Car eye-tracking system wakes you before you crash

Sunday, November 28th, 2010

Car-dashboard-eyetracker

Falling asleep while at the helm of a few tons of metal and plastic going 60 miles-per-hour doesn’t end well, but there’s little the modern car can do about it. If it, say, stopped itself suddenly it could become a hazard to other drivers. The Eyetracker system knows it’s not on the car, though — it’s on you to drive safe.

With that in mind, the German-based Eyetracker watches the driver’s face for telltale signs of sleepiness, and issues a warning if it looks like you’re about to doze off. The system uses two cameras to keep tabs on the spatial positioning of the pupil and the line of vision — which would waver if you’re about to pass out. In other words, it makes sure your eyes are on the road.

What’s really exciting here is how small and easy to install the system is, which could see it put to use in ways other than keeping drivers awake (a noble cause, to be sure). Despite the picture above, the Eyetracker doesn’t need a laptop to function, and its control unit is the size of a matchbox. What’s more, it can be installed in any car as it handles all of its own processing itself.

Beyond just the automobile world, the Eyetacker could aid in medical operations where being able to keep on eye on — well — an eye is essential, or even in video games, serving as a head-tracker that lets the player look around without the aid of a physical controller.

Wirelessly Automate Your Home

home-automation-via-router.png

I’ve stumbled across this quite simple idea of home automation using Wifi. [Mrx23] combined OpenWRT, a microcontroller, and a set of RF controlled outlet switches to add automation to his plug-in devices. An RF remote that controls the switched outlets has been connected to an Arduino. The router communicates with the Arduino via a serial connection. And the router is controlled by a web interface which means you can use a smartphone or other web device to control the outlets.

The best thing about this system is the power that the router wields. Since it has an underlying Linux kernel you have the option of setting CRON jobs to turn lighting on and off, and group settings can be established to set up a room’s lighting level for watching movies, hosting guests, etc. Combine this with the fact that OpenWRT can use port forwarding for Internet control and the possibilities really start to open up.

DIY Arduino water meter with iPad display

Saturday, November 6th, 2010

TEAGUE Give Water from TEAGUE on Vimeo.

It’s another arduino stuff to be working on here. All related references are included:

Some of the folks over at Teague Labs have been noodling around with measuring water consumption. They’ve built a graphing water meter using a YellowJacket Arduino board with built-in WiFi and coolant flow meter from a PC cooling system to see how they used water around the office. Water conservation is major concern in many areas around the world. Tools that allow us to observe and correct our behaviors help us towards a path to sustainability. Schematics and source code are available if you want to try it out for yourself.

As for me this category is going to be my future project, so I would like to add this as a new category. I think, it would be more convenient to access all home and building automation related articles by this unique category. And as been mentioned in previous post, Home automation, a buzz word? This category will covers articles related as follows:

  • efficient energy management
  • security and surveilance
  • news and entertainment
  • drainage and watering monitoring system
  • alternative energy

A brief about Smart Home

Thursday, October 14th, 2010

Smart Home is an intelligent and easy-to-use home management system that offers a richer set of home services by allowing appliances to interact with each other seamlessly. Capabilities of appliances are used as “Lego Kits” that can be mixed and matched to provide different home services for security, well-being, energy management and entertainment.

  • Built upon open communication UPnP standards.
  • “Lego Kits” to provide services to the home user.
  • A single user interface to manage appliances and customize home services.

Brief Introduction
The Smart Home project’s objective is to develop a reference implementation of a smart home system. This implementation utilities the Uninersal Plug n Play (UPnP) standard that has been adopted by major consumer electronic (CE) manufacturers as the emerging standard for device interoperability.

UPnP is an open standard (www.upnp.org) and its adoption by the CE industry consortium such as the Digital Living Network Alliance (DLNA) (www.dlna.org) augurs well for the end consumer. Home solutions (devices, system etc) will no longer be stovepipe (proprietary, single brand) in nature, as an open standard will ensure a common playing field and consumers will be free to choose amongst the various brand offerings.

Motivation
The following set of current problems/opportunities form the basis of the motivation underlying this project.

  • Devices are standalone in nature and typically do not communicate with other devices.
  • Due to the above (1), devices cannot cooperate/collaborate to jointly provide a richer set of services to the consumer.
  • Devices are difficult to setup and configure.
  • Even if (3) was made simple, it is difficult to pair devices and provision services.
  • Home networks are becoming more pervasive. Such networks are not just confined to ICT equipments (computers, printers, access point etc). Typical home devices/equipment such as lamps, stereo set, television etc will be part of the home network.

IBM research on network of earthquake detector and locator

Wednesday, September 22nd, 2010

Computer servers in data centers could do more than respond to requests from millions of internet users. IBM researchers have patented a technique using vibration sensors inside server hard drives to analyze information about earthquakes and predict tsunamis.

“Almost all hard drives have an accelerometer built into them, and all of that data is network-accessible,” says Bob Friedlander, master inventor at IBM. “If we can reach in, grab the data, clean it, network it and analyze it, we can provide very fine-grained pictures of what’s happening in an earthquake.”

The aim is to accurately predict the location and timing of catastrophic events and improve the natural-disaster warning system. Seismographs that are widely used currently do not provide fine-grained data about where emergency response is needed, say the researchers. IBM’s research is not the first time scientists have tried to use the sensors in computers to detect earthquakes.

