摘要： A semiconductor photodiode (18) is formed as a pn-junction between a region (2) of a first conductivity type and a region (6) of a second conductivity type. The region (6) of the second conductivity type is approximately hemispherical. A mini guard ring (8), i.e. a ring of the second conductivity type having a junction depth that is much smaller than the junction depth of the region (6) preferably surrounds the region (6) in order to prevent surface trapping. The photodiode (18) is operated with a high reverse bias so that light falling on the photodiode (18) produces the avalanche effect.

摘要： The present embodiments provide methods for detecting errors and vulnerabilities in software without access to its source code. The method entails extracting functions from dynamically linked applications, determining error return codes and error numbers for the extracted functions, and forming a wrapper using the extracted functions. The wrapper is used to intercept some of the function calls, wherein the intercepted functions are manipulated to fail. The embodiments further relate to an article of manufacture to detect errors. The article of manufacture utilizes an extraction module to extract functions from dynamically linked applications, software to compile error return codes and error numbers for functions, and a wrapper module to form a wrapper with the extracted functions.

摘要： In an Internet Protocol Television (IPTV) system, an IPTV server is configured to receive a request from an IPTV content storage device (CSD) to view a video stream. The IPTV server selects a set of peers for the IPTV CSD, and transmits the set of peers to the IPTV CSD. In the system, a capacity of a fiber to the node (FTTN) switch in a down linking direction is greater than or equal to a sum of a number of simultaneous viewers supported by the FTTN switch plus a number of viewers that receive video streams from peers in the same community.

摘要： When the intensity of visible light is properly modulated, the difference between the modulated visible light and the original visible light is not noticeable to human eyes but detectable to electronic devices. Thus, the modulated visible light may be utilized to form patterns that are only recognizable to electronic devices but not to human eyes.

摘要： A method and system for streaming media objects. A streaming system includes a group of end nodes and at least one core node connected via an overlay network. The end nodes cache segments of media objects and stream the media objects to a client segment by segment. Each end node stores segment indices for locating segments cached on end nodes or a core node in the system. The core node is a dedicated proxy which fetches media objects from a remote media server and streams the media objects to a client when the media objects are unavailable from the end nodes.

摘要： A peer-to-peer communication system in which a peer communicating with a tracker node on a local torrent can locate and download files that are not currently available from other peers communicating on the local torrent. To enable this, the tracker node maintains collaboration information for a list of files. The collaboration information includes, for each file, a list of locations at which a full copy of the file may be located. The list of locations may include active peers, dormant peers and remote tracker nodes. The collaboration information may be obtained from each peer when it joins a local torrent. Upon joining the torrent, the peer may provide the local tracker node with a list of files that it is willing to serve.

摘要： Methods and systems for supplying media over communication networks are described. In one embodiment, a media supplier determines whether a media object hosted on a web server will be supplied to a client by streaming or not by streaming. Preferably, if the determination is to stream, the media supplier streams the media object to the client. Otherwise, the media supplier preferably allows the host web server to supply the media object to the client. In some cases, the same media supplier may be capable of supplying clients with media objects hosted on any of at least two web servers.

摘要： A method for operating a server having a maximum capacity for servicing requests comprises the following steps: receiving a plurality of requests; classifying each request according to a value; determining a priority for handling the request according to the value, such that requests with higher values are assigned higher priorities; placing each request in one of multiple queues according to its priority value; and dropping the requests with the lowest priority when the plurality of requests are received at a rate that exceeds the maximum capacity. The server operates according to a session initiation protocol.Classifying each request comprises running a classification algorithm. The classification algorithm comprising steps of: receiving a rule set, each rule comprising headers and conditions; creating a condition table by taking a union of all conditions in the rules; creating a header table by extracting a common set of headers from the condition table; extracting the relevant headers from the header table; determining a matching rule; creating a bit vector table; selecting the matching rule according to data in the bit vector table; and applying the rule to place the message in the appropriate queue.
