  • Patent number: 11950392
    Abstract: Described herein are DC-DC converters with electronic module cooling units used for air-convection cooling of some components of power electronic modules and conductive cooling of other components, e.g., switching sub-modules. A cooling unit may have a heat exchanger and a cooling plate, thermally coupled to one or more heat exchangers and one or more switching sub-modules. For example, the cooling plate can be positioned between and thermally coupled to heat exchangers. One fan can direct air through one heat exchanger and to one power electronic module as a part of convection cooling. An additional fan can direct air through the second heat exchanger and to the second power electronic module. The cooling plate can be also positioned between and thermally coupled to switching sub-modules of these power electronic modules thereby enabling conductive cooling. The plate-cooling liquid is pumped through the cooling plate.

  • Patent number: 11801994
    Abstract: A receptacle is provided for holding a quantity of solid material. The receptacle includes a container having an open end, and a gate operably connected to the container so as to be rotatable to a closed position structured to prevent solid material from exiting the container through the open end. The gate includes a locking arm mounted thereon. A latching mechanism is operably connected to the container and includes a latch rotatable to a latched orientation structured to contact the locking arm to prevent the gate from being rotated out of the closed position. The locking arm is structured to move rearwardly and upwardly during rotation of the gate out of the closed position. The latch is structured so that contact between the latch and the locking arm when the latch is in the latched orientation prevents rearward and upward movement of the locking arm.

  • Publication number: 20060123050
    Abstract: The present invention relates to data mapping and involves the mapping of at least one feature from one data set to a corresponding feature in a second data set. Individual points of the features are initially mapped and an transformation for mapping the entire feature is derived from the individual mappings. The feature mapping may be used to enhance vehicle navigation, in feature tracking algorithms, and in image processing systems.

  • Publication number: 20040214318
    Abstract: The present invention provides a method for enhancing the production of RNAs or proteins in a plant host using either non-native 5′ untranslated sequences or artificial leader sequences. Preferably, commercially useful proteins, polypeptides, or fusion products thereof are produced, such as, enzymes, antibodies, hormones, pharmaceuticals, vaccines, pigments, anti-microbial polypeptides, and the like. The non-native 5′ untranslated enhancers may also be effective in many different types of transcription or translation systems, such as bacterial and animal systems.

  • Publication number: 20040170606
    Abstract: Vaccines and diagnostic composition are made and used for preventing, treating and detecting antigens from a papilloma virus, ebola virus, HIV virus, Rift Valley Fever virus or a parvovirus. The epitopes of these viruses are produced as genetically engineered fusion peptides in plants by infection with a recombinant tobamovirus vectors to express fusion proteins containing the epitope peptides.

  • Publication number: 20030049228
    Abstract: The invention provides an expression system for foreign peptides by using a polynucleotide which encodes a promoter which transcribes a mRNA containing at least two open reading frames, from which an internal ribosome entry site directs the translation of one of the open reading frames. In addition, the invention provides a method of expressing a foreign peptide in a host using the expression system of the invention.
