摘要： An electromagnetic mark device for any type of magnetism encoder applies the electric current magnetic field as the electromagnetic mark thereof. The electromagnetic mark device comprises an insulated base plate and a thin lead wire. The thin lead wire is fixed to the insulated base plate. It is characterized in that the thin lead wire is laid out on the base plate as a circuit in a way of providing a continuously twisted and turned shape with a constant pitch. Hence, alternate magnetic marks are formed with continuous magnetic poles N·S·N·S once the current passes the lead wire. The electromagnetic mark device can be adapted to a linear ruler or a rotary dial in the magnetism encoder to detect a relative displacement, velocity and angular velocity of a moving object so that the present invention can offer more stable signals and more accurate detection of location with being fabricated more easily.

摘要： A measuring system and method of detecting an object distance by transmission media with different wave velocities are described. The measuring system has a computer, a primary detector and a secondary detector. The primary detector is connected to the computer through bus communication and the secondary detector connected to the primary one through two different transmission media. The primary detector is able to receive separately a first signal and a second signal emitted simultaneously from the secondary detector through the transmission media. Moreover, the first signal has light-speed and the second signal has sound-speed. To calculate the distance between the objects which the primary and the secondary detector are attached respectively. The delay time of second signal and the wave velocity of the supersonic media are multiplied.
