Do You Need a Class 2 or a Class II LED Driver?

You have learned that it is preferable to use the Class 2 LED driver in the LED signage and lighting applications in order to better manage and limit the potential risk of electric shock hazard in installing and operating the devices. However, many people confuse the class 2 (Numeric “2”) with the class II (Roman Numeral “II”) power supply. They are both valid standards, controlled by different organizations, but they are meant to provide different protections in different methods. Here is a brief explanation of each designation to help you distinguishing between the two.

Class 2: Class 2 power supplies are governed by UL (Underwriters Laboratories) 1310 standard. The main focus of UL-1310 is to ensure the output from each channel of the power supply cannot exceed 100 Watts (or five times output voltage if is it is lower than 20V) in any given circumstances, such as the rated working temperature, start-up or shut down process and the faulty conditions. UL-1310 is applied to oversee the Class 2 LED driver as well. If you are a US domestic LED sign or lighting application builder, you need a Class 2 LED driver, not a Class II power supply.

Class II: Class I and Class II are both specified in the EN-60950 (the European standard). The former requires a ground connection – usually done by using the 3-prong AC input, established, so the extra current generated in the fault condition can be quickly shunt to ground without damaging the property or the operator. The latter calls for a double insulation on the primary and the secondary side of the power supply if the ground connection is missing. Class II power supplies are typically used in the telecommunication industry. You can find it resides in many consumer electronics products, such as the Digital Video Recorder, network switch and wireless router.

Conclusion:

If your signage or lighting application is made up of LED related illumination technology, be sure to employ a Class 2 LED driver to power your system. A Class 2 LED driver can consist of several output channels but the maximum output power of each channel won’t exceed 100 watts. By limiting the absolute maximum output power to the UL predefined level – 100 watts, the Class 2 LED driver can reduce the chance of producing excessive out-going current, over-heating the cables and creating an electric shock hazard. Thus, it can support a safer installation and operation experience for your applications.

Nine Ideas to Help Plan My Trip to Europe

So, the stage is set for your travel plans this year. You chosen to travel to Europe because it just feels right, but you begin to panic a little because you’ve started to psych yourself out by thinking, ‘How do I plan my trip?’ After all, you’ve usually traveled domestically, and there’s a good chance that most of that was in a car for an epic road-trip. You figure if you forgot or needed something, you’d take care of it along the way or at your destination. Traveling to Europe, though, is a little different because you can’t really stop along the way over the Atlantic.

You know this is the trip you’ve been waiting for, but it can be daunting to figure out where to start. Rather than stress out too much over your travel plans, use these nine steps as a guide to help put your travel plans into perspective & keep the joy of knowing you’re going to Europe:

1. Choose A Destination – Sure, you’ve chosen Europe, but that’s a continent. You need to figure out where you’ll be visiting, so sit down & hash out a list of places you’d like to visit, the time you’d like to spend there, and how it all works on the amount of time you have for your vacation. This is a key step because you’re having to choose between places like England, France, Italy, Germany, and Spain, so take your time & don’t procrastinate.

2. Create A Budget – You’re investing money in your trip, but you don’t want to break the bank. The best way to keep your money in check is to create a budget with which to operate. This is not just for how much your trip will cost but also how much you’ll allow yourself to spend on food, souvenirs, and other spur-of-the-moment possibilities.

3. Travel Documents – You need to make sure your passport is in order, and it wouldn’t hurt to check on documentation on additional ID, prescriptions, and emergency contact information.

4. Figure Out Your Travel – If you’ve chosen to visit a particular city, you want to think of the best way to get to your lodging. Is it by train or bus? Also, since you’re flying, where will be the best airport to fly into (i.e., if going to England, Heathrow or Gatwick; if going to France, Charles de Gaulle or Paris Orly)? You also want to figure out how best to get to the places you want to check out on your trip, and this will also help you establish a home-base of sorts.

5. Make At Least One Itinerary – As you start your planning, make rough drafts of how your trip will play out with destinations, lodging, and travel. Remember that there should be drafts as in more than one. You’ll find that fine-tuning your itinerary will be vital.

6. Guidebooks – Don’t think of guidebooks as “touristy” because the purpose of them is to help tourists. Find one or two that really provide good info & use them to your advantage. “Touristy” or not, they help.

7. Too Much To Do – Since you’re making itinerary drafts, remember one key item – don’t overdo it on the activities. You’ll end up wearing yourself out which is no fun. For example, checking out France is exciting, but travel experts cite that it would be easier, depending on how much time you’re traveling, to visit a city at a time. If you’re there for a weekend, try only Paris.

