Abstract: A system and method for maintain a desired degree of platen flatness is disclosed. A laser system is used to measure the flatness of a platen. The temperature of the platen is then varied to achieve the desired level of flatness. In some embodiments, this laser system is only used during a set up period and the resulting desired temperature is then used during normal operation. In other embodiments, a laser system is used to measure the flatness of the platen, even while the workpiece is being processed.

Abstract: A transforaminal lumbar interbody fusion (TLIF) implant to be placed in an intervertebral space includes a front member and a back member. The front member includes a first end having a hinge, a second end, a pair of lateral portions, a top wall and a bottom wall, an opening configured through the pair of lateral portions and a plurality of openings in each of the top wall and the bottom wall. The back member includes a first end having an arcuately-shaped attachment head comprising a receptor dimensioned and configured to accommodate the hinge of the front member, a second end, a pair of lateral portions, a top wall, a bottom wall and an opening configured through the pair of lateral portions. The top wall and the bottom wall of the back member further comprise a plurality of openings.

Abstract: A beam line ion implanter includes an ion source configured to generate an ion beam, a scanner configured to scan the ion beam to produce a scanned ion beam having trajectories which diverge from a scan origin, and a focusing element having a focusing field positioned upstream of the scanner configured to focus the ion beam to a focal point at the scan origin. A method of ion beam tuning includes generating an ion beam, focusing the ion beam to a focal point positioned at a scan origin, and scanning the ion beam to produce a scanned ion beam having trajectories which diverge from the scan origin.
