Apple’s Curved Photosensors – Smaller iPhone Cameras


Latest Apple patent discloses that the Cupertino Company would soon employ curved photosensors in creating smaller iPhone cameras which can capture improved photos. The design would aid Apple in its task of making the forthcoming smartphone much thinner.

The U.S, Patent and Trademark Office had recently published `Small form factor high-resolutions camera’ describing a cutting edge mobile camera module which utilises complex optics in delivering a much compact footprint with enhanced performance digital shooter suitable for placement in iPad and iPhone.

This exclusive arrangement offers a comparatively small ray fan spot size for all kinds of field heights at the image plane enabling a sharp low-distortion image. Apple has informed that employing curved array limits diffraction across image field, enabling smaller photosensor with equally smaller pixels. Moreover, with an axial length of two millimetres or less, the total camera package is extremely compact.

Sensor Refracts Light Through Trio Lenses


Apple has illuminated how the sensor tends to refract light through a trio of special lenses on a concave surface causing a sharp, low distortion image. The curved array limits diffraction, enables the use of smaller sensor with smaller pixels. AppleInsider has explained that to correct the diffraction as well as the visual aberration which tends to propagate within small cameras, the proposed lens system comprises of three lenses, two of which are convex or considerably convex.

A third meniscus lens or a lens with opposing convex as well as concave surfaces is placed between the first two lens components and the spherical photosensor. However the design seems to have its limitation like barrel distortion and Apple has described how it could use software in correcting the unwanted effects that tend to appear in various degrees of severity based on focal length, aperture as well as other system settings. It is not known whether Apple plans to apply its curved photosensor patent for its future iPhones since the company has relied for long on Sony’s stellar backside illuminated modules for its imaging requirements.

iPhone Thinner/Higher Battery Capacity


The patent had first been filed in 2013 and there seems to be no reason to think that Apple would be willing in replacing the Sony built imaging system already in use. Apple iPhone has been considered as having one of the best smartphone cameras all along. On the contrary, Apple has been looking for means of making the iPhone thinner with a higher battery capacity.

Credit for the patent filed goes to Xi Chen, David S. Gere and Matthew C. Waldon as its inventors. The technology could delay the unavoidable while Apple tends to cram more components in a shrinking device line-up. As in the case of every patent, there is no guarantee that this technology would show up in the near future devices though it is good to know that Apple tends to keep pushing the boundaries with its technology.

With rumours of a FaceTime camera set to make an appearance with the Apple Watch 2 this year, 2016 could probably be the year Apple may come up with one of the smallest and the highest quality cameras one has ever seen.

You can finally disable the iPhone's Default Apps

iPhone Apps

An Option for Disabling iPhone’s Default Apps


The latest versions of Apple iOS 9 enables users to delete over 30 stock apps built-in, on iPhone. It began with Stocks wherein Apple then added Maps, iBook, Watch, Health, Tips and much more. Presently there are 32 apps on the iPhone which the users are unable to erase.

Most of them seem to be necessary such as Settings, Phone and App Store while the others like Find Friends and Podcasts are seldom used by several users. For many years, user have been finding ways of deleting some of the default apps on the phone while others have accumulated them in a folder in the hope of ignoring them as much as they can.

However, there is now another option for disabling the iPhone’s default apps though it is only available to Apple developers and one may have to pay £79, together with a bit of technical confidence and a full reset of the phone. Being complicated, it recommends that Apple could eventually be ready to permit users in eliminating the default apps. Users who intend to have an easier option of removing the apps, could follow a method which enables them to do it by downloading any special software but the apps tends to return when the phone is turned off and on again,

How to Remove Default Apps


It has been revealed by Reddit user bfodder on how iPhone users who had downloaded the beta version of the new iOS 9.3 software by using a beta version of Apple’s Configurator program enabled businesses as well as school in managing the devices to get rid of stock apps. To remove the default apps one can:

  •  Sign up for the iOS beta programme to enable the download of iOS 9.3 public beta, though the full release is not yet out. A full guide is provided on signing for the beta programme including backing of the device. 
  •  Once done, then go to Settings > General > Software Update in order to download the iOS 9.3 beta 
  •  Then download Apple Configurator 2.2 beta which needs an Apple developer membership cost of £79 
  •  Users could then set up a configuration on selecting the option of `Do not allow some apps’ On entering the commands of these apps such as `com.apple.stocks’ for Stocks they can be detached from the iPhone.

