Patent number: 11782058Abstract: A diagnostic test system includes a housing, a reader, and a data analyzer. The housing includes a port constructed and arranged to receive a test strip that includes a flow path for a fluid sample, a sample receiving zone couple to the flow path, a label that specifically binds a target analyte, a detection zone coupled to the flow path and comprising a test region exposed for optical inspection and having an immobilized test reagent that specifically binds the target analyte, and at least one reference feature. The reader is operable to obtain light intensity measurements from exposed regions of the test strip when the test strip is loaded in the port.Type: GrantFiled: January 25, 2019Date of Patent: October 10, 2023Assignee: ALVERIX, INC.Inventors: Patrick T. Petruno, John Francis Petrilla, Michael J. Brosnan, Rong Zhou, Daniel B. Roitman, Bo U. Curry

Patent number: 11733169Abstract: A multiple analyte detection system includes a carrier having reagents disposed thereat, with each of the reagents capable of optically changing in response to exposure to a respective analyte. The system further includes a photodetector positioned to collectively detect light interacted with each of the reagents, a processor to determine a presence or an absence of each of the analytes in response to the light collectively-detected, and an indicator to provide an indication of the presence or the absence of each of the analytes. A method of detecting multiple analytes includes exposing reagents capable of optically changing in response to exposure to a respective analyte to a sample. The method further includes collectively detecting light interacted with each of the reagents, determining a presence or an absence of each of the analytes in response to the light collectively detected, and indicating the presence or the absence of each of the analytes determined.Type: GrantFiled: December 14, 2020Date of Patent: August 22, 2023Assignee: ALVERIX, INC.Inventors: Ian Hardcastle, Carol T. Schembri, John Francis Petrilla, Rene B. Helbing, Daniel B. Roitman

Publication number: 20090257745Abstract: An eye mask is provided that is defined at least partially in terms of absolute, or non-relative, optical power level values. In essence, the eye mask of the invention is a hybrid of the traditional eye mask in that the eye mask of the invention includes power level values on the optical power axis that are based on the minimum OMA set forth in the applicable standard or data sheet specification rather than on measured power level values obtained from the part being tested. Using the hybrid eye mask of the invention obviates the need to perform at least some of the tests often used to measure transmitter attributes. In addition, using the hybrid eye mask of the invention reduces the possibility that a transmitter may fail the eye mask test even though the transmitter operates satisfactorily.Type: ApplicationFiled: April 14, 2008Publication date: October 15, 2009Applicant: Avago Technologies Fiber IP Pte. Ltd.Inventors: John Francis Petrilla, Rudy L. Prater
