Publication number: 20200132657Abstract: A method of analyzing a rock sample includes analyzing one or more large-area, low-resolution micrographs to identify areas requiring higher-resolution imaging, and selecting one or more analysis regions from the areas requiring higher-resolution imaging. Multi-spectral imaging is used on the one or more analysis regions to obtain one or more high-resolution, multi-spectral images, and one or more features of the rock sample are identified from the corresponding one or more high-resolution, multi-spectral images. The method further includes upscaling the one or more high-resolution, multi-spectral images and thereby geo-locating the features of the rock sample to key regions of the rock sample.Type: ApplicationFiled: August 27, 2019Publication date: April 30, 2020Inventors: Hubert E.

Publication number: 20200132660Abstract: A method for fast detecting pavement asphalt and early warning based on infrared spectrum data. Infrared spectrum data of standard sample asphalt is collected by adopting an infrared spectrometer, to establish an infrared spectrum database of standard sample asphalt. The infrared spectrum database of the standard sample asphalt and basic asphalt information is introduced into a cloud server through a spectrum input module. A database-matching calculation method and a threshold value is set through a spectrum-matching analysis module. The infrared spectrum data and engineering information of the tested asphalt is collected and uploaded to a cloud platform for storage. A matching calculation between the uploaded data and the spectrograms in the infrared spectrum database of the standard sample asphalt through the cloud server is conducted. An asphalt matching result is outputted to a display terminal. An early-warning message is pushed by the cloud server if a test result is not-match.Type: ApplicationFiled: October 30, 2018Publication date: April 30, 2020Inventors: Xiaomin Li, Jingzhuo Zhao, Dingbang Wei, Guohong Zhang, Fukui Zhang, Qiang Wei, Hui Wang, Qingxia Cao, Min Ding

Publication number: 20200132662Abstract: A system and method for augmenting or adding to the information used by an in-vitro diagnostic or other diagnostic device to generate results of a test is disclosed. A diagnostic device is capable of generating test results based on a sample, such as a sample provided by a patient, and is also capable of receiving additional information to enhance the results providable by the device. For example, an in-vitro diagnostic device is configured to read a lateral flow assay test, and is configured to receive additional diagnostic, network, test identification, or environmental information over a network. Using both the result of the diagnostic test and the additional information, the disclosed device provides more thorough, accurate, and reliable diagnostic information. The results generated by the device may be communicated to an appropriate remote device to enhance the results obtainable by such tests.Type: ApplicationFiled: October 28, 2019Publication date: April 30, 2020Inventors: Stephan Hengstler, Tong Xie

Publication number: 20200132663Abstract: Nanopore flow cells and methods of manufacturing thereof are provided herein. In one embodiment a method of forming a flow cell includes forming a multi-layer stack on a first substrate, e.g., a monocrystalline silicon substrate, before transferring the multi-layer stack to a second substrate, e.g., a glass substrate. Here, the multi-layer stack features a membrane layer, having a first opening formed therethrough, where the membrane layer is disposed on the first substrate, and a material layer is disposed on the membrane layer. The method further includes patterning the second substrate to form a second opening therein and bonding the patterned surface of the second substrate to a surface of the multi-layer stack. The method further includes thinning the first substrate and thinning the second substrate. Here, the second substrate is thinned to where the second opening is disposed therethrough.Type: ApplicationFiled: September 17, 2019Publication date: April 30, 2020Inventors: Joseph R.
