Infrared thermal imaging equipment?

March 31, 2010 - 9:17 am 2 Comments

there is a program in discovery channel "Animal Camera - Surveillance on Survival" that shows night life of animals. It uses ‘Infrared thermal imaging equipment’ technology. I have seen others night vision that uses infra red or thermal imaging but what they show in this program the picture are show clear even u can see shadow of animals in total dark , its just like black & white picture taken in day.
are these picture are edited to see a clear picture or its just b’coz of this new technology,
can one get these camera if yes where and what are they called??

Thermal imaging isn’t new technology. Are you sure they are using thermal imaging. If you can see shadows, then they are using near IR with a near IR illumination source. Thermal imaging picks up the heat signature and doesn’t use an illumination source, thus no shadows. Also, thermal IR has poor resolution due to the long wavelengths used (generally around 5 um). Another thing that makes me think this is near IR is the grey scale. Thermal IR cameras like to make use of colors to delineate the temperature.

You can get thermal imaging cameras if you don’t mind paying $5,000 for a junky system. If you don’t mind paying $30,000, you can get a pretty nice system. Near IR cameras are cheap, but can quickly escalate in price if you want quality.

Is this right? Material to go against alarmist from a skeptic!?

1. There is no scientifically valid mechanism for CO2 causing global warming.
Carbon dioxide absorbs all radiation available to it in about ten meters. More CO2 only shortens the distance, which is not an increase in temperature. In other words, the first 20% of the CO2 in the air does most of what CO2 does, and it doesn’t do much. (Heinz Hug)
2. Oceans regulate the amount of CO2 in the air through absorption equilibrium.
Equilibrium is rapid and total as indicated by many sources of evidence. One, the graph for CO2 in the air is an extremely precise line. If nothing were regulating, it would vary wildly. Two, if equilibrium were not established, oceans would be absorbing or losing CO2 at a high rate, yet no significant change occurs.

3. Water vapor would swamp any effects by CO2, if greenhouse gasses were really creating global warming.
Water vapor has three times as much bandwidth for absorption peaks, and there are about 33 times as many water vapor molecules in the atmosphere as CO2 molecules, which means 100 times as much of a supposed greenhouse effect. And water vaporizes and precipitates so rapidly that it would be creating billions of times as much change in temperature as CO2, if the same logic were applied to it. Water Vapor

4. The public is being misled through propaganda to assume CO2 is like a sheet of plastic holding in heat.
CO2 can only absorb 8% of radiation frequencies available (No one disputes this.), and only about 1% of the heat leaves the earth as radiation—the other 99% being conduction, convection and evaporation. NASA says its 41%, not 1%, but there is no agreement, and Night Vision Equipment shows there is very little infrared radiation given off by normal temperature matter.

5. The IPCC is a bunch of political hacks who railroad the process.
It’s not what science consists of. They start at the end point which they want and then try to rationalize it through computer models which override the real science and evidence.

There is a shortage of carbon dioxide in the atmosphere for plant growth, because alkaline oceans absorb it and only release a small amount. The atmosphere is only 0.04% CO2.

When an ice age begins, global Warming occurs exactly as it is doing now. Heated oceans cause increased evaporation followed by precipitation. Eventually, increased snowfall will reflect away solar energy and trigger a cool-down.

The sun’s energy goes through the atmosphere and strikes the earth’s surface.

claimed heat due to atmosphere — 33°C

95-99% due to various things — 31.4°C

1-5% due to infrared radiation from earth’s surface — 1.65°C

8% of infrared bandwidth available to CO2 — 0.13°C

3% of CO2 produced by humans — 0.0039°C

5% of absorption "unsaturated" for global warming — 0.0002°C

claimed global warming — 0.6°C

Explanations — Crunching the Numbers

It’s actually 220×10-12 °C

This means carbon dioxide cannot trap radiant energy near the surface of the earth. To get around this, an obfuscated mechanism is contrived for heat leaving the atmosphere. But it is a miniscule effect in the stratosphere, with little influence over the lower atmosphere.

I’m not even sure my self but it seems pretty right to me

Let me add to this comment as one questioner seemed offended by it and the answer also relates to the current question. A narrowly focused education that does not interact with other disciplines to give a more balanced view of global and system processes can and will lead to judgement errors that produce inaccurate conclusions such as AGW. So it is several factors interacting that the climatologists are only seeing an after the fact side effect and blaming what they see on this minor item while missing completely the major causal effect of the sun.

