  • Patent number: 10994991
    Abstract: Methods are provided for manufacturing well-controlled, solid-state nanopores and arrays of well-controlled, solid-state nanopores by a cyclic process including atomic layer deposition (ALD), or chemical vapor deposition (CVD), and etching. One or more features are formed in a thin film deposited on a topside of a substrate. A dielectric material is deposited over the substrate having the one or more features in the thin film. An etching process is then used to etch a portion of the dielectric material deposited over the substrate having the one or more features in the thin film. The dielectric material deposition and etching processes are optionally repeated to reduce the size of the features until a well-controlled nanopore is formed through the thin film on the substrate.

    Abstract: To provide a video projector which improves visibility in response to changes in projection environment, a video projector has an initial level setter, a level adjuster, a projection display, an image capture, and a projection histogram calculator. The initial level setter performs a prescribed initial level setting on an input video signal and outputs an initial display signal. The level adjuster adjusts the level of the initial display signal on the basis of a projection image and outputs a display signal. The image capture captures the projection image projected on a projection surface by the projection display based on the display signal. The projection histogram calculator prepares a projection histogram for each color. The level adjuster adjusts the level of the initial display signal for each color on the basis of the projection histogram.