8. Little Things – Start thinking about how a house-sitter or pet-sitter. You’ll also want to check on your cellphone capabilities abroad, and you certainly want to put a temporary freeze on receiving mail or ask a neighbor to pick it up for you. This also helps so that they know you’ll be out-of-town & can keep an eye out.

9. Practice Packing – In the same way you used to try on clothes for the first day of school, you want to pack what you think you need & see if it works with your luggage and your ability to actually carry your stuff around. If you’re having trouble maneuvering your luggage or you’ve packed too many things, you might want to rethink an item or two & try again.

You once thought, ‘How do I plan my trip to Europe?’ Now, with this list as a guide, your thoughts should be on more important things like having fun & making lifelong memories.

Air Conditioning Installation

What Does Air Conditioning Installation Involve?

Tired of the oppressive heat? It seems as if heat and humidity levels break new records every summer. If you’re wondering about installing a cooling system in your home, keep in mind that newer air conditioners are quieter, more powerful, and more energy efficient than older models. Air conditioning even offers added value by reducing your energy bills.

Start at the beginning

The first step towards the installation of a cooling system in your home is to determine the size of the unit you need. An undersized air conditioner will not be powerful enough to cool your home, while an air conditioner that’s too big will make the air feel clammy from too much humidity. That doesn’t sound comfortable, does it?

The capacity of an air conditioner is measured in tons. Tonnage refers to the amount of heat that the unit can remove a home in one hour. A one-ton air conditioner can expel 12,000 BTU while a three-ton system will expel 36,000 BTU. The tonnage system of measurement is based on the fact that it takes 12,000 BTU to melt a ton of ice in 24 hours. For example, a house the size of 1,600 square feet could be well served by an air conditioning system of two and a half tons. A qualified contractor will be able to help you choose the capacity of your system according to your needs.

Installation requirements

For a house that has previously never had central air conditioning, installation often requires a new circuit breaker in your electrical panel, new wiring run through your foundation, and new ductwork, plus mounting of your new unit on metal brackets or a on concrete slab. Because work this crucial must be done properly, make sure to ask for a free quote from a reputable professional rather than wasting time trying to do it yourself. You will also avoid potentially injuring yourself.

Choosing a contractor

For your cooling system to be efficient and long-lasting, installation needs to be done correctly. Don’t take any chances. Make sure your contractor is qualified to install and maintain the equipment. The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) is a non-profit national trade association of contractors, wholesalers, and manufacturers in the industry. A section of their website is dedicated to helping you find a qualified contractor. It is also a good idea to check with your provincial authority to make sure your potential contractor’s licenses, qualifications, and insurance coverage are all up to date. Lastly, you can check with the Better Business Bureau online to find out if any complaints have been filed against the contractor.

All that’s left to do is to enjoy the cooling comfort of your air conditioning all summer.

How To Open Your MS Access Form In Full Screen: Discover The 10 Key Properties Required

Once upon a time you loaded your Access database, found the starting form (screen) and navigated between other related objects. Actually, this wasn’t always the case but general Microsoft Access users certainly engaged in this approach when designing a database leaving the end-user disorientated and de-motivated in utilising the firms application.

To help streamline your application making it user-friendly and more conducive to use, real database developers took advantage of the many properties in Access which included the form’s property sheet too.

In this article, I want to cover the 10 key properties required and when synchronised together it forms a smooth start-up screen environment as the Access form loads in a full screen mode removing any tempting and unwanted elements. This approach ends up with a polished and professional look and feel too which is highlighted with some simple but optional automation using Access VBA code and an auto macro.

Design your form adding all the components in the normal manner as if the form was manually called then save your changes before changing the key properties. In addition to the standard controls for your Access form, make sure you have added a ‘Close’ command button and is coded to close the form.

