  • Patent number: 10985699
    Abstract: A differential constructive wave oscillator device including a single, continuous differential transmission line that is arranged into first and second parallel traces in the form of a Mobius loop. The continuous transmission line includes first and second crossover points, each of which provides for a point of inflection between the first and second traces. In each stage of the device, both the first and second traces of the transmission line carry the forward traveling wave signal from a differential input port to a differential output port. Each phase includes a differential delay section that provides for a phase shift between a signal on the first trace and a signal on the second trace. Each phase additionally includes a differential feedback amplifier that amplifies the forward traveling wave signal at the differential output port, generates a differential feedback signal, and routes the differential feedback signal to the differential input port.

  • Publication number: 20170127674
    Abstract: Alexandrian laurel (Danae racemosa L.) is a highly demanded evergreen shrub. However, seed germination often takes up to 12 to 18 months with a germination rate of only about 20%. Also, due to its slow-growth rate, it typically takes up to six years to produce a saleable one-gallon size plant. Germinating seeds in the presence of cytokinins and/or auxins increased in vitro shoot multiplication and seedling quality enhancement. Benzyladenine was found to balance seedling development by simultaneously accelerating shoot growth and slowing down root growth, whereas thidiazuron significantly promoted shoot multiplication and proliferation by producing 5-30 shoots per seed.

  • Patent number: 8211485
    Abstract: The present invention relates to the use of a solution containing at least one endopeptidase to substantially reduce or completely eliminate allergenic proteins contained in the peanut (Arachis hypogea). In particular, the direct application of a solution containing at least one endopeptidase to either raw, blanched, or roasted peanuts or peanut products or derivates, has been shown to substantially reduce or completely eliminate the activity of allergenic proteins. The treated peanuts showed no degradation in quality or sensory acceptability, and have the flavor and aroma of natural whole peanuts. Hypoallergenic or non-allergenic peanuts produced in accordance with the present invention may be used as ingredients in various food products and other edible materials.

  • Patent number: 7075424
    Abstract: A sensor array for non-destructively monitoring a structure to detect a critical structural event. The sensor array includes a plurality of discrete sensor nodes, each of the discrete sensor nodes producing an electrical signal in response to a structural event. A signal adder is electrically connected to the plurality of discrete sensor nodes for receiving and combining the electrical signal from each of the discrete sensor nodes to form a single sensor array output signal. A signal processing module then receives and processes the single sensor output signal. In the preferred embodiment, the signal processing module uses the time interval between the electrical signals from each of the discrete sensor nodes formed into a single sensor array output signal to calculate the location of the critical structural event. Also, in the preferred embodiment, a data collection system is located downstream of the sensor processing module.

  • Patent number: 6423230
    Abstract: A method for improving the permeate flux of a cross-flow membrane filter having at least two membrane ports through which the feed solution passes and at least two permeate outlets. The method includes the steps of establishing a first flow of a feed solution in a first direction through the membrane ports of the cross-flow membrane filter; reversing the first flow after a predetermined time to a second flow direction opposite that of the first flow direction; and repeating steps (a) and (b) until the permeate flux through the cross flow membrane filter reaches an unacceptable level by using a feed pump and a valve manifold assembly located between the feed pump and the cross flow membrane filter for selectively reversing the flow of the feed solution through the membrane ports of the cross flow membrane filter.
