Re: Re : Tiny Sensor Monitors Batteries on Start-Stop Cars

The current average switches change phases at rates of millions per second. That is not so bad and it's actually what we just started getting used to. From this, the new optical switches can change phases trillion times per second. I put up this comparison to give a better picture of how fast a processor fitted with an IC that has this kind of switches would be. Literally this would be more than 500times faster than the best processors in the market today, even after considering other factors that will limit its efficiency.

Start-stop vehicles, in as much as they are supposed to help drivers save energy, can be a real nuisance. I don't own one yet and I don't plan on doing so anytime soon because I generally believe they are unpredictable. Their starters are either working or they are not so if you stop your car and it fails to restart because the battery power is low, you have no option but to recharge the battery or look for an alternative power source before you can drive it again. My old school, manual transmission Toyota, on the other hand, will cooperate once I jump-start the battery.

The sensors are a great innovation indeed but I have issues regarding their preferred areas of application. For starters, I don’t see them having much use at traffic stops. They are practically redundant in that there is very little they can help you do in such situations. Let me illustrate; say you are approaching a traffic light and it turns red. At the same time, your sensors tell you that your battery power is low and you will not be able to restart the car once you stop at the red light. Whatever the sensor says will not really matter because either way you will still have to stop at the red light.

Start/Stop Future

Nice niche product, I'd design it in rather than spinning my own battery monitor. The real question is if start/stop vehicles have a future.  Consumers are used to cushy climate control systems, and I see them objecting loudly when stopped at a long light on a warm day in a start/stop vehicle.

Important evolutionary technology

Technology like this may seem like a small thing but it's evolutionary and key technology to help enable the next generation of efficient automobiles. This will be an important enabling technology as these new start-stop autos continue to enter the market and the roads.

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
At Medical Design & Manufacturing Midwest, Joe Wascow told Design News how Optimal Design prototyped a machine that captures the wing-beat of a duck.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
