How To Stay In Shape Forever

The core of true fitness lies in your hearts strength. Your heart is one of the most valuable pieces of equipment in your body. This little pump the size of your own fist literally creates life for your body. You can survive a shock to your brain, but if your heart stops, the chances of survival diminish drastically. If your heart is weak, your whole body is weak. It represents the ultimate power both internally and externally. A strong heart helps you lift weights easier, helps you run faster, jump higher and creates a better athlete or a better exercise devotee.

If all the above is true, how come a lot of us worry about the size of our biceps instead? I believe this is true because one way or another, a lot of us believe it is harder to exercise the heart then it is to work other muscles. When you weight train for instance, you dont sweat as much as when you participate in aerobics. This is true because the system that operates during weight training is anaerobic or without oxygen allowing the body to use less energy. Cardio training like cycling, running or aerobics uses much more energy because the consumption of oxygen is higher resulting in excessive sweat.

One way to keep an excellent healthy heart is to exercise aerobically to maintain proper cardiovascular health. In other words, you must stress or cause your heart to work harder than usual to keep arteries clear and to improve pumping power as well. weight training is not the best method to exercise the heart. It affects the heart somewhat, but not enough. Make sure that you choose the right exercises that focus on the right system in your body. What ensures results is selecting exercises that directly affect the areas, muscles or system needing improvement. This is one way to maximize results. To be in shape forever then, its imperative for the health of the heart to be impeccable.

CE Marking Electronic Products

All electronic products sold within the european Union are required to be CE Marked. However I find that there is a large amount of confusion and misunderstanding, with people struggling to find what is required of their product.

The legal responsibility for compliance with the CE mark remains with the company that either owns the manufacturing rights for the product, or imports it into the EU. It is not possible to "outsource" this legal responsibility to a third party. Test and compliance houses can provide third party validation that a product has been produced and tested against the required standards. Test houses can also advise on the standards against a specific product should be tested, bear in mind that it is ultimately you who has responsibility for compliance so some research and general understanding is advisable.

From the UK Department of Trade guidelines on CE marking a definition of for CE marking is "a declaration by the manufacturer that the product meets all the appropriate provisions of the relevant legislation implementing certain european Directives".

Typical areas covered by the legislation are EMC, EMI, Safety and Environmental laws. EMC - The unwanted Electromagnetic energy generated by your product. There are normally limits for both conducted and radiated emissions. EMI - The ability of your equipment to withstand electromagnetic interference from other sources without malfunctioning or interrupting its normal operation. ESD - Electrostatic Discharge testing involves testing the ability of your equipment to withstand the high voltages that occur when static discharges occur. A typical source of ESD is when a person walks on a carpet, generating a few thousand volts of potential. Safety - Safety testing can cover the electrical, mechanical and fire related safety tests. Environmental - The most well known environmental legislation is the RoHS directive covering hazardous substances such as lead, however there is also the WEEE directive covering end of life disposal. An up coming piece of legislation is the energy Using Products directive which will come into force in the near future.

In addition to the areas outlined previously, some products such as wireless equipment are required to meet specific legislation, with testing required by an authorised body or so called "notified body". A common misconception is that ISM or so called "license free" radios do not require type approval testing - this is not true. As this testing can be expensive it is wise to research the costs prior to commencing a development, as it can effect the direction you take. For example it is possible to buy pre-approved modules, removing the burden of type approvals.Equipment that does not require testing by a notified body can be self certified.

A "technical construction file" should be created. The TCF contains all the technical details of the product, including assessments of legislative compliance with test reports from the appropriate test houses or internal testing.

In addition to the legal requirements you may wish to or are contractually required to test and comply with industry or military standards, such usb, bluetooth, IP ratings, MIL810 etc. It is important to remember that while these may add a level of credibility to a product they can incur large costs. In a similar manner to type approvals it is wise to get preliminary costing for the approvals phase. While these voluntary standards add credibility to a product, they will have an impact on the unit cost of your product.
