Patent CA-2124603-A1 (CA)
Inventor: STONE MAUREEN C
IPC: G06T11/00
Filed: 1994-05-30
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.

Title: Automotive floor liner
Inventor: NIEMI KARL A
IPC: B60N3/04
Filed: 1994-08-15
Abstract: Protection for the rear carpet areas of an automobile such as a sport utility vehicle is provided by a unitary sheet of heavy-gauge extruded, high-density polyethylene. The floor liner has a floor panel which covers the floor of the cargo area of a sports utility vehicle. The floor panel has sides which extend along and are tucked under the wheel well trim panels on either side of the cargo area. Integrally formed with, and attached to, the forward edge of the floor panel, are two cargo extension panels. The cargo extension panels form a continuation of the forward edge of the cargo floor panel and are separated from each other by a seat back accommodation slot. This slot divides the cargo extension panels so that each panel corresponds to the width of the seat back positioned forward of each panel. Continuing on from the cargo extension panels are recumbent panels which are integrally formed with and joined to the cargo panels. These in turn are joined to integrally formed seat back panels. The joints between the panels are of the type known as a "living hinge" and are cold-formed into the material of the liner itself. The double living hinges provide resilient, long-life hinges impervious to liquids and provide flat extended edges of unproved appearance and safety. The spring-loaded extension panel of a vehicle urges the seat back panel against a seat back and hence retains the liner without additional fasteners.
