The wheel is equipped with two magnetic sensors having axes of maximum sensitivity lying in a plane that is secant to the axis of rotation of the wheel and which are offset from one another in this secant plane by a predetermined angle ?. As the vehicle moves in a given travel direction, a signal generated by the variation in a magnetic field is measured at the terminals of each of the magnetic sensors to deliver two periodic signals phase-shifted from one another by an angular value equal to (+ or ?) ?, this phase shift is used to determine the direction of wheel rotation, and from such direction and the travel direction, the location, on the right or on the left, of the wheel is deduced.

Abstract: In a vehicle dynamics control apparatus capable of balancing a vehicle dynamics stability control system and a lane deviation prevention control system, a cooperative control section is provided to make a cooperative control between lane deviation prevention control (LDP) and vehicle dynamics stability control (VDC). When a direction of yawing motion created by LDP control is opposite to a direction of yawing motion created by VDC control, the cooperative control section puts a higher priority on VDC control rather than LDP control. Conversely when the direction of yawing motion created by LDP control is identical to the direction of yawing motion created by VDC control, a higher one of the LDP desired yaw moment and the VDC desired yaw moment is selected as a final desired yaw moment, to prevent over-control, while keeping the effects obtained by both of VDC control and LDP control.

In addition, the automatic parking control is cancelled when a steering speed has not yet reached a maximum steering speed with a state where the motor current has reached and remains at the maximum steering speed continuing over a first time period. On the other hand, when a state where the steering speed has reached and remains at the maximum steering speed continues over a second time period, it is determined that there occurs an output shortage of a steering actuator, an automatic parking condition is recalculated, so as to allow the automatic parking continue to continue.

Abstract: In a swather formed by a tractor and attached header for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system acts to calibrate” the control output so that the control module has a secondary reference point as to how the PWM valve should function in the event of a speed sensor failure. Instead of using the speed sensor signal as a reference, the control system now compares the set point with the stored table (which may in one example provide 256 values) containing the PWM voltage/current values. These values correspond to a set of actual speed sensor values taken during the profiling procedure, plus extrapolated values equalling 256 points.

Abstract: The invention allows construction of the architecture of sedimentary layers deposited on a topographic surface as a result of the passage of sedimentary currents, using cellular automata. The topographic surface is discretized into a set of cellular automata. Then, for each current and each automaton, a stationary physical state resulting from an iterative process wherein intermediate physical states are constructed by material and energy exchanges between the automata is determined. These automata are thus constructed so as to be representative of the action of the sedimentary currents on the construction of the sedimentary architecture. A set of geologic variables allowing the architecture of the sedimentary layers to be reconstructed is thus deduced from these stationary physical states. Preferred fields of application of the method are oil exploration and production and reservoir characterization.

Abstract: The state or condition of a system may be evaluated by comparing a set of selected parameter values, converted into a trial vector, with a number of model or exemplar vectors, each of which was represents a particular state or condition of a sample system. Examples of such conditions may include “good”, “marginal”, “unacceptable”, “worn”, “defective”, or other general or specific conditions.

The exemplar vectors are stored in a memory of an operational system. During operation of the system, the trial vector is compared with the exemplar vectors. The exemplar vector which is closest to the trial vector represents a state which most closely represents the current state of the system.

Abstract: Hourglass deformations due to zero-energy or hourglass modes in rank-deficient solid elements must be effectively controlled, or the deformations may grow large and produce an unrealistic deformed geometry. Traditional methods of hourglass control allow error to accumulate by measuring hourglass deformation with incremental terms throughout a solution, which may produce inaccurate results due to unrealistic hourglass deformations. The present invention discloses a new method to control hourglass deformation without any incremental accumulations. Instead the nodal forces to resist hourglass deformations are calculated basing on the initial nodal coordinates and current nodal coordinates at each cycle. The present invention is implemented in a finite element software product.
