As I understand tje JAVA lic, and perhaps I'm mistaken, but it seems pretty clear that Sun lic the programming language for free but retained the lic and copyright on the implementation of the language itself.

I'm not sure how this would be relevant. Last I checked neither android nor the android SDK implement a java compiler at all. They rely on the JDK for compiling. They do static binary translation from JVM byte code to Dalvik byte code.

There are some fairly large differences between Dalvik (the vm in android) and the JVM from sun/oracle/whoever. Namely the Dalvik instruction set is register based whereas java is stack based. You can easily have any engineer look at the code for the Dalvik vm itself and see there is quite a difference. Then the libraries that aren't android specific are based on the Apache harmony project so affidavits from Google engineers would be quite useless there. Now the question to me wouldn't be in Android itself but is the Android SDK truly clean room. There's a static re-compiler to recompile JVM bytecode to Dalvik bytecode. My guess is the SDK is clean room itself but Schmidt being honest about android being clean room isn't so unlikely but it is quite possible this is doublespeak and the SDK itself (hey it's not "Android") could very well be based on Sun IP. The relevant stuff I've seen in this court case hasn't related to so much lifted code as it was patents which is quite difficult to avoid infringing just by not seeing code.

Changing the Texture of Plastics On Demand 48

Or maybe gloves with "fingerprints" that can be changed in the blink of an eye. They are just a couple of the many potential applications envisioned by researchers at Duke University for a process they have developed that allows the texture of plastics to be changed at will. By applying specific voltages, the researchers have been able to dynamically switch polymer surfaces among various patterns ranging from dots, segments, lines to circles."