Next, let’s add the 10 key properties:

  1. Auto Resize – This property is set to ‘Yes’ and will automatically shape the form as it loads.
  2. Auto Center – This property is also set to ‘Yes’ and will sit dead centre should the form not fully load in a full screen view which maybe a desired effect should developers wish to change the size of a form. This will sit comfortably with the first property mentioned.
  3. Border Style – Set this property to ideally ‘Dialog’ though it can be also set to ‘None’ since it is going to be in a full screen view. The ‘Dialog’ option just follows the rules about when a screen has the focus user can optionally control moving and sizing of a form.
  4. Control Box – Set this property to ‘No’ to switch of the ability to show the control menu for a window (i.e. top left corner icon in a window).
  5. Min Max Buttons – Also set to ‘None’ to stop users from resizing the window to either a minimized, restore or maximized state.
  6. Close Button – Set this property to ‘No’ to switch off the ‘x’ icon in a window which of course will close the form. This must only be switched off if you have an alternative way to close a form (namely the command button mentioned earlier).
  7. Pop Up – This property is set to ‘Yes’ to make sure this form has the focus and viewed on top of any other previously opened form (if applicable).
  8. Modal – This must be set to ‘Yes’ and will behave as a real dialog box so that users cannot navigate away from this form until they use an alternative way to formally close the form.
  9. Caption – This property is the title bar caption which can be anything you like to display at the top of the form. I tend to use this for database title along with some clever coding to welcome the logged in user (if applicable) or just leave it blank.
  10. Allow Datasheet, PivotTable and Chart Views – All three properties deemed to be one collection here are set to ‘No’ as you only want to show the default view as set to ‘Single Form’.

Now the simple VBA code is to be attached to the loading form’s event (On Load) by adding DoCmd.Maximize in between the sub and end sub signature which will turn your form into a full screen view showing all the clean elements of the form in its full glory.

The final and optional part is to add a macro called ‘AutoExec’ (a specially reserved macro name) that triggers itself when the database file is loaded. In this macro, you add the ‘OpenForm‘ action to call your form.

Hopefully, you have the essentials in place to which you can now add further refinement to taste. Happy ever after!

Graphene-Based Composite Nanomaterial Can Prevent the Overheating of Lithium-Ion Batteries

To perform in an efficient way, LIBs require operation conditions which are within a specific range of current density, voltage and temperature. Nevertheless, when they are subjected to abuse conditions, exothermic reactions can take place, leading to a fast increase in internal temperature and pressure. What does it mean? Well, our battery is likely to explode!

Current LIBs include external sensors to prevent overheating and overpressure but, unfortunately, temperature and pressure inside the cells can actually increase much faster than they can be detected by those external sensors. Because of that, several alternatives have been developed in order to include internal components to solve the problem. For example, ceramic coating has been proven to be an effective way to shut down the battery and improving the thermal tolerance. However, after the battery is shut down, it cannot be used again. Using solid-state electrolytes can be another option, but the overall performance of the battery is decreased due to their low ionic conductivity.

About a year ago, researchers from Stanford University published a very interesting paper where they presented a new alternative: introducing a new material internally into the electrodes. Their material consists of “conductive graphene-coated spiky nanostructured nickel particles as the conductive filler and a polymer matrix with a large thermal expansion coefficient”. The spiky particles have a high electrical conductivity at a low filler fraction and a high thermal sensitivity, whereas the graphene provides high electromechanical stability to prevent oxidation and the decomposition of the electrolyte.

According to the authors, batteries that include this new graphene-based nanocomposite can work efficiently in a wide voltage window at normal temperature, whereas they can also shut down incredibly fast when the operating conditions are off limits. The best part is that these batteries can actually be reused right after the overheating event takes place, which is a major advantage!

Basically, the previously mentioned nickel nanoparticles promote conductive percolation and, once the temperature reaches a well defined value, the whole nanocomposite becomes insulating due to the increase in volume of the polymer matrix, interrupting the conductive pathways. Then, when the temperature decreases, the matrix contracts again, thus allowing the material to recover its conductivity. In addition, it has to be highlighted that the temperature at which the material will “cut” the current is a design parameter which can be controlled by modifying the composition of the material.

I highly recommend reading this paper from the Nature journal (“Fast and reversible thermoresponsive polymer switching materials for safer batteries”) to learn more about this topic. Since my work is related to crashworthiness of vehicles, I always tend to look for connections between new technologies and its potential applications to my specific field. Therefore, in this case it is pretty obvious that this research will help to improve the safety levels of electric vehicles in the event of accidents, where the batteries are very likely to catch fire due to the energy which is released during the impact.

Water As Fuel – For Our Vehicles

Water is maybe the most important fuel mother nature requires. Isn’t it about time for us all to turn to this natural gift to fuel our vehicles? Because it can and it’s safer for us and the environment.

While we should be concerned about the rising costs for petrol and diesel, we should also be concerned with the destructive force we are creating with our Carbon Emissions from the Hydrocarbon fuels plus other emissions which is destroying our environment. With the number of cars on our roads continuing to increase globally. The emissions from our car exhausts will only continue to increase, therefore increasing the environmental pollutants in the Air.

