Abstract: A wearable electronic device may alert a wearer as to a presence of either a range of allergens or to specific pollen to which the individual is allergic. As such, the device may warn the user of bioparticles likely to affect them allergenically. The device may include an airflow path. A deterministic lateral displacement (DLD) array may be positioned within the airflow path to capture bioparticles of a particular size. An imaging device may capture images of captured bioparticles. The system may include a database of bioparticles in a range of sizes. The system may be configured to compare the captured bioparticles to the information in the database. A wearer may be alerted if bioparticles potentially allergenically problematic to the person have been found in the captured bioparticles.

Abstract: A conformal coating composition for protecting a metal surface from sulfur related corrosion includes a polymer and metal nanoparticles blended with the polymer. In accordance with some embodiments of the present invention, an apparatus includes an electronic component mounted on a substrate, metal conductors electronically connecting the electronic component, and a polymer conformal coating containing metal nanoparticles overlying the metal conductors. Accordingly, the metal nanoparticle-containing conformal coating is able to protect the metal conductors from corrosion caused by sulfur components (e.g., elemental sulfur, hydrogen sulfide, and/or sulfur oxides) in the air. That is, the metal nanoparticles in the conformal coating react with any corrosion inducing sulfur component in the air and prevent the sulfur component from reacting with the underlying metal conductors.

Abstract: In an example, a method includes obtaining an expected biological sample value at a computing device. The expected biological sample value indicates an expected concentration of a material biologically processed by a courier. The computing device determines whether the measured biological sample value is associated with the courier based on a comparison of the expected biological sample value to the measured biological sample value. The method also includes determining a particular set of operations to be performed at the computing device based on a result of the comparison.
