Vehicle parts
The ECE test mark, also known as E-mark, E-mark or e-ID is a labeling for approved components of motor vehicles. It consists of a large D in a circle and each of the ECE-related check number, and states that were done for the components identified, the necessary inspections and permits and an ECE type approval. Recognize the ECE process participating States and its agencies such approval in their relations.

In addition to the ECE approval, there is the mark for motor vehicles and parts in accordance with European guidelines. This consists of a small e in the square and says that was issued for these vehicles or vehicle parts of a European type approval. The issuance of this mark is based on a different legal basis.
Basis for these tests, the so-called ECE Economic Commission for Europe of the United Nations (Economic Commission for Europe, ECE) in Geneva. The component may thus identified in Germany and Austria without a special entry in the vehicle documents carried and operated - it requires neither a "TÜV report," that is part approval (TGA), nor a EG-BE/ABE while your in the permit given area of use is maintained. In Germany, the recognition of e-labeling in § 21a of the Road Traffic is regulated.
There is no e-mark without subsequent number which follows the "E". The marking is a type approval and is not based on a manufacturer's declaration, but is issued for example by the Federal Motor Transport Authority (KBA) at the request along with an approval number. The construction and fitting of these mark is described in the relevant ECE policy.
Auführung:
The mark consists of a circle, inside which the letter "E" and the number of the state are located, has granted approval and the approval number in the vicinity of the circle, where applicable, the number of the international agreement with " R "and if necessary additional characters.
A certification mark may be affixed only to vehicle parts or equipment, which also meet the requirements of the permit. A character that can lead to confusion due to similar appearance with the ECE test mark may not be available on vehicle parts. For operation of devices without the "e" - are operated or "E" mark in a motor vehicle, under certain circumstances, the approval shall expire.

TV
The most important question here must be: How big should it be? are self-giant flat-screen TVs are now relatively cheap, but it should also be according to the living room spacious. Rule of thumb: Screen size times three is the best sight distance at high definition television on (HDTV), it may be less. Plasma or LCD? This is now a matter of taste. However, plasma devices are now considered obsolete technology. Even if they are still produced and new devices are offered again and again so many manufacturers have now adopted this technology and offer only LCD sets. Plasma TVs often show beautiful colors, usually consume more power, but not always.
Since helps to compare them. Devices with 100 hertz technology should be selected if it is seen on large TV sets a lot of sports, movements appear to be smoother. Most devices have a built-in receiver (tuner) for digital television, but you should make sure what is needed: DVB-C, the device is equipped for cable TV, DVB-T stands for Antenna TV, needed for DVB-S, however to a satellite dish.

Digital Camera
In the resolution, it is hardly to still, for printing up to DIN A5 five megapixel range, twelve for amateur photographers almost exaggerated. Zoom can not get enough of it, so we collected as distant subject up. (But beware: optical zoom is the right zoom, the digital zoom simply counted up only an existing image, the image may look pixelated and can also be blurred.) Expressed generally, a region (such as "28-120") while the first number is important: 35 or less it should be, otherwise you get into interior spaces not much in the picture. Do not be confused: The figures are based on the old small-screen film format. As a memory card SD card is the most common and the most favorable. Which battery system should it be? Standard batteries in the battery formats are favorable, but we also quickly tired. Cameras with lithium-ion batteries are more expensive, they last longer. Regular digital cameras are already there for 100 €.

Sat Nav
If you buy a scout for the car is the size of the maps critical: Is it or is it only Germany and Austria and Switzerland or Europe? Not all Navis calculate traffic jams and detours, some costs this feature a monthly fee. Some Navis lure with features such as speakerphone and photo viewer, but who really needs it? Warning: Many devices warn of speed traps, strictly speaking, is prohibited and may result in a fine.

Mobile
can and performance category, from pure phones to smartphones, which can also play with pictures, or surf the Internet - devices are available in every price. Which device should it be thus depends on the application. To give away is the best pre-paid tariff, in which charges a credit and used up. This protects against exorbitant bills.

Blu-Ray-Player
The successor of the DVD delivers crisp images, there are players already under 100 €. But beware: Some players download for several minutes until the movie finally starts. Has too many Beschenkender DVDs, embellished the function * Upscaling these films. With a USB connection, one can for example also look at vacation photos on your TV, Internet access is a rather dispensable Release Extra. Do not forget the HDMI cable is included for connection to the TV set in the rare, this should best be treated mitgekauft, because only then can the player play his entire image quality.

MP3-Player & Co
The music player to take away are tiny, but sometimes suffers from usability. For an adult often slightly larger MP3 players are better suited. If possible, just try out. Two gigabytes of memory (2GB) are sufficient for about 400 songs, more space is great, but also more expensive. The important thing is the battery life should not be less than five to six hours, otherwise the player is always empty when you need it. Again, there are already devices from 30 €

Laptop or Notebook
On portable computers, it will first and foremost on the size. If the device is often taken and on the go without recharging also used, or has a permanent place on the desktop? The practical netbooks do have a small screen, but it is pretty easy and cheap and endure long hours on one battery charge. Current games run on it, however. On most notebooks, the Windows operating system is pre-installed, but are often small devices with Linux. Here is to consider whether the recipient of the device can handle it. Tablets are that are flat computers that do not have a keyboard, operated with the finger on the monitor: Brand new at this point. For surfing the Internet, they are ideal for writing, but rather unsuitable.

* Upscaling is a form of television technology in the processing of the image signal, extrapolated to the origin of the resolution of footage on a higher image resolution is, by the lack of picture elements (pixels) of finer resolution can be interpolated. It added no new image information, but then the formation of a visible grid pattern is prevented which would result if the source material would be stretched only to the new resolution and the missing pixels were not added later.

This method is often used in home cinema systems, operating at the HDTV-enabled output devices with material in PAL resolution, which comes from eg a DVD player. Upscaling is backed by special chips in real time, with the output signal is not stored. The upscaling is, contrary to the high conversion of a material in which the output signal are not necessarily created in real-time needs, but is saved for it.
