  • Patent number: 6832139
    Abstract: A graphical system configuration program allows material handling systems to easily be defined, configured, and implemented. The system may utilize a computer for configuring an automatic guided vehicle system. Information defining the path layouts for the AGVs, traffic control information, decisional logic for path branches, update marker information, and other information useful for controlling the operation of the automatic guided vehicles may be entered into the computer and displayed graphically. The computer is programmed to automatically verify the validity of the entered information, and to optionally simulate the movement of the automatic guided vehicles. After the information has been validated, it can be converted to a file format that is used by an automatic guided vehicle controller to control the vehicle's movement. Virtually the entire design process for the AGV system can therefore be carried out using a single computer program specifically adapted for that purpose.

  • Patent number: 6832140
    Abstract: Presented are a method and a system by which an individual can obtain usage information of a vehicle. A mobile unit, which may be located inside a vehicle, receives data from a part of the vehicle (e.g., the odometer) and/or Global Positioning System satellites and derives parameters such as the velocity and the travel distance from the received data. Using these parameters, the mobile unit may determine time information such as the amount of time the vehicle is traveling, in idle, or in a parked state within a given time period. Alternatively, the mobile unit may transmit the parameters to a remote computer, which then determines the time information. When a user submits a query requesting a parameter or a mathematical operation on a parameter, either the mobile unit or a remote computer prepares a response and transmits the response to the appropriate user interface.

  • Patent number: 6832143
    Abstract: A control system that senses misalignment of components in a vehicle drive train system and adjusts the vehicle ride height to realign the components. A control unit monitors vibration, torque or other operating parameters of a vehicle's drive train or other vehicle components and determines whether the parameters are abnormal. If the monitored parameters are abnormal, then the control unit controls suspension elements on the vehicle to adjust the ride height of the vehicle and subsequently the alignment of the drive train, for example, the operating angle of the driveshaft. A ride height sensor feeds back ride height measurements as the suspension elements are adjusted to assist in finding an optimal ride height that eliminates or reduces excess vibration and/or torque. In another embodiment, the control unit adjusts the ride height based on vehicle speed or fuel economy to reduce the profile of the vehicle and improve fuel economy.

  • Patent number: 6832149
    Abstract: A valve of an internal combustion engine includes a valve body movable between a fully opened position and a fully closed position, an armature coupled to the valve body, a pair of springs urging the valve body, and a pair of electromagnets. Each electromagnet generates electromagnetic force to attract the armature, thereby moving the valve body. The engine valve is controlled by means of sliding mode. That is, when the valve body is moved from the fully closed position to the fully opened position, the electromagnets are controlled such that the state quantity of the valve body (the position and the moving speed) converges on a previously set switching hyperplane. The switching hyperplane is changed in accordance with the position of the valve body. As a result, a number of factors required for controlling the engine valve are satisfied.

  • Patent number: 6832160
    Abstract: Method for solving the classical inversion problem of finding the angle dependent reflection coefficients along selected reflectors in the subsurface. The input data to the method include seismic constant offset or constant angle data cubes from Pre-Stack Depth Migration of Kirchhoff type and the corresponding reflectors and velocities from the interpretation and velocity analysis of the data. One or more of the reflectors are chosen and ray modeling is done to create synthetic seismics for all shot/receiver pairs in the seismic survey. Based on these modeling results, amplitude correction maps are made for the various reflection angles. These correction maps are applied to the amplitudes from the seismic data. The corrected amplitudes are approximations to the angle-dependent reflection coefficients in all points on each selected reflector. For each point, a weight function is computed, giving the quantitative resolution of the estimate of the reflection coefficient.

  • Patent number: 6832167
    Abstract: The subject of the invention is a method of identification of weak and/or strong branches of an electric power transmission system. In the inventive method electrical parameters characterizing the nodes and branches of an electric power transmission system are subjected to computational treatment in order to obtain equations of power flow in all nodes of the system at assumed 100 percent system load value. Then an electric model of a branch is assumed and a curve P-Q is constructed which shows the functional relation between active and reactive load in the system. For the assumed branch model a branch voltage stability coefficient is determined. Then the analysed system is overloaded by increasing the total system load up to 120% base load and the branch voltage stability coefficient is determined again. The numerical values of the appropriately determined coefficients are compared with threshold values considered to be a safe margin for the maintenance of voltage stability for the given branch.

  • Patent number: 6832171
    Abstract: An internal impedance of a battery (30) is automatically determined by operating a processor (13) to analyze current flowing through the battery to determine if a transient condition due to change of current is occurring and determining when the transient condition has ended. A voltage of the battery is measured while a steady current is being supplied by the battery. The present depth of discharge (DOD) of the battery is determined and a database is accessed to determine a corresponding value of open circuit voltage. The internal impedance is computed by dividing the difference between the measured voltage of the battery and the open circuit voltage at the present DOD by an average value of the steady current.

