Abstract: A method of coating an internal surface of a tubular member includes: forming a sublayer on the internal surface of the tubular member, the sublayer including a chromium sublayer, a polymer sublayer containing electrically conductive or semi-conductive particles, or a diamond-like carbon sublayer containing an undoped diamond-like carbon material; disposing a hydrophobic layer on the sublayer via a plasma-assisted chemical deposition thereby forming the coating on the internal surface of the tubular member, the hydrophobic layer including a doped diamond-like carbon material, and the doped diamond-like carbon material containing an amorphous diamond-like carbon doped with Si and optionally at least one of F, Co, Cr, W, or Ti.

Abstract: An electronic torque wrench including a wrench body, a wrench head configured to engage a workpiece, a first sensor producing a first output signal, that is proportional to an amount of torque being applied to the workpiece, a grip handle, a second sensor producing a second output signal that is proportional to an amount of rotation being applied to the workpiece, a user interface including an input device for inputting a preset torque value, and a processor for converting the first output signal into a current torque value, comparing the current torque value to the preset torque value, and converting the second output signal into a first angle value through which the workpiece has been rotated after the current torque value exceeds the preset torque value.

Abstract: A torque wrench including a handle attached to a drive member and a transducer that senses the torque transferred from the handle to the drive member and outputs a first signal corresponding to the transferred torque. An analog mechanical input device disposed on the handle that simultaneously defines a set point and indicates the set point. A comparator receives the first signal from the transducer, receives the set point, compares the first signal from the transducer to the set point, and outputs a second signal. The mechanical input device does not display a real time measurement of the torque transferred to the work piece prior to reaching the set point.
