A HEMT-type field-effect semiconductor device has a main semiconductor region comprising two layers of dissimilar materials such that a two-dimensional electron gas layer is generated along the heterojunction between the two layers. A source and a drain electrode are placed in spaced positions on a major surface of the main semiconductor region. Between these electrodes, a gate electrode is received in a recess in the major surface of the main semiconductor region via a p-type metal oxide semiconductor film whereby a depletion zone is normally created in the electron gas layer, with a minimum of turn-on resistance and gate leak current.

A process for making lyocell fibers including the steps of pulping raw material in a digester to provide an alkaline pulp, wherein the raw material includes sawdust in an amount greater than 0% up to 100%; contacting the alkaline pulp including cellulose and at least about 7% hemicellulose under alkaline conditions with an amount of an oxidant sufficient to reduce the average degree of polymerization of the cellulose to the range of from about 200 to about 1100 without substantially reducing the hemicellulose content or substantially increasing the copper number of the pulp; and forming fibers from the pulp.

The present invention provides compositions, useful for making lyocell fibers, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization (D.P.) and a narrow molecular weight distribution. Further, the present invention provides processes for making compositions, useful for making lyocell fibers, by contacting an alkaline pulp having a high hemicellulose content of at least about 7% with an oxidant sufficient to reduce the average degree of polymerization to about 200 to 1100 without substantially reducing the hemicellulose content or increasing the copper number of the pulp.

A method of, system for, and product for managing a denial of service attack in a multiprocessor environment comprising. The first step is establishing normal traffic usage baselines in the multiprocessor environment. Once the baseline is established the next step is monitoring outgoing traffic to detect a high proportion of packets being sent to a specific destination address, and a high number of outbound packets compared to said baseline. Next is monitoring ports and protocols to detect a high proportion of packets sent to a specific port, and a consistent use of a protocol for all packets for that port. If there is such consistent use of a protocol for all packets for that port as to evidence a denial of service attack, blocking measures are started to mitigate the apparent denial of service attack.

The present invention relates to spray-dried amorphous powders which contain a pharmaceutical active substance and a matrix-forming agent, preferably a polymer, sugar or sugar alcohol in an amount of ≧20-60% (w/w). The powders have a moisture content which is less than 1.2% (w/w), preferably less than 1% (w/w). The present invention also relates to special methods of preparing such powders and methods of administering them by inhalation.

A light emitting device comprises at least one solid-state light source (LED) operable to generate excitation light and a wavelength conversion component located remotely to the at least one source and operable to convert at least a portion of the excitation light to light of a different wavelength. The wavelength conversion component comprises a light transmissive substrate having a wavelength conversion layer comprising particles of at least one photoluminescence material and a light diffusing layer comprising particles of a light diffractive material. This approach of using the light diffusing layer in combination with the wavelength conversion layer solves the problem of variations or non-uniformities in the color of emitted light with emission angle. In addition, the color appearance of the lighting apparatus in its OFF state can be improved by implementing the light diffusing layer in combination with the wavelength conversion layer. Moreover, significant reductions can be achieved in the amount phosphor materials required to implement phosphor-based LED devices.

Methods and systems are provided for adjusting a fuel injection split between a direct injection and a port injection based on engine vacuum demand. When more intake manifold vacuum is required, relatively more direct injection is used to take advantage of the associated throttling for generating vacuum. The vacuum may then be used for canister purging, crankcase ventilation, or actuating an engine vacuum consumption device.

The present invention concerns powders containing a pharmaceutical active substance and a combination of excipients comprising at least one 1,4 O-linked saccharose derivative selected from the compounds: 1,4 O-linked D-Gal-saccharose (lactosucrose), 1,4 O-linked D-Glu-saccharose (glucosyl sucrose), or 1,4 O-linked Glu-Glu-saccharose (maltosyl sucrose) in combination with at least one further excipient. The other excipient is preferably an amino acid, a peptide and/or a mono-, di- and/or oligosaccharide, wherein the oligosaccharide may be a second 1,4 O-linked saccharose derivative, provided that this is different from the first.

Communication time period measuring frames are simultaneously sent from an OAM adaptive device on a transmission side, to both a working path and a protection path. In an OAM adaptive device on a reception side, reception times of the frames having arrived from both the paths are checked so as to measure a time period difference between both the paths. The time period difference is fed back to a logic distance adjustment function of each PON section to determine required communication time periods of the PON sections respectively included in a working system and a protection system. Communication time periods of the working system and the protection system in a packet communication network are arbitrated in order to decrease a packet loss at line switching in a packet relaying network.

A high-intensity light source configuration has a long lifetime and can be modulated at a high rate. The configuration includes a movable member mounted to an actuator; a light-emitting phosphor region associated with the movable member; an input light source that illuminates the light-emitting phosphor region at a spot that is fixed relative to an emitted light output region; and a light source controller controlling the movable member actuator and the input light source. The input light source (e.g., laser) provides high-intensity input light to the illuminated spot, causing the light-emitting phosphor region to emit high-intensity output light. The light-emitting phosphor region is moved relative to the illuminated spot so as to reduce optical quenching and photobleaching, to thereby extend the life of the light source configuration. The phosphor region may emit broadband light and/or may include respective sub-regions having phosphors that emit respective peak wavelengths.
