  • ROBOT CONTROL SYSTEM AND CONTROL METHOD USING THE SAME
    Publication number: 20120130539
    Abstract: Provided is a robot control system including a robot which receives a final operation signal computed by a mobile terminal and includes one or more driving machines operated according to the received final operation signal, and the mobile terminal which receives a status signal of the robot and controls the robot by generating the final operation signal for directly driving the one or more driving machines included in the robot.

  • Data receiver and data receiving method
    Patent number: 7741880
    Abstract: A data receiver and a data receiving method in which the data receiver generates two comparison signals based on amplitude modulated differential input signals, amplifies the comparison signals, compares amplified signals, and outputs logic operation results based on the amplitude modulated differential input signals and the comparison signals, thereby detecting data bits. Accordingly, the number of necessary amplifiers and comparators is reduced and a separate reference voltage generator is not needed, so that chip size reduction and low-power operation is accomplished.
