Abstract: The invention is directed to an arrangement for monitoring a road condition which determines the coefficient of friction of the road surface on the basis of a signal corresponding to an acceleration of a vehicle detected by an acceleration sensor. The signal is converted into one of at least two predetermined values by conversion means in response to a magnitude of the acceleration every cycle of a predetermined time period. The converted value is summed up by summing means by a predetermined number of consecutive cycles to provide a total value in the last cycle thereof which is stored in memory means. Then, in determination means, one of at least two standard values is selected in response to the condition of increase or decrease of the total value in the present cycle provided by the summing means as compared with the total value in the previous cycle stored in the memory means. And, the total value in the present cycle is compared with the above one of at least two standard values to produce a road condition signal corresponding to a result of comparison which represents the coefficient of friction of the road surface. The present system is applicable to an anti-skid control system for an automotive vehicle.

Abstract: There is an image processing apparatus such as a copying apparatus for processing an input image data. This apparatus comprises: an image scanner such as a CCD to digitally read out the image data from a document; a discriminating unit to discriminate whether the input image data is the halftone image data such as a photograph or single density image data such as characters or symbols; a magnification change unit to change the magnification of the image data; and a smoothing unit to smooth the image data in the case where the discriminating unit decides that the input image data is the halftone image data when the magnification change unit performs the magnification changing process. The discriminating unit executes the above discrimination on the basis of the density levels of or density difference between a target pixel and its peripheral pixels in the input image data. With this apparatus, the magnification of the halftone image can be smoothly changed.

Abstract: An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.
