Patents by Inventor Christopher Alan LIGHTCAP

Christopher Alan LIGHTCAP 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: 9921712
    Abstract: A system for providing substantially stable control of a surgical instrument is provided. The system includes a surgical manipulator for manipulating the surgical instrument and at least one computer configured to identify a first subset and a second subset of interaction geometric primitives associated with a virtual tool; determine, based on the first subset, control forces in a first subspace; and determine based on the second subset, control forces in a second subspace having at least one additional dimension. Control forces in the additional dimension are only determined based on the second subset of primitives, which is different than the first subset of primitives. The computer is further configured to determine a torque to constrain an orientation of the surgical instrument, wherein determining the torque comprises defining a virtual tool normal and a control plane normal and using the virtual tool normal and control plane normal to calculate the torque.

  • Patent number: 9588583
    Abstract: A system for providing substantially stable haptics includes at least one computer configured to identify a first subset and a second subset of haptic interaction geometric primitives for a virtual tool. The computer is configured to determine based on the first subset, haptic forces in a first subspace. The computer is also configured to determine based on the second subset, haptic forces in a second subspace different from the first subspace.
