  • Publication number: 20140350879
    Abstract: A charge potential distributed over a vehicle body resulting from the contact, separation, and friction between a tire and a road surface is detected by a detecting unit provided with a sensing electrode that is disposed on the external surface of the vehicle body, a reference electrode that is disposed apart from the external surface of the vehicle body with a space therebetween, and a sensor amplifier that senses a potential between the sensing electrode and the reference electrode as a signal and amplifies the signal. And the amplitude of the charge potential detected by the detecting unit is monitored by a data processing unit, thereby making it possible to accurately identify not only the state of the road surface but also an internal pressure state of the tire, a wear state of the tire, and the like during vehicular travel.

  • Patent number: 4949365
    Abstract: An apparatus for measuring the density or the like of an object from the level of transmission through the object of gamma rays having different energy levels which are transmitted at the object by a gamma source having a predetermined solid angle of transmission. A collimator collimates gamma transmitted through the object and a scintillator generates light corresponding to the output of the collimator. Plural photomultipliers generate position-dependent electrical signals corresponding to the light generated by an incident gamma ray photon to the scintillator. A calculating circuit generates a density spectrum for the object from the position-dependent electrical signals by integrating the position-dependent electrical signals corresponding to each of the incident gamma ray photons to the scintillator.
