Abstract: A method and system for gas leak detection can involve analyzing image data of a scene in an industrial plant to identify a presence of a unique gas within the scene based on variations in a refractive index of the unique gas relative to surrounding materials, wherein the image data of the scene can be captured without an artificial background screen. Variations in the refractive index can be compared with typical index contrast imaging profiles to distinguish the unique gas from other substances within the scene. A signal or notification indicating a presence of a leak of the unique gas within or from the industrial plant can be output when the unique gas is distinguished from the other substances within the scene.

Abstract: A computerized system and method that enables identifying the best payment currency for a product or service is disclosed. Payment currencies include cash, reward programs and the unit or currency in which reward programs are denominated, and combinations thereof. A single product search request initiates searches of multiple payment currencies. Availability, discounts, prices, comparable costs, net values and relative values are determined and/or calculated per each payment currency. Comparable cost, relative value, or other criteria, may be used to determine the best payment method, that is, the lowest cost in a common currency, such as cash. Determination of the best payment currency is accomplished in “real-time” and has an advantage of leveraging quantitative and qualitative analysis in its determination. In addition, the search may be personalized by adding information unique to each user.
