  • Publication number: 20040155647
    Abstract: An apparatus and method are provided for sensing the position of a point of contact through use of a sensor having a movable element, disposed between a sensing element and a source of magnetic flux, and having an aperture therein for allowing a portion of the magnetic flux from the source of magnetic flux to pass through the aperture and impinge on the sensing element. The aperture may have various shapes to provide a desired linear or non-linear relationship between the position of the movable element and the intensity of the flux that passes through the aperture and impinges on the sensing element for a given position of the movable element.

  • Publication number: 20040154884
    Abstract: The present invention provides a method and control scheme to operate a motor-driven actuator. This includes determining actuator force on an external device, determining a command force, and monitoring actuator position. A determination is made whether to operate in a force-control mode or a position-control mode. Both the force-control mode and the position-control mode employ a common feedback control method (e.g. PI or PID). The system operates the actuator in the force-control mode, using actuator force as feedback to the control scheme when the controller determines that the force sensor is operating in its linear range. When the force sensor is operating outside or near the limits of its linear range, the control scheme determines a pseudo-force, comprising estimated force based upon measured position. The pseudo-force is input to the common feedback control method to control the actuator.

  • Patent number: 6773336
    Abstract: A method of forming a recess in a body having a surface of substantially cylindrical form utilises a grinding wheel having a first axis in the form of a drive axis, and a circumferential surface concave to a second axis that is substantially orthogonal to the first axis. The grinding wheel also includes first and second opposing radial surfaces of substantially planar form. At least a portion of the circumferential surface of the grinding wheel is engaged with an outer surface of the body and the grinding wheel is rotated about the drive axis to cause a region of the body to be ground, thereby to define a recess in the body having a periphery including at least two substantially square corners and at least one pair of substantially parallel facing edges. The method is conveniently used to provide an opening or port of at least partially square or rectangular form in a cylindrical body such as a metering valve.

  • Patent number: 6774642
    Abstract: A sensor for sensing the angular position of a rotatable body including a stationary transmitter plate with at least one transmitter electrode, a stationary receiver plate with at least a first and a second receiver electrode, and a rotor formed of a dielectric material and positioned between the facing electrodes of the plates. The rotor is smaller than the plates and rotates with the rotatable body to change the capacitance between the transmitter electrode(s) and opposed receiver electrodes. The induced voltages on the receiver electrodes indicate the angular position of the rotatable body. Preferably, the sensor uses a square waveform signal and two transmitter electrodes receive signals 180 degrees out of phase. Then, four receiver electrodes forming two receiver pairs are connected so that the current flowing between each pair is measured and converted to a voltage. A lookup table compares the values of the voltage pairs to known values from calibration, giving the angular position.
