  • Publication number: 20230154809
    Abstract: An implantable device and method of manufacture include a substantially hermetic polychlorotrifluoroethylene (PCTFE) enclosure with closely-spaced wires extending out of the enclosure. The implantable device includes a PCTFE first portion of an enclosure and a PCTFE second portion of the enclosure. The first and second portions are configured to mate with each other to form the enclosure. A plurality of insulated wires extend between the first and second portions of the enclosure. Each of the insulated wires are parallel to each other and separated by less than 150 micrometers (?m) from a neighboring wire. A thermal weld seam of PCTFE is disposed between the first portion of the enclosure and the second portion of the enclosure and conformally adheres around insulation of each wire such that the enclosure is sealed.

  • Publication number: 20230148968
    Abstract: An implantable device and method of manufacture include a substantially hermetic polychlorotrifluoroethylene (PCTFE) enclosure with closely-spaced wires extending through a slit in the enclosure. A method for manufacturing the implantable device includes cutting a slit in a piece of polymer and extending a plurality of insulated wires through the slit. Each of the insulated wires are parallel to a neighboring wire of the insulated wires. The piece of polymer is thermally bonded around each wire of the plurality of insulated wires such that the piece of polymer is sealed around insulation of each wire with a portion of each wire extending through the piece of polymer.

  • Patent number: 6772162
    Abstract: In accordance with methods and systems consistent with the present invention, a lease manager is provided for managing leases between clients and other network services. To use the lease manager, a client enters into a management lease with the lease manager, specifying an amount of time during which the lease manager can manage preexisting leases between the client and network services on behalf of the client. This management includes renewing the preexisting leases with the other network services. Further, the lease manager notifies the client when a lease between the lease manager and the client is near expiration. The lease manager also notifies the client of failed attempts to renew the preexisting leases, as well as the management lease, either with a network service or with the lease manager.

  • Patent number: 6708171
    Abstract: A network proxy is provided that facilitates the integration of orphan services into a network by enabling them to interact with a lookup service that contains an indication of the services that are available on the network. These orphan services typically reside on devices having too little memory to run the components necessary to be integrated into the network. Thus, the network proxy acts as a go between, by registering the orphan services with the lookup service so that clients may access them and by accessing services on behalf of the orphan services. As a result, the network proxy integrates orphan services into the network, when they otherwise would be incapable of doing so.
