  • Patent number: 10380751
    Abstract: A robot vision system for generating a 3D point cloud of a surrounding environment through comparison of unfiltered and filtered images of the surrounding environment. A filtered image is captured using a camera filter which tends to pass certain wavelength bandwidths while mitigating the passage of other bandwidths. A processor receives the unfiltered and filtered images, pixel matches the unfiltered and filtered images, and determines an image distance for each pixel based on comparing the color coordinates determined for that pixel in the unfiltered and filtered image. The image distances determined provides a relative distance from the digital camera to an object or object portion captured by each pixel, and the relative magnitude of all image distances determined for all pixels in the unfiltered and filtered images allows generation of a 3D point cloud representing the object captured in the unfiltered and filtered images.

  • Publication number: 20190242838
    Abstract: A method for non-invasively measuring the impedance of a plasma discharge. Parallel anode and cathode electrodes are connected to a DC voltage source that ignites and sustains a plasma between the anode and cathode. A network analyzer applies a frequency-swept AC signal superimposed onto the DC voltage applied to the electrodes. The voltage of the AC signal reflected by the plasma is measured by the network analyzer through one of the electrodes used to sustain the plasma and is used to find the complex impedance of the plasma as a function of the applied AC frequency. Since the electrode serves dual purposes, the insertion of an additional physical probe that could introduce perturbations or contaminate the discharge is not necessary.

  • Publication number: 20190245111
    Abstract: A method for making an ultra-thin, flexible crystalline silicon solar cell from thick, inflexible cells. A thick, inflexible cell having a plurality of electrical contacts on the back side thereof is adhered to a mount by means of a temporary bonding adhesive tape and a thickness of the mounted stack. A thickness of the bonding tape and the back-side contacts is determined and compared to a desired thickness of the final cell. Excess material is ground from the front side of the stack to obtain a thinned stack having the desired thickness and the thinned stack is removed from the mount to produce an ultra-thin, flexible rear-contact Si solar cell having a total thickness of less than 80 ?m and a bending radius of less than 20 mm. The front surface can be textured, with a passivation layer and/or a dielectric layer being deposited thereon.

  • Patent number: 10370121
    Abstract: A launcher for an unmanned aircraft may comprise: a launch rail, a carriage, pair of pulley drivers, and a cable and pulley system. The pulley drivers may produce opposing pulley drive forces, which may be converted into a single launching force via the cable and pulley system for launching the carriage. The cable and pulley system may comprise: launch rail pulleys, pulley block pulleys, cam pulleys, drive cables, and one or more winches. Embodiments of the launcher may apply a constant force to the aircraft uniformly over the launch distance, such that the unmanned aircraft may be propelled within a relatively short distance by applying energy to the aircraft in the smallest period of time and without exceeding the aircraft's acceleration limits.

  • Publication number: 20190233799
    Abstract: This application is directed generally to foot-and-mouth disease virus (FMDV) 3C proteases that have been modified by mutating a polynucleotide sequence coding for the FMDV 3C protease. The modified FMDV proteases exhibit proteolytic activity on FMDV P1 precursor protein and exhibit a reduction in one or more toxic or inhibitory properties associated with an unmodified FMDV 3C protease on a host cell used to recombinantly produce it. Vectors carrying polynucleotides encoding modified FMDV 3C protease sequences can induce production of FMDV virus-like particles in a host cell when expressed in the host cell. The modified FMDV 3C proteases can generally be used to produce immunogenic FMDV preparations capable of inducing an immune response against FMDV.
