Patent number: 11995827Abstract: An image display method includes: processing a first image to obtain a first feature image, the first image being an image of a local area of a smear captured by a microscope, and the local area including multiple objects to be tested; obtaining a second feature image corresponding to the first feature image, the second feature image and the first feature image having a same size; obtaining a third feature image according to an image obtained by overlaying the first feature image and the second feature image, a feature point in the third feature image indicating a possibility that one of the multiple objects is an abnormal object; obtaining a second image according to the third feature image; and displaying the second image superimposed on the first image.Type: GrantFiled: April 11, 2022Date of Patent: May 28, 2024Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Zhaoxuan Ma, De Cai, Hu Ye, Xiao Han, Yanqing Kong, Hongping Tang

Patent number: 9178129Abstract: An environmental sensor comprises a graphene thin-film as an environmentally responsive material. Such graphene films exhibit negative temperature coefficients (NTC), resulting in rapid decreases in electrical resistance as temperature increases, as well as a much faster response time than any other NTC material reported in the literature. The graphene film is also mechanically stable under bending, and, therefore, can be adapted for use in a mechanical sensor or pressure sensor, because the electrical resistance of the graphene film changes upon deflection and/or changes in pressure. The electrical resistance of the graphene film also increases in response to increases in environmental humidity. The electrical resistance changes of the graphene film can also be used as a sensing mechanism for changes in chemical and biological parameters in the environment of the sensor.Type: GrantFiled: October 14, 2013Date of Patent: November 3, 2015Assignee: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGYInventors: Woo Young Lee, Linh Tung Le, De Kong

Patent number: 9165721Abstract: An electrical component includes an inkjet-printed graphene electrode. Graphene oxide flakes are deposited on a substrate in a graphene oxide ink using an inkjet printer. The deposited graphene oxide is thermally reduced to graphene. The electrical properties of the electrode are comparable to those of electrodes made using activated carbon, carbon nanotubes or graphene made by other methods. The electrical properties of the graphene electrodes may be tailored by adding nanoparticles of other materials to the ink to serve as conductivity enhancers, spacers, or to confer pseudocapacitance. Inkjet-printing can be used to make graphene electrodes of a desired thickness in preselected patterns. Inkjet printing can be used to make highly-transparent graphene electrodes. Inkjet-printed graphene electrodes may be used to fabricate double-layer capacitors that store energy by nanoscale charge separation at the electrode-electrolyte interface (i.e., “supercapacitors”).Type: GrantFiled: July 10, 2014Date of Patent: October 20, 2015Assignees: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGY, THE UNITED STATES OF AMERICA, as represented by the Secretary of the ArmyInventors: Woo Young Lee, Linh Le, De Kong, Matthew Henderson Ervin, James L.