Because all the major warming of the last 200 years took place before 1940 and the Co2 increase took place after 1940 as the world was dropping off into the cool period that lasted from the mid 40s through the late 70s with a short heat spike in the early 60s all with higher Co2 levels just as historical and core data shows. Co2 always follows warm periods and is not a cause of the heating but a side effect of the heating. As long as the AGW faithful continue to reject real science in favor of a religious voodoo science then skeptics will continue to be puzzled and amused by the strange responses given that do not hold up to even light scrutiny of people with broad based education’s in real life disciplines.

Global warming is a con game for economic and political power by a group of politicians around the world. It has not happened, will not happen and cannot happen and anybody with even an average high school education should know better or our schools are in worse shape than I thought they were. The sea level rise happened 11,000 years ago when the ice age ended and the mile high glaciers melted. Global warming or climate change as they now call it is on about the same level of truth as the Nigerian email scam or those emails supposedly from your bank wanting you to reenter your security information so they can clean you out. So be careful if you accept the AGW scam you are prime meat for any of the rash of identity theft email scams out there.

Eight Ways to Make Your Business Stronger in Tough Times: What to Do When Business Gets Slow

March 17, 2010 - 10:36 am No Comments

By Dan Beaulieu

 

Now that Wall Street has delivered us an economic version of 9/11, what will this mean to your business?  Will the mess on Wall Street hurt us the way 9/11 did, when some markets dropped almost  30%?   If this happens again will your industry collapse and die? 

 

Of course not.  Yes, it could slow things down for a while.  Your industry may endure a vigorous session of Pac man — but in the words of Gloria Gaynor – I/it/we will survive.  But you can do more than just survive in hard times. You can use them to your advantage.

 

I saw a piece on television the other night that said when things are down, good companies move forward.   Competent companies find ways to grab more of the market share.  I firmly believe this is true.  Those who strive to get better when times are hard, get better.  

 

Here are eight ways to make this happen for your company:

 

1.       Fire up your sales effort.  We’ve seen it time and time again, when times get tough advertising budgets are slashed, travel is postponed and sales people are laid off.  What a great time to hit the road and visit the customers of those companies.  Show strength by talking about a positive future for their company, customers and potential customers.  You will find that they’ll prefer to do business with your company, rather than those that are cutting back.   

2.       Capitalize on your company’s strength.  If your company is doing well, then use that to your advantage. If you’ve been successful enough to not worry about your line of credit, now is the time to point that out.  Let your customers know you are financially strong.

3.       Build your team. I still cannot figure out how companies can justify letting good sales people go when they are worried about business.  But they do, so take advantage of it.  Make your company stronger and snap up the good sales and operations people now available.

4.       Buy some equipment. During times like these your vendors tend to get worried.  Equipment vendors in particular can be hurt by a shaky economy.  Consequently, they will be ready to make some great deals. There is never a better time to buy equipment than in a down economy.  The discounts will fly and payment plans will be favorable.   

5.       Cut new deals on consumables. The more Wall Street scares the populace, the more companies you do business with will want to make deals.  There’s never a better time to re-negotiate that raw materials contract, then during a down economy.  Actually it’s good for vendors as well.  At least it’s better than the alternative, which is not selling anything at all.  So work with them for your mutual benefit.

6.       This is also a good time to cut deals with customers.  Now is the time to win new business away from the other guy and offer strategic pricing to win over that customer you’ve been after for so long.   But first, make sure you do this with companies that have the kind of business you want and that will help your company.

7.       Develop a new marketing plan.  Craft a strong, positive message about your fiscal strength and vision for the future.  This kind of message stands out in a sea of despair.  It will also help position your company as the one that’s doing well while others are faltering.   This will help attract new business, because you will represent the company that’s going to be around for a while.

8.       And finally show great confidence (not cockiness) in everything that you do.  You want people to know that you are in this race for the long haul and they can count on you.  And let’s face it, it’s not that much of a risk to be confident, because if you have done everything right you have everything to be confident about.

What’s interesting about so many of the industries that took a pounding during the post 9/11 economic decline, is almost all of them have come back.  Just a few years later they’re doing much better than they were before 9/11.  In fact some markets grew because of 9/11!

Remember, markets cannot be measured in days, weeks or months, they need to be measured in years.  If history repeats itself — which it usually does — then the next few years will also show strong growth.

So tomorrow morning get to work, make it happen and view the future with clear eyed optimism and confidence.  You and your company will be just fine.

