摘要： A sheet formation section of a paper machine includes a sensor that measures a first characteristic of a sheet of paper being formed. The sensor may measure a characteristic such as streaking, rises, depressions, or smoothness. The sheet formation section also includes an apparatus that applies a magnetic field to the sheet of paper being formed. The machine also includes a controller that causes the apparatus to apply the magnetic field in response to a signal from the sensor representative of the first characteristic. The magnetic field transforms a second characteristic of the sheet of paper. The apparatus may transform a characteristic such as water content or fiber orientation.

摘要： Methods for measuring tissue defects include the use of a suture anchor, a drill guide, a needle driver, and a ruler. Using the drill guide, the surgeon extends the suture attached to an implanted anchor between the first and second ends of the defect. The surgeon then attaches a needle driver to the suture extending from the proximal end of the drill guide. Finally, the surgeon retracts the suture back through the drill guide and measures the distance between the needle driver and the proximal end of the drill guide to determine a length of a graft needed to repair the defect.
