Abstract: A printing system includes a media transport system and first and second printheads that print first and second patterns on first and second sides of the media, respectively. An image registration system includes a fiducial including an origin and first and second sides. A first camera captures a first fiducial image of the first side and origin and a first pattern image of the first pattern. A second camera captures a second fiducial image of the second side and origin and a second pattern image of the second pattern. A registration controller processes the first and second fiducial images and pattern images to determine a relative position of the first and second patterns. A print controller, controlling printhead operation, adjusts the registration of subsequently printed patterns on at least one of the first and second sides of the media based on the determined relative pattern position.

Abstract: A method of printing includes printing first and second patterns at first and second locations on first and second sides of a media using first and second printheads, respectively. First and second fiducial images including a fiducial origin are captured using first and second cameras, respectively. First and second pattern images of the first and second patterns are captured using the first and second cameras, respectively. The locations of the first and second patterns relative to the fiducial origin are determined using an image registration controller. A relative printed location of the first pattern and the second pattern is determined. A deviation is determined by comparing the determined relative location of the first and second printed patterns with an intended relative location of the first and second printed patterns.

Abstract: A method of assaying work of an earth boring bit of a given size and design comprises the steps of drilling a hole with the bit from an initial point to a terminal point. A plurality of electrical incremental actual force signals are generated, each corresponding to a force of the bit over a respective increment of the distance between the initial and terminal points. A plurality of electrical incremental distance signals are also generated, each corresponding to the length of the increment for a respective one of the incremental actual force signals. The incremental actual force signals and the incremental distance signals are processed to produce a value corresponding to the total work done by the bit in drilling from the initial point to the terminal point. Using such a basic work assay, a number of other downhole occurrences and/or conditions can be assayed.
