A device for detecting the presence of pollen in the air, including a measuring chamber isolated from external light, an arrangement configured to drive an air flow through the measuring chamber, and a light source emitting a light beam in a direction of propagation through the air flow, into the measuring chamber. The device includes at least four photosensitive sensors configured to measure the luminous flux diffused by the illuminated air flow, in four different directions, a clock, at least two meteorological sensors, and at least one computer capable of determining the nature of a pollen particle present in the air from the data measured by the photosensitive sensors, the clock and the meteorological sensors.

Disclosed is a method for controlling a hybrid vehicle power train, including a thermal drive chain and an electric drive chain, the electric drive chain including a traction battery, a voltage modulator, an inverter, first and second electrical machines. The voltage modulator is designed to modulate a supply voltage of an electric current from the traction battery to the first and second electrical machines. The method includes: a step of analytically calculating an optimal supply voltage using a mathematical expression that corresponds to the resolution of an equation expressed as ∂ P b a t ∂ U e = 0 , where Ue is the supply voltage, Pbat is the electrical power supplied by the traction battery, and where the electrical power supplied by the traction battery is expressed as a quadratic function of the supply voltage; and a step of controlling the voltage modulator in such a way that it outputs the optimal supply voltage.

A mixing tube with multiple shapes is provided, allowing additional injection of gas in order to keep the flow detached from the second shape in an ascent phase and to bring about, in a descent phase, a controlled detachment as a result of the change of slope between the two shapes. A propulsion nozzle for an engine of a spacecraft or aircraft is provided including such a mixing tube and a method for controlling the speed transition of the propulsion gases in such a nozzle in accordance with the altitude. Also, a method is provided for vectorising the thrust in such a nozzle by radial and asymmetrical injection of gas and a control method which prevents re-attachment of the jet to the second shape of such a propulsion nozzle for an engine of a spacecraft when it is in the take-off or landing phase.

摘要:
An electrochemical capacitor includes a first electrode connected to a positive terminal of a power source during the charge of the electrochemical capacitor and a second electrode connected to a negative terminal of a power source during the charge of the electrochemical capacitor. The first and the second electrodes each have a carbon material. The electrochemical capacitor further includes a porous separator to separate the first and second electrodes and to be impregnated with an almost neutral aqueous electrolyte situated between the two electrodes. The neutral aqueous electrolyte has a salt formed by a metallic cation and an anion.

摘要:
Disclosed is a method for calculating a control setpoint of a hybrid powertrain of a motor vehicle, the hybrid powertrain including an electric motor and an internal combustion engine (ICE) that is equipped with a gearbox and that is supplied with fuel. The method includes: acquiring a value relative to a power requested at the vehicle's drive wheels; and determining the contribution of the electric motor and the ICE in order to satisfy the request for power at the drive wheels. The determination step involves calculating a triplet of three values, one value relating to the electromechanical power that the electric motor must provide, one value relating to the thermomechanical power that the ICE must provide and one value relating to the ratio that needs to be engaged in the gearbox, this triplet minimising the fuel consumption of the ICE and the current consumption of the electric motor.
