Application specific traffic optimization in a wireless link
A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections which conform to a transport layer protocol such as TCP, UDP, and RSTP, and includes wireless links, which transmit packets using a radio frequency (RF) medium. Typical protocols, however, are usually developed to optimize throughput and minimize data error and loss over wired links, and do not lend themselves well to a wireless link. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection. Since certain data types, such as streaming audio and video, are more loss tolerant, determination of the data type is used to compute link control parameters for the wireless link which that are optimal to the type of data being transmitted over the link. |

Memory management for video decoding
Techniques and tools described herein help manage memory efficiently during video decoding, especially when multiple video clips are concurrently decoded. For example, with clip-adaptive memory usage, a decoder determines first memory usage settings expected to be sufficient for decoding of a video clip. The decoder also determines second memory usage settings known to be sufficient for decoding of the clip. During decoding, memory usage is initially set according to the first settings. Memory usage is adaptively increased during decoding, subject to theoretical limits in the second settings. With adaptive early release of side information, the decoder can release side information memory for a picture earlier than the decoder releases image plane memory for the picture. The decoder can also adapt memory usage for decoded transform coefficients depending on whether the coefficients are for intra-coded blocks or inter-coded blocks, and also exploit the relative sparseness of non-zero coefficient values. |

Method for secure single-packet authorization within cloud computing networks
A method for secure single-packet authorization and secure transparent access to software services residing on cloud-based servers other than the host system where the SPA server itself is running. A single packet authorization (SPA) server running on a host system passively monitors a network for a valid SPA packet while maintaining a default deny stance on a gateway packet filter. The SPA server stores the MD5 sum of every valid SPA packet that it monitors and flags any duplicate access attempts. This way, if any SPA packet has the same MD5 hash as a previously monitored packet the SPA server treats the packet as malicious. After a valid SPA packet is sent, the SPA host server provides a Network Address Translation (NAT) which essentially creates an “SPA gateway” within a Cloud network independent of any other border gateway devices that already exist within the Cloud. The client system may then request access via the SPA gateway to services that are on other Cloud systems besides the one where the SPA server is running. |

Absorber for terahertz radiation management
A method and apparatus for minimizing the degradation of power in a free electron laser (FEL) generating terahertz (THz) radiation. The method includes inserting an absorber ring in the FEL beam path for absorbing any irregular THz radiation and thus minimizes the degradation of downstream optics and the resulting degradation of the FEL output power. The absorber ring includes an upstream side, a downstream side, and a plurality of wedges spaced radially around the absorber ring. The wedges form a scallop-like feature on the innermost edges of the absorber ring that acts as an apodizer, stopping diffractive focusing of the THz radiation that is not intercepted by the absorber. Spacing between the scallop-like features and the shape of the features approximates the Bartlett apodization function. The absorber ring provides a smooth intensity distribution, rather than one that is peaked on-center, thereby eliminating minor distortion downstream of the absorber. |

Light-emitting element with multiple light-emitting layers having controlled carrier mobility and lighting device and electronic device using the same
Disclosed is a light-emitting element which includes a first light-emitting layer over and in contact with a hole-transport layer and a second light-emitting layer over and in contact with the first light-emitting layer. The first and the second light-emitting layers contain a bipolar host material and an emissive guest material. The guest material in the first light-emitting layer has a lower ability for capturing a hole than a guest material in the second light-emitting layer; therefore, the hole-transport property of the first light-emitting layer can be controlled to be higher than that of the second light-emitting layer. The difference in hole-transport property between the first and second light-emitting layers allows a recombination region to be widely spread in the light-emitting layers. An anti-reducing material may be provided in the hole-transport layer, which prevents the hole-transport layer from being reduced by electrons which fail to undergo recombination in the light-emitting layers. |