System Removes Apps But Returns on Restart


This system which was introduced last year in iOS 9 tends to remove apps though they would return when the phone would restart. This is how it tends to work:

  •  Put the app you intend to delete in a folder 
  •  Press and hold on the apps till they begin jiggling as though you were to delete or move the app 
  •  Drag the app towards the edge of the folder in order to move, so that it moves the next page of the folder, but keep the app in place when the page has been moved 
  •  While holding the app, press the home button which should fly off the edge of the screen
Last year, Tim Cook, Chief executive of Apple had stated that the company had been looking for ways of allowing users to remove default apps, but some apps like Phone were linked to functions in iOS , which meant that deleting them could have resulted in problems or rendering the phone to be less capable. Though the latest iOS trick needs difficult work-around, it could be headway for the feature to be utilised more extensively

Future iPhones could feature Li-Fi, a technology 100 times faster than Wi-Fi

iPhone

Li-Fi Transfer Information at Over 100 Gigabits


Due to the researchers at universities which include St. Andrew, Cambridge, Edinburgh and Strathclyde, Li-Fi has been in development for many years which uses light emitting diodes – LEDs in order to beam information through air and the same is received by a light sensor.

In 2011, Professor of the University of Edinburgh, Harald Haas had been credited with its creation, when he had demonstrated it with a flickering light from a single LED wherein he could transmit more data than a cellular tower. While the out-dated Wi-Fi has the capability of transmitting data around 7 gigabits per second –Gbps, Li-Fi test have portrayed that it can transfer information at over 100 Gbps, with theoretical productivity of 224 Gbps.

This means that high definition films can be downloaded on device through Li-fi connection within seconds. Fitting any type of light device comprising of a humble light-bulb with a microchip can transform the same into a wireless data transmission point according to Professor’s Hass in his TED talk. Presently Li-Fi is in highly progressive stage which means that it is very unlikely to feature in the iPhone 7 that is expected to be released in September.

New Li-Fi to Overtake Wi-Fi Connection


The new Li-Fi technology is being geared up to blow the prevailing Wi-Fi connection by providing speeds of up to 1 Gbps. It tends to work by transmitting information through light rather than radio waves which means that it needs light source, like an LED light bulb together with an internet connection.

The term had been introduced initially by Professor Harald Haas and is presently being tested in Europe and is expected to be available to consumers within four years. The possibility of the technology is that it is restricted in its present form as visible light is unable to travel through walls and a device is needed to be within direct sight of a receiver, within a radius of about three meters. It also means that it could only be utilised in rooms that are lit.

According to Spectrum IEEE, devices in future would be capable of sidestepping this limit by using a tracking as well as location system which means that a user can place a laptop at a spot on a table and allow the system to locate it and create a link.

Pilot Project in Various Industries


Presently, Estonian company Velmenni is testingthe product and it has stated that it has been tested in an office as well as in an industrial space. Deepak Solanki, Chief executive had informed International Business Times that they were doing a few pilot projects in various industries wherein they could use the visible light communication – VLC technology.

Presently a smart lighting solution for industrial environment has been designed wherein the data communication is being done through light. A pilot project with a private client is also being done where setting up a Li-Fi network in order to access the internet in their office space. But the system seems unlikely to completely replace Wi-Fi and it could be utilised along with the prevailing technologies in order to provide more efficient systems.

How to Secure the Notes App on iOS 9.3

Secure

iOS Update – Features Like Night Shift


A preview of the upcoming iOS update had been announced by Apple recently. Included in the forthcoming iOS 9.3 update, Apple has been adding features like Night Shift which it states would help you to fall asleep easily in spite of staring at the screen after sunset.

Apple is attempting in helping users to get better rest at night with Night Shift which is a setting that tends to change the colours on the screen at night. Researchers are of the belief that the blue light produced by LED screens tends to stop the production of melatonin, the hormones which informs our brain to sleep. Changing from bright white and blue undertones to warmer colours is considered to be easier on the eyes enabling the body to fall asleep naturally.

