Patent number: 7644680Abstract: A method and electrode assembly for treating a substrate with a non-equilibrium plasma in which the electrode assembly has two or more spaced barrier electrodes and a ground electrode spaced apart from the two spaced barrier electrodes for passage of a substrate to be treated. Plasma fluid medium is introduced between the barrier electrodes and is biased to provide a greater flow to an inlet region of the electrode assembly to help inhibit the ingress of air. Each of the barrier electrodes can be provided with central and leg sections having passages for introducing a cooling fluid into one of the leg sections and discharging said cooling fluid from the other of the leg sections. The central section can be provided with a transverse cross-sectional area less than that of the leg sections to increase velocity in the central section.Type: GrantFiled: February 15, 2007Date of Patent: January 12, 2010Assignee: Praxair Technology, Inc.Inventor: Yeu-Chuan Simon Ho

Patent number: 5757365Abstract: A computer system includes a CPU and VGA/LCD controller interacting with a main system memory for processing input data and displaying it on an LCD panel screen that includes a plurality of row and column drive chips on the panel. Each column drive chip includes a panel driver memory and panel driver control logic. A frame rate modulated grey-scale data signal is fed from the processor and VGA/LCD controller to the panel driver memory. Timing signals, including horizontal and vertical clocks, and data shift signals, are fed to the panel driver control circuit to control the panel driver memory from which data is read out for display on the LCD panel screen. Upon detection of the absence of screen update information for two full frame periods the system enters a power down mode by re-mapping the grey-scale data to black-and-white data, stopping the data shift clock, and disabling portions of the VGA/LCD controller and its sequencer so that the latter enters a screen off mode.Type: GrantFiled: June 7, 1995Date of Patent: May 26, 1998Assignee: Seiko Epson CorporationInventor: Simon Ho
