    摘要: Polyhydroxyalkanoate (PHA) that contains a pyrogen such as endotoxin due to a process of producing the PHA is treated to remove the pyrogen by a process that does not affect the inherent chemical and physical properties of the PHA to obtain a biocompatible PHA. PHA produced by fermentation with a Gram negative bacteria can be treated with an oxidizing agent such as hydrogen peroxide or benzoyl peroxide to reduce the endotoxin content to less than 20 endotoxin units/gram of PHA to produce PHA that does not elicit an acute inflammatory response when implanted in an animal. The PHA may have a melting point or glass transition temperature less than 136° C., and can be chemically modified or derivatized such as by covalently coupling an attachment or targeting molecule. The PHA may be used to form various medical devices, and can be used for in vivo applications including tissue coatings, stents, sutures, tubing, bone and other prostheses, bone and tissue cements, tissue regenerating devices, wound dressings, drug delivery, and for diagnostic and prophylactic uses.

    摘要: An interoperability system abstracts the protocols used by multiple network applications into an interoperability framework, thereby allowing the network applications to interoperate with each other and/or with modules for providing enhanced functionalities. The interoperability framework includes a number of adapters that modularize the components needed for interoperation and abstracts content from the underlying protocols and procedures used by the network applications. The interoperability framework includes a resource control that enables the network applications to access shared resources, such as data and content used by the network applications, thus allowing the applications to interoperate and for functionality enhancements to be added.

    摘要: A communication device invokes its various device capabilities according to context information about the device. Events, which may be initiated by a user or may occur without direct user involvement, are mapped to the various functions that implement the capabilities of the device. The mapping may be updated dynamically and automatically as the context information changes and new context information received. User data and system data are also stored as the data are accumulated. When an event occurs, one or more functions that are associated with the event according to the current mapping are invoked. The user and system data may also be passed on for use with the invoked functions.
