Various embodiments are provided herein for a connector that can provide electrical and mechanical coupling between first and second objects. In a resistance measuring mode, one of the transistors connected to one heating element whose resistance is to measure is turned on, and other transistors are turned off. A method of using the construction frame for installation of doors and windows is also disclosed. A third pivot assembly allows to operatively connect a bottom end of the actuator to the bottom end of the trans-tibial member. The method uses an energy source and a substrate tube, wherein the energy source is movable over the length of the substrate tube between a point of a reversal at the supply side and a point of a reversal at the discharge side. Therefore, it is possible to prevent the second passivation layer formed of an organic insulator from being overetched while etching the insulating layer below the second passivation layer so that the contact hole is prevented from being made excessively wide.
