A sensor package for sensing rotational positional data includes a stack of separated printed circuit boards that includes a first position target printed board, a second printed circuit board having a rotary sensor and a third printed circuit board having power supply components. The sensor package is included in a skew detection system for an aircraft control system, which includes a control surface having opposed first and second ends. A first drive mechanism is operatively connected to the first end of the control surface by a first rack and pinion assembly and a second drive mechanism is operatively connected to the second end of the control surface by a second rack and pinion assembly. Each rack and pinion assembly includes a respective sensor package operatively connected to the pinion thereof. A processing component is operatively connected to both sensor packages to determine presence of skew in the control surface.

A capacitive touch sensor wherein the touch sensitive panel has drive electrodes arranged on the lower side of a substrate and sense electrodes arranged on the upper side. The drive electrodes are shaped and dimensioned to substantially entirely cover the touch sensitive area with individual drive electrodes being separated from each other by small gaps, the gaps being so small as to be practically invisible. The near blanket coverage by the drive electrodes also serves to screen out interference from noise sources below the drive electrode layer, such as drive signals for an underlying display, thereby suppressing noise pick-up by the sense electrodes that are positioned above the drive electrodes.

One example includes a position sensing system. The system includes an inductive position element that is moveable and comprises a position inductor. The system also includes a plurality of inductive load elements. Each of the inductive load elements includes a load inductor. Each of the plurality of inductive load elements can be selectively controlled in response to a modulation signal to provide a corresponding mutual inductance between the position inductor and the respective load inductor, the corresponding mutual inductance depending on a position of the inductive position element relative to the respective load inductor. The system further includes a position controller configured to generate the position and modulation signals and to calculate the position of the inductive position element relative to the plurality of inductive load elements based on a difference of the position signal with respect to the mutual inductance between the position inductor and each respective load inductor.

A position sensor system is useful for monitoring positions of shifters in transmissions and other applications. The position sensing system has an array of magneto resistive sensors and a controller configured to determine a position of a magnet along a path by triangulation. Some embodiments are relatively insensitive to fluctuations in a distance between the sensors and the path. Also described is an actuating assembly comprising a movable cylinder and a fixed rod. The actuating assembly may be applied for moving synchronizers or the like in power transmissions.

A rotation angle detector has a rotation angle sensor and a microcomputer, where the sensor detects a change of a magnetic field of a magnet that rotates with a shaft. The microcomputer has a first corrector for correcting a pre-correction mechanical angle, based on a first correction value that corrects an error due to an assembly process for assembling the magnet and the sensor, and a second corrector for correcting the pre-correction mechanical angle based on a second correction value that corrects an error due to a spill magnetic flux that is generated by a supply of an electric current to a winding wire. In such configuration, the rotation angle detector may correct the error due to the spill magnetic flux, thereby enabling an accurate detection of a mechanical angle.

There is provided a displacement sensor which can precisely detect the amount of displacement given by an operator. A touch sensor which is a type of the displacement sensor has a piezoelectric element, a voltage converting unit and a detecting unit. The piezoelectric element instantaneously generates a voltage proportional to a pressing force (the amount of pressing). The voltage converting unit converts the voltage generated by the piezoelectric element, into a voltage proportional to a transition determined based on a predetermined time constant determined by an impedance of a resistor of the voltage converting unit and capacitances of a capacitor and the piezoelectric element, and a pressing force. The detecting unit integrates output voltages of the voltage converting unit, and calculates the pressing force (the amount of pressing) based on an integration value.

A method is provided for precisely enlarging a nanopore formed in a membrane. The method includes: applying an electric potential across the nanopore, where the electric potential has a pulsed waveform oscillating between a high value and a low value; measuring current flowing though the nanopore while the electric potential is being applied to the nanopore at a low value; determining size of the nanopore based in part on the measured current; and removing the electric potential applied to the membrane when the size of the nanopore corresponds to a desired size.
