Tasker (App for Android

 

Tasker

android app

What if your phone automatically went silent when you step into the movie theater? Texted your significant other when you finished your long commute? Or automatically turned down the volume when a particularly loud friend called? It can; here's how.

 

Android application Tasker gives you total rules-based automation for your Android phone. It's not free, but it offers a free 14-day trial download. In the Android Market, it's £3.99 in UK money—a little over $6 U.S. If you grab the trial, or shell out the cost of a Double-Double meal at In-N-Out Burger to buy it in the Market (scan the QR code at left), you'll discover it's worth the cost, even if you only have one super-specific use for it.

One of the reasons for Android’s popularity is its flexibility and the ability to install all kinds of apps and software mods to it. Now, there are tons of apps that do everything from helping you manage your time to reading news, but there are some more apps that let you do interesting things on your phone. Tasker is probably at the top of this and is considered to be one of the world’s top Android apps.

"TASKER"  contains different profiles for doing specific task

1. Silencing your phone by placing it face down using TASKER

Anyone who has used an HTC Android device will know that one of the coolest features of the custom user interface is the ability to silence your phone's ringer, simply by flipping it face-down on a flat surface. If you've suffered excruciating embarrassment from your Crazy Frog ringtone sounding off during a business meeting, you'll appreciate this.

With Tasker, any Android device can have this function. Start up the app and you'll be presented with the Profiles screen. It's here that all of your Tasker profiles appear, but it will obviously be blank at this juncture as you haven't created one yet. Tap the '+' icon to bring up the profile creation menu and give it a name -- something like 'Ringer silent' will do.

Next, you'll have to select the context for the profile. This is basically the trigger that will cause the profile to become active. Select 'Event' and then 'Sensor'. We want the phone's ringer to go silent when the phone is placed face down, so select 'Orientation' and then 'Face down' from the next menu.

We've given the profile a context, but now we need to assign a task that will be executed when the context is met. Select 'Audio' and then 'Silent Mode'. Toggle the setting to 'On' or 'Vibrate', and you're golden. The next time when your handset rings when it shouldn't, you can just flip it over and spare your blushes.

2. Dim your screen when the battery level is low

Tasker is clearly very useful for automating fiddly processes on your handset, but it can also be used to conserve precious battery power. In this step, we're going to create a profile that automatically drops your screen brightness down when the battery juice dips below a certain point.
Create a profile and name it whatever you wish -- you've got the hang of that by now, right? Select 'State', 'Power' and then 'Battery level'. The following screen has two sliders -- the first represents the lowest power level (so set it to zero), and the second is the highest. Set that at around 15-20 per cent and click accept.

Name the task 'Dim Screen' or something similar, and then select 'Display' and 'Display Brightness'.

Dropping the value down to around 10-20 per cent will make the screen very dark, but still legible. It will save you a surprising amount of battery power. If you have auto-brightness enabled, you'll need to turn it off -- Tasker will remind you of this fact at the end of the process.

As with the Auto-Sync profile, you'll need to create an exit task to tell Tasker to pump the screen brightness back up to your preferred level when the battery is topped up.
This profile could potentially offer up many minutes of additional power. It's something of a godsend when you're away from home and don't want your S2 dying on you. For additional juice, you can add in additional tasks to the low battery level context, such as switching off mobile data.       and guys u knw how to download a priced app in google play........ just search for tasker apk...........

Power to Electricity

 Breathing Power to Electricity......


           One of the biggest hurdles facing the developers of biological implants is coming up with a power source to keep the implanted devices ticking. We've seen various technologies that could be used instead of traditional batteries (which require the patient to go under the knife so they can be replaced) such as wireless transmission of power from outside the body, biological fuel cells that generate electricity from a person's blood sugar, and piezoelectric devices that generate electricity from body movements or the beating of the heart. Now researchers have developed a device that could be used to generate electricity from a patient's breathing.

            The device created by researchers at the University of Wisconsin-Madison relies on the piezoelectric effect - whereby an electrical charge accumulates in certain materials in response to mechanical stress. But instead of relying on body movements to create the mechanical stress, the UW-Madison team's device uses low speed airflow like that caused by normal human respiration to cause the vibration of a plastic microbelt engineered from a piezoelectric material called polyvinylidene fluoride (PVDF).
          "Basically, we are harvesting mechanical energy from biological systems. The airflow of normal human respiration is typically below about two meters per second," says Materials Science and Engineering Assistant Professor Xudong Wang who created the device along with postdoctoral researcher Chengliang Sun and graduate student Jian Shi. "We calculated that if we could make this material thin enough, small vibrations could produce a microwatt of electrical energy that could be useful for sensors or other devices implanted in the face," said Wang.

