Abstract: A sensor assembly that includes a sealed housing. A printed circuit board assembly including a first section that includes processing circuitry is disposed within the sealed housing and a second section that includes detection circuitry extends from the sealed housing. The sensor assembly also includes a conductive target movably coupled to the second section of the printed circuit board to vary net voltage of the detection circuitry as the conductive target moves along the second section to provide an output signal. The processing circuitry detects the output signal and converts the output signal into a linear representation of position of the conductive target in relation to the second section.

Abstract: A display with a first emissive image and a second image. The display includes a waveguide that includes an image formed from photoluminescent dyes on a surface of the waveguide which is activated by a first light source. A second light source behind said waveguide produces a second image. A light filter is positioned between the waveguide and the second light source. The second light source can illuminate a transparency, such as a translight, or a physical object providing an image that is viewable from the display when the second light source is illuminated and the first light source is not illuminated. The first image is viewable when the first light source associated with the waveguide is activated, emitting, for example, an ultraviolet light that activates the photoluminescent dyes, causing the first image to be viewable.

The first waveguide 14 that receives the light from the remotely positioned light source 12. The second waveguide 16 is disposed at an angle relative to the first waveguide 14. The second waveguide 16 includes a photoluminescent printed image 18. The first propagation direction changing feature 20 reorients the direction of the light into the second waveguide 16, making image 18 visible.

Abstract: A sensor assembly includes a housing, a shield member, a magnetic field sensor, and a sensing magnet. The housing is configured to be mounted at least proximate to an electromagnetic coil that generates a first magnetic field to cause a movable component to move linearly along an axis based on the strength of the first magnetic field. The sensing magnet is configured to be coupled to the movable component to move therewith. The magnetic field sensor and the sensing magnet are disposed within a shielded chamber defined by the shield member, which is ferrous to shield the magnetic field sensor and sensing magnet from the first magnetic field. The magnetic field sensor detects an electrical characteristic responsive to a second magnetic field produced by the sensing magnet to monitor a position of the movable component along the axis.

Abstract: High-resolution multi-turn sensing apparatus and methods. A method can be implemented to sense a rotational position of a shaft having a longitudinal axis. Such a method can include determining a turn number of the shaft with a first magnet arranged in a non-contact manner with a first magnetic sensor to allow measurement of a linear position of the first magnet relative to the first magnetic sensor. The linear position can be representative of a turn number of the shaft. The method can further include determining an angular position of the shaft within a given turn with a second magnet positioned at an end of the shaft along the longitudinal axis and arranged relative to a second magnetic sensor. The method can further include combining the turn number with the angular position to generate one or more output signals representative of a measured rotational position of the shaft.

Abstract: Disclosed are systems and methods for measuring multi-turn position of a shaft with high resolution and in a non-contact manner. In some embodiments, a multi-turn sensing apparatus can include a rotation counter configured to determine a number of turns made by a shaft, and an angular position sensor configured to measure an angular position of the shaft within a given turn. The number of turns can be determined with an M-bit resolution, and the angular position per turn can be measured with an N-bit resolution. Selected appropriately, the rotation counter can be configured to operate as a relatively low resolution; and yet the multi-turn sensing apparatus can maintain the N-bit per-turn angular resolution throughout the full range. Accordingly, the multi-turn sensing apparatus can have an effective resolution of M+N bits.