Do gun owners believe their guns will protect them against a tyrannical US Government?

March 10, 2010 - 2:02 pm 24 Comments

Suppose we woke up tomorrow and found ourselves under an oppressive totalitarian government. Do you think your handguns, shotguns, hunting rifles, etc. will protect you? Keep in mind our professional soldiers have Night Vision Equipment, armored vehicles, airstrike capability, etc.

Some of you claim that gun rights were protected in order for citizens to fight against an oppressive government, but in the 1780’s, it was feasible for a group of farmers with squirrel rifles to defend themselves against a group of part-time soldiers who were also armed with squirrel rifles. These days, we have a standing army of trained soldiers who have weapons far beyond anything citizens can own. In this situation, owning a gun doesn’t make you safe, it makes you a target. Look what happened in Waco and at Ruby Ridge.
Wrath of Kahl, how many people will you take with you when you get hit by a laser-guided JDAM? My point is, there is no real way to defend ourselves against a tyrannical government, but feel free to keep living the fantasy.
sophie, thanks for having the guts to call me a Commie in public. I am so sick of people who are so cowardly they can only call me a Commie in a PM!
simon p, interesting response! The two groups of people I most love to torment are creationists and gun nuts. Coincidence?
bmovies60, nice try, but the VC had Soviet-supplied SAM’s, armored vehicles, etc. Also, the Afghanistan resistance was supplied with weapons such as shoulder-launched Stinger missiles by Ronald Reagan. Those efforts were successful, but they were helped by major superpowers. Who will help us stop Obama from sending us to FEMA camps?
Charles, I’m not saying people shouldn’t have the right to own guns. I’m just saying that if you own a gun because you think it will protect you from the NWO, you are sadly mistaken.
pacl, I was originally going to ask if gun owners thought "Red Dawn" was real, but I did not want to insult anyone’s intelligence. Thank you for doing it for me. By the way, you are right when you say that my theoretical government would have to completely get rid of the US constitution. My entire premise is ridiculous, thanks for noticing.

i know! it would be pointless. im going to shoot my .223 at your aegis destroyer

Does the fact that there were no attempted terrorist attacks while Bush was President make Obama like bad?

March 3, 2010 - 3:56 pm 4 Comments

With the exception of 9/11 because that was an actual terrorist attack and I guess you can’t count these:
Richard Reid, December 2001. A British citizen and self-professed follower of Osama bin Laden, Reid hid explosives inside his shoes before boarding a flight from Paris to Miami and attempted to light the fuse with a match. If detonated, the explosives would have damaged the plane. Reid was caught in the act and apprehended on board the plane by the flight attendants and passengers. FBI officials took Reid into custody after the plane made an emergency landing at Boston’s Logan International Airport.

In 2003, Reid was found guilty on charges of terrorism, and a U.S. federal court sentenced him to life imprisonment.

Jose Padilla, May 2002. U.S. officials arrested Padilla in May 2002 at O’Hare Airport in Chicago as he returned to the United States from Pakistan. He was initially charging as an enemy combatant and for planning to use a "dirty bomb" (an explosive laced with radioactive material) in an attack against America.[5] Prior to his conviction, Padilla brought a case against the federal government claiming that he had been denied the right of habeas corpus (the right of an individual to petition against unlawful imprisonment). In a 5-4 decision, the U.S. Supreme Court found that the case against him had been filed improperly.In 2005, the government indicted Padilla for conspiring with Islamic terrorist groups.

In August 2007, Padilla was found guilty by a civilian jury after a three-month trial. He was later sentenced by the U.S. District Court for the Southern District of Florida to 17 years and four months in prison.

Lackawanna Six, September 2002. When the FBI arrested Sahim Alwan, Yahya Goba, Yasein Taher, Faysal Galab, Shafal Mosed, and Mukhtar al-Bakri, the press dubbed them the "Lackawanna Six," the "Buffalo Six," or the "Buffalo Cell." Five of the six had been born and raised in Lackawanna, New York. These six American citizens of Yemeni descent were arrested for conspiring with terrorist groups. They had stated that they were going to Pakistan to attend a religious training camp, but instead attended an al-Qaeda jihadist camp.

All six pleaded guilty in 2003 to providing support to al-Qaeda. Goba and al-Bakri were sentenced to 10 years in prison, Taher and Mosed to eight years, Alwan to seven and a half years, and Galab to seven years.