          To thin the PVDF material to micrometer scale while preserving its piezoelectric properties, Wang's team used an ion-etching process. Wang believes that, with improvements, the thickness of the material, which is biocompatible, can be controlled down to the submicron level and lead to the development of a practical micro-scale device that could harvest energy from the airflow in a person's nose.

Online Banking fraud Case

  

New system to combat online banking fraud

       A security solution which protects against the most serious threat to online banking customers, responsible for millions in annual losses, is being rolled out across Europe by a Cambridge University spin-out.

      A Trojan horse is a type of malware which, like its namesake, presents itself as a harmless gift in order to persuade users to install it, appearing as a legitimate software program. Once installed, hackers gain access to the computer in order to steal information or harm the system.
      

      The solution developed by Cronto protects against Trojan attacks by using a visual channel to transfer data securely from the bank to the customer. It allows the bank to generate a pattern of coloured dots – a proprietary two-dimensional barcode containing the data which the bank is trying to send to the customer, which is decoded by the customer using Cronto's mobile application or standalone hardware device. The company's technology provides a secure "envelope" around the data so that it can be displayed to the customer on a trusted display for verification in any environment over any unsecured channel. The Trojan can see the image being sent by the bank, but cannot change the secure data inside.
    
       Trojan attacks are prevalent and growing. Security firm McAfee identified more than 1.5 million different Trojan malware variations in 2012, with financial services websites a popular target. Trojans are especially dangerous as they control both what the bank receives from the customer and what the customer sees in their browser – a type of attack known as Man-in-the-Browser.
       
       According to Igor Drokov, Cronto's CEO, security in the world of online banking has to go beyond identifying who a customer is, whether via a password, the street they grew up on or the name of their pet goldfish.
    
       "That's not enough, he says. "To combat the level of sophistication poised by Trojan malware, the bank also needs to verify the action that the customer is trying to perform, whether it's a purchase, a transfer or a change of address." Cronto's aim was to produce a solution that was easy to use for millions of customers, but robust enough to meet the security challenges faced by banks.

       The 2D barcode which the team developed allows the bank to securely transfer a message of over 100 characters that is decoded by the company's application or hardware device in fractions of a second. The specific features of the image have been developed by testing machine learning algorithms on large datasets of images captured in different conditions.
    
        Using the application or hardware device, the customer scans the image. Providing the security conditions are met, the customer will see the message from their bank, which is typically asking them to confirm the action they are attempting to perform, highlighting any aspects of the transaction which are out of the ordinary. To confirm the transaction, the customer simply uses a six-digit code, generated by the app or device, and enters it into their browser. The code acts as the customer's signature for this specific instruction, and once received and validated by the bank, completes the transaction.

      The technology can be used in any environment and is highly adaptable, as it gives the banks the ability to change the message they wish their customers to see, whether in response to an emerging security threat, or simply to allow the

         While Cronto is currently focused on the online banking sector, the team also sees commercial possibilities for their technology in e-commerce, peer-to-peer online payments, or any other application where there is a need to create a trusted connection between two parties.

Tablet Technology

Tablet Technology --- Mobile development Training.

               The recent announcement of the new iPad has, like any Apple release, set the tech world ablaze with speculation and anticipation. There's no denying new technology like this can vastly improve many areas of a business' operations, particularly when it comes to workplace training. However, one of the new iPad's less known benefits has less to do with that model and more to do with other models of tablets.
             
               The new iPad means the likelihood is high the price of the original will experience a significant drop. The iPad 2 will apparently cost at least $399, placing it $100 above the current model. If history is any indication, that gap will widen after the new iPad hits stores by the end of 2012. As such, companies interested in Apple app development and other mobile workplace training should begin planning their instructional programs for the upcoming year. It also means that other non-Apple devices will soon either be discounted or released with lower prices.
           
                Tablets make excellent mobile development training tools because they're incredibly versatile. They don't just have to be training platforms – tablets also have several workplace applications that come into play after new hires have become full-time members of your staff. In fact, many organizations are implementing bring-your-own-device (BYOD) policies when it comes to tablets, rewarding workers who provide their own technology for training and job-related activities. Consider starting such a program and even subsidizing iPad purchases (if the prices indeed fall) to supplement your mobile app development training efforts.

