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： The present invention makes it possible to, even when a stainless steel is adopted in a diaphragm: prevent the diaphragm and a strain sensor from exfoliating from each other; be hardly susceptible to the influence of temperature in an operating environment; not allow the sensitivity of a pressure sensor to be dominated only by the mechanical characteristic of a material constituting the diaphragm; and increase the degree of freedom in design of members constituting the pressure sensor. A pressure sensor according to the present invention is, in order to solve the above problems, characterized in that: the pressure sensor has a diaphragm deforming by the pressure of a fluid, an elastic body covering the whole surface of the diaphragm and joining to the diaphragm on one side, and a strain sensor being arranged by joining on the other side of the elastic body and on an end side apart from a position corresponding to the center of the diaphragm and detecting the deformation of the elastic body working together with the deformation of the diaphragm as a strain; and the elastic body is formed of a material having a linear expansion coefficient close to the linear expansion coefficient of a material constituting the strain sensor.

摘要： A differential pressure measuring device (10, 50) comprising a housing (18) having two pressure areas (20, 22) which are sealed relative to each other and are separated from each other by a membrane (12, 54). The membrane (12, 54) comprises a pressure plate (14) surrounded by an elastic circumferential area (16) allowing axial movement of the pressure plate (14). An indicator element (24, 56) is permanently connected to the pressure plate (14) and whose position can be evaluated in a non-contact manner by a sensor (34, 58). At least one pair of springs (28, 52) is provided, with one spring (30, 32) each of said pair of springs being located in an allocated pressure area (20, 22). Each spring (30, 32) of said pair of springs (28, 52) exerts an opposing spring force on the pressure plate (14).

摘要： An arrangement and method for providing compensation to a cyclical input signal is disclosed. The arrangement comprises a first detection unit (20) for detecting a first event in a cyclical output signal; a compensation signal generation unit (14) for generating a compensation signal; and a signal combination unit (8) for combining the compensation signal and the cyclical input signal to obtain the cyclical output signal. The compensation signal generation unit (14) is arranged to adjust the compensation signal at an instant which has a determined relationship with the detection of the first event. By adjusting the compensation signal at the right instant in a cycle of the cyclical output signal, the adjustment will not influence the further processing of the cyclical output signal. The method can be used to compensate the offset and sensitivity characteristics of a sensor.

摘要： A system and method are provided to authenticate a voice in a frequency domain. A voice in the time domain is transformed to a signal in the frequency domain. The first harmonic is set to a predetermined frequency and the other harmonic components are equalized. Similarly, the amplitude of the first harmonic is set to a predetermined amplitude, and the harmonic components are also equalized. The voice signal is then filtered. The amplitudes of each of the harmonic components are then digitized into bits to form at least part of a voice ID. In another system and method, a voice is authenticated in a time domain. The initial rise time, initial fall time, second rise time, second fall time and final oscillation time are digitized into bits to form at least part of a voice ID. The voice IDs are used to authenticate a user's voice.
