The technique implemented by the time-stamping layer uses autonomous device counters and simple arithmetic to label detected events (e.g., safety switching events) with accurate time-stamps without the need to synchronize clocks of the individual safety input devices and safety relay on the safety circuit. In some embodiments, the time-stamping technique is implemented in a single-wire safety system architecture that yields reliable safety device monitoring without the need for dual redundant signal channels. | 05-26-2016 |
20160161375 | TEXT-MINING APPROACH FOR DIAGNOSTICS AND PROGNOSTICS USING TEMPORAL MULTIDIMENSIONAL SENSOR OBSERVATIONS - A system and method for text-mining to conduct diagnostics and prognostics using temporal multi-dimensional sensor observations is disclosed. A computer device stores historical time-series data for a plurality of systems. The computer device collects current time-series data from one or more sensors of a first system. The computer device compares the current time-series data to the historical time-series data to identify patterns in both the current time-series data and the historical time-series data. The computer device generates a failure likelihood prediction for the first system based on the identified patterns in the current time-series data and the historical time-series data. | 06-09-2016 |

20160190983 | Notification Apparatus Usable With Cooling System or Other System - A notification apparatus is usable with a cooling system of a solar inverter and employs various environmental and operational parameters to calculate a cooling efficiency of the cooling system. The value of the cooling efficiency is employed to determine the potential for cooling system problems. The notification apparatus may employ a software-based model of the cooling system that outputs a predicted cooling efficiency. If the difference between the actual cooling efficiency and the predicted cooling efficiency is within a predetermined tolerance, the notification apparatus can instruct the performance of a relatively less extensive diagnostic operation to be performed on the cooling system at night. If the difference in cooling efficiencies is outside the tolerance, a relatively more extensive diagnostic operation can be performed. A rule-based diagnostic system employs the coolant pressures at the inlet and outlet of a radiator to generate one or more diagnoses of the cooling system. | 06-30-2016 |
