Comment This isn't a victory for Behring-Breivik. (Score 3, Insightful) 491

Someone once pointed out that hoping a rapist gets raped in prison isn't a victory for his victim(s), because it somehow gives him what he had coming to him, but it's actually a victory for rape and violence. I wish I could remember who said that, because they are right. The score doesn't go Rapist: 1 World: 1. It goes Rape: 2.

What this man did is unspeakable, and he absolutely deserves to spend the rest of his life in prison. If he needs to be kept away from other prisoners as a safety issue, there are ways to do that without keeping him in solitary confinement, which has been shown conclusively to be profoundly cruel and harmful.

Putting him in solitary confinement, as a punitive measure, is not a victory for the good people in the world. It's a victory for inhumane treatment of human beings. This ruling is, in my opinion, very good and very strong for human rights, *precisely* because it was brought by such a despicable and horrible person. It affirms that all of us have basic human rights, even the absolute worst of us on this planet.

This problem has been solved in TOF laser range finders, like the hand held ones used on golf courses. An expander chip takes the incoming analog signal and stretches it out a million times with considerable precision. The signal can then be analyzed by standard low cost and low power processors.

The challenge here is that instead of a reflecting laser, you have the call/process/response in the equation. That process time will be orders of magnitude larger than the signal traversal. So, you'd have to have very accurate and standard processing times.

Comment timestamps (Score 2) 228

Solution:

(Assuming the key/car are using private/public key pairs)

You'd have to put a reasonably accurate clock in the key, and then have it encrypt and send timestamps to the vehicle using a sequence of rapidly fired request messages followed by response messages.

The car could then decrypt the messages and compare the timestamps from the sequence of messages measuring the distance between the key and the car. The clock in the key would have to have similar accuracy to a laser ranger finder.

The actual protocol would be a bit more complicated in the details, but the basics outlined above are what is needed.
