Digital cameras are liable to rust

Snow and freezing temperatures are bad for every digital camera: moisture threatens the electronics and can lead to rusting of the sensitive lenses, the cold makes the most of the batteries to create considerably.

Who wants to make a lot of pictures with a digital camera should therefore think of replacement batteries. In comparison, lithium batteries show in terms of stability to temperatures considerably more robust than alkaline batteries, such as the online portal has tecCHANNEL found after a test of ten 1.5-volt batteries.

According tecCHANNEL lose energy cells to alkaline base at zero degrees Celsius on average about 30 percent of their operating one. Lithium-based models lose an average of only five percent of their power. For lithium batteries currently cost about 2.50 per cell. Alkaline batteries in discount stores for consumers receive about 21 cents each.

Winner was the 1.5-volt lithium battery Energizer Ultimate L91 as AA / AA and the L92 as micro-cell (about 2.50). According to test results show the loss of capacity at zero degrees to 21 degrees was only minimal. The battery capacity was reduced by up to four percent (L91) and nine percent (L92).

Empty batteries are annoying - it is really expensive but if liquid gets inside the camera. By moisture in any form, as fog, rain, snow or Brandungsgischt, the camera can be damaged electronics. The safest protection is a suitable underwater housing, the Photographic Industry Association advises in Frankfurt.

If the camera is wet despite careful handling, they should as soon as possible with a lint-free cloth and wiped dry, as this can arise, for example, rust on the metal parts. The front lenses of the lenses are cleaned according to experts, the best with special cloths. In no case should the paper handkerchiefs are used, since it contains small wood particles scratch the glass.

Where shrinks the CeBit?

Where shrinks the CeBit?

It is a serious setback for the CeBIT. The global economic crisis hits the big high-tech fair in Hanover with full force - it will focus on heavy losses in the number of exhibitors. An analysis.

The number of exhibitors is down by more than a quarter to around 4300 - and thus from the 1990 level. Many companies use to cut red tape, save money when marketing and waive a CeBIT show. This is the hard-throat competition in the industry. And companies especially from the consumer feel at CeBIT not the right place and put on other shows like IFA electronics fair in Berlin.

The high-tech industry has been hit by the recession in full, even the last boom in consumer electronics. Companies and consumers cut their spending on massive purchases of new computers and mobile phones, added is the sharp price competition. Thousands of jobs in the sector are eliminated, even Microsoft deletes the first time in its history, dramatically jobs.

For the organizers to exercise in optimism, "4300 exhibitors from around the world are given the global economic crisis a success. Companies that their marketing budgets must be set to zero, this year, however, not be in Hannover. Marketing is at the first save, "said fair board member Ernst Raue.

He is convinced: "We will this year see a very efficient CeBIT. The companies that are coming, and the visitors have come to think very carefully and connect with the show in Hannover great hopes. "The high-tech fair shows ways out of crisis.

forgo an appearance at CeBIT this year, especially many small hardware manufacturers and telecommunications equipment from China, Taiwan, South Korea and Hong Kong. This was the main cause for the decline in the number of exhibitors, "said Ernst Raue, member of the German CeBIT organizer Messe AG, on Friday. "The crisis exacerbated an already tough market where repression once more. Many companies are simply not there. "

However, return some renowned companies from the Hannover Fair in the back - for example, the electronics giant Toshiba, the printer specialist Kyocera, the world's largest telecom equipment supplier Ericsson and the storage media manufacturer TrekStor.

Also the mobile phone giant Nokia is missing again, the Group is better to house exhibitions and - like the rest of the industry - at the Mobile World Congress in Barcelona, which takes place each year only a few weeks before the CeBIT. Overall, the CeBIT exhibition is compared to the previous year by almost 20 percent to around 200 000 square meters.

The associated revenue losses could tear deep holes in the balance of the fair society. For the next CeBIT Hannover Messe exhibition industry, the number of exhibitors this year is stable, the most important event of Messe AG.

