On the heels of Tesla announcing a home and commercial battery product line, Mercedes-Benz unveiled its own brand of energy storage products for those with solar systems to store surplus power.
The Mercedes-Benz energy storage plants for private use are available for order now and are expected to ship in September.
The batteries were first developed for cars, but Mercedes-Benz said the energy storage units “meet the very highest safety and quality standards” for home use.
Up to eight battery modules with an energy capacity of 2.5 kWh can be combined into an energy storage plant with a capacity of 20 kWh.
“Households with their own photovoltaic systems can thus buffer surplus solar power virtually free of any losses,” the carmaker said in a statement.
What wasn’t announced by Mercedes-Benz was information about the size of or pricing for the new batteries.
In May, Tesla announced its Powerwall batteries for home use and its Powerpack batteries for commercial use. Today, Tesla CEO Elon Musk announced his company would double the power output of the Powerwall batteries but keep their prices the same.
Tesla’s Powerwall batteries will go from having a two-kilowatt (kW) steady power output and 3.3kW peak output to a 5kW steady output and 7kW peak output, Musk said. The price of the batteries will remain the same: $3,000 for the 7kW/hour (KWh) daily cycle version and $3,500 for the 10kWh backup UPS version. Total installation cost will run around $4,000, according to Musk.
Up to nine Powerwall battery units can be daisy-chained together on a wall to provide up to 90kWh of power.
The average U.S. household uses about 20 kWh to 25 kWh of power every day, according to GTM Research.
Tesla Energy’s new commercial-grade battery is called the Powerpack, and will sell in 100kWh modules for $25,000 each. Musk said the Powerpack can scale infinitely, even powering factories and small cities.
Mercedes-Benz’s batteries, being produced by subsidiary Deutsche Accumotive, are its first industrial-scale lithium-ion units, and they’ve already been tested “on the grid,” the company said.
Intel’s Security Exec Jumps Ship
Michael Fey has left Intel Security Group to become chief operating officer at Blue Coat. Blue Coat is apparently not the traditional garb of a British Holiday Camp entertainer, but apparently a privately owned network security company.
Fey was one of the few top McAfee managers to stay with the company after it was bought by Intel in 2011. McAfee is now part of Intel Security Group, where Fey had been chief technology officer. Fey said that his role at Blue Coat would be “very similar” to his old job but he was allowed to focus on the cloud and the advanced threats space more.
“Blue Coat had tremendous growth behind the scenes and now I get to focus on taking that growth and trying to get it to the billion-dollar revenue mark,” he told Reuters.
Since the $7.7 billion acquisition by Intel, McAfee has lost senior managers and key talent in technology development, research and sales. At Blue Coat, Fey will replace David Murphy, who will stay on as a strategic adviser to the board.
McAfee’s Biometric Software Coming Soon
Comments Off on McAfee’s Biometric Software Coming Soon
A McAfee security product that will use biometric technology to authenticate users will be available for download by the end of the year, said Kirk Skaugen, senior vice president and general manager of the PC Client Group at Intel, last week.
“Your biometrics basically eliminate the need for you to enter passwords for Windows log in and eventually all your websites ever again,” Skaugen said.
Further product details were not immediately available. But one of the major inconveniences in using PCs and tablets is remembering passwords, which biometrics can tame.
An average user has about 18 passwords and biometric authentication will make PCs easier to use, Skaugen said.
Biometric authentication isn’t new. It’s being used in Apple Pay, where fingerprint authentication helps authorize credit card payments through the iPhone or iPad. Intel has been working on multiple forms of biometric authentication through fingerprint, gesture, face and voice recognition.
McAfee is owned by Intel, and the chip maker is building smartphone, tablet and PC technology that takes advantage of the security software. Intel has also worked on biometric technology for wearable devices like SMS Audio’s BioSport In-Ear Headphones, which can measure a person’s heart rate.
Intel also wants to make PCs and tablets easier to use through wireless charging, display, docking and data transfers. Such capabilities would eliminate the need to carry power brick and cables for displays and data transfers. Such capabilities will start appearing in laptops next year with sixth-generation Core chips code-named Skylake, which will be released in the second half.
Do Chip Makers Have Cold Feet?
It is starting to look like chip makers are having cold feet about moving to the next technology for chipmaking. Fabricating chips on larger silicon wafers is the latest cycle in a transition, but according to the Wall Street Journal chipmakers are mothballing their plans.
Companies have to make massive upfront outlays for plants and equipment and they are refusing, because the latest change could boost the cost of a single high-volume factory to as much as $10 billion from around $4 billion. Some companies have been reining in their investments, raising fears the equipment needed to produce the new chips might be delayed for a year or more.
ASML, a maker of key machines used to define features on chips, recently said it had “paused” development of gear designed to work with the larger wafers. Intel said it has slowed some payments to the Netherlands-based company under a deal to help develop the technology.
Gary Dickerson, chief executive of Applied Materials said that the move to larger wafers “has definitely been pushed out from a timing standpoint”
What Do Smaller Controllers Mean?
If you want a wearable Internet of Things, the electronics have to be as tiny and as energy efficient as possible. That’s why a new microcontroller by Freescale Semiconductor is noteworthy.
The company has produced the Kinetis KLO3 MCU, a 32-bit ARM system that is 15% smaller than its previous iteration but with a 10% power improvement.
Internet of Things is a buzzword for the trend toward network-connected sensors incorporated into devices that in the past were standalone appliances. These devices use sensors to capture things like temperatures in thermostats, pressure, accelerometers, gyroscopes and other types of MEMS sensors. A microcontroller unit gives intelligence and limited computational capability to these devices, but is not a general purpose processor. One of the roles of the microcontroller is to connect the data with more sophisticated computational power.
The Kinetis KLO3 runs a lightweight embedded operating system to connect the data to other devices, such as an app that uses a more general purpose processor.
Kathleen Jachimiak, product launch manager at Freescale, said the new microcontroller will “enable further miniaturization” in connected devices. This MCU is capable of having up to 32 KB of flash memory and 2 KB of RAM.
Consumers want devices that are light, small and smart. They also want to be able to store their information and send it to an application that’s either on a phone or a PC, Jachimiak said.
This microcontroller, at 1.6 x 2.0 mm, is smaller than the dimple on a golf ball, and uses a relatively new process in its manufacturing, called wafer level chip scale packaging. The process involves building the integrated package while the die is still part of a wafer. It’s a more efficient process and produces the smallest possible package, for a given die size.

