摘要:
Using a document scanner or other image input device of an image or document processing system to periodically scan or image printed test images from a plurality of marking engines replaces internal sensors as a feedback means in image quality control. For example, image lightness (L*) is controlled by periodically printing mid-tone test patches, scanning the printed test patches with a main job document scanner and analyzing the scanned image to determine updated marking engine actuator set points. For instance, ROS exposure and/or scorotron grid voltages are adjusted to maintain image lightness consistency between marking engines.

An image rendering system periodically prints test patches on a duplex sheet from a plurality of marking engines, using a simple emitter-detector pair as a feedback means in image quality control. Image lightness is controlled by analyzing the test patches to determine updated marking engine actuator set points. For instance, ROS exposure and/or scorotron grid voltages are adjusted to maintain image lightness consistency between marking engines.
摘要:
A golf club head, particularly for putting, includes a main body having a leading section and a trailing section where the leading section has a top edge and a bottom edge and the trailing section has a top edge and a bottom edge. A sole portion interconnects the bottom edge of the leading section and the bottom edge of the trailing section. A heel portion and a toe portion each include a weight disposed therein. In addition, a third weight is disposed in the trailing section of the club. The weighting is such that the moment of inertia of the club head is increased over known putters.
