  • Patent number: 6799317
    Abstract: A method for transparently handling messages originating from local shared memory and from an external source. A device driver allows the local sender to identify and wake up a waiting receiver task thread, simulating a packet arrival hardware interrupt. Upon awakening, the receiver task thread examines both shared memory and hardware message queues. The method can use a software routine that simulates handling of an occurrence of a hardware interrupt. The method invokes a local notify system service module that passes a window number identifying a receiving task. The method invokes a wake thread module that passes awakens a thread associated with the window number, and examines the shared memory buffer for receipt of the local source message. The method then copies the local source message from the shared memory buffer to the receiving task.

  • Patent number: 6692746
    Abstract: Superantigens, including Staphylococcal enterotoxins streptococcal pyrogenic exotoxins (SpE's), biologically active fragments and homologues thereof and fission proteins of the native superantigens, homologues and fragments, are useful agents for killing tumor cells, enhancing antitumor immunity and for treating tumors in a tumor-bearing subject. In particular, a subject having a tumor is treated with a tumoricidally effective amount of a superantigen, such as a SE or SpE, or a biologically active homologue thereof, fusion protein thereof or a fusion protein of the homologue. These agents stimulate T cells, leading to increased antitumor immunity and killing of tumor cells.

  • Patent number: 6625797
    Abstract: The compilation of a high-level software-based description of an algorithm into efficient digital hardware implementation(s) is addressed. This is done through the definition of new semantics for software constructs with respect to hardware implementations. This approach allows a designer to work at a high level of abstraction, while the semantic model can be used to infer the resulting hardware implementation. These semantics are interpreted through the use of a compilation tool that analyzes the software description to generate a control and data flow graph. This graph is then the intermediate format used for optimizations, transformations and annotations. The resulting graph is then translated to either a register transfer level or a netlist-level description of the hardware implementation.

  • Patent number: 6558943
    Abstract: A solid state fermentation (SSF) method is provided which is effective for both small- and large-scale fungal cultivation. Also provided is SSF media for fungal cultivation. The media preferably contains a carbon source and nitrogen source to provide a carbon to nitrogen ratio of about 5:1 to about 25:1 by weight. The media may also contain a vitamin and an inorganic substance. A preferred SSF medium contains malt extract, yeast extract, peptone, glucose, water, solid base, and calcium carbonate or gypsum. Before propagating fungal mycelia in the SSF medium, the mycelia may be pre-cultivated in a solid culture medium and then in a liquid medium. Although the SSF method can be used in growing most fungi, preferred fungi include Cordyceps sinensis, Ganoderma lucidum, Antrodia camphorata, Trametes versicolor, and Agaricus blazei. The SSF method not only produces high yield of fungi, but also stimulates the production of fungal metabolites, particularly the kinds with pharmaceutical and medicinal activities.

  • Patent number: 6558488
    Abstract: The invention relates to a method of making pourable, plastic-bound explosive charges or rocket propellants, to which a metal powder having essentially spherically shaped grains is added. To avoid an increase in the viscosity of the explosive charge or the rocket propellant through polar groups attached to the surface of the metal powder, it is suggested according to the invention that the polar groups of the metal powder be saturated with SiR3 groups (Si=silane; R=organic residue) before the metal powder is added to the explosive mixture. As a result, the polar groups can no longer react with the isocyanates of the explosive charge or the rocket propellant and the specific surface of the respective metal powder, as well as the viscosity of the charges, is reduced.

  • Patent number: 6542370
    Abstract: A heat dissipating device has a conductor holder and a heat conductor. The conductor holder is securely attached to the CPU base and has a through hole. The heat conductor is securely connected to the through hole in the conductor holder and contacts with the CPU. The heat conductor comprises multiple heat conductive elements made of a material with good heat conductivity. One end of the heat conductive elements are twisted together to form a bound section on the first end of the heat conductor. The other end of each heat conductive element is far away from the other element so as to form an expansion section on a second end of the heat conductor. In such an arrangement, the heat generated by the CPU can be efficiently dissipated from the expansion section of the heat conductor.
