Claims
- 1. A plug, comprising:
a first base bearing a keyway providing a first electrical conductor and an orifice spaced-apart from and separated by a mass of said plug from said keyway; a second base separated by an axial length of said plug from said first base, said second base bearing means for supporting a cam; an exterior surface extending between and engaging said first base and said second base; locking means responsive to a key inserted into said keyway to accommodate rotation of said plug relative to a cylinder surrounding said plug when the key while inserted into said keyway engages in a selected relation with said locking means and engaging the cylinder absent said selected relation; a second electrical conductor terminating with an electrical contact exposed to an exterior of said first base through said aperture; an electronic logic circuit coupled to receive electrical power and data signals via said first and second electrical conductors, and generating control signals in dependence upon said electrical power and data signals; and an electrical operator having a distal member travelling in dependence upon said control signals between a first position relative to said exterior surface enabling rotation of said plug in relation to a cylinder surrounding said plug and a second and different position relative to said exterior surface obstructing said rotation of said plug in relation the cylinder.
- 2. The plug of claim 1, comprising said locking means, logic circuit and electrical operator simultaneously experiencing said rotation relative to the cylinder whenever said plug rotates relative to the cylinder.
- 3. The plug of claim 1, comprising said locking means, logic circuit and electrical operator being wholly within the cylinder and travelling with said plug whenever said plug moves relative to the cylinder.
- 4. The plug of claim 1, with said electrical operator maintaining said distal member within said plug with said distal member extended not beyond said exterior surface while said distal member is in said first position, and maintaining said distal member in engagement with the cylinder while said distal member is in said second position.
- 5. The plug of claim 1, with said electrical operator maintaining said distal member within said plug with said distal member extending not beyond said exterior surface while said distal member is in said first position, and moving said distal member radially between said first position inside said exterior surface and said second position radially beyond said exterior surface, in dependence upon said control signals.
CLAIM FOR PRIORITY
[0001] This application makes reference to, incorporated the same herein, and claims all benefits accruing under 35 U.S.C. §§119 and 120 from provisional applications entitled Electromechanical Cylindr Plug earlier filed in the United States Patent & Trademark Office on the Sep. 29, 1995 and duly assigned Serial No. 60/004,594, and filed in the United States Patent & Trademark Office on the Feb 12, 1996 and duly assigned Serial No. 60/011,764.
