Abstract: A system comprises a rotatable object having a pseudo-random pattern of overlapping rounded shapes on an outer surface of the rotatable object and an image sensor configured to capture an image of a portion of the pseudo-random pattern on the outer surface. The system also comprises a memory configured to store a pattern map corresponding to the pseudo-random pattern on the outer surface of the rotatable object; and a processing unit configured to correlate the portion of the pseudo-random pattern in the captured image with a corresponding portion of the pattern map stored on the memory.

Abstract: Methods and systems for improving frequency estimation without increasing digital counter resolution. An example system mixes and filters a known carrier signal with the signal containing the frequency of interest, in order to bring the frequency domain image closer to baseband, and then performs the frequency estimation. This allows much better resolution without the need to increase the counter frequency.

Abstract: Systems and methods are provided for detecting a movement of an object marked with a marker. The system includes a sensor configured to capture a first image of the marker and to capture a second image of the marker after the first image, each of the first and second images having pixels each having a visual intensity. A controller is configured to compare the first image and the second image by comparing the visual intensity of each of the pixels of the first image and the second image, determine an area of overlap between the first image and the second image based on the comparison, calculate a change in position of the marker in the second image relative to the marker in the first image based on the area of overlap, and detect the movement of the object based on the change in position of the marker.
