Computer Calibration

  1. Although the entire process is commonly called “calibration” it is actually a two-part procedure: adjusting the monitor, which is also called “calibration”, and creating a monitor profile for the specific monitor being used. When the two steps are done correctly, the chances of coming up with accurate output increase significantly.
  2. Every monitor displays color differently. There are differences between various models when they are new, and these differences can increase as the equipment ages. When uncalibrated, even new monitors don’t display color accurately. The human eye (in conjunction with the brain) does a wonderful job of interpreting the brightest areas of the screen to look like neutral white and the darkest parts totally black. The reality is, nearly every monitor when shipped has an overall blue-ish cast because of the initial factory settings.
  3. To understand why requires a little color theory. Scientists describe colors on a color measurement scale that uses degrees Kelvin (K) as a unit of measurement. Colors are described as being of a certain “color temperature” along this scale.
  4. The white of a new monitor is generally around 9300K, because this is the default factory setting. A 9300K white is considered very blue. The color temperature of output is determined by the color temperature of the light illuminating it. For print output, viewing booths illuminate the press sheets with 6500K or 5000K light. Transparencies are viewed on 5000K color-corrected light boxes. 6500K is much less blue than 9300K, and 5000K looks downright yellow compared to 9300K! This is just one of the reasons that output will not match the monitor image on an uncalibrated monitor.
  5. Another reason is called “gamma”. This is a term used to describe the way in which brightness transitions from white to black. The lower the gamma of a device, the brighter the mid-value of gray will appear when reproduced on the device. Macintosh systems have standardized on a gamma of 1.8 while Windows has standardized on 2.2, which explains why images appear lighter on a Mac system. But the gamma that the monitor is actually reproducing may or may not be that of the system due to aging of the monitor as well as the characteristics of the video card to which it is attached. Thus the gamma of both the monitor and the video card must be correctly adjusted during calibration.
  6. With all of the variances between monitors and their tendency to drift from any set value over time, the only way to ensure that images will be consistently displayed is to periodically calibrate them. The problem is compounded in larger imaging labs where the same image may be adjusted by different technicians at different times on different monitors. Unless all of the monitors are calibrated to the same standard, each technician may adjust the image to display “accurately” on the monitor in use, degrading the color and perhaps making it impossible to output properly.
  7. The steps in calibrating a monitor include adjusting the brightness and contrast controls on the monitor itself to set or perceived values, setting a white point (color temperature), adjusting or selecting a gamma, and defining the red, green and blue phosphors settings. These adjustments are then saved as an ICC profile that now understands the characteristics of the monitor. Macintosh computers store this information as an ICC System Profile while Windows 98, Me, 2000 and Xp store it as an ICM System Profile. Windows NT does not support system-wide color profiles, but will save the information for use with ICC-compliant applications and video cards.
  8. Other than buying a “self-calibrating” monitor from Barco, the quickest way to calibrate a monitor is to use Adobe Gamma, which is automatically installed in your computer during Photoshop installation. On the Windows platform it is found by clicking Start/Settings/Control Panel and on the Macintosh in Apple/Control Panel. Double-clicking on Adobe Gamma launches the application.
  10. Adobe Gamma is a perceptual method of color adjustment, meaning that users make adjustments to contrast, brightness, gamma and color phosphors according to what they see. Using the Wizard interface is the most informative the first time through. The first screen instructs the user to set the contrast gain on the monitor to its maximum setting, and then adjust the monitor brightness until a gray square is just slightly different in value from its black surrounding.
  12. The next screen asks the user to select the phosphor set of the monitor. Film or video professionals will choose PAL, SECAM or NTSC standards from the drop-down menu, but Trinitron is the safest selection for imaging applications, unless the monitor supplier has specific values available that can be input into the Custom boxes.
  13. Gamma is set in the next screen by moving sliders under red, green and blue squares to set the existing gamma of the monitor. Then the desired gamma for the system in use is set by choosing Macintosh default, Windows default or Custom from the drop-down menu.
  14. The next screen sets the color temperature of the display. It can be measured perceptually by clicking the Measure button and selecting the most neutral-looking gray patch from a choice of three, a difficult procedure for most users. For imaging labs, it is better to select 5000K or the slightly cooler 5500K setting from the drop-down menu. The 9500K selection is best for Web developers since this will be the way most consumers will view their work on monitors unadjusted from the factory setting.
  15. On the next screen the user can choose to have the monitor display images at a different white point than set. This is useful to check how an image will display under other monitor conditions.

