摘要:
Methods, systems and computer program products are provided for automatically generating client/server applications from an application written to execute on a single processing system. The application has program classes and programmed methods associated with the objects. Each program class in the application is identified and the relationships between programmed methods in the classes is determined. The relationships between the programmed methods in the identified classes are then weighted based on the activity of the relationship. Similarly, each identified class in the application is also weighted based on the computing resources required by the identified class. The identified classes are then partitioned into client classes and server classes based on the weighted relationships between the programmed methods in the classes, the weight associated with each class and a computing topology associated with a target client processing system. The resulting client and server partition may then be used for code generation and distribution based on the capabilities of a requesting computer system.

The automatic object distribution of the present invention allows object oriented programs to be run as distributed programs without any explicit networking code, and without using an interface definition language (IDL). The present invention allows programmers to experiment with different distributions without complicating the programming task. It accomplishes this by generating two proxies that allow method calls written for local invocation to be invoked over a network. These dynamically-generated proxies allow calls to flow across a network as if they were local.

An implantable nanosensor includes a stent to be implanted inside a fluid conduit. The stent has a well in a surface of the stent. The implantable nanosensor further includes a nanoscale-patterned sensing substrate disposed in the well. The nanoscale-patterned sensing substrate is to produce an optical scattering response signal indicative of a presence of an analyte in a fluid carried by the fluid conduit when interrogated by an optical stimulus signal.
