Abstract: Fluid filtration devices and methods of filtering fluids are described. The devices generally include a housing, a hollow filter assembly, a rotating cleaning assembly and a device to measure the accumulation of solids in the filter housing. In some embodiments the accumulation of solids is measured by measuring the torque required to rotate the cleaning assembly. Torque may be measured directly, such as with a torque sensor, or indirectly, such as by measuring the current used by an electric motor to drive rotation of the cleaning assembly. In some embodiments a purge valve is opened to remove accumulated solids from the housing when a certain level of solids accumulation is detected.

Abstract: A bracket for supporting a radar detector or like device on the windshield of a motor vehicle such that the device is readily accessible to the user. The bracket generally includes a substantially planar support which has first and second portions disposed at an acute angle to one another. Secured to the second portion of the support are two main suction cups and one secondary suction cup which may be adjusted according to the slope of the vehicle windshield. The radar detector or like device is secured to the first portion of the support which is maintained in a horizontal position upon mounting the bracket.
