GM Ventures Invests in Powermat

GM logoXconomy – Detroit reports that GM Ventures, the Detroit -based car maker’s venture capital arm has invested $5 million in Powermat the Commerce Township, MI start-up. A multiyear, multimillion-dollar deal with Powermat gives General Motors (GM) exclusive rights to place the company’s portable-device charging technology in its cars for a year. according to Micky Bly, the company’s director of hybrid vehicles. The Chevy Volt and certain Cadillac models will be the first GM cars to the Powermat accessories. The New York Times reports that at this year’s CES GM demonstrated four wireless charging positions in the Chevy Volt.

GM Ventures has also invested in Indiana-based electric car startup Bright Automotive and Ann Arbor-based battery developer Sakti3. Also, see this earlier post.

Car Theft by Antenna

Keyless entryMIT’s Technology Review reports that researchers at ETH Zurich in Switzerland have successfully attacked passive keyless entry and start systems from eight different car manufacturers’. The researchers examined 10 car models from eight manufacturers. They were able to take all 10 by intercepting and relaying signals from the cars to their wireless keys because the key transmits its signals up to around 100 meters. The attack works no matter what cryptography and protocols the key and car use to communicate with each other.

The researchers tested a few scenarios. An attacker could watch a parking lot and have an accomplice watch as car owners entered a nearby store. The accomplice would only need to be within eight meters of the targeted owner’s key fob, making it easy to avoid arousing suspicion. In another scenario, a car owner might leave a car key on a table near a window. An antenna placed outside the house was able to communicate with the key, allowing the researchers then to start the car parked out front and drive away.

The researchers concluded that manufacturers will need to add secure technology that allows the car to confirm that the key is in fact nearby.

New Standard for Automotive-Grade Wireless Modules

Connected carSierra Wireless (SWIR) recently introduced what the firm calls, the industry’s first suite of embedded wireless technology modules designed specifically for automotive manufacturers. The Canadian firm is banking on the emerging trend to include telematics, infotainment, navigation assistance, and remote diagnostics in new cars within the next few years according to an article on ITNewsLink.com. The firm believes these applications will need reliable built-in connections to cellular networks. The new Sierra Wireless modules will use 2G and 3G network technologies and frequency bands used worldwide to provide the connectivity customers are demanding.

The manufacturer says these units are the first wireless modules developed from the ground up to achieve compliance with automotive specifications.  ITNewsLink.com says the Sierra Wireless AirPrime AR Series design encompasses:

  • Tolerance for up to 1,000 thermal shock cycles
  • Full certification with ISO 9001:2000 quality standards and ISO/TS 16949:2002 manufacturing processes
  • Extended operating temperature range from -40 to 85 degrees Celsius
  • Compliance with multiple automotive manufacturing and quality processes including AQPQ, PPAP, PCN, and 8D
  • Solder-down form factor and optional Embedded SIM to create a more reliable and less expensive solution
  • An open platform for custom application development, including dedicated APIs for telematics applications.

Wireless Car Sensors Vulnerable to Hackers

Wireless Car Sensors Vulnerable to HackersMIT’s Technology Review reports that hackers could “hijack” the wireless pressure sensors built into many cars’ tires, researchers have found. Criminals might then track a vehicle or force its electronic control system to malfunction, the University of South Carolina and Rutgers University researchers say. The team successfully hijacked two popular tire-pressure-monitoring systems (TPMS).

As automakers add more technology and computers to cars and connect those computers to critical components, in-car systems will need to be secured against hackers, experts warn.

The systems tested by the South Carolina-Rutgers team had very little security in place–they mainly relied on the communications protocol is not widely published. “In doing TPMS this way, [automakers] have left the door open to wireless attackers,” says Travis Taylor, one of the researchers. The team could eavesdrop on communications and, in some circumstances, alter messages in transit. That let the team give false readings to a car’s dashboard. They could also track a vehicle’s movements using the unique IDs of the pressure sensors, and even cause a car’s ECU to fail completely.

“Normally, these [attacks would] result in small problems,” Mr. Taylor says. “But I see practical danger and damage that can happen from TPMS exploitation.” “The security and privacy problems that the researchers identify in TPMS systems are likely just one among many that will challenge the automotive industry in the years to come,” says Stefan Savage, a UC San Diego professor of computer science and engineering.

Ford Installs Sync Software via Wi-Fi

Ford Installs Sync Software via Wi-FiThe Detroit Bureau reports that Ford is the first automaker to use Wi-Fi to send software to vehicles along an assembly line. The automaker is sending infotainment software to Wi-Fi enabled MyFord Touch-equipped vehicles like the Edge.

Ford installed  Wi-Fi technology at its Oakville, Ontario, plant where it builds the Ford Edge and Lincoln MKX. Next up for Wi-Fi updates will be the upcoming Ford Explorer, built in Chicago, and then plants that build the Focus around the world.

Wi-Fi capability eliminates the need for building, stocking multiple SYNC hardware modules, thus reducing manufacturing complexity and saving cost.  “Using wireless software installation via Wi-Fi, we can stock just one type of SYNC module powering MyFord Touch and loaded with a basic software package,” explained Sukhwinder Wadhwa, SYNC global platform manager. “We eliminate around 90 unique part numbers, each of which would have to be updated every time a change is made – this system really boosts quality control.”

“Turning an assembly plant – with steel beams everywhere and high-voltage cabling throughout; everything you could imagine that would interfere with a radio signal – into an access point that would achieve 100 percent success was a huge challenge,” Mr. Wadhwa said.

