In a digital payment system, a sequence of random numbers is stored at a payment service. A set of digitally encoded random numbers derived from the stored sequence is issued to the user in return for payment. The tokens are stored in a Carnet. The user can then spend the tokens by transferring tokens to a merchant, for example, to an on-line service provider. The merchant returns each token received to the payment server. The payment server authenticates the token and transmits an authentication message to the merchant. The merchant, payment server and user may be linked by internet connections.

A multiple network protocol encoder / decoder comprising a network protocol layer, data handler, O.S. State machine, and memory manager state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine which decodes network protocols such as TCP, IP, User Datagram Protocol (UDP), PPP, and Raw Socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler which consists of data state machines that decode data formats such as email, graphics, Hypertext Transfer Protocol (HTTP), Java, and Hypertext Markup Language (HTML). Each data state machine reacts accordingly to the pertinent data, and any data that are required by more than one data state machine is provided to each state machine concurrently, and any data required more than once by a specific data state machine, are placed in a specific memory location with a pointer designating such data (thereby ensuring minimal memory usage). Resulting display data are immediately passed to a display controller. Any outgoing network packets are created by the data state machines and passed through the network protocol state machine which adds header information and forwards the resulting network packet via a transport level mechanism.

A shape-based layout beautification operation can be performed on an IC layout to correct layout imperfections. A shape is described by edges (and vertices) related according to specified properties. Each shape can be configured to match specific layout imperfection types. Corrective actions can then be associated with the shapes, advantageously enabling efficient formulation and precise application of those corrective actions. Corrective actions can include absolute, adaptive, or replacement-type modifications to the detected layout imperfections. A concurrent processing methodology can be used to minimize processing overhead during layout beautification, and the actions can also be incorporated into a lookup table to further reduce runtime. A layout beautification system can also be connected to a network across which shapes, actions, and IC layout data files can be accessed and retrieved.

A TCP / IP processor and data processing engines for use in the TCP / IP processor is disclosed. The TCP / IP processor can transport data payloads of Internet Protocol (IP) data packets using an architecture that provides capabilities to transport and process Internet Protocol (IP) packets from Layer 2 through transport protocol layer and may also provide packet inspection through Layer 7. The engines may perform pass-through packet classification, policy processing and / or security processing enabling packet streaming through the architecture at nearly the full line rate. A scheduler schedules packets to packet processors for processing. An internal memory or local session database cache stores a TCP / IP session information database and may also store a storage information session database for a certain number of active sessions. The session information that is not in the internal memory is stored and retrieved to / from an additional memory. An application running on an initiator or target can in certain instantiations register a region of memory, which is made available to its peer(s) for access directly without substantial host intervention through RDMA data transfer.

A method for efficiently sending notifications over a network. A client system requests to be notified when an event occurs. A server system receives the requests and monitors for the occurrence of the event. When the event occurs a single packet using a connectionless protocol (such as User Datagram Protocol) is sent to the client to notify the client of the occurrence of the event. Using a connectionless protocol to send notification reduces the overall amount of data on the network and thus reduces network congestion and the processing capacity of the server and client. When the client system receives notification an attempt to establish a connection using as connection-oriented protocol is executed. Additional data associated with the occurrence of the event is transferred over the connection. The server may repeatedly send notification using a connectionless protocol until a connection using a connection-oriented protocol is established. The server may send notification that notifies the client of the occurrence of multiple events simultaneously within a single packet. The server may also notify multiple applications of the occurrence of an event using a single notification.

The system provides a coupon-less way for merchants to provide incentive discounts to enrolled customers.

Arbitration of multiple transponders, such as RFID tags, occurs in an interrogation field. The arbitration process is custom-tailored for individual applications, under software control, by the transponder reader or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based upon the tag ID and the transmission cycle number. The tag reader may send a special fast read command to the tag which includes a read request and communications control parameters including the number of time slots for transponder communications, the number of transmissions that an individual transponder is allowed to issue, and the data rate at which the reader communicates to the transponder. The tag reader may also send a special command to a tag to read its data and cause the tag to become decoupled from the environment. Additional schemes are provided to halve the number of active tags in each transmission cycle and to selectively inactivate designated groupings of tag, thereby improving discrimination of the tags in the interrogation field. The tags may be selectively placed in either a tag-talk-first mode or a reader-talk-first mode.

Traditional networked file systems like NFS do not extend to wide-area due to network latency and dynamics introduced in the WAN environment. To address that problem, a wide-area networked file system is based on a traditional networked file system (NFS / CIFS) and extends to the WAN environment by introducing a file redirector infrastructure residing between the central file server and clients. The file redirector infrastructure is invisible to both the central server and clients so that the change to NFS is minimal. That minimizes the interruption to the existing file service when deploying WireFS on top of NFS. The system includes an architecture for an enterprise-wide read / write wide area network file system, protocols and data structures for metadata and data management in this system, algorithms for history based prefetching for access latency minimization in metadata operations, and a distributed randomized algorithm for the implementation of global LRU cache replacement scheme.

An illustrative embodiment of the present invention supports the transmission of data to a user on an as-needed basis over multiple allocated data channels. Data packets are transmitted in time-slots of the allocated data channels to corresponding target receivers without the need for explicitly assigning particular time-slots to a target user well in advance of transmitting any data packets in the time-slots. Instead, each data packet transmitted in a time-slot includes a header label or preamble indicating to which of multiple possible receivers a data packet is directed. The preamble also preferably includes decoding information indicating how a corresponding data payload of the data packet is to be processed for recapturing transmitted raw data.

A system for seismic data acquisition has been invented having, in certain aspects, one or multiple distributed data acquisition subsystems that are independent of energy source controller and / or of navigation system operation. Thus the distributed acquisition system(s) do not require a complicated and burdensome interface to the energy source controller or navigation systems. The seismic data acquisition system supplies a continuous flow of data which is buffered within a centralized data repository for short term storage until required by non-real-time processes. A seismic data acquisition method has been invented that replaces conventional closely coupled interaction between seismic acquisition systems and the energy source controller and the navigation systems by utilizing GPS time stamps on both the data as well as cycling events of the energy source controller and / or navigation systems to insure precise association of seismic data with cycling events. By continuously acquiring data with no interruption in the acquired data flow, association with energy source or navigation events may be accomplished at a latter point in time and not in the real-time operation of the acquisition subsystem.

In a system where a digital still camera 1101 is connected to a printer 1102 on a 1394 serial bus, when the digital still camera 1101 as a data transfer originator node transfers image data to the printer 1102 as a data transfer destination node, the printer 1102 sends information on the data processing capability of the printer 1102 to the digital still camera 1101 prior to data transfer. The digital still camera 1101 determines the block size of image data to be transferred in accordance with the data processing capability of the printer 1102, and sends image data of the block size to the printer 1102. The information indicates the capacity of a memory of the printer for storing print data, or the printing capability of a printer engine, i.e., printing resolution, printing speed and the like. Thus, data transfer is always efficiently performed regardless of the data processing capability of the printer 1102.
