    摘要： An apparatus, method, and computer program product for detection of fluid leakage through a membrane in a fluid flow control system. The fluid flow control system has a first chamber and a second chamber. A membrane is disposed between the first chamber and the second chamber. The second chamber has a connection to a pressure tank, the pressure tank has a fluid with a pressure, and the connection defines a fluid path. The method indudes in a first step, blocking the fluid path. The pressure of the fluid in the pressure tank is then adjusted. The pressure is measured in the pressure tank which creates a pressure measurement at each of a first set of multiple timed intervals while the fluid path is blocked and after the pressure is adjusted. A blocked pressure rate is calculated based on the pressure measurements in the pressure tank at the first set of multiple timed intervals. Next, the fluid path is unblocked. The pressure is measured within the pressure tank creating a pressure measurement at each of a second set of multiple timed intervals after the fluid path is unblocked. Then, an unblocked pressure rate is calculated based on the pressure measurements in the pressure tank at the second set of multiple timed intervals. Finally a leakage rate is calculated based on the blocked pressure rate and the unblocked pressure rate. An alarm is caused when the leakage rate becomes greater than a predetermined threshold value.

    摘要： A method for communicating data in a rail vehicle consist includes transmitting first data at a first rail vehicle of the consist over a power supply conductor to a second, different rail vehicle in the consist, where at least one rail vehicle of the consist receives direct electrical power from the power supply conductor. The method also includes monitoring the power supply conductor for second data at the first rail vehicle and receiving the second data over the power supply conductor at the first rail vehicle for use by a first system onboard the first rail vehicle. In one aspect, the transmitting step comprises transmitting the first data over one or more of a catenary line or a third rail that supplies the electrical power.
