Methods and apparatus for key distribution in a conditional access system, assuming that the set of all user nodes which the system can accommodate is a complete set, and a subset is composed of all user nodes or part of user nodes. One method comprises: decomposing said subset into at least one secondary subset; assigning a different user key to each secondary subset, each said user key being transmitted to all users in a corresponding secondary subset; encrypting an entitlement key by using each said user key so as to generate a cipher text corresponding to each said secondary subset; and combining said cipher text to generate a media key control block and transmitting said media key control block to all users in said subset. Since a classification method of a binary tree and a multiple tree is used, the invention can save a lot of network resources.

Disclosed are a method and apparatus for laying down, abandoning and/or recovering a pipe on the sea floor. During lay-down and abandonment, the pipe is lowered by a high capacity winch to an intermediate depth, at which the loading exerted by the pipe has dropped to within the rated capacity of a low capacity winch, to which the loading is then transferred. The high capacity winch line is then recovered to the attendant vessel and the pipe lowered to the sea floor using the low capacity winch. Pipe recovery is essentially a reversal of the above procedure. In this way, the length of the line of the high capacity winch is considerably reduced, which reduces the winch size and hence cost.

Lubricant with non-terminal functional groups. The location of the functional groups minimizes free chain length and molecular weight of a lubricant while simultaneously maximizing evaporation temperature. The locations of the functional groups to the backbone of the molecule of the lubricant allows for shorter lengths of free backbone length between functional groups attached to a lubricated surface. The lubricant lubricates mechanical devices including hard disk drives.

In accordance with an exemplary embodiment of the invention, a substrate of a first conductivity type silicon is provided. A substrate cap region of the first conductivity type silicon is formed such that a junction is formed between the substrate cap region and the substrate. A body region of a second conductivity type silicon is formed such that a junction is formed between the body region and the substrate cap region. A trench extending through at least the body region is then formed. A source region of the first conductivity type is then formed in an upper portion of the body region. An out-diffusion region of the first conductivity type is formed in a lower portion of the body region as a result of one or more temperature cycles such that a spacing between the source region and the out-diffusion region defines a channel length of the field effect transistor.

Crankcase scavenged two-stroke internal combustion engine (1), in which a piston ported air passage is arranged between an air inlet (2) and the upper part of a number of transfer ducts (3, 3′). The air passage is arranged from an air inlet (2) equipped with a restriction valve (4), controlled by at least one engine parameter, for instance the carburetor throttle control. The air inlet extends via at least one connecting duct (6, 6′) to at least one connecting port (8, 8′) in the engine's cylinder wall (12). The connecting port (8, 8′) is arranged so that it in connection with piston positions at the top dead center is connected with flow paths (10, 10′) embodied in the piston (13), which extend to the upper part of a number of transfer ducts (3, 3′). Each flow path through the cylinder and piston is to a great extent arranged in the cylinder's lateral direction, on the one hand in that the connecting port (8, 8′) and adjacent scavenging port (31, 31′) of the cylinder are shifted sideways in relation to each other along the periphery of the cylinder wall (12), and on the other hand in that the transfer ducts (3, 3′) of the cylinder are running essentially in the cylinder's lateral direction away from each transfer port (31, 31′) respectively, i.e. tangentially in relation to the circumference of the cylinder wall (12).

A modular wheel lift provides elevation of a vehicle wheel enclosed by body portions of a low height above the ground. A base lift unit includes a lift surface height selected to be less than the body portions height. A ramp unit is aligned and hingedly attached to one end of the base lift unit, to allow rotational movement of a wheel to the base lift surface. Additional lift units having ramp ends and progressively decreasing lengths are laterally positioned and stacked on the base lift surface. Side brackets are releasably positioned along either side surface to secure the stacked additional lift units to allow rotational movement of the vehicle wheel to an uppermost lift surface. A method of assembly and elevating includes laterally positioning and stacking a plurality of lift units having progressively shorter lengths to provide lifting of a vehicle wheel without disruption of the vehicle body portions.

Lubricant with non-terminal functional groups. The location of the functional groups minimizes free chain length and molecular weight of a lubricant while simultaneously maximizing evaporation temperature. The locations of the functional groups to the backbone of the molecule of the lubricant allows for shorter lengths of free backbone length between functional groups attached to a lubricated surface. The lubricant lubricates mechanical devices including hard disk drives. The lubricant can also be added to media or other mechanical parts in conjunction with other lubricants.

A pelt drying assembly having a pelt board used in the drying of the leather side of a pelt which, in use, is applied to, stretched and secured on the distension element in the stretched position during drying, and a sleeve/bag made of fat and moisture absorbing material for covering the pelt secured in the stretched position by having been drawn over the fur side of the pelt so as to press the pelt against a holding area of the distension element. The sleeve/bag is tubular for drawing onto the pelt board from a pointed end thereof until it covers at least a part of the holding area on the distension element, and has a length equal to at least 1/3, preferably 1/2, of the length of the holding area of the distension element.

A nail appliqué and a method for decorating a natural fingernail or toenail. The nail appliqué generally has a distal end, a proximal end opposite the distal end, a distal decorative portion disposed adjacent the distal end and a proximal decorative portion disposed adjacent the proximal end. The nail appliqué has a length greater than the length of the fingernail or toenail to which the appliqué is to be attached. The distal end has a convex curvature substantially matching the curvature of the cuticle end of the fingernail or toenail to which the appliqué is to be applied and the proximal end has a convex curvature substantially matching the curvature of the distal end such that either the distal end or the proximal end of the appliqué can be applied to the same fingernail or toenail.

A textual information processing apparatus is capable of forming an ink-printed character string and a Braille character string corresponding to input texture information in a common processing area of a tape. The ink-printed character string and/or the Braille character string can be laid out in a desired beautiful fashion. Before performing ink-printing and Braille embossing separately, the Braille embossing area length necessary for the Braille embossing is determined, and the ink-printing area length necessary for the ink-printing is set. The Braille embossing area length and the ink-printing area length are compared with each other, and a greater length is employed as the length of the common processing area.
