Title: Oil well tubing injection system
Inventor: GIPSON TOMMIE C
IPC: E21B19/22
Filed: 2002-04-29
Granted: 2007-04-17
Abstract: The injector of the invention provides a means and method for injecting either coiled tubing or conventional stalked tubing into and from a well by developing axial forces in the tubing. The curvature of the coiled tubing is simultaneously selectably alters on the opposite side of the injector from the wellhead. To develop traction on the tubing, the injector relies upon an array of opposed pairs of annularly grooved driven rollers which are urged into contact with the tubing. The pairs of rollers are mounted in an alternating pattern 90° apart so that the tubing is well supported and urged into roundness. Integral with the injector, but deactivated when the injector is used with stalked tubing, is a selectably operable tubing straightener which serves to straighten the tubing before entry into the well and also to recurve the tubing being withdrawn from the well to control its arcuate path between the injector and the tubing storage reel. Additionally, the injector unit has an integral slip unit for gripping the tubing in cases when it is desirable to support the tubing axially without operating the tractive portion of the injector.

Abstract: An object of the present invention is to enable the detection of a mixture ratio indicating the mixture state of a plurality of objects, such as a background image and a moving object image. A normal-equation adder 541 extracts mixed pixel data according to a motion, and also extracts background pixel data corresponding to the mixed pixel data so as to generate relational expressions for a designated pixel. A normal-equation calculator 542 detects the mixture ratio indicating the mixture state of the objects based on the relational expressions. The normal-equation adder 541 generates the plurality of relational expressions based on a first approximation in which foreground object components change substantially linearly, and a second approximation in which the mixture ratio changes substantially linearly. The present invention is applicable to a signal processing apparatus for processing images.