According to media reports, the company last year made a loss of tens of millions, are for fear worse numbers this year. The fair has already responded with an increased savings program. The huge exhibition center - the largest in the world - is utilized only rarely.

In the boom year of 2001, the CeBIT still an area of approximately 430 000 square meters and nearly 8100 exhibitors - however, the industry has changed dramatically since then and seen some consolidation phases.

CeBIT 2009 will seek ways out of crisis and show how companies can reduce use of information and communications technology costs. "The IT industry can offer products and solutions contribute significantly to the crisis, because it makes the company leaner and stronger," said the president of the industry association BITKOM, August-Wilhelm Scheer. Raue said, go at CeBIT more than ever to new business and the decision of companies to act now to strengthen and look to the future.

A little gloss on the CeBIT might bring "Terminator" Arnold Schwarzenegger. The California governor and former Hollywood star coming to Hanover this year, the U.S. state is the partner country of CeBIT 2009. Schwarzenegger was at home but has huge problems: Only with a Nothaushalt and tax increases the threat of insolvency of the state to be averted.

Dynamic 6-Pack

Dynamic 6-Pack

Notchback sedans are not exactly renowned as a dynamic design icons. The fact that there is another way, the Japanese have shown with the Mazda6. With the right engine of the Mazda also holds what promises the form.

Most sedans are fairly conservative and conservative rolling in - the current Mazda6 is because one of the few pleasant exceptions. Hard to believe when one remembers the former bores 626th The current design follows Mazda's Nagare design language, inspired by its dramatic flowing lines of nature.

The front of the almost beefy wheel arches, the front grille and headlights remind the narrow slightly at the own RX-8. The rear of the proposed works just the tailgate taillights harmonious as the whole car. A pleasant side effect of the harmonious lines and subsoil of the disguised: the drag coefficient of 0.27.

Offers inside the Mazda6 sedan in the version space for up to four passengers - albeit with somewhat limited rear headroom. More than two people should not expect, however, the back seat - otherwise it is somewhat narrow. And a little more contour seats in the rear could tolerate. Front seats are tight so convenient - even for long distance travel that can be fit and fresh.

The operation is simple and straightforward, clearly marked and at night red-backed gauges can see well and all the buttons and knobs are easy to reach. The quality feel is as solid as it is for a Mazda one - to the feel of the materials used. The steering wheel can be adjusted in three dimensions - even more people find good space. What is lacking are enough racks.

With 519 liters of luggage compartment of the Mazda6 is relatively spacious and in the middle of his class. The Ford Mondeo is about 550 liters, 565 liters of the VW Passat, the C-Class from Mercedes to 475 liters. As in a saloon is not uncommon to - after all, broad - loading opening, despite the wide-opening door but not exactly lush. To open the trunk, you have to either press the remote control of the ignition key, or the slightly fiddly little button in the third tail light. And the sill its construction is relatively high.

The start is the Mazda diesel engine by pressing a button. After a short delay, the cold engine, first as nails out loud and rough, like a tractor. This sound and Ruttelkulisse shall, however, quickly - and then the 2.2-liter self-igniting a powerful and sophisticated engine. The volume forces itself even at high speeds is not audible in the foreground and initially also by the vibrations can be felt quickly any more.

In three versions, the new base engine, with its 2184 cc's possible. It starts at 125 hp and 185 hp at the end of our test car. The power rises significantly in horsepower and torque (400 Nm in the 185-hp version) - and according to the performance. The 185-horsepower engine accelerates at least 1.5 ton empty notchback sedan within 8.3 seconds from 0 to 100 km / h, top speed is 218 km / h.

At least the DIN consumption remains despite the performance almost the same: 5.5 liters of diesel per 100 km are in the Mazda 125-hp engine, 5.6 liters for the 185-horsepower engine. In the test, the Mazda came with about a liter more well clear. As with most cars from Japan is the flap of the tanks are not involved in the steering, but must be unlocked with a lever on the floor in front of the driver's seat.

