    • A method and system for controlling fuel injection for vehicles controls fuel injection amount according to change in kinetic energy of the vehicle or performs fuel cut control so as to improve fuel economy. The method may include setting a first energy line corresponding to energy loss due to running resistance when deceleration, setting a second energy line corresponding to energy loss due to engine friction, determining whether kinetic energy of the vehicle is above the first energy line after a predetermined time has elapsed, and injecting fuel by an amount generating energy corresponding to a sum of engine friction energy and braking energy in a case that the kinetic energy of the vehicle is above the first energy line.

    • A method is provided for checking whether information on a request for a mode change is received for a prescribed channel time such that a device configuring a network enters a power save mode when not performing data transmission/reception and a modem enters an awake state from a sleep state for the prescribed channel time. The prescribed channel time is determined to correspond to a time for transmitting a beacon. The modem of a device in a power save mode enters an awake state for a channel time period for broadcasting a beacon and then checks whether information on a power management mode change is received. If the information is not received, a sleep state is reentered. If the power management mode change information is received, power is managed by performing data transmission/reception by switching to a normal mode.
    • 提供了一种方法,用于检查在规定的频道时间内是否接收到关于模式改变的请求的信息,使得当不执行数据发送/接收并且调制解调器进入唤醒状态时,构成网络的设备进入省电模式 睡眠状态为规定的通道时间。 确定规定的通道时间以对应于发送信标的时间。 节电模式的设备的调制解调器进入用于广播信标的信道时间段的唤醒状态,然后检查是否接收到关于电源管理模式改变的信息。 如果没有收到信息,则重新进入睡眠状态。 如果接收到功率管理模式改变信息,则通过切换到正常模式来执行数据发送/接收来管理功率。

    • The present invention relates to a handover method that a current coordinator transfers a coordinating function of controlling a network to a different device configuring the network. The present invention relates to a method of selecting an optimal device as a coordinator in selecting the different device using priority information decided by a prescribed evaluation reference. And, the present invention relates to a method of simplifying a procedure in a manner of transmitting relevant information together with a handover request message. In a wireless network including a coordinator, a secondary coordinator is decided in advance. If the coordinator is suddenly unable to perform a function, the present invention relates to a method of enabling the function of the coordinator to be performed by the decided secondary coordinator. Thus, a process for transferring the coordinating function without the handover process is called a recovery process. The present invention relates to the recovery method and a method of deciding a secondary coordinator to perform a recovery. In the method of deciding the secondary coordinator, a method of deciding a more proper coordinator using information on coordinator priority is provided.
    • 本发明涉及一种当前协调器将控制网络的协调功能传送到配置网络的不同设备的切换方法。 本发明涉及一种选择最佳设备作为协调器的方法,该方法是使用由规定评估参考决定的优先级信息来选择不同设备。 并且,本发明涉及以与切换请求消息一起发送相关信息的方式来简化过程的方法。 在包括协调器的无线网络中,预先确定辅助协调器。 如果协调器突然不能执行功能,本发明涉及一种能够由所确定的辅助协调器执行协调器的功能的方法。 因此,在没有切换处理的情况下传送协调功能的处理被称为恢复处理。 本发明涉及恢复方法和决定辅助协调器以执行恢复的方法。 在确定辅助协调器的方法中,提供了使用关于协调器优先级的信息来决定更合适的协调器的方法。

    • A wireless network system includes a coordinator, a first device, and a second device. The coordinator transmits a first response to the first device to approve a first request message received from the first device; broadcast a first beacon, indicating that the first device is in a power saving mode, after transmitting the first response; transmit a second response to the second device to approve a second request message received from the second device; broadcast a second beacon, indicating that the first device needs to change a power management mode from the power saving mode to a normal mode, after transmitting the second response; transmit a third response to the first device to approve a third request message received from the first device; and broadcast a third beacon, indicating that the first device is in the normal mode, after transmitting the third response.
