Patents by Inventor David Catto

David Catto has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8910311
    Abstract: A probe assembly is for use in a scanning probe microscope. The probe assembly includes a carrier having a plurality of at least three substantially identical probes, each probe having a tip that is located on a plane that is common to the plurality of probe tips and that is movable from this plane. The assembly also includes addressing means adapted to select one of the plurality of probes for relative movement with respect to a majority of the remainder of the probes. Such an assembly, with its potential to facilitate rapid, perhaps automated, replacement of a used probe, lends itself to use in high-speed scanning apparatus.
    Type: Grant

  • Patent number: 8732861
    Abstract: A control system 32, 75 is for use with a scanning probe microscope of a type in which measurement data is collected at positions within a scan pattern described as a probe and sample are moved relative to each other. The control system is used in conjunction with a position detection system 34 that measures the position of at least one of the probe and sample such that their relative spatial location (x, y) is determined. Measurement data may then be correlated with empirically-determined spatial locations in constructing an image. The use of empirical location data means that image quality is not limited by the ability of a microscope scanning system to control mechanically the relative location of probe and sample.
