A mechanical joint that resists any direction of imposed force and can be connected in set rotational increments is comprised of three elements: a plug attached to the male-side of the joint, and a receptacle and a tabbed ring attached to the female-side side of the joint. In addition to this, a system mounted on a panel is intended to make higher and more versatile in the functionality. An improved decoder is also provided that reduces the number of bounds checks needed on average for typical compressed data by first guaranteeing that there is sufficient room to decode literals and small substrings, whereby bounds checking is not needed. In the desired installation position, the locking element is in a force-transmitting engagement with a guide mechanism of the actuating rod so as to lock the actuating rod in a position or, alternatively, engages in a formfitting manner with a recess of the guide mechanism of the actuating rod. If authority exists, then an mbean method performs the action on the resource, and filters the obtained results to coincide with the user’s authority. The JRNSO bits may be expanded by using a pseudorandom number generator or a windowing technique.
