  • Patent number: 6687341
    Abstract: A communication network for providing customized information content via a telephone. The network includes a database storing a profile of the customized information content, and a server in communication with the database for generating an audio-based interface document of the customized information content based on the profile. The network also includes an AIN in communication with the server and in communication with the telephone. The AIN may include a SSP switch, a service control point (SCP), and an intelligent resource server. The intelligent resource server maps incoming telephone calls to the SSP switch to the audio-based interface document generated by the server.

  • Patent number: 6596606
    Abstract: A method of forming a semiconductor structure which includes a raised source, a raised drain, a gate located between the source and the drain, a first capping layer in communication with at least a portion of the gate and the source, a second capping layer in communication with at least a portion of the gate and the drain, a first portion of a gate oxide region in communication with at least a portion of the gate and the source, a second portion of a gate oxide region in communication with at least a portion of the gate and the drain. The source, the gate, the first capping layer, and the first portion of a gate oxide region define a first gap. The drain, the gate, the second capping layer, and the second portion of a gate oxide region define a second gap. The structure also includes a first junction area located beneath the first gap, the gate and the source and a second junction area located beneath the second gap, the gate and the drain.

  • Patent number: 6331185
    Abstract: Implants and associated delivery systems for promoting angiogenesis in ischemic tissue are provided. The implants may be delivered percutaneously, thoracically or surgically and are particularly well suited for implantation into the myocardium of the heart. The implants are configured to be flexible so that they compress and expand with corresponding movement of the surrounding tissue into which they are implanted. The flow of blood into the implant and pooling of the blood in and around the implant leads to thrombosis and fibrin growth, a healing process that leads to angiogenesis in the tissue surrounding the implant. Additionally, the implants may contain an angiogenic substance or a thrombus of blood, preloaded or injected after implantation to aid in initiating angiogenesis.

  • Patent number: 6196890
    Abstract: A metal yo-yo embodies a construction in which each of the halves of the yo-yo body is formed from a disc and a hub that are made separately and secured to each other in an integral structure. The discs can be die cut from sheet material and may be deformed about the peripheral margin to define a dished configuration. The hub is inserted into the center hole of the disc and the two are assembled together in a swaging operation that constricts the metal of the disc about a portion of the hub. A pair of such yo-yo halves are connected together by an axle assembly that includes a bearing to facilitate extended spin time for the yo-yo. The yo-yo construction and method of fabrication provides substantial economies in the manufacture of metal yo-yos. In another aspect of the disclosure, the inwardly facing surfaces of the yo-yo halves may be formed to define an annular recess that cooperates with the yo-yo string in a manner that affects retrieval of the yo-yo.

  • Patent number: 5970315
    Abstract: The present invention is directed to a process for fabricating a microelectromechanical device from a substrate carrying at least one layer of a non-erodible material laid out to form at least a portion of the microelectromechanical device, at least one layer of an erodible material, and at least one sacrificial layer. The process includes the step of using the layer of non-erodible material as a mask and anistropically etching any of the layer of erodible material not occluded by the layer of non-erodible material. The process also includes the step of isotropically etching the sacrificial layer under at least a beam portion of the microelectromechanical device to free the beam portion of the microelectromechanical device from the substrate.

  • Patent number: 5783263
    Abstract: A metal or alloy nanoparticle is provided which exhibits hysteresis at room temperature having a carbon coating. The nanoparticle has a diameter in the range of approximately 0.5 to 50 nm, and may be crystalline or amorphous. The metal, alloy, or metal carbide nanoparticle is formed by preparing graphite rods which are packed with the magnetic metal or alloy or an oxide of the metal or alloy. The packed graphite rods are subjected to a carbon arc discharge to produce soot containing metal, alloy, or metal carbide nanoparticles and non-magnetic species. The soot is subsequently subjected to a magnetic field gradient to separate the metal, alloy, or metal carbide nanoparticles from the non-magnetic species.
