Abstract: A torque applying and indicating wrench is comprised of a pawl with a torque sensing end for both ratcheting, and direct sensing of torque during application. The torque sensing end is bifurcated into a cantilevered flexing beam and an optional reference beam. The flexing beam engages one or more ratchet teeth from a ratchet wheel contained in the wrench head of an elongated tool body. Torque is then transduced and indicated either mechanically or electronically.

Abstract: A portable hard disk drive connector with a parallel (printer) port control board including: a casing including an upper cover and a lower cover engaged with the upper cover; and a control board fixedly fitted in the lower cover and having a parallel (printer) port interface input connector partly protruding out the casing, a parallel (printer) port output connector partly protruding out of the casing, and a hard disk drive connector provided at its both ends with a rack thus forming a U-shaped frame for receiving a hard disk drive.