Iyman Faris, May 2003. Faris is a naturalized U.S. citizen originally from Kashmir and lived in Columbus, Ohio. He was arrested for conspiring to use blowtorches to collapse the Brooklyn Bridge. The New York City Police Department learned of the plot and increased police surveillance around the bridge. Faced with the additional security, Faris and his superiors decided to cancel the attack.

Faris pleaded guilty to conspiracy and providing material support to al-Qaeda and was later sentenced in federal district court to 20 years, the maximum allowed under his plea agreement.

Virginia Jihad Network, June 2003. In Alexandria, Virginia, 11 men were arrested for weapons counts and for violating the Neutrality Acts, which prohibit U.S. citizens and residents from attacking countries with which the United States is at peace. Four of the 11 men pleaded guilty. Upon further investigation, the remaining seven were indicated on additional charges of conspiring to support terrorist organizations. They were found to have connections with al-Qaeda, the Taliban, and Lashkar-i-Taiba, a terrorist organization that targets the Indian government. The authorities stated that the Virginia men had used paintball games to train and prepare for battle. The group had also acquired surveillance and Night Vision Equipment and wireless video cameras.

Ali al-Timimi, the spiritual leader of the group, was found guilty of soliciting individuals to assault the United States and sentenced to life in prison. Ali Asad Chandia received 15 years for supporting Lashkar-i-Taiba, but maintains his innocence. Randoll Todd Royer, Ibrahim al-Hamdi, Yong Ki Kwon, Khwaja Mahmood Hasan, Muhammed Aatique, and Donald T. Surratt pleaded guilty and were sentenced to prison terms. Masoud Khan, Seifullah Chapman, and Hammad Adur-Raheem were found guilty at trial and later sentenced.

Dhiren Barot, August 2004. Members of a terrorist cell led by Dhiren Barot were arrested for plotting to attack the New York Stock Exchange and other financial institutions in New York, Washington, and Newark, New Jersey. They were later accused of planning attacks in England. The plots included a "memorable black day of terror" that would have included detonating a dirty bomb. A July 2004 police raid on Barot’s house in Pakistan discovered a number of incriminating files on a laptop computer, including instructions for building car bombs.

Dhiren Barot pleaded guilty and was convicted in the United Kingdom for conspiracy to to commit mass murder and sentenced to 40 years. However, in May 2007, his se
James Elshafay and Shahawar Matin Siraj, August 2004. James Elshafay and Shahawar Matin Siraj were arrested for plotting to bomb a subway station near Madison Square Garden in New York City before the Republican National Convention.[20] An undercover detective from New York City Police Department’s Intelligence Division infiltrated the group, providing information to authorities, and later testified against Elshafay and Siraj.[21]

Siraj was convicted and sentenced to 30 years in prison. Elshafay, a U.S. citizen, pleaded guilty and received a lighter, five-year sentence for testifying against his co-conspirator.[22]
Levar Haley Washington, Gregory Vernon Patterson, Hammad Riaz Samana, and Kevin James, August 2005. The members of the group were arrested in Los Angeles and charged with conspiring to attack National Guard facilities, synagogues, and other targets in the Los Angeles area.
Michael C. Reynolds, December 2005. Michael C. Reynolds was arrested by the FBI and charged with involvement in a plot to blow up a Wyoming natural gas refinery; the Transcontinental Pipeline, a natural-gas pipeline from the Gulf Coast to New York and New Jersey; and a Standard Oil refinery in New Jersey.[29] He was arrested while trying to pick up a $40,000 payment for planning the attack.[30] Shannen Rossmiller, his purported contact, was a Montana judge who was working with the FBI. The FBI later found explosives in a storage locker in Reynolds’s hometown of Wilkes-Barre, Pennsylvania.
Narseal Batiste, Patrick Abraham, Stanley Grant Phanor, Naudimar Herrera, Burson Augustin, Lyglenson Lemorin, and Rotschild Augustine, June 2006. Seven men were arrested in Miami and Atlanta for plotting to blow up the Sears Tower in Chicago, followed by FBI offices and other government buildings around the country. The arrests resulted from an investigation involving an FBI informant.

