摘要： A method for determining and characterizing road unevenness of a roadway. Sensor data are generated by at least one wheel speed sensor and/or at least one wheel-individual acceleration sensor of a motor vehicle travelling the roadway. The road unevenness is determined and characterized by an arithmetic unit using the sensor data generated.

摘要： Aspects of this disclosure relate to a torque and angle sensing device. A sensor and a processing circuit are integrated into the device. The sensor is configured to generate a first signal indicative of a first angle and/or speed. The device includes an input contact configured to receive a second reference signal indicative of a second reference angle and/or speed. The processing circuit is configured to generate an indication of torque based on at least the first signal and the second signal. In certain applications, the processing circuit is capable of pre-programming and/or learning and storing the reference information and generating an indication of torque based on the first signal generated internally and the reference information. An output contact of the device can provide the indication of torque. Related systems and methods are also disclosed.

摘要： An assembly is provided for a turbine engine. This turbine engine assembly includes a rotating assembly and a sensor. The rotating assembly is configured to rotate about an axis. The rotating assembly includes an engine shaft, a phonic wheel and a lubricant scoop. The phonic wheel is mounted onto the engine shaft. The phonic wheel includes an outer surface and a plurality of apertures arranged circumferentially about the axis. Each of the apertures projects at least partially radially into the phonic wheel from the outer surface. The lubricant scoop is radially outboard of and axially overlaps the outer surface. The sensor is configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis.

摘要： A detection device is for detecting a passage timing of a turbine blade. This detection device is provided with: a sensor including a magnet and a coil that is disposed at a position subject to magnetic flux generated by the magnet and is configured to detect an induced electromotive force based on a change in the magnetic flux accompanying passage of the turbine blade; and an analyzer configured to detect the passage timing of the turbine blade, on the basis of an integrated signal obtained by integrating a signal based on the induced electromotive force.

摘要： A first converter converts an initial attitude in an Euler angle representation into an initial attitude represented by quaternion. An updating unit updates an attitude represented by quaternion by defining the initial attitude represented by quaternion as an initial value, successively substituting output values of the triaxial gyro sensor. A second converter converts the attitude represented by quaternion into an attitude in the Euler angle representation. An angular speed derivation unit derives an angular speed based on a time-dependent change in the attitude in the Euler angle representation. A controller adjusts a period of time for derivation by an initial attitude derivation unit based on a variance value of the output value of the triaxial acceleration sensor or a variance value of the output value of the triaxial gyro sensor, when the speed is lower than a threshold value.

摘要： A magnetic sensor configured to detect a rotation of an object includes at least one sensor element configured to generate at least one sensor signal based on a magnetic field that is modulated by the rotation of the object; a sensor circuit configured to generate a data transmission signal based on the at least one sensor signal, wherein the data transmission signal comprises a plurality of data transmission blocks; and a memory configured to store transmission block status information indicative of whether or not one of the plurality of data transmission blocks has been triggered for transmission. The sensor circuit is configured to detect an interrupt event that disrupts the transmission of the data transmission signal and avoid a complete loss of a data transmission block due to the detected interrupt event based on the transmission block status information present at a time the interrupt event is detected.

摘要： A position sensor is configured to use a Wiegand wire, position magnet(s) and a reset magnet in which changes in polarization of the Wiegand wire caused by the position magnet(s) can be reset by the reset magnet. The position magnet(s), which can move in relation to the Wiegand wire, can have relatively stronger magnetic flux densities, and the reset magnet, which can be fixed in relation to the Wiegand wire, can have a relatively weaker magnetic flux density. When the position magnet(s) are proximal the Wiegand wire, the relatively stronger position magnet(s) overcome the reset magnet to cause a change in polarization of the Wiegand wire which produces an electrical pulse which can be counted. However, when the position magnet(s) become distal to the Wiegand wire, the relatively weaker reset magnet can reset the polarization of the Wiegand wire to prepare for a next count. As a result, the total number of magnets required in the system can be reduced, and the probability of failing to reset the Wiegand wire can be lowered.
