Abstract: A method of monitoring oil level in a tank of an aircraft engine, including: for at least two predetermined operating stages of the engine, during at least one mission of the aircraft: obtaining a plurality of measurements of an oil level of the tank, each measurement being associated with an oil temperature and with an engine speed of rotation, and selecting measurements representative of oil level variations and associated with oil temperatures that are close to a reference temperature and with engine speeds of rotation that are close to a reference speed of rotation; aggregating the measurements selected over the operating stages and during the at least one mission of the aircraft; and comparing the aggregated measurements with reference data to identify abnormal oil consumption of the engine.

Abstract: A method of controlling a hybrid drive-train of a vehicle having a combustion engine with a driveshaft, a transmission with an input shaft and an output shaft that drives a transfer box. An electric machine has a rotor that is connected to the transmission input shaft. A separator clutch is arranged between the engine driveshaft and the transmission input shaft. For coupling of the engine, the engine is first accelerated, with a rotational speed regulation, toward a target speed until a reference speed is reached or exceeded while the clutch remains disengaged, then, with continuous speed regulation, the engine is adjusted to a corrected target speed while the clutch is engaged until a target torque is obtained, then, with torque control, the engine is adjusted to the target torque while the clutch, with differential rotational speed regulation, is regulated to a target speed difference, and finally the clutch is engaged.

Abstract: A method and apparatus for carrying out a set of vehicle inspections including, but not limited to, wheel alignment measurement, brake testing, tire tread depth measurement, tire pressure monitoring, vehicle battery testing, and a review of vehicle diagnostic trouble codes in an efficient manner using a multi-function vehicle service system and a single vehicle service bay or inspection lane. Results of the vehicle inspections are incorporated into customized reports generated for a customer or for a technician, and which may be utilized to obtain approval from the customer to conduct necessary repairs and/or provide beneficial vehicle services.
