John 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: 11105703
    Abstract: An apparatus includes a test chamber and a pressure-application structure. The pressure-application structure is configured to apply a force on a device under test within the test chamber in response to a vacuum being drawn in the test chamber. The force has a magnitude that is proportional to a difference between an external pressure outside the test chamber and an internal pressure within the test chamber.
    Type: Grant

  • Patent number: 9999949
    Abstract: An apparatus and associated method are provided for an automated presentment assembly that sequentially feeds fasteners to an outlet and an escapement apparatus comprising a chuck that has a transport feature for selectively removing a fastener from the outlet and transporting the fastener to a tool station, the chuck being moveable between a first position and a second position, wherein at the first position the transport feature is operably aligned with the outlet and at the second position the transport feature is displaced both linearly and rotationally from the first position.

  • Publication number: 20070185616
    Abstract: Method and apparatus for installing a support member to support a flexible element, such a shipping comb used to support a flexible suspension assembly of a head-stack assembly (HSA). A robotic end effector is configured to insert the support member to bias the flexible element. Prior to said insertion, an inspection assembly verifies at least one physical parameter of the member while the member is supported by the end effector. One or more computerized video images along at least one axis are preferably obtained by the inspection assembly, and machine readable code on the member is preferably decoded from said image(s). The end effector preferably includes a pair of opposing gripper fingers which engage the support member with variable compressive force during insertion. A cleaning assembly preferably cleans the support member prior to insertion, and a subsequent video image is preferably obtained after insertion to verify installation of the member.
