  • Publication number: 20190157497
    Abstract: A novel, low cost method for manufacturing flexible crystalline ultra-thin Si solar cells using previously fabricated inflexible crystalline Si solar cells. A stack of metal layers is coated onto a front side of previously completed inflexible crystalline Si solar cells. The stack serves as a bonding layer as well as an electrically conducting layer between the inflexible solar cell and the carrier substrate. The front side of the coated inflexible Si solar cell is bonded onto the carrier substrate. Back side layers from the starting inflexible solar cell are removed, as is much of the base layer, so that only a thin base layer remains, with the thin base layer and emitter region having a total thickness of between 1 ?m and 30 ?m and the final cell having a total thickness of about 10 to about 125 ?m.

  • Patent number: 10294283
    Abstract: Methods of producing a single-domain antibody (sdAb) include causing a bacteria to express the sdAb into cytoplasm of the bacteria, wherein the sdAb is expressed as a fusion protein with the acid tail of ?-synuclein; and then purifying the sdAb, wherein the fusion protein is expressed free of a periplasmic location tag.

  • Patent number: 10295614
    Abstract: The transfer function of a sensing device including a plurality of sensors is automatically adjusted based on a power level of an incident electromagnetic signal detected by the plurality of sensors. Each of the plurality of sensors is associated with a unique transfer function. An output from one of the plurality of sensors associated with a particular transfer function is automatically selected based on a power level of the detected incident electromagnetic signal. Responsive to a change in the power level of the detected electromagnetic signal, another output from a different one of the plurality of sensors associated with a different transfer function is selected. The transfer function is adjusted over time by automatically selecting outputs from different ones of the plurality of sensors based on changes in the power level of the detected incident electromagnetic signal.

  • Patent number: 10297168
    Abstract: Disclosed is a planar test bed comprising a planar surface and further comprising mechanical couplings in mechanical communication with the planar table and the supporting legs. The mechanical couplings are translatable to provide three degrees of freedom for orientation of the planar surface. A processor receives position and velocity information describing an object on the planar surface, and calculates a relative acceleration typically using a function aR=f(t,xR,vR,?t). The processor communicates with the mechanical couplings to establish an orientation where a local gravity vector projects onto the planar surface and generates acceleration with magnitude and direction substantially equal to the desired acceleration aR The operations occur in cyclic fashion so the desired accelerations and planar orientations are updated as an object transits over the planar surface.

  • Patent number: 10289761
    Abstract: According to exemplary practice of the present invention, the dynamic trajectory of a moving body is incrementally modeled using temporal and spatial relationships between the body and the target that the body pursues. In each time step, the body has starting positional coordinates and ending positional coordinates. The horizontal travel distance is calculated by taking into account the body's speed and the body's horizontal distance from the target. The vertical travel distance is calculated by taking into account the body trajectory's spatial derivative and the body's horizontal travel distance. The body's time-step-ending positional coordinates thus reflect the change, in accordance with the horizontal travel distance and the vertical travel distance, relative to the body's time-step-starting positional coordinates. Each succeeding time step repeats the computations whereby the starting positional coordinates are the ending positional coordinates of the preceding time step.
