Abstract: A rotating direction and rotating speed sensing device includes a tested unit, a housing, and a Hall effect sensor disposed in the housing. The tested unit includes an output shaft, and a toothed disk sleeved on and driven by the output shaft. The Hall effect sensor positionally corresponds to the toothed disk for detecting rotating direction and rotating speed, and includes three Hall effect sensing elements spaced apart along a first straight line, and a first pin and a second pin respectively outputting a first signal and a second signal when the toothed disk rotates. The first straight line cooperates with a tangential direction of the toothed disk to form an included angle that ranges in a predetermined angle range, such that a phase shift between the first signal and the second signal ranges from 45 degrees to 135 degrees when the toothed disk rotates.

Abstract: A stationary system is for measuring the surface velocity of a fluid flowing in a river, an open channel or an underground pipe. The system includes a non-invasive device measuring the surface velocity of the fluid, and a wind speed and direction measuring device to validate and/or to correct the measurements taken by the non-invasive device in order to take into account the effect of the wind on the surface velocity of the fluid. A method for validates and/or corrects the measurements carried out by the non-invasive device as a function of the wind speed and direction.

Abstract: A device (17) for detecting the direction of rotation of a rotor for a magnetic bearing includes comparing means (100), first determining means (105), and second determining means (107). The comparing means (100) compares the speed of rotation of the rotor with a predefined speed threshold (Se). The first determining means (105) determines the speed of rotation gradient of the rotor. The second determining means (107) determines the direction of rotation of the rotor from the result of the comparison of the speed of rotation of the rotor with the predefined speed threshold (Se) and the value of the determined parameter representative of the kinetics of the rotor.

Abstract: A vehicle control device includes a counting unit that counts rotation of wheels by a sensor; and a rotation determination unit that determines the rotation based on a count value of each of the wheels obtained by the counting unit. Based on a movement distance of a vehicle, the movement distance of each of the wheels from rotation detection to the next rotation detection is defined as a rotation detection travel distance of each of the wheels. The rotation determination unit determines a rotation direction of a wheel a second time is a direction opposite to that detected for a first time when rotation detection is not performed even once for a first reference wheel having a rotation detection travel distance equal to or less than a rotation detection travel distance of the first determination target wheel while the rotation of the selected first determination target wheel is detected twice.
