1. An electromechanical damper for a vehicle for damping between two components mechanical oscillations by which a drive torque is transmittable to an electric generator for generating a damping force, said damper comprising:
a first gearbox constructed in the form of a planetary gear train having a sun wheel connected to one end face of a rotor of the generator, a ring gear, and planet wheels in mesh with the sun wheel and the ring gear;
a second gearbox constructed in the form of a planetary gear train having a sun wheel connected to another end face of the rotor, a ring gear, and planet wheels in mesh with the sun wheel and the ring gear; and
a stator housing forming a gear element which is integrated in the first and second gearboxes,
wherein the sun wheel, ring gear and planet wheels of the first and second gearboxes are each provided with helical teeth in axial direction, with the helical teeth of the sun wheel of one of the first and second gearboxes and the sun wheel of the other one of the first and second gearboxes being directed in opposition to one another.
2. The electromechanical damper of claim 1, wherein the helical teeth are oriented at an angle of about 45\xb0 in relation to the axial direction.
3. The electromechanical damper of claim 1, wherein the first and second gearboxes are arranged on both sides of the generator.
4. The electromechanical damper of claim 1, wherein the ring gear of the first gearbox and the ring gear of the second gearbox form jointly with the stator housing a single-piece structure, with the planet wheels forming input elements of the first and second gearboxes via which input elements drive torques are introduced into the first and second gearboxes.
5. The electromechanical damper of claim 1, wherein the stator housing is connected in fixed rotative engagement with a coupler, which is linked to the damper, for introducing oscillations into the damper.
6. The electromechanical damper of claim 1, wherein each of the first and second gearboxes has a planet carrier for supporting the planet wheels, and further comprising a connection element placed between the first and second gearboxes and connected to a vehicle body, said planet carriers of first and second gearboxes being connected in fixed rotative engagement with the connection element.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A context-aware proxy server system, comprising
a proxy engine that processes a request from a client system coupled to the proxy server system to retrieve a web page from a remote web server and pass the web page to the client system;
a context store that stores context information of the client system;
a transformation module coupled to the proxy engine and the context store to add the context information into the web page before the web page is sent to the client system such that services specified in the context information can be readily invoked by the client system via the modified web page.
2. The proxy server system of claim 1, wherein the context information of the client system specifies web-enabled services available to the client system.
3. The proxy server system of claim 2, wherein the context information specifies each of the web-enabled services in the form of a command-like URL (Universal Resource Locator).
4. The proxy server system of claim 2, wherein the transformation module adds the context information into the web page by creating and embedding a context-menu directly in the web page adjacent to a content item, wherein the context-menu includes a list of URL commands specifying a plurality of web-enabled services.
5. The proxy server system of claim 4, wherein each of the URL commands is a location-aware, and URL-dependent command.
6. The proxy server system of claim 1, wherein the context information of the client system specifies web-enabled services offered by physical devices adjacent to the client system.
7. The proxy server system of claim 1, further comprising a plurality of client systems coupled to the proxy server system, wherein the context store stores the context information of each personalized environment of each of the client systems and the transformation module also transforms the web pages sent to these client systems by adding their corresponding context information into the web pages.
8. The proxy server system of claim 7, wherein each of the client systems can be stationary or mobile.
9. A method of including context information of a client system into a web page sent to the client system, comprising
storing the context information in a proxy server coupled to the client system;
processing a request from the client system to retrieve the web page from a remote web server;
adding the context information into the web page before the modified web page is sent to the client system such that services specified in the context information and available to the client system can be readily invoked via the modified web page.
10. The method of claim 9, further comprising the step of sending the modified web page to the client system.
11. The method of claim 9, wherein the context information specifies web-enabled services available to the client system.
12. The method of claim 11, wherein the context information specifies each of the web-enabled services in the form of a command-like URL (Universal Resource Locator).
13. The method of claim 11, wherein the step of adding the context information further comprising
creating a context-menu that includes a list of URL commands specifying a plurality of web-enabled services;
embedding the context-menu directly in the web page adjacent to a content item.
14. The method of claim 13, wherein each of the URL commands is a location-aware, and URL-dependent command.
