    摘要： An initial positioning system and method for liquid measuring and taking. The system comprises a measuring passage, a variable pressure chamber, and a piston, an initial end of the measuring passage being in communication with the upper part of the variable pressure chamber; the piston reciprocates in the variable pressure chamber to cause a change between positive pressure and negative pressure in the variable pressure chamber; the initial positioning system further comprises a pressure relief port located on the wall of the variable pressure chamber and capable of communicating with the outside of the variable pressure chamber; when the piston is located at the pressure relief port, and the inside and outside of the variable pressure chamber are in communication, the maximum volume of the liquid that can be accommodated in the variable pressure chamber is not smaller than one third of the total volume of the variable pressure chamber.

    摘要： An apparatus for managing contention in a communications system, the apparatus comprising a processor and a non-transitory computer readable storage medium storing programming for execution by the processor. The programming may include instructions to receive a ranging code from a device in a ranging channel, the ranging code corresponding to a current ranging attempt. The programming may further include instructions to broadcast a message acknowledging reception of the ranging code. The programming may further include instructions to receive a ranging request message from the device, the ranging request message comprising a ranging retries parameter that specifies a number of ranging retries that the device performed during the current ranging attempt.
