    • An electronic switch can replace a standard mechanical light switch for 110-240 volt alternating-current (A.C.) devices. A triac switches the A.C. current to an A.C. device such as a light. A rectifier bridge generates a direct-current (D.C.) voltage that is applied to a special current limiter. The special current limiter generates a large current peak at low voltages, but limits current at high voltages. The large current peak from the special current limiter charges a capacitor when voltage is low at the beginning of each A.C. half-cycle, before the triac turns on. The capacitor has enough charge to supply D.C. current to an Infrared detector and trigger control logic for the rest of the A.C. half-cycle. When the detector detects a person nearby, it signals the trigger control logic. The D.C. voltage from the rectifier bridge is filtered to generate a sync pulse to the trigger control logic when adds a phase delay to the sync pulse which triggers the triac.
    • 电子开关可以替代110-240伏交流(交流)装置的标准机械灯开关。 三端双向可控硅开关将交流电流切换到交直流设备,如灯。 整流桥产生施加到特殊限流器的直流(直流)电压。 特殊电流限制器在低电压下产生大电流峰值,但限制高电压下的电流。 在三端双向可控硅开关导通之前,每个交流电半周期的电压低电平时,特殊电流限制器的大电流峰值将对电容器充电。 电容器具有足够的电荷,以将红外线检测器的电流提供给红外检测器,并触发交流半周期的其余部分的触发控制逻辑。 当检测器检测到附近的人时,它会发出触发控制逻辑信号。 当对触发三端双向可控硅开关元件的同步脉冲添加相位延迟时,来自整流桥的直流电压被滤波以产生到触发控制逻辑的同步脉冲。

    • A short message sending method, a short message service center (SMS-SC) and a gateway are provided. The short message service center constructs a message body for bearing short message, includes routing information of the short message in this message body, and sends the message body to a short message mobile switching center gateway; after receiving the message body and determining that the message body includes the routing information of the short message, the short message mobile switching center gateway sends the short message to a core network service node according to the routing information. The SMS-SC sends the obtained routing information together with the short message to an SMS-GMSC, so that the SMS-GMSC does not need to request the routing information from an HSS or an HLR, which can reduce the interactive signaling, save the network resources, and optimize the system performance.
    • 提供短消息发送方法,短消息服务中心(SMS-SC)和网关。 短消息服务中心构建用于承载短消息的消息体,包括短消息在该消息体中的路由信息​​,并将消息体发送到短消息移动交换中心网关; 在接收到消息体并确定消息体包括短消息的路由信息​​之后,短消息移动交换中心网关根据路由信息将短消息发送到核心网业务节点。 SMS-SC将获取的路由信息​​与短消息一起发送到SMS-GMSC,使得SMS-GMSC不需要从HSS或HLR请求路由信息,这可以减少交互信令,保存 网络资源,优化系统性能。
