With respect to the reconfigurable integrated circuit, a system for configuring an integrated circuit and a configuration method thereof which do not need a circuit overhead for variation correction and diagnosis of variation are provided. A momentary interruption detecting circuit detects a change in an output voltage when the output voltage suffers a momentary interruption over a short period of time. The system for controlling the electronic device may include a speech dialog system that controls the electronic device. The voice signal detection portion is configured to detect a communication status, control the self-adaptive filter according to the communication status, and control startup of the path change detection portion according to the communication status. The base surrounds the rear of the stapler body to provide a smooth exterior so that the device is natural to use both horizontally and vertically. The method comprises the steps of receiving the CAI on a first tuner tuned to a first channel; identifying the first tuner as the tuner receiving the CAI; and commanding the second tuner to receive the CAI after receiving a command to retune the first tuner from the first channel to a second channel.
