It has just been 50 years since the first laser has been introduced to the world, by a legend Theodore Maimam in 1960. This first laser named as ruby laser was using a synthetic ruby as grain medium and has shaken the entire world and gave a new definition and understanding in us about the technologies. Since then there are many evolutions that came in laser improvements and with ever new inventions it has been intervening in military, industrial, cosmetic, research, medicine and many other sectors changing our lives. Today they have become the integral part of human life as they are used in sensors and many electronic devices which we use on a daily basis. Apart from the existing benefits and use cases that are in light from a laser, there are many companies as well as laboratories striving to find new possibilities and new applications of the laser that would facilitate the necessities we have in our lives. Few companies have been working towards creating weapons with this technology which might lead to war.
Whats New in a 2013 Laser World?
Every year there is a new application introduced to the public with the best example being the latest 100-INC laser TV that has been provided by LG Electronics in 2013. Than to call it TV it would be apt to call it as a projector that gives access to stream internet services from this big sized screen thus giving a feel of having own theatre at home.
The new set of applications is waiting to serve us using the new technology that has been worked out by Imran Mahboob who created laser with the use of sound waves than using the regular light waves. Though it might take several years for the applications to start working surely it is the new milestone achieved in the laser evolution process.
Another achievement is at Hasso Plattner Institute where researchers have found a way to make 3-D objects with the use of 2-D laser cutters. Something called as LaserOrigami has proved to be faster than the traditional 3-D fabrication applied on 3-D prototypes by simple bending.
Swedish researchers were able to release a promising robot, at the AASS Research Centre located at Orebro University, by name Gasbot that would work continuously. With the inbuilt system made of gas sensor, GPS and powerful lasers, it would be able to collect the data and then build the maps that should give the directions to do the investigation of the places that are likely to have leaking harmful methane which then will be passed on to the workers for further process.
If someone has to experience hallucination without using drugs then it could be possible very soon with the kind of laser Forest application invented by marshmallow Laser Feast from UK. You would admire whispering trees and enjoy listening to the great music that comes out from each tree in the forest, which typically is just a rod installed in the floor.
From the science fiction there came an idea where the military airplanes can shoot the rockets by themselves which might become true in 2014 with the testing of solid self defense laser system that is installed in combat airplanes. This invention is from the USAF and it will get into real firing tests.
Lasers can even manipulate climate by formatting clouds and provoking rain, creating seed clouds, smog as well as prevents floods etc. which will all help the world. Even the common man who is finding difficulty in organizing events can go ahead once they are let to use this for their necessities. All this can be achieved from pulses of light due to which ice can be formed or water can be condensed and so on. Professors like Dr Kasparian and Professor Wolf strongly believe that laser technology would definitely help control the weather.
Professor Gerald Buller was able to find a solution to get 3-D information when a low power laser beam is passed over the object and the result of this innovation is the stunning camera that can take 3-D photos up to 1 kilometer away. The superconducting nanowires would count the distance of one laser pulse that would return back from the object and this is where it has become quite famous and expected to work well underwater or air, like in airplanes, for scanning forest vegetation, for measuring the dimensions of oceans or lakes.
The next innovation that would come into light very fast in the market provided FDA approves is the laser that would help treat the sun damage which will eliminate the need of visiting a medical institution for healing any of the damages caused by the sun. They are so genuine that even would doctors would prescribe them.
With the numerous innovations that are coming up with laser technology it becomes truly difficult to undercover all of them or would take lots of time for a common man to go through the number of possibilities and features that this laser would give us.
Wireless TV is fast becoming an issue of debate. Many consider the technology as groundbreaking, many see it as a chance to get away from the monopoly of the cable networks while others simply see it as just another high-tech thing that is drowning the modern world. Imagine no need for wires and cables and anywhere in the house the TV can access basically any channel.
For those who cannot seem to understand the concept of wireless TV, liken it to the old style communication system. In the past, in order to get a phone call, you needed a landline which depends on the transmitters. When technology modernized communication, there was the cordless telephone which used an antenna to receive the signal. Then the mobile phone came into being no need for cables, but there were still antennae. Then the latest technology improved it, no visible antenna.
This is the same with wireless TV. The old style was the antenna outside the home, usually installed at the apex of the roof of the house, and then there were the cables. But then computer technology intervened and the internet came into being. In the past the PCs needed to be hooked up to the cable or Ethernet to receive the signals until eventually there was no need of the cables, WiFi was invented. The WiFi just needed a transmitter and a receiver (the modern antenna) and the internet was accessible from anywhere and everywhere by anyone.
