Abstract: An animal feed mechanism includes a manually operated slide valve interposed between a set of upper agitators and a set of lower screw conveyors. In some examples, two upper agitators are installed within a plastic funnel, and two lower screw conveyors are disposed within a metal auger housing. Each screw conveyor includes an auger driven by its own separate motor. Thus, there are two motors for rotating the two augers. The two motors can be energized individually to selectively rotate either auger or to rotate them concurrently. In some examples, a transmission coupling the two augers to the two agitators conveys power to rotate both agitators regardless of whether either one or both motor driven augers are operating.

Abstract: A method and system for detecting the existence of rumble strips on a roadway by a vehicle. Wheel speed data is obtained from a wheel speed sensor, and frequency-based analysis is then performed on the wheel speed data. The presence of a rumble strip can then be detected based on the outcome of the frequency-based analysis. The wheel speed data can be modified before conversion to the frequency domain to reduce wheel-induced cyclic variations in wheel speed. The frequency-based analysis can use an FFT and a peak detection method that analyzes one or more peaks in the FFT data to determine if any are indicative of the presence of a rumble strip. The method can be carried out automatically in real time and used to alert the driver of the detection of the rumble strip.