According fast it is proceeding with the turbodiesel. At no time do we have to be underpowered feel. Overtaking the Mazda provides a fast and fearless, slopes are no more a problem as brisk highway driving. Only shortly before reaching the top speed is a little tough. In addition, the sedan is pretty easy to turn and delay shifting to drive - from about 1500 rpm. it also accelerates from higher gears to muck out quickly and without.

The course can be switched with precision and short distances, only very rarely is a lightweight heel to notice. The tunnels themselves are very well adjusted to the characteristics of the engine - in the city to get out without much Schalterei and on the highway is also the engine at high speeds - and if he is not just about the 200 mark drives - always a comfortable speed range.

Overall, it is driving the Mazda6 agile and very good-natured. Before it gets tight, does one usually one of the many electronic security systems. At the start - for example at traffic lights - helps on slippery surfaces the traction control. The precise steering could provide some more feedback from the road, but every move follows willingly and consistently. The cornering is designed to understeer a bit more. But you would not be as drivers hardly notice anything at all, because even here, the electronics intervene early enough.

The suspension is tuned more comfortably and confidently absorbs most bumps. When load changes, there is little body roll. With a base price of 28,800 euros of the 185-horsepower Mazda is not a bargain pronounced, however, lies in his class well in the race. A VW Passat diesel with 170 hp comes at a much leaner standard equipment already at least € 29 100, a Honda Accord i-CDTi 150 PS will cost from 28 675 € and for a Opel Insignia 2.0 shell out 160 hp must be at least 29 755 euros.

A few check marks in the options list to get but also in the Mazda is a must. Who Bi-Xenon headlights will, it must at the very dynamics package (2500 €), together with others Blind Spot Information System, or sports optics order. A permanently installed navigation system will cost € 2300 to once again lush.

Where Opel travels without his mother?

Where Opel travels without his mother?

Opel is still a part of General Motors, the third largest car manufacturer in the world. But in Germany inspiron e1705 battery, calls to the separation of the Americans. But can Opel ever exist without the parent company?

Theoretically, this is at least possible. For the group of companies from General Motors (GM) is not as solid as it seems from the outside. According to an Opel spokesman for the engines, transmissions and body parts for the vehicles to be built in his own works. Smaller components are manufactured by "independent suppliers," one of which is next to Bosch, Conti and Schaeffler also Magna, the spokesman continued. Thus could the GM's European subsidiaries operate largely independently.

Another question are the patents, that is, the rights to use the technique to the Opel could previously access restrictions. These include inventions such as engine technology, chassis development, aerodynamics, inspiron e1405 battery electronics. "The patents are in a GM-wide patent pool", an Opel spokesman.

These patents should GM have reportedly pledged most of the U.S. government to get the needed funds for bridging the current production. This is also a reason why the federal government is involved in the Opel rescue so strong. In the morning, "said Angela Merkel Bundeskanzerlin: The company forms part of the GM parent company is essentially the U.S. government. And so it goes without saying that a Federal Government is in talks with the U.S. government must care more than in all the ordinary cases. "

The U.S. government could be convinced by the Germans to pass an independent Opel group rights. But General Motors will agree? That would say that GM's subsidiary still owed about three billion dollars. GM Europe President Carl-Peter Forster, who hopes to get the patents or at least the full inspiron 9400 battery rights of use.

The important question for this week is Opel, which makes the three candidates the race. From the German side is far preferred Magna. The Austro-Canadian car manufacturer operates factories for car parts in Europe and is now manufactures car parts for Opel. Magna also has reworked his concept after the critique of politics: First, the suppliers had planned to strike in Bochum in 2200 of about 5,000 jobs and shift production to the Astra Rüsselsheim. The new details are not yet known, but have already been well received by government.

The GM group in the U.S. seems so far the financial investor Ripplewood to be the favorite among the three. The investor would be there only on the return that all business decisions to remain with GM and therefore Opel.

Fiat will have a hard time. Although Sergio Marchionne seems to strive to present the most lenovo x60 tablet battery committed to the acquisition, but is the American parent company, most likely across. The reason: Along with Chrysler, Fiat is now a competitor for GM in the American market.
