    摘要： A method and apparatus are disclosed. The apparatus includes a store of at least one historical sensor measurement, a store of potential cut-off frequencies, and a filter. Each potential cut-off frequency is associated with a respective potential difference between a sensor measurement and the stored historical sensor measurement. The filter has a cut-off frequency dynamically selected from the stored potential cut-off frequencies on the basis of a difference between the stored historical sensor measurement and a current sensor measurement. The method includes determining a difference between a current sensor measurement and a historical sensor measurement; and dynamically selecting a cut-off frequency for a filter for the current sensor measurement from the difference.

    摘要： The present invention provides a method and apparatus for controlling a level in a receptacle capable of storing a fluid. The apparatus includes a first valve governing ingress of the fluid to the receptacle, a second valve governing egress of fluid from the receptacle, wherein the second valve is positioned below the first valve. The apparatus also includes a first switch deployed between the first valve and the second valve, wherein the first switch is capable of providing a first signal indicative of fluid at the first switch and a second switch deployed between the first switch and the second valve, wherein the second switch is capable of providing a second signal indicative of an absence of fluid at the second switch. The apparatus also includes a controller capable of controlling a fluid level in the receptacle by opening and closing the first and second valves responsive to the first and second signals.
