Publication number: 20140365235Abstract: A personal surgical center embodied as a general purpose computer (e.g. laptop) with wireless technology for monitoring the operation of an independent surgical center and/or handheld instruments. The computer tracks procedures in the operating room and instruments used during those procedures, and accounts for billing, supply management, and payment options. The monitoring of the instruments used during the surgery is conducted by the personal surgical center while actual control of the settings of those instruments is via the independent surgical center or via controls included in the instruments themselves. The monitored information is stored in a log file which is then transmitted to a hospital server for generating reports, inventory control, billing, and the like. Other information generated during the procedure (e.g. doctor notes) is also stored in the log file.Type: ApplicationFiled: April 11, 2014Publication date: December 11, 2014Applicant: DOHENY EYE INSTITUTEInventors: Charles DeBoer, Matthew McCormick, Ralph Kerns, Prashant Bhadri, Lawrence Chong, Mark Humayun

Patent number: 8349196Abstract: A system is provided for etching patterned media disks for hard drive. The modular system may be tailored to perform specific processes sequences so that a patterned media disk is fabricated without removing the disk from vacuum environment. In some sequence the magnetic stack is etched while in other the etch is performed prior to forming the magnetic stack. In a further sequence ion implantation is used without etching steps. For etching a movable non-contact electrode is utilized to perform sputter etch. The cathode moves to near contact distance to, but not contacting, the substrate so as to couple RF energy to the disk. The substrate is held vertically in a carrier and both sides are etched serially. That is, one side is etched in one chamber and then in the next chamber the second side is etched.Type: GrantFiled: December 5, 2008Date of Patent: January 8, 2013Assignee: Intevac, Inc.Inventors: Kevin P.
