Quotables
"To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth--all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances."
Lee deForest, American radio pioneer ; 1957

| Number | Title | Issue Date |
| 7143414 | Method and apparatus for locking multiple semaphores Processor threads in a multi-processor system can concurrently lock multiple semaphores by providing a lock command which includes the semaphore value and a semaphore number. Each processor is allocated two or more addressable semaphore stores, each of which include... | 11/28/2006 |
| 7103805 | Bus monitor unit A central node for a data bus system includes a bus monitor unit with receiver means for registering signals on the data bus, and evaluation means which detect incorrect communication on the data bus and at least temporarily block communication by the user that caus... | 09/05/2006 |
| 7089555 | Ordered semaphore management subsystem An ordered semaphore management subsystem and method for use in an application system which includes a plurality of processors competing for shared resources each of which is controlled by a unique semaphore. The subsystem generates an ordered semaphore field (OSF) ... | 08/08/2006 |
| 6978374 | Authorization key system for selectively controlling the performance of a data processing system The present invention provides methods and apparatus for authorizing a temporary or permanent increase in the performance of a data processing system while providing little or no down time. This is accomplished by including extra or additional computer resources in ... | 12/20/2005 |
| 5537007 | Field emitter display device with two-pole circuits By incorporating two-pole circuits (13) as switching elements in a picture display device based on field emission, the emission (and hence the picture intensity) is substantially defined by the charge of a capacitance (15) associated with a part of a pixe... | 07/16/1996 |
| 5489771 | LED light standard for photo- and videomicroscopy The invention relates to a light calibration system consisting of a compact LED source with feedback control of intensity. The source is positioned in the focal plane of the microscope objective and produces flat-field illumination of up to 31 microwatts.... | 02/06/1996 |
| 5399910 | High voltage/current pulse generator using spark gaps A high voltage/high current electric pulse generator. Spark gap switches (E1, E2, E3) having a trigger electrode are connected to a trigger control circuit (CD). Switch (E1) is connected between the outer conductor of cable (C2) and an inner conductor of ... | 03/21/1995 |
| 5179327 | High tension cable device A high tension cable device according to the present invention for use with an ignition system having a discharge tube for forming a series gap therein in an automobile engine or the like can eliminate a so-called creeping discharge which is likely to occ... | 01/12/1993 |
| 4508993 | Fluorescent lamp without ballast It is known that electrical discharges in capillary tubing shows a positive volt-ampere characteristic even for low pressure gas fills. In contrast, conventional fluorescent lamps exhibit a negative volt-ampere characteristic and, accordingly, require spe... | 04/02/1985 |
| 4367432 | Blended lamp In a blended lamp, an incandescent filament and a high-pressure discharge tube are arranged electrically in series. The filament forms part of a halogen incandescent lamp and the discharge tube contains a sodium amalgam which is very high in mercury. A re... | 01/04/1983 |