Other features comprise of enabling multiple users accounts on an individual iPad, CarPlay improvements together with the ability to password protect personal musings in the Notes app can be located in the update. With the option to protect a note, probably comprising of details of bank account number, health information of perhaps a daily diary, it feels like it should have been in the Notes app from the beginning.

Secure Note in the Notes App


Though it is not so, Apple intends fixing the same. Users need to be aware that in order to lock a note they would have to be using the developer or public beta preview of iOS 9.3. One could learn more on the risks of running a beta version of an iOS on their device and where to sign if one intends to do so, by visiting the beta page of Apple. Those already on iOS 9.3 or planning to do so, the following needs to be done in order to secure a note in the Notes app:
  • At first, begin by selecting a note, if one would like to lock down using a password of Touch ID 
  • Tap on the share button towards the upper-right hand area 
  • Opt for Password Protect Note from the list of options

Presently available as Developer Preview


Should it be the first time of selecting this option, the password would be needed and a hint to the password. Observe the warning below the password unit.User would be unable to access any secured notes on non-iOS 9.3 or Mac OS S 10.11.4, also in beta devices. If one prefers to use Touch ID in addition to a password, the switch should be left in the `On’ position.

On the other hand, one could set up or change the Notes password by introducing the Setting app on the iOS device and go to Notes > Password Protection. Here you could also change the password for your Notes, if desired. Using the password set, the next time the Password Protect Note is selected from the share menu, the note would be placed behind your password and you will be able to identify which notes seem to be protected while viewing the list of notes in your account due to a lock icon seen below the title.

Presently the iOS 9.3 is made available as a developer preview which means that it is not fully completed. No information has been provided about its arrival on the iPhone or iPad, though Apple naturally releases a preview only a few months prior to the final version.

iPhone 7 to Feature Wireless Charging and Waterproof Body

iPhone

Apple’s Next iPhone – Wireless Charging


According to a report, the next iPhone of Apple would be the first to have wireless charging. A source has informed Fast Company that as support for the QI charging technology which tends to charge phones when they are placed on an inductive pad, would feature in the new model.The iPhone 7 would have a waterproof body due to the chemical coating and would do away with the headphone jack of the iPhone, as reported earlier.

If the wireless charging tends to be introduced, the iPhone 7 would be joining several Android models, inclusive of Samsung’s Galaxy S6 flagship that have the potential of charging by placing them on pads rather than being physically plugged into cables.

 It is said that the technology does not permit charging to be done over the air though it requires phone to be placed on distinct surface. The company’s first product with inbuilt inductive charging was the Apple Watch which utilises a magnetic connector that snaps onto the back of the device and recently had created a bigger magnetic charging dock based on the same design as its inductive charging puck.

New Wireless Headphones/New Handset


Inductive charging tends to work when electricity is transferred between two objects, the charging pad and the phone, for instance, through two coils such as a transmitter and a receiver. Alternating current is passed through the transmitter that tends to generate a magnetic field which in turn induces voltage in the receiver that can be utilised to power to charge a battery or a mobile device.

If Apple intends to incorporate the technology, owners of iPhone can benefit from Ikea’s wireless charging furniture range together with charging hubs in Starbucks as well as McDonalds all over the country. The option to remove the headphone jack for the purpose of creating a thinner body would ascertain to be a controversial one.

The company would probably include new wireless headphones together with new handset or a pair of headphones that tend to link to the phone through a lightning connector. The source has also mentioned that the company would incorporate noise-cancelling technology from Wolfson Microelectronics, a UK audio company that aims to eradicate background sound.

Technology Incorporated in Various Devices


Since June 2014, third parties were capable of creating lightning connector headphones, when Apple had extended its Made-for-iPhone licensing programme. The new iPhone was scheduled for release in September and signify an important moment in the history of Apple.

 It is said that the company had reportedly slashed production levels of the iPhone 6s as well as partner unit, 6s Plus by a third, due to fears of slowing demand for the `fallow year’s models, inspite of initial sales of over 13 million units in the three day of availability.

The iPhone 7 would have to have more innovative hardware changes in order to entice the legions of fan to purchase it since the developing markets tend to reach increasing levels of saturation as economy tends to shift from a purchase to an upgrade cycle.

Some of the smartphones as well as smartphone accessories have wireless charging abilities built in and this technology is being incorporated into various types of devices, appliances and much more.