Hydrogen mixed with the combustion process, burns the tiny flames created by the combustion process, a lot faster. This means most of the hydrocarbon fuel particles gets used up rather than escape through the exhaust system.

You see, hydrogen is the smallest known molecule known to man. When it is forced into the combustion chamber of an engine, the increased number of molecules ensures that there are more molecular collisions. As hydrogen molecules burn faster than gasoline ones, it reduces the time it takes for combustion. This results in a more complete burn sooner in the stroke which means more energy is converted into power, reducing the energy leaving the engine during the exhaust stroke. There fore giving the vehicle less dangerous emissions and more power.

So, the advantages of looking at using water as fuel for our vehicles are many. Lets look at a few.

– up to 50% reduction in fuel expenses,

– up to 60%+ more fuel economy,

– reduced hydrocarbon emissions,

– cleaner burning engines in our vehicles,

– reduced maintenance costs,

– cleaner environment,

– uses water from your tap.

You have nothing to lose. The pluses are many.

8 Basic Ways of Preventing Deforestation

There have been so many discussions on the effects of deforestation in our environment. These effects range from alarming to catastrophic. We have read newspaper headlines that show the wreckage that natural disasters have done. Flashfloods have not only damaged millions of properties all over the globe but it has also collected lives. Landslides have done the same. These two are the results of nature’s balance that has been disturbed–they are the effects of deforestation.

Deforestation is the act of converting patches of forests to become areas of residence or industry. More and more businessmen are pushing through forests to obtain more land. Environment is sacrificed in exchange for profit. And this is a highly disturbing fact.

As an individual or as a part of the global community, you can do something to help prevent deforestation. Maybe you can’t fight off illegal loggers with your bear hands but with some basic ways, you can make a difference–no matter how small. Here’s a list:

1. If deforestation is a negative event, then a positive event should take place to counter its effects–reforestation. Plant trees and begin doing this in your yard. Trees give off oxygen that is essential for human existence and they, in turn, capture the carbon dioxide that humans and animals exhale. Trees also help in containing water in its roots. With this simple act, you are able to prevent soil erosion, which is the root cause of landslides!

2. Use recycled items such as books or pad paper, toilet paper, even shopping bags. If you can, do not waste any of these products so that no new raw material would be required to replace them.

3. If you are a farmer (or if you know someone who works as a farmer), try to rotate your crops. Instead of using a different portion of land each year, why not use the same portion with different crops? This practice also helps in maintaining the fertility of the soil. With the rotation of crops, not only is there a variety on the harvest each year, there is also the possibility of keeping that portion of land for as long as you can.

4. Cut down only the mature trees. Do not kill baby trees. And for every tree that is lost, plant another one as a replacement.

5. Join environmental awareness groups that would help you be an advocate of reforestation. In Washington, specifically in the Washington Middle School, there was a group of students that established a service-learning project. In their project, they asked a penny from each person. They explained that this money would help in buying acres of the rainforest in Amazon. Once this pushes through, no deforestation could take place in that purchased area.

6. There is a report that in Indonesia and Malaysia, more and more trees are cut down to produce palm oil. This massive destruction in the forests of both countries resulted into the loss of habitat for the native orangutans. With the loss of more trees, more animals become homeless. You can’t help prevent this altogether but you can limit your consumption of products that contain palm oil such as breads, chocolates, and even some cosmetics such as shampoo, soap or toothpaste. As to your food consumption, you can begin a diet of roasted or boiled foods instead of frying them.

7. Instead of using firewood, use coals to heat up your fireplaces during the winter season. Remember that it takes only a few hours to consume the firewood but it would take years to grow a single tree. Think twice before purchasing firewood again.

8. Support the laws or programs that were made to protect the forests and to stop any form of deforestation. Programs such as the Tropical Forestry Action Plan have done a major difference on the way deforestation is looked at today. This program spearheaded the discussion of tropical deforestation.

It is imperative to know that there is no such thing as a small, insignificant act when it comes to defeating deforestation. No matter how small your deed maybe, the important thing there is ‘every act can make a difference’. Deforestation can be prevented and you can be an active force in achieving that.

Deep Throat Techniques – 7 Practical Steps To Learn How To Deep Throat

Mastering different deep throat techniques will certainly get you on your way to some sexy deep throat love. And with the instruction you can create an incredibly erotic visual and a heightened sense of pleasure on the underside of your partners shaft.

