Abstract: A system, method and article of manufacture are provided for detecting collisions or any other type of interactions between video images and an object depicted on a display. First, video images generated by a camera are received. Upon receipt, a first collision detection operation is executed for generating a first confidence value representative of a confidence that the received video images have collided with an object depicted on a display. Also executed is a second collision detection operation for generating a second confidence value representative of a confidence that the received video images have collided with the object depicted on the display. The first confidence value and the second confidence value are then made available for various applications. Such applications may depict an interaction between the video images and the object depicted on the display based on the first confidence value and the second confidence value.

Abstract: A muffling device for use on the exhaust of an electric generator engine includes an arrestig chamber, partitioned into two compartments by means of an apertured partition. The first compartment is packed with stainless steel wool to filter out hot particulates from the exhaust of the generator engine. The filtered exhaust gases pass through the apertures into the second compartment from where they are directed to the atmosphere by means of a tubular member connected in said second compartment. A muffling chamber is connected directly to the exhaust of the electric generator engine and the exhaust gases first flow into that chamber. A cross-over conduit is in fluid communication with both chambers and directs the exhaust gases from the muffling chamber into the first compartment of the arresting chamber.
