Implementations relate to a sensor assembly for determining rotation about an axis and linear movement parallel to the axis. The sensor assembly comprises a magnetic structure comprising a north pole radially displaced from the axis and a south pole radially displaced from the axis and opposite to the north pole. The north pole and the south pole of the magnet extend radially into the direction of the axis at an axial end of the sensor assembly. The sensor assembly further comprises at least one sensor element sensitive to magnetic fields radially between the north pole and the south pole.

Provided are a data processing device, etc. that makes it possible to measure an object between adjacent positions where measurement instruments are installed. A data processing device comprises: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to acquire, from each measurement instrument installed at different measurement positions, measurement data indicating results of measuring an object, to acquire sensing data from an optical fiber cable laid so as to pass through each of the different measurement positions, and to use the sensing data to interpolate measurement data.

A position detection device for detecting a position of a shaft moving forward and backward in an axial direction is provided with a detection object mounted on the shaft, a substrate disposed to face the detection object, an excitation coil that is mounted on the substrate and generates an AC magnetic field, a detection coil that is mounted on the substrate and arranged along the axial direction of the shaft and configured so that a magnitude of a voltage induced varies with a position of the detection object, and a sensor for detecting a physical quantity used to correct the position of the shaft by using a sensor coil configured by the excitation coil, the detection coil, or an other coil provided on the substrate.

A sensor system includes at least one transmitter; a receiver circuit; and a metamaterial layer having a relative position that is configured to vary relative to the transmitter. The metamaterial layer includes an array of elementary structures arranged within a coordinate system of the metamaterial layer. The array of elementary structures includes a first metamaterial characteristic that changes along a first coordinate variation of the coordinate system and a second metamaterial characteristic, different from the first metamaterial characteristic, that changes along a second coordinate variation of the coordinate system. The at least one transmitter is configured to transmit an electromagnetic transmit wave toward the metamaterial layer. The metamaterial layer is configured to convert the electromagnetic transmit wave into an electromagnetic receive wave based on the relative position. The receiver circuit is configured to receive the electromagnetic receive wave and determine the relative position based on the electromagnetic receive wave.

A position detection device for detecting a position of a rack shaft having a rack teeth portion that meshes with a pinion gear in a part in an axial direction, is provided with a capacitance member that is arranged around a periphery of the rack shaft and forms a capacitive load together with the rack shaft, and a calculation unit that calculates the position of the rack shaft based on a capacitance between the rack shaft and the capacitance member. The capacitance member is arranged to face at least a part of the rack teeth portion. The capacitance changes in accordance with the position of the rack shaft.

An input device includes an operation nob configured to perform a rotation operation and a push operation; one magnet provided so as to perform a rotational movement in response to the rotation operation and to perform a sliding movement in response to the push operation, from an initial state; a magnetic sensor disposed on a substrate and configured to detect a magnetic field generated by the magnet; and circuitry configured to determine operation contents of the rotation operation and the push operation based on a detection result of the magnetic sensor, wherein the magnet is disposed such that a rotation axis serving as a rotation center when performing the rotational movement passes through the magnet, and magnetization directions of an N pole and an S pole of the magnet are inclined with respect to the rotation axis of the rotational movement and a direction of the sliding movement.

The linear measuring system includes one part of a (usually steel) rod, beam or strip that is profiled with a trapezium like (subset of a) De Bruijn sequence. Each element of the alphabet is represented by a discrete height of the profile. The profile can be coated with a material with low magnetic susceptibility to enable the application on a piston rod of a pressure medium cylinder. The second part of the measuring system reads the subsequences of the main sequence by using the signals of arrays of linear Hall effect sensors, placed in a magnetic field as input for a signal processing algorithm. With a look-up table, the position of this second part of the measuring system with respect to the profile is determined. An interpolation algorithm can be used to improve the resolution to well below the sequence pitch.

A dispensing pump having a calibration system including a base including an upper base portion having a first end for mounting a motor and a second end and a lower base portion for mounting a pump on a first end and a second end. A hinge pivotally connects the second end of the upper base portion and the second end of the lower base portion. A linear actuator is mounted on the base and includes a drive rod having a coupler secured to an end thereof. The coupler joins the drive rod to a first end of a connecting member. A second end of the connecting member is secured to the lower base portion. An attachment plate attaches the motor to the first end of the upper base portion. The attachment plate extends outwardly from the motor for mounting the linear actuator. A proximity sensor is secured to the base upper position. A flag is secured to the drive rod coupler, wherein the flag moves directly with the drive rod. The flag includes a body and a calibration element projecting therefrom. The calibration element is positionally adjustable relative to the flag body. The calibration element is adapted to activate the proximity sensor when the linear drive is in a home position. The home position is adjustable upon adjustment of the calibration member. An actuation of the linear actuator drives the connecting member causing the lower base portion and upper base portion to pivot with respect to each other about the hinge, thereby changing an angle between the lower base portion and the upper base portion.
