Abstract: A method for the degradation of polycyclic aromatic compounds is disclosed that involves dissolving ozone in a bipolar solvent comprising a non-polar solvent in which is of sufficiently non-polar character to solubilized the polycyclic aromatic compounds, and a polar-water-compatible solvent which is fully miscible with the non-polar solvent to form a single phase with the non-polar solvent. The bipolar solvent with dissolved ozone is contacted with the polycyclic aromatic compounds to solubilize the polycyclic aromatic compounds and react the dissolved polycyclic aromatic compounds with the ozone to degrade the dissolved polycyclic aromatic compounds to oxygenated intermediates. The bipolar solvent is then mixed with sufficient water to form separate non-polar and polar phases, the non-polar phase comprising the non-polar solvent and the polar phase comprising the non-polar solvent and the oxygenated intermediates.

Abstract: Methods for updating and recovering user data of a non-volatile memory array such as a flash memory are disclosed. An indication for indicating a mapping relationship for a logical address is established when original user data of the logical addresses is updated into new user data. The indication records new pointers, which record the mapping relationships between logical addresses and physical addresses storing the new user data of the logical addresses. Alternatively, the indication records memory positions of the non-volatile memory array which are defined as designated memory positions and a sequence for using these designated memory positions.

Abstract: Techniques for efficient upconversion can process complex input data, such as for example data in an inphase and quadrature form. Half sample interpolation filtering and delay can be performed, and the results can be combined in a quarter-rate upconverter. The quarter rate upconversion can allow one of the half-sample interpolating filtering and the delay to be performed on one of either the inphase and quadrature samples.

Abstract: Methods and terminals can use Internet Protocol (IP) packets for waveform independent contention access in a hub-spoke network. In some embodiments, a spoke terminal can transmit a link allocation packet on an uplink when the uplink is available and the spoke terminal has data to transmit. The link allocation packet can be embedded within an IP packet. When the spoke terminal receives the link allocation packet on the downlink, the spoke terminal can transmit one or more IP packets with data, followed by a link release packet. The link release packet can be embedded within an IP packet.

Abstract: An automatic document feeder includes a transfer channel, a pick-up module and a thickness detecting module. The thickness detecting module includes a detecting member, a transmission member and an optical displacement sensing member. By the pick-up module, a sheet article is fed into the transfer channel.

Abstract: Disclosed are a multi-layer substrate and a manufacturing method of the multi-layer substrate. By employing a carrier to alternately form dielectric layers and metal structure layers thereon. Each dielectric layer adheres with the adjacent dielectric layer to embed the metal structure layers in the dielectric layers corresponding thereto. Comparing with prior arts, which have to use prepregs when hot pressing and adhering different layers of different materials, the present invention takes fewer processes, thus, fewer kinds of materials without using prepregs. Therefore, the present invention can promote the entire quality and yield of manufacturing the multi-layer substrate to satisfy mechanical characteristic matching of the multi-layer substrate and to reduce cost of the whole manufacturing process.

Abstract: An expandable downhole tool such as an under-reamer or a stabiliser includes a mandrel mounted for linear slidable movement relative to a main body. The mandrel, together with one or more travel blocks, cause movement of a working component in an axial direction. One or more outwardly extending guide paths slidably interact with the working component to cause the working component to move between a withdrawn inoperative position and an outwardly deployed operative position. Upon increase of hydraulic pressure from below the tool, the mandrel is urged against a spring biasing the deactivated position to move axially and cause the working component to take its operative position. Upon decrease of hydraulic pressure, the spring moves the mandrel axially to cause the working component to take its withdrawn inoperative position.

The third lens set is configured to diverge the light to enlarge a full field angle. The negative power reflecting mirror is configured to further enlarge the full field angle and correct image distortion. The first lens set, the second lens set, the third lens set and the reflecting mirror have a common optical axis. The optical axis is shifted with respect to a center of a micro display.

Abstract: Systems and methods for producing ozonated water on demand. In particular, these systems comprise a water source, an ozone source, and a nozzle that mixes ozone and water to form a highly concentrated, ozonated water solution. Instead of requiring the ozonated water to be re-circulated to achieve a desired ozone concentration, the nozzle is configured to form the ozonated water solution in a single pass through the nozzle. Additionally, instead of requiring the ozonated water to be discharged into a pressurized tank to increase ozone absorption, the nozzle allows the ozonated water to be openly discharged. In some cases, the nozzle comprises a venturi with multiple ozone inlets to increase mixing. Additionally, in some cases the nozzle comprises a single pass mixing mechanism that mixes the water and ozone to form the high concentrate, ozonated water solution in a single pass through the nozzle.
