Techniques are described for electrical equipment management. Embodiments include a method for electrical equipment refit management, comprising: receiving a selection of an order of an existing electrical equipment system to disassemble and, in response, retrieving and providing a plurality of disassembly instructions; performing an iterative disassembly process to manage the disassembly of the existing electrical equipment system. A selection of an order of a refit electrical equipment system to assemble is received and, in response, retrieving and providing a plurality of refit instructions; An iterative assembly process is performed to manage the assembly of the refit electrical equipment system. Digital artifacts of the refit electrical equipment system are recorded during performance of the plurality of refit instructions as part of the iterative assembly process. A final assembly report for the refit electrical equipment system and stored together with a unique identifier corresponding to the assembled refit electrical equipment system.

A calibration monitoring system is provided to automatically monitor the calibration status of tools and other inventory items, such as upon the items being issued from or returned to the automated calibration monitoring system. The system identifies an inventory item, for example a calibrated torque wrench or other calibrated tool identified based on a unique identifying tag attached thereto. The system retrieves a calibration parameter value for the item from a calibration database, and completes a calibration measurement of the item based on the calibration parameter value. In the example, a torque measurement of the calibrated torque wrench can thus be automatically completed. In turn, the system determines a current calibration status of the item based on the calibration measurement, and selectively enables or disables issuance of the inventory item from the system according to the item's status as being in calibration or out of calibration.

The present invention relates to torque application tools, such as an electronic torque screwdriver, with a multiple axis gyroscope (such as a 3-axis gyroscope or other type of gyroscope) and torque sensor that allows for simultaneous or sequential measurement of torque and angle around the axis of the tool. Targets for torque and angle measurements may be used to create algorithms to detect breakaway torque, residual torque, or to perform error proofing to ensure unique fasteners are tightened.

An electronic wrench includes a main body, at least one sensing element, a processor and at least one prompting unit. The sensing element is configured to sense a working status of a working head to generate a sensing signal, and the sensing signal includes at least one sensing information value. The processor includes a first prompt lower limit value and a second prompt lower limit value. The prompting unit is configured to provide at least one working status prompt. When the sensing information value is less than or equal to the first prompt lower limit value, the working status prompt is visible in a first numeric display format. When the sensing information value is greater than the first prompt lower limit value and less than or equal to the second prompt lower limit value, the working status prompt is visible in a second numeric display format.

A surface marked threaded fastener comprising an elongated and threaded shaft and a head at one end of the elongated and threaded shaft; said head comprising on a surface contacting face a readable matrix comprising a dot pattern, said dot pattern defining a tightening specification.

The present invention relates to torque application tools, such as a torque screwdriver and ratchet tools, with one or more light indicators disposed in a ring shape around the tool. The light indicators are adapted to indicate amounts of torque values and/or angle values as the tool is used to tighten or install a work piece. For example, the light indicators may flash at a first flashing rate, when about 40% of a target torque or angle value is applied; flash at a second flashing rate (greater or faster than the first flashing rate) when about 60% of the target torque or angle value is applied; and illuminate at a solid state when about 80% of the target torque or angle value is applied.

A communication port interface facilitates charging of a power source, such as a battery, while the power source remains coupled to a tool. The communication port interface also facilitates downloading of torque and/or angle log information from an electronic torque tool to an external device. Torque and/or angle preset job information may be entered in client software and uploaded from the external device to the electronic torque tool via the communication port interface. Additional information including real time clock information and wrench system parameters may be uploaded to the electronic torque tool via the communication port interface.

A torque wrench having post-torque rotation setting and measurement function, optionally including auto transition from torque to angle rotation, which may operation with and without batteries, including low profile design, improved visual, audio and haptic feedback, a recesses pawl seat for improved accuracy and longevity and improved handle rotation for torque setting and spring unwinding by virtue of improved torque setting nut design.

A torque structure includes a first body, a second body, a first elastic member, a retaining unit, an adjusting unit, a mobile unit, and a display unit. The second body has a first guide slot. The first body is rotated relative to the second body to drive the adjusting unit to rotate and move relative to the retaining unit to adjust the torque value. The mobile unit is received in the second body and aligns with the first guide slot. The mobile unit is mounted between the first elastic member and the adjusting unit. The first body drives the adjusting unit which moves the mobile unit which adjusts the compression extent of the first elastic member to adjust the torque value. The display unit display unit detects a position of the mobile unit and indicates a torque value.
