  • Publication number: 20070299939
    Abstract: An approach for providing content transmission upon placement of a call on hold is disclosed. A data communications system includes a proxy server that is configured to receive a message from a first client indicating the hold condition of a Voice Over Internet Protocol (VOIP) call with a second client. The system also includes a content server (e.g., music server) that is configured to transmit the content stored therein to the second client in response to a request message from the server.

  • Publication number: 20070036143
    Abstract: An approach provides interdomain traversal to support packetized voice transmissions. A centralized data store, maintained by a service provider, stores one or more user identifiers and an associated directory number. The centralized data store also stores routing information including one or more communication paths corresponding to the user identifier, wherein the routing information includes a data path or a circuit-switched path for establishing a call to the user. In response to a request for establishing the call to the directory number, the data store retrieves the routing information for use to establish the call.

  • Publication number: 20060209794
    Abstract: An approach provides interdomain traversal to support packetized voice transmissions. A request for establishing a voice call is received from a source endpoint behind a first network address translator of a first domain, wherein the request specifies a directory number of a destination endpoint within a second domain. A network address is determined for communicating with the destination endpoint based on the directory number. Additionally, existence of a second network address translator within the second domain is determined. If the network address can be determined, a media path is established between the source endpoint and the destination endpoint based on the network address to support the voice call.

  • Publication number: 20060072542
    Abstract: A method for performing mode-agile communications during a communications session is disclosed. A communications terminal device supporting multiple modes of access is configured to determine when, during a session involving a first mode of access communications, a second mode of access is available and is to be used for subsequent communications for the session. The communications terminal device initiates or controls switchover from one mode of access to another.

  • Publication number: 20050128637
    Abstract: A perpendicular writer of the present invention comprises a main pole connected to two return poles and further includes one or more shorting shields thereby reducing erasure field on double layer perpendicular media. The perpendicular writer may include side shorting shields connecting the first and second return poles thereby modifying the crosstrack field gradient. Additionally, the perpendicular writer may include a top shorting shield modifying the downtrack gradient and may additionally include a bottom shorting shield for further reduction of erasure fields. The distance between the main pole and the shorting shields may be modified to customize the write field gradient.

  • Publication number: 20040027732
    Abstract: A magnetic read head for use in a magnetic data storage and retrieval system is disclosed. The read head is typically a giant magnetoresistive (GMR) spin valve read sensor with a portion of the GMR spin valve read sensor implanted with ions. The implanted ions improve the GMR sensor's sensitivity to changes in resistance by increasing the resistance of inefficient or ineffective portions of the sensor. The invention is also directed to methods of making GMR read sensors.

  • Publication number: 20030026644
    Abstract: A telescoping joint assembly and a method for making a telescope joint assembly 10. The joint assembly 10 has a pair of members 12, 14 which are telescopically engaged. Assembly 10 further includes a resinous, plastic and/or polymer material 16 which shrinkably coats or lines the inner shaft 12 after the inner shaft 12 is heated and exposed to a substantially inert gas, thereby providing a relatively durable and substantially “low friction” bearing or surface 18 which is effective to promote and/or assist the telescopic sliding motion between the members 12, 14.

  • Patent number: 6126648
    Abstract: An absorbent article includes a moisture barrier, a bodyside liner bonded to the moisture barrier, and an absorbent structure disposed between the bodyside liner and moisture barrier. Elasticized bumpers which function as three-dimensional physical barriers to liquid movement are disposed in the margins of the article. The elasticized bumpers include an internal barrier structure and an elasticized cover disposed over the internal barrier structure and bonded to one of the margins. In particular embodiments, the elasticized cover is formed of a hydrophobic material, is unadhered to the internal barrier structure, and/or is comprised of elastic strands of variable degrees of power.

  • Patent number: 5653843
    Abstract: A method of making an absorbent article includes the steps of providing a continuous carrier web having opposite side edges and disposing a continuous absorbent web on the continuous carrier web between the side edges Continuous strands of an internal barrier material are disposed on the continuous carrier web with one of the strands being located between the absorbent web and each of the side edges. The continuous carrier web, absorbent web and strands of internal barrier material forming a continuous in-process composite structure which is transversely cut to form a plurality of individual, in-process composite structures. Each individual, in-process composite structure includes an absorbent structure and a pair of internal barrier structures disposed on a carrier sheet. The method also includes disposing the individual, in-process composite structures on a continuous moisture barrier web, and providing a pair of continuous covers.

  • Patent number: 5172812
    Abstract: A child resistant blister package includes a top sheet of paperboard having apertures. A thermoformed plastic sheet includes blisters which project through the apertures. A sheet of rupturable material closes off each blister. A bottom sheet of paperboard material is peelably laminated to the sheet of rupturable material. The bottom sheet includes a removable strip being defined by a continuous cut and having a pull-tab. The top sheet includes a severable pull tab extension. A tablet in a respective blister is removable therefrom by pressure being applied at a limited region of the blister, along the edge of the blister closest to the pull-tab, to rupture the rupturable sheet material. The tablet is not removable by pressure applied at a region remote from the pull tab.
