Abstract: An embodiment of an integrated circuit includes first and second pads, a supply conductor, and a selection circuit. The first pad is coupled to the supply conductor, and the selection circuit is configurable to couple the second pad to the supply conductor. For example, in a low-pin-count integrated circuit, one may select the second pad to be an input/output pad under normal-power conditions, and to be a supply pad under high-power conditions to reduce the voltage drop along the supply conductor.

Abstract: The invention regards stockings or tights which are kept in place by a system resting on the hips and, therefore, do not oblige the wearer to suffer either pressure round the waist, caused by common elastic bands, nor a tight clasping around the thigh. The system resting on the hips (6, 7) allows an equal distribution of the force necessary to keep the stockings in place, which can therefore be worn for a long time since the wearer does not feel any discomfort on the abdomen or the thighs.
