  • Patent number: 8857185
    Abstract: An example power generation system includes a vapor generator, a turbine, a separator and a pump. In the separator, the multiple components of the working fluid are separated from each other and sent to separate condensers. Each of the separate condensers is configured for condensing a single component of the working fluid. Once each of the components condense back into a liquid form they are recombined and exhausted to a pump that in turn drives the working fluid back to the vapor generator.

  • Publication number: 20130174552
    Abstract: A power generation system includes a non-azeotropic working fluid mixture and a Rankine cycle system. The Rankine cycle system includes a turbine generator that is driven by vapor of the first working fluid mixture, and a condenser that exchanges thermal energy between the vapor received from the turbine generator and a cooling medium. The working fluid mixture is characterized by a condenser temperature glide during phase change between approximately five degrees and thirty degrees Kelvin, a condensing pressure between approximately one tenth of one percent and eleven percent of a critical pressure of the working fluid mixture, and a condenser bubble point temperature between approximately one degree and nine degrees Kelvin greater than a temperature at which the cooling medium is received by the condenser.

  • Patent number: 8410584
    Abstract: Described herein are semiconductor device packages with EMI shielding and related methods. In one embodiment, a semiconductor device package includes: (1) a substrate unit including a grounding element disposed adjacent to a periphery of the substrate unit and at least partially extending between an upper surface and a lower surface of the substrate unit; (2) a semiconductor device disposed adjacent to the upper surface of the substrate unit; (3) a package body disposed adjacent to the upper surface of the substrate unit and covering the semiconductor device; and (4) an EMI shield disposed adjacent to exterior surfaces of the package body. A periphery of the package body is laterally recessed, such that a connection surface of the grounding element is electrically exposed and electrically connected to the EMI shield. The grounding element provides an electrical pathway to ground electromagnetic emissions incident upon the EMI shield.

  • Publication number: 20120259099
    Abstract: The present invention relates to a method for manufacturing multimers by making repeat chains comprising repeatedly linked affinity domains binding specifically to monomers, and by using the same to create a repeat chain/multiple-monomer complex created from the repeat chains and multiple number of monomers, thereby facilitating the formation of bond bridges between the monomers in the complex to produce inter-monomeric bond bridged multimer. The present invention relates to a method for manufacturing multimers by making repeat chain recombinant proteins resulting from the repeated linking affinity domain proteins binding specifically to protein monomers, and by using the same to create a repeat chain/multiple-monomer complex created from the repeat chains and multiple number of monomers, thereby facilitating the formation of bond bridges between the monomers in the complex to produce inter-monomeric bond bridged multimer.

  • Publication number: 20120006511
    Abstract: A heat exchanger includes a plurality of channels and one or more active flow disruption members disposed at an entrance to the plurality of channels. The active flow disruption members are configured to induce unsteadiness in a flow through the plurality of channels to increase thermal energy transfer in the plurality of channels. A method for transferring thermal energy from a heat exchanger includes locating one or more active flow disruption members at an entrance to a plurality of channels of the heat exchanger. A flow is directed across the one or more active flow disruption members into the plurality of channels and an unsteadiness is produced in the flow via the one or more active flow disruption members. The unsteadiness in the flow increases the transfer of thermal energy between the heat exchanger and the flow.

  • Publication number: 20080137909
    Abstract: A gaze position tracking method and apparatus for simply mapping one's gaze position on a monitor screen are provided. The gaze position tracking apparatus includes an image capturing module, and an image processing module. The image capturing module illuminates infrared rays to a user's eyes, reflects an illuminated eye image at 45°, and captures the 45° reflected eye image. The image processing module obtains a pupil center point of the illuminated eye image by performing a predetermined algorithm, and maps the pupil center point on a display plane of a display device through a predetermined transform function.
