Granted: 1997-05-27
Abstract: A sheet of writing paper which is white, but which has been colored, or tinted to a pastel color by printing on its surface with a strippable or chemically removable ink. The surface printing with ink allows the paper to have a desirable tinted color, but allows the color to be easily removed so that the paper can be relatively easily recycled and reused without the normal problems associated with recycling of vat-dyed tinted papers. The surface printing can be accomplished by printing a random spotted pattern on the paper to provide for the perception of tinting. The invention allows the printed pattern to have a random-toned effect or allows the visual incorporation of words or symbols which would very subtly appear, macroscopically, in the tinting pattern.

Patent CA-2124603-C (CA)
Inventor: STONE MAUREEN C
IPC: G06T11/00
Filed: 1994-05-30
Granted: 1999-02-23
Abstract: A method for operating a processor-controlled machine, and a machine having a processor, are disclosed for producing human perceptible output related to an image display feature presented in an original image using the model data structure (the model) from which the original image was produced. In response to the display of an output producing region displayed coextensively with a first image segment including a display feature representing a data item in the model, some form of human perceptible output is produced using the data item and presented by an output utilization device at the same time as the first image is being displayed, giving the perception to a machine user of providing information related to the display feature in the first image segment. In one aspect of the invention, the human perceptible output is a second image displayed in the spatial context of the first image defined by the output producing region, called a viewing operation region, or VOR. The VOR functions as a type of "visual filter", binding the second view of a original image to the display area defined by the VOR. One type of second image produced shows the display feature in the first image modified in the second image. The second image is produced using a new attribute value for the data item in the model represented by the image display feature in the image, producing a modified display feature that is then presented in the VOR in the spatial context of the first image, simultaneously with the display of the first image and replacing the first image segment. In one illustrated embodiment, the method operates within the environment of a rendering application executing in a graphical user interface environment. A machine user moves the VOR over a portion of a rendered image, and in response to the user's movement action, a viewing operation associated with the VOR invokes the renderer that produced the original rendered image to produce a second modified view of the original image using a new value for a global parameter data item in the scene description. The second image is then clipped to the size and shape of the VOR, and is then presented in the VOR, showing the second modified view.

Granted: 2000-02-01
Abstract: A method and apparatus for selecting gear shift points is disclosed wherein vehicle speed and grade are monitored by sensors which provide data which is used to calculate vehicle acceleration adjusted to compensate for the effect of vehicle grade. A gross vehicle weight value is determined from the adjusted acceleration value. Based on the determined gross vehicle weight and the existing grade, the horse power required to sustain the current GVW and grade with zero acceleration is calculated.      Also the current GVW and grade are used to determine the rate of vehicle speed loss during the torque interrupt period in order to predict the engine speed in the new gear and calculate the horse power available from the engine at shift completion. If the predicted engine speed is above a predetermined minimum and if the horse power available from the engine at completion of the shift is equal to or greater than the horse power required to maintain the current vehicle speed, the shift is permitted, otherwise the shift is not permitted and the measurements end calculations necessary to make the shift point decision are repeated. The minimum predicted engine speed may be adjusted to reflect driver demand as represented by throttle position.

Abstract: A fluid injector assembly for drawing a first fluid into the flow of a second fluid. The injector assembly includes an eductor including an inlet having a plurality of openings, a first outlet port, and a first fluid passage extending between the inlet and the first outlet port. The openings are generally disposed tangentially to the first fluid passage. The inlet is adapted o be placed in fluid communication with the second fluid such that the second fluid flows through the first fluid passage from the inlet to the first outlet port. The fluid injector assembly also includes a throat having an inlet port, a second outlet port and a second fluid passage extending between the inlet port and the second outlet port. The inlet port of the throat is spaced apart from the first outlet port of the eductor forming a gap therebetween. The gap is adapted to be placed in fluid communication with the first fluid. As the second fluid flows through the first passage, the tangential openings of the eductor cause the second fluid to swirl as the second fluid flows through the first fluid passage and to form a vortex n the gap as the second fluid flows out of the first outlet port. The vortex of the second fluid creates a low pressure zone within the gap which draws the first fluid into the gap wherein he first fluid and the second fluid enter the inlet port of the throat and flow through the second fluid passage.
