  • Patent number: 8243358
    Abstract: We present an invention on the synthesis of elastic, bio-compatible functional microstructures wherein the designed electrical functionalities are achieved by mixing conducting nano to micro-particles with PDMS gels. The methodology for constructing planar and three-dimensional microstructures by soft-lithographic technique is presented. Applications such as electrodes, conducting strips, two and three-dimensional microstructures for electrical wiring connections, micro heaters, micro heater arrays, flexible thermochromic displays, and applications for microfluidic devices are demonstrated, all with demonstrated elastic flexibility and fall-proof characteristics while maintaining their functionalities. Results obtained are very promising for the utilization of such composites in future micro-fabrications, especially for the bio-chips and microfluidic devices.

  • Patent number: 8143465
    Abstract: The present invention relates to a novel process of preparing branched polymers by cyclotrimerization and branched organic materials containing triaroylbenzene moieties as base structural unit. The polymerization is a simple one-pot reaction, strictly regioselective and highly functionality-tolerant giving oligomeric and polymeric polymers with high degree of branching (up to 100%) in high yields (up to 99%). The polymers are processible, easily film-forming, transformable (curable) into thermosets by heat or irradiation, and readily crosslinkable by UV irradiation to give patterns with nanometer resolution. The polymers of the present invention can be blend with a variety of macromolecules for general use. The polymers can be metallified utilizing organometallic acetylene as building blocks and ceramization of the patterns of the obtained polymers afford ferromagnetic ceramic patterns with high resolution.

  • Publication number: 20090032820
    Abstract: A field-effect transistor includes a first gate, a second gate held at a substantially fixed potential in a cascode configuration, and a semiconductor channel. The semiconductor channel has an enhancement mode portion and a depletion mode portion. The enhancement mode portion is gated to be turned on and off by the first gate, and has been modified to operate in enhancement mode. The depletion mode portion is gated by the second gate, and has been modified to operate in depletion mode and that is operative to shield the first gate from voltage stress.

  • Patent number: 7374763
    Abstract: Protein sequences encoding antigenized antibodies for treatment of foot-and-mouth disease (FMD) or foot-and-mouth disease virus (FMDV) of swine is provided. The antigenized antibodies are created from the grafting of peptide epitopes derived from FMDV into swine antibody CDR loops. FMDV peptide epitopes are cloned by PCR from VP1 gene of FMDV. The overlapping PCR method is used to insert the FMDV peptide epitopes into the CDR regions of swine immnuoglobulin heavy and light chains genes. The resulting antigenized antibody genes were cloned into mammalian expression vector. The plasmids are transfected into CHO or myeloma cells. The stable transfectant cell line was selected for high yield of the desired protein antibodies.

  • Patent number: 7135355
    Abstract: A method for the fine-pitch stencil mask design for stencil printing bumping technology for eutectic Sn/Pb and lead-free solder material is described. In the method, a reflowing enhancement layer is introduced to improve the solder quality and reduce the pitch of solder bumps. The method of forming the layer is described as well as the forming method of matching under-bump metallurgy layer. The method of stencil mask design can match various sizes and pitch of the solder bumps. The designed mask is fixed on the stencil printer to deposit the solder materials with the required patterns. This method can increase the solder paste volume to increase the height of solder bumps after the reflowing process.

  • 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: 20050024307
    Abstract: This invention provides a method and apparatus for driving bistable cholesteric liquid crystal displays. The method and apparatus provided a display in which all the pixels are initially driven to the P state. Selected pixels for the display are then driven to the FC state to provide the desired message. The state of the pixels is then maintained for a viewing period prior to any resetting of the display to the P state. The switching from the P state to the FC state allows faster addressing times and lower voltages to be used in driving the display.

  • Patent number: 6576333
    Abstract: This invention provides a composite material having a matrix of structural material containing embedded zones of soft elastic material and zones of solid relatively high density material within the soft elastic material. By selecting a particular resonance frequency for the subunits of soft elastic material and solid high density material, frequencies just lower than the resonance frequencies will be unable to propagate through the material and be strongly reflected or absorbed. Such material may be used in the manufacture of filters or shields against particular target frequencies. Subunits having a variety of resonance frequencies may provide a broader range of frequencies that the material may shield.