Toyota is recalling nearly 1.9 million Prius hybrid automobiles globally in order to fix a software glitch that could damage transistors and cause a loss of power.
Some 700,000 of the Priuses are in the U.S., according to a statement. Another 997,000 are in Japan, 130,000 in Europe and the remainder in other places around the world, according to media reports. Toyota didn’t immediately respond to a request for confirmation of those details on.
Toyota plans to tweak software in the Priuses for the motor/generator ECU (engine control unit) and the hybrid control ECU. The current settings “could result in higher thermal stress in certain transistors, potentially causing them to become damaged,” Toyota said. “If this happens, various warning lights will illuminate and the vehicle can enter a failsafe mode. In rare circumstances, the hybrid system might shut down while the vehicle is being driven, resulting in the loss of power and the vehicle coming to a stop.”
Toyota is also recalling about 260,000 2012 RAV4 compact sport utility vehicles, 2012-2013 Tacoma trucks and 2012-2013 Lexus RX 350 SUVs in the U.S., the company said Wednesday.
Toyota will apply an update to skid control ECU software on cars in this recall to fix an “electronic circuit condition” that could cause the vehicles stability control, anti-lock braking systems and traction control function to shut down intermittently, Toyota said. However, in the event of such a failure the standard brakes will still work, according to the company.
No accidents or injuries have been reported in connection with the software problems, Toyota said. The software update will be applied free of charge at local dealers.
Researchers Build Flying Robot

Comments Off on Researchers Build Flying Robot
Researchers say they have assembled a flying robot. It’s not designed to fly like a bird or an insect, but was built to simulate the movements of a swimming jellyfish.
Scientists at New York University say they built the small, flying vehicle to move like the boneless, pulsating, water-dwelling jellyfish.
Leif Ristroph, a post-doctoral student at NYU and a lead researcher on the project, explained that previous flying robots were based on the flight of birds or insects, such as flies.
Last spring, for example, Harvard University researchers announced that they had built an insect-like robot that flies by flapping its wings. The flying robot is so small it has about 1/30th the weight of a U.S. penny.
Before the Harvard work was announced, researchers at the University of Sheffield and the University of Sussex in England worked together to study thebrains of honey bees in an attempt to build an autonomous flying robot.
By creating models of the systems in a bee’s brain that control vision and sense of smell, scientists hope to build a robot that would be able to sense and act as autonomously as a bee.
The problem with those designs, though, is that the flapping wing of a fly is inherently unstable, Ristroph noted.
“To stay in flight and to maneuver, a fly must constantly monitor its environment to sense every gust of wind or approaching predator, adjusting its flying motion to respond within fractions of a second,” Ristroph said. “To recreate that sort of complex control in a mechanical device — and to squeeze it into a small robotic frame — is extremely difficult.”
To get beyond those challenges, Ristroph built a prototype robot that is 8 centimeters wide and weighs two grams. The robot flies by flapping four wings arranged like petals on a flower that pulsate up and down, resembling the flying motion of a moth.
The machine, according to NYU, can hover and fly in a particular direction.
There is more work still to be done. Ristroph reported that his prototype doesn’t have a battery but is attached to an external power source. It also can’t steer, either autonomously or via remote control.

