Abstract: A scaffolding system comprising a plurality of elongate structural tubes and a plurality of node members. Each node member has three or more mating portions that each extend along one of three mutually perpendicular axes that pass through the respective node member. End portions of the structural tubes can be releasably secured to the mating portions to provide a framework of vertical columns that extend between pairs of node members and horizontal beams that extend between pairs of node members. The scaffolding system further comprises a plurality of tie members that can each be releasably secured at opposing ends to a node member such that the respective tie member is inclined relative to the vertical columns or the horizontal beams, such that the scaffolding system, when assembled, is capable of supporting structural loads.

Abstract: One exemplary data caching architecture having a data cache operable on one or more of cooperating components of a computing environment to store and retrieve computing environment data is provided. The data cache cooperates with the computing environment components to request computing environment data based on selected conditions and store the data for future use by the computing environment. The architecture further has a data cache logic module providing at least one instruction to the data cache to store, retrieve, and process data.

Abstract: One disclosed method includes retrieving a sensor reading, incrementing a reading change counter and setting a stable reading counter in response to the sensor reading not equaling an immediately previous sensor reading, reporting a sensor reading bouncing error and resetting the reading change counter in response to the reading change counter being greater than or equal to a reading change tolerance, incrementing the stable reading counter in response to the sensor reading equaling the immediately previous sensor reading, resetting the stable reading counter and reading change counter in response to the stable reading counter being greater than or equal to a stable reading tolerance, reporting a state change event and setting the most-recent stable sensor reading equal to the sensor reading in response to the sensor reading not being equal to the most-recent stable sensor reading, and setting the previous sensor reading to the sensor reading.

Abstract: A method comprises determining if a sensor reading has changed, determining, in response to the sensor reading having changed, if the sensor reading is toggling, reporting, in response to the sensor reading toggling, a bouncing sensor-state error, determining, in response to the sensor reading having not changed, if the sensor reading is stable, determining, in response to the sensor reading being stable, if the sensor reading is different from a most-recent stable sensor reading, and reporting, in response to the sensor reading being different from a most-recent stable sensor reading, a sensor state change.
