Abstract: A system and method for measuring the flow of water in cross-section of a body of water is presented. The system and method comprises a housing having a first transducer and a plurality of second transducers, wherein the first transducer produces an acoustic signal for determining the depth of the body of water, and the second transducers each produce an acoustic signal for determining the velocity of a volume of water by measuring the Doppler frequency shift in the returned echo.

Abstract: A method of communicating with a printing system over a communications network using a rule-based protocol. The method includes building a rule-based protocol request message on a remote processing system. The rule-based protocol request message includes an operator name. The remote processing system transmits the rule-based protocol request message from remote processing system to the printing system over the communications network. The remote processing system determines whether the remote processing system receives a rule-based protocol response message from the printing system. When the remote processing system receives the rule-based protocol response message from the printing system, the remote processing system reads an attribute name associated with the operator name. The rule-based protocol response message includes the attribute name.
