A thermoplastic molding composition that contains a polycarbonate resin having specific extensional Theological properties is disclosed. Specifically, the two-position mode selector is operable from outside the housing, and the two-position mode selector is configured to allow the electric strike to selectively operate in a first mode, such as a fail-secure mode, or a second mode, such as a fail-safe mode. The transformer device comprises a magnetic core and a first winding wound around a first axis of the magnetic core. Four MTNCL architectures and four MTNCL threshold gate designs offer an asynchronous logic design methodology for glitch-free, ultra-low power, and faster circuits without area overhead. The invention further provides radiofrequency-activatable inks having customized radiofrequency susceptibility profiles and to sets of such radiofrequency-activatable inks. After the mounting is converted to provide a moveable relationship, however, a temporary temperature excursion can cause the SMA portion to contract, providing a discernible change in the relationship between the sensing element and the body.
