| Number | Title | Issue Date |
| 7172550 | Adjustable coupling mechanism for the conduit on a ventricular assist device A conduit assembly for attachment to a mechanical circulatory device, such as a VAD, and a method of using the same. The conduit assembly includes a conduit having a first rigid, curved conduit and a second rigid, curved conduit. A first coupling attaches a first en... | 02/06/2007 |
| 5831373 | Cathode ray tube with plural electron gun assemblies A cathode ray tube includes a vacuum envelope having a face plate (1), a continuous phosphor screen (7) formed on the inner surface of the face plate (1), the phosphor screen (7) including a plurality of scanning regions (R1-R15) disposed in rows and colu... | 11/03/1998 |
| 5712537 | High frequency scan converter By using a sheet beam and a charge-storing target measuring the differential of the deposited charge, one can greatly improve the performance of a scan converter. A segmented target provides instantaneous analog output.... | 01/27/1998 |
| 4471270 | Particle-impact localizing device, a cathode-ray oscilloscope and a pick-up tube comprising such a device This device comprises several charge-transfer shift registers integrated on the same semiconductor substrate and disposed one above the other along the axis Oy. The charge-transfer electrodes are common to all the registers and each package of charges inj... | 09/11/1984 |
| 4423354 | Method and apparatus for controlling electrode voltage in electron beam tubes A controlling electrode is positioned in physical proximity to one or more electrodes in an electron beam tube so that the controlling and controlled electrodes are subject to common electron bombardment. A control voltage of preselected magnitude and pol... | 12/27/1983 |
| 4361783 | Target for picture tube, tube provided with such a target and picture apparatus incorporating such a tube The invention relates to a shooting target. The signal plate covering one of the faces of the actual target is subdivided into a plurality of electrically independent elementary signal plates in order to reduce the stray capacitance during the sampling of the ... | 11/30/1982 |
| 4013968 | Feedback controlled storage tube devices The combination of a storage tube and a feedback circuit operatively intercoupled such that as data is read from the storage tube the level of stored charge on each incremental area of the dielectric of the tube's target is sensed and the potential betwee... | 03/22/1977 |
| 4005408 | Multiple electron beam analog to digital converter A typical embodiment of the invention is a multiple electron beam device converting analog input signals into coded digital output signals. A beam of electrons, generated through a Watkins-Johnson laminar flow sheet beam electron gun is focused before b... | 01/25/1977 |
