  • Publication number: 20130035392
    Abstract: It pertains to selective inhibition of C3 convertase of the alternative pathway of complement as well as the previously claimed assembly of the membrane attack complex of complement by use of less than 1 kDa molecular weight forms of the aurin tricarboxylic acid synthetic complex (ATAC), and their derivatives. It further pertains to the use of these materials to treat human conditions where there is evidence of self destruction of host tissue by C3 convertase activation of the alternative complement pathway, or the membrane attack complex, or both pathways. These diseases include, but are not limited to, paroxysmal nocturnal hemoglobinemia, rheumatoid arthritis, multiple sclerosis, malaria infection, Alzheimer disease, age related macular degeneration, and atherosclerosis.

  • Publication number: 20130002152
    Abstract: A lamp tube switching circuit includes a first connector and a second connector for connecting either an LED lamp tube or a fluorescent type lamp tube, a switch module being a mechanical switch including first, second and third switches, a starter and ballast. Each of the first and second switches has a static terminal for connecting with a power supply, and four dynamic terminals for selectively connecting with the static terminal thereof. Different circuits can be configured by adjusting the connection between the static and dynamic terminals, wherein each circuit can drive a selected type of lamp tube to generate light.

  • Publication number: 20020000605
    Abstract: A method of fabricating a flash memory device including an array of split gate cells, comprising the steps of: providing a silicon substrate having a top surface; implanting ions into a predefined area of the substrate to form a common source region of the substrate; forming at least one floating gate over the substrate, each floating gate being associated with one of the cells and having a portion which overlies a portion of the common source region, the overlying portion of each floating gate providing for a high coupling ratio for the associated flash cell; forming a select gate over at least a portion of each floating gate; and forming a drain region associated with each cell. The high coupling ratio flash cell device of the present invention overcomes limitations associated with conventionally formed split gate flash cells by forming the common source region first and then forming the floating gates over the common source region in order to provide a high coupling ratio for the cells.

  • Patent number: 6301151
    Abstract: Adaptive programming method and apparatus for flash memory analog storage. The present invention method is to adjust the voltage of the programming pulse each time based on the result of the previous pulse. The expected change in the programmed value is compared to the measured change, and the difference used to improve the model of that cell after each programming pulse. The algorithm is “adaptive” because the voltage of each pulse is adapted to whatever the cell needs. If the cell is programming too slowly, the voltage is increased dramatically to make it faster. Conversely if the results show that a particular cell is programming too fast, the next voltage pulse is increased by only a small amount (or even decreased if necessary). Because the response of the cell is non-linear, a special analog circuit is used to calculate the optimum voltage for each pulse. As one alternative, a digital calculation may also be used to program the cells.
