Abstract
Official abstract text for this publication.
A pixel array system for high accuracy detection of displacement, speed and acceleration includes: an array comprising m columns and n rows, wherein at least every other row is offset with respect to a preceding row of the array. In a first embodiment, every other row is offset with respect to a preceding row of the array by 25% of a pixel width. In a second embodiment, every two rows are offset with respect to a preceding two rows of the array by 25% of a pixel width.
First claim
Opening claim text (preview).
What is claimed is: 1. A pixel array system for high accuracy detection of displacement, speed and acceleration, comprising: an array comprising a plurality of pixels, each pixel touching at least one other pixel in a same row and touching at least one other pixel in a different row, wherein at least one row is offset with respect to a preceding row of the array by less than 50% of a pixel width, the array for receiving an input from an object passing over at least the offset row and the preceding row, and detecting displacement, speed and acceleration of the object when said object passes less than 50% of a column of the array, in order to generate an output representing at least one of the detected displacement, speed and acceleration of the object. 2. The pixel array system of claim 1 , wherein at least every other row is offset with respect to a preceding row of the array. 3. The pixel array system of claim 2 , wherein every row is offset with respect to a preceding row of the array. 4. The pixel array system of claim 3 , wherein every row is offset with respect to a preceding row of the array by 25% of a pixel width. 5. The pixel array system of claim 2 , wherein every two rows are aligned with respect to each other, and every two rows are offset with respect to a preceding two rows of the array. 6. The pixel array system of claim 5 , wherein every two rows are offset with respect to a preceding two rows of the array by 25% of a pixel width.
