Abstract: A system for controlling a motor may include a motor driver circuit for driving a camera motor. A memory capable of storing a plurality of parameters for controlling the camera motor may also be included. A set of parameters from the memory may be chosen to be applied to driving the motor. A motor control module may receive a signal from the control logic module, apply the chosen set of parameters to driving the camera motor, and command the motor driver circuit to drive the motor in accordance with the applied set of parameters. The parameters may be chosen based on desired behavior of the system and various other stimuli.

Abstract: Methods and apparatus for determining the temperature of a pixel array. In embodiments, a first pixel in a pixel array is reverse-biased and a second pixel in the pixel array is forward-biased. A voltage for the second pixel can be measured to determine a temperature of the pixel array from the measured voltage for the second pixel.

Abstract: Methods and apparatus for temperature sensing in a detector system. Dark current from pixels in a pixel array of the detector system can be filtered to remove noise and processed to determine a temperature of the pixel array from the filtered dark current. Calibration of the dark current for a range of temperatures can be performed. In embodiments, the pixels comprise photodiodes.

Abstract: Methods and apparatus for sensing target position by generating a signal by energizing a shaped coil with an AC signal. A sensor receives a signal reflected by a target in response to the signal from the shaped coil, wherein the shaped coil has a first width, and wherein the sensor includes a first sensing element aligned with the shaped coil at the first width, wherein a ratio of the first width and a distance from the sensor to the target is about three-to-one. The received signal can be processed to determine position information of the target. In some embodiments, a shaped coil can have a trapezoidal shape and sensors aligned with the coil to select a sensor based upon target to sensor distance.

Abstract: A pressure sensor comprises a deformable substrate, at least one coil supported by the substrate and responsive to a changing coil drive signal to produce a changing magnetic field, a fluid chamber having a first wall formed by the substrate and a second wall formed by a conductive material and positioned proximate to the at least one coil so that the changing magnetic field produces eddy currents within the conductive material that generate a reflected magnetic field, and at least one magnetic field sensing element configured to detect the reflected magnetic field and produce a signal responsive to a distance between the magnetic field sensing element and the second wall. The substrate is deformable by fluid pressure within the fluid chamber and the deformation of the substrate changes the distance between the magnetic field sensing element and the second wall.
