Abstract: Systems and methods for adaptive throttle filtering are disclosed. One method includes receiving vertical acceleration data indicative of a plurality of vertical accelerations of a machine, receiving first throttle pedal data indicative of a plurality of throttle pedal movements, determining a filter factor based at least on the vertical acceleration data, filtering the first throttle pedal data, based at least on the filter factor, to determine second throttle pedal data, and causing the second throttle pedal data to be transmitted to a controller to effectuate control of an operation of an engine.

Abstract: A system and method are provided for grade-based anti-hunt shift control of an automatic transmission powering a machine. A shift controller determines a recommended gear in which to operate the transmission and sets an anti-hunt timer upon recommending a shift from a first gear to a second gear. The anti-hunt timer prevents a subsequent shift back to the first gear while the anti-hunt timer is running. A grade-based controller is configured to track machine operation and to determine when the machine operational factors change such that an estimated steady state gear differs from the second gear. When such a change is encountered, the grade-based controller clears the anti-hunt timer and sets a secondary timer. The clearing of the anti-hunt timer allows a downshift to accommodate the detected grade while the setting of the secondary timer prevents a subsequent clearing of the anti-hunt timer while the secondary timer is running.

Abstract: A floor scrubber with recycled cleaning solution provides a single cleaning solution tank. Cleaning solution is delivered to powered scrubbers, and particulate-bearing contaminated cleaning solution is vacuumed from the floor after use by the scrubbers. The particulate-laden cleaning solution is returned to the storage tank through a primary large area filter located within the storage tank. Subsequently, the partially regenerated cleaning solution is pumped out of the tank through an intermediate filter and is discharged to the scrubbers through a pair of series-connected filters capable of removing very small particles from the cleaning solution. Rechargeable batteries power the unit. The unit can be operated as a self-contained unit without servicing for a period of at least about six to eight hours.

Abstract: The present invention is an apparatus for generating a signal for use in testing the purported sensitivity of a microwave receiving equipment having a noise source (105, 106) for generating a noise signal, first (112), second (114), and third (118) stage microamplifiers connected in series with an attenuator (116) for amplification and adjustment of the power level of the noise signal, a first splitter (120) connected to the output of the third stage amplifier (118), a first power meter (124) connected to a first output of the first splitter (120), a second splitter (130) receiving at its input a microwave carrier signal (127) having a specific power level, a second power meter (134) connected to a first output of the second splitter (132) and a combiner (138) connected to the second outputs of the first and second splitters (120, 130) which provides an output test signal for use in testing the carrier to noise of the microwave receiving equipment.