Seismologists at the University of California at Riverside and Stanford University created the Quake Catcher Network in 2008. The idea was to use the accelerometers in laptops to detect movement. But wading through mounds of data from laptops to accurately point to information that might indicate seismic activity is not easy. For instance, how do you tell if the vibrations in a laptop accelerometer are the result of seismic activity and not a big-rig truck rolling by? That’s why IBM researchers Friedlander and James Kraemer decided to focus on using rack-mounted servers.

“When you are looking at data from a rack that’s bolted to the floor, it’s not the same as what you get from a laptop,” says Kraemer. “Laptops produce too much data and it’s liable to have a lot of noise.”Servers in data centers can help researchers get detailed information because they know the machine’s orientation, its environmental conditions are much better controlled, and the noise generated by the device tends to be predictable.

Brilliant SCADA System that failed

Sunday, September 19th, 2010

A friend of mine shared an article about software failures. it’s a good stuff to read, where we can avoid some mistakes that previously been made by software developers. there is a SCADA software there – some of the problems that I’ve been encountered too in my life. check this out:

http://images.nakedmaya.com/Troll-Link1-sm.jpgNet-Herald – a monitoring application for water supply companies. It was a complex client server application that would receive monitoring data from specialized hardware and store that data inside a SQL database. The client displays that data in different graphs, provides printable reports or sends alarm messages via SMS if a monitored value is not within its specified limits. I developed Net-Herald as a perfect fit for that specialized hardware that is provided by a local manufacturer. That way, so I hoped, I could profit from their sales leads and would find a smoother way into these water supply companies. The downside of course, was that my software would only work with their hardware. (more…)

Home automation, a buzz word?

Friday, September 17th, 2010

Doing my routine jobs at my workplace, I stumbled upon some articles regarding home automation. It’s an old stuff actually, but I’m sure it will be interesting to read. I’ll share it later with you guys. It’ll be a busy weekend gathering enough points for this issue. There are some criterias to be covered when talking about home automation:

  • efficient energy management
  • security and surveilance
  • news and entertainment
  • drainage and watering monitoring system
  • alternative energy

If you have any other ideas, that some stuff are related to this issue. Just tweet it to me: @diblos

With iPad, home automation would be much easier system to be installed and implemented – and the price would be more affordable.

iPort has introduced two new products in its Control Mount Series for the Apple iPad and iPod touch.  The CM2000 Control Mount for iPad and the iPort CM100 Control Mount for iPod touch both integrate the handheld Apple touchscreen products in an in-wall frame, transforming them into in-wall touchscreens for display of weather, news, stocks and many other preferred Apps.

The CM100 also transforms the iPod touch into an in-wall Internet radio source, and connects to any stereo or audio/video receiver.  Users can download their choice of any Internet radio apps available in the Apple App Store and play the audio back through any connected stereo system.
The CM2000 (US$499) and CM100 ($250) may be installed in either a vertical or horizontal orientation, depending on the functionality and design of the room.  When installed into the iPort, the iPad and iPod touch remain constantly charged.

Arad Metering Technologies Conserves Water via Battery-Operated Drones

Sunday, August 22nd, 2010

The word drone may sounds related to any contemporary sci-fi flicks, or images of attacks carried out remotely on hostile lands, or even your high-school biology teacher’s voice. We don’t expect a drone to help us save water, but that’s what Arad Metering Technologies intends to do. The Israeli company’s battery-operated drone is one of the novel tools it’s deploying to help consumers and companies conserve H2O — and to make money.

Such an idea would come out of Israel is no coincidence. The country is poor in water and rich in tech innovation, much of it born of constant military conflict. Israel pioneered the use of unmanned aerial vehicles after it lost many fighter jets in the 1973 war. But Arad’s drones don’t fight: They read data from the company’s patented water-meter system to detect leakage or, in irrigation systems, drought.

The World Bank estimates that water wastage costs utilities $14 billion a year worldwide; in developing countries, 200 million more people could be served by the water lost to leaks and theft. Arad CEO Dan Winter says this is largely a consequence of how the business works in places where water is cheap or untaxed: “You train people to abuse water because they pay very little.”

With this innovation, instead of meter reading – it can provide real time monitoring of water supply infrastructures. Its technology can find irregularities — a pipe failure, an unusually low flow rate, or a too-constant one that could indicate a leak — in a few hours, rather than every 60 days as with a typical meter reading.

Arad’s system is built around what looks like a standard meter. The difference is on the inside, where you’ll find 3G wireless technology, a microcontroller, and 20-year batteries. Every 11 to 30 seconds, the system transmits data, which can be picked up by a drone (best for quickly covering big distances in remote areas) or by a drive-by or fixed-base reader. The data are then analyzed by computer to gauge how much water has been consumed, how much was lost, and even where tampering may have taken place. As a result, companies can save both water and man hours.

The possibilities for Arad’s services go far beyond water should be covering abilities to monitor everything from municipal infrastructure, such as traffic lights, to security-camera networks — basically any complex system prone to localized failures and waste. Arad has its own way, to proof drones could be associated with saving, not destroying; life, not death.
