This invention disclosed an anti-HPV drug and its applications in preparing medicines for treatment of HPV (human papilloma virus) infection. This drug was characterized by using human rabies vaccine as its active ingredient and being produced by adding pharmacologically acceptable carriers. This invention also disclosed drug applications in preparing medicines for treatment of HPV infection, i.e. new applications of human rabies vaccines for preparing medicines against HPV infection. The anti-HPV drug described in this invention (i.e. human rabies vaccine) had obvious treatment effects on HPV infection. According to the animal tests and preclinical observation, this drug provided satisfactory and beneficial effects and had the characteristics of safety, effectiveness and nearly no recurrence after treatment; the negative-conversion rate in patients with positive HPV-infection reached 90% after treatment.
摘要:
A method and system for compensating for motion blur in optical navigation adds a correction offset to an image navigation value to adjust for varying velocities along a moving web. Reference and comparison images are acquired at different times from a moving web. An optical navigation value is computed representative of the movement of the web from the reference image to the comparison image. Blur distances for the two images can be calculated. A navigation error correction value is computed as one-half the difference between the reference blur distance and the comparison blur distance. A compensated navigation value is computed by adding the error correction value to the computed navigation value to compensate for varying web velocities.

A collapsible computer desk includes a desktop, a left frame, a right frame, two inner side-plates, a lower frame, plural middle support plates, a back plate and a drawer. The inner side-plates are secured to the desktop and also secured to the both ends of the lower frame. The back plate is connected to the back portion of the lower frame and the bottom surface of the desktop. Further comprised is a plurality of assembled closures. Each assembled closure is constructed of a male closure and a female closure. The male closures of the plurality of the closures are fixedly secured onto vertical plates of the left and right frames respectively, while the female closures are fixedly secured onto the both ends of the lower frame respectively. Each male closure detachably engages the corresponding female closure.
摘要:
A method for determining an offset vector. The method includes obtaining an image of a first feature. An image of a second feature is also obtained. Also, a combination image of the first feature and the second feature is obtained. A plurality of composite images is utilized to determine an accurate offset vector between the first feature and the second feature in the combination image. The plurality of composite images is based on the image of the first feature and the image of the second feature.
摘要:
A reference image of an area of a print media is captured at approximately a first time by an image acquisition system. A first application of ink is applied onto the print media area by a printing assembly at the first time. A comparison image of the print media area is captured at a second time by the image acquisition system subsequent to the first application of ink onto the print media area. The reference image and the comparison image are processed to determine a relative displacement of a feature pattern on the print media between approximately the first time and the second time. A second application of ink from the printing assembly onto the print media is adjusted based on the determination.

Lithography tools and substrates are aligned by generating geometric interference patterns using optical gratings associated with the lithography tools and substrates. In some embodiments, the relative position between a substrate and lithography tool is adjusted to cause at least one geometric shape to have a predetermined size or shape representing acceptable alignment. In additional embodiments, Moiré patterns that exhibit varying sensitivity are used to align substrates and lithography tools. Furthermore, lithography tools and substrates are aligned by causing radiation to interact with optical gratings positioned between the lithography tools and substrates. Lithography tools include an optical grating configured to generate a portion of an interference pattern that exhibits a sensitivity that increases as the relative position between the tools and a substrate moves towards a predetermined alignment position.

A contact lithography apparatus, system and method use a hydraulic deformation to facilitate pattern transfer. The apparatus, system and method include a spacer that provides a spaced apart proximal orientation of lithographic elements, and a hydraulic force member that provides the hydraulic deformation. One or more of the lithographic elements and the spacer is deformable, such that hydraulic deformation thereof facilitates the pattern transfer.
