Patent number: 11975321Abstract: A multi-channel optical detection system includes a base unit adapted to receive a multi-chamber assay cartridge having a plurality of reaction chambers loaded with a sample and an optical detection reagent, and an optical detection unit having a multi-channel optical block having a plurality of detection channels each with an associated light source, and an optic sensor. The optical detection unit is connectable to the base unit so that interrogation ports of the detection channels are optically aligned with optically transparent windows of the reaction chambers of a loaded cartridge, so that upon initialization, light sources are activated to interrogate reaction products in the reaction chambers and detect the optical responses therefrom.Type: GrantFiled: March 27, 2019Date of Patent: May 7, 2024Assignee: Lawrence Livermore National Security, LLCInventors: Lawrence C. Dugan, William J. Benett, Elizabeth K. Wheeler

Publication number: 20230157692Abstract: The present disclosure relates to a fastener applicator including a handle, a first trigger coupled rotatably with respect to the handle, and a second trigger coupled rotatably with respect to the handle. An interlock is disposed with the second trigger and comprises a cam follower engaged in a cam channel that selectively prevents rotation of the second trigger relative to the first trigger depending on a location of the cam follower within the cam channel. The location of the cam follower in the cam channel is set by a position of the first trigger. Methods of operating the various embodiments disclosed are also provided.Type: ApplicationFiled: January 24, 2023Publication date: May 25, 2023Applicant: DATASCOPE CORP.Inventors: William K.
