    • A ratchet wrench includes a body, a ratchet wheel, a pawl, a switch member and a resilient member. The body has three recesses to respectively accommodate the ratchet wheel, the pawl and the switch member. The pawl has a driving portion to be engaged with the toothed portion of the ratchet wheel. The pawl has a second engaging portion which is engaged with a first engaging portion of the ratchet wheel to position the ratchet wheel and the pawl in the two respective recesses respectively. The pawl has a protrusion which has a curved recess and a first stop. The switch member has a second stop, a reception recess and a hole. The protrusion is accommodated in the reception recess. The resilient member extends through the hole and the two ends of the resilient member contact the reception recess and the curved recess respectively.
    • 棘轮扳手包括主体,棘轮,棘爪,开关构件和弹性构件。 主体具有三个凹槽,以分别容纳棘轮,棘爪和开关构件。 棘爪具有与棘轮的齿部接合的驱动部。 棘爪具有第二接合部分,其与棘轮的第一接合部分接合,以将棘轮和棘爪分别定位在两个相应的凹部中。 棘爪具有突起,其具有弯曲的凹部和第一止挡部。 开关构件具有第二止动件,接收凹部和孔。 突起容纳在接收凹部中。 弹性构件延伸穿过孔,并且弹性构件的两端分别与接收凹部和弯曲凹部接触。

    • After transitioning a network interface of a first wireless communication device from a low power state to an active state, transmitting a request for a second wireless communication device to transmit data for the first wireless communication device that is buffered at the second wireless communication device. An indication of whether there is data for the first wireless communication device buffered at second wireless communication device is received. When there is data for the first wireless communication device buffered at second wireless communication device, data for the first wireless communication device that was buffered at the second wireless communication device is received from the second wireless communication device.
    • 在将第一无线通信设备的网络接口从低功率状态转换到活动状态之后,向第二无线通信设备发送对第二无线通信设备发送数据的第一无线通信设备的数据进行缓冲。 接收在第二无线通信设备中缓存的第一无线通信设备是否存在数据的指示。 当存在在第二无线通信设备中缓存的第一无线通信设备的数据时,从第二无线通信设备接收在第二无线通信设备处缓冲的第一无线通信设备的数据。
