  • Method of separating vertical and horizontal components of a rasterized image
    Patent number: 7835583
    Abstract: A method of separating an image is provided. The method comprises: running a bitmap image of at least one polygon comprising a plurality of pixels through a distance filter; skeletonizing the polygon formed after filtering by modulo arithmetic; logically ANDing the skeletonized image with two masks separately consisting of horizontal and vertical lines of 1 bit thickness at a particular frequency to form an image of the horizontal edges and an image of the vertical edges; and filtering the resulting image through a particle filter eliminating particles of size greater than 2.
    Type: Grant

  • Method and apparatus for scavenging and using energy caused by changes in pressure
    Patent number: 7178389
    Abstract: An apparatus to scavenge energy caused by changes in interior pressure of a container, including at least one flexible chamber containing a fluid at a predetermined pressure; a piezoelectric element coupled to the flexible chamber so as to generate electricity when the flexible chamber is flexed by a change in interior pressure of the container.
