Presented is an air lubricated ship that offers improved efficiency and stability over the prior art. Features of the preferred embodiment of the invention include: 1) a submerged bow that is generally proximal in depth to the stem, 2) a hydrofoil at the bow that not only adds stability but also allows the pressurized air layer(s) to extend further forward under the hull thereby reducing wetted area friction, 3) use of more than one air layer in series which is generally accomplished by water deflecting steps at the air layers forward portions, 4) special positioning of propulsors so that they do not interfere with the air layer(s) by aspirating pressurized air from the air layer(s), 5) optional outrigger hulls to aid to stability and to also increase useful deck area, and 6) optional configurations that allow for use of more than one air lubricated hull where such hulls are connected by structure in catamaran or other arrangements.

An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; and a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby, wherein the memory cell is biased into electrical connection with a data contact member which in turn is electrically connected to the data pin. 15. The electronic key according to claim 14, wherein a spring member is positioned within the housing to bias the memory cell. 16. An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; and a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby, wherein the key blank has an opening for mounting the memory cell therein by interference fit. 17. An electronic key comprising: a housing; a key blank having a portion for insertion into a keyway of an electronic lock assembly, the key blank being attachable to the housing; a memory cell positioned within the housing for supplying data relating to the electronic lock assembly intended to be operated by the electronic key; a data pin positioned to extend through an aperture formed in the housing and being electrically connected to the memory cell for transmitting data supplied thereby; and a spring member positioned in the housing to bias the data pin to an outwardly extended position, wherein the biasing of the data pin to an outwardly extended position maintains contact of the data pin with a data contact pin associated with the electronic lock assembly from its fully extended position to a fully retracted position. arranged in the lower needle cylinder, and, respectively, in the upper needle cylinder; each one of said actuation elements being provided with at least one heel adapted to protrude radially from the corresponding slot of the needle cylinder and being actuatable so as to actuate the overlying or underlying needle; a cam box being arranged around the curved surface of said needle cylinders, said cam box having a plurality of cams that form paths that can be engaged by said at least one heel; said needle cylinders being rotationally actuatable about their own axis with respect to said cam box; wherein at least said lower actuation element comprises a slider that can detachably engage the lower hook of the overlying needle and, below it, a sub-slider provided with an actuation element that has two heels, an upper one and a lower one, which are mutually spaced along an extension of, and parallel to the axis of the needle cylinders; said actuation element being able to oscillate on a plane that passes through the axis of the needle cylinders in order to assume a first position, in which said lower heel is fully contained within the corresponding slot and the upper heel is extracted from the corresponding slot, or a second position, in which said lower heel is extracted from the corresponding slot and said upper heel is fully contained within the corresponding slot, or a third position, in which said lower heel and said upper heel are both fully contained within the corresponding slot; actuation means being provided which act on said actuation element for its transfer into one of said positions; said plurality of cams of the cam box comprising a first set of cams, which define paths for said lower heel for the actuation of said sub-slider and of the overlying slider in the transfer of the corresponding needle from the lower to the upper needle cylinder and in knitting processes with an alternating motion of the cylinders about their axis, and a second set of cams, which define paths for said upper heel for the actuation of said sub-slider and of the overlying slider in the actuation of the corresponding needle in the formation of drop stitches, in the formation of tuck stitches, and in the transfer of the needle from the upper to the lower needle cylinder. 2. The machine according to claim 1, wherein said first set of cams defines a path for said lower heel in order to actuate the sub-slider and the overlying slider when the corresponding needle is arranged in the upper needle cylinder. 3. The machine according to claim 1, wherein said actuation means comprise selection devices for the passage of said actuation element into said second position or into said third position. 4. The machine according to claim 1, wherein said actuation means comprise pressers adapted to interfere with said actuation element for its transfer to said first position or to said third position. 5. The machine according to claim 4, wherein said pressers are movable on command toward said needle cylinders in order to interfere with said actuation element or away from said needle cylinders in order to avoid interfering with said actuation element. 6. The machine according to claim 4, wherein said pressers are fixed and are constituted by portions of said cams that are shaped like inclined planes. amics 5, pp. 99-123 (1972).