The wireless TV also has its own WiFi the transmitters. Using WiFi technology, the modern flat TVs can now access the internet but are controlled by the PC hooked up to it. The Internet TV on the other hand did not depend on the PC any longer; the remote could put up the control menu so the internet can be accessed separately from the PC.
Unfortunately it is expensive to have. One would need a flat TV, but if none then one would need to get the router, which can be expensive. But the router would not work without the internet server. Also, the connection is slower and if the transmitter gets obstructed, the receiver will receive interrupted signal as well, so the viewing can be interrupted.
This is new technology so obviously its maturation would take some time. However, people are positive about its future and it wont be long before this would become a standard as well.
Wireless connections are much demanded these day, be it in television, phone or internet, wireless connection rocks! What are you waiting for? Just grab the opportunity to use digitenne recorder along with kpn digitenne.
After working for years in the frozen dough industry, supplying frozen products to bakeries, cafes and restaurants, I had the chance and the pleasure to get quite a lot of experience in the production of good quality frozen dough. A good quality frozen dough product is a product which, after having been frozen for up to 6 months, still comes out of the oven as beautiful, appetising, attractive to the eyes and tasty as a fresh product. So it gives me a great pleasure to share with you some of the secrets about frozen dough production.
First don’t get mixed up with “Retarded Dough System” and “Frozen Dough Technology”. Those are two different ways of processing the dough, the first one is very simple and the second one is very much more elaborate.
– The Retarded Dough System is just normal dough that we place in a normal freezer, to be used up at a later time, may be 1, 2, or 3 days later. This dough loses some of its performance capability during the freezing process and cannot be kept frozen for more than a few days only. This is just a convenient process that we can use in some short term situations.
– The Frozen Dough Technology on the other hand is a very detailed and specific way of processing the dough, that enable the user to get the optimum performance out of the dough which has been frozen for a longer period of time. This period of time could be from just a few weeks to a few months; 6 months being regarded as a maximum for a live dough containing yeast. This is exactly what this article is all about.
First, how many kinds of frozen dough processes can we differentiate?
1) Ready to Prove Frozen Dough, good for most yeast dough and puff pastry as well.
2) Ready to Bake Frozen Dough, recommended especially for croissant and Danish pastry items.
3) Part Baked Frozen Dough, good for bread items, not recommended for croissant, Danish pastry items, and sweet bread and bun items.
4) Full Baked Frozen Dough, good for sweet bread/bun and soft roll, not recommended for bread, croissant, Danish pastry and puff pastry items.
5) Raw Frozen Dough Ready to Bake (Proving in the oven), not available yet, new technology still under intense research and development.
Critical points to succeed in frozen dough preparation
1) Make sure that the fermentation process does not start at any stage during the production.
To achieve that: one must control the temperature of the dough during all the different stages of the process, from the very beginning (mixing) to the very end (proving baking).
Ideally dough temperature must not exceed 16C (61F) during the mixing, dividing and filling of the products.
After the blast freezing procedure the ideal storage temperature is from -18C (64F) TO -22C (72F).
2) To keep the dough temperature under 16C (61F), at all time during processing, is the most difficult part and to achieve this goal we need to:
a) Keep the room temperature at between 16C (61F) and 20C (68F).
b) Use cold flour. Before use, the flour should be stored in a chiller (+4C) (39F).
c) Use cold water from a chiller or a water cooler.
d) Replace 25% of the liquid used (water/milk) with ice flakes. Or if ice flakes are not available the use of icy cold water (+2C) (35F) is recommended.
e) Work the dough straight away from the mixer without or with as little rest as possible between the different stages.
f) Freeze the dough, after shaping and filling, as fast as possible and this is when we need a blast freezer to freeze the product very fast up to the core. Why do we need to freeze the dough as fast as possible? The answer is: To bring the temperature deep inside the products to around -8C (17F) to -15C (5F) very fast, around 10 to 30 minutes, depending of the size of the products. This way the ice crystals formed during the freezing process are very small and do not damage the dough structure. If the freezing process is too long (from 3 to 6 hours with a conventional freezer) the crystals formed inside the dough are very big and will damage the yeast and the gluten structure. Then in this case the product will be very long to prove and will not rise to its maximum desired size, this is typically a low quality frozen dough.
