Tiny IoT Temperature Sensor Powered Wirelessly with Radio Waves

As reported by GizMag: One of the problems for the smart buildings of tomorrow is that they may depend on some very un-smart wires to power them. To cut the cord, Eindhoven University of Technology (TU/e) researcher Hao Gao, as part of his PhD thesis, has developed a tiny transmitting temperature sensor that is powered by radio waves, eliminating the need for wires or batteries. Instead, it picks up radio waves from a special router, converts them into electricity, and uses it to transmit readings.

Like many other forecasters, TU/e sees a future where smart buildings are filled with sensors and other devices that gather information and carry out tasks to automate the business of living while making it more sustainable. But as sensors become smaller and are incorporated into more things around the house, the problem of powering them without stringing tiny wires everywhere or spending half the time swapping out batteries remains.

Part of the PREMISS project, Gao's sensor is very much in the lightweight category at 2 sq mm and weighing in at 1.6 mg. Its operating principle is similar to that of the Thing, which is infamous in espionage circles as the Soviet bug that listened in at the US embassy in Moscow for about six years.

In 1946, a carved replica of the Great Seal of the United States was presented by the Soviets to the embassy as a goodwill gift that seemed the picture of innocence. What that Americans didn't know is that under the woodwork was the Thing, which was a listening device with a monopole antenna. Instead of running off batteries or mains current, the Thing was energized by a radio beam directed at it by the KGB and transmitted back when they wanted to eavesdrop on the ambassador. This meant that it could operate indefinitely and was only discovered in 1952 by accident when a British radio operator tuned in on its transmissions.

Various research teams have also been examining the potential of scavenging ambient radio waves to power all manner of devices, such as biomedical implants and smartphones. 

Based on 65-nm CMOS technology, the new thermometer system uses a special router that targets the sensor, but unlike the Thing the reason is to save power rather than escape detection. At the same time, the sensor itself is designed to use very little electricity. When the sensor is exposed to radio waves, it absorbs the energy until it stores enough to transmit a signal back to the router. The temperature of the sensor alters the frequency of the signal, which the router can decode.

According to TU/e, the tiny size and independent nature of the sensor means that it can be placed in all sorts of unorthodox locations, such as in plaster or concrete. It can even be mixed in with latex and applied directly to walls like paint.

The current version of the sensor has an operating range of only 2.5 cm (1 in), but it's hoped that this will be extended to a meter (3 ft) in a year and ultimately to 5 m (16 ft). With a mass production cost projected at about 20 cents, TU/e sees a wide range of applications for the wireless sensors, including payment systems, wireless ID, smart buildings, and industrial applications.

Nanomaterial for GPS Clocks Most Expensive in the World at $150 Million per Gram

As reported by the Independent: Oxford University scientists are creating the world's most expensive material - endohedral fullerenes, spherical carbon molecules containing nitrogen atoms, which sell for £100 million ($150 million) a gram.

The tiny structures are being manufactured by Designer Carbon Materials, a company which was born out of the university last year.

The incredibly valuable material is being used in atomic clocks, to make the timekeeping deviceseven more accurate than ever before.

When integrated into a GPS device, the tiny clocks could detect the device's position to an accuracy of one millimeter, compared to the current standard of around one to five meters.

That accuracy would be practically unnoticeable if you were navigating a city with Google Maps, but it's vital in driverless car technology, where the difference between meters and millimeters is hugely important to avoid collisions.

Speaking to The Telegraph, Dr Kyriakos Porfyrakis, founder of the company and nano-materials expert, said: "Imagine a miniaturized atomic clock that you could carry around in your smartphone."

"This is the next revolution for mobile."

Most current atomic clocks are large, in some cases, cabinet-sized devices. Using the endeohedral fullerene technology, they could be shrunk to the size of a microchip.

Because of the enormous price, the material changes hands in tiny quantities.

The company recently made their first sale of only 200 micro-grams - about one-fifteenth the weight of a snowflake, or one-third the weight of a single human hair - for £22,000 ($33,000).

Success! Cygnus Spaceship Launch Restarts Orbital ATK Cargo Missions for NASA

As reported by Space.com: With a brilliant afternoon launch, the private spaceflight company Orbital ATK returned its Cygnus cargo ship to flight after a year on hiatus Sunday (Dec. 6), launching vital supplies and NASA gear to the International Space Station.

The unmanned Cygnus spacecraft blasted off from a pad at Florida's Cape Canaveral Air Force Station at 4:44 p.m. EST (2144 GMT) Sunday after a three-day delay caused by bad weather. The liftoff marks the first resupply mission for NASA by Orbital ATK since the loss of its last Cygnus vehicle and Antares rocket in October 2014. The vehicle is expected to deliver nearly 4 tons of supplies, including a life sciences facility, microsatellite launcher, Microsoft HoloLens sets and other tools, when it arrives at the space station on Thursday (Dec. 10).

Orbital ATK was able to mount a second supply mission so quickly after last year's rocket failure by collaborating with the U.S. launch provider United Launch Alliance (ULA), which provided the Atlas V rocket that lofted Cygnus into space Sunday evening. The mission is especially important because there have been two other delivery failures in the past year, one in June by rival U.S. company SpaceX and another by Russia's Federal Space Agency in April.

