A serial magnetic mass storage device and associated data storage method of the kind in which data is encoded in single magnetic domains in nanowires. In the invention, the nanowires are provided with a large number of notches along their length to form domain wall pinning sites. Moreover, the notches are addressed in groups (A, B, C) by heating electrodes. By alternately heating the notches hosting head-to-head and tail-to-tail domain walls in synchrony with alignment and anti-alignment of an operating field (H) along the nanowire the magnetic domains are moved along the nanowire by alternate movement of the head-to-head and tail-to-tail domain walls in caterpillar or worm-like motion in which the domains are incrementally lengthened and shortened by one inter-notch distance as they move along the nanowires under the joint coordinated action of the heating and alternating operating field. From an interconnect and fabrication standpoint, the scheme can be scaled almost without restriction out of the plane of the substrate to provide hundreds or thousands of stacked layers of nanowires, thus allowing very dense three-dimensional networks of stored information to be realised.

A method of deploying offshore wind turbine assemblies includes mounting a wind turbine assembly horizontally on a vessel and transporting the wind turbine assembly to an offshore site. The wind turbine assembly is raised to a vertical condition at the site and attached to anchor weights. Blades are attached to the turbine head after the wind turbine assembly is in the vertical condition. In one embodiment, the wind turbine assembly can include a tower including tapered lower and upper sections joined together at their respective wide ends, a turbine head connected to the upper section, and a platform connected to the lower section. The platform includes a buoy tank partially filled with ballast to provide mass and buoyancy. A wave piercing cowling is rotatively attached to the lower section. The turbine head can include an adjustable journal bearing, scabbard blade mounts, and a gearless induction generator with flux adjusting capabilities.

According to the present invention, a rotary blower or supercharger includes a recirculation loop for readmitting pressurized outlet gas back into the rotor chambers, and cooling means for cooling the pressurized outlet gas before it is readmitted into the rotor chambers, thereby providing a supercharger having a lower operating temperature and a higher operating pressure capability. In the preferred embodiment of the present invention, a supercharger includes a housing assembly defining first and second transversely overlapping cylindrical chambers. The housing defines an inlet port for the inflow of an inlet gas, and an outlet port for the outflow of the outlet gas. The supercharger further has first and second meshed, lobed rotors respectively disposed in the chambers for counter rotation about axes substantially coincident with the chamber axes. According to the present invention, the housing further includes a recirculation port and a recirculation flow path for recirculation of a portion of outlet gas flowing out of the outlet port back into cylindrical chamber. The recirculation flow path further including cooling means for cooling of at least a portion of the outlet gas, thereby providing a cooler operating supercharger.

This invention provides a realizing method for two-way increment service based on digital TV one-way set-top-boxes, which takes a digital TV network system finished in two-way reform as the basis to add a blue-tooth module in cable modem, so that a handheld device with the blue-tooth function can communicate with digital TV network system by it to further communicate with the increment service provider server to realize two-way transmission increment service. Since handheld devices with blue-tooth modules and cable modem added with the blkue-tooth module are used in the digital TV system, it is a good solving plan with cheap marginal cost and provides a useful tool for digit life of ordinary families.

The invention relates to a method to efficiently transmit a digital message over a unidirectional optical link, such as the link between a computer screen and a security token equipped with photosensitive elements. It is an object of this invention to provide a source coding scheme that is optimized for transmissions of alphanumerical data containing frequent occurrences of numerals and less frequent occurrences of non-numerical data. This is achieved by using a modified Huffman code for source coding, consisting of a nibble-based prefix-free binary code. The output of the coder is efficiently mapped onto a 6B4T channel code, wherein unused ternary codewords can be used to signal data-link layer events. This efficient signalling of data-link layer events, in turn, allows for a synchronization scheme based on repeated transmissions of a finite-length message, combined with an out-of-band clock signal.
