A search query is received over a wireless network (20), from a mobile device (10), and a response involves obtaining content summaries of search results relating to the search query, preparing a hypertext page for presentation by the mobile device. The page has a number of the content summaries extending over a number of screenviews. The page has an overview and has hyperlinks for intra-page navigation by a user between screenviews of different parts of the page. The page is sent to the mobile device over the wireless network to enable the content summaries to be browsed without requiring one or more further query and response operations across the wireless network. This can reduce the number of query response operations, by providing more information than the conventional one page annotated list, and presenting the information for easier browsing. The user can then download a selected content item over the network.

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.

Methods and apparatuses are provided for accelerating the throughput and or reducing the power consumption of symmetric cryptography algorithms. Certain computations of a symmetric encryption or decryption algorithm are performed during a first phase, the results are saved to memory, and the results are retrieved to encode data during a second phase. If the first phase is implemented while the battery is being charged and the second phase is implemented while the system runs on battery power, the battery life is significantly extended compared to the battery life when all phases are implemented using solely battery power.

A pressurized transport oxy-combustor with different configurations is disclosed. Substantially pure oxygen is fed to the transport oxy-combustor under pressure to combust fossil fuels, generating steam for power generation. The end product is the flue gas containing substantially pure CO₂ after moisture condensation. The low excess oxygen necessary to achieve complete combustion in the combustor is scavenged by adding another fuel so that substantially all oxygen fed to the combustor is completely consumed. The capability to operate the transport oxy-combustor as a circulating fluidized bed combustor at very high solids circulation rates makes it unnecessary to use recycled CO₂ or flue gas as a means to moderate and control the combustion temperature. The temperature in the combustor is effectively controlled by relatively cooler circulating solids that enter the combustion zone. A small amount of CO₂ is recycled for aeration and to convey solids fuel to the combustor.

An artificial field recording voice sample scheme is high in recording cost and long time duration, and an artificial telephone recording scheme voice sample contains channel noises; the voice sample collection method can solve said problems.

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.
