摘要:
An apparatus used with a range pole and survey instruments for leveling and setting elevations and a method of use of the apparatus. A frame holds a range pole, on an embed plate, without assistance of a surveyor's assistant while a surveyor communicates with an iron worker to effect elevation adjustments of the embed plate.

摘要:
An interworking function (IWF) is coupled to a switch of a packet network and communicates with the network switch based on an Ethernet clock signal or some other type of clock signal. A primary reference clock (PRC) of the network generates a PRC signal, and a timing analyzer determines timing information indicative of timing relationships between the Ethernet clock signal and the PRC signal. The timing analyzer periodically transmits such timing information, and the IWF uses the timing information to generate a PRC signal that is traceable to the network PRC signal.
