Filed: 2000-12-23
Abstract: PURPOSE: A steering device of wheels for a vehicle is provided to prevent accidents by aligning wheels straight in parking the vehicle on the horizontal plane, and by steering wheels for the wall in parking on the inclined road. CONSTITUTION: A light sensor(51) checks the rotational angle of a steering shaft, and transmits the rotational angle to an ECU(Electronic Control Unit)(E). The ECU arranges the steering shaft for rectilinearly traveling by driving a motor(54). A slope sensor(1) applies information to the ECU by checking inclination of the vehicle, and two side sensors(2,3) transmit information to the ECU by detecting the state of both walls. A pinion(53) and a worm(52) are turned with rotating the motor, and the steering shaft is turned clockwise. The motor is stopped in turning wheels, and rolling of the vehicle is prevented with aligning wheels for the wall in parking the vehicle on the inclined road. Accidents are prevented with turning wheels for the wall in parking the vehicle on the inclined way.

Abstract: PURPOSE: A call forwarding method is provided to transfer an incoming call to another number in a web phone system. CONSTITUTION: In case that it is judged that a selective call forwarding mode is set, a call control block sends an announcement voice about route selection to the terminal of an external user who has made a call(117). If the external user selects a desired route according to the announcement voice, the call control block receives the selected route(119) and judges whether the selected route is identical to the presently occupied route(121). In case that the selected route is not identical to the presently occupied route, the call control block judges whether the selected route is an IP route(131). If the selected route is the IP route, the call control block receives the IP of a terminal to attempt a call connection from the external user(133) and dials to the received IP(137). In case that the call connection is successful, the call control block terminates the call forwarding process(139).
