Techniques for selectively restarting processes based on API changes are provided. The forceps set is co-used with two loop ligatures formed of braided sutures and transfigured from a surgeon’s knot. The reference delay circuitry includes components configured to provide a capacitive loading on the reference delay path in order to produce a self-compensating effect on the reference delay that causes the reference delay to be less sensitive than the first delay to variation in the performance characteristic. In an implementation, the stop element includes a stop head and a releasable affixing member. The invention also relates to an object such as a craft.