Assem Hammoud, July 2006.Conducting online surveillance of chat rooms, the FBI discovered a plot to attack underground transit links between New York City and New Jersey. Eight suspects including Assem Hammoud, an al-Qaeda loyalist living in Lebanon, were arrested for plotting to bomb New York City train tunnels.
Fort Dix Plot, May 2007. Six men were arrested in a plot to attack Fort Dix, a U.S. Army base in New Jersey. The plan involved using assault rifles and grenades to attack and kill soldiers. Five of the alleged conspirators had conducted training missions in the nearby Pocono Mountains. The sixth helped to obtain weapons. The arrests were made after a 16-month FBI operation that included infiltrating the group.
JFK Airport Plot, June 2007. Four men plotted to blow up "aviation fuel tanks and pipelines at the John F. Kennedy International Airport" in New York City.

Synagogue Terror Plot, May 2009. On May 20, 2009, the New York Police Department announced the arrest of James Cromite, David Williams, Onta Williams, and Laguerre Payen for plotting to blow up area Jewish centers and shoot down planes at a nearby Air National Guard Base.

Great list. Have a link?

What is the Difference Between Lasik and Custom Lasik?

March 3, 2010 - 2:41 pm 2 Comments

Glad you asked! Most people just see the work “LASIK” and assume they are the same procedure. There are differences, though, and they are important to be aware of if you’re considering laser vision correction.

Let’s start with a bit of vocabulary. LASIK is an acronym for laser-assisted in situ keratomileusis. All of that means the process of using a laser to create a flap in the cornea and reshape the cornea to return your eyesight to as close to 20/20 as possible.

Vision problems are referred to as aberrations. An aberration is the ophthalmic word for vision problems or visual distortions. Aberrations can be higher order or lower order. Lower order aberrations include astigmatism, near- and farsightedness. Higher order aberrations include night vision problems and seeing halos around lights.

The general consensus is that traditional LASIK is better suited for those with lower order aberrations. Conversely, custom LASIK can treat both higher and lower order aberrations.

Now, let’s talk about the difference in technologies. Traditional LASIK uses your prescription to determine the laser settings used in reshaping your cornea. While it works fairly well, it isn’t always as exact or precise as one would hope. Custom LASIK uses the wavefront technology to map out precise and very predictable laser settings. This technology is so amazing that it allows for corneal reshaping in ultra-minute amounts.

Naturally, this is a very brief overview of the differences between LASIK and custom LASIK. The best thing for you to do, if you’re considering laser vision correction, is to contact an experienced ophthalmologist. You want a LASIK surgeon that has the state-of-the-art equipment, technology and well-trained staff necessary to give you the best results possible.

Sure, you’ve seen the discount ads, but remember. Cutting corners on price may be mean cutting corners on equipment and technology, which may mean cutting corners where your eyesight is concerned. Don’t be stingy when it comes to your vision. Save money on dry cleaning, buying fancy coffee or eating out, instead.

Night Vision Goggles – How Do They Work?

February 17, 2010 - 2:37 pm 2 Comments

Night vision goggles give you the ability to view images in near total darkness. While mostly in use by law enforcement and military, night vision goggles are available to the public as well. This product as well as other helpful and intriguing items can be found at lookoutsurveillance.com.au.

How night vision works:

Most night vision goggles consist of an image intensifier tube, a water proof frame and a mounting mechanism. They work in the near infrared band, detecting ambient light reflected on the area being viewed. The image intensifier tube in the night vision goggles then amplifies faint light by use of the photoelectric effect. Inside the tube, photons of incoming light reach a deflector plate which ejects a number of electrons. Those electrons are then amplified into a surge of more electrons. A powerful electric field pulls the electrons towards a phosphor screen which produces light at the electron impact point. This allows the phosphor screen to produce a bright image.

Night vision goggles first came to use during World War II, then were more broadly used during the Vietnam War. Since their military conception, night vision goggles have found their place in fields of law enforcement, search and rescue and surveillance. If you are researching night vision goggles for your surveillance needs, lookoutsurveillance.com.au will have the answers to your questions. In addition to night vision goggles, they offer a wide array of other surveillance equipment sure to fit your needs.

Night vision goggles are regulated by law in certain countries. Be sure to research the ownership and usage laws of night vision devices in the country where you will be using. Some types or classifications of night vision goggles are allowed for military or law enforcement usage only. Civilians may be allowed to possess and utilize a lower classification of night vision goggles.

Lookoutsurveillance.com is a site filled with fascinating items that are sure to assist you in whatever surveillance or spy gadget needs you may have. Night vision goggles are just one of the many cool items available on the site. Hidden cameras, tracking devices and listening devices are just a few of the high tech items that are sure to help you achieve your surveillance objectives. Spy gadgets are the surveillance wave of the future.
