| PURPOSE: To detect the circulation speed and the desired position of a felt accurately by forming the cushion of a pressurization fluid at a part with a different thickness being formed near one side edge of a loop-shaped felt and detecting the pressure of the cushion. CONSTITUTION: A sharp part A with a different thickness from that of another part for reaping a fluff is provided near one side edge of a felt F that moves in a loop. The change part of the felt F passes below at least one of pressure transducers 38a-38d being arranged in side direction. On the other hand, a pressurization air from an air fan 32 is guided to a housing 28 by a nozzle 36 via a pipe 30, and the flow of the fluid collides with the felt F at the immediate upstream of the transducer 38. The transducer 38 detects the change in air between air on the surface of the felt F and air on the part A with a different thickness and detects that a part with a different thickness passes below the transducer 38. The circulation speed of the felt and its desired position can be accurately measured and determined by the detection signal. COPYRIGHT: (C)1991,JPO | ||||||

| PURPOSE:To simplify structure and reduce manufacture cost by arranging a spherical body which is pivoted rotatably and has large inertial efficiency in a spherical hollow body and flowing fluid. CONSTITUTION:When slightly pressurized fluid is supplied into a fluid input pipe 5, this fluid flows along the circumferential surface of the spherical body 4 as shown by an arrow and is then discharged from a fluid output pipe 6. In this case, the fluid flowing through the upper and lower parts in the spherical body 4 is stationary fluid, so the spherical body 4 holds a fixed state continuously. For example, when an automobile of a system mounting a fluid inertia sensor 1 is turned as shown by an arrow A, the fluid input and output pipes 5 and 6 and spherical hollow body 2 rotate, but the spherical body 4 having the large inertial efficiency holds the fixed state. Then, the fluid becomes unbalanced in flow rate between the upper and lower parts in the spherical body 4 to generate a pressure difference. The pressure difference is detected by pressure sensors 7 and 8 and supplied to a comparator 9. This comparator 9 generates an analog output with the level corresponding to the revolving angular speed. | ||||||

| A motion sensor may detect linear and/or angular acceleration and/or angular velocity of a body relative to one axis, two orthogonal axes or three orthogonal axes. Movement of the body or reference structure may be detected relative to one or more spinning rotors. The rotor(s) may be suspended for rotation and/or other movement relative to the reference structure without physical contacting the reference structure. In one embodiment, the rotor(s) may be electrostatically suspended in such a way that movement of the rotor(s) relative to the reference structure may be detected. | ||||||

| An apparatus and method for sensing angular displacement of a rotating object. A reference object is provided that maintains an independent angular reference. An angular displacement of the rotating object may be measured with respect to the reference object. The apparatus may include a turn sensor for measuring directional changes in the heading of the object, an angular compensator, and a servomotor for maintaining the turn sensor in a same angular position. The object may be a vehicle such as a boat, car, train, airplane or any other vehicle. The turn sensor is coupled to the servomotor that may be attached to a platform of the vehicle. As the vehicle rotates, the heading of the vehicle changes. The servomotor rotates the turn sensor housing to keep the sensor at the same angular position. The heading may be determined by measuring an angular difference between the position of the turn sensor in relation to the moving object. | ||||||
