摘要： An air data probe includes a probe body and an air data sensing port disposed in the probe body. The probe body includes a barrel region, a tapered head region extending forward from the barrel region, and a tip at a forward-most end of the tapered head region. The air data sensing port is disposed in the probe body at a port location aft of the tip. The probe body has a turbulence-producing geometry originating at the tip that produces a turbulent boundary layer of airflow that extends from the tip to the port location.

摘要： A method for generating a psychoacoustic model from an audio signal transforms a block of samples of an audio signal into a frequency spectrum comprising frequency components. From this frequency spectrum, it derives group masking energies. These group masking energies each correspond to a group of neighboring frequency components in the frequency spectrum. For a group of frequency components, the method allocates the group masking energy to the frequency components in the group in proportion to energy of the frequency components within the group to provide adapted mask energies for the frequency components within the group, the adapted mask energies providing masking thresholds for the psychoacoustic model of the audio signal.

摘要： Disclosed is a method of processing a periodic voltage signal, called the input signal, relating to the pressure existing in a combustion chamber of a cylinder of an internal combustion engine. The method includes a step (E6) of determining a second instant of unlocking of the base signal during a second peak phase, a step (E7) of determining a second instant of locking, which is subsequent to the second instant of unlocking and for which the input signal is in the plateau phase consecutive to the second peak phase, and a step (E8) of generating a base signal between the second instant of unlocking and the second instant of locking on the basis of a slope value of a straight line determined during a first peak phase between a first instant of unlocking and a first instant of locking.

摘要： A pressure gauge of which the presence or absence of a measurement error can be easily checked is provided. A pressure gauge includes: a piston; a first conversion mechanism converting a linear motion of the piston against an elastic force of a spring into a rotating motion about a first rotation shaft, the linear motion being caused by the pressure transmitted from a target to be measured; an index that is fixed to one end side of the first rotation shaft; a dial; momentum detecting means for detecting momentum indicating an amount of movement of the piston; and a pressure sensor measuring a pressure value or the pressure acting on the internal space of the cylinder. Determining means determines whether a difference between a first measurement value and a second measurement value exceeds a predetermined value, the first measurement, value being estimated from the momentum detected toy the momentum detecting means, the second measurement value being measured by the pressure sensor. Notifying means notifies a user if the difference between the first measurement value and the second measurement value exceeds the predetermined value.

摘要： A method to correct a current measurement of pressure of a gas stream delivered during a mission by a sensor in the engine. The method includes: estimating a drift error affecting the sensor on the basis of a difference existing between: (1) a calibration measurement of the pressure of the gas stream as delivered by the sensor in the engine, and (2) an atmospheric pressure measurement delivered by a sensor of the aircraft presenting accuracy greater than that of the sensor in the engine; these measurements being performed while the sensor in the engine and the sensor of the aircraft are subjected to same surrounding atmospheric pressure; and subtracting the estimated drift error from the current measurement.
