An in-camera two-stage compression implementation is described that reduces the latency between snapshots to a fraction of that otherwise required by other systems that either process complete compression following each snapshot or that incorporate heavy, bulky, and expensive RAM hardware capable of maintaining several raw luminosity records (unprocessed file containing a digital image). In the 1st stage compression the raw luminosity record is quickly, yet partially, compressed to available RAM buffer space to allow a user to expeditiously capture a succeeding image. When the higher-priority processes, the user shooting pictures, and stage one compression subside, a 2nd stage compression, which is slower but more effective, decompresses the earlier partially-compressed images, and re-compresses them for saving in flash memory until they are distributed to a remote platform to be finally converted to the JPEG2000 format.

A mobile terminal for use in a cellular communications network the terminal being adapted to: i) if the terminal transmits signals at a power below the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a first scheme; and ii) if the terminal transmits signals at a power exceeding or about to exceed the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a second scheme different from said first scheme.

A pouch-type lithium secondary battery including: an electrode assembly; and a case to house the electrode assembly, including first and second case portions. The first case portion includes a receiving part to receive the electrode assembly, and a wing part extending from the receiving part. The second case portion includes an outer part that is sealed to the wing part, and an extension part that extends from the outer part and is folded toward the wing part.

Optical data signal receiver having an optical separation of the received data signal into two signal paths, namely, an amplitude detection path and a phase detection path, wherein the phase detection path is split into an in-phase signal path generating in-phase-signals and a quadrature-signal path generating quadrature-signals, and both the in-phase-signal path and the quadrature-signal path, as well as the amplitude detection path, are connected to an analysis unit for demodulation of the received data signal, in which a normalizer and thereafter a symbol discriminator and a data reconstruction logic are arranged in the analysis unit. In the receiver, a connection is provided at least from the amplitude detection path to the normalizer, the normalizer normalizing the in-phase and quadrature-signals with the aid of the signal output from the amplitude detection path, the symbol discriminator discriminating the symbols output from the normalized in-phase and quadrature-signals. Additional connections can be provided from the amplitude detection path signal.

A reduced bitline precharge level has been found to increase the SRAM Beta ratio, thus improving the stability margin. The precharge level is also supplied to Sense amplifier, write driver, and source voltages for control signals. In the sense amplifier, the lower precharge voltage compensates for performance loss in the bit-cell by operating global data-line drivers with increased overdrive. In the write driver, the reduced voltage improves the Bitline discharge rate, improves the efficiency of the negative boost write assist, and decreases the reliability exposure of transistors in the write path from negative boost circuit.

A hybrid transonic-subsonic airfoil is provided that combines subsonic and transonic features for achieving simultaneously acceptable aerodynamic characteristics at low subsonic and high transonic Mach numbers.

A method for manufacturing a composite material including tin oxide particles and a fibrillar carbon material, including synthesising tin hydroxide particles obtained from a tin salt by precipitation/nucleation in a water-alcohol medium, in the presence of the fibrillar carbon material and an acid, the fibrillar carbon material being nanotubes, carbon nanofibres, or a mixture of the two. The method can be used for the production of negative electrodes for lithium-ion batteries.

An autostereoscopic display device comprises a display panel (3) having an array of display pixel elements (5) for producing a display, the display pixel elements being arranged in rows and columns. An imaging arrangement (9) directs the output from different pixel elements to different spatial positions to enable a stereoscopic image to be viewed. The imaging arrangement comprises first and second polarization-sensitive lenticular arrays (50,52), wherein the light incident on the imaging arrangement is controllable to have one of two possible polarizations, and wherein each of the two possible polarizations gives a different 3D mode. These multiple modes can be used to increase the resolution, or increasing the number of views, or provide additional functionality to the display device.

A process for regenerating a facilitated-transport membrane, such as a gas separation membrane, that contains an ionic complexing agent, and that has lost performance as a result of reduction of at least some of the ions to a less charged or uncharged form. The process involves exposing the membrane to an oxidizing agent, such as hydrogen peroxide. The invention also includes membranes that have been regenerated in this way, and their use, particularly for separating light olefins from light paraffins by membrane gas separation.

An air separation method and apparatus in which a supercritical oxygen product is produced by heating a pumped liquid oxygen stream having a supercritical pressure, through indirect heat exchange with a boosted pressure air stream. The indirect heat exchange is conducted within a heat exchanger and a liquid nitrogen stream is vaporized in the heat exchanger to depress the pressure that would otherwise be required of the boosted pressure air stream to heat the pumped liquid oxygen stream. The pumped liquid oxygen stream constitutes 90 percent of the oxygen-rich liquid removed from an air separation unit in which the air is rectified, the liquid nitrogen constitutes at least 90 percent of the liquid nitrogen that is not used as reflux and a flow-rate ratio between the liquid nitrogen stream and the oxygen-rich liquid is between about 0.3 and 0.90.

A centrifugal separator for separating blow-by gases into cleaned air and liquid for recirculation through an engine.

A turbine assembly is provided having a hollow aerofoil having a cavity with an impingement tube insertable inside the cavity and used for impingement cooling of an inner surface of the cavity, and a platform arranged at a radial end of the hollow aerofoil, and a cooling chamber used for cooling of the platform which is arranged relative to the hollow aerofoil on an opposed side of the platform. The cooling chamber is limited at a first radial end from the platform and at an opposed radial second end from a cover plate. The impingement tube is formed from a leading piece and a trailing piece. The leading piece extends in span wise direction at least completely through the cooling chamber from the platform to the cover plate and the trailing piece terminates in span wise direction at the platform.

A turbine assembly having a hollow aerofoil and impingement device, the aerofoil having a first side wall from leading to trailing edge and a cavity arranged a distance to an inner surface of the cavity for impingement cooling and a flow channel for cooling medium from the leading to trailing edge, the impingement device has first and second pieces arranged side by side, the second piece downstream of the first forming a first flow passage providing passage from one side of the aerofoil towards an opposite side. A blocking element is arranged in the flow channel between the second piece and first side wall at a suction side for blocking flow of cooling medium from leading to trailing edge denying access to a section of the flow channel downstream of the blocking element while directing cooling medium in the first flow passage away from the suction side towards pressure side.
