Abstract: In one aspect of the present invention, a contactless inductance switch is disclosed for use with a joystick. The switch is mechanically connected to a mass which is movable between a first and second position. When an operator presses the switch, the mass moves to the second position adjacent to an electrical circuitry. Sensing circuitry measures the change in inductance in the coil and produces a control signal indicating that the switch was pressed.

Abstract: A non-contacting joystick includes a control shaft being universally movable about a Z-axis. A spherical conducting body is attached to an end of the control shaft. A plurality of conducting plates are disposed circumjacent to the spherical body. A charging power supply supplies electrical energy of a first polarity to the spherical body and electrical energy of a second polarity to the plurality of conducting plates. Each conducting plate forms a variable capacitor with the spherical body. The capacitance value of each variable capacitor is a function of the displacement of the spherical body relative to the Z-axis. A circuit produces a plurality of position signals, each position signal being responsive to a capacitance value of a respective variable capacitor. The position signals indicate the relative position of the spherical body.

Abstract: Vehicular and/or walk behind vibratory compactors utilize a vibrated roller or plate to impose compaction forces on a densifiable strata, such as ground soil, a roadway base material or pavement. Utilizing a rotating energy source, such as a engine or hydraulic motor, to create the vibration appears to have reached its limit in the ability to provide a wide range of vibration frequencies and amplitudes to satisfy the ever increasing demands placed on vibratory compactors. Instead of relying upon rotational energy, the present invention contemplates the use of a linear oscillator to produce the vibrations, and preferably utilizes at least one electromagnet to control the frequency(s) and amplitude(s) of a compacting vibration. The present invention finds potential application in a wide range of vibratory compactors, including walk behind models that utilize a plate and larger vehicular models that include one or more vibrating rollers.

Abstract: An apparatus for determining the position of a work implement relative to an earthworking machine. An antenna is mounted to the machine and is oriented to transmit a high frequency signal toward the implement and receive a reflected signal back from the implement. An oscillator is electrically coupled to the antenna and energizes the antenna with electrical energy to generate the high frequency signal. The oscillator produces an output signal having a frequency responsive to the inductance of the antenna. A microprocessor based circuit receives the output signal of the oscillator and responsively determines the position of the work implement relative to the machine. The position of the work implement is a function of the frequency of the output signal.

Abstract: An apparatus for measuring the flow rate of a liquid in a line includes a capacitor formed by a pair of electrodes. A charging circuit produces a charging current of constant magnitude. The charging current is used to charge the capacitor to a predetermined voltage. A timing circuit measures the time between the time at which the charging circuit begins to produce the charging current and the time at which the capacitor has been charged to the predetermined voltage. The timing circuit produces a pulse width modulated signal. The magnitude of the pulse width modulated signal is indicative of the time difference.
