Publication number: 20240116047Abstract: Liquid reservoirs, cartridge assemblies and related systems and methods are disclosed. An example implementation includes an apparatus that includes a body, a cover, and a lid assembly. The body includes a top surface and a storage chamber having an opening at the top surface. The cover covers or is positioned within the opening of the storage chamber. The lid assembly is coupled to the top surface and covers the opening of the storage chamber. The top surface and the first portion define a plenum. The cover is at least one of piercable, breakable, or movable to allow the storage chamber to be fluidly coupled to the plenum without venting the plenum to atmosphere.Type: ApplicationFiled: September 29, 2023Publication date: April 11, 2024Inventors: Panteleimon Athanasiou, Beng Keong Ang, Justin Davidson, Norman Khoo, Heng Kuang Cheng, Hao Yu, Zhenning Cao

Patent number: 10830781Abstract: Detection apparatus includes a microfluorometer having an objective, an excitation radiation source, and a detector. The detection apparatus also includes a fluidic system for delivering reagents from a reagent cartridge to a flow cell. The fluidic system includes a manifold body having a plurality of fluidic channels configured for fluid communication between the reagent cartridge and the flow cell. The fluidic system also includes a plurality of reagent sippers. The fluidic system also includes a valve configured to mediate fluid between reagent reservoirs and the flow cell. The detection apparatus also includes a flow cell latch clamp module having a clamp cover for holding the flow cell. The objective is configured to direct excitation radiation from the radiation source to the flow cell and to direct emission from the flow cell to the detector. The microfluorometer is movable to acquire wide-field images of different areas of the flow cell.Type: GrantFiled: March 26, 2018Date of Patent: November 10, 2020Assignees: ILLUMINA, INC., ILLUMINA SINGAPORE PTE LTDInventors: Beng Keong Ang, Heng Kuang Cheng, John M. Beierle, Bradley Kent Drews, David Kaplan

Patent number: 8783983Abstract: A printer is disclosed that has a frame and a chute assembly received within the frame in which the chute assembly is pivotable relative to the frame. The chute assembly includes a lower chute part and an upper chute part. The lower chute part is pivotable about a first axis in which the first axis is fixed relative to the frame. The upper chute part is pivotally coupled to the lower chute part and is pivotable about a second axis that is fixed relative to the lower chute part. The lower chute part and the upper chute part are coupled to one another such that, when the upper chute part pivots about the second axis relative to the lower chute part, the lower chute part automatically pivots about the first axis.Type: GrantFiled: September 6, 2012Date of Patent: July 22, 2014Assignee: Brady Worldwide, Inc.Inventors: Chow Jin Bryan Chng, Heng Kuang Cheng
