On a local area network, token passing is a channel access method where a signal called a token is passed between nodes to authorize that node to communicate. In contrast to polling access methods, there is no pre-defined "master" node. The most well-known examples are token ring and ARCNET, but there were a range of others, including FDDI (Fiber Distributed Data Interface), which was popular in the early to mid 1990s.

The transaction method is for secure payment by credit cards or debit cards for goods or services with the use or mobile devices. The payment authorization center delivers a public portion of the authorization token to the service provider via the existing communication channels and the private portion of the authorization token is delivered to the mobile device via SMS or USSD or e-mail short message. The mobile device delivers the private authorization token to the service provider via a private local network based on bluetooth, infrared or other short radio frequency based technology. The credit card or debit card number is never revealed and a temporary card token replaces it.

A system and method to ensure that a remote computer making a VPN connection complies with network security policies. Server-driven security checks may be configured to verify compliance with each access level before access is granted at that level. The security checks may be selected based at least according to the information received from the remote computer. After the server determines that the remote computer complies with the security policy for the requested access level, the server may pass a token to the remote computer, or may grant VPN access to the remote computer. If the remote computer does not comply with the security policy associated with the requested access level but is in compliance with a security policy corresponding to a lower access level, the server may grant the remote computer access to the lower access level.

A pipeline video decoder and decompression system handles a plurality of separately encoded bit streams arranged as a single serial bit stream of digital bits and having separately encoded pairs of control codes and corresponding data carried in the serial bit stream. The pipeline system employs a plurality of interconnected stages to decode and decompress the single bit stream, including a start code detector. When in a search mode, the start code detector searches for a specific start code corresponding to one of multiple compression standards. The start code detector responding to the single serial bit stream generates control tokens and data tokens. A respective one of the tokens includes a plurality of data words. Each data word has an extension bit which indicates a presence of additional words therein. The data words are thereby unlimited in number. A token decode circuit positioned in certain of the stages recognizes certain of the tokens as control tokens pertinent to that stage and passes unrecognized control tokens to a succeeding stage. A reconfigurable decode and parser processing means positioned in certain of the stages is responsive to a recognized control token and reconfigures a particular stage to handle an identified data token.

A management server manufactures a secure, tamper-resistant token for a particular user specifying the permissions and authorizations that user possesses. The token may be in the form of a digitally-signed message specifying, for example, a particular computer and associated port number that the user is permitted to access. The management server delivers the token to the user, preferably over a secure communications session. When challenged, the user presents the secure token to the security proxy server. The security proxy server examines the token to be sure it is authentic and has not be tampered with, and then extracts information contained in the token to determine the user's authorization to access a particular computer, particular port number and / or other resource. The security proxy server then establishes authorized communication with the authorized computing resource based on the information contained in the user's token, and thereafter may act in one embodiment as essentially a passthrough or proxy for permitting the user to access and communicate with the resource.

Inter-chip communication system
InactiveUS7512728B2Decrease in performanceMultiple digital computer combinationsCAD circuit designCommunications systemPacket scheduling
The complexity of user designs, the limited capacity of FPGA chips, and the limited number of chip pinouts have resulted in the development of inter-chip communication technology that necessitates the transfer of a large amount of data across a limited number of pins in the shortest amount of time. The inter-chip communication system transfers signals across FPGA chip boundaries only when these signals change values. Thus, no cycles are wasted and every event signal has a fair chance of achieving communication across chip boundaries. The inter-chip communication system includes a series of event detectors that detect changes in signal values and packet schedulers which can then schedule the transfer of these changed signal values to another designated chip. Working with a plurality of signal groups that represents signals at the separated connections, the event detector detects events (or changes in signal values). When an event has been detected, the event detector alerts the packet scheduler. The packet scheduler employs a token ring scheme as follows. When the packet scheduler receives a token and detects an event, the packet scheduler “grabs” the token and schedules the transmission of this packet in the next packet cycle. If, however, the packet scheduler receives the token but does not detect an event, it will pass the token to the next packet scheduler. At the end of each packet cycle, the packet scheduler that grabbed the token will pass the token to the next logic associated with another packet.

Speech recognition system and technique
The present invention relates to speech recognition systems, particularly speech-to-text systems and software and decoders for the same. The present invention provides a decoder for an automatic speech recognition system for determining one or more candidate text unit concatenations according to a predetermined criterion and which correspond to a speech segment, the decoder comprising: means for receiving a sequence of feature vectors corresponding to the speech segment; means for mapping with different likelihood values the feature vectors to sequences of nodes in a decoding network, every sequence representing a concatenation of text units; means for determining one or more candidate node sequences in the decoding network corresponding to the candidate text unit concatenations by implementing a dynamic programming token passing algorithm in which each token corresponds to a node and is associated with a number of text unit concatenations and likelihood values for these concatenations, and wherein a token associated with a node in the decoding network is derived from the tokens associated with the previous nodes in the network; wherein tokens from different nodes that are to be passed to a common node are combined to generate a new token corresponding to the common node and associated with an identifier for text unit concatenations and likelihood values associated with the previous tokens of said different nodes. This is combined with means for merging a said token having a said identifier, the text unit concatenations of the said previous tokens being associated with said merged token dependent on their corresponding likelihood values.

A digital rights management (DRM) system for distribution of digital content such as audio or video uses a token passing scheme to enhance security of the content from unauthorized access and use, including access by unauthorized players. The token is requested from the central content or DRM server by a host device such as a user's computer, using security related information. The token is then passed to a media player associated with the host device, the token being encrypted using a key special to that particular player. Upon receipt of the token, the player transmits back to the server certain related security information confirming receipt of the token and in return receives keys for decryption of the associated digital content. In the absence of proper passing of the token, player access to the content, or further access to other content, is denied. This also allows the player to communicate directly with the server for obtaining the keys.