  16. On the final screen, name and save the profile. The file will be automatically stored in the appropriate folder in your computer. Those working in imaging labs know that there are many variations between operators in the way that they see color, even the same operator will see color differently at different times. So this or any perceptual method of color adjustment such as Apple’s Monitor control will lead inconsistent results. For more accurate, repeatable results, monitor calibration can be done with software in combination with a hardware colorimeter or spectrophotometer. Colorimeters are three-color instruments for measuring transmitted or reflected light. They are the devices most often used to calibrate and profile the monitor, though they can be used for generating printer profiles. However, their limitation to reading three colors limits their accuracy for this use. Spectrophotometers are more sophisticated instruments for reading the reflectance or transmittance of light at specified increments throughout the visible spectrum. These devices are most commonly used to create output profiles from printers but are also used for highly accurate monitor calibration and profiling. In some cases, software is available that works with a number of different hardware units; in others, the software and hardware are sold as a package and can only be used together. With both types, the user loads the calibration software, connects the hardware unit, and follows a procedure determined by the software to calibrate and profile the monitor. Color Encore for Monitors from Southwest Software (www.swsoft.com) works in conjunction with several hardware measurement devices such as the X-Rite DTP92 colorimeter to perform monitor calibration and profiling on Macintosh or Windows machines. ColorVision’s Monitor Spyder is one of the most popular monitor calibration and profiling devices that requires its own proprietary software to function. The Monitor Spyder is bundled with either PhotoCal software or the more complex OptiCal software that allows multiple monitors to be matched to a common standard. The colorimeter is available for USB interface only and is available for Mac and Windows platforms. Eye-One Monitor is part of GretagMacbeth’s family of Eye-One profiling products (www.i1color.com). This monitor calibration and profiling package is available separately or as a module in the other products. Included is the Eye-One spectrophotometer that can be used with both CRT and LCD monitors. Other companies sell complete profiling packages that not only do monitor calibration and profiling, but handle scanner and output device profiling also. Monaco Systems (www.monacosys.com) provides an extensive line of profiling products for Windows and Mac platforms that include monitor calibration and profiling. All are compatible with Monaco’s MonacoSENSOR colorimeter. The higher end packages will also support a wide range of third-party colorimeters and spectrophotometers.

    Several profiling packages that include monitor calibration and profiling are offered by Praxisoft (www.praxisoft.com), including WiziWYG Plus for Mac and Windows platforms and WiziWYG Deluxe for Macintosh computers. Both products include the WiziWYG Calibrator Monitor colorimeter or can be used with the SpectroStar Spectrocam spectrophotometer. ProveIt! from ITEC (www.color.com) can be used as a perceptual monitor profiling program or in conjunction with ColorBlind’s ProveIt! colorimeter to profile both CRT and LCD monitors on Mac and Windows systems. ColorBlind Matchbox is also available as software only, with ColorBlind’s colorimeter or with the SpectroStar Spectrocam spectrophotometer. ITEC’s high-end profiling package, ColorBlind Professional is available with ProveIt! colorimeter, SpectroStar Spectrocam spectrophotometer or X-Rite’s DTP-41 spectrophotometer. Once the monitor profile is generated by one of these programs, named and saved in the computer, one last step will ensure that the operating system (OS) will access this information. In the ColorSync Control Panel of Macintosh OS, set the profile in the Display pop-up menu. In Windows 98 and 2000, set the profile in Control Panel/Display/Settings/Advanced/Color Management. From this screen, the profile can be selected by clicking the Add button. When you select the profile and click Set As Default, it becomes available to any program that supports ICC profiles. Monitor calibration and profiling is only the first step in ensuring WYSIWYG results, but they’re important steps. They must be handled correctly for color management to have any chance of being effective in the production process.

