Abstract: The present invention generally relates to assigning and reporting the cleanliness of objects and areas, and particularly relates to utilization of object and area cleanliness states as determined by the opposing processes of cleaning and dirtying detected through various methods to provide an indication of the state of cleanliness potentially utilized to alter the process of cleaning and/or dirtying to reach a desired state of cleanliness. Detection of the cleaning and dirtying operations can be performed automatically through image processing and behavior detection of still images/video indicating the activity taking place in the area of interest and time. The state of cleanliness can then be reported to interested parties as textual reports and/or augmented reality overlays on still images/video.

Abstract: Methods, systems, computer-readable media, and apparatuses for providing service to access nodes are presented. In some embodiments, a computing device may generate a geographical coverage map comprising a plurality of wireless access nodes respectively at a plurality of geographic locations and a wireless coverage range for each wireless access node. The computing device may receive from at least one wireless access node of the plurality of wireless access nodes an indication that the at least one wireless access node detected a first wireless access node of the plurality of wireless access nodes. The computing device may refine a first coverage range of the first wireless access node based on a respective geographic location of the at least one wireless access node. In some embodiments, a first wireless access node may receive and forward join emergency mesh (JEM) messages to establish a wireless network.

Abstract: A technique for automated temperature monitoring relies on subject recognition in combination with contactless measurement of subject temperature at one or more measurement stations, with corresponding use of trend analysis. A multiplicity of advantages flow from the use of subject recognition and corresponding trend analysis, including more reliable detection of anomalous temperatures relative to trendlines determined for individual recognized subjects, with possible compensation for group trends, local environmental factors, variability in measuring equipment, etc.

Abstract: A failed element detection and location system for use in a nuclear reactor, for example, a liquid metal fast breeder reactor (LMFBR), which utilizes a large number of fuel pins in an active core and which circulates a continuous stream of liquid metal heat exchanging fluid such as liquid sodium past the pins is disclosed herein. This system first collects a combined sample of the fluid just as the latter passes through at least a selected group of containers, each housing a plurality of the fuel pins. This combined sample is detected for the presence or absence of a predetermined contaminant, specifically neutrons, resulting from the failure (break) in one or more of the fuel pins. In the event that the contaminant is detected in the combined sample, individual samples of fluid are collected, one at a time, as the fluid just passes through the selected group of containers.

Abstract: A cable handling system for use in an installation such as a nuclear reactor is disclosed herein along with relevant portions of the reactor which, in a preferred embodiment, is a liquid metal fast breeder reactor. The cable handling system provides a specific way of interconnecting certain internal reactor components with certain external components, through an assembly of rotatable plugs. Moreover, this is done without having to disconnect these components from one another during rotation of the plugs and yet without interfering with other reactor components in the vicinity of the rotating plugs and cable handling system.

Abstract: A nuclear reactor including an inner core containing both fuel and blanket assemblies and means for cooling the assemblies by passing liquid coolant, specifically sodium, across and in contact with the latter is disclosed herein. The nuclear reactor also includes a particular technique for distributing the liquid coolant into first and second separate plenums, each of which includes an inlet adapted to receive the coolant. These first and second plenums are maintained in fluid communication with the fuel and blanket assemblies, respectively, whereby to pass received coolant across and in contact with all of the assemblies. In addition, the distribution of the coolant is automatically changed, at least to a limited extent, between these first and second plenum in response to predetermined thermal changes in said assemblies.
