Abstract: A touch input device includes two or more interleaved scroll sensors. A common area is interposed between two of the scroll sensors. A sense line snakes through the common area. Scrolling pressure applied to a sense layer causes the sense layer to contact and electrically connect the sense line to the scroll sensors thereby permitting the scrolling pressure position to be determined by measuring a voltage on the sense line. The scroll sensors are potentiometric and may be linear strip scroll sensors or rotary ring scroll sensors. The interleaved scroll sensors with the common area allow smooth scrolling action from one major leg to another major leg.

Sessions are ended between each terminal and server if either the alive report packet or the talk burst idle packet are not received for a certain time. Accordingly, synchronization between the server and the terminal is periodically certified, unnecessary traffic generated due to inconsistent synchronization is decreased, and quality of service is enhanced.