Gone are the days of mundane compact disks and floppies, today computer memory has taken on an all-new form. Those of you who are thinking of the ordinary Universal Serial Bus are also a step behind. Custom USB is the name of the game today and much like letterheads and business cards, these too have become necessary, be it large companies or even individually run ventures. 

The advantages that this computer memory offers are several and right from the ease in transportation to high durability, everything falls in favor of such memory. The question now is why one should opt for custom USB and where should one look when hoping to find suppliers for such computer memory 

Why opt for Custom USB? 

  

The most obvious advantage of custom USB is the free advertising that it offers. Companies often print their logos on this customized memory and it does allow them to not only identify their computer memory sticks with ease but also embed the name of the company in the clients mind. Often used as free giveaways at trade shows and other such events, a custom USB makes for the ideal marketing tool in several ways. 

Right from a simple pen shaped design to even a calculator, a wristband and also a credit card; one can design a custom USB in any form that they like. Be it 3D or not, this computer memory can take on almost any shape. It gets even better since right from the metallic finish to the wooden or plastic ones; users have freedom of choice here too. Indeed with such a large variety of choice, comes a fair amount of confusion too and therefore the next question. 

How to find suppliers for such computer memory? 

 

  

As in almost all purchases today, the net offers the best options. So begin your search online for a custom USB. Since there are several manufacturers for computer memory it will suit you to work with a provider that offers a large range of products and also has an established marketing team that can offer guidance in both selecting the shape of the custom memory as well as deciding the pre loaded content that you would like to work with. 

Memory Suppliers are said to be quite an effective team when it comes to designing a custom USB. They seem to have not only the required experience in the field but also provide specialized personal solutions for each clients needs. They offer a lifetime warrantee on the products sold and even extend a lowest price guarantee to their buyers. 

Memory suppliers offer a rather large range of computer memory and right from the Secure digital card, the Compact Flash, the Smart Media, xD picture cards, the Micro SD cards to the MMC cards and much more, everything is made available on the site.Memory suppliers for the best possible deal.

Laser Treatment For Ischemic Stroke: 

  

A research company from California called PhotoThera has been conducting tests for an effective treatment of patients that have suffered a stroke. Their approach involves usage of an infrared laser that revives damaged encephalic cells. 

This treatment is still in its experimental phase and several sequences need to be conducted right after the stroke and no more than 24 hours.Most of the testing has been done on animals, yet the treatment has proved its efficiency, compared to classic methods .Result are 70% rate of success on laser tests conducted on humans opposed to 51% using classic methods. 

This graphic explains how the device actually works. According to researchers, the laser stimulates the metabolism of weakened cells in the context of a reduced blood flow by activating certain enzymes able to control the amount of energy each cell produces.This laser may be used to treat severe neural diseases, such as Parkinson’s. 

Clever Tech: Fighting Cancer Without Chemo Side Effects

Introduction: 

    –>>fighting with cancer 

 

The effects of chemotherapy in destroying cancer are well documented.However, chemotherapy carries a high risk of damaging side effects at the same time. For some patients, these side effects are so devastating they almost outweigh the benefits of treatment. Because it can kill tumour cells, chemo also tends to blitz fast-dividing cells in skin, hair, bone marrow and other parts of the body indiscriminately. 

Targetted Chemo: 

–>>Beyond chemo 

–>>chemo 

That could be about to change, thanks to what could be a crucial weapon in the war against cancer, which aims to give targeted chemo without the side effects. The new technology is called the IsoFlow Isolation Catheter, and comes from San Jose based Vascular Designs specifically set up to work on the project. Chief Executive Robert Goldman, a Silicon Valley entrepreneur who lost his sister to the disease in the late 1990s, has spent hundreds of thousands of pounds and several years developing his idea. 

