Abstract: The present invention relates to a horseshoe having a toe end, a heel end opposite the toe end, a top surface that spans between the heel end and the toe end, and a bottom surface that spans between the heel end and the toe end, wherein the top surface tapers toward the bottom surface from the heel end to the toe end.

Abstract: The image processing system includes an image processor performing adaptive pixel segmentation for a sequence of image frames collected during movement relative to a scene, with each image frame having a plurality of pixels. An image sensor collects the sequence of image frames while moving relative to the scene. The image processor may perform the adaptive pixel segmentation by generating a probability density function (PDF) for pixels based upon a plurality of past image frames from the sequence thereof, determining whether pixels in a new image frame from the sequence thereof are independently moving pixels or background pixels based upon comparing the new image frame to the at least one PDF, and updating the at least one PDF based upon the new image frame.

Abstract: The present invention is a method of determining the time of arrival of an incident signal transmitted utilizing a code word that is interspersed with noise and diffracted and reflected signals of the incident signal. The incident, diffracted and reflected signals and noise are collectively defined as a combined signal. The method comprises receiving the combined signal; obtaining the code word to apply to the combined signal; comparing the combined signal with the code word to filter the incident signal and diffracted and reflected signals arising from the incident signal from the combined signal; utilizing the incident signal and related diffracted and reflected signals to determine a first parameter indicative of the incident signal's time of arrival; and filtering the first parameter utilizing a multipath mitigation algorithm to mitigate the influence of the diffracted and reflected signals to obtain a second parameter indicative of the incident signal's time of arrival.
