The invention relates to holographic head-up displays, to holographic optical sights, and also to 3D holographic image displays. We describe a holographic head-up display and a holographic optical sight, for displaying, in an eye box of the display/sight, a virtual image comprising one or more substantially two-dimensional images, the head-up display comprising: a laser light source; a spatial light modulator (SLM) to display a hologram of the two-dimensional images; illumination optics in an optical path between said laser light source and said SLM to illuminate said SLM; and imaging optics to image a plane of said SLM comprising said hologram into an SLM image plane in said eye box such that the lens of the eye of an observer of said head-up display performs a space-frequency transform of said hologram on said SLM to generate an image within said observer's eye corresponding to the two-dimensional images.

Systems and methods for eyelid shape estimation are disclosed. In one aspect, after receiving an eye image of an eye (e.g., from an image capture device), an eye-box is generated over an iris of the eye in the eye image. A plurality of radial lines can be generated from approximately the center of the eye-box to an upper edge or a lower edge of the eye box. Candidate points can be determined to have local maximum derivatives along the plurality of radial lines. From the candidate points, an eyelid shape curve (e.g., for an upper eyelid or a lower eyelid) can be determined by fitting a curve (e.g., a parabola or a polynomial) to the candidate points or a subset of the candidate points.

The invention relates to a setting machine. The setting machine comprises a frame. One side of the frame is provided with a roller A. Fabric enters a setting box after orderly going through a pressing plate set, a first pressing roller set, and a second pressing roller set. One edge of a folded plate is used to press the fabric, and the other edge of the folded plate is fixedly connected to the frame through a spring. A group of spray pipes, which are alternately arranged, and a heating pressing roller set are arranged in the setting box. A swing mechanism is composed of a fixing rod, a first connection rod, a swing rod, and a second connection rod. After the fabric goes out of the setting box, the fabric orderly goes through a third pressing roller set and a fourth roller set and then is reeled on a roller B. Finally the fabric falls into a material storing box after going through a first pressing wheel and a second pressing wheel. The setting machine has the following advantages: (1) a pressing plate set is provided, and thus the fabric is flat before entering the setting box; (2) the spraying pipes and heating pressing rollers are alternately arranged, so the fabric will not be deformed by high temperature during the heating setting process and moreover the setting effect is good; (3) a swing mechanism and a leather belt wheel mechanism are combined to ensure that the fabric can be neatly stacked in the material storing box so as to achieve an automatic streamline structure.

The invention discloses a segmentation method based on S boxes. The segmentation method comprises the following contents: for a DES algorithm: replacing the S4 in an original algorithm with the S boxof the DESL or replacing all S boxes in the original algorithm with the S4 in the original algorithm; and for a CAST-128 algorithm: removing the "circulation key" operation of the original algorithm,and the operation of changing a "modulo plus key" and a "modulo minus key" into "exclusive or keys". Compared with the prior art, the differential analysis resistance of the DES algorithm is obviously improved after being replaced by the manner of the segmentation method disclosed by the invention. For the CAST-128 algorithm, the S box and the use sequence are modified, so that a new round function can resist the appearance of high-probability differential features with a probability of 2-7. Therefore, the modified algorithm can maintain the original differential analysis resistance and meanwhile can resist side channel attacks.

The invention pertains to biological technique and gene treatment field, and discloses a dual tumor targeting replicative oncolytic adenouiruses, which is dually targeting, and controls the expression of virus early protein EIA and replication of virus by the synergism of specific tumor promoter and a CR2 region of a target deleted Rb protein.
