摘要： An angle sensing system for sensing a rotating angle of a steering wheel includes a sensing unit, a processing unit, and a storage unit. The sensing unit detects the rotating angle of a steering column connected to the steering wheel and outputting a sensing signal based on the rotating angle. When the steering column rotates for a circle, the sensing signal presents a non-continuous status. The processing unit calculates the relative angle in a single loop of the steering column based on the sensing signal and the number of loops according to the number of the non-continuous status. The storage unit stores the information of the relative angle and the number of loops. Based on the number of loops and the relative angle, the rotating angle of the steering wheel is detected.

摘要： A rotor (1) is of a substantially spherical shape with one complete half of the sphere (2) still remaining. The rotor (1) effective takes the shape of the head of a "mushroom." The other half of the sphere has had its material removed or omitted forming the stem (3). The depth of the cut "D" and the length "L," the radius of the sphere, will determine the ratio of the respective weights of the complete half sphere (2) and the stem portion (3). Suitably the weight of the one half to the other half of the spherical body is between about 0.75 and 0.85 and more preferably 0.8. When an external force is applied to the rotor (1), it rotates simultaneously about a pair of orthogonal axes one of which is defined by the edge (6) of the spherical body between the two halves.

摘要： A rate gyroscope having a spinning mass flexibly coupled to a rotor through a pair of orthogonally disposed, diametrically extending suspension arms. The spinning mass is adapted to pivot about the arms in response to a pair of orthogonal angular rates being measured by the gyroscope. The angular orientation of the mass with respect to the gyroscope housing provides an indication of the angular rates. An optical sensor system disposed within the housing of the gyroscope and supporting electronics are used to produce an electrical signal representative of the angular orientation of the mass and, hence, such signal provides a measurement of a pair of angular rates being measured by the gyroscope. Such sensor system includes a tilted mirror attached to an axial end of the spinning mass which reflects collimated light rays from a light emitting diode, through a reticle, to a silicon diode detector. The light passing through the reticle is modulated in accordance with the angular orientation of the spinning mass, and hence, in accordance with the angular rates being measured. The signal data is converted into an electrical signal, which after amplification and processing provides a measurement of the angular rates, such as pitch and yaw.

摘要： A flexure-pivot for providing resilient restraint that opposes relative angular displacement between two members involves two flat springs, that are held at one end between pairs of pins carried by one member and at the other end between pairs of pins carried by the other member, the flat springs each having two parallel rib portions that are linked at one end and are interlaced with one another. In one form of flexure-pivot the unlinked end of both the rib portions of each spring is secured between a pair of pins carried by one member and the linked end of both the rib portions of each spring is secured between a pair of pins carried by the other member. In another form of flexure-pivot the pairs of pins carried by one member are axially aligned with the pairs of pins carried by the other member, when there is no relative displacement between the members, and the unlinked end of one of the rib portions is secured to one of the pairs of pins carried by one member and the unlinked end of the other one of the rib portions is secured to the axially aligned pair of pins carried by the other member, so that there is a resilient interconnection between the axially aligned pairs of pins. In both forms of flexure-pivot, further pins are mounted with one or other of the members to limit relative angular displacement between the two members by engagement with pairs of pins mounted on an opposite member. Manufacture of both forms of flexure-pivot is initially the same and is carried out by inserting the ends of four pairs of pins in holes in one member, securing each end of the two flat springs between opposite pairs of pins, inserting the other ends of the four pairs of pins in holes in the other member, and brazing the assembly formed to secure the springs to the pins and the pins to the members. One form of flexure-pivot is subsequently formed by cutting two adjacent pairs of pins close to one member and the other two adjacent pairs of pins close to the other member. The other form of flexure-pivot however is formed by cutting through two adjacent pairs of pins at points between the rib portions and cutting through the other two adjacent pairs of pins at one point close to one member and at another point close to the other member.

摘要： An improved flexure hinge suspension for use in free-rotor displacement type gyroscopes is provided comprising an inner hinge unit and an outer hinge unit concentrically nested one within the other in a generally parallel manner coaxial with the gyro''s spin or reference axis. Each hinge unit, in turn, comprises a frictionless, four-bar, two-axis, universal-joint suspension element for supporting the gyro''s inertial flywheel relative to the spin axis in a particular directional mode. That is, in the outer hinge unit, the flexure bars have their respective longitudinal axes arranged perpendicular to the spin axis so as to support the flywheel against torsional and radial displacements relative to the spin axis while in the inner hinge unit the flexure bars have their respective longitudinal axes oriented parallel to the spin axis so as to support the flywheel against axial displacements along the spin axis. In each hinge unit the flexure bars comprise locally thin necked-down sections formed by machining a corresponding pair of closely spaced holes completely through the peripheral wall of each unit as the case may be. Thus, when the two units are positioned relative to each other before being rigidly fastened together, the desired exact orthogonal alignment between the flexure bars in the outer unit and the corresponding flexure bars in the inner unit may be facilitated by a simple visual inspection thereof. The flexure hinge assembly furthermore includes angle stop means for safely limiting the angular displacement of its hinge gimbals thereby preventing the delicate thin flexure bars from being overstressed or ruptured in operation.
