摘要： The present invention provides a technique using current sensing to control the pressure at constant level without the direct sensing of the pressure. This technique will help to reduce dependency solely on switch or sensor and their non linearity and other associated problems such as the non-repetitive behavior, being affected by EMI etc. The technique includes using a pump controller featuring one or more modules configured to respond to one or more input signals containing information about current provided from a pump; and configured to provide one or more output signals containing information to control the pump to operate at a substantially constant pressure without the direct sensing of pump pressure. The one or more modules control the operation of the pump based at least partly on a table of characteristics related to voltage and current that is calibrated for each pump.

摘要： The present invention provides a new and unique portable, self-contained, fluid system. The portable, self-contained, fluid changing system may be used as a fluid changing device for changing a fluid such as oil or another suitable fluid in a container of a boat, recreational vehicle (RV), automobile or other suitable military, agricultural or industrial device. Alternatively, portable, self-contained, fluid system may also be used for providing fluid such as water or other suitable fluid for cleaning or showering. Moreover, the portable, self-contained, fluid system may also have a reversible electric pump that may be adapted or switched for pumping in either direction once the pump is affixed on the reservoir so the system may be sold and marketed for use in a fluid changing type of device or in a water providing or cleaning type of device consistent with that described above.
