Abstract: A high side driver circuit includes a command voltage source, a first switching transistor having a base connected to the command voltage source, an emitter connected to ground, and a collector connected to a second switching transistor base. The second switching transistor includes an emitter connected to an electrical energy source through an internal voltage source. A power transistor includes a gate connected to the second switching transistor collector through a resistor, a drain connected to the electrical energy source through a sense resistor, and a source connected to a load. A diagnostic circuit portion including a comparator establishes a diagnostic output voltage based upon the state of the power transistor and characteristics of the power transistor drain and source for indicating fault conditions of the driver circuit.

Abstract: The invention is a system and method for managing a resource having a dump location. A plurality of stop points are located adjacent to the dump location. Each of a plurality of mobile machines includes a queue manager adapted to generate a queue position request signal as each mobile machine approaches the resource. A resource manager is adapted to establish and control a queue to control access to the resource in response to receiving a queue position request signal. The resource manager is also adapted to enable simultaneous access of the dump location by the mobile machines.

Abstract: The present invention is adapted to control the motion of a seat 102 located in a seat suspension system 100. The present invention determines a total damping force based on an absolute velocity damping force and a relative velocity damping force. Based on the absolute and relative damping force, a total damping force is determined which will provide a smooth ride for the operator throughout the range of travel of the seat, while prevention collisions with the end stops.

Abstract: The invention is a system and method for managing a resource having multiple entry points. Each mobile machine includes a queue manager for generating a queue position request upon approach to the resource. A resource manager establishes queues, one for each entry point to the resource, to control access to the resource. Upon receiving a queue position request from an approaching mobile machine, the resource manager determines which queue to place the mobile machine, and then generates a queue position and sends a queue position signal to the approaching mobile machine.

Abstract: A method for determining the relationship between the heading of a machine and the course of machine travel is provided. The method includes the steps of determining a previous and current course of machine travel, and a current and filtered heading. An indicator is used to represent the relationship between the heading of the machine and the course of machine travel. The previous and current course of machine travel are compared and the indicator is responsively updated. The current and filtered heading are compared and the indicator is again responsively updated, and then the filtered heading is updated.

Abstract: The present invention is directed towards an apparatus for filtering particulate matter from a fluid. The apparatus is adapted to be placed within a bore of a housing, and in the preferred embodiment comprises a body member having a first end portion, a second end portion, and a middle portion disposed between the first and second end portions. A first flange and a second flange are connected to the first end portion. A third flange and a fourth flange are connected to the second end portion. A first fluid passing groove and a second fluid passing groove extend from the first end portion toward the second end portion. The first and second fluid passing grooves define a first web portion. A third fluid passing groove and a fourth fluid passing groove extend from the second end portion toward the first end portion. The third and fourth fluid passing grooves define a second web portion.

Abstract: A digital communication circuit that avoids bit collisions between an external communication device and a controller that communicate to each other through a bi-directional serial communication link is disclosed. The digital communication circuit includes digital circuitry that receives and transmits a digital communication signal. A detection circuit detects when a digital communication signal is being received. And delay circuitry receives the transmitted digital communication signal and responsively produces a delay signal to delay the detection of the received digital communication signal.

Abstract: A method for automatically determining the productivity of an earthmoving machine in real time using an onboard computer. The earthmoving machine operates in cycles having a first portion and a second portion. The earthmoving machine moves in a first direction during the first portion and in a second direction during the second portion. The method includes the steps of detecting the starts of each cycle for a series of cycles, determining a machine parameter corresponding to each cycle, calculating a cycle parameter as a function of the machine parameter, and calculating at least one measure of productivity as a function of the cycle parameter.

Abstract: A method for providing information relating to a machine to a user is provided. The method includes the steps of sensing predetermined events relating to the machine and producing corresponding event signals, delivering the event signals to a remote site, comparing the event signals to a profile of events corresponding to the user, and delivering a notification signal to the user if the event signals match the profile.

Abstract: The invention is an apparatus for determining a valve transform curve in a fluid system. The fluid system has a valve and a fluid actuator arranged to initiate movement of a load. The invention includes a desired velocity manager, a load responsive device, and a valve transform curve manager. The desired velocity manager determines a desired velocity of the load. The load responsive device determines a characteristic of the load, such as weight or position. The valve transform curve manager receives responsively determine a valve transform curve based on the desired velocity and load characteristic.
