David Duvan 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: 8281871
    Abstract: A system, and a method of using a system, for controlled tool operation. The method includes providing a tool used in a force application such as a such torque application. The tool communicates with a controller which can communicate with the tool, and to a display in communication with the tool and the controller. The controller can be programmed with operational information about a tool operation. Information related to the operational information is displayed to a user during use. Service information including at least information about an amount of force applied during use is recorded and stored in the controller. Also disclosed is a computerized system for controlled tool operation which sends operational instructions to the tool before use and retrieves service information from the tool after use.

  • Patent number: 8171828
    Abstract: An electromechanical wrench has a housing that has a working end and a gripping end, with a driver positioned at the working end, and a handle positioned at the gripping end. The wrench further includes a click wrench emulator mechanism provided at the handle. A method of using an electromechanical wrench to secure a fastener using angular measurement without the need for establishing a zero reference point, and allowing for ratcheting, is also provided. A method of counting the number of fasteners secured by an electromechanical wrench during a wrenching job is further provided.

  • Patent number: 7107884
    Abstract: An electronic torque wrench has a tubular core with elongated apertures therein which respectively removably receive user interface assembly and power assembly modules, the modules being exposed through openings in a surrounding grip sheath. A workpiece-engaging head is coupled to a beam member which may received in a tapered opening in a shim member received in an end of the tube. A sensor on the beam member is connected by wires extending to the user interface assembly, which in turn has a display device producing a bar graph display indicating the proximity of a measured torque value to a preset torque level.

  • Patent number: 6968759
    Abstract: An electronic torque wrench has inner and outer telescoping housing portions and a battery tray assembly telescopically receivable in the inner housing portion and a bezel assembly receivable in an aperture in the outer housing portion and interconnected with the housing portions and the battery support assembly by a single fastener. The bezel assembly carries torque measuring circuitry including a microcontroller, and a four-key pad including arrow keys for incrementing and decrementing a preset torque level at any time, an on/zero key and a units key for toggling among plural different units of torque measurement. The preset torque level is displayed until torque is applied or a key is pressed and can be changed and displayed at anytime.
