Abstract

A non-invasive measuring device calculates a temperature of a medium in a container or conduit. The device includes at least one first sensor disposed on an exterior surface of the container or conduit and measures a temperature (To) of the exterior surface. The measuring device also includes at least one second sensor disposed on the exterior surface and measures a heat flux (q") moving through a wall of the container or conduit. The measuring device further includes a processor operatively coupled to the first sensor and the second sensor. The processor is configured to receive the temperature (To) measurements and the heat flux (q") measurements from the first sensor and the second sensor and to calculate a temperature of the medium in the container or conduit based on input variables about the container or conduit including radius, thickness and thermal conductivity of the material of the container or conduit.

Abstract

A connector to easily and correctly join an electrical component to a printed circuit board is provided. The connector comprises a generally C-shaped electrically conductive element that provides for connection alternatively to the positive and negative terminals of a device depending on the orientation of the connector. In this way, one connector is made that can be used to alternatively satisfy connection to both positive and negative terminals and thereby simplify the construction of the element. Because of the shapes of the ends of the connector, a device can only be plugged in one way. The connector can be made from a single sheet of electrically conductive material bent generally into a "C" shape, with specific tabs and cuts made therein. The connector includes a tab that allows for quick and automated connection to a printed circuit board, and an element to prevent connectors from interlocking while in a loose and unconnected state as, during manufacturing, plating, or storage, allowing them to be added to a board using automated procedures for quick, accurate and low cost construction.