How It Works: 

–>>Cancer fighting 

Essentially, the IsoFlow Isolation Catheter fits inside the patient regular blood vessel, and cuts off the blood flow to the tumour by blowing up minute balloons before and after the vessel feeding it. This starves the tumour of blood, which is then redirected via a different route. At the same time, chemotherapy can be blasted directly into the tumour, through the area blocked off by the balloons. 

The IsoFlow catheter is guided into place with a thin guide wire. Outside the body, it uses two syringes. When in place, the first syringe is inflates the small balloons inside the vein. The second syringe injects chemo drugs into the isolated area. 

The main advantage of this invention is that it allows chemotherapy to be administered in far greater doses than would otherwise be feasible. This means treatment can be more aggressive, far more accurately targeted and potentially more effective. Chemotherapy drugs can wreak havoc on the tumour without the usual devastation to the rest of the body. 

Is It Perfect? 

–>>Side effects 

No, it would be wrong to describe this as a new miracle cure for this deadly disease. It only functions with tumours which have a well defined shape and vasculature, or circulatory system. 

The device received US Food and Drugs Administration (FDA) marketing approval just last month, and has just come available to the public there with a doctor’s prescription. It is already attracting huge interest in the medical community.It is very exciting to see how technology like this is being utilised for good. Hopefully it starts being used all over the world soon.

Lennox SunSource – Cool New Energy System: 

        

A new solar powered central heating and cooling system which reduces household electricity consumption without the usual expense of traditional solar installations has been unveiled at the International Builders show in Las Vegas.The new SunSource Home Energy System from Lennox Industries harnesses solar power to reduce the energy used by a residential heat pump or air conditioner and operate other devices in the home, like lighting and electrical appliances, when the heating and cooling system is not being used. 

What is more, if the system generates more power than the home uses, it can be sent back to the utility company, potentially entitling the homeowner to money off their electricity bill.Lennox is the first heating and air-conditioning manufacturer to use solar energy for central heating, cooling and beyond. 

The SunSource Home Energy System includes: 

  1. A solar-ready, high efficiency Lennox air conditioner or heat pump.
  2. A Lennox solar subpanel.
  3. One to 15 roof mounted solar modules which harness clean, sustainable energy from the sun and use it to run the home central heating and cooling systems as well as other appliances
  4. A communications system allowing homeowners to assess each solar modules operation and energy production online, as well as other environmental benefits such as the amount of carbon offset

Conclusion: 

       

Most efficient air conditioners and heat pumps will automatically come ’solar ready’. Consumers buy these systems will have the option to integrate a solar package at installation or later on. And because the system is expandable, homeowners can start small with a couple of solar modules and add more in the future, for a total of up to 15 solar modules per outdoor unit and added energy savings. 

TATP bomb detector:

Bomb Detector TATP: 

Destroyed by a TATP bomb (Image: Dylan Martinez/PA archive/PA)—->>>>Destroyed by TATP bomb. 

A cheap artificial nose promises to make it much easier to detect the explosive triacetone triperoxide. The device could be installed in the doorways of buses, trains and airports to sound an alarm if someone carrying TATP crosses the threshold.Attention started to focus on TATP following its use in the 7 July 2005 bus and tube bombings in London, and the attacks on trains the previous year in Madrid, Spain. The explosive can be made using easily obtainable domestic chemicals and has explosive power similar to TNT. 

But TATP’s high vapour pressure at ambient temperatures makes it hard to hide, says Siegfried Waldvogel, an organic chemist at the University of Bonn, Germany. The vapour diffuses through materials such as plastic bags and into the surrounding air, but the current method for detecting it is time consuming, as air samples have to be sent to a lab for tests. 

That could be about to change. Waldvogel and his colleagues have developed a cheap detector that responds instantly to TATP in the atmosphere. At its heart are three quartz rods, each 3 millimetres long and 40 micrometres wide, which are made to vibrate by applying an alternating voltage. Any TATP in the air bonds to chemicals coating the rods, causing their resonant frequency to change. Each rod is coated with a different chemical – a phenylene dendrimer, a cyclodextrin and sodium cholate – and each changes its rod’s resonant frequency in a different way. It is the combination of three changes that reveals TATP’s presence. 

