IPC: G06T11/20
Filed: 1991-11-20
Abstract: PURPOSE:To calculate an area rate at high speed without counting the number of divided and painted-out sub pixels by providing an approximate area rate calculating means to calculate the approximate area rate of edge part picture elements. CONSTITUTION:This device is equipped with a CPU 202 to control the entire device according to various control programs and a font ROM 203 storing vector fonts or the like. A continuation information adding means generates vector data to form the outline of a graphic and continuation information showing continuity with the vector data and adds the data and the information to vector information. Next, based on the continuation information of the vector data, a pseudo vector generating means generates a pseudo vector from upper and lower scan lines with a scan line between and the information of intersections with the vector data. Continuously, the approximate area rate of the edge part picture elements is calculated by using the decimal part of an X coordinate value or a Y coordinate value at any one of two intersections formed when the pseudo vector passes through the edge part picture elements.

Title: Apparatus for estimating state of road surface
Inventor: YAMAMOTO SHINSUKE
IPC: B60T8/1763
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To estimate a friction coefficient of a road face highly accurately by sequentially detecting maximum values of a velocity of a driven wheel in a fixed time and estimating a state of the road face based on the maximum values. SOLUTION: Velocities of driven wheels 10, 12 are measured by driven wheel velocity sensors 52, 54 and input to an electronic control device 46. The velocities are compared with previously stored velocities in the device 46, and a larger velocity is set as a driven wheel velocity for use in operating a friction coefficient of a road face. A timer count value (t) is increased 1, which is compared with a friction coefficient operation cycle T. When the count value (t) is smaller, the process is returned to the beginning and repeated again. When the count value (t) reaches the cycle T, the driven wheel velocity at the time point is set as a maximum driven wheel velocity this time, from which a friction coefficient of the road face this time is obtained. Thereafter, the count value (t) is cleared to zero. Since a peak value of the driven wheel velocity is held in this manner, the friction coefficient of the road face can be estimated highly accurately even if the wheel velocity is changed, e.g. on a bad road or by the like reason.
