  • Publication number: 20120218186
    Abstract: While 3D visualization is common within numerous other environments (like Movies, Gaming, Traffic reports, Weather reports, etc . . . ) it has only been utilized in the Information Technology (IT) space in so far as displaying virtual rooms or virtual physical environments (i.e. datacenter) and the IT equipment contained in that room. This focus of display may be valuable in some respects; however it is completely different from the concept proposed in this patent. This patent application focuses on a display of the application/service topology in a spatial environment much like a satellite floating in space. The topology is rendered as a collection of configuration items that form a holistic object—regardless of physical location or other physical attributes.

  • Patent number: 8198708
    Abstract: A system and method is disclosed for improving complementary metal oxide semiconductor (CMOS) compatible non volatile memory (NVM) retention reliability in memory cells. A memory cell of the invention comprises a backend layer that reduces charge leakage from a floating gate of the memory cell. A first bottom portion of the backend layer is formed from a first layer of silicon oxynitride having a low value of defect/trap density. A second top portion of the backend layer is formed from a second layer of silicon oxynitride having a high value of defect/trap density. The first layer of silicon oxynitride inhibits electron transport and the second layer of silicon oxynitride protects CMOS devices from plasma induced damage.

  • Patent number: 8114738
    Abstract: A system and method are disclosed for increasing the reliability of a channel erase procedure in an electrically erasable programmable read only memory (EEPROM) memory cell. A memory cell of the present invention comprises a program gate, a control gate, and a floating gate that erase data using a channel erase procedure. An erase capacitor is coupled to the floating gate to provide a low voltage bias that decreases the voltage that is required to perform a Fowler-Nordheim erase process in the memory cell. The erase capacitor of the present invention is formed without adding a step in the manufacturing process of the memory cell. Memory cells of the present invention are low cost, high endurance, low voltage memory cells.

  • Publication number: 20110041242
    Abstract: A water saving toilet flush system to selectively practice a partial or a full flush at the selection of the user is disclosed. A partial flush operation is initiated by depressing the control handle to commence the flush to connect a magnet assembly and to simultaneously unseat an associated flapper valve. Then the control lever is lifted to uncouple the magnet assembly and allow a float assembly to control seating of the flapper valve. A full flush operation is initiated in the same manner the partial flush operation is initiated. However, the control lever is allowed to remain depressed, causing the magnet assembly to remain coupled until a water level is low enough to cause the flapper valve to uncouple the magnet assembly and to drop to a closed position completing the full flush cycle.

  • Patent number: 7804714
    Abstract: A system and method are disclosed for providing an electrically programmable read only memory (EPROM) in which each memory cell comprises an NMOS select transistor with a thick gate oxide and a PMOS breakdown transistor with a thin gate oxide. The source of the NMOS transistor and the source, drain and N well of the PMOS transistor are connected. The gate of the PMOS transistor is grounded. Under the control of the NMOS transistor, a programming voltage pulse is passed to the N well of the PMOS transistor of a selected memory cell. The magnitude of the voltage is sufficient to break the thin gate oxide of the PMOS transistor without damaging the NMOS transistor. Because the memory state of the memory cell depends on the breakdown status of the PMOS transistor, the data may be retained in the memory cell for an unlimited period of time.

  • Patent number: 7586792
    Abstract: A system and method are disclosed for providing drain avalanche hot carrier (DAHC) programming for non-volatile memory (NVM) applications. A memory cell of the present invention comprises a program transistor and a control capacitor, each having a gate coupled together to form a floating gate. The size of the program transistor is selected to create a coupling ratio between the program transistor and the control capacitor that is large enough to facilitate a Fowler-Nordheim erase process and small enough to facilitate DACH programming. A source bias voltage is supplied to the source of the program transistor to increase the hot electron injection rate and to decrease the hot electron generation rate in the memory cell.

  • Patent number: 7447064
    Abstract: A system and method is disclosed for providing a CMOS compatible single poly electrically erasable programmable read only memory (EEPROM) with memory cells that comprise an NMOS program transistor. In a first embodiment the memory cells of the EEPROM comprise a PMOS control capacitor. In a second embodiment the memory cells of the EEPROM comprise an NMOS control capacitor. A well bias voltage is applied to the NMOS program transistor instead of a gate bias voltage. The well bias voltage enables the injection of (1) channel hot electrons, (2) second hot electrons initiated by the channel hot electrons, and (3) drain impact ionization hot electrons into a floating gate of the NMOS program transistor.

  • Patent number: 5490590
    Abstract: The present invention provides a chain wear monitoring device for monitoring chain wear in a chain drive conveyor system. The chain wear monitor electronically measures, calculates, records, and reports the amount of chain wear along the entire length of the conveyor chain. The monitor calculates the wear as the number of inches per nominal ten foot section of chain. A large diameter measuring wheel is rotatably mounted on a shaft extending from the monitor control box. An encoder connected to the wheel is used measure the distance of the chain and a proximity sensor counts the links. A magnetic assembly may be fixed to the chain to cause the monitor to automatically start and stop a data recording session for a chain on a conveyor system at the same spot each time the chain is monitored, facilitating section by section comparison of chain wear.
