Abstract: A method for determining absolute value of a rotational angle includes imaging a segment of a code track onto a sensor such that the sensor generates a corresponding output signal. The track includes a code in the form of a light and dark transition pattern over an angular range. The code contains code words with each code word corresponding to a respective angular value. The code word of the imaged segment is determined from the position of the transitions in the output signal to determine the angular value of the imaged segment. The position of the transitions in the output signal is compared with a reference curve to determine position deviations between the output signal and the reference signal. The reference curve represents the transitions expected in the output signal in the absence of unwanted mechanical influences. The unwanted mechanical influences are determined as a function of the determined deviations.

The shaft is connected at a true angle of rotation to a material measure and is divided axially into a drive section (10), which can be coupled to the measured object, and an output section (12), which is connected to the material measure. The drive section (10) and the output section (12) are connected in torsionally rigid but axially resilient fashion by an intermediate element (26), which takes the form of a disk.

Abstract: Since an abnormality is judged by executing a square calculating process with respect to sin θ and cos θ for detecting an abnormality in an angular resolver, a processing time is elongated, and a burden to a CPU is great. Since the invention prepares a map which can judge whether the combination of sin θ and cos θ is normal or abnormal, and judges by mapping the combination of the detected sin θ and cos θ, a process can be easily executed, a processing speed is high, and a burden to the CPU can be reduced. Further, an assist can be maintained by controlling a motor by a rectangular wave current by detecting a rotation angle signal at low resolution level, such as Hall sensors arranged around the motor.

Abstract: A position-measuring circuit is described for use with an analog position encoder of the kind comprising a code member and at least two sensors for sensing successive marks on the code member during relative movement between the code member and sensors, the sensors providing two oscillating quadrature signals. The circuit comprising means for obtaining a relatively coarse measure of position by detecting successive instants t0–t3 at which the amplitudes of the sensor signals are equal or at which the amplitude of one signal is equal to the inverse of the amplitude of the other signal. The amplitude of one of the signals or its inverse is stored at each detection instant to alternately establish relatively high and low threshold levels. A fine measure of position at an arbitrary instant T is obtained as a function of the instantaneous amplitude P of one of the signals and the difference between neighbouring high and low thresholds levels.

Abstract: A transducer, a method and a coding pattern for determining a kinematic measurable variable are disclosed. A transducer comprises a first device part which is moveable in or through a corresponding device for oil or natural gas production and a second device part which is stationary relative to said first device part. To detect both the directions of movement and the respective position in a simple constructional and inexpensive way without the need for return movement up to ends of the range of movement, the first and/or second device part comprises a coding pattern which is changing along a direction of movement and of which position-specific patterns can be scanned by a scanning means which is arranged on the respective other device part. By scanning such a specific coding pattern during mutual relative movement of said objects or device parts a corresponding scanning signal can then be converted by an evaluation unit into a kinematic measurable variable. The corresponding coding pattern comprises a plurality of single patterns wherein neighboring single patterns differ from one another by at least one characteristic feature and/or said single pattern has at least one characteristic feature that is changing in the direction of movement.

Abstract: In an optical disk apparatus, the polarity of synchronization information is adaptively set to thereby improve the quality of data recording and reproduction. When inserting and recording synchronization information, an encoder of an optical disk apparatus temporarily sets the polarity of the synchronization information to either a mark or a space in accordance with a predetermined rule. A DSV which is obtained if the synchronization information is to be recorded with the polarity which has been temporarily set is computed. If the DSV which is computed is equal to or smaller than a predetermined limit value, the polarity which has been temporarily set is accepted and the synchronization information is actually recorded with the polarity. If the DSV which is computed exceeds the limit value, on the other hand, the polarity which has been temporarily set is not adopted, and the synchronization information is actually recorded with a polarity which is different from the polarity.
