Title: System and method for median fusion of depth maps
Inventor: NISTER DAVID
IPC: G06T7/00
Filed: 2001-06-28
Abstract: The present invention is directed toward providing a system for constructing a graphical representation of an image, as perceived from a desired view, from a plurality of calibrated views. An optimum, median fused depth map of a new, desired view of an object or a scene is constructed from a plurality of depth maps of the object or scene, utilizing median values for each of the image pixels within the image domain of the new view. Each of the known depth maps are rendered into the new view, and the pixels of the rendered image are processed one at a time until a median value for each pixel in the new view of the image of the object or scene is calculated. The calculated median values are then assembled into a median fused depth map of the new view of the object or scene, with the median fused depth map available to construct a new two or three dimension images and models of the object or scene as perceived from the new view.

Title: Method to combat apple worm
Inventor: ANGELOVA RADA G
IPC: A01N25/00
Filed: 1990-03-20
Abstract: The method is applied in fruit growing. When using it, treatment against apple worm third generation and preliminary preventive treatments are not necessary whereby fruit and useful entomo and acarifauna are better preserved. The method helps to prognosticate more precisely and more objectively the moments of treatment against apple worms first and second generation with inhibitors of the chitinous synthesis by structuring the flight period. The optimum moment for treatment against the apple worms first generation is determined at reaching 5 per cent flight, temperature 11 degrees C and a total of effective temperatures equal to 51.7 degrees C, and against the second generation - at reaching 2 per cent flight, lower temperature limit of 18 degrees C and a total of effective temperatures equal to 53 degrees C

Title: Valve gated sequential injection molding apparatus
Inventor: SCHMIDT HARALD H
IPC: B29C45/16
Filed: 1990-02-19
Abstract: ABSTRACT OF THE DISCLOSURE         Valve gated hot runner molding system or apparatus for sequentially injecting different types of fluid or plastic melt into a cavity.  A valve member is reciprocated between forward closed and retracted open positions in a central bore in a heated nozzle. Separate channels convey the different types of melt from different molding machines to angularly spaced outlets to the central bore near the forward end of the nozzle.  The valve member is rotated by rack and pinion mechanism between corresponding angular positions.  The valve member has a longitudinal groove near the forward end which connects one of the melt channel outlets to a larger diameter bore adjacent the gate when the valve member is retracted to the open position.  After the first type of material partially fills the cavity around the outside, the valve member is rotated to fill the middle of the cavity with another type of material.  The different channels join adjacent where the valve member closes the gate so there is no residual material from the wrong channel after each shot.
