  • Patent number: 8383881
    Abstract: A method for producing polyploid plants of orchids includes the steps of: providing a protocorm or protocom-like body (PLB) of an orchid, the protocorm or PLB having an upper portion with a growing point and a lower portion without any growing point; cutting the protocorm or PLB approximately at a point of half height to separate the upper portion; subculturing the lower portion of the protocorm or PLB in an inducing medium, and putting a cut surface of the lower portion of the protocorm or PLB to face upward so that one or more next-generation PLBs grow from the cut surface of the lower portion. The method characterized in using no antimicrotubule agent can simplify the entire process of orchid polyploidy breeding, and can be used in mass-production of the stable polyploid plants.

  • Publication number: 20130008159
    Abstract: A liquid pump of a screw expander is disclosed, applicable to an Organic Rankin Cycle (ORC). The liquid pump of a screw expander includes a semi-sealed or fully sealed shell. An expander unit and a liquid pump unit are disposed in the shell. The expander unit includes a screw rotor, and the liquid pump unit includes a screw rotor. The rotor of the expander unit is fixedly connected to the rotor of the liquid pump unit. The rotor of the liquid pump unit rotates under driving of the rotor of the expander unit. In the liquid pump of a screw expander applied to the ORC, since a resistance torque of the female rotor is small, the liquid pump does not wear even when the liquid viscosity is low, contributing to high reliability of the liquid pump. Meanwhile, the liquid pump is driven by the screw expander, thereby further improving power generation efficiency of the ORC.

  • Patent number: 8321761
    Abstract: A memory module includes a plurality of register files. Each register file is associated with a set of error-correcting code (ECC) bits and ECC check/correct logic that can provide error-correcting functionality, if required. When error-correcting functionality is not required, ECC bits are grouped together to form additional register files, thereby providing additional storage space.

  • Patent number: 8266383
    Abstract: One embodiment of the present invention sets forth a technique for processing cache misses resulting from a request received from one of the multiple clients of an L1 cache. The L1 cache services multiple clients with diverse latency and bandwidth requirements, including at least one client whose requests cannot be stalled. The L1 cache includes storage to buffer pending requests for caches misses. When an entry is available to store a pending request, a request causing a cache miss is accepted. When the data for a read request becomes available, the cache instructs the client to resubmit the read request to receive the data. When an entry is not available to store a pending request, a request causing a cache miss is deferred and the cache provides the client with status information that is used to determine when the request should be resubmitted.

  • Patent number: 8139071
    Abstract: An apparatus and method for buffering graphics data are described. In one embodiment, a graphics processing apparatus includes a storage unit and a reorder control unit that is connected to the storage unit.

  • Publication number: 20110072243
    Abstract: One embodiment of the present invention sets forth a technique for collecting operands specified by an instruction. As a sequence of instructions is received the operands specified by the instructions are assigned to ports, so that each one of the operands specified by a single instruction is assigned to a different port. Reading of the operands from a multi-bank register file is scheduled by selecting an operand from each one of the different ports to produce an operand read request and ensuring that two or more of the selected operands are not stored in the same bank of the multi-bank register file. The operands specified by the operand read request are read from the multi-bank register file in a single clock cycle. Each instruction is then executed as the operands specified by the instruction are read from the multi-bank register file and collected over one or more clock cycles.

In one embodiment, electromagnetic radiation is guided and/or emitted at multiple distinct wavelengths, including emission in the form of an essentially continuous band, in some cases covering at least 150 nanometers. In another embodiment, methods for splitting a waveguide core and/or the joining of at least two waveguide cores in a waveguide are provided. In yet another embodiment, the invention includes the use of thermal gradients to generate a waveguide and/or to change the properties of waveguides. Embodiments of the waveguides may be used for optical detection or spectroscopic analysis.
