Doodle or sweeping gestures unlock your smartphones

The smartphone can be logged into with doodle or sweeping gestures using your fingers. Scientists from Rutgers University of USA have done a study for free form passwords based on gestures in the smartphones field. Gesture password which is free form allow passwords of different shapes as well as number of fingers.

These results show that serious alternatives to other login methods as well as text logins are available for smartphone and other mobile device like tablets. These free form passwords based on gesture is extremely suitable for a touchscreen as it is fast to use, difficult to guess and extremely easy to remember. Such gesture passwords can prevent others from hacking our smartphone because everybody carries the smartphone everywhere now-a-days.

This finding will be discussed at the Association for Computing Machinery’s Conference on Human Factors in Computing Systems in the month of May 2016. 91 people participated in the survey and it was a huge success for people experimenting doodling. 2 different sets of accounts were created, 1st set social network and online banking, 2nd set shopping, gaming, dating, courses and music. It was a great finding for both the sets and goes a long way in defining the right kind of life for people.

These features can be expanded to services by internet, laptop and tablet combos, key locks, swipe cards and many more issues.

Report: Apple Plans flexible OLED Displays for iPhones

Apple is developing iPhone largest till date. It features 5.8 inches screens with important OLED switches from LCD traditional displays. Truly speaking, Apple marks changes drastically from 5.5 inches existing iPhone screening sizes. These are radical departures from 4 inches standardised iPhones in year 2014.

Decision of Apple is using displays of OLED for iPhones in future. These have been in vogue and new for fewer times now. Apple expects bringing iPhones numbered 50 million with displays of OLED in availability’s first year. Sources of DigiTimes in supplying chains have revealed this. Apple shall not rest in integrations of OLED since its pipeline of innovation brings flexible and foldable OLED displays for iPhones of future. This was said by Ray Soneira of DisplayMate to MacRumors.

It pointed towards fewer patents related being filed by companies in 2015 September. With usage of displays flexibly, Apple has abilities of eliminating bezels from side of iPhones. It integrates gestures or functions useful. It is thing that Samsung does with flagship products namely Galaxy S7 Edge and S6 edge. OLED display has important benefits because it is light, thin thereby offering viewing angles.

5.8 inches iPhones of Apple shall go against directly Galaxy Note Series of Samsung. Newer iPhone SE are being launched on 15th March 2016. First iPhones with OLED displays shall be launched in 2018. I was told by The Korean Times.

HTC likely to Introduce 3D touch technology to smart-phones

3D touch technology in smart-phones has been a trend setter. While Apple has been a pioneer in this sort of 3D tactile technology, many other companies have also come to the forefront like HTC. Recently iPhone 6S has shown promise as a device with 3 D Touch technological knowhow. Google Nexus smartphone by HTC has been another major contender to Apple, such that the Touch technology has become a bit of common features.

3D Touch technology makes users interact with smartphone intuitively more with devices through screens being pressure sensitive that mimics responses and feels of realised buttons. In longer runs force sensitive technologies promise also better or new application from games lifelike more and virtual realities for adding sounds, temperatures and textures to screens also.

As per (TOI) Times of India, HTC shall be making and manufacturing Nexus next handsets. This uses 3D Touch like displaying technologies being sensitive pressure wise in smartphones of Google. There are possibilities as to that the Google may look at features makings Android standards. Addition of reports is that smartphones brand of China such as Vivo, Xiaomi, Oppo and Meizu works also on handset with these technologies.

Recently most, Gionee conducted unveilings of Elife S8 phones boasting 3D Touch features also. Supports lacking from developers of apps have hampered so far proliferation of Android device technologies.

Flexible Photovoltaic Technology: Its features, benefits and Applications

Flexible Photovoltaic Technology is technology of research levels. It was example of one that had been created at Massachusetts Institute of Technology. In this solar cells were manufactured by deposition of photovoltaic materials on substrates that are flexible like ordinary paper. There is also usage of chemical vapour deposition technologies. Manufacturing technologies of solar cell on paper had been developed by researchers group from National Science Foundation and Eni-MIT Alliance Solar Frontiers Program.

Features: Photovoltaic organic circuit materials have been deposited in 5 layers on substrates of ordinary paper in vacuum chambers. This is done by conformal coating of conductive electrode polymer with chemical oxidative vapours. Process is called chemical vapour deposition. Solar panels of this kind have capabilities of voltage production which exceeds 50 V. This in turn power appliance normally at lighting conditions. Solar cells are shown also being flexible. Conductive solar cells grids are same as inkjet photo printouts with rectangles patterned. When leads have been attached to substrates electrically, it has to be shown to electrical power appliances. “Printing” costs (as described by MIT) is claimed for being same as photo inkjet printing. The technology makes use of vapour deposition temperatures being less than 120 degrees. This becomes easy for manufacturing on ordinary papers. Panel’s current efficiency is nearly 1%. Researchers hope for improvement in near futures. Testing: Circuits were tested also by deposition of photovoltaic materials on (PET) polyethylene terephthalate substrates. PET sheets were unfolded and folded 1000 times. No over ting performance deterioration had been observed. There are photovoltaic materials common being deposited on deteriorated PET with only 1 fold. Solar cell was passed also by means of laser printing for demonstrating performance continued after exposures to temperatures somewhat high. It still retains procedural characteristics.

