Title: Vector approximation plotting method for function curve
Inventor: KANAZAWA TAKAHITO
IPC: G06T11/20
Filed: 1989-07-14
Abstract: PURPOSE:To express the feature of a function curve by minimum vector data required by dividing a vector into two component when the absolute value of the inclination of each vector is less than a previously determined threshold or the leght of the vector exceeds a previously determined threshold. CONSTITUTION:When the number of divisions of one period of a sine curve is defined as 10, the vector of the absolute value A = 0 of the inclination shown by vectors v3, v8 is obtained, but the vectors having the small inclination can not express the feature of the sine curve and are not desirable. In respect to the vector v3, an intermediate point x3' between the vectors x3, x4 is found out and in addition calculate y3 = sinx3 to find new point P(x3', y3') and two new vectors, i.e. v3' defining a point P2 as a start point and a point as an end point and v3'' defining a point P as a start point and a point P3 as an end point. Consequently, a curve efficiently expressing the feature of an objective curve can be plotted by the minimum vectors required without increasing the number of divisions of the curve.

Filed: 1993-06-29
Abstract: PURPOSE:To perform an authentication without the necessity of a means preliminarily storing the authentication random number and the authentication arithmetic result corresponding to each mobile station and without retrieving the authentication key of a subscriber from a data base when a subscriber authentication is performed. CONSTITUTION:At the time of the authentication of a mobile station 1, when the mobile station 1 receives an authentication request signal from a base station 2, the station 1 performs an authentication arithmetic execution and returns an authentication response to the base station 2. When a mobile object controller 3 receives an authentication confirmation signal, the controller transmits an authentication arithmetic result request to a data base 4. The data base 4 receiving it the authentication arithmetic execution, defines the obtained authentication arithmetic result as the set parameter of the response of the authentication arithmetic result and transmits the parameter to the mobile object controller 3. The mobile object controller 3 receives the response of the authentication arithemtic result and judges that the mobile station 1 is right when a collation result coincides.
