摘要： A method for testing cameras includes positioning a camera such that an image of a target is displayed on a monitor within at least one default image parameter. The method further includes engaging a dimming condition of a light source from the camera, thereby generating a lighting condition signal. Subsequently the camera receives the lighting condition signal and displays it on the monitor. A group of observers then analyze the lighting condition signal. The method continues through engaging a second dimming condition of the light source from the first camera, thereby generating a second lighting condition signal, which is also displayed on the monitor. The group of observers then analyzes the second lighting condition signal.

摘要： A measurement system (10) for accurately measuring the surface geometry of a part (32) in three dimensions includes a laser (12) for emitting a laser beam (14). The laser beam (14) is transmitted to a birefringent crystal (16) which splits the laser beam (14) into a pair of beams (18,20). The pair of beams (18,20) are then subjected to a phase shift by a liquid crystal system (24) as controlled by a computer (26). The pair of beams (18,20) are then expanded in order to form a fringe pattern (30) on the surface of the part (32) to be measured.

摘要： A blind spot monitoring system for a vehicle includes two pairs of stereo cameras, two displays and a controller. The stereo cameras monitor vehicle blind spots and generate a corresponding pair of digital signals. The display shows a rearward vehicle view and may replace, or work in tandem with, a side view mirror. The controller is located in the vehicle and receives two pairs of digital signals. The controller includes control logic operative to analyze a stereopsis effect between each pair of stereo cameras and the optical flow over time to control the displays. The displays will show an expanded rearward view when a hazard is detected in the vehicle blind spot and show a normal rearward view when no hazard is detected in the vehicle blind spot.

摘要： A closed core box is provided with one or more inlets for receiving and passing gas fluidized resin-coated sand to fill the interior of such core box, and with one or more screened outlets for allowing egress of such gas. A closed cylindrical or angular sand-fluidizing chamber is provided for each of the inlets, the chamber having one end connectable to a pressurized gas supply and an opposite end communicating with an inlet. At least part of each chamber is filled with resin-coated sand and a non-porous piston is placed on the sand within each chamber, each piston providing an annular gap (i.e. about 1/16 of an inch) with the interior of such chamber to direct the gas supply along the periphery of the chamber interior. The pressurized gas supply (40-80 psi) is connected to the chamber above the pistons whereby gas will move past each of the pistons to fluidize the sand therebelow in the chamber in a manner that continuously and toroidally recirculates the sand away from the periphery of the chamber while communicating with an inlet to the core box to promote smooth fluidized flow through such inlet, the piston moving down with the top level of the sand in the chamber as sand moves through the inlets.

摘要： A method of making sand cores to obtain optimum mechanical properties and particularly to obtain accurate adjustment of the gas curing cycle for making optimum resin-coated sand cores. The method comprises blowing, into a core box cavity, mixture of core making particulated sand and gas curable liquid resin having a first level of pH, such mixture containing a uniform distribution of a pH indicating dye additive that changes color in response to a change in pH level, in contact therewith, such blowing being continued to fill the cavity to a desired density and form an uncured sand core shape with a predetermined porosity, (b) introducing a catalyst gas having a second level of pH, through the pores of the core shape to cure the resin and contact the dye additive, (c) concurrently, or subsequent to step (b), sensing the degree of color change of any part of the core shape that is or has taken place as a result of exposure to the flow front of the catalyst gas, and (d) responding to such color sensing to modify the parameters of catalyst gas introduction (i.e. exposure time, gas pressure, gas concentration or gas inlet/out location) to ensure the desired degree of catalyst reaction in the desired time period.

摘要： A resin coated sand is blown into a core box to form an uncured core with a desired packing density. The core box has one or more inlets to permit ingress of gases and one or more outlets to permit egress of only gases. A non-catalyzing gas is passed through the defined sand core in the core box to create a first effluent and the hydrocarbon content in such first effluent that was exposed to the uncured resin of the sand core is measured. A catalyst carrying gas (nitrogen) is injected into the inlets to pass through the defined sand core within the core box for polymerizing the resin and thence exit from the outlets as a second effluent. The hydrocarbon content of the second effluent is continuously measured (i.e. non-dispersive infrared spectroscopy system). When the hydrocarbon content decreases to approximately the hydrocarbon content of the first effluent, the core box is opened to remove the sand core in a consistently cured condition.