Benefits: In solar panels conventionally, panel’s supporting structures like brackets and glass are 2 times more costly as materials of photovoltaic being manufactured on them. Paper in turn costs 1 thousandth of glass approximately. Solar cells use printing process. This is much cheap than solar panels conventionally. Different methods also which involves coating papers along with material includes 1st paper coating with smooth materials for counter acting molecular scale’s paper rough. But in this process, photovoltaic materials are directly coated onto paper untreated.

Applications: In case solar cells achieve in turn sufficient maturity technologically, they are used as window shades and wall papers for electricity production from lighting room. They also can be manufactured on the clothing. This can be used for charging portable devices electronically such as media players and mobile phones. Solar flexible modules are used on roofs curved or on those roofs where there is no sense of installing rack mounting systems.

Disadvantages: For lasting more than 20 years outdoors being having elements exposure, solar cells are finished with front sheets of thermoplastic olefin or UV resistant fluoropolymer instead of glass being used in solar cells conventional. This is less costly comparatively. Solar cells should be sealed such that oxygen and water do not enter and destroy cells by means of oxidative degradation. Photovoltaic solar cell: Solar panels are imagined when one thinks of solar power (polycrystalline and monocrystalline). Flexible photovoltaic technology is composed not of highly silicon refined crystals. But instead it is 1 continuous material. 4 types of (TFPV) thin-film solar photovoltaic being classified by photovoltaic materials are used. TFPV principle is same as crystalline PV. Light strikes material. It excites electrons. Then flow by means of p-n junction permutation, thereby generating electricity’s that is utilized and captured.

There are amorphous silicon (aSi) solar photovoltaic cells: This was developed in seventies. It was made from silicon’s non-crystalline form.

Electric Locomotive – Technological Overview

Electric Locomotive is that locomotive which is powered in turn by electricity by means of third rail, on-board energy storages like fuel cell or battery or the overhead lines. Electric Locomotives along with on-board prime fueled movers like gas turbines or diesel engines are classified as gas turbine- or diesel- electric locomotives. Reason is that electric motor/ generator combination only serves as system of power transmission. Electricity has been used for eliminating smoke and taking benefits of high efficiency of electric motors. But electrification costs have meaning that only usually heavy used lines are electrified. Electric Locomotive is supplied with powers from ultracapacitor-mining powered locomotives or rechargeable energy storage systems or stationary sources. Designing features distinguishing of Electric Locomotive is: Electrical power types used DC or AC. Storing ways (ultracapacitors, batteries) or transmission (collecting) electrical powers. Means used for coupling traction motors to drivers (driving wheels).

Alternating current and direct current: Most important differences lie in choices of DC or AC. Early systems used DC as AC had not been understood nicely. Insulation materials for high lines of voltage are not available. The DC locomotives run typically at relative low voltages (600 volts to 3000 volts). Equipment is relatively massive therefore since involved currents are large for transmitting power sufficient. Power is supplied at intervals frequently as high current results in system losses of large transmission. AC motors have been developed. They had become predominant types. This is on long routes particularly. High voltages (10s of 1000s of volts) have been used since these allow uses of low currents. Transmission losses have been proportional to square of current, meaning 2 times current means 4 times loss. High powers are conducted over longer distances on light and cheap wires. The transformers in locomotives transform power to low voltages and high currents for motors. Same low current high voltage system is employed with locomotives of DC. There are no easy ways of doing current/voltage transformation for DC. This is efficient as got by AC transformers.

Transmission of power: Electrical circuits need 2 connections or 3 connections for 3 phase AC. From beginning, tracks are used for 1 circuit side. Unlike railroads model track supplies normally 1 side only. Other circuit side is separately provided. Original electrification of Baltimore and Ohio Railroad uses sliding shoe in overhead channels. This system found quickly being unsatisfactory. This was by third rail replaced. In this, “shoe” (pickup) rode on top or underneath of small rail paralleled to main tracks on top of ground level is there. Multiple pickups are there on 2 sides of locomotives for break accommodation in third rail. This is needed by trackwork. System is thereby preferred in the subway since it affords close clearances. Railways prefer overhead lines called often “catenaries” after support system is used for holding wires paralleled to ground. 3 collection ways are possible: Bow collector: It is frame which holds long collecting rods against wires. Pantograph: It is hinged frame which holds collecting shoe against wires in fixed geometries. Trolley Pole: It is flexible long pole that engages line with shoe or wheel. Driving wheels: During developments initially of electrical railroad propulsion, plenty of drive systems had been devised for coupling output of traction motors to wheels. Locomotive early often used jackshaft drives. In arrangement like this, traction motors are mounted inside locomotive body and drives jackshaft by means of gear’s set. System had been employed since 1st traction motors are too heavy and large for direct mountings on axles. Plenty of mechanical parts are involved. Frequent maintenance is necessary. Jackshaft drives are abandoned for all. But small units when light and small motors were developed.
