  • Adenoviral vector
    Patent number: 11970709
    Abstract: The present invention provides recombinant adenoviral vectors, immunogenic compositions thereof and their uses in medicine. In particular, the present invention provides an adenoviral vector comprising the genome of an adenovirus other than AdHu5 and AdY25, wherein the genome of the adenovirus has been modified such that the vector lacks the native E4 locus of the adenovirus and comprises heterologous E4Orfl, E4Orf2 and E4Orf3 coding regions from AdY25.

  • Method for electroporation controlled by electrical impedence measurements
    Patent number: 11911611
    Abstract: The present invention provides a system and method for measuring an impedance of one or more target cells before and after an electroporation protocol has been applied to the one or more target cells. The result of the impedance measurement provides a feedback control that can be implemented during and/or after the electroporation protocol to customize the electrical treatment for a particular target cell or cellular tissue.

  • Seed spacing device for an agricultural planter and related systems and methods
    Patent number: 11277961
    Abstract: Various methods, systems, and devices for flexible and accurate seed spacing control in a seed planting system. The various embodiments receive singulated seed from a metering device and control movement of the seed toward a seed spacing device that receives the seed. The seed spacing device, which is disposed near the soil surface, independently controls the ejection of the seed from the device and thus the spacing of the seed in the furrow.

  • Controlled Air Pulse Metering Apparatus For An Agricultural Planter And Related Systems And Methods
    Publication number: 20200359552
    Abstract: The devices, systems, and methods herein use air pressure to dispense seed into the ground in a controlled manner. In certain embodiments, a valve is actuated to push a single seed out of a seed chamber. The seed can be conveyed from the metering housing and through a seed delivery apparatus to the furrow at high speed. The seed is rapidly conveyed from the seed chamber to the furrow by a precisely controlled air pulse to eliminate variation enable high planting speeds.

    Publication number: 20190098827
    Abstract: The devices, systems, and methods herein use air pressure to dispense seed into the ground in a controlled manner. In certain embodiments, a valve is actuated to push a single seed out of a seed chamber. The seed can be conveyed from the metering housing and through a seed delivery apparatus to the furrow at high speed. The rapid conveyance from the seed chamber to the furrow by the precisely controlled air pulse eliminates the variation from known metering and delivery technologies and enables higher planting speeds.
