Abstract
A method and apparatus for optical imaging and assessment of tong cassette positioning devices, including identifying a focus area on a tong cassette; optically imaging the focus area with an optical imaging device on a positioning device; and analyzing information from the optical imaging to determine an assessment of the focus area. A system includes: a tong cassette having a focus area; a positioning device having an optical imaging device to image the focus area; and an analyzing device functionally connected to the optical imaging device to receive information therefrom.
Claims24
A method comprising:
- identifying a focus area on a tong cassette coupled to a tong;
- optically imaging the focus area using an optical imaging device on a positioning device;
- analyzing information from the optical imaging to determine an assessment of the focus area;
- and
- causing action based on the analyzing, wherein the action comprises at least one selected from the group of extending arms of the positioning device, connecting the positioning device to the tong cassette, and locking the tong cassette in the arms of the positioning device.
(canceled)
A system comprising:
- a tong cassette having a focus area, wherein the tong cassette is coupled to a tong;
- a positioning device having an optical imaging device configured to image the focus area;
- an analyzing device functionally connected to the optical imaging device to receive information therefrom;
- and
- an actuator capable of receiving commands from the analyzing device.
(canceled)
An optical imaging and assessment system for use with a positioning device and a tong cassette, the system comprising:
- an optical imaging device located on the positioning device;
- a tong coupled to the tong cassette;
- a focus area on the tong cassette, wherein the optical imaging device is positioned to capture an optical image of the focus area;
- and
- a local controller located on the positioning device and functionally connected to the optical imaging device.
