Problems of Apple Users to Use AirPrint through iOS

The iOS is a new mobile operating system made by Apple Inc. and allocated mainly for Apple’s hardware. It is such an operating system, which controls a number of the iDevices of company. Originally launched in 2007 mainly for the iPhone, it is extended to hold up other Apple devices for example the iPod or iPad.

Introduction of AirPrint-

In one of the current version of the operating system of iOS, Apple has introduced a new item called AirPrint. It is made to bring an innate printing support to the platform of iOS and this can be available on version 4.2 or also in some other devices for example, the iPhone, or the iPad. There are some steps that should be followed to use this AirPrint to any type of printer that is linked to a Windows computer, comprising Windows server. With the help AirPrint, it seems simple to get full quality image and file printing from the iOS as well as OS X applications. AirPrint is prepared into most accepted printer systems. The features comprise easy discovery, mechanical media choice, and enterprise-class options.

Problems of the Users

However, though some users claimed that iOS is quite useful to them, there are some others who reported that this new operating system of Apple has caused a number of troubles in case of AirPrint, a tool that lets the iOS to print over Wi-Fi. The problem does not allow the users to print.

From the various reviews on the page of Apple’s forum, it is known from the customer that whenever they update they update their iPhone or their handsets to the operating system they found an error message, that is, URF error and consequently the printing gets halted. In the opinion of most of the users, AirPrint functions with devices that are running through iOS 7.

An online discussion with a Support representative of Apple did very little to solve the current problems of AirPrint. The Apple agent has stated that AirPrint is supposed to work well, and thus, the users must get in touch with AppleCare or they can arrange a meeting with the Apple Genius if they are facing difficulties with the wireless printing. Though, Apple has not given a satisfactory response to the request, a British-American website for news, on the other hand, quoted a statement on a discussion panel, which denotes that Apple might fix the trouble with its approaching version of iOS 8.1

However, there could be a hopeful side in this context. On one of discussion forum about Apple , it is said that the company is already aware of the faults and announced that iOS 8.1 will faults very soon.


There are also some other complaints that a number of printers, yet listed under the list of some popular models of Apple are no longer well suited with the Airprint when they update iOS 8. Some other users reported that the printer itself perhaps needs some modifications of the firmware to work properly with iOS 8.

The Outcome of Blackberry’s Plan

The device manufacturer BlackBerry decides to get closer to its potential clients while creating strengths that extend far beyond the cell phone devices into security.A part of the plan for the growth of the company is to open up the APIs in order that customers can create applications that use BES and many other BlackBerry items.

The company is moreover functioning on a set of controlled principles for communications with the devices by means of BES. It is observed that devices employed in a range of industries previously run QNX, and thus incorporation of BES as a solution would be quite simple

Opinions of John Chen

One of the facts that are the most noticeable about new CEO of BlackBerry John Chen is that he is very frank regarding some of the challenges that can be faced by his company.

In a discussion with The Financial Times, John said that there is only fifty percent chance of success about the comeback plan of BlackBerry and the whole thing depends on how he and his associates perform.

As a whole, Chen gave an optimistic attitude in the conference and elucidated the need to uphold a positive approach in the face of discouraging odds. He stated that losing the major commercial and government clients has definitely hurt confidence but he also declared that his aim was to make certain that

BlackBerry maintained the new customers it acquired by delivering better services as well as products and by concentrating on the heritage by delivering continuous mobile solutions.Chen anticipates getting BlackBerry’s finances stable by the following year and it would be always profitable for the company.

In accordance with the International Data Corporation only some companies have dropped as far and as quick as BlackBerry has. But at present the percentage is below one both domestically and internationally.

A researcher, named YouGov have noticed that the number of people who found the device favorable got gradually decreased and has become almost half since the year 2012.

Comeback plan of Blackberry-

To revive the brand of BlackBerry brand is a really a great challenge to the company. The new plan of the company is to provide a great favor in the sectors such as healthcare, administration and insurance, who want a tool.

And according to Christoph Becker is the most potent device. So far, the largest move of Blackberry has been the release of Passport, which a model pf 3.6-inch in width with a square-like display. The technology editor of Mashable, Pete Pachal regarded the device to be very strange but also appreciate it on the other hand.

The market seems to be attempting to make a development of the Passport. The company sold 200000 Passports on the very first day and hopes to deal more in case of BlackBerry 10 at a quite cheaper rate.

How to Delete Your Data From Your Android Phone Safely

There have been numerous ways through which a user can delete their data when switching between iPhones, but what about the users relying on Android phone. If you are looking to sell your phone or even to lend it to a friend, then you need to make sure that all your data is deleted from your phone. The steps might vary depending on the type and model of the Android phone and also the device manufacturer. There have been changes in the settings and name of certain menus in different models of the Android phones, but at the end the basic steps of deleting the personal data will mostly be the same.

1. Data from the MicroSD card:

The first thing that comes to our mind when changing a phone is the data available on the microSD. Usually if one inserts their SD card from the old phone to the new phone then the data like videos, photos and music should be easily migrated over. In case your latest phone doesn’t have any slot for SD card or by any reason you don’t want to carry over the card then first thing you need to do is to backup all the data and then format the card. The simple steps are:

1. Connect your phone to computer and you have necessary application available for data transfer

2. Now click on my computer and navigate through your phone and copy all the data to your computer

3. Unplug your phone and reformat the SD card.

One can even format the card on their phone by going to the settings and clicking on erase the card. However there are people who can trace your data from your card. To avoid this, one should copy some other data about the size of the SD card and delete it. This will replace the old data and your old data will be gone forever.

