A light emitting device comprises a first layer of an n-type semiconductor material, a second layer of a p-type semiconductor material, and an active layer between the first layer and the second layer. A light coupling layer is disposed adjacent to one of the first layer and the second layer. In some cases, the light coupling layer is formed by roughening a buffer layer of the light emitting device. The light emitting device includes an electrode in electrical communication with one of the first layer and the second layer through a portion of the light coupling layer.

A method is disclosed that enables the transmission of media and signaling packets in a Proxy Mobile Internet Protocol-based (PMIP-based) network. A mobile access gateway is enhanced to differentiate between different types of packet traffic and to act as a Session Initiation Protocol (SIP) proxy on behalf of a mobile node. For example, the gateway is able to handle quality-of-service-sensitive (QoS-sensitive) traffic such as voice or video media packets differently from QoS-insensitive traffic such as SIP signaling packets. In the case of traffic packets that are not QoS-sensitive, the gateway engages standard PMIPv6 procedure. In the case of traffic packets that are in fact QoS-sensitive, the gateway acts as a SIP proxy for each mobile node attached to it, thereby avoiding tunneling of the packets between the gateway and the mobile node's local mobility anchor, and thereby reducing the amount of delay that affects the packets.

Aspects of a method and system for a method and system for a soft output Nordstrom-Robinson (NR) decoder may include one or more processors and/or circuits that are operable to more efficiently compute cross correlation values for a received soft output word based on a NR codebook in comparison to brute force computation approaches. Log likelihood ratios may be computed for each information bit corresponding to the received soft output word by determining corresponding maximum cross correlation values.

A model for automated item generator of the graphic intelligence test solves the tremendous time consuming problem for manually devising the graph intelligence item. At the same time, the invention can automated generate more complicated, more transformations and better layout graph for intelligence test, which are hard to predict. The model utilizes the 12 branch tree as the expressing pattern of matrix graph item, and 8 branch trees as the expressing pattern of series graph item. The automated generating item methods have been presented, and the difficulty of the item has also been validated with the similarity of the optional answers and difficulties of the rules and complexity of the sub-graph. The best feature of the model is that a big amount of the graph item for intelligence test can be generated at one time by the computer, instead of manually devising the matrix graph or series graph for intelligence test. With the model, the online intelligence test platform can update the test database automatically, thus the intelligence and the ability of the examinee can be evaluated breaking through the barrier of the language, culture and education background.

Video composition techniques are disclosed for processing video information from a plurality of sources to provide a video image having a plurality of rectangular regions. Each rectangular region displays video information from a specific one of the plurality of video sources. The video information from each video source is in the form of an incoming digital bit stream. The digital bit stream from a first video source has a first bit rate, and the digital bit stream from a second video source has a second bit rate where the first bit rate may or may not be equal to the second bit rate. The incoming digital bit streams are fed to a rate matching circuit which converts all incoming digital bit streams to a common bit rate. The output of the rate matching circuit is fed to a synchronization arid multiplexer circuit which places video information from specific digital bit streams into corresponding rectangular regions of a composite video image.
