We spend a lot of time in our cars; many people consider it just a means of getting from point "A" to point "B". But there are some great creature comforts and downright entertaining hi tech gadgets on the market today. These gadgets won't make your car Kit from Knight Rider (well maybe one will), but the article addresses a few items to consider, but obviously there are a lot more.
 
HD Radio is one of the most impressive and practical gadgets available. It provides a huge technology lead from what we have become accustomed to with AM and FM radio stations into what is now digital radio.   The cost is all on the front end with the equipment, there is no monthly subscription fees, no hissing associated with radio and many more stations to choose from.
 
FLIR Systems developed the PathFindIR to provide thermal imaging that increases nighttime visibility. The device is shown through a camera and it allows the driver to see people, animals or whatever up to 2000 feet which is way further than we currently see in the dark. The cool think is you can continue to see that distance through snow, rain and snow. As you can imagine it's been tested by the military too. This is a cool gadget, but for the price you will have to do some justification on why you need it.
 
Garmin has a free download that is available only on its nüvi GPS system, its called ecoroute. Ecoroute measures how environmentally friendly your driving is, rating you between 1 and 100 so you can see how well you are doing. It gives you real time feedback, which ideally saves you money and the environment all at once. 
 
The Koolatron Compact Cooler gives you a place to put those cold ones and keep them cold, or a sandwich, or a...heck this thing is a refrigerator for your car!  It was designed to fit in a tight place like between seats or behind one of them. It plugs into your cigarette lighter and keeps food 40 degrees cooler than the outside temperature.
 
Now if someone can just make a car stove to go along with the refrigerator we would all be set, for now we will have to be satisfied with frying eggs on the hood. In a later article I will be taking a look at some of the cool spy gadgets available on the market.

Night Vision against Thermal Imaging

!±8± Night Vision against Thermal Imaging

Describes advantages and disadvantages of night vision technologies See more at: www.flir.com Or, if you are in law enforcement and would like to help FLIR by taking a survey, please do so here: www.bit.ly Night vision goggles and scopes make images from visible light, just like your eyes. So, their familiar green-cast images provide excellent situational awareness at night. Unfortunately, magnifying the amount of light in an image is only part of the solution to true night vision. The critical element they don't address is visible image contrast. That's what you really need to be able to see at night. When a target is brighter than its surroundings it has good visual contrast, and is easy to see. When a target doesn't have good visual contrast you can't distinguish it from its surroundings. No night vision scope can reveal contrast that's just not there. Thermal cameras see heat, not light. The more heat an object gives off the more thermal contrast it generates, and the easier it is to see. Everything on Earth gives off heat, and things like people, animals, and car engines lots of heat. So their easy to see, even through camouflage. Atmospheric conditions, like smoke, rain, or fog, reflect light, making night vision goggles and scopes even less effective. But thermal cameras see through these obscurants and clearly. Night vision goggles and scopes also need to have the right amount of light to work well. If light levels are too low, like in rural areas and when looking ...

Thermal Cameras

!±8± Thermal Cameras

Thermal cameras are devices that form images using infrared radiation which is like a common camera that forms an image using visible light. These cameras are also known as FLIR (Forward Looking InfraRed) or an infrared camera. These cameras operate in wavelengths of about 14,000 nm (14 µm) instead of the 450-750 nanometer range of the visible light camera.

Thermal cameras are being increasingly used in applications such as border security, high value site protection, industrial security, perimeter security, force protection, coastal surveillance, deployable security, asset surveillance, port security, airport security and urban surveillance. A thermal camera converts the thermal energy emitted from a body into a visible image. This image is then represented as a thermograph that is a picture of heat.

Thermal cameras are much more expensive than the visible-spectrum cameras. It is the process of capturing the heat from an object, which is undetectable to the human eye, and converting it into an image that can be observed. This process does not require any light and can function perfectly even if the surrounding lighting conditions is bright or dim. These cameras provide added vision within the infrared spectrum which in turn broadens the vision of objects viewed. In other words, thermal cameras help in seeing the difference in thermal temperature of objects viewed. These cameras also help in detecting and interpreting emissions and also provide users with images, even in conditions of low-visibility or complete darkness.

There are two basic types of thermal cameras viz; Un-cooled and Cryogenically cooled. In the former type, the infrared-detector elements are equipped in a unit that operates at room temperature. This type of a camera does not make any noise, activates immediately and has an in-built battery.

The Cryogenically cooled type of thermal camera are more expensive and more liable to damage from rough use. It has the elements contained inside a container that cools them to below 32 F (zero C). Its incredible resolution and sensitivity help in viewing a difference as small as 0.2 F (0.1 C) from more than 1,000 ft (300 m) away, which is sufficient to tell whether a person is holding a gun at such a huge distance!