2. Back up data on the phone:

Apart from deleting the personal data, you might to back up your contacts and other information. Google account has been a benefit for Android users as they automatically back up your data but one can manually do this by going to the setting options and choosing back up my data. This will lead them to Google account to further back the different types of data available on your phone.

3. Deleting everything

Once the data has been back up, completely delete all the data from the phone. Carrying out a simple factory reset will ensure all the data on the phone is deleted. Users will just have to go to setting and they have the option of Factory reset.

4. Restore data to another phone

If a user has followed all the above mentioned steps then they will be able to restore their data to another device. If you have your microSD, just insert in the new phone and all your music, photos and videos will be automatically restored. If not you can just sign in you Google Account and get all your contacts and photos that were backed up.

Researchers Evaluating Powerful Batteries for Modular Grid Energy Storage

TransPower’s GridSaver, which is the largest grid energy storage system, is currently being analyzed at Sandia’s Energy Storage Test Pad, located in Albuquerque. The laboratory-based characterization of the Gridsaver has been started by the Sandia National Laboratories. According to David Rosewater, Project lead, the laboratory is currently investigating the frequency regulation of the system; they are investigating as to which grid operator will be required for the moment-to-moment difference management between demand and the electrical supply.

The data that will be generated after the characterization of a large system like that of Gridsaver will help in improving the operational performance, technology identification and gaps in the research. They will be able to provide feedbacks to the manufacturers so that they improve the performance of system, safety and reliability.

There are other tests which will help Sandia’s to validate the energy storage and their characterization protocols. This has been developed by national laboratories and industry, according to the preset standards for measurement and energy storage performance. According to Rosewater, carrying out independent evaluation will enable to the industry to receive feedbacks so that they can improve performance, standardize metrics for reporting and characterizing and safety.

Electricity, utility and transmission providers and regulators often want to ensure that their equipment is proven reliable and safe before they can be allowed to operate on the electric grid. Although they are concerned with the safety, integrators and energy storage manufacturers are time and again unable to provide the necessary logistics which can enable long term monitoring and testing of the equipments.


According to Rosewater, although the industries need these standards, they are deprived of the same. They are hoping this protocol will provide them with information will help them to compare lead-acid battery, flow battery, flywheel and lithium-ion systems. Sandia’s Energy Storage Test Pad and Energy Storage Analysis Laboratory test have been able to prove the specifications given by the manufacturers’ concerning energy storage devices through application-specific cycle testing and characterization.

These systems will help the users to evaluate the system parameters which include the performance specifications, storage device efficiency, balance and reliability of the plant operation.

According to the Rosewater, the job of the operators has become more difficult since the state, national and local policies are pushing for a cleaner and much more accurate electric grid for a significant increase in the variable renewable generation. He says that Storage will help in mitigating that variability as to when the storage is reliable, safe, cost-effective and sustainable.

According to energy storage program manager in the Department of Energy’s Office of Electricity Delivery and Energy Reliability, Imre Gyuk, development of an energy storage system required complex incorporation of many components further than just battery. This includes sophisticated power controls and electronics.

Mainly for communications. Sandia’s is focusing on assessing the complete system. Currently there are 4 challenges that have been identified by the office namely, validated reliability, the cost of energy storage technologies, safety documentation and a regulatory environment for acceptance of the industry.

Researchers Are Promoting And Increasing the Switching Contrast Of an All-Optical Flip-Flop

The switching contrast of an all optical flip-flop has been increased by 28 dB and this has been done by the researchers at the Rochester Institute of Technology based in New York. Due to this increase the resultant switching contrast; have been achieved at now 36.6 dB.

This development will be adding a lot of benefit and will allow increased performance of a whole range of the photonic techniques like for example, all-optical label addressing, all-optical packet switching, and square-wave clock generation.

Apart from these, other photonic devices like passive nonlinear media and even housing semiconductor optical amplifiers will show a leap in terms of their performance.

Speed: 

When it comes to all-optical flip-flops, they give a path for the sequential signal processing. This is completely opposite to the signal processing which is combinational in the optical domain. Devices based on the combinational processing get the added advantage of latchable control signal due to the sequential-processing nature of all-optical flip-flops.

According to Drew Maywar who is among the authors of letter, the University of Tokyo, and Eindhoven University of Technology as well as optical-packet switching which was performed at the University of Ghent made use of optical flip-flops to drive data-wavelength converters, which helped them to attain a wavelength that can help in the routing of the optical packets?

According to Drew, there are some of the optical flip-flops whose switching performance is very poor and have specific polarization states. The cycle switching time is more than 1 ns which is not ideal for many applications.

Latching: 

Nonlinear polarization rotation and optical dispersive bi-stability were the two disparate physical processes which were exploited by the team to achieve the contrast enhancement of 28 dB. This resulted in the increased switching contrast due to the bi-stable polarization rotation in combination with the linear polarizer.

According to Drew, the research team was able to develop a latchable polarization switch. One of the advantages of the enhancement was that it was able to outperform against the performance of standard method that was being used to measure contrast.

According to the previous standards in order to achieve a contrast of 5 dB, oscilloscope and photodiode were more than enough, but once the contrast technique was improved, the upper bound for the contrast was increased to 15 dB.

Miniature: 

Currently, Drew is expecting that their latest work can be extended to other forms of resonators like distributed feedback structures, rings, vertical cavities and loops. They are hoping it to be extended to nonlinear media like SiO2 and In P.

They are hoping that the new flip-flops become the building blocks for devices contributing to large functional photonic subsystems. The team will be working on making the miniatures of the all optical flip flops.

Mayway hopes that the all optical flip flops will be continuously researched on contribute to the future. They contribute to improving the performance of switch and is able to tackle drive power issues.
