  • Publication number: 20150303546
    Abstract: A new class of antennas and microwave components are introduced. In this approach a high-permittivity dielectric film is applied (i.e. printed) on a dielectric substrate, which may be grounded. By changing the shape of the high-permittivity film, different microwave devices (e.g. waveguides, filters, couplers, and antennas) are produced. By changing the size and permittivity of the high-permittivity film and dielectric substrate, these elements are designed at different frequencies for different applications. Highly-efficient microwave devices can result due to the absence of surface currents.

  • Patent number: 8953070
    Abstract: Apparatus, methods and systems for bridging between commercially available, high-speed image sensors and low cost, low power microcontrollers. An image sensor interface processor is provided for controlling an image sensor, and receiving and storing image data. A microcontroller (or other general purpose or image processor) can communicate with the image sensor interface processor, to access pixel data in a random access fashion through a parallel memory access interface at any speed desired by the microcontroller. Moreover, automatic power management of the image sensor can be provided by the image sensor interface processor. In some alternative embodiments, the described image sensor interface processor may be integrated into the image sensor itself, or a microcontroller, or some other intermediate device.

  • Patent number: 8884100
    Abstract: Nucleic acid molecules from Cannabis sativa (cannabis, hemp, marijuana) have been isolated and characterized, and encode polypeptides having aromatic prenyltransferase activity. Specifically, the enzyme, CsPT1, is a geranylpyrophosphate olivetolate geranyltransferase, active in the cannabinoid biosynthesis step of prenylation of olivetolic acid to form cannabigerolic acid (CBGA). Expression or over-expression of the nucleic acids alters levels of cannabinoid compounds. The polypeptides may be used in vivo or in vitro to produce cannabinoid compounds.

  • Patent number: 8835665
    Abstract: Methods for recovery of recyclable water and/or fermentation co-products from thin stillage process streams. Microbial metabolites plant derivatives and/or plant extractives are removed from thin stillage after which water is recovered and recycled. Thin stillage is commingled with polar organic solvents or with oil to react microbial metabolites, plant derivatives and/or plant extractives. The reacted organic solvents are then separated from the processed thin stillage. Thin stillage may be commingled with an oil to re act with certain organic compounds, after which, the reacted oil is separated from the processed thin stillage is further extracted with one or more polar organic solvents. Alternatively, thin stillage may be first processed with one or more polar organic solvents, and then processed with an oil. Useful organic compounds may be recovered from the reacted oil and reacted organic solvents.

  • Patent number: 8758999
    Abstract: The present invention relates to primers for the universal amplification and detection of Archaea, which primers are designed based on a multiple sequence alignment of Archaea Type II chaperonin (thermo-some) genes. For detection of Archaea having templates with a GC content of below 60%, primers are designed so that inosine residues are found at degenerate positions. For amplification of higher GC content templates, degenerate positions are replaced with specific nucleotide bases found in the high GC organism. The primers are useful for detecting, identifying and quantifying Archaea in a sample and for determining a phylogenetic relationship of a test Archaea organism.
