The security of devices in the Internet of Things (IoT) is a key challenge for developers today. Protecting the integrity of access to, and data within, the enterprise networks that connect up the IoT is essential for both companies and customers. With many different wireless technologies being used to make these connections, there are many different ways for hackers to attack the network.
Today's business pace is faster than ever before and with competitive market conditions and rising consumer expectations, designers are striving to get their products to market quickly and efficiently.
“Smaller, faster, prettier” – these are the main criteria for today’s electronics. A profitable lead for manufacturers, but also quite challenging for design engineers, that have to fit everything together in a much smaller environment. Put safety on top of these requirements and the story is getting even more complex. Complex for both designers and manufactures and ultimately relevant for the end customers, who expect their products to be not only fully functional, but also safe.
Every day, consumers depend on unseen technology that allows them to safely navigate their day. The daily routines of turning on a light switch, checking email, or driving to the grocery store can easily be taken for granted. But, none of these seemingly minor tasks could be accomplished without the safeguarding that has been designed into the daily lives of consumers.
Electrical fuses were originally developed to help protect telegraph stations from lightning strikes. These first fuses were simple, open-wire devices, followed in the 1890s by Edison’s enclosure of thin wire in a lamp base to make the first plug fuse. By 1904, Underwriters Laboratories had established size and rating specifications to meet safety standards. Renewable type fuses and automotive fuses appeared in 1914. In the 1920s, manufacturers began producing very low amperage fuses for the burgeoning electronics industry. Today, the fuses used in electrical/electronic circuits are current sensitive devices designed to serve as the intentional weak link in the circuit. Their function is to provide protection of discrete components, or of complete circuits, by reliably melting under current overload conditions, much like those first fuses used at telegraph stations.
