Importance of pre-requisite cognitive
All research must be based on the latest scientific knowledge. In an age characterized by the dissemination of information, it was unthinkable to ignore the advances of knowledge before embarking on research involving humans. This need to keep abreast explains the many international conferences and publications in scientific and building databases on computer networks. Staying informed is indeed a real need as the renewal of knowledge is important and timely. This makes replacement very quickly obsolete knowledge that are not regularly updated. The duty to keep informed as to this figure as a general duty of the physician.
However, research thrives on originality, the greatest discoveries are often made of solitary spirits or happy accidents. This strong knowledge dissemination can sterilize risk research that would appear too innovative or too far outside the prevailing opinion. Do not deny that behind the apparent rationality of research based on rigorous analysis of the state of knowledge, also hide the effects of fashion or chapel thoughts.

Engineers sometimes joke that a cable is a source of potential trouble connecting two other sources of potential trouble. Now, with low-cost, easy-to-use RF systems on chips, you can eliminate that intervening cable in many limited-distance applications. These applications include situations in which it would just be nice to avoid a cable, such as between a handheld control box and the unit it is managing, and those in which a cable would defeat the application, such as with a remote-keyless-entry (RKE) lock for a car or house. In many ways, though, cheap and easy RF links are enabling new applications that are sometimes possible, but usually impractical, with wired links.