Scientists have discovered a way to power future robots using an unusual source — urine.
Researchers at the University of the West of England, Bristol and the University of Bristol collaborated to build a system that will enable robots to function without batteries or being plugged into an electrical outlet.
Based on the functioning of the human heart, the system is designed to pump urine into the robot’s “engine room,” converting the waste into electricity and enabling the robot to function completely on its own.
Scientists are hoping the system, which can hold 24.5 ml of urine, could be used to power future generations of robots, or what they’re calling EcoBots.
“In the city environment, they could re-charge using urine from urinals in public lavatories,” said Peter Walters, a researcher with the University of the West of England. “In rural environments, liquid waste effluent could be collected from farms.”
In the past 10 years, researchers have built four generations of EcoBots, each able to use microorganisms to digest the waste material and generate electricity from it, the university said.
Along with using human and animal urine, the robotic system also can create power by using rotten fruit and vegetables, dead flies, waste water and sludge.
Ioannis Ieropoulos, a scientist with the Bristol Robotics Laboratory, explained that the microorganisms work inside microbial fuel cells where they metabolize the organics, converting them into carbon dioxide and electricity.
Like the human heart, the robotic system works by using artificial muscles that compress a soft area in the center of the device, forcing fluid to be expelled through an outlet and delivered to the fuel cells. The artificial muscles then relax and go through the process again for the next cycle.
“The artificial heartbeat is mechanically simpler than a conventional electric motor-driven pump by virtue of the fact that it employs artificial muscle fibers to create the pumping action, rather than an electric motor, which is by comparison a more complex mechanical assembly,” Walter said.
Chip Makers Going After Cars

Comments Off on Chip Makers Going After Cars
Chip makers including Broadcom and Renesas Electronics are putting more focus on in-car entertainment with faster processors and networks for wireless HD movies and navigation, aiming to keep drivers informed and passengers entertained.
With PC sales slipping and the mobile device market proving highly competitive, chip makers are looking for greener pastures in other sectors like in-car entertainment and information.
From Renesas comes the R-Car M2 automotive SoC (System-on-a-Chip), which has enough power to handle simultaneous high-definition navigation, video and voice-controlled browsing.
The SoC is meant for use in mid-range systems. It features two ARM Cortex A-15 cores running at up to 1.5GHz and Renesas’ own SH-4A processor plus the PowerVR SGX544MP2 from Imagination Technologies for 3D graphics. This combination helps the M2 exceed the previous R-Car H1 with more than three times the CPU capacity and approximately six times better graphics performance.
Car makers that want to put a more advanced entertainment system in their upcoming models should go for the eight core R-Car H2 SoC, which was announced earlier this year. It is based on ARM’s big.LITTLE architecture, and uses four Cortex-A15 cores and another four Cortex-A7 cores.
The H2 will be able to handle four streams of 1080p video, including Blu-Ray at 60 frames per second, according to Renesas. Mass production is scheduled for the middle of next year, while the M2 won’t arrive in larger volumes until June 2015.
Broadcom on the other hand is seeking to drive better networking on the road. The company’s latest line of wireless chipsets for in-car connectivity uses the fast 802.11ac Wi-Fi wireless standard, which offers enough bandwidth for multiple displays and screen resolution of up to 1080p. Use of the 5GHz band for video allows it to coexist with Bluetooth hands-free calls on 2.4GHz, according Broadcom.
Broadcom has also implemented Wi-Fi Direct and Miracast. Wi-Fi Direct lets products such as smartphones, cameras and in this case in-car computers connect to one another without joining a traditional hotspot network, while Miracast lets users stream videos and share photos between smartphones, tablets and displays.
The BCM89335 Wi-Fi and Bluetooth Smart Ready combo chip and the BCM89071 Bluetooth and Bluetooth Smart Ready chip are now shipping in small volumes.
Sharp Shows MEMs

Comments Off on Sharp Shows MEMs
Sharp on Monday unveiled its latest prototypes of a new kind of display screen that it says brings several advantages over today’s liquid crystal display (LCD) screens.
The screens, called microelectromechanical systems (MEMS) displays for the tiny moving parts they contain, are being developed by the Japanese company in partnership with Qualcomm and were on show at the Ceatec electronics show just outside of Tokyo.
Behind each pixel in a MEMS display is a backlight that flashes red, green and blue in fast succession, and in front of it is a tiny shutter can be opened to let light through.
Synchronized to the backlight, the shutter can control the amount of each color of light allowed through. The eye perceives these flashes as the desired hue.
In contrast, today’s LCD screens create colored pixels using three filters. The filters swallow about two thirds of the brightness of the backlight before it leaves the display, said Akira Imai, deputy general manager of Sharp’s new business development center.
The MEMS display can allow all the light through, so the intensity of the backlight can be reduced using less power for the display, said Imai.
In a portable gadget, the screen often consumes more power than any other component, so reducing its demands can have a big impact on battery life.
The screens on show at Ceatec were 7-inch models with 800 pixel by 1,280 pixel resolution. The colors were bright and the screen image was sharp, although people viewing the screens did tend to see a brief flash of red, green and blue pixel each time they turned their eyes away from the display. That’s something Sharp is working on, said Imai.
Sharp also showed a version of the screen working in several low power modes.
The development work with Qualcomm began earlier this year when the U.S. company said it would invest $120 million into Sharp. The money, which was invested in two parts, was accompanied by Qualcomm’s MEMS expertise. Sharp has a long history in flat-panel display technology, especially LCD, and has recently been working on a new type of display called IGZO, on which the MEMS display is partly based.
