  • Patent number: 6219596
    Abstract: A vehicle borne transmitter transmits a spread spectrum transmit signal which is pseudo (PN) encoded. The transmitted signal is reflected off of a reflector on known position which may be a highway guardrail, tunnel wall, or the like. The reflected signal is detected by a receiver in the vehicle and a pseudo noise code (PN code) is synchronized to the reflected signal to accomplish maximum correlation. The phase delay between the transmitted PN code and received PN code is thereby utilized to determine the distance between the vehicle and reflector to maintain the vehicle in the center of a roadway lane. Roadway transponders may be periodically located adjacent the roadway and will be responsive to the vehicle borne interrogation signal.

  • Patent number: 5313845
    Abstract: A strain detector which is improved in corrosion resistance and moisture resistance and is high in reliability. The strain detector comprises a driven member, a magnetic shielding layer of a non-magnetic or diamagnetic material selectively formed on the driven member, a magnetic layer formed at a portion of the driven member at which the magnetic shielding layer is not formed, and a detecting coil provided corresponding to the magnetic layer. The magnetic layer may be formed in such a manner as to project from the driven member by selectively removing a surface of the driven member. Preferably, a protecting layer is formed on surfaces of the magnetic layer and the magnetic shielding layer. A process of producing such strain detector is also disclosed by which a magnetic shielding layer can be formed only at a required portion of a driven member readily in a short period of time.

  • Patent number: 5301111
    Abstract: An improved support apparatus such as a suspension apparatus for a vehicle is disclosed which has excellent response characteristics, can save power consumption and has excellent vibration-isolating capacity for isolating the transmission of high-frequency vibrations from a support member such as a road wheel to an object such as the body of a vehicle. To these end, in one embodiment, a linear motor is disposed between the object and the support member for telescopically supporting the object under magnetic effects. A position sensor senses the position of the object relative to a reference position. A low-pass filter filters high-frequency components of the output signal of the position sensor above a prescribed upper frequency limit. Based on the output signals of the position sensor and the low-pass filter, the current supply to the linear motor is controlled in such a manner as to offset a change in the output signal of the low-pass filter.

  • Patent number: 5269192
    Abstract: A strain detector to be attached to the shafts of devices such as engines, motors, electromagnetic clutches. First and second magnetic layers are disposed on the driven shaft so as to change permeability with a mechanical strain in the shaft. First and second detecting coils are wound around the first and second magnetic layers so as to be in a noncontact state therewith. Detecting means detects outputs of the detecting coils corresponding to the change in permeability. Furthermore, the driven shaft includes a heat conductive means with conductivity which is high enough to allow a temperature of each of said magnetic layers to be uniform. The outputs of the first and second detecting coils are detected in synchronism with both positive and negative drive timings of the AC drive circuit for applying an AC voltage to each of the detecting coils and smoothed and amplified thereafter, thereby allowing two strain detection outputs to be produced.

  • Patent number: 5131281
    Abstract: A strain sensing apparatus includes a pair of magnetic layers disposed on a shaft to which an external force is applied to cause strain in it. The magnetic layers have magnetic permeabilities which change in opposite directions in response to the strain in the shaft. A sensing coil is disposed to face the magnetic layers with a spacing disposed between the coil and the magnetic layers. An exciting AC voltage is applied across the sensing coil. A change in self-inductance of the coil caused by the permeability changes of the magnetic layers due to the shaft strain is derived as an electrical signal representative of the magnitude of the shaft strain.

  • Patent number: 5105667
    Abstract: In a strain measuring device employing a magnetic permeability detector means to detect an amount of strain in a passive member as changes of magnetic permeability in a magnetostrictive layer, a magnetic shielding layer is formed on the surface of the passive member, and the magnetostrictive layer is formed thereon so as to lessen the adverse effects of the passive member caused by the magnetic characteristics of the passive member in strain measurement, that is, to reduce measurement errors. Alternatively, a magnetostrictive layer is formed on the surface of the passive member, or a magnetic shielding layer is partially formed on the surface of the passive member of a soft magnetic material with high permeability, so as to lessen the influence of the passive member caused by thermal stresses of the passive member in strain measurement, that is, to reduce measurement errors. Further, there is provided a strain measuring device which facilitates formation of the magnetostrictive layer.
