PITTSBURG, Sept 15, 2016:  Beating all competition in the silicon valley Uber did a test ride of its driverless cars in Pittsburg.Competitors such as Volvo and Google have invested hundreds of millions of dollars and logged millions of miles test driving autonomous vehicles, but Uber is the first company in the U.S. to make self-driving cars available to the general public.

Starting Wednesday morning, a fleet of self-driving Ford Fusions will pick up Uber riders who opted to participate in a test program. While the vehicles are loaded with features that allow them to navigate on their own, an Uber engineer will sit in the driver’s seat and seize control if things go awry.

That pilot really pushes the ball forward for us,” said Raffi Krikorian, Director of Uber Advanced Technologies Center (ATC) in Pittsburgh, the company’s main facility for testing self-driving vehicles. “We think it can help with congestion, we think it can make transportation cheaper and more accessible for the vast majority of people.”

A reporter from The Associated Press tried out the service Monday. The ride through downtown Pittsburgh and over some bridges went smoothly, with the car waiting for oncoming traffic before making a turn and at one point stopping for a vehicle that was backing into a parking space. Parking, however, was a task the human driver had to perform.

This real-time map is constantly being matched against a map that’s been pre-loaded into the car’s brain. Uber collects the new, real-time data from its cars twice a day, and it pushes updated maps to its cars once a week.

What allowed Uber to get to the front of the pack was not auto engineering but rather its ability to accumulate and crunch massive amounts of data on road and driving conditions collected from the billions of miles driven by Uber drivers.”We have one of the strongest self-driving engineering groups in the world, as well as the experience that comes from running a ride-sharing and delivery network in hundreds of cities,” said Uber founder and chief executive Travis Kalanick.

But even if Uber manages to get the driverless cars on the road and running, there’s still a matter of legislation issues as even if a car is fully functional and equipped it still requires a driver with a legitimate license behind the wheel according to the current laws which of course might undermine the whole point of making mechanised cars.

But bigger changes in laws have been done and nobody can undermine the huge technological advancement that is represented by these driverless cars.

    Technology is making its way to the top.
    Amazing news but will it be successful? will people be fine with a car that is fully automatic and does not have a driver?

Tiny Pacemakers Could Be Game Changers for Heart Patients

A pacemaker is a medical device which uses electrical impulses, delivered by electrodes contracting the heart muscles, to regulate the beating of the heart

Tiny, new pacemakers are making headway around the world. One type, the Micra, is keeping 15,000 people’s hearts beating in 40 countries, according to manufacturer Medtronic. One of those people is Mary Lou Trejo, a senior citizen who lives in Ohio.

A healthy heart has its own pacemaker that establishes its rhythm, but people like Trejo need the help of an artificial device.

Trejo comes from a family with a history of heart disease. Her heart skipped beats, and she could feel it going out of rhythm. Trejo wanted to do something to advance heart health, so in 2014, she volunteered to participate in a clinical trial for the Micra pacemaker. The device is 24 millimetres long implanted, one-tenth the size of traditional pacemakers.

Traditional pacemakers

Most pacemakers rely on batteries placed under the skin, usually just below the collarbone. Sometimes patients get infections after the surgery or have difficulty healing from the incision.

Traditional pacemakers use leads with electrodes on one end that are threaded through blood vessels to connect to the heart. There can be problems with the leads as well.

Dr Ralph Augostini at Ohio State’s Wexner Medical Center says a tiny pacemaker like the Micra avoids all of these problems.

“The electrodes are part of the can, and therefore it eliminates the lead,” he said. There’s no incision in the chest to become infected and no chance of complications with the leads.

Small and self-contained

Augostini implanted Trejo’s pacemaker in 2014. He threaded the entire device through an artery in her leg up to her heart. The pacemaker has small, flexible tines that anchor it into the folds of the heart muscle. Once it’s in place, the doctor gives it a tug to make sure the pacemaker is stable before removing the catheter used to place it in the heart.

The Wexner Medical Center was one of the sites that participated in the Micra clinical trial. Since the Micra received FDA approval in 2016, Medtronic has been training more physicians on the procedure. A company spokesman told VOA that this device is becoming available at other centres across the U.S. and countries throughout the world.

Dr John Hummell, a cardiologist at the Wexner Medical Center, has studied the effectiveness of this new generation of pacemakers.

“We don’t leave any wires behind and the pacemaker, the battery, the wire is all just a tiny little piece of metal sitting down in the heart,” he said. Medtronic said the results of the clinical trial showed a success rate of 99.6 percent.

Dr Richard Weachter, with the University of Missouri Health Care, says the leadless pacemakers’ complication rates are about half the rate of traditional pacemakers.

The battery lasts for 14 years and after that, Weachter said, doctors, can implant another one in the same chamber of the heart. They can repeat the procedure a third time if needed.

The pacemaker activates only when necessary to keep the heart beating normally. Studies show that the Micra and other leadless pacemakers are safe and effective.

These tiny pacemakers are not right for all patients, but as the technology develops, more people will be able to benefit from the procedure. Four years after her implant, Trejo’s doctors say she is doing fine. (VOA)
