摘要:
A permeable structure forms a chamber to hold living cells. The structure includes a first permeable region surrounding at least a portion of the chamber having a conformation that, when implanted in host tissue, substantially blocks penetration of host cells into the chamber while permitting solute transport. The structure also includes a second permeable region overlying the first permeable region having a conformation that, when implanted in host tissue, forms a permeable interface with host tissue that permits solute transport. A third permeable region is located between the first and second permeable regions. The third region comprises a solution of polymer material formed in place between the first and second permeable regions. The third permeable region bonds the first and second permeable regions together. The third permeable region also has a conformation that, when implanted in host tissue, permits solute transport between the first and second permeable regions. The third, formed-in-place region bonds the first and second permeable regions together, providing a robust, laminated structure that resists delamination during implantation caused by cellular infiltration into discontinuous spaces between the first and second regions. The third, formed-in-place region can also have a conformation providing an immunoisolation effect. Furthermore, the permeability of the third, formed-in-place membrane is sufficient high that it does not adversely effect the permeability value desired for the overall multiple layer membrane structure.

An implant assembly and methods for loading implant devices which avoids the accidental deposition of transplanted material or other contaminates on the exterior of the device during transportation, storage, and handling are disclosed. The implant assembly of the invention may be used with a large variety of implant devices for implanting a variety of materials such as cells, tissue or other materials into a host. The implant assembly includes an implant device having an elongated port and a first chamber for holding material for implantation and a container with a second chamber for holding the implant device. The container functions to maintain the sterility and protect the physical integrity of the implant device during loading, storage, cryopreservation and transportation and is removed immediately prior to implantation of the device. The container may optionally include liquid media for cellular growth, maintenance, cryostorage, or transportation purposes.

An apparatus, system, and method to flash print an image. The apparatus includes an energy source that delivers energy. The apparatus includes an energy pulse width modulator coupled to the energy source. The energy pulse width modulator may receive energy from the energy source and modulate the energy received from the energy source. The energy pulse width modulator may be driven by a logic module. The apparatus also includes a plurality of imaging pixels modulated by the energy pulse width modulator and conveying modulated energy to a host material. The host material may be in close proximity to a receiving medium and the modulated energy may release dye from the host material into the receiving medium.

An electrically insulating valve includes a body housing a valve mechanism. The body has first and second openings in communication with the valve mechanism. The body is adapted to attach to a first pipe so that the first opening is in communication with the first pipe. An electrically insulating insert having a passage there through is connected to the body so that the passage is in communication with the second opening. The electrically insulating insert is also adapted to be attached to a second pipe.

A content capability clearing house that can act as a trusted and neutral mediator among network providers to manage rich content capabilities among multiple networks is provided. Content capabilities that can be brokered include, but are not limited to, quality of service and content screening. In an embodiment, a content capability clearing house includes a receiver that receives content capability request messages and other messages from network providers. A content capability request message includes a quality of service request and/or a subscriber profile request for use with content screening and subscriber specific advertisements. The present invention includes a series of methods for determining content capabilities for data transmission over a transaction between a content provider and a subscriber in which a content capability clearing house is used to efficiently broker and manage the capability among multiple network providers.
摘要:
A system and method are described whereby interoperability is facilitated in a 3GPP network environment in combination with DIAMETER policy controls. Such interoperability enables updated policy rules to be fully communicated in on-line charging situations where quota expirations occur. This invention maintains centralized policy control in a 3GPP network with on-line charging.

A billing mediation system for use within a communications network that correlates session records pertaining to usage of network resources is disclosed. The billing mediation system includes a record receiver, a record correlator, a look ahead cache, a set of buffers, and a session records database. The set of buffers includes a single segment insert buffer, a multi segment insert buffer, a multi segment update buffer and a billing finalization update buffer. A method for correlating session records is also provided. The method includes receiving a session record, placing the session record into a segment buffer based on the type of record, and updating a look ahead cache including providing a timestamp for the last update for a session. The transfer of correlated session records to a billing system is based on whether records for a session have been received based on session tracking within the look ahead cache.

Containers and components thereof for use in the medical industry and methods to manufacture the same are described. An example tab for use with a medical container includes opposing sheets sealed to define an open ended chamber into which a port is to be at least partially positioned. The port is to enable access to the medical container. The tab includes a tear seal defined by each of the opposing sheets and a first guide positioned on a first side of each of the tear seals. The tab includes a second guide positioned on a second side of each of the tear seals, wherein the first and second guides are to enable a tear to propagate substantially between the guides and adjacent the tear seals.
