Abstract: An identifier made using a silicon film. The silicon film has a varying optical index of refraction. The varying optical index of refraction reflects one or more spectral peaks when illuminated with light. The one or more spectral peaks includes a reference peak. The silicon film is fragmented and then oxidized.

Abstract: A system for packaging an item with an identifier comprises an identifier adder, a labeler, and a packager. The identifier adder adds one or more types of silica-based tags to an item, wherein each type of silica-based tag has a first signature readable using an optical spectroscopic reader. A label is generated based at least in part on reading the one or more types of silica-based tags of the item using the optical spectroscopic reader. The label includes goods info. The packager includes the label on a package, and wherein the packager includes the item in the package.

Abstract: A system for identifying tags comprises an imaging sensor and a processor. The imaging sensor acquires image(s) of tag(s) from light reflected from the tag(s) on a tagged item. The processor is configured to: receive the image(s) and a library of tag types; using the image(s), determine feature metrics using a machine learning algorithm and is based on an image processing, manipulation, and/or correction; using the feature metrics and the library of tag types, determine a tag type of the tag(s) in the image(s) based on a local maxima determination, a bounding box generation, a tag candidate patch extraction, a tag candidate segmentation, a tag candidate feature metric determination, and/or a comparison to a model; determine a confidence level of the tag type; and in response to the confidence level being above a threshold level, provide the tag type determined.

Abstract: A system detects an analyte suspected of being present in a sample. The reader reads an optical tag on a substrate, which is configured to immobilize the tag on a substrate surface. The optical tag is bound to a probe and includes a plurality of pores that create an effective index of refraction. The plurality of pores and a thickness of the tag are selected for a reflectance property. The substrate is configured to contact a sample suspected of comprising an analyte. The probe is capable of binding specifically to the analyte. The reader is configured to expose the tag to light to generate a sample spectral signature that is a function of the effective index of refraction, the thickness of the optical tag, and whether the analyte is coupled to the probe. The sample spectral signature is compared to a reference to detect the analyte in the sample.

Abstract: A system for determining a calibrated spectral measurement includes a tunable Fabry-Perot etalon, a detector, and a processor. The tunable Fabry-Perot etalon has a settable gap. The detector measures light intensity. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements. For a calibration measurement, a settable gap is selected and a set of input monochromatic source wavelengths is used to measure responses at a detector after transmission through the Fabry-Perot etalon. Each input monochromatic source wavelength is also measured using a radiometer to scale detector measurements.

Abstract: This disclosure enables high-productivity fabrication of porous semiconductor layers (made of single layer or multi-layer porous semiconductors such as porous silicon, comprising single porosity or multi-porosity layers). Some applications include fabrication of MEMS separation and sacrificial layers for die detachment and MEMS device fabrication, membrane formation and shallow trench isolation (STI) porous silicon (using porous silicon formation with an optimal porosity and its subsequent oxidation). Further, this disclosure is applicable to the general fields of photovoltaics, MEMS, including sensors and actuators, stand-alone, or integrated with integrated semiconductor microelectronics, semiconductor microelectronics chips and optoelectronics.
