| 037413000 | With alarm, indicator, signal, or inspection means | 7 |
| 20080313935 | Electronic Parallel Lift And Return To Carry On A Backhoe Loader - A backhoe loader with a controller that uses angular signals from at least one sensor to calculate a loader tool angle with respect to the vehicle frame or with respect to the earth and to maintain the loader tool angle via controller generated commands to a tool actuator as a function of the angular signals and commands to a boom actuator. The controller enables proportional control of the tool angle via a command input device such as an electronic joystick. If the electronic joystick is moved to an appropriate detent position, the controller executes a return to carry function. | 12-25-2008 |
| 20090038186 | Extendable frame work vehicle - An extendable frame work vehicle offering enhanced versatility, safety and effectiveness. The vehicle includes an adjustable frame with front and rear portions that extend or retract with respect to each other. The front portion is supported by a first pair of wheels and said rear portion is supported by a second pair of wheels. Each wheel is independently driven and steered. The vehicle also includes an engine mounted on the rear portion of the frame. Incorporated into the vehicle is an electro-hydraulic assembly which enables extension and retraction of the adjustable frame. The assembly includes a sensor-responsive microprocessor controller, at least one hydraulic pump, at least one hydraulic drive motor, and at least one valve network. | 02-12-2009 |
| 20090139119 | Payload system that compensates for rotational forces - The present disclosure is directed to a payload calculation system for use with a work implement. The payload calculation system may have a state sensor configured to measure a state of the work implement. The payload calculation system may further have a processing device configured to calculate a mass of a payload moved by the work implement. The processing device may be configured to use the measured state to compensate the calculation of the mass for centrifugal, inertial, and frictional forces of the work implement caused by the work implement rotating about a vertical pivot. | 06-04-2009 |
| 20090265962 | Avoidance system for locating electric cables - An avoidance system for a mobile earthmoving machine is disclosed. The avoidance system includes a sensor system configured to periodically detect a position of a cable tethered from the machine within a worksite and generate a position data set in response thereto. A controller is associated with the sensor system and configured to determine a cable avoidance region based on the position data set. | 10-29-2009 |
| 20120144704 | CYCLE COUNTER FOR WHEELED TRACTOR SCRAPER - A cycle counter for a wheeled tractor scraper is disclosed. The cycle counter may have an ejector configured to push material from a bowl of the wheeled tractor scraper, a sensor configured to generate a pressure signal indicative of a position of the ejector, and a controller in communication with the sensor. The controller may be configured to determine movement of the ejector toward a full dump position based on the pressure signal, and to record completion of a cycle for the wheeled tractor scraper after the ejector has reached the full dump position only if a value of the pressure signal exceeded a threshold value during movement of the ejector toward the full dump position. | 06-14-2012 |
| 20130283648 | GUARD FOR SENSOR APPARATUS IN TILTING ARRANGEMENT - A guard for a sensor apparatus in a tilting arrangement. The guard includes a first tubular portion supported on the tilting arrangement, a longitudinal portion extending from the first tubular portion, and a second tubular portion extending from the longitudinal portion. The first tubular portion provides a first cavity adapted to partially enclose a first mounting stud of the sensor apparatus. Similarly, the second tubular portion provides a second cavity adapted to partially enclose a second mounting stud of the sensor apparatus. And, the longitudinal portion provides a recess adapted to partially enclose a lever member of the sensor apparatus. | 10-31-2013 |
| 20140237868 | LOAD ESTIMATOR FOR SCRAPER - A load estimator is disclosed for use with a scraper. The load estimator may have a first sensor configured to generate a first signal indicative of a performance parameter of the scraper, a second sensor configured to generate a second signal indicative of a hydraulic pressure associated with a bowl of the scraper, and a controller in communication with the first and second sensors. The controller may be configured to classify a current segment of an ongoing work cycle based on the first signal. The controller may also be configured to selectively estimate a load of material contained with the bowl of the scraper based on the second signal only when the current segment is classified as a segment where the load can be reliably estimated. | 08-28-2014 |