  • Patent number: 6832173
    Abstract: A testing circuit and method for a phase-locked loop allow measurement of leakage currents in the phase-locked loop components. By forcing the output of the phase-frequency detector to a particular state, the charge pump can be disabled. This disables the effect of feedback in the phase-locked loop, and allowing the output frequency to be determined by the voltage on the control voltage node at the time the feedback is disabled. If there is no leakage, the control voltage, and therefore the output frequency, should remain the same as they were at the moment feedback was disabled. Monitoring the output frequency for changes provides an indication of the presence or absence of leakage.

  • Patent number: 6832178
    Abstract: A multi-sensor system for the real-time embedded monitoring of an object senses mixed-mode object conditions. Various sensors separately provide disparate analog signals representing different measurable attributes regarding the sensed object. For example, such sensors may separately sense temperature, pressure, or other biometric value. Then, according to a specified rule set or other qualifying parameters, a digital signal is generated by a processor or controller to indicate one or more condition of the sensed object according to certain sensor input values. Additionally, such multi-sensor scheme may be coupled to a digital network or otherwise coupled thereto for simulation and/or communication applications.

  • Patent number: 6832179
    Abstract: A signal processor, for use with a zero crossing module of a vortex flow meter, includes a peak amplitude detector, a comparator, and a filter module. The filter module is enabled when the comparator determines that the amplitude is less than a low flow rate threshold. The filter module filters a vortex signal and the filtered signal is provided to a frequency estimator that uses a zero crossing algorithm. The signal processor may increase the signal-to-noise ratio at low flow rates for which the frequency estimator may not otherwise be able to accurately estimate the flow rate. Low flow rates may be measured by determining that there is a low flow rate using amplitude detection of a vortex signal, filtering the vortex signal based on the amplitude detection, and using a zero crossing algorithm on the filtered vortex signal.

  • Patent number: 6832182
    Abstract: An electronic circuit simulator technique dramatically reduces barriers to simulation of complex analog circuits. The simulator technique reduces simulation preparation time by permitting a skilled user to formulate a simulation strategy that can combine a modeling strategy, a deck extraction strategy, and a comprehensive suite of pre-engineered simulation tests that fully characterize a system under test. The simulation technique reduces the CPU time required for each test by allowing a skilled user to encode a device modeling strategy and a deck extraction strategy that effectively minimize the CPU time required to achieve a given simulation objective. For a given simulation objective, a skilled user chooses for each element implemented in a simulation a device model of minimum complexity that achieves a desired level of simulation accuracy and extracts a portion of the complete production schematic that achieves the desired level of simulation accuracy.

    Abstract: A method of requalifying a rail born tank car adapted to transport includes inspecting the tank car in accord with a selected one of a plurality of procedures, each procedure delineating and defining a pre-determined plurality of inspections and test. Inspection data obtained from the predetermined series of steps and tests is input into a computer-readable storage medium, where it is related by a computer having at least one processor, to secondary data, such as ownership data, lease status data, rental status data, and/or transported commodity data. Based on this relation, the computer computes a requalification date for the tank car based on the input inspection data and the secondary data. This requalification date is output to at least one of a computer-readable storage medium, a display device, and a physical print media inclusive of an outer surface of the tank car.

  • Patent number: 6832185
    Abstract: A hardware emulator chip contains an array of cells and a programmable interconnection array. Each cell performs only a single logic function, which is configurable. The chips run asynchronously to one another, and within each chip cells are enabled by a sequential wave signal, which enables successive logical rows of cells. Within the chip, it is possible to connect any arbitrary cell output to any arbitrary cell input. Preferably, a set of off-chip connections is made possible by time-multiplexing the output of each subset to the wave signal. In one embodiment, full interconnection of cells within a chip is provided by providing a time-multiplexed programmable array of interconnect switches, the setting of each switch changing with each successive wave. In a second embodiment, full interconnection of cells within a chip is provided by providing a programmable array of interconnect switches.

  • Patent number: 6832187
    Abstract: Methods of providing page protection in digital printing systems having multiple output devices are described. In one embodiment, first and second output devices are provided and have different time constraints for processing predetermined amounts of data which will ultimately be printed on a print medium. One of the time constraints is selected to provide a selected time constraint, and at least one predetermined amount of data is tested against the selected time constraint to determine whether the selected time constraint is satisfied. If the selected time constraint is not satisfied, the predetermined amount of data is transformed into a state which is more likely to satisfy the selected time constraint. In another embodiment, a first processing time constraint of a first output device is determined. The first processing time constraint impacts the manner in which a predetermined amount of data is processed into a printed image. A second processing time constraint of a second output device is determined.
