Publication number: 20240120093Abstract: The present invention provides a novel approach for storing, analyzing, and/or accessing biological data in a cloud computing environment. Sequence data generated by a particular sequencing device may be uploaded to the cloud computing environment during a sequencing run, which reduces the on-site storage needs for the sequence data. Analysis of the data may also be performed in the cloud computing environment, and the instructions for such analysis may be set at the originating sequencing device. The sequence data in the cloud computing environment may be shared according to permissions. Further, the sequence data may be modified or annotated by authorized secondary users.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: Alexander G. Dickinson, Francisco Jose Garcia, Robert C. Kain, Scott D. Kahn, Andrew R. Nelson

Publication number: 20240094178Abstract: In various embodiments, both very high speed and very high sensitivity hydrogen detection is achieved by controlling water vapor concentration over the catalyst used to convert hydrogen in sample gas (e.g., ambient air) to water vapor, to provide a substantially stable water vapor mixing level at a target mixing ratio. The naturally-occurring water vapor in the sample gas, without further steps, typically would vary over time within a wide range (e.g., due to changing atmospheric conditions). By controlling a level of water vapor over the catalyst to be substantially equal to a target mixing ratio that is not too low as to impair response time, and not too high as to impair sensitivity, both very high speed and very high sensitivity can be provided.Type: ApplicationFiled: December 1, 2023Publication date: March 21, 2024Inventors: David D. Nelson, JR., Scott C. Herndon, Joanne H. Shorter, Joseph R. Roscioli, Elizabeth M. Lunny, Richard A. Wehr
