Abstract: A high electron mobility transistor device including a channel layer, a first barrier layer, and a P-type gallium nitride layer is provided. The first barrier layer is disposed on the channel layer. The P-type gallium nitride layer is disposed on the first barrier layer. The first thickness of the first barrier layer located directly under the P-type gallium nitride layer is greater than the second thickness of the first barrier layer located on two sides of the P-type gallium nitride layer.

Abstract: Monitoring a communication-based system, comprising: communication service supporting XMPP communication with remote devices; device management applications; external, independent monitoring service monitors the communication-based system; XMPP clients; sending and receiving XMPP messages; and analytical component analyzes XMPP messages to determine status of the system, to possibly restart the communication service if the current response time is below a threshold.

Abstract: A planetary gear device includes a housing having a chamber for receiving lubricating member and having an internal gear, a carrier rotatably received in the chamber of the housing and having an output shaft and having a number of openings for rotatably receiving planet pinions. The planet pinions are engaged with the internal gear of the housing, and each includes a bore for receiving an axle, and a number of rollers received between the planet pinion and the axle to act as a bearing device for smoothly attaching the planet pinions on the axles. The planet pinions each has one or two side portions each having one or more slots for filling the lubricating member into the bore of the planet pinion.

Abstract: A system and method provide a mechanism for integrating social networks and for integrating voice communication with social networks. This is accomplished by an automatic importation mechanism that unifies data from multiple social networks without user intervention. A process is used that creates a universal identity for a user and a table for cross-referencing all of the user identities in different social networks. In addition, a process allows users linked in one communication mode may communicate in a second communication mode. The system includes software portions for enabling the method.

Abstract: A high speed computer that permits the partitioning of a single computer program into smaller concurrent processes running in different parallel processors. The program execution time is divided into synchronous phases, each of which may require a shared memory to be configured in a distinct way. At the end of each execution phase, the processors are resynchronized such that the composite system will be in a known state at a known point in time. The computer makes efficient use of hardware such that n processors can solve a problem almost n times as fast as a single processor.
