Patent number: 11802869Abstract: Certain aspects relate to systems and usage techniques for modular lateral flow assay reader devices that can receive a number of different modules having a barcode scanning input device and optional network connectivity capabilities. A barcode scanning module can provide a simple input method that reduces errors compared to manual data entry. A network connectivity module can enable transmission of test results over a public network for standardizing, tracking and electronically connecting test results from assay reader devices located throughout a network. Such devices can programmatically implement a simplified workflow whereby pressing a single button readies the device for imaging, analyzing, and data storage/transmission and, in some implementations, configures the device to operate in one of a plurality of device operation modes.Type: GrantFiled: July 22, 2022Date of Patent: October 31, 2023Assignee: Becton, Dickinson and CompanyInventors: Tong Xie, Stephan Hengstler, Vincent C.

Publication number: 20220187214Abstract: Low-cost assay test strip readers are disclosed. Such readers enable creation of profiles of analyte reactions detected on an assay test strip utilizing a simple detector fixedly mounted to a body of the reader. The detector may be a single detector, such as a photodetector, which detects an optical signal at a single point. The assay test strip is inserted and/or removed from the test strip reader and the detector detects the optical elements of the strip during such insertion and/or removal. The movement of the test strip with respect to the body enables the detector to scan a length of the test strip, such that a one-dimensional profile of the optical signals can be generated. The reader may convert the detected profile into a displayable indication of analyte concentrations for diagnostic purposes. Moving the test strip relative to an array of detectors enables creation of a two-dimensional profile.Type: ApplicationFiled: December 20, 2021Publication date: June 16, 2022Inventors: Tong Xie, Benny Wing Hung Lai

Patent number: 7643576Abstract: A data-signal-recovery circuit includes a flip-flop and a controller. The flip-flop has an adjustable sampling threshold, and, in response to a sampling clock, is operable to generate a recovered digital signal having a first level if an input data signal is above the threshold and having a second level if the input data signal is below the threshold. The controller is operable to adjust the threshold and phase shift of the sampling clock. Because the flip-flop has an adjustable sampling threshold, one can calibrate the flip-flop to the characteristics of the eye pattern at the flip-flop's input node.Type: GrantFiled: May 18, 2004Date of Patent: January 5, 2010Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Benny Wing Hung Lai, Allan Liu

Patent number: 7580452Abstract: A dynamic comparator system includes a dynamic comparator, a feedback filter, and a summer. The dynamic comparator is configured with a comparison signal having an initial state. The dynamic comparator is further configured to receive an input signal and to generate an output signal. The feedback filter is configured to receive the output signal from the dynamic comparator and to generate a filter response signal therefrom. The summer is configured to receive the filter response signal from the feedback filter, to receive the input signal, and to generate a sum signal combining the filter response signal and the input signal. The dynamic comparator compares the input signal to the initial state of the comparison signal, and based on the comparison, optionally adjusts the state of the comparison signal.Type: GrantFiled: November 17, 2005Date of Patent: August 25, 2009Assignee: Avago Technologies General IP (Singapore) Pte.
