  • Publication number: 20060226498
    Abstract: A power transistor includes a plurality of transistor cells. Each transistor cell has a first electrode coupled to a first electrode interconnection region overlying a first major surface, a control electrode coupled to a control electrode interconnection region overlying the first major surface, and a second electrode coupled to a second electrode interconnection region overlying a second major surface. Each transistor cell has an approximately constant doping concentration in the channel region. A dielectric platform is used as an edge termination of an epitaxial layer to maintain substantially planar equipotential lines therein. The power transistor finds particular utility in radio frequency applications operating at a frequency greater than 500 megahertz and dissipating more than 5 watts of power. The semiconductor die and package are designed so that the power transistor can efficiently operate under such severe conditions.

  • Patent number: 7008948
    Abstract: This invention describes novel pyrazole compounds of formula IV: wherein Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; Rx and Ry are independently selected from T-R3, or taken together with their intervening atoms to form a fused, unsaturated or partially unsaturated, 5-8 membered ring having 1-3 ring heteroatoms selected from oxygen, sulfur, or nitrogen; and R2, R2?, T, and R3 are as described in the specification. The compounds are useful as protein kinase inhibitors, especially as inhibitors of aurora-2 and GSK-3, for treating diseases such as cancer, diabetes and Alzheimer's disease.

  • Publication number: 20060029924
    Abstract: Disclosed is an assay device comprising liquid transport means adapted to take up a liquid sample and conduct the liquid to an analyte detection region operable to provide a test signal indicative of the presence and/or amount of an analyte in the liquid sample; the assay device further comprising a sample presence signal generation means, which is not generated by means of an immunoreaction. This sample presence signal generation means can comprise a coloured portion, which is overlaid by a material (e.g. nitrocellulose) that is opaque, when dry, and translucent or transparent, when wet, to allow the coloured portion to become visible to the user. In another embodiment the signal generation means comprises a colour changing material which under-goes a change in its visible properties upon wetting (eg. pH indication). A third embodiment uses a mobilisable detectable which, when wetted by the sample, is carried along resulting in a streaked line parallel with the flow direction.

    Abstract: An integrated circuit (10) includes a semiconductor substrate (11) that has a top surface (32) for forming a dielectric region (14) with a trench (40) and one or more adjacent cavities (16). A conductive material such as copper is disposed within the trench to produce an inductor (50). A top surface (49) of the inductor is substantially coplanar with an interconnect surface (31) of the semiconductor substrate, which facilitates connecting to the inductor with standard integrated circuit metallization (57).

  • Publication number: 20050191978
    Abstract: An antenna diversity receiver comprises a zero-IF receiver connected to two antennas (102a, 102b) via switches (532, 534). Simultaneous measurement of signal qualities from both antennas is possible by routing signals from the first antenna (102a) via a first mixer (106) and channel filter (116) and routing signals from the second antenna (102b) via a second mixer (108) and channel filter (118). A diversity controller (536) compares the signal qualities received from the antennas (102a, 102b) during a data preamble to select a preferred antenna, then adjusts the switches (532, 534) to route the signals from the preferred antenna to both input mixers (106, 108). The amplifier (104a, 104b) connected to the deselected antenna may be switched off during data reception, thereby minimising extra power consumption. Such an antenna diversity receiver enables effective antenna selection to be performed, even in systems such as Bluetooth where only a very short preamble is provided for receiver configuration.

  • Publication number: 20050133672
    Abstract: An aircraft comprises a wing tip device, for example a winglet, a raked-tip device, a wing tip fence or a planar wing extension, mounted in the region of the tip of a wing on the aircraft. The wing tip device is rotatably moveable between a first position and a second position, in which the upward lift produced by the wing or the wing tip device is reduced. During flight, the bending moment at the root of the aircraft wing therefore changes in dependence on the position of the wing tip device. The maximum bending moment in the aircraft wing sustained during high-load conditions is thereby reduced, allowing the structural mass of the aircraft to be reduced.
