Abstract: A system and method for compensating the output of an uncompensated Hall Effect sensor used to monitor an output shaft of an actuator. The actuator includes an output shaft, a magnet coupled to the output shaft, a motor for rotating the output shaft between a first position and a second position and an electronic control module having a controller, a diode and an uncompensated Hall Effect sensor.

Abstract: An actuator having an output shaft, a motor for rotating the output shaft between a first position and a second position, and an electronic control module having a controller and a sensor. The sensor is configured to output a signal to the controller indicative of the position of the output shaft, and the controller is configured to determine whether the output shaft is in the first position or the second position.

Abstract: A power window system equipped with a "one-touch-down" feature for a motor vehicle includes provisions for programming the system to enable and/or disable the one-touch-down feature. The programming is done via a sequence of commands provided to the controller of the one-touch-down feature from various switches on the motor vehicle. In the preferred embodiment of the present invention, all such commands are issued from devices already on the vehicle to perform functions other than programming of the "one-touch-down" feature.

Abstract: A plurality of sensors, such as a door handle lift switch, a headlight switch, and an ignition switch, are normally provided in an automotive electrical system. A master microcontroller normally is coupled to each of these sensors for receiving a signal therefrom and responsive thereto generating a corresponding controller signal. Power drivers, each operatively coupled to the master controller, normally are provided for energizing and powering loads coupled thereto, with each load being either an indicator or actuator that is operated responsive to its corresponding sensor. The self-diagnostic method includes the steps of mechanically actuating a selected one of the sensors, and then electrically actuating a first confirming indicator, such as an audible chime, indicative of the master controller receiving and successfully processing the corresponding sensing signal.

Abstract: In a transmission system having range shift levers mechanically linked to couplers and shiftable between first and second positions to select ranges of gears and electro-hydraulic powershift clutches for selecting a gear within the range selected by the range shift lever, the powershift clutches are located on each side of at least one of the couplers, between the input shaft and the coupler and between the output shaft and the coupler. A dump solenoid is controlled by operation of a clutch pedal to release fluid from the powershift clutches as the clutch pedal is depressed but before it reaches the fully depressed position so that the coupler is not being driven when coupler shifting takes place.

Abstract: Stall current levels are determined according to measured peak currents occurring immediately after the energization of a motor. By utilizing a fractional value of the determined peak current value, the stall current is determined each time the motor is energized to compensate for variations in current flowing in a motor at different ambient temperatures.

Abstract: An active clamp circuit for an inductive load switching circuit includes a zener current control resistor to set the breakdown current in a zener diode of the clamp circuit. The zener breakdown current is set at a sufficiently high level to ensure that the zener diode is operated at a point beyond its "knee" region and therefore does not generate interfering levels of microplasmic noise (MPN). The zener current control resistor is provided in addition to a circuit speed control resistor such that there is substantially independent control of the switching circuit operating speed and the breakdown current of the zener diode of the active clamp circuit.

Abstract: A tractor coupled to a draft implement through at least one link arm of a hydraulic lift assembly having a lift rod coupled between each link arm and a hydraulic cylinder for raising and lowering the draft implement. A force sensor is coupled to a link arm for providing a measurement of the total force exerted on the link arm. Electrical circuitry provides a measurement of the actual draft force by correcting the total force measurement for lift forces transmitted to the link arm through the corresponding lift rod. A feedback or draft control system is also provided for adjusting the depth of the draft implement in inverse relation to the corrected measurement of actual draft force.

Abstract: A control system and method for adjusting the depth of a tractor-drawn draft implement in response to a detection of draft load. The control system compares actual engine rpm to a stored or mapped value of engine rpm at zero engine load conditions for the throttle setting in use. An indication of engine lug-down is thereby obtained. Through the use of another memory related to the engine torque versus rpm curve, for the actual throttle setting in use, a draft load signal is obtained. As determined by an operator sensitivity setting, a preselected portion of the draft load signal is then combined with a preselected portion of an actual draft depth position signal to form a feedback signal. A signal represntative of the draft depth desired by the operator is then combined with the feedback signal to form a command signal for raising or lowering the draft implement via a hydraulic powerlift valve.

Abstract: A fuel efficiency monitor (10) for a tractor for agricultural use includes sensors (22, 24) for detecting engine operating conditions, an engine map means (38, 42) for correlating efficiency to the engine operating parameters, and a display (14) to display an indication of efficiency to the tractor operator.
