied to the bearing when installed and operated in its intended environment. A groove is typically formed in the stationary raceway of a cylindrical or tapered roller bearing and a relatively soft ductile wire is inserted into the groove. A plurality of axially spaced circumferential grooves may be fitted with wires for the determination of any potentional misalignment of the bearing. The bearing is then operated under normal conditions such that the inserted wires are plastically deformed. The extent of plastic deformation of the wire provides an accurate indication of the loading of the bearing.
