摘要:
The present invention provides for facilitating establishment of communication with Internet protocol version four (IPv4) private addresses of IPv4 nodes of private networks by using Internet protocol version six (IPv6). In one of many possible embodiments, a gateway is configured to connect an IPv4 private address of a private network node with a public network. The gateway is assigned a globally routable IPv4 address. The gateway is further configured to generate a globally routable IPv6 address based on the IPv4 private address of the IPv4 node and the globally routable IPv4 address of the gateway.

Document personalization machines with a mechanism designed to operate as an in-line document puncher/voider. The document personalization machine includes a document personalization mechanism that performs a personalization operation on the document, a document transport mechanism that transports the document along a document path through the document personalization machine and a document punch mechanism that creates a punch hole on the document. The document can be, for example, a card such as a financial (e.g. credit and debit) card, drivers' license, and a national identification document, or another documents such as a passport. A punched hole can, for example, indicate that the document is void, destroy a magnetic stripe, integrated circuit chip or other information storage medium on the document, or provide access for a lanyard, a key ring and the like.
摘要:
A method and apparatus (500) for operating a node within an ad-hoc communication system (100) is provided herein. A single-radio relay node (500) is used to link overlapping piconets operating on different radio channels. All nodes (203-208) within the ad-hoc communication system (100) operate on multiple channels, which differ for each associated piconet (201, 202). When relaying data between piconets, a node's transceiver (505) will be receiving data during a first time period on a first channel (the data transmitted from a first node existing in a first piconet). During a second time period, the transceiver (505) will relay the data over a second channel to a second node existing in a second piconet.

摘要:
A WDM optical communication system is provided that includes a transmitter and a receiver. An optical fiber transmission path couples the transmitter to the receiver. The transmission path includes at least one repeater having an optical amplifier located therein. A dispersion compensator is disposed at an intermediate point along the transmission path. The intermediate point is located outside of the repeater. The compensator includes a wavelength routing device for dividing a signal having a prescribed bandwidth into a plurality of distinct sub-bands. A plurality of output paths is provided for respectively receiving the plurality of distinct sub-bands. The dispersion compensator also includes a dispersion compensating optical element coupled to each of the output paths. Each dispersion compensating optical element substantially compensates for dispersion at a prescribed wavelength within the bandpass of its respective sub-band. A coupler recombining the distinct sub-bands and couples them back onto the optical fiber transmission path.
