Abstract
A system including a first element to provide a first parameter value that varies with a first temperature of fluid adjacent the first element, a second element to provide a second parameter value, the first element connected to the second element at an output such that output signals at the output correspond to differences between the first parameter value and the second parameter value, a heater element situated between the first element and the second element to provide heat to the fluid, and a circuit to evaluate the output signals at the output and a threshold value that corresponds to a fluid flow set point and to determine whether flow of the fluid, in at least one direction, across the first element, the heater element, and the second element exceeds the fluid flow set point.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
