Impressive all the laws of nature and tech is use to monitor the Marginal Ice Zone in the Arctic
“Among the sensors the scientists placed on the ice in March were a set of eight acoustic navigation beacons. These have base-stations at the surface, which fix their locations using GPS. They then rebroadcast that information from loudspeakers hanging 100 metres down below the ice, in the transmission layer. If a Seaglider can detect two or more beacons while it is travelling through this layer, it can swiftly compute its own position.
This may not always work, because the Seagliders might stray too far from the beacons. In that case, the researchers have a pair of robotic guide dogs to assist. These are called Wave Gliders (pictured at the top of the story). One part of each Wave Glider stays on the surface, generating electricity from solar panels during the Arctic’s 24-hour summer daylight. The other part is an array of hydrofoils suspended four metres underwater. The difference in motion between the waves above and the calm below causes water to move over the hydrofoils and propel the Wave Glider forward up to twice as fast as a Seaglider. Although Wave Gliders broadcast far above the sound layer, and thus have shorter ranges than fixed beacons, they can be programmed to shadow the Seagliders, and keep them within earshot.”
Cargill, of suburban Minneapolis, represents a formidable new competitor. Its $134.9 billion in fiscal 2014 sales ranked it as the largest U.S. agricultural firm and the country's largest privately held company. The 149-year-old company has long advised farmers on farming strategies and the best time to sell grain. In 1996, Cargill began sampling soil and experimenting with applying different amounts of fertilizer to various fields, depending on how many nutrients the ground already held, Mr. Becraft said.
NextField DataRx represents a more information-intensive version of Cargill's advisory service, incorporating historical weather data, satellite imagery and farmers' own information.
Metromile’s pitch is straightforward: Your insurance premium should be based on exactly how much you drive. The more miles you put on your car, the more you pay, because the odds are higher you’ll have a claim. Drive less, pay less.
Insurers have long asked policyholders to report mileage, but that information typically influences the bill only when drivers renew for another term. Metromile’s new customers get the Metronome, a mileage-tracking device that plugs into a car’s data port. The company uses the information to customize its rates.
If this narrative sounds familiar, that’s because it is: companies have been promising the dawn of the smart home–a futuristic dwelling full of gadgets working seamlessly to satisfy your every whim–since the ’50s. Yet early efforts failed to deliver because of clunky tech and consumer wariness.
SmartThings, which launched in 2012, has arrived amid a legitimate sea change in home automation. In the past few years, the rise of cloud computing has made it easier than ever to build gadgets that connect to the so-called Internet of Things, meaning they can be monitored and controlled from afar, usually with their own smartphone app. There’s also been an uptick in the production of sensors and devices that enable you to smartify objects that are dumb. (Think plugging a desk lamp into an adapter controlled by your phone, or rigging a door with a motion detector that pings you about intruders.) By 2018, the research firm IHS Technology predicts, people will have installed 45 million smart-home services. “We’re really starting to see major volume here,” says Lisa Arrowsmith, an IHS associate director. “It’s an exciting time.”
“The figures are striking. The Defense Department's Prisoner of War and Missing Personnel Office lists the number of troops unaccounted for from past conflicts: World War II has 73,547; Korea 7,883; the Cold War 126 and Vietnam 1,642. In comparison, Iraq and other conflicts (which also include Afghanistan, Desert Storm and Libya) have a total of six. Six unaccounted for in more than three wars; clearly something changed.”
“Innovative technology has enhanced this advantage by greatly increasing the ability of American troops to project force and rescue isolated troops. GPS technology allows American ground troops to accurately determine their location and call for precision-guided munitions that provide quick, accurate and direct combat support.Drones can linger and search over the battlefield, streaming superb battlefield intelligence. Satellite communications, emergency beacons and computer technology stretch the communications zone so that units remain connected and personnel can be located.”
This handheld device from Trimble can calculate NDVI (Normalized Difference Vegetation Index) – an indicator of the health of a section of a field. The sensor emits brief bursts of red and infrared light, and then measures the amount of each type of light that is reflected back from the plant. The NDVI readings from across the field can be fed into the Connected Farm Scout app to calculate levels of fertilizer applications.
“A recent Google report revealed that 84 per cent of smartphone shoppers use their devices to help them browse while in a store,” said Jonathan Berlin, co-founder of Iconeme, the company that created VMBeacon.
“The technology we have developed aims to tap into this trend and offers real value to both retailers and consumers. Installing this technology in mannequins ensures it occupies a prime location and an ideal focus-point for shoppers, whether they are in the store itself or just passing by the window.”
(San Francisco’s Bait Bike) program recently got funding to place the GPS transmitters and RFID tags in a number of inexpensive and high-end bicycles owned by the department. The bikes are then chained or locked on racks around the city in hopes that thieves will take the bait.
"We can track it anywhere. Inside the city and outside," said Friedman. "We can track 'em in warehouses, in closets, in cars, anywhere."
Police and cycling advocates on Wednesday received 30,000 bright yellow and black stickers that blare "Is This A Bait Bike?"
The plan is to distribute the business card-sized labels to thousands of cyclists in the coming days and weeks in hopes of confusing would-be thieves.
