Google intant now on iphone and android

November 7, 2010

Google Instant has now become available on mobile phones currently on iphone and android.

Now Google searchers using the iPhone and/or Android phones will start seeing Google Instant show up on their devices by now.According to Google it’s a beta release, meaning Google doesn’t want you to get mad at them if it doesn’t work exactly right, and unlike the desktop version, you have to turn it on in order to see results as you type. It only works at Google.com in your mobile browser, but not in any of the other search boxes.

This is theoretically a good step to mobile searches, because typing on a mobile device is far more annoying than typing on a full-size keyboard as mobile’s keypad size is small. The keypad on several touch-screen mobile phones takes up nearly half the screen on its own, and the drop-down box that produces suggested Google Instant results further reduces the page available for the search results page itself.You’ll need to be running iOS 4.0 or Android 2.2 in order for this to work, Google said.

Holography

October 30, 2010

what is holography and hologram?

“We call the process as holography while the plate or film that is
build in consequence of this process is called hologram.”

Holography is one of promising technique for recording & displaying  3D objects.It enables to view 3d photos in virtual reality, play 3d games, and watch 3d TV as if we are actually present in that environment.

Holography is true 3d display technology. This technology is more
popular and effective as it provide all four eye mechanism,

(1) Binocular Disparity: Is the difference between two retinal images and tells brain about depth. This difference is greater when object near to eye. E.g. hold your arm straight in front of face and focus on tip of finger, to see disparity in two images you see, look at your finger first from one eye and then from second eye, surely  you will feel difference. Repeat the same process but see arm from distance, and compare all four views u see.

(2) Motion Parallax: provide cues to difference in the distance of
various objects.E.g. you are driving car, notice objects which are nearer to u whiz by those objects that are at distance which move slowly.

(3)Accommodation: Is the process where we maintain our focus on object as it changes distance.

(4)Convergence:It is simultaneous inward movement of both eyes toward each other, usually to maintain single binocular vision (seeing an object with both eyes). E.g. Try to focus on the end of nose; you will feel strain during when u focus it, while during slow shift your muscles will feel relax.

Unlike other 3-D “pictures”, holograms provide what is called
“parallax”. Parallax allows the viewer to move back and forth, up and down, and see different perspectives, as if the object were actually there.

Latest ECG-Equipped Smartphone Could Save Lives, Minimize Hospital Visits

October 28, 2010

A new German smartphone is equipped with monitoring a patient’s heart and send information directly to doctors without any hurdle, and in this way decreases risks and reduces health care costs.

Now adays most of the deaths occur due to the heart disease according to a report about 30 percent of deaths across world occur due to heart disease, so in such a situation Patients must
carefully monitor their heart health with frequent visits to the doctor. The most important test for people suffering from cardiovascular disease is the electrocardiogram (ECG), a diagnostic
tool that measures the electrical activity of the heart. Unfortunately for most patients, ECGs are expensive and, since they are taken sporadically, provide only a small snapshot of cardiovascular health.

So to overcome this problem for poor people the new smartphone, called H’andy Sana 201, contains a rapid ECG tool that measures and records heart activity then it sends text messages data directly to patients’ doctors, who can quickly respond to any concerns according to data. The smartphone measures and records the heart’s electrical impulses using three sensors .

Just like a hospital’s ECG test, the H’andy Sana 201 measures the electric pulses sent through the body by the heart. To use, a patient presses his/her fingertips to the phone’s steel frame, which contains three sensors. The phone has calibration barriers to prevent the sensors from picking up movements from the arms and shoulders. It’s also designed to ignore frequencies above the heart’s estimated 150 hertz. The phone’s processor uses algorithms to extract the heart’s rhythm, which the patient can then transmit directly to the doctor.

GPU(Graphic Processing Unit)

October 14, 2010

What is GPU?

GPU is a a single chip processor with integrated transform, lighting, triangle setup/clipping, and rendering engines that is capable of processing a minimum of 10 million polygons per second.”

Purpose of GPU

As computations are increasing day by day and there is allot of load on general purpose CPU , and further if a user does graphic processing then due to huge load the general purpose CPU gets slow down and graphics are also not displayed as per the desire of user so to make independent general purpose CPU from graphic processing and display the graphics in good form this GPU is used hence the load over CPU is decreased and also user have a good graphics which is shown by this picture .

this picture shows that you can get realism by GPU further GPU can effectively process the 3D graphics which is used mostly now adays
