摘要： A position-sensing system includes a first component (e.g., a cylinder) and a second component (e.g., a piston rod) movably coupled to the first component for movement with respect thereto. A magnetically hard layer on the second component provides a recording medium. Regions of the magnetically hard layer are magnetized as magnetized rings around the second component. Magnetic-field sensors are coupled to the first component in proximity of the magnetically hard layer on the second component to sense the rings of magnetized regions. Each of the magnetic field sensors senses flux from each of the rings of magnetized regions as the second component is moving with respect to the first component and, in response to sensing the rings of magnetized regions, generates signals used to determine position of the second component.

摘要： A rotary encoder comprising a magnet, AMR or GMR sensors and an evaluation means. The AMR or GMR sensors are arranged to generate two signals that unambiguously encode the rotary position of the magnet within a predetermined range of rotary positions and a direction of rotation of the magnet. The evaluation means is arranged to derive single-turn and multi-turn information solely from the signals. The encoder is arranged to be switched to a power saving state for a predetermined period of time, to be at least partially reactivated thereafter and to compare a current value derived from the signals with a stored previous value derived from the signals.

摘要： A position-sensing system magnetically senses the position of a piston rod moving with respect to a cylinder. A magnetically hard layer on the piston rod provides a recording medium. Information is perpendicularly magnetized in regions of the magnetically hard layer. These regions provide an encoding scheme for determining the position of the piston rod. Magnetic-field sensors are positioned over redundant tracks of magnetically recorded regions. Each magnetic-field sensor positioned over a given track senses the same magnetized regions while the piston rod moves with respect to the cylinder. Other magnetic-field sensors can sense ambient fields for use in performing common-mode rejection. A write head can dynamically repair damaged or erased regions detected by the magnetic-field sensors. Energized by a battery-backup power source, the magnetic-field sensors and associated circuitry can continue to track movement of the piston rod when the machinery is off.

摘要： In the magnetic absolute encoder, an ordinary operating circuit and an ordinary/backup operating circuit are actuated during ordinary operation in which power is supplied from the ordinary operating power supply; the single-rotation absolute value (1) and single-rotation absolute value (2) detected by these circuits are compared by the abnormality diagnosis circuit, and the presence or absence of an abnormality is automatically judged During backup in which the ordinary operating power supply is interrupted, only the low-power-consumption ordinary/backup operating circuit is actuated, and the multiple-rotation value (2) is detected At the point in time at which the system is returned to ordinary operation, the multiple-rotation value setting circuit sets the multiple-rotation value (2) as the multiple-rotation value (1) of the ordinary operating circuit. As a result, the calculation operation of the multiple-rotation value (1) can be restarted.

摘要： A position-sensing system magnetically senses the position of a first component moving with respect to a second component. A magnetically hard layer on the first component provides a recording medium. Information is magnetically recorded in regions of the magnetically hard layer. These regions provide a relative encoding scheme for determining the position of the first component. Magnetic-field sensors are positioned over redundant tracks of magnetically recorded regions. Each magnetic-field sensor positioned over a given track senses the same magnetized regions while the first component moves with respect to the second component. Other magnetic-field sensors can sense ambient fields for use in performing common-mode rejection. A write head can dynamically repair damaged or erased regions detected by the magnetic-field sensors. Energized by a battery-backup power source, the magnetic-field sensors and associated circuitry can continue to track movement of the first component when the machinery is off.

摘要： In a position detector for detecting a position of a detection body, a signal processing circuit processes a signal outputted from a magnetic field detection element. A first storage circuit stores the signal outputted from the magnetic field detection element and outputs a signal to an external device through an output circuit in a normal operation mode. A second storage circuit stores an output value of the first storage circuit. When a malfunction determination circuit determines an instantaneous power interruption mode, a signal route changing circuit prevents a signal transmission between the first storage circuit and the second storage circuit and a signal transmission between the first storage circuit and the output circuit, prevents the second storage circuit from updating data for a certain period of time, and permits the second storage circuit in which updating is prevented to output a signal to the output circuit.

摘要： A digital sensor has a sensor element, a digital section, a sample-and-hold stage and an output stage, and storage storing electrical energy, each of which are supplied with electrical energy by a power supply. In the event of a failure of the power supply, the sample-and-hold stage and the output stage are provided with power by the storage storing electrical energy, such that the measurement value most recently stored in the sample-and-hold stage is provided in the signal line by the output stage until the failure of the power source has ended and a new measurement value is stored in the sample-and-hold stage. No electric power is supplied to the sensor element by the storage storing electrical energy in the event of a failure of the power supply.

摘要： A position-sensing system magnetically senses the position of a piston rod moving with respect to a cylinder. A magnetically hard layer on the piston rod provides a recording medium. A track comprised of a plurality of magnetized regions is magnetized in the magnetically hard layer. A plurality of magnetic-field sensors is coupled to the cylinder in proximity of the magnetically hard layer to sense the magnetized track while the piston rod is moving with respect to the cylinder. A first one of the magnetic field sensors is positioned over the track to sense the magnetized regions of the track serially and a second one of the magnetic field sensors is positioned radially to one side of the track. The magnetic field sensors generate signals, in response to sensing the magnetized regions, for use in measuring rotational movement of the piston rod.
