Abstract: A method for controlling a multi-phase motor includes withholding energization of a first phase of the motor for a non-zero period when the first phase's dwell time begins. Energization of the first phase is activated upon the expiration of the non-zero period. Energization of the first phase is deactivated for the remainder of the dwell time at a deactivation time occurring before or at the expiration of the dwell time.

Abstract: A peer-to-peer (P2P) network system and a method of operating the P2P network system are provided. The P2P network system includes at least one edge peer storing resources and at least one super peer sharing and managing resource information corresponding to the resources of the at least one edge peer. By updating changes in characteristics of peers due to elimination and movement of any one of a plurality of edge peers and super peers included in the P2P network, path reconfiguration may be performed efficiently.

Abstract: Provided is a backward motion control technology for a car. The car comprises a backward-motion control terminal, a control signal converter, and a backward-motion controller. The backward-motion control terminal outputs a first backward-motion control signal corresponding to a backward velocity and a backward direction of the last trailer according to a user's operation. The control signal converter converts the first backward-motion control signal to a second backward-motion control signal which corresponds to a backward velocity and a backward direction of the car. The backward-motion controller controls the car based on the second backward-motion control signal so that the last trailer moves backward by the backward velocity and the backward direction corresponding to the first backward-motion controlling signal.
