Abstract: An enterprise network opens a virtual private network tunnel with a data center by sending the data center a data request that includes a uniform resource identifier. The data center responds by sending the enterprise network ongoing reply data. A user wishing to access network data of the enterprise network transmits an access request to the data center. The data center authenticates the identity of the user and transmits the access request to the enterprise network. The enterprise network responds to the access request by performing acts upon the network data and/or by returning network data to the data center such that the user is enabled access to the network data. In an alternative embodiment, the data center caches a copy of network data to be retrieved by a remote user when the same network data is disconnected from the enterprise network.

Abstract: Methods and systems for enabling a user to create a user-defined map of an Internet document to control how text and links of the Internet document are presented to the user. A user selects and names regions of text or links of an Internet document to create a user-defined map. A user accesses a voice browser which provides an audio representation of the Internet document based on the user-defined map. Prompts assist a user in creating and navigating through the user-defined map. User requests cause an audio representation of the text or links associated with the user-defined map to be played to the user. When selected content associated with the user-defined map is modified then the updated content is provided to the user.

Abstract: A high pressure stream of natural gas is treated to remove ethane and higher boiling point hydrocarbons and to produce a low pressure stream of pipeline gas and a high pressure stream of pipeline gas. The method comprises the steps of:(a) passing at least a portion of said high pressure stream of natural gas sequentially through:(1) a first heat exchanger where said stream of natural gas is cooled,(2) a Joule-Thompson valve where said stream of natural gas is expanded adiabatically and the temperature and pressure of the stream are each reduced sufficiently to cause ethane and high boiling fluids to condense, and(3) a first gas/liquid separator where a stream of low pressure pipeline gas is separated from condensed fluids;(b) withdrawing the low pressure pipeline gas from said first separator and flowing it through said first heat exchanger, where the gas is warmed, and into a pipeline or other suitable collector; and(c) withdrawing the condensed fluids from said first separator.