But if you’ve only ever seen images of a woman’s throat expanding and contracting as a penis bulges in and out. Then it’s only natural to be thinking, what’s really in this for me other than a strong throat constitution and avoiding the taste of semen?

Whilst it’s definitely not for all women, if you love to be in control, have a sense for adventure and already thoroughly enjoy giving head, chances are with the right techniques you might just get a kick out of performing it.

Starting out, deep throat love can appear a daunting task but if you want to learn to deep throat you must first acknowledge that it’s a process that is practiced in stages. You’re not going to achieve the results either of you desire with you closing your eyes and hoping for the best and him being over eager, thrusting away with you choking on the other end. No one wants deep throat choke, so take the time to learn the proper deep throat techniques that will make performing it a lot easier to swallow.

Stage 1 – Positioning

Your correct positioning is one of the most important techniques, especially when starting out. The best way to learn is with him lying on his back with you on your side dictating when and how far you can comfortably go. Only when you have become totally accustomed to the sensation of deep throat and can control your body’s natural reflexes, should you consider trying a more submissive position such as lying on your back with your head hanging off the back of the bed. (irrumatio)

Stage 2 – Lubrication

There will definitely be no deep throat love if your mouth and throat are totally dry. So it’s very important to acquire the right deep throat techniques to ensure your mouth is well lubricated in assisting his penis sliding in to your throat. Regular sucking can tend to dry your mouth out after a while but if you press his penis as far back in to your mouth as you possibly can and hold it there for a few seconds, the back of your throat will begin to lubricate with thick saliva. Continue to do this a few times. Suck then hold, take a breath, then suck and hold again. This is known as the deep throat suck and with persistence, gradually your mouth will become a super slippery, deep throat friendly environment.

Stage 3 – Open Wide

It goes without saying that in order to perform any sort of sexy deep throat you are going to have to open your mouth really wide, but there is even a savvy deep throat technique for this. You may have noticed during fellatio the back of your throat prevents the penis from going any further. In order to get passed this, the trick to successful deep throat is opening your mouth wide enough (like a yawn) and titling your head back far enough to allow the penis to slip into your throat. This is easier said than done and will take some practice. Essentially you will need to try to create one long straight line between your mouth and throat. If you don’t get this straight line with your head tilted back, his penis will get stuck at the back of your mouth and won’t be able to move down your throat.

Stage 4 – Prepare For The Gag Reflex

Once you have practiced the head tilt, you should now be ready to take him in your mouth. As he enters, a good technique is to flatten the back of your tongue to help the muscles in your throat open.

At this point you should also prepare for the gag reflex. Unfortunately, there is no avoiding this, so when it occurs, try to be calm, pause, and hold him there as long as possible. Gagging is uncomfortable and can take a while to get used to but if you can repeat this step as many times as you can, eventually you should be able to suppress this feeling and gradually be able to take him in further. A good trick to help with this is to also try breathing out while taking him in to help stop the gagging reflex.

Stage 5 – Persistence

When you take it upon yourself to learn to deep throat, you must be prepared to be persistent. So when you get to the point where his penis hits the beginning of your throat it will be normal to feel a little resistance. In this case, you will need to flatten your tongue to open the back of your throat and create the flat straight line again. A little push from your partner is another deep throat technique that can help, as long as you’re aware it’s coming. You can also try to pull his penis in further using your tongue as a lever, to draw it in then push it back out. With a little persistence you should be able to take his penis in deeper to the point where you can take the entire length of it over your tongue and down in to your deep, deep throat.

When you have gotten this far just remember you don’t need to hold him in your throat for too long. Good deep throat techniques include practicing comfortably bringing him in and then letting him out, giving yourself a break when you need it. Deep throat does not have to mean leaving his penis in your throat.

Stage 6 – Breathing

No one wants a deep throat choke so always remember to breathe! It may sound obvious but it’s actually very easy to get lost in the process and tighten up as a result of a large foreign object pushing into your throat. It’s important to relax and take your time and learn to maintain a normal breathing level.

Stage 7 – Practice

Perfecting these techniques will take practice and perseverance. Follow the stages slowly and at your own pace to help you progress to where you can comfortably and confidently move on to the next stage. With practice your movements will become smoother and faster.

On a final note, if you get through all the stages you will want to know if he his planning or hoping to ejaculate down your throat. Some women do not like the taste of semen and deep throating gets around this. However having a man ejaculate directly down your throat in a restrictive position may be confronting and not desirable to some women. It is not absolutely necessary for you to have to deep throat swallow so discuss your partners intentions beforehand to ensure good, mutual happy deep throating!