In the presence of the explosive, the quartz crystals resonant frequency changes.In tests, the device was able to discriminate between the explosive and similar gases, sensing it at levels of 1 part per million. The team say that levels of 0.1 ppm will be possible with improved engineering. They add that manufacturers in the UK and the US are interested in building their detectors, which they believe will cost less than $100 each. 

—->>>>Picture of TATP. 

Conclusion by experts: 

“There could be an enormous demand for such a device,” says explosives expert Sidney Alford of Alford technologies in Chippenham, UK. “TATP is used both as a main charge and as a detonator in terrorist bombs, so even if it is only being used to initiate another explosive, you will still be able to sense it.” 

Internet backbone breaks the 100-gigabit barrier

Jan 27th, 2010

Introduction: 

There are few facets of society that have remained untouched by the internet.Yet at its heart the internet has stagnated. As a slew of bandwidth-hungry services come on-stream, the fibre-optic backbone that forms its trunk routes are at risk of becoming overwhelmed by too much data. It’s due for an upgrade.The first inklings of what the upgrade might look like can be seen in an ultra-fast 900-kilometre fibre-optic link between Paris in France and Frankfurt in Germany installed by telecoms firm Verizon.It is a foretaste of a high-speed internet backbone with enough capacity to satisfy bandwidth-hungry applications well into the future. 

 Same fibre network, more traffic (Image: Fancy/Alamy) 

In modern age Optical fibre: 

Today, the fastest throughput on most of the global telecommunications network is 10 billion bits (gigabits) per second so sending the contents of a full DVD would keep a link tied up for around 4 seconds. It has been that way since 1996,an era when users stepped onto the information superhighway via dial-up modems and the original Netscape Navigator browser.Masses of optical fibre cables were added to the backbone during the dotcom boom a decade ago, initially producing a huge glut in capacity. Now new users and new services – social media, video downloads, streaming audio and video, file sharing and cloud computing are filling up those fibre pipes. More capacity will soon be needed, but providing it poses considerable challenges. 

In today’s fibre-optic backbone, digital 1s and 0s are represented by switching a laser beam on and off. Lasers send dozens of separate signals down each optical fibre at slightly different wavelengths, which together can convey 10 gigabits of data per second. But this techniques has its limitations: trying to raise the data rate for each wavelength won’t work, as the signals start to blur together. The problems of signal integrity are ”100 times worse at 100 gigabits than they are at 10”. 

The starting point for the new 100-gigabit technology was to ditch the off-and-on switching, and instead modulate the phase of the light waves moving them ahead or behind by a fixed increment. The simplest approach is to shift the phase by 90 degrees – one-quarter of a wavelength – to distinguish a 0 from a 1.Higher data rates require a more elaborate process, calledquadrature phase-shift keying, which has four possible shifts, +135, +45, -45 and -135 degrees, each representing a different pair of bits, 00, 01, 10 or 11. 

 Can we cope with the traffic? 

About Gigabit: 

The 100-gigabit system abandons on-off switching in favour of changing the phase of the light waves That alone isn’t enough to reach 100 gigabits. To achieve that goal requires signals with two different polarisations, which can be separated at the receiver, each carrying 50 gigabits.Even then, after passing through hundreds of kilometres of fibre, the input signal must be processed with light from an internal laser to extract a clear signal. The receivers are equipped with powerful electronic circuits, which analyse the signal and minimise noise added along the cable, says Amin. “The end points got a lot smarter and can deal with everything in between.” 

The Canadian telecoms equipment company Nortel, which built the Verizon system, has shown it can transmit signals more than 2000 kilometres in a test on an Australian network owned by Telestra. “The 2000 kilometres was a bit of heroism. For most applications we’re saying it’s more like 1000 kilometres,” says John Sitch, senior adviser on optical R&D at Nortel.There are still some problems facing the ultra-fast backbone. Noise can be a killer if 10 and 100-gigabit channels are transmitted through the same fibre at closely spaced wavelengths. And the first generation of 100-gigabit systems can only stretch half as far as today’s 10-gigabit systems before signals are lost.
