  • Publication number: 20040123656
    Abstract: A method for correcting data signal errors in a meter has been developed. The method includes receiving ordered data signals from the meter. Next, the sequenced of ordered data signals is analyzed to determine whether a data signal is missing. Finally, if a data signal is missing, a predetermined value is added to a sequence counter to compensate for the missing signal.

  • Publication number: 20040113812
    Abstract: A measuring meter system with communications and features protocols for monitoring the meter has been developed. The system includes a meter that monitors usage of a distribution system, an electronic data recorder that processes data from the meter, and an external unit that controls the processing of data in the electronic data recorder with a communication protocol. The communication protocol includes an initialization signal, an interval identification signal, and a clock signal.

  • Publication number: 20040109527
    Abstract: A method for operating an electronic counter with reduced power consumption has been developed. The electronic counter is divided into multiple segments that are ordered according to their numerical value. As the counter is updated, it becomes necessary to propagate data between the segments. If the supply energy of the counter meets or exceeds a set limit, the data is propagated to the next highest segment. However, if the supply energy of the counter falls below the set limit, the data to be propagated is stored in a propagation carry counter.

  • Patent number: 6612188
    Abstract: The present invention provides for a self-powered fluid meter that uses the kinetic energy of a fluid being measured to provide power for circuitry that may perform functions related to the fluid measurement. An element is placed within a rotating magnetic field created from the kinetic energy of a fluid. This element creates an electrical pulse to power the circuitry.

  • Patent number: 6604434
    Abstract: The present invention provides a device for measuring both the magnitude of rotation of a rotating magnetic field as well as the direction of rotation of a rotating magnetic field. The present invention may be used to measure the magnitude and direction of fluid flow by converting the kinetic energy of a moving fluid into a rotating magnetic field. At least two stationary sensors are placed in the magnetic field to detect the resulting changes in magnetic flux polarity occurring and provide therefrom a determination of the magnitude and direction of fluid flow.

  • Patent number: 6181997
    Abstract: A vehicle suspension system is responsive to an active brake signal from a brake system indicating the application of a greater braking force to one front corner brake than to the other front corner brake to affect vehicle yaw rate. The vehicle suspension system determines the relative velocities of the front corner suspension adjacent the front corner brake receiving the greater braking force and the diagonally opposed rear corner suspension and further determines a compression damping command for the front corner suspension and a rebound damping command for the rear corner suspension. While the active brake signal is present, the suspension control applies the compression damping command for the front corner suspension when its relative velocity indicates that it is in compression. While the active brake signal is present, the suspension control also applies the rebound damping command for the rear corner suspension when its relative indicates that it is in rebound.
