  • Publication number: 20060148217
    Abstract: The invention provides a method of forming polycrystalline silicon comprising the steps of: forming a layer of amorphous silicon, forming a layer of metal or metal-containing compound on the layer of amorphous silicon, annealing the layer of amorphous silicon and said layer of metal to form a polycrystalline silicon layer, and irradiating the polycrystalline silicon layer with two different harmonics of a pulsed laser. The pulsed laser is preferably a solid-state laser such as a Nd-Yag laser. One harmonic is chosen such that it is preferentially absorbed by defects in the polycrystalline silicon layer, the other harmonic is absorbed by the bulk polycrystalline silicon.

  • Publication number: 20060103299
    Abstract: Metal induced polycrystallized silicon is used as the anode in a light emitting device, such as an OLED or AMOLED. The polycrystallized silicon is sufficiently non-absorptive, transparent and made sufficiently conductive for this purpose. A thin film transistor can be formed onto the polycrystallized silicon anode, with the silicon anode acting as the drain of the thin film transistor, thereby simplifying production.

  • Publication number: 20060092643
    Abstract: Apparatus for collecting light from an LED and transmitting it in a near-uniform column incudes a conical reflector having a roughed up inner surface about the base of the LED for collecting light emitted to the sides of the LED, and a lens specially designed to focus the collected light into a near-collimated beam. The lens has opposite, substantially elliptical surfaces to collect and collimate the rapidly diverging light from the LED and the reflector, and each lens surface includes a flat spot to prevent shadows from forming, thereby producing a more uniform beam.

  • Patent number: 6973638
    Abstract: A process modeling tool for graphically representing a process which includes transactions and events, and for generating computer code representing the process. A graphical tool creates a graphical representation of the transactions and events with graphical symbols, where one or more of such transactions and events may be of an asynchronous nature. A code generator generates computer code in response to information contained in the graphical representation. The computer code is executable on a computer system to cause the computer system to perform one or more operations which emulate the process shown in the graphical representation.

  • Patent number: 6953716
    Abstract: A metal induced lateral crystallization (MILC) poly-silicon material is produced by depositing a metal in a predefined pattern on amorphous silicon, and heat treating the silicon at a first temperature to form a MILC poly-Si material. The MILC poly-Si material is further heat treated at a second temperature higher than the first temperature to induce recrystallization. The second high temperature recrystallization step significantly enhances the material structure, and in particular the grain structure, of the poly-Si material with substantial benefits to the performance of semiconductor devices made therefrom.

  • Publication number: 20050190788
    Abstract: Systems and methods to implement a shared access gateway are provided that facilitate the multiplexing of multiple enterprise VLAN segments through a single device that translates the VLAN communications from the multiple enterprise segments on the customer side into VLAN communications for delivery over a network service provider network. A single shared access gateway is deployed that is connected to multiple enterprise side network segments. SVLAN controller modules monitor the enterprise side ports of the shared access gateway and processes communications received from those ports. Each SVLAN controller module uses IVL and SVL to maintain its separate forwarding database as packets ingress from the customer side and get processed by the SVLAN controller module. A plurality of translation functions are employed for proper encapsulation of VLAN traffic for transmission over a particular service provider network.

  • Patent number: 6900082
    Abstract: The present invention provides a method for forming metal-induced laterally crystallized polysilicon in which the metal residue is reduced. A first low temperature lateral crystallization is performed using a metal crystallization-inducing agent such as nickel or a nickel compound. A second lateral crystallization is then carried out which may be either a low-temperature crystallization using metal residue from the first crystallization as the metal crystallization-inducing agent, or may be a high temperature crystallization that does not require a metal.

  • Publication number: 20050012585
    Abstract: The present invention provides an inductive element and a method making an inductive element for surface mounting on an adjacent structure that has improved heat transfer characteristics. Specifically, the present invention includes an inductive element where the core and winding define coplanar surfaces that can then be mated to an adjacent structure, preferably a printed circuit board. Devices such as inductors or transformers including the inventive inductive element have multiple, low thermal resistance conductive paths for removing heat from the core and thereby enhance the heat transfer characteristics of the inductive element. The inductive element is particularly well suited for power electronics, such as for use a power choke or as part of a power transformer.

  • Patent number: 6826835
    Abstract: An electric shaver has two elongate shaving heads extending across an upper end of a body on front and rear sides thereof. Each head has co-operable outer cutting foil and inner shearing cutter. A drive mechanism is located in the upper body end and is in drive engagement with the heads for reciprocating the cutters in opposite directions against the corresponding foils for cutting. Each head has a first part and the upper body end includes a second part, which are in movable engagement with each other such that the head is compressible downwardly to move outwardly from the front/rear side of the body, thereby stretching a user's skin flat to facilitate shaving.
