摘要： Systems, methods and apparatuses of predictive maintenance of automotive transmission of vehicles. For example, the transmission has at least one sensor to measure a temperature in transmission fluid, the torque applied on a shaft of the transmission, a vibration sensor, and/or a microphone. During a period in which the vehicle is assumed to be operating normally, the sensor data generated by the transmission sensor(s) is used to train an artificial neural network to recognize the normal patterns in the sensor data. Subsequently, the trained artificial neural network is used to determine whether the current sensor data from the transmission sensor(s) are abnormal. A maintenance alert can be generated for the vehicle in response to a determination that the operations of the transmission are abnormal according to the artificial neural network and the current sensor data.

摘要： A gear train includes a first gear having teeth meshed with teeth of a second gear. Each tooth of the first gear includes a coast side and a drive side opposed to the coast side. The drive side has a pressure angle that is greater than that of the coast side. The gear train can be part of a powertrain system for a rotorcraft, and can replace a traditional gear train in a retrofit or new build. The first gear is a planet gear and the second gear is a ring gear wherein the planet gear and ring gear are in a planetary gear train configuration.

摘要： A wind park controller and control method for a wind park (10) are described. The wind park comprises a plurality of wind turbines (20) and an Energy Storage System (24) connected to one another by means of a low voltage power network (22, 25), which is in turn coupled to the grid. The controller determines a number of operating parameters of the wind turbine gearbox or drive train, and calculates a gearbox or drive train health metric. This can include a measure of the gearbox lifetime. The controller also determines one or more power characteristics of the wind turbine generator or the point of common coupling (26) to determine a power mismatch indication. Based on the power mismatch indication and said gearbox or drive train health metric, the controller determines a power command for the Energy Storage System and wind turbines based to improve the gearbox health and lifetime.
