  • Calibrating force and displacement sensors of mechanical probes
    Patent number: 7681432
    Abstract: Concepts presented herein relate to a portable device that includes a frame and a fixture for engaging a mechanical probe to be calibrated. The fixture can be a platform of hard material that receives pushing action of the mechanical probe. A displacement sensor senses position of the platform with respect to the frame. An actuator is coupled to the displacement sensor and a controller is coupled to the actuator. The controller operates the actuator to cause the platform to move to a position (as indicated by the displacement sensor), while the force required to cause the displacement is measured with a force sensor.

  • Large signal scattering functions from orthogonal phase measurements
    Patent number: 7671605
    Abstract: The invention measures the X-parameters (or large-signal S and T scattering functions, sometimes called linearized scattering functions, which are the correct way to define “large-signal S-parameters”) with only two distinct phases for small-signals on a frequency grid established by intermodulation frequencies and harmonics of the large-tones, with guaranteed well-conditioned data from which the X-parameter functions can be solved explicitly, without the need for regression, and not limited by performance limits of the reference generator or phase-noise.

  • Solvent supply with correction of piston movement
    Patent number: 7670480
    Abstract: A supply flow path for supplying a solvent is described. The supply flow path includes metering devices each with a piston, the metering devices being adapted for metering the solvent through separate source paths feeding the supply flow path. The supply flow path further includes a control unit adapted for controlling the metering devices' piston movement in accordance with solvent pressure, wherein a variation of the solvent pressure gives rise to a corresponding variation of a solvent volume contained in the supply flow path or a part thereof. The control unit is adapted for compensating for the variation of the solvent volume by corresponding movements or forward or backward displacements of the pistons.

    Patent number: 7668891
    Abstract: A time accumulator is adjustable to provide sufficient calculation time regardless of the clock frequency. The time accumulator includes a first register storing a current time and a second register storing a time increment value corresponding to a multiplier multiplied by an original time increment associated with a clock pulse of a clock signal. The clock signal is divided into computation intervals, in which each computation interval includes a predetermined number of clock pulses equivalent to the value of the multiplier. The time accumulator further includes a summation node for adding the current time to the time value to produce an updated current time each computation interval.
