Secret features of smartphone must be known

Smartphone has some features that many users are not aware of, but these are very effective. These features can be of great help even in times of danger. Let us now know some of the features and tricks that are very effective. 

There is no need to turn off the video if you want to click a picture during make a video on smartphone. The iPhone also displays an icon of the photo while taking video, in where if you click it will capture pictures at the time of video being recorded. 

Many times the remote of the television, speaker or device at home goes bad, to know whether the remote is really damage or not, it can be known through the smartphone. Just place the remote sensor in front of the phone's camera and press the remote button. If the light on the remote sensor blinks, it indicates that the remote is OK and if the light does not blink, then it ensures of damaging condition of remote. 

Smartphone has a very good feature if you want to read any text on the screen when your eyesight is poor; which is called magnification. With this feature different parts of the screen can be zoomed. For this you have to tap the screen three times, it will zoom the screen. 

Nowadays smartphone has the feature of macro lens, which can take pictures of very small objects. Through this, the camera lens can be made more zoomed and smaller objects can be seen in larger resolutions without zooming.

Smartphone headphones are not only useful for listening to music, but also for taking pictures. Although this feature is not present in the earphones of all smartphones. However, it can be verified whether the smartphone has this feature or not. Source: https://www.daily-bangladesh.com/

Smartphones uncover how the world sleeps

A pioneering study of worldwide sleep patterns combines math modelling, mobile apps and big data to parse the roles society and biology each play in setting sleep schedules. The study, led by University of Michigan mathematicians, used a free smartphone app that reduces jetlag to gather robust sleep data from thousands of people in 100 nations. The researchers examined how age, gender, amount of light and home country affect the amount of shut-eye people around the globe get, when they go to bed, and when they wake up. Among their findings is that cultural pressures can override natural circadian rhythms, with the effects showing up most markedly at bedtime. While morning responsibilities like work, kids and school play a role in wake-time, the researchers say they're not the only factor. Population-level trends agree with what they would expect from current knowledge of the circadian clock. "Across the board, it appears that society governs bedtime and one's internal clock governs wake time, and a later bedtime is linked to a loss of sleep," says Daniel Forger, who holds faculty positions in mathematics at the U-M College of Literature, Science, and the Arts, and in the U-M Medical School's Department of Computational Medicine and Bioinformatics. "At the same time, we found a strong wake-time effect from users' biological clocks - not just their alarm clocks. These findings help to quantify the tug-of-war between solar and social timekeeping." When Forger talks about internal or biological clocks, he's referring to circadian rhythms - fluctuations in bodily functions and behaviors that are tied to the planet's 24-hour day. These rhythms are set by a grain-of-rice-sized cluster of 20,000 neurons behind the eyes. They're regulated by the amount of light, particularly sunlight, our eyes take in. Circadian rhythms have long been thought to be the primary driver of sleep schedules, even since the advent of artificial light and 9-to-5 work schedules. The new research helps to quantify the role that society plays. Here's how Forger and colleague Olivia Walch arrived at their findings. Several years ago, they released an app called Entrain that helps travelers adjust to new time zones. It recommends custom schedules of light and darkness. To use the app, you have to plug in your typical hours of sleep and light exposure, and are given the option of submitting your information anonymously to U-M. The quality of the app's recommendations depended on the accuracy of the users' information, and the researchers say this motivated users to be particularly careful in reporting their lighting history and sleep habits. With information from thousands of people in hand, they then analysed it for patterns. Any correlations that bubbled up, they put to the test in what amounts to a circadian rhythm simulator. The simulator - a mathematical model - is based on the field's deep knowledge of how light affects the brain's suprachiasmatic nucleus (that's the cluster of neurons behind the eyes that regulates our internal clocks). With the model, the researchers could dial the sun up and down at will to see if the correlations still held in extreme conditions. "In the real world, bedtime doesn't behave how it does in our model universe," Walch says. "What the model is missing is how society affects that." The spread of national averages of sleep duration ranged from a minimum of around 7 hours, 24 minutes of sleep for residents of Singapore and Japan to a maximum of 8 hours, 12 minutes for those in the Netherlands. That's not a huge window, but the researchers say every half hour of sleep makes a big difference in terms of cognitive function and long-term health. The findings, the researchers say, point to an important lever for the sleep-deprived - a set that the Centers for Disease Control and Prevention is concerned about. A recent CDC study found that across the US, one in three adults aren't getting the recommended minimum of seven hours. Sleep deprivation, the CDC says, increases the risk of obesity, diabetes, high blood pressure, heart disease, stroke and stress. 

