Patent number: 11630317Abstract: A collimator includes a front lens sleeve, a clamping groove disposed on the front lens sleeve, a linking sleeve fastened on the clamping groove, a snapping groove disposed on the linking sleeve distal the front lens sleeve, a connection sleeve slidably connected to the snapping groove, a constraint sleeve disposed on the snapping groove, and a limit groove disposed on an inner surface of the constraint sleeve. The components cooperate with each other. The test chart is tilted relative to the optical axis of the lens and makes the test chart distributed at different distances along the axis. When using the camera to shoot the collimator, the clarity of different components reflects the relative focus position of the camera so as to detect the vehicle mounted camera.Type: GrantFiled: October 13, 2022Date of Patent: April 18, 2023Assignee: Shenzhen General Core Optoelectronics Co., Ltd.Inventors: Zhongfei Chen, Minglin He, Shuaitian Jiang, Jianzhi Song, Deyu Li

Patent number: 9283242Abstract: The present invention provides pharmaceutical compositions comprising a dihydro base described herein (e.g., compound DHdC). The dihydro base may show multiple tautomerism and may increase mutation of an RNA and/or DNA of a virus or cancer cell. The dihydro base may be used to reduce DNA methylation (e.g., in a cancer cell). The present invention also provides kits including the inventive pharmaceutical compositions and methods of treating a viral infection (e.g., influenza, HIV infection, or hepatitis C) or cancer using the pharmaceutical compositions or kits.Type: GrantFiled: January 22, 2014Date of Patent: March 15, 2016Assignee: Massachusetts Institute of TechnologyInventors: John M. Essigmann, Deyu Li, Katherine J. Silvestre

Patent number: 8093628Abstract: Fluidic nanotube devices are described in which a hydrophilic, non-carbon nanotube, has its ends fluidly coupled to reservoirs. Source and drain contacts are connected to opposing ends of the nanotube, or within each reservoir near the opening of the nanotube. The passage of molecular species can be sensed by measuring current flow (source-drain, ionic, or combination). The tube interior can be functionalized by joining binding molecules so that different molecular species can be sensed by detecting current changes. The nanotube may be a semiconductor, wherein a tubular transistor is formed. A gate electrode can be attached between source and drain to control current flow and ionic flow. By way of example an electrophoretic array embodiment is described, integrating MEMs switches.Type: GrantFiled: February 7, 2008Date of Patent: January 10, 2012Assignee: The Regents of the University of CaliforniaInventors: Peidong Yang, Rongrui He, Joshua Goldberger, Rong Fan, Yiying Wu, Deyu Li, Arun Majumdar

Patent number: 7211143Abstract: Methods of fabricating uniform nanotubes are described in which nanotubes were synthesized as sheaths over nanowire templates, such as using a chemical vapor deposition process. For example, single-crystalline zinc oxide (ZnO) nanowires are utilized as templates over which gallium nitride (GaN) is epitaxially grown. The ZnO templates are then removed, such as by thermal reduction and evaporation. The completed single-crystalline GaN nanotubes preferably have inner diameters ranging from 30 nm to 200 nm, and wall thicknesses between 5 and 50 nm. Transmission electron microscopy studies show that the resultant nanotubes are single-crystalline with a wurtzite structure, and are oriented along the <001> direction. The present invention exemplifies single-crystalline nanotubes of materials with a non-layered crystal structure. Similar “epitaxial-casting” approaches could be used to produce arrays and single-crystalline nanotubes of other solid materials and semiconductors.Type: GrantFiled: December 8, 2003Date of Patent: May 1, 2007Assignee: The Regents of the University of CaliforniaInventors: Peidong Yang, Rongrui He, Joshua Goldberger, Rong Fan, Yi-Ying Wu, Deyu Li, Arun Majumdar
