    摘要： A ratiometric method for using optical sensors is provided to measure dissolved oxygen in a fluid sample. The sensor is formulated so as to contain an oxygen permeable membrane of a cured perfluorinated urethane polymer and, incorporated therein, an oxygen-sensitive indicator component and a reference dye component. The emission spectrum from the indicator component is calibrated by comparison with that of the reference dye, which is substantially less sensitive to oxygen-quenching and which has a photodecomposition rate similar to the indicator component. Methods for making and using the membrane and sensor are provided as well.

    摘要： A simultaneous dual excitation/single emission ratiometric method using fiber optic sensors is provided for detecting or measuring a parameter of interest in a sample, including pH, concentration of gases such as CO.sub.2, and the like. The method involves simultaneously providing modulated optical light corresponding to first and second regions of an indicator species' absorption or excitation spectrum, detecting modulated emission signals from the indicator species, demodulating the emission signals, calculating the apparent quantity of analyte present in the sample from the indicator emission signals and correcting the apparent quantity of analyte present for variations resulting from external factors, by determining the ratio of the demodulated indicator emission signals. An apparatus is provided for performing the method as well.

    摘要： A system, including: a sensor that monitors containers as the containers move along a production line; a rejection device; a controller communicatively connected to the sensor and the rejection device, wherein the controller is programmed to determine whether a container is associated with a match condition in response to a signal received from the sensor, the match condition reflecting that the container is associated with predetermined properties or characteristics, in response to a match condition, determine a pass result, and otherwise determine a fail result, determine a velocity of the production line, dynamically determine a correction amount for a reject position, track a position of the container on the production line, and in response to the fail result, outputs a signal to actuate the rejection device that removes the container from the production line based on the velocity of the production line, the dynamically determined correction amount, and the position of the container on the production line.

    摘要： Some embodiments for a fault detection apparatus may include one or more monitors to detect at least three operating states of a sensor, such as pass, fail, and inoperative so as to enable a manufacturing facility to differentiate between situations in which a container does not have the appropriate machine readable label and situations wherein the sensor is actually inoperative. The fail state may be indicative of an object on a conveyor system not matching a predetermined description, identity or characteristic. The pass state may be indicative of an object on a conveyor system matching the predetermined description, identity or characteristic. The inoperative state may be indicative of a sensor output associated with a malfunction in the sensor itself. The fault detection apparatus may also include a fail-to-safe controller configured to detect these operating states.

    摘要： A fiber optic sensing device for measuring a chemical or physiological parameter of a body fluid or tissue is provided. To one end of the fiber is attached a polymer including a plurality of photoactive moieties selected from the group consisting of chromophores and lumophores, the photoactive moieties spaced apart so as to minimize chemical or physical interaction therebetween while optimizing the density of photoactive moieties. In one embodiment, a polymer chain is covalently bound to photoactive moieties through functional groups such as esters, amides, or the like. In a second embodiment, a polymer chain is inherently fluorescent and is formed from at least one monomeric unit. These devices are particularly useful as pH and oxygen sensors.