The U-M researchers also found that:

• Middle-aged men get the least sleep, often getting less than the recommended 7 to 8 hours.
• Women schedule more sleep than men, about 30 minutes more on average. They go to bed a bit earlier and wake up later. This is most pronounced in ages between 30 and 60.
• People who spend some time in the sunlight each day tend to go to bed earlier and get more sleep than those who spend most of their time in indoor light.
• Habits converge as we age. Sleep schedules were more similar among the older-than-55 set than those younger than 30, which could be related to a narrowing window in which older individuals can fall and stay asleep.

Sleep is more important than a lot of people realise, the researchers say. Even if you get six hours a night, you're still building up a sleep debt, says Walch, doctoral student in the mathematics department and a co-author on the paper. "It doesn't take that many days of not getting enough sleep before you're functionally drunk," she said. "Researchers have figured out that being overly tired can have that effect. And what's terrifying at the same time is that people think they're performing tasks way better than they are. Your performance drops off but your perception of your performance doesn't." Aside from the findings themselves, the researchers say the work demonstrates that mobile technology can be a reliable way to gather massive data sets at very low cost. "This is a cool triumph of citizen science," Forger said. The work is funded by the Army Research Laboratory, the Air Force Office of Scientific Research and the National Science Foundation. Source: domain-b.com

Google files patent for wearable medical device

Google has filed a patent application for a wearable medical device, able to use nanoparticles to detect and treat illnesses such as cancer.

For those wishing to protect their health and extend their lifespan, a futuristic medical device may become available in the next several years. Details of this wearable technology – known as a Nanoparticle Phoresis – have been published online by Google, via the World Intellectual Property Organisation. The patent application describes a strap, or band, mounted on the lower arm. Similar in appearance to a wristwatch, it would "automatically modify or destroy one or more targets in the blood that have an adverse health effect." This would be achieved by beaming energy into blood vessels to stimulate cells and molecules, increasing their effectiveness at fighting diseases. It could even be used on synthetic nanoparticles. Millions of these tiny objects would be introduced into the wearer's bloodstream, then activated by magnets in the wristband and directed to specific locations. In addition to its physical treatment abilities, the Nanoparticle Phoresis could generate vast amounts of data – not only helpful to the user, but also to researchers and doctors. It could accept inputs from the wearer regarding his or her health state, such as "feeling cold," "feeling tired," "pollen allergy symptoms today," "stressed," "feeling energetic," etc. According to the patent, these user inputs "may be used to complement any other physiological parameter data that the wearable device may collect and establish effective signal levels for and timing of modification of the target." Analysts forecast that wearable technology will see huge growth in the coming years, with unit sales potentially reaching into the

hundreds of millions. This new device from Google – if successfully developed – could become part of that rapidly evolving ecosystem. Initially aimed at patients who are seriously ill, this product (or its derivatives) could also be offered to mainstream consumers who aren't necessarily in bad health, but wish to monitor and improve their well-being. For those with a needle phobia, injections might be possible using high-pressure jets. Although the patent itself makes no mention of this, we can speculate that such a procedure would eventually be incorporated into a wristwatch form factor. Similar to the "hypospray" on Star Trek, these jets would ensure that the skin is not punctured. High-pressure jet injection was covered on our blog in May 2012. Looking further ahead, the prospects become even more exciting. Bill Maris – who helped form Google Calico – this month stated his belief that humans will live to be many centuries old in the future, while today's cancer treatments will seem "primitive" within just 20 years. His comments echo those of futurist and inventor Ray Kurzweil, also employed at Google and currently involved in AI research for the company. Kurzweil predicts that nanoparticles will be superseded by nanobots – small and compact enough to feature motors, sensors and other tools, allowing them to be controlled with extreme precision directly inside cells. If this idea sounds like science fiction, then consider this: a handheld smartphone today contains more processing power than a room-sized supercomputer of the 1980s. With ongoing advances in miniaturisation, together with new materials such as graphene, the future trend seems inevitable. As humans become ever more dependent on technology, our bodies will gradually begin to incorporate these and similar devices on a permanent basis. Later in the 21st century, the line between man and machine could become blurred. Source: Article
