Early April 1st headline

No doubt. What a terribly misleading article. However, the ruling is very interesting. The issue over disclosure of the source code is fascinating.

Dear people who type in all lowercase,

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.

Agreed. The processing times of the ASICs in the car and the key would have to be extremely well calibrated with very low clock drift tolerances. Crypto would all have to be out of band, with some kind of signature exchange at the end of the process to validate the message chain.

Good luck with the patent.

No, they don't. The keys passively send out signals without user interaction, probably in response to a signal sent out by the car which has a bigger battery than the key. In either case, if you have a keyless car, the car communicates with the key without user interaction.

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.

Meanwhile companies that contribute to open source can write down the entire expense of development including salaries, benefits, software, facility, and equipment.

Cut and paste.

They are using the Low Voltage Differential Pairs to transmit some information and single ended bidirectional connections for other data. Let's you use one HDMI port for multiple data sources.

The chromium open source tar ball will continue to be updated and support 32-bit x86 and ARM for at least the next 5 years.

The proprietary Chrome binaries which include features listed below will not longer be updated after March 2016:

- AAC, H.264, and MP3 Support
- Adobe Flash (PPAPI)
- Google Update

In order to prove standing, he will have to prove that he's sustained damages. He will find that hard to do. The kid might as well sue for having his financial future mortgaged to a hilt while he is at it. At least in that case, he could document how he is being royally screwed.

Imagine driving along the highway and seeing a billboard with nothing on it, except...
