摘要： An improved absolute position detection method is provided for a stroke sensing cylinder which includes a magnetic scale detecting step for obtaining a plurality of sine wave form voltages having different phases using a magnetic sensor unit in accordance with a driving operation of the cylinder. A wave form generation step is also provided for converting the sine wave form voltage obtained in the magnetic scale detection step into a square wave form and generating a triangle wave form having the same period as the thusly converted square wave form. A first absolute position value detection and stroke direction judging step is then provided for judging a first absolute position value and stroke direction of the cylinder using a pair of square and triangle wave forms generated in the wave form generation step. Lastly, a second absolute position value computation and storing step is provided for computing and storing a second absolute position value having a predetermined value based on the first absolute position value. The method of the present invention is directed to detecting a magnetic flux change of a magnetic scale using a plurality of magnetic sensors. The magnetic scale is disposed along the cylinder rod and includes at least one different magnetic scale processing period contained within a regularly protruded and recessed portion. Signal-processing is achieved using a microprocessor and a 1/N-dividing counter. The thusly signal-processed wave forms are counted and an absolute position and stroke direction is determined.

摘要： The invention relates to an electric circuit for measuring the length of a shock absorber unit of a vehicle, comprising: a coil with windings which are fitted around the shock absorber unit, of which a casing of electrically conducting material connected to a part of the wheel suspension of the vehicle is axially movable relative to the coil when there is a change of length of the shock absorber unit as a result of a change in the force absorbed by the wheel suspension; an oscillator connected to the coil, for exciting the coil with an excitation signal of a predetermined frequency; and processing means which are connected to the coil and are designed for determining the value of a relation between the voltage across the coil and the current through the coil, which value is a measure of the length of the shock absorber unit. In this connection, the length of a shock absorber unit should be understood as the distance between two fixing points thereof in the wheel suspension, while the wheel suspension of the vehicle should be understood as the damped spring construction which couples a wheel in a supporting manner to the body. In this case, the casing of the shock absorber unit can be connected to the body and the coil to the wheel, or the casing can be connected to the wheel and the coil to the body. The term vehicle should be understood not only as a road vehicle such as a lorry or private car, but also as a rail vehicle or an aircraft on the ground.

摘要： An apparatus and method for controlling damping force characteristics of shock absorbers independently of one another, the damping force coefficient for each shock absorber being controlled on the basis of so-called "sky hook" theory with respective sprung mass vertical velocities and relative velocities between the sprung mass and unsprung mass taken into consideration. The relative velocity detecting sensors are only installed on portions of the vehicle related to front left and right tire wheels. The road surface velocities on the front left and right tire wheels are calculated and the road surface velocities on the rear left and right tire wheels are calculated on the basis of the calculated front left and right wheel road surface velocities, a vehicular wheel base length, and a vehicle speed. Then, relative velocities between the sprung mass and unsprung mass related to the rear left and right tire wheels are calculated on the basis of the calculated rear left and right tire wheel road surface velocities and sprung mass vertical velocities related to the vicinities of the rear left and right tire wheels.

摘要： An optical table active leveling and vibration cancellation system is disclosed. The system includes an optical table with three active isolation devices connected to the optical table, and one sole pneumatic device, such that the table is supported on all four corners. Each of the isolation devices includes a pneumatic suspension device and an electromagnetic suspension device. The pneumatic suspension device includes a pressurized load chamber, a gimballed piston received in the pressurized load chamber and coupled to the walls of the pressurized load chamber by a thin walled diaphragm, and a support rod extending from the optical table to the floor level. The electromagnetic bearing suspension device includes a magnetic bearing rotor having two planar surfaces and a peripheral surface, and two magnetic bearing stators, the stators each defining a central aperture and each stator being in a spaced apart relationship from each of the rotor planar surfaces. The rotor is secured to the support rod. Each of the stators includes an annular coil of wire. The electromagnetic suspension system may also include four radial electromagnets spaced around the peripheral surface of the rotor. The radial electromagnets also include an annular coil of wire. The system also includes three proximity sensors mounted under the optical table to detect motion of the table in relation to the floor or another fixed reference, and generate a signal in response to the motion. The system also includes three accelerometers mounted underneath the optical table in a triangle. The accelerometers measure vibration of the table in relation to inertial space and generate a signal in response to the movement. A controller receives the signals from the sensors and accelerometers, and generates a second signal, used to activate the pneumatic and electromagnetic bearing suspension devices to provide active leveling and vibration cancellation of the optical table.

摘要： A linear position sensor includes coextensively positioned primary and secondary windings, each having an elongated core and a coil radially spaced around the core. A cyclically varying signal is applied to the primary winding which develops a signal across the secondary winding due to transformer coupling. A coupling adjustment member varies the amount of transformer coupling and is longitudinally movable with respect to the winding assembly. The relative longitudinal positioning of the coupling member with respect to the winding assembly is determined by measuring the signal developed across the secondary winding. In one embodiment, the windings are similarly configured, are arranged side-by-side and spaced apart; the coupling adjustment member enhances the transformer coupling between the windings which are telescopingly received within the member. In another embodiment, one winding is concentrically positioned within the other and the coupling adjustment member disrupts the transformer coupling between the windings by being positionable in a gap between the windings. Embodiments are illustrated both for location internal to, and external of, a vehicle shock absorber.

摘要： The invention concerns a method whereby not only the relative speed of the body and axle but also a dashpot's farthest-in and farthest-out positions can be measured without using complicated and expensive sensors. Relative speed is detected with a known combination of sensor coil and permanent magnet. The induced voltage at the midsection of the coil is proportional to relative speed. The voltage induced as the end of the coil is traveled by is exploited as a signal representing the dashpot's farthest-in and farthest-out positions.
