The tools may also include an input for a head length, when the head of the tool is interchangeable. The tools use the input(s) to calculate a correction factor. The correction factor is used to adjust the torque measurement of the tools so that the tools display the actual torque value without the need for re-calibration or the performance of external calculations. | 11-13-2014 |
| 20140331829 | Method of Calibrating Torque Using Peak Hold Measurement on an Electronic Torque Wrench - The present disclosure relates to an electronic torque tool, a calibration fixture, and a method for calibrating the electronic torque tool. The calibration includes applying a torque to the torque wrench and releasing the applied torque once the applied torque reaches a full scale calibration torque. The calibration fixture holds and displays a peak value of the applied torque and the torque wrench holds and displays a measured peak value of the applied torque. The measured peak value on the torque wrench may then be adjusted, by incrementing or decrementing the displayed value, to match the peak value displayed on the calibration fixture. | 11-13-2014 |
| 20140331830 | Method and System for Instantaneously Logging Data in an Electronic Torque Wrench - An electronic torque wrench is disclosed that instantaneously logs data in real time from a torqueing operation and can later transfer the data to an external device, such as a computer, for further analysis.

The parameters of the graph can be analyzed to determine whether the torqueing operation was performed properly for a particular work piece or job task, or to assist users in future torqueing operations. | 11-13-2014 |
| 20140373690 | TORQUE WRENCH - A top surface of a transmitter on a torque wrench is opposed to a position camera, and bolt holes to fix the transmitter to a wrench main body open on the top surface. The bolt holes are formed to four places so as to define a rectangle and extend in a thickness direction of the transmitter. The marker is attached to the top surface of a head of one of the bolts, which extends through a through bolt hole. When the transmitter is fixed to the main body using a bolt, the depth of a large diameter portion of the through bolt hole is larger than the total thickness of the bolt head portion and the marker. Therefore, the marker is disposed lower than an aperture surface of the bolt hole and the possibility of the marker being damaged during work is reduced. | 12-25-2014 |