Wireless Charging Amped Up

Wireless Charging Amped UpThose of us tired of dealing with tangled cord and bulky wall warts may get some relief in the near future. iSuppli Corp. is predicting that a flood of new electronic gizmos with wireless charging capabilities will be inundating the market. The market research firm believes that the global market for wireless charging devices for smartphones like the RIM (RIMM) Torch, tablet computers such as the Apple (AAPL) iPad2 media players like the Apple iPod Touch will drive the global market for wireless charging devices to 234.9 million units in 2014, up 65% from 3.6 million in 2010, according to iSuppli.

iSuppli table Tina Teng, senior analyst for wireless research at iSuppli told Itnewslink.com, “Over the next five years, wireless charging devices will find their way into an increasing number of applications, including mobile phones, portable media players, digital still cameras, and mobile PCs.”

Mobile phones will drive wireless charging acceptance according to Ms. Teng, ” …mobile phones will contribute the largest share of revenue to wireless charging-not only because of the large volume of mobile devices expected to benefit from the technology, but also because of participation by name brands in manufacturing the device, providing much-needed market recognition in the process.”

“Genius of Electricity,” 1915, Gilded Bronze, Bedminster, NJ. Photography Lee sandstead"Despite the optimism, iSuppli believes there are still barriers to the widespread adoption of wireless charging. Manufacturers will have to make wireless charging in their devices down to the circuit board level which will drive down costs. The wireless charging industry will need to adopt a common standard to ensure interoperability among products. Currently, all products are proprietary. Skins made by one company, will not work with the charger pad of another. “Until the industry finds a standard to follow, the wireless charging industry will be fragmented, and consumers will hesitate to adopt any solution that could be compromised by the rival companies,” Itnewslink.com quotes Ms. Teng, “However, an open, standardized system will create a healthier competitive environment and prompt manufacturers to join forces-which will enhance consumer awareness and lead to adoption in the markets.”

There are four wireless charging technologies. The wireless charging technologies include Near-field magnetic resistance, Far-field magnetic resistance, Conductive magnetic resistance, and Inductive magnetic resistance wireless charging systems.

  • Far-field magnetic resonance, a technology that has raised safety as well as health concerns and for which no commercial products are available for the time being.
  • Inductive wireless charging uses the principle of electromagnetic induction where current generated from the induced magnetic field in the receiver coil charges devices is the most widely wireless charging technology adopted by the value chain.  the technology enjoys wide support from semiconductor vendors, device manufacturers, accessories makers as well as retailers according to the Wireless Design and Development website. The most successful proponent of magnetic induction is Powermat, a Michigan-based company which I wrote about in 2010, that also owned 62 percent share of the wireless charging market as reported by Wireless Design and Development.

iSuppli notes that most companies are not ready with commercial products yet, several high-profile manufacturers are looking at producing wireless charging solutions. The companies include Texas Instruments (TXN) and ST-Ericsson from the semiconductor side; Nokia Corp (NOK) and Research In Motion Ltd. from the device manufacturer side; and Logitech (LOGI) and Case-Mate from the accessory manufacturer side.

Product-specific wireless charging systems consist of a charger as well as a so-called “skin” or receiver sold for specific devices. These product-specific devices contrast with aftermarket solutions, which are universal chargers and various skins that can be used with multiple consumer electronics. Growth is also projected for aftermarket wireless charging, with revenue rising at a massive five-year Compound Annual Growth Rate (CAGR) of 133.4 percent.

Rats nest of cablesrb-

I hate the cluttered cluster of cables on my desk. The wireless chargers should clean up that mess, but until the manufacturers get their act together and build in some interoperability from the factory, they still got a problem.

What do you think?

Is wireless charging a practical technology?

Do you have a wireless charging rig?

Wi-Fi Harvester

Wi-Fi Harvester Computerworld reports that RCA demonstrated a prototype device that converts Wi-Fi radio signals into DC power to charge wireless devices. The W-iFi Hotspot Power Harvester, also known as Airnergy, was shown at the 2010 Consumer Electronics Show. RCA’s device was able to charge a BlackBerry Bold with about 30 percent power in 90 minutes using Wi-Fi access points located nearby, according to an RCA official recorded on video by Geeky-Gadgets.com. The amount of charging time depends on a user’s proximity to the Wi-Fi hot spot.

The Airnergy unit stores the charge in an internal lithium battery, so you don’t necessarily have to be in a Wi-Fi hot spot to recharge your device. The device is about 2 in. by 3 in. in size and will sell for $39 to $49 this summer. RCA said it is developing a smaller version that would replace a battery inside a hand-held device and sell for about $60. That smaller version could ship in 2011.

Other wireless chargers

Demonstrations of wireless chargers have been a staple of CES for several years, and some products promised in 2008 have not materialized. Some products, such as the Dell Latitude Z laptop, allow charging by placing the laptop directly on a wireless charging stand. Fulton Innovation LLC, (I wrote about here) showed products and prototypes at CES. One Fulton technology concept powers a 12-watt light bulb from a transmitter placed 35 inches away. Powermat USA showed new wireless charging mats for handheld computers at prices ranging from $39 to $149, and the company’s CEO said Powermat has sold 750,000 devices since the company launched two months ago.

There is much skepticism over this product. The inverse-square law roughly says in this case that the signal would decrease in intensity inversely proportional to the square of the distance. Double the distance and signal strength drops by a fourth and so on. Thus at the distance at which most people find themselves from access points, the amount of energy available is minute.

Here is an article from SensorMag.com that describes how RF energy harvesting works.
