Patent number: 8088267Abstract: Controlled electrokinetic transport of constituents of liquid media can be achieved by connecting at least two volumes containing liquid media with at least one dielectric medium with opposing dielectric surfaces in direct contact with said liquid media, and establishing at least one conduit across said dielectric medium, with a conduit inner surface surrounding a conduit volume and at least a first opening and a second opening opposite to the first opening. The conduit is arranged to connect two volumes containing liquid media and includes a set of at least three electrodes positioned in proximity of the inner conduit surface. A power supply is arranged to deliver energy to the electrodes such that time-varying potentials inside the conduit volume are established, where the superposition of said potentials represents at least one controllable traveling potential well that can travel between the opposing conduit openings.Type: GrantFiled: April 2, 2008Date of Patent: January 3, 2012Assignee: Tesla LaboratoriesInventors: Patrick Ismail James, George Stejic

Patent number: 6101971Abstract: Apparatus and method for implanting ions into a workpiece surface. A concentration of ions is produced. An optical analysis of the concentration of ions is performed and recorded. The constituency of the ion concentration is determined by comparing the optical analysis data with a database of records on a storage medium wherein the optical analysis data for given concentrations of ions have been stored for subsequent access. Ions from the ion concentration are caused to impact a workpiece surface. The dose of ions implanted into the workpiece is measured. Implantation of the workpiece is stopped once an appropriate dose has been reached.Type: GrantFiled: December 22, 1998Date of Patent: August 15, 2000Assignee: Axcelis Technologies, Inc.Inventors: A.
