Results 3954 hits ( I found that many of patents/applications are repeated in the the search result with different relevance scores. Greg said that he was aware of that and would fix this problem soon. After this problem is fixed, the actual hits will be a lot less). I checked the first 400 hits and obtained the following patents/applications:

 

Comments Apart from the patents/applications I have obtained before, the following patents/applications in the list are relevant or could be included in this ladscape:
