An air brake security locking system retains semi-trailers in a fixed position to prevent theft and is connected to an air brake line of the semi-trailer. The HOCL has a lower interface oxide layer and one or more transition metal oxide layers wherein each of the metal layers selected to form a transition metal oxide has an absolute value of free energy of oxide formation less than that of the metal used to make the interface oxide layer. The supports may be used on a flat surface such as a floor or may be mounted on an independently positioned pair of rails for mounting between a mattress and a box spring by means of posts which are removably received in an opening in the crescent shaped supports and adjustably locked in an opening in each rail. The at least two MOS transistors are in a high impedance state by biasing respective control nodes at a turn-off voltage such that their gate-source voltage is between the forward conduction threshold voltage and a null voltage. The slots are offset so the front and rear surfaces of opposite sleeves are coplanar. Through web site requests for geographic information, a central database tracks an Internet user’s traffic on the Internet whereby a profile can be generated.
