  • Publication number: 20240258470
    Abstract: This specification discloses LEDs, pcLEDs, and arrays of LEDs or pcLEDs in which the LEDs or pcLEDs comprise a structured high refractive index coating on a light output surface that improves light extraction from the device through the light output surface. The coating is formed additively instead of by a subtractive process that removes material from the surface, and consequently can avoid the disadvantages associated with subtractive processes.

  • Patent number: 11782058
    Abstract: 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.

  • Patent number: 11733169
    Abstract: 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.

  • Publication number: 20200411728
    Abstract: A light emitting package and method of making the package are described. The package contains an LED bonded to a light converting layer using an adhesive. The adhesive is jet printed, mask sprayed or extruded onto one of the surfaces before bonding. The adhesive has materials in different sections that differ in refractive index, oxygen permeability, and/or heat conductivity. The materials are formed in concentric rings around the adhesive center, islands or lines and are disposed to provide optical lensing or increasing permeability/heat conductivity with decreasing distance from the center. A substantially-reflective optical side coat surrounds the LED, adhesive layer and connecting structure.

  • Publication number: 20200393460
    Abstract: In one aspect, an assay test strip includes a test label that specifically binds a target analyte and a control label that is free of any specific binding affinity for the target analyte and has a different optical characteristic than the test label. In another aspect, an assay test strip includes a test label that specifically binds a target analyte and at least one non-specific-binding label that is free of any specific binding affinity for the target analyte. Systems and methods of reading assay test strips also are described.
