Maintenance Tip: Wax The Lights

Wax
Okay, we admit it's a little detail, but in winter’s gloom and short days, every last lumen you can squeeze out of your headlamps is going to improve your safety.

Here's an easy two-minute drill: Make sure the headlamps are clean of dirt, rub car wax (any type will do) on the lamps, let it dry and buff it off. Repeat. For bonus points, do the taillights.

The slippery surface you leave behind will be less likely to build up an "icicle" coat when road slush refreezes on your car -- and will make it easier to remove it if it does.

Toyota and Microsoft working on driver gesture recognition

Raise your hand, palm up, and the radio volume in your car goes up. Toyota sees gesture recognition as one way to reduce the complexity of cars. Not for steering and braking, but to deal with the secondary controls such as infotainment, navigation, or your cellphone. So says Jim Lentz, head of Toyota in the US. The goal is to reduce driver distraction.

Toyota’s Board of Awesomeness (seriously) research team is working with Microsoft, a company that has spent years trying to reduce crashes. Their research vehicle is an electric skateboard with a Windows 8 tablet and Kinect motion sensing software (pictured below). In this case, raising or lowering the rider’s hand changes the speed. So, probably, does falling off.

This is all theoretical research right now while Toyota and Lexus soldier ahead in production cars with touchscreens, voice recognition, the Entune/Enform infotainment interface, and Remote Touch, the haptic feedback joystick-like device on some Lexuses that controls the LCD display. “Imagine a dashboard where there are no buttons to push… no screens to tap… and your eyes can remain focused on the road. That’s exactly what Toyota is working on,” Lentz said in a speech at the recent Los Angeles Auto Show.

“This could potentially work in conjunction with voice recognition which sometimes can be hindered by accents or mispronunciations. Hand gestures are pretty universal,” Lentz added. “I’ll wait for a few seconds while you insert your own punch line.”

Separately, Lentz said Toyota in Japan is prototyping the Smart Insect (pictured right), a single-passenger electric vehicle with cameras facing inside and outside the car, gesture and voice recognition, motion sensors, and behavior predictions. For instance: Walk up to the car and it recognizes the driver’s face, blinks the headlamps, and unlocks and opens the doors. Sit down and the car says “Hello” or whatever the driver desires. Think custom ringtones-plus. Gesture recognition and the Smart Insect, Lentz says, “are just a few examples of the many types of mobility automakers are creating for a better tomorrow.”

How tall can a Lego tower get?

Normal 0 false false false EN-US X-NONE X-NONE

Lego
There has been a burning debate on the social news website Reddit.

It's a trivial question you might think, but one the Open University's engineering department has - at the request of the BBC's More or Less programme - fired up its labs to try to answer.

"It's an exciting thing to do because it's an entirely new question and new questions are always interesting," says Dr Ian Johnston, an applied mathematician and lecturer in engineering.

Looking on the internet, he expected to find the answer, but was surprised to find only a lot of speculation.

Perhaps that's because not everyone who has pondered the question has ready access to a hydraulic testing machine.

The 2x2 Lego brick looks vulnerable, placed on top of a metal plate, which a hydraulic ram is pushing upwards. On top of the brick is a second plate, with a load cell on top of it, measuring the force being exerted.

Safety glasses on, the engineers begin to nervously edge towards the door.

"We're setting it up automatically, so that we can all back out of the room, so none of us is in range when the thing goes bang," Johnston explains - positioned, I notice, slightly behind me.

And the load on top of the brick gets larger and larger. We reach 3,500 newtons (N) of force - the equivalent of having 350kg (770lbs) sitting on top of the brick - more than a third of a tonne.

I'd be delighted to meet a Lego builder who could make a 3.5km tower”

Ian Johnston Open University

The force climbs on, above 4,000N. And then...

Nothing.

Well, not much. There is no big bang. The brick just kind of melts.

It looks like a small square of warm camembert.

This, Ian Johnston explains - noting that the computer also shows the load is no longer increasing - is a "material failure".

"The material is just flowing out of the way now and it's not able to take any more. We're getting a plastic failure. It means the brick keeps on deforming, without the load increasing. Metals can be plastic, and this plastic is being plastic," he says.

So - how many Lego bricks, stacked one on top of the other, would it take to destroy the bottom brick?

Ian Johnston and the team do two more tests to be sure we hadn't just happened upon the strongest Lego brick in existence. And in fact they were impressed at the consistency of Lego manufacture.

The average maximum force the bricks can stand is 4,240N. That's equivalent to a mass of 432kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000.

So, 375,000 bricks towering 3.5km (2.17 miles) high is what it would take to break a Lego brick.

"That's taller than the highest mountain in Spain. It's significantly higher than Mount Olympus [tallest mountain in Greece], and it's the typical height at which people ski in the Alps," Ian Johnston says (though many skiers also ski at lower altitudes).

"So if the Greek gods wanted to build a new temple on Mount Olympus, and Mount Olympus wasn't available, they could just - but no more - do it with Lego bricks. As long as they don't jump up and down too much."

Monday Maintenance Tip: Check your tire pressure

Tires
Here are two good reasons to get down there with the gauge and unscrew the valve caps as the weather cools:

1) Tires lose a pound of pressure for every drop of 10 degrees Fahrenheit.

2) An underinflated tire won't "bite" through snow down to the pavement as well as one at pressure. It's similar to hydroplaning on water -- and just as dangerous. You may have heard the guidance to let air out of your tires for sand or snow to get more contact surface area. That only applies only if the surface is bottomlessly soft, like a beach or foot-deep, unplowed snow -- not the mix of cleared road, ice and packed snow most of us encounter in daily driving.

Don't forget to put the valve caps back on (or, buy new ones) when you're done. Letting in moisture, which then freezes, could let the valve core leak out air.
