Patents by Inventor Christopher Cameron Handford

Christopher Cameron Handford 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: 9024939
    Abstract: A method and apparatus for applying a rotational transform to a portion of a three-dimensional representation of an appliance for a living body is disclosed. The representation is defined by an input plurality of coordinates stored in a processor circuit memory, the input plurality of coordinates representing a general shape of the appliance. The method involves applying the rotational transform to the portion of the representation of the appliance within the transform volume to produce an output plurality of coordinates representing a modified shape of the appliance such that the general shape of portions of the appliance outside the transform volume remain un-modified by the rotational transform, and storing the output plurality of coordinates in the processor circuit memory.
    Type: Grant

  • Patent number: 8576250
    Abstract: A method, apparatus, media and signals for applying a shape transformation to at least a portion of a three dimensional representation of an appliance for a living body is disclosed. The representation is defined by an input plurality of coordinates representing a general shape of the appliance. The method involves identifying a coordinate location of a datum plane with respect to the representation of the appliance, the datum plane defining a transform volume within which the shape transformation is to be applied, the transform volume extending outwardly from and normal to a first surface of the datum plane. The method also involves identifying input coordinates in the plurality of input coordinates that are located within the transform volume. The method further involves modifying the identified input coordinates in accordance with the shape transformation to produce a modified representation of the appliance, and storing the modified representation of the appliance in a computer memory.