Astronauts on the space station were able to watch the launch from their vantage point in orbit, capturing a stunning view of the liftoff. "Caught something good on the horizon. #Cygnus at #sunset on its way to @space_station! #YearInSpace," NASA astronaut Scott Kelly, who commands the station's six-man crew and is flying a one-year mission to the outpost, wrote on Twitter after launch.

"Within a few days [of the failed launch last year], we had a plan," Frank Culbertson, Space Systems Group president at Orbital ATK and retired NASA astronaut, said in a press briefing Wednesday (Dec. 2). "With the help of our friends at ULA, who stepped forward and offered us a ride in a very short period of time, we've reached this point," which is, he added, less than 12 months from the first discussion to launch. "That's quite an accomplishment for the commercial space industry, in my opinion — I think it says a lot about what we can do to support NASA and all of exploration in space."

Cygnus separated from its Atlas V booster about 21 minutes after launching into orbit. It is due to rendezvous at the International Space Station on Thursday (Dec. 10). NASA astronaut Kjell Lindgren will capture the Cygnus using the station's Canadarm2 robotic arm and attach the cargo ship to an Earth-facing port on the outpost's Unity module. That connection will be the first berthing to the port in many years, NASA officials said. NASA astronaut Scott Kelly, who commands the station and is in the midst of a one-year mission in space, is Lindgren's backup.

Orbital ATK's Cygnus spacecraft are autonomous vehicles designed to haul tons of freight to the space station, then burn up in Earth's atmosphere with trash and unneeded items aboard at mission's end. Orbital ATK names its Cygnus vehicles after astronauts, with the one launched Sundaychristened the S.S. Deke Slayton II in honor of the former NASA astronaut, one of the agency's original "Mercury Seven" spaceflyers.
Over the course of the successful first two flights in Orbital ATK's $1.9 billion, eight-flight contract with NASA, the company's Cygnus vehicles have delivered more than 7,940 lbs. (3,600 kilograms) to the space station and re-entered the atmosphere with 6,830 lbs. (3,100 kg) of trash. This time, an "enhanced Cygnus" craft is carrying more than 7,700 pounds (3,500 kg) of supplies up with it — it was able to carry even more than originally planned, due to the additional capacity of the Atlas V, Orbital ATK officials told Space.com.

The spacecraft has 25 percent more storage space than the old Cygnus and lighter solar arrays that unfold into two circular, outstretched wings to generate power. After about a month, the craft will return to Earth, burning up in the atmosphere over the Indian Ocean.

The next Cygnus launch, in March, will also ride to space on an Atlas V, but after that, Orbital ATK will debut an updated version of the company's Antares rocket.

Big science aboard

The Cygnus that launched Sunday is carrying several experiments on board, including a life sciences research module the size of a locker, a research project to evaluate flame-resistant and flame-retardant textiles in microgravity, an exploration of gas and liquid movement, and two different systems for networking small satellites or modular pieces into a larger whole. The vehicle is also carrying Microsoft HoloLens headsets that will let experts on Earth help station crewmembers with complicated tasks (originally set to be sent on the failed SpaceX Dragon cargo ship launch in June) and a safety jetpack for spacewalks.

Plus, Cygnus will bring several student experiments on board, five of which first took flight on earlier, failed launches over the past year, along with replacement parts for the space station and added consumables for the crew. (This includes a student-built satellite bearing a medallion that was blessed by the Pope.)

"I just can't emphasize enough how it's important to us, on board ISS, to have a regular cadence of resupply flights," Kirk Shireman, the program manager for ISS, said during the briefing. "We're so much looking forward to having Cygnus back on, and of starting a new era on ISS [going] back to regular resupply flights — that way we can utilize ISS like it was intended." Instead of focusing on catching up, NASA will be able to send up more new experiments and components for the crew.

Still, this flight will bring some goodies of its own when it docks on Thursday: "I'm guessing that Santa's sleigh is somewhere inside the Cygnus," Culbertson added. "And they're probably excited about their stockings coming up, too."

Porsche Is Charging Ahead With Mission E 'Tesla Killer' Electric Car

As reported by Forbes: Even Porsche is gunning for Tesla Motors these days. After floating the Mission E pure electric concept in September, Porsche is going ahead with production of the vehicle.

“The first 100% electrically powered Porsche is on its way. It will be launched at the end of the decade,” Porsche said Friday in a statement. Some highlights from the announcement:

Unveiled at the Frankfurt Motor Show, the four-door car with four individual seats has a system power output of over 440 kW (600 PS). The vehicle will thus achieve both acceleration of 0 to 100 km/h in under 3.5 seconds and a range of more than 500 kilometres. 

With the Mission E project, Porsche is continuing to back sustainable growth. In Stuttgart-Zuffenhausen alone more than 1,000 new jobs are being created. The company will be investing around 700 million euros in its main site there. Over the next few years, a new paint shop and a new assembly plant will be built. The existing engine factory is also being expanded for the production of electric motors. In addition, the existing body shop is being enlarged. On top of that come other areas in which the company will be investing in this context, such as in the Weissach development centre.