Touch Screen Technology

How does Touchscreen technology work 

Touchscreens treat all fleshy finger pads alike: Most detect a simple change in electrical current or in sound or light waves regardless of who is swiping. Researchers at Disney Research, Pittsburgh, have built a touchscreen that can discriminate between users. Every person’s body has its own bone density, muscle mass, blood volume, and water content. The device, called Touché, sends a series of harmless currents through a user’s body. Physiological differences produce differences in the body’s impedance of that current. Touché measures this unique capacitive signature. Scientists could apply capacitive fingerprinting to any touchscreen, or to other ubiquitous objects, such as doorknobs and furniture, turning the world into an interactive device. Touché is still in development, and plans for commercialization, alas, are top secret.
A) INDIUM TIN OXIDE
Capacitive sensors found in most existing touchscreens, track pads, OLED displays, and other electronics use indium tin oxide (ITO) as an electrode. The conductive material transmits an electric current to a user’s fingertips. ITO is also transparent, so light from the underlying LCD screen shines through.
B) SENSOR BOARD
The sensor board injects tiny electric currents into the ITO layer. When a user touches the screen (and thus the ITO layer), current flows from the sensor board through the ITO to the person’s body. The sensor on the board measures the body’s unique impedance at multiple frequencies. The most recent prototype takes up to a second to recalibrate for each new user. Once calibrated, it can recognize a familiar body in 500 milliseconds.
C) LCD PANEL
An LCD provides the touchscreen's graphical interface

I've got the multi-touch

Despite the growth of touchscreens in all kinds of devices, a major advance in Apple's iPhone was its use of multi-touch technology that allows sensors to pick up more than one fingerpress at a time. This is also possible using optical imaging, but the apparatus and image-processing required for that type of touchscreen are far too onerous for a portable device; this has led to broad use of an alternative known as 'mutual capacitance'.

Browser Wars

 Browser Wars Continue

            As more applications move to the web, your browser stays front and center throughout most of your computing experience. In many cases the browser is also tightly integrated with the host OS as well.             While each browser can get you on the web, and for the most part provide you with an experience that the web master intended, there are enough differences to warrant some investigation before you decide on which will be your primary gateway to the Internet. Fortunately, competition is stiff and the browser vendors are constantly improving their respective experiences.
The main factors to consider are:

• Does the browser work well with your OS?
• Are the websites you visit or value most supported by the browser?
• Do you require certain plugins/add-ons to get your work done?
Fortunately, all of the browsers are free, so cost is not a factor in your decision. You can also install all of them on your system and give them each a test drive. Note that for Internet Explorer 10, you will need a [virtual machine], if you are not running a Windows PC.
Take a moment to check out the latest features on the most popular browsers:

• Chrome
• Internet Explorer 10
• Firefox
• Safari 

           Which of the above trends will have the most impact on your life?

3D technology that'll change the Science View

Upcoming 3D technology to make science fiction a reality

       

Science fiction till now was a part of films, but with upcoming 3D technology, it will become as palpable as the reality that surrounds you. You can take a ride in to a human brain, universe or ocean and more, just by wearing 3D Glasses. Thanks to the Computer scientists at the University of Illinois at Chicago, who are pushing science fiction closer to reality with a wraparound virtual world.

This technology is known as CAVE2, where a screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, gives you a strong sense of being able to touch them.

Scientist in many fields are striving to truly understand overwhelming amount of data. Jason Leigh, co-inventor of the CAVE2 virtual reality system, believes this technology answers that challenge.

"To do science in this kind of environment is absolutely amazing."

Type in Air for a Computer...!!!

Writing Without Keyboard: Handwriting Recognition On the Wrist

Typing text messages on the mobile phone via the tiny soft keyboard is very cumbersome. How about simply writing it into the air! This idea drove the development of "airwriting" made by computer scientists of Karlsruhe Institute of Technology (KIT). Sensors attached to a glove record hand movements, a computer system captures relevant signals and translates them into text.

The system offers a new interface for wearable computing applications. These are computer systems worn like clothes, which can be integrated seamlessly into the everyday life of the user. "Information technology is used any time and anywhere, but smart phones are still working on the basis of virtual keyboards and small screens. However, gestures allow for new types of input -- in particular for mobile devices or devices integrated in clothing. The interaction is embedded seamlessly in everyday life".

"The airwriting glove is used to write letters into air, as if using an invisible board or pad."
For this purpose, acceleration sensors and gyroscopes are attached to the thin glove. Contrary to systems based on cameras, these sensors are very small, mobile, and robust. They record the movements of the hand and transmit them to a computer system via a wireless connection. The computer system first checks whether the user is indeed writing.

Nano Technology

Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic and molecular scale. Generally, nanotechnology works with materials, devices, and other structures with at least one dimension sized from 1 to 100 nanometres.

Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to direct control of matter on the atomic scale. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.

Scientists currently debate the future implications of nanotechnology. Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and governments on whether special regulation of nanotechnology is warranted.
