Abstract

A network computing device, known as a CyberHub, based on low-cost hardware and Java programming provides an architecture for extensible and inexpensive network connectivity and can be thought of as a combination of router and server in a box. The CyberHub provides all necessary functions with a small footprint and lightweight components, so that it can perform as an embedded device or thin server. The CyberHub can be employed in many different applications, ranging from an “instant office” to embedded network connectivity for remote devices.

Claims

1. An extensible thin server for computer networks, comprising:

(a) a computing device coupled both to a network; and

(b) a software platform, executed by the computing device, the software platform being comprised of a plurality of components for providing basic functionality on which one or more applications are based, wherein the components are selected from a group comprising;

one or more Services for grouping application-specific functions, one or more Class Loaders for loading the application-specific functions associated with the Services, one or more Handlers for processing requests for the Services received from the network, a Registry for associating different ones of the Handlers with specific ones of the requests received from the network, and an Access Control List (ACL) Manager for controlling access to the resources of the computing device and the software platform.

2. The extensible thin server of claim 1 above, further comprising means for packaging a Service in a single file.

3. The extensible thin server of claim 1 above, further comprising means for adding Services by adding files to the extensible thin server.

4. The extensible thin server of claim 3 above, wherein the means for adding further comprising means for adding Services by downloading the files to the extensible thin server.

5. The extensible thin server of claim 1 above, further comprising means for deleting Services by deleting files from the extensible thin server.

6. The extensible thin server of claim 1 above, wherein the Registry comprises a list of Uniform Resource Locators (URLs) that the Handler processes.

7. The extensible thin server of claim 1 above, further comprising a managed device coupled to the computing device.

8. The extensible thin server of claim 7 above, wherein one or more of the Services provides programmable control for the managed device.

9. The extensible thin server of claim 7 above, wherein one or more of the Services process data collected from the managed device.

10. The extensible thin server of claim 9 above, wherein one or more of the Services formats the collected data for display.

11. The extensible thin server of claim 9 above, wherein one or more of the Services transfers the collected data to a remote device via the network.

12. The extensible thin server of claim 9 above, wherein one or more of the Services logs the collected data to a storage device.

13. The extensible thin server of claim 12 above, wherein the storage device is local to the computing device.

14. The extensible thin server of claim 12 above, wherein the storage device is remote from the computing device.

15. The extensible thin server of claim 1 above, wherein one or more of the Services provides rule-based event handling.

16. The extensible thin server of claim 7 above, wherein the managed device is a biomedical device.

17. The system of claim 16 above, wherein one or more of the Services collect data from the biomedical device.

18. The system of claim 17 above, wherein one or more of the Services applies a filter to the collected data from the biomedical device.

19. The system of claim 17 above, wherein the data is collected in response to received commands.

20. The system of claim 17 above, wherein one or more of the Services creates data visualization displays for the collected data.

21. The system of claim 17 above, wherein the data visualization displays resemble a control panel of the biomedical device.

22. The system of claim 17 above, wherein one or more of the Services displays data from a plurality of the biomedical devices substantially simultaneously.

23. The system of claim 17 above, wherein one or more of the Services logs the data collected from the biomedical device.

24. The system of claim 17 above, wherein one or more of the Services perform rules-based event handling.

25. A method for operating an extensible thin server in a computer network, comprising the steps of:

(a) loading a software platform on a computing device coupled to a network, the software platform being comprised of a plurality of components for providing basic functionality on which one or more applications are based, wherein the components are selected from a group comprising;

one or more Services for grouping application-specific functions, one or more Class Loaders for loading the application-specific functions associated with the Services, one or more Handlers for processing requests for the Services received from the network, a Registry for associating different ones of the Handlers with specific ones of the requests received from the network, and an Access Control List (ACL) Manager for controlling access to the resources of the computing device and the software platform; and

(b) executing the software platform on the computing device, including selectively executing the application Services, the Class Loaders, the Handlers, the Registry, and the ACL Manager.

26. An article of manufacture comprising a computing device coupled to a network and embodying logic executable by the computing device to perform method steps for operating as an extensible thin server in a computer network, the method comprising the steps of:

(a) loading a software platform on computing device, the software platform being comprised of a plurality of components for providing basic functionality on which one or more applications are based, wherein the components are selected from a group comprising;

one or more Services for grouping application-specific functions, one or more Class Loaders for loading the application-specific functions associated the Services, one or more Handlers for processing requests for the Services received from the network, a Registry for associating different ones of the Handlers with specific ones of the requests received from the network, and an Access Control List (ACL) Manager for controlling access to the resources of the computing device and the software platform; and

(b) executing the software platform on the computing device, including selectively executing the application Services, the Class Loaders, the Handlers, the Registry, and the ACL Manager.
