Patents by Inventor John William Rigsby

John William Rigsby 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: 7959399
    Abstract: In a robotic assembly, a body adapted for mounting on an arm is provided. A connection is adapted to couple the body and an end effector to allow deflection of the end effector with respect to the body between an open position and a closed position. A conduit allows fluid flow between the body and the end effector. A seal is adapted to engage the conduit to provide a fluid seal when the end effector is in the closed position and allow fluid flow when the end effector is in the open position. Further, end effector deflection can be detected based on the fluid flow and utilized to regulate movement of the robotic assembly.

  • Patent number: 7758364
    Abstract: An apparatus and associated method for rotary positioning is provided in an apparatus having an outer housing disposed around an inner housing, wherein at least one of the housings is rotatable with respect to the other housing. The rotary positioner also has a utility circuit having a first flexible circuit connected at one end to the outer housing and connected at an opposing end to the inner housing and forming a loop therebetween having a first u-shaped bend pointing in a first rotational direction in a space between the housings, and having a second flexible circuit connected at one end to the outer housing and connected at an opposing end to the inner housing and forming a loop therebetween having a second u-shaped bend pointing in a second rotational direction opposite to the first rotational direction in the space between the housings.
