Abstract: An in-situ averaging combustion analyzer includes a housing and a probe coupled to the housing at a proximal end. The probe has a distal end configured to extend into a flue and contains a zirconia-based oxygen sensing cell proximate the distal end. Electronics are disposed in the housing and are coupled to the zirconia-based oxygen sensing cell. The electronics are configured to measure an electrical characteristic of the zirconia-based oxygen sensing cell and calculate an oxygen concentration value. An averaging conduit is disposed about the probe and has a plurality of inlets spaced at different distances from the distal end of the probe. The averaging conduit has at least one outlet positioned between the distal end and the proximal end of the probe. The electronics are configured to provide an average oxygen concentration output based on the calculated oxygen concentration value.

Abstract: Particular embodiments described herein provide for an electronic device that can be configured to acquire a string, convert the string to an image, compare the image of the string to an image of a test string, and determine a similarity score. The similarity score provides an indication as to how visually similar the string is to the test string. In an example, the string is part of an attempt to spoof the test string.

Abstract: A method includes communicatively coupling a user device to a field device in an industrial control system in order to configure and provision the field device. The method also includes selecting an operating mode of the user device. The method further includes, in response to selecting a first operating mode, providing configuration data from the user device to the field device in order to configure the field device. In addition, the method includes, in response to selecting a second operating mode, providing provisioning data from the user device to the field device in order to provision the field device onto a wireless network. Providing the configuration data and the provisioning data could include communicating the provisioning data and the configuration data to the field device through an out-of-band communication interface. The out-of-band communication interface may include a direct wired interface or infrared interface.

Abstract: An environmentally sealed electronics assembly. The assembly includes a flexible envelope surrounding the active electronics board. The electronics board is insertable into the envelope and with subsequent sealing provides a reenterable but environmentally sealed active electronics package. Methods of manufacturing the assembly are also described.

Abstract: An optical fiber water sensor includes a mandrel having a convex or concave shape adjacent to an optical fiber which is adjacent to a water swellable material held in a reservoir. Upon coming in contact with water, the material swells and deforms a section of the optical fiber about a contour defined by the mandrel thus attenuating a signal propagating through the fiber which is detected by an optical detector to indicate the presence of water.
