Abstract: An electronic torque wrench having a heat-treated hardened steel alloy spacer in a narrowed area of the wrench head. One end of the spacer is secured to one side of the narrowed area of the wrench head. A gap is provided between a free end of the spacer and an opposite side of the narrowed area. During operation of the tool within its rating, the gap remains open. However, when the rated torque is exceeded, the tool will begin to bend, closing the gap and causing the free end of the spacer to contact the adjacent face of the wrench head. The force of any additional torque applied is borne, at least in part, by the hardened torque-limiting spacer rather than by the wrench head.

Abstract: 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.

Abstract: A portable segmented power device (PSP) device having multiple compact interconnected, removable, and independently operable rechargeable battery powered modules, allowing for a user to simultaneously and independently provided power to devices situated at two or more different locations by slipping out one or more compact modular units from the device and carry each compact modular unit to a respective location for safe, convenient, and independent operation.
