  • System for nano position sensing in scanning probe microscopes using an estimator
    Patent number: 7607343
    Abstract: In accordance with the invention, an estimator is used in the controller portion of a scanning probe microscope to provide precise position estimates of the probe tip which is controlled in the vertical direction by a microelectromechanical system (MEMS) actuator. The precise position estimates typically enhance the ability of the scanning probe microscope to follow the surface and typically provide improved measurements of the surface topography.

  • Digital data signal testing using arbitrary test signal
    Patent number: 7610520
    Abstract: For testing a digital data signal, a value derived from the digital data signal at a sampling point is compared against a corresponding value of an arbitrary test signal.

  • Reducing Noise In Atomic Force Microscopy Measurements
    Publication number: 20090241648
    Abstract: Exchanging data between an Atomic Force Microscopy (AFM) measuring device and an external controlling device using a wireless link. The wireless link replaces cables leading to the AFM measuring device and thereby mitigates mechanical noise vibrations. The controlling device can be an AFM controller, a PC workstation, a keyboard or a pointing device. A power supply and cables to provide power to the measuring device can be replaced with a battery power source to further mitigate mechanical noise. The AFM measuring device can reside in a vibration isolation chamber along with the power source and AFM controller to further isolate noise.

  • Reducing Test Time By Downloading Switching Sequences To An Enhanced Switch Unit
    Publication number: 20090248348
    Abstract: Reducing overall test time taken in modular electronic test equipment via a network by downloading switching sequences of a test sequences to a switch unit. Examples of electronic test equipment networks are PXI, VXI, LXI and GPIB. Latency encountered during communication between a controller and a switch unit can delay the completion of a test sequence. By downloading the switching sequences of the test sequence to the switch unit and allowing the switch unit to control the switching sequences of relays, latency between the controller and the switch unit is greatly reduced. A switching action is incremented with the switch unit receives a trigger signal. The trigger signal can be sent from the controller or the test equipment. The trigger signal can be sent via additional wiring and is independent of the network.

  • Distributing frequency references
    Patent number: 7589595
    Abstract: A correction processor connected to an oscillator uses precision timing signals propagated over a digital network to generate an error signal. IEEE-1588 time synchronization protocols produce precision time signals which are converted to precision interval signals. The correction processor uses the precision interval signals to count pulses of the oscillator. A correction circuit compares the counter output with a predetermined value and generates an error signal may be used to correct the oscillator or may be propagated to consumers of the oscillator. An arbitrary reference oscillator may be used to generate the precision timing signals propagated on the network, to slave other oscillators to it. The precision of the reference oscillator may be deliberately overstated to insure it is used as a master.