Now looking at each kind of frozen dough processes one by one, we can say that for bread items the part baked system is the best and gives very good results. For croissant and Danish pastry items (as well as bread items) the ready to bake system gives outstanding results, but demands strict supervision, good equipment and premise.
Regarding the ingredients used in the production of frozen dough, they are almost the same as for the normal type of dough except two slight differences.
First, the yeast. Instant yeast and fresh yeast are both good to use but we always have better results with fresh yeast, products are faster to prove with more oven spring as well. Also when it comes to the quantity of yeast used, we have to increase it quite a lot (up to 2 to 3 times the normal quantity) to compensate of the yeast dying during the freezing process.
Second, the dough/bread improver used should be a special kind of improver for frozen dough only. There are many brands available on the market.
Hopefully this article has given you some useful things to think about before you start mixing the dough and I really hope you enjoyed this introduction to the process of frozen production.
While there is very little doubters indicating technology in movies is a
cancerous plague of sorts. However, with this added and very significant
plug-in, has this technological assistant gone too far?
Asset yes, but as with any good recipe that tastes like heaven, a little goes
a lot farther than a lot! Indeed, movie making in general has adopted this
formula for sometime now, but never as much as recently.
Wildly entertaining from animation, action, to supernatural movies, the normalcy
of having major amounts of technology from born via computers has quite simply,
superseded traditional production formats.
However, what happens when technology is totally taken out of the proverbial
equation as with movies of the past? You get a very plain but heavily reliant
film on personalities that drive the movie along it’s merry path.
While, these are extremely realistic flicks, they lack that little punch that
technology can add. Did you notice that ‘little’ was added in the previous
sentence? Sure you did, because that is many times, all that is needed!
For movies that can be readily expressed with this barebones strategy, the
films of today are injected with simply too much computerized technology that
waters down and sort of insults the viewer altogether.
Hopefully, this article will not be interpreted as one melancholy author who
longs for the olden days of pure movies devoid of technological advances.
While some of this may be true, it is the current state of overabundance that
technology breaches in movies today.
Unfortunately, this trend will probably be masking even more movies in the
future that would otherwise do quite well without it’s presence. Nonetheless,
technology and movies is here to stay; but scaling back will help more rather
than hurt in a vast amount of future plots on the production block!

The fast pace of modern technology means there is always a new gadget or device on the marine electronics market. For example, Lowrance recently introduced Broadband Sounder technology into their line of fishfinders. The Lowrance Broadband Sounder can actually see through structures to detect fish and is also capable of operating at high speed in deep water.
Lowrance has a strong reputation for reliable fishfinders and this new technology makes their product line more appealing than ever. The Lowrance Broadband Sounder offers increased capability for target separation and improved detail in shallow waters.
What Makes the Lowrance Broadband Sounder different?
Lowrance fishfinders with Lowrance Broadband Sounder use a 200 kHz single frequency transducer covering a 60p field of view. The transducer then sends out another signal at 83 KHz covering a 120p field of view. Because the scanning area is broader, targets remain in view for a longer period which means more information can be collected on the target, thus refining the details.
Using the Broadband Sounder technology Lowrance has overcome a common tradeoff. Typically a strong detail at the bottom has meant less definition in the shallow part of the cone. The new technology means greater definition of countours, thermoclines and underwater structures. The result is the ability to use the Lowrance fishfinder to locate fish hiding in grass, weeds, skirting rocks and otherwise playing hard to get.
When you crank up the power on a traditional transducer to increase detail in deeper waters, the result is often increased clutter. While there is more information it is often harder to decipher because of this increased clutter. The Lowrance Broadband Sounder reduces the clutter so when you turn up the gain on the fishfinder, the clutter is filtered, making the detail easier to understand and the fish easier to see. The technology is therefore really useful for clarity in deep water and at the bottom of a river, lake or seabed.
Advantages of The Lowrance Broadband Sounder Fishfinder
The new technology offered in Lowrance fishfinders provides strong bottom lock at high speeds in deep waters. It offers better clarity than previously possible in fishfinder technology and uses digital filtering algorithms to reduce clutter at high gain. This is heavy duty technology for serious fishermen. If you want to take your sportfishing to the next level, it could well be worth your while to look into the the Lowrance Broadband Sounder technology next time you are in the market for a fishfinder.
