A beverage dispenser includes a nozzle to dispense a beverage. The beverage dispenser further includes a camera to capture an image of the beverage as the beverage is dispensed from the nozzle. The camera has a field of view that includes the beverage. The beverage dispenser further includes a light source that illuminates the field of view of the camera. The beverage dispenser further includes a computer. The computer analyzes the image of the beverage and determines a characteristic of the beverage.

Seminaphthofluorophore-selenium probes are disclosed. The probes include a seminaphthofluorophore scaffold substituted with at least one diselenide moiety having a formula —Y—C(Q)O—(CH.sub.2).sub.m—Se—Se—(CH.sub.2).sub.n—OR.sup.f, where R.sup.f is hydrogen or C.sub.1-C.sub.3 alkyl, Q is O or S, Y is O or N(R.sup.g) where R.sup.g is H or alkyl, and m and n independently are integers. The probes may be used to detect presence of a thioredoxin reductase.

A method of forming a colorimetric sensor includes depositing a first material onto a substrate, providing porous sensing particles, wherein the sensing particles comprise sensing species dispersed into a porous host structure, and embedding the porous sensing particles onto a surface of the deposited first material, the first material attaching the sensing particles to the substrate with at least a portion of the sensing particles is exposed to an ambient environment.

A wearable pollutant indicator, methods of making and using same. The indicator includes a polymeric film substrate having a first side and a second side, an adhesive disposed on the first side of the substrate, and a readily understood user interface disposed on the second side of the substrate, wherein the user interface comprises a qualitative indicator of the accumulated exposure to incident airborne particulate pollution as sensed through the reaction of the transition metal oxides therein.

A rope ring with a wear indicator. The typical ring is toroidal in shape. The wear indicator is a pair of opposed annular grooves in the side walls optionally spaced from the hole edge. As the ring wears, the hole diameter increases at points along either hole edge. In one method, maximum wear occurs when the hole wall edges form one or more indentations in either groove. In another method, maximum wear occurs when either groove is severed at one or more points on the groove. Optionally, the grooves are filled with a coloring agent to provide greater visibility to the wear indicator.

Provided are a measurement sample diluent that enables the measurement of the proportion of HbA1c in the total Hb molecules in a measurement sample (HbA1c (%)), with high sensitivity, high accuracy, and high correlation with HPLC without being affected by the length of time required to mix a measurement sample with the measurement sample diluent and to drop the mixture onto an immunochromatographic specimen for measuring HbA1c; and a kit containing the measurement sample diluent. The present invention relates to a measurement sample diluent for immunochromatography for quantifying the proportion of hemoglobin A1c in the total hemoglobin molecules in a measurement sample (hemoglobin A1c (%)); and the measurement sample diluent is an aqueous solution that contains a non-ionic surfactant, an anionic surfactant, and a buffer.
