Abstract: An object detection system is provided that projects one or more patterns onto a monitored area, captures one or more live images of the monitored area, and detects objects that enter the monitored area by detecting changes in the one or more patterns in the live images. Such an object detection system may be less susceptible to dynamic lighting conditions, and more sensitive to object intrusions. One illustrative example projects a pattern of dots onto an area to be monitored, and captures images corresponding to the monitored area, comparing live images to reference images to determine whether an object has intruded a defined area. The area to be monitored does not consist solely of the area captured in the images and may include a volume illuminated by the pattern as well as a volume corresponding to the captured image area. Objects not in the field of view may be detected by the disclosed systems and methods. Several illustrative analytical methods are disclosed as well.

Abstract: Scheduling a set of anytime tasks includes assigning a percentage of at least one resource to each of the set of anytime tasks and allowing each of the set of anytime tasks to use the at least one resource in accordance with the respective assigned fraction. The percentage of the at least one resource assigned to each of the set of anytime tasks is subsequently adapted.
