Abstract: A method to monitor the health status of a rolling bearing of a machinery, including a first acquiring step of a rotation speed value of a shaft coupled to the rolling bearing, a second acquiring step of a first signal generated by a vibration sensor located on the machinery in a position distant from the rolling bearing, and a first calculating step of a variation of the shaft rotation speed value during a predetermined time interval, and if the calculated variation of the rotation speed falls within a predetermined variation interval, performing a first filtering step of the first signal with a first algorithm based on a vibration produced by parts of the machinery different from the bearing at the rotation speed value, so as to obtain a second signal representative of a bearing health status.

Abstract: A controller includes a processor and memory. The memory stores instructions that, when executed, are configured to cause the processor to receive measurements pertaining to a measured operation parameter of at least a portion of a turbine system. The instructions are also configured to cause the processor to generate a customized model for the at least the portion of the turbine system. Moreover, the instructions are configured to cause the processor to estimate an estimated value using the received measurements. The estimated value pertains to a parameter of the turbine system. Furthermore, the instructions are configured to cause the processor to using the customized model, reduce or remove at least some environmental conditions from a corrected estimated value derived from the estimated value.

Abstract: A system and method for remotely monitoring and diagnosing a device is disclosed. Data related to the device is obtained at a first network. The obtained data is encrypted to generate an encrypted code at the first network. A copy of the encrypted code is obtained at a second network that is separated from the first network via a non-network medium such as an air gap. The copy of the encrypted code is decoded to obtain the data related to the device at the second network. The data is used at the second network to monitor and diagnose the device at the second network.
