A draping system provides a continuous sterile field between a patient incision area and one or more medical practitioners. The draping system has a quick release system incorporated into the drape that enables a medical practitioner to separate from the continuous sterile field without disrupting the sterile field around the practitioner or the patient. The draping system may include an abbreviated practitioner gown, a drain and an integral patient incision area or a flap for extending the continuous sterile field around to one or more additional operating room tables. A modular drape and gown system extends the sterile field beyond the operating table allowing practitioners to couple to the extended field. A tent provides an enclosed sterile field useful in mobile or other non operating room surgical environments. Integral lighting and information displays facilitate field surgical procedures.

An optical system is provided for creating a mosaic image of a large field of view through a microscope at fast refresh rates of about 25 Hz with a high resolution that is free of blurring or aberrations. The optical system includes an objective lens assembly (20), an iris (30), one or more scanning mirrors (40) for high-speed scanning, one or more imaging lenses and irises (50, 60, 80), and a high-speed imaging device (70) arranged in that order from an object. The optical system also includes a mechanism for processing and constructing scanned and captured images into a mosaic image.

The invention addresses the lack of comprehensive and quantitative methods for measurements of unwanted visual “mura” effects in displays and image sensors. Mura is generated by errors that are significantly smaller than what is needed for the function of the device, and sometimes smaller than the random variations in the patterns or structures. Capturing essentially all mura defects in a workpiece in a short time requires a daunting combination of sensitivity, statistical data reduction and speed. The invention devices an inspection method, e.g. optical, which maximizes the sensitivity to mura effects and suppresses artifacts from the mura inspection hardware itself and from noise. It does so by scanning the sensor, e.g. a high-resolution camera, creating a region of high internal accuracy across the mura effects. One important example is for mura related to placement errors, where a stage with better than 10 nanometer precision within a 100 mm range is created. A sampling scheme reduces the data volume and separates between instrument errors and real defects based on their different geometrical signatures. The high-resolution camera scans sparse lines at an angle to the dominating directions of expected mura defects, creating extended sensor fields with high internal precision, and quantifying edge placements in small windows in said extended fields. The mura is classified and presented as type, location and severity.

In an embodiment of the invention, a semiconductor device includes a first region having a first doping type, a channel region having the first doping type disposed in the first region, and a retrograde well having a second doping type. The second doping type is opposite to the first doping type. The retrograde well has a shallower layer with a first peak doping and a deeper layer with a second peak doping higher than the first peak doping. The device further includes a drain region having the second doping type over the retrograde well. An extended drain region is disposed in the retrograde well, and couples the channel region with the drain region. An isolation region is disposed between a gate overlap region of the extended drain region and the drain region. A length of the drain region is greater than a depth of the isolation region.

The present invention discloses a realization method for wireless link control layer protocol data unit. The length limit of a configured wireless link control layer protocol data unit RLC PDU is Lmax_PDU. When the sum LSDU_header of the length of a wireless link control layer service data unit RLC PDU and the length of header information is not greater than the Lmax_PDU, the header information is added to an integral RLC SDU for generating an RLC PDU, a value of an HE field in the header information is used to indicate the next field as the content of an integral RLC SDU. When the sum LSDU_header of the length of the RLC SDU length and the header information length is greater than the Lmax_PDU, the integral RLC SDU is segmented and then added to the header information for generating the RLC PDU, and the value of a header extended field HE in the header information is used to indicate the next field information. The present invention decides whether to support that the RLC PDU is generated with the integral and / or segmented RLC SDU in a serial connection mode or not through configuration.

The invention belongs to the technical field of microimaging and provides a method, an optical module and a system for extended field depth three-dimensional nanoscale-resolution imaging. The method comprises the following steps of 1, building the optical module having a double-helix point spread function and defocusing grating multistage imaging properties, 2, carrying out imaging of a molecule needing to be detected by the optical module to obtain a double-helix image, 3, determining a horizontal position of the molecule needing to be detected according to positions of middle points of double-helix sidelobes of the double-helix image, and 4, determining an axial position of the molecule needing to be detected according to a rotation angle of a connection line of centers of the double-helix sidelobes of the double-helix image, and the positions of the middle points of the double-helix sidelobes. Through combination of double effects of the double-helix point spread function and the defocusing grating multistage imaging, the method extends a field depth and improves a resolution ratio. The method can be used for dynamic range imaging of subcellular fractions having any depth values in a whole cell, can produce dynamic function images of multiple moving molecules, and has an important meaning for high-level understanding of a rule and a relationship between a subcellular structure and a cell function change.

An equation transforming unit triangular transforms a matrix M and a vector v to generate a matrix M′ and a vector v′ for a system of linear equations M′x=v′ in n unknowns that has an equivalence relation with a system of linear equations Mx=v in n unknowns. The triangular transformation is such that the matrix M is transformed into an upper triangular matrix without the diagonal elements of the matrix M being changed to 1. An inverting unit calculates the inverses of the diagonal elements of the matrix M′. An equation computing unit finds the solutions of the system of linear equations M′x=v′ using the matrix M′, the vector v′, and the calculated inverses of the diagonal elements. An inverse computing unit computes the inverse I of an element y in GF(q) which is an extension field of a finite field GF(p), based on the solutions found by the equation computing unit.
