A Helpful Device - Helios Series Green Laser Pointer
Many people still have no idea what a laser pointer is in despite of its abundant applications in entertainment and scientific fields. I don't say such words without a reason. I met a friend yesterday and told him I wanted to buy a green laser for business presentation. He was puzzled what a laser could do for presentation and I explained everything to him. Afterward, I realized that not everybody knew clearly about laser device, perhaps only professional people or laser followers were familiar with it.
A laser pointer is a small device which can emit narrow visible beam with a power source, and it used to highlight objects by illuminating them with a small bright spot. Lasers can be separated into many categories, which include green lasers, red lasers, blue violet laser pointers and so on. Now a green laser pointer has become the bellwether among all lasers by its bright shining beam, clear visibility, cheap price and high quality. Green lasers have different output powers, for example, some of them range from 1mW to 1000mW and people choose appropriate ones according to their purposes.
Generally speaking, lasers lower than 5mW are safe to use. However, people sometimes have to purchase high power ones to complete their tasks. That's because many experiment effects cannot be achieved without enough power. The problem is how to meet various requirements of numerous people with different intentions?
With a wavelength of 532nm, the output power of Helios series green laser pointer ranges from 5mW to 150mW and it almost can meet all demands from different users. Helios series green lasers lower than 50mW are very appropriate for indoor presentations. Teachers at seminars, business people and interior decorators all make use of this green laser to help them to finish difficult assignments. It is indeed a capable assistant for long distance pointing and presentations.
Helios lasers from 50mW to 100mW are mainly used for stargazing and celestial objects observation. Hard explanation and arm waving are no longer needed with a laser pointer. The green laser is so bright that you can see its beam even at days, not to speak of in the darkness. Lasers above 100mW are quite useful for people who want to carry out professional researches and burning experiments. Besides, high power laser gadgets can be used in hiking and outdoor activities. The laser beam is bright enough to scare away large wild animals and users can send out signal for help in case of emergencies.
The injuries of high power laser pointers are serious and it is important for people to take protective measures when operating the laser pointer.

Hospital Grade Green Dot Cords Ensure Ultra Safe Hospitals
ByJim Pakerr
Hospitals are a place with a lot of electronic equipment required to be used in different sections and departments. And for almost all of these machines, not just any kind of cords will do-it has to be especially safe and that's why hospital grade cords are used in such critical medical applications. The 'green dot' certification is considered to be a benchmark of safety in hospital safety standards. Earlier, medical requirements entailing the NEMA 5-20P, NEMA 6-15P etc required very bulky molded plugs. But of late, the new hospital grade cords have replaced the previous system rather efficiently.
What is the importance of a green dot?
Any cord that is used in a hospital set up is required to have a green dot prominently displayed near the plug-in end of the product. The hospital grade cord signifies that the product in question is in made in adherence with the very stringent safety standards of the Underwriter Laboratories (UL) specification. These requirements apply to various materials and constructions. To quote the UL specification, it says that "all patient care equipment must use power cords with hospital grade attachment plugs."
Hence, it becomes imperative to use these plugs in a hospital set-up to ensure enhanced safety. However, it is not very difficult to source these Hospital grade green dot cords. There are some basic features of such cords that make it easy to identify them when you go to purchase these. Firstly, the blades of the plugs are required to be prolonged and should be made of solid brass, without folding. Secondly, the product should clearly carry the green dot and should also have the words "hospital grade" engraved or etched on it. Additionally, in order to ensure grounding reliability, a strain relief device should be installed on the inside of the plug mold. This also ensures that any additional stress to the connections is prevented. Also, these products are safe to use only if they pass the stringent and ruggedized tests that are performed by the UL before it finally puts its stamp of approval.
All these standard-conformations ensure that products are suitable and safe to be used in any hospital set-up and any power-cord use in the hospitals. The green dot power cords are also reasonably priced as compared to the previous ones. RV Trailer power cords are also available with a green dot now. Additionally, the internet is the preferred source from where you can purchase these green dot cards.
