Memory Error Detection
Systems and methods are provided for detecting and correcting address errors in a memory system. In the memory system, a memory device generates an error-detection code based on an address transmitted via an address bus and transmits the error-detection code to a memory controller. The memory controller transmits an error indication to the memory device in response to the error-detection code. The error indication causes the memory device to remove the received address and prevent a memory operation
MAINTAINING CORE DUMP PRIVACY DURING APPLICATION FAULT HANDLING
Maintaining core dump privacy during application fault handling. A core memory dump is received for an application from a runtime engine. Areas of the core memory dump are analyzed to identify structural data in the form of internal structures of the runtime engine. The identified structural data is retained in a modified core memory dump, and remaining non-structural data in the areas of the core memory dump is processed to ensure it is not readable by unauthorized entities in the modified core memory dump. The modified core memory dump is outputted for fault analysis.
Pivot controller
An improved pivot controller is described that solves existing deficiencies in pivot controllers. Specifically, a pivot controller that can interface with either a hot or neutral safety, detect failed contactors and relays, and verify the safety control circuit is described. The described improved pivot controller permits easier installation, safer operation, and faster diagnostics than existing pivot controllers.
Plant control device, plant control method, and recording medium

Abnormality detection system, abnormality detection method, abnormality detection program, and method for generating learned model
A method and system that efficiently selects sensors without requiring advanced expertise or extensive experience even in a case of new machines and unknown failures. An abnormality detection system includes a storage unit for storing a latent variable model and a joint probability model, an acquisition unit for acquiring sensor data that is output by a sensor, a measurement unit for measuring the probability of the sensor data acquired by the acquisition unit based on the latent variable model and the joint probability model stored by the storage unit, a determination unit for determining whether the sensor data is normal or abnormal based on the probability of the sensor data measured by the measurement unit, and a learning unit for learning the latent variable model and the joint probability model based on the sensor data output by the sensor.
Systems and methods for predictive system failure monitoring
Systems, methods, and computer-readable storage media configured to predict future system failures are disclosed. Performance metrics (e.g., key performance indicators (KPIs)) of a system may be monitored and machine learning techniques may utilize a trained model to evaluate the performance metrics and identify trends in the performance metrics indicative of future failures of the monitored system. The predicted future failures may be identified based on combinations of different performance metrics and the impact that the performance metric trends of the group of different performance metrics will have on the system in the future. Upon predicting that a system failure will occur, operations to mitigate the failure may be initiated. The disclosed embodiments may improve overall performance of monitored systems by: increasing system uptimes (i.e., availability); helping systems administrators maintain the monitored systems in a healthy state; and ensuring the functionality those systems provide is readily available to system users.
Forced device reinitialization without mandatory restart
Various embodiments herein each include at least one of systems, devices, methods, and software for forced device reinitialization without mandatory restart. One method embodiment includes receiving, by a first device, a first data communication and responding, by the first device, to the first data communication with a second data communication identifying a state of the first device as a reset state. This embodiment further includes receiving, by the first device in response to the second data communication, a third data communication including data to alter the state of the first device from the reset state to a programmed state. Such embodiments may then implement the data of the third data communication to place the first device in the programmed state.
