Filter status techniques adapted for use with a container based filtration device

摘要

A filter status module for use with a container based filtration device includes a dispensing sensor and a user interface communicatively coupled to a processing unit. The processing unit counts a number of dispensing events, duration and/or angle of tilt signaled by the dispensing sensor and outputs a filter status on the user interface as a function of the number of dispensing events, duration and/or angle of tilt. The processing unit may further track an elapsed period of time from insertion of a new filter and output the filter status as a further function of the elapsed period of time.

主权项

1. A device comprising:
a container; a filter that is removably coupled to the container, and
a filter status module, coupled to the container, including;
a dispensing sensor operable to detect and signal a dispensing event that has a duration and that corresponds to a tilt angle of the container;a user interface; anda processing unit, communicatively coupled to the dispensing sensor and the user interface, to time the duration of the dispensing event and correlate the duration and angle of the tilt of the dispensing event to a dispensed volume of fluid, and to output a filter status on the user interface as a function of the dispensed volume.