Other goodies include: an 800-volt charger that juices up the battery to 80 percent of the range in about 15 minutes. And the vehicle can optionally be recharged wirelessly by induction via a coil set into the garage floor, Porsche said.

The giant asterisk to all of the above is of course that Porsche is doing this by the end of the decade. The Tesla Model S is here and now.

Pro Drivers Go Headset-to-Headset in VR Race on Two Separate Tracks (Video)

As reported by The Wall Street Journal: In a race that fuses video-game technology and real world driving skill, two professional drivers, on two separate but identical tracks, have raced against each other while wearing virtual reality headsets attached to their crash helmets.

The race, which took place on November 10 at Los Angeles’ Santa Anita track, saw the drivers looking not at the actual road in front of them, but at a virtual reality representation of the track, infused with smoke, fire, waterfalls, and boulders.

The drivers, one of whom drove a stunt car in the latest James Bond film ‘Spectre,’ hurtled around the circuit in two identical 2015 V8 Ford Mustangs, trusting that what they were seeing on their Oculus Rift DK2 VR headsets was a true, real-time representation of how their cars were performing on the actual track.

“The main risk is, if I go blind and I can’t see where I’m going at 70 mph, I could thunder into a tree which would not feel very nice,” said U.K.-based stunt driver Ben Collins.

“The beautiful thing about virtual reality is you can press reset without killing yourself.”

To get the real-virtual mix right, technologists working for car oil company Castrol, which produced the event, mixed virtual reality with self-driving car technology.

One of the main challenges: tracking the cars’ exact positions as they sped around the track without the need for re-calibration. This was necessary so that an exact match could be achieved between what was happening on the physical track and its representation on the VR screens.

To track the cars, a system frequently used to navigate robots around a space was used, integrating a combination of physical, optical, and laser sensors gauged the position of the cars at high speeds during the race.

To get the two cars to communicate their locations without any significant transmission latency within the headset–which could cause the drivers to crash as they would not be accurately judging their vehicles’ orientation and locations– the technology team had to make sure that a fast Internet connection in the area of the race tracks would send all the data from the cars and the surrounding cameras and sensors to a powerful, on-site server.

The race comes as VR hardware and software is expected to hit the mainstream market in 2016, with companies like Facebook Inc. marketing the Oculus Rift VR headset and Sony Corp. promoting its PlayStation VR.

Google's New Computer 'Vision' Tech is Very Cool and Somewhat Terrifying

As reported by Business Insider: Google on Tuesday announced a new tool on Wednesday for app developers that's absolutely amazing and also a little disturbing: it lets apps, robots and drones "see."

The tech is called the Google Cloud Vision API and it allows any app developer to tap into Google's smart "machine learning" service that can identify objects, including faces and emotions.

Cloud Vision solves a hard computer problem of "seeing." For instance, your computer can scan and reproduce an image of a mountain or an image of a baby, but to the computer, they look the same: a bunch of pixels. Your computer can't sift through your photos and find baby photos for you, unless you've tagged them "baby."

Google Photos, on the other hand, can find the baby photos.

And now Google is making that technology available to programmers to add to their apps. 

Cloud Vision can even detect various emotions on a face such as a happy smile or an angry frown, Google says.

To demonstrate the power of Cloud Vision, Google built a cute little robot with Cloud Vision, via a DYI robot kit known asGoPiGo. 

At 1:14 in the video below, the robot demonstrates how it can follow faces and detect emotions. At 2:08, the robot demonstrates how it can detect and identify other objects like glasses, a banana, money.

As for the terrifying part ...

While the demo robot is 'adorbs', it doesn't take much imagination to see less cuddly uses for computer vision.

For instance, at least one drone maker has been testing Google Vision out: Aerosense, owned by Sony Mobile Communications. 

"We have drones that take thousands of photos per flight. We find that Google Cloud Vision API as the best way to turn those huge number of photos, automatically produced, into meaningful insights,"Aerosense General Manager Tomoaki Kobayakawa says on Google's blog.

And given Amazon's recent news that its drone delivery project is progressing, we can't help thinking of that Audi commercial featuring people-seeking delivery drones run-amok.

SpaceX's Launch Escape System Looks Totally Badass

As reported by Gizmodo: In two years, SpaceX will begin ferrying astronauts into orbit. But before it can do so, the commercial spaceflight company must prove to NASA that its ride will be safe. A big part of that guarantee comes from the fire-breathing propulsion system pictured above.

Arranged in four pairs around the outside of a Crew Dragon spacecraft, SpaceX’s SuperDraco engines are a first-of-its-kind launch escape system. In the event of a booster failure on the way to orbit, the SuperDracos will all fire at once, collectively producing 120,000 pounds of thrust. That’s enough to accelerate a Crew Dragon from zero to 100 mph in a rip-roaring 1.2 seconds, boosting the astronauts well out of harm’s way. Eventually, SpaceX plans to use the system in place of a parachute during landings.

Each of the engines in the module pictured above has been test fired over 300 times. Just watching them ignite in the lab is getting me stoked for the future of commercial spaceflight.
