Abstract: Diamond-containing articles such as composite materials shaped as some specific article, can be engineered such that bodies that contact the article only contact diamond. In an embodiment, the article may be in the form of equipment for handling semiconductor wafers such as vacuum or electrostatic chucks. In one embodiment, the diamond-containing article can be a composite of diamond particulate reinforcing a Si/SiC body such as reaction-bonded SiC. Lapping the diamond-reinforced RBSC body with progressively finer diamond grit removes some of the SiC/Si matrix material, leaving diamond particles of uniform height “standing proud” above the rest of the surface of the formed article. Further, if the diamond-containing article is sufficiently electrically conductive, it may be machinable using electrical discharge machining.

Abstract: The Federal Communications Commission Order 05-116, E911 Requirements for IP-Enabled Service Providers, (FCC Order) requires interconnected Voice over Internet Protocol (VoIP) service providers to deliver all emergency service calls to a VoIP service user's local emergency service operator as a standard feature of the service. Under the FCC Order, VoIP service providers must supply emergency service if the VoIP service user accesses the VoIP service over broadband and if the VoIP service provider interconnects to and from the Public Switched Telephone Network (PSTN). Embodiments of the present invention guarantee compliance with the FCC Order by routing a call as either a VoIP call over the Internet or as a conventional call over the PSTN, verifying that at least one of the VoIP or PSTN telephony connections supports emergency service and routing calls over that connection or, if there is no connection supplying emergency service, restricting calling over the VoIP connection.

Abstract: A method of managing a repeated surface comprising seismic data as one surface is disclosed where a plurality of horizons is analyzed and a determination made as to which of the plurality of horizons comprise a repeated surface. Those horizons which comprise the repeated surface may then be logically connected into a logically connected horizons data set which may then be assigned a common identifier and which may further respond similarly to a single event, e.g. a user action. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: Authentication of a request for access to user specific information associated with a VoIP device is performed transparently, without any user identification or password required. A unique device identifier associated with the VoIP device is included in the request for access and used as an authentication token.

Abstract: A VoIP analog telephone adapter coupled to a telephone allows a telephone call to be made over the Public Switched Telephone Network (PSTN) or over the Internet. Prior to dialing a phone number, with the telephone “off-hook”, a caller receives an audible indication as to whether the call will be made over the PSTN or the Internet through a standard dial tone generated by a Central Office or a distinctive dial tone generated by the adapter. The distinctive dial tone is different from the PSTN's dial tone.
