  • Adaptive underspeed control
    Patent number: 8175780
    Abstract: A machine (100) includes an engine (102) connected to an implement pump (204) operating an actuator and to a propel pump operating a motor (106). An electronic controller (218) is disposed to receive at least one parameter selected from the group of: a pressure of fluid at the at least one motor (106), a pressure of fluid at the at least one implement actuator, a rate of rotation of the engine (102), a rate of rotation of the at least one motor (106), and a torque output of the engine (102). The electronic controller (218) monitors the at least one parameter for a predetermined period, and determines an operating mode of the machine (100). The electronic controller (218) then adjusts an underspeed setting for the engine (102) based on the operating mode.

  • Method and apparatus for determining a valve status
    Patent number: 6463949
    Abstract: The present invention provides a method and apparatus for detecting a status of a valve, the valve being connected to a fluid circuit. The method includes the steps of establishing an expected value of a characteristic of the fluid of the fluid circuit, determining an actual value of the fluid characteristic of the fluid circuit, and determining a valve status in response to the actual value, and the expected value.

  • Method and apparatus for determining the position of an armature in an electromagnetic actuator using observer theory
    Patent number: 5424637
    Abstract: Electromagnetic actuators that include a coil and an armature are used in a number of applications. It is desirable to determine the position of the armature with respect to the coil without the use of external sensors. Accordingly, an apparatus is provided that determines the position of the armature with respect to the coil in response to the coil current and voltage.
