Battery Safety: Do We Need New Regulations? stars

Even months later there's been no official report from Samsung on what caused the issues they were having with the Galaxy Note 7 batteries catching fire and exploding. However, a company by the name of Instrumental, which is a manufacturing tech company, has suggested that the reason for the very dangerous flaw was that there was no space allowed for swelling in the design of the battery. This suggestion has led some to consider whether or not safer standards and regulations on cell phones and battery designs need to be put into place.

Suspicious of the reported reason for the flaw, which was that there was an issue with one of the parts of the battery, Instrumental entirely deconstructed a Galaxy Note 7. In doing so, they were able to conclude that the phone’s rather aggressive design led to the battery explosions. As noted in a blog entry, Anna Shedletsky had this to say, “What we found was surprising: The design can compress the battery even during normal operation,” Shedletsky is Instrumental’s CEO, and founder.

International Standards Organizations Governing Electronic Products

With thousands of international standards organizations across the world, may aspects of life is subject to standardization, which is a good thing for most people.  Standardizing various processes and systems helps make life safer and even more productive.  The electronics industry, in particular, is subject to thousands of global standards, and hundreds of individual regulatory bodies that create, endorse, and support these standards.

As an electrical engineer working on electronic designs, it’s important to know about some of the international standards organizations that govern electronic products.  Here are some of the well-known organizations that we find engineers work with most frequently:

Z-Wave - Popular Wireless Protocol for Home Automation and Internet of Things Devices stars

As Internet of Things (IoT) becomes the new frontier in technology, all attention seems to be turning to wireless networks for home automation. One of the key players in remote home security and automation is without a doubt the Z-Wave protocol.

Z-Wave, also known as Zwave, is a communication protocol that uses RF signaling to connect and control devices used in home automation. It is a low bandwidth protocol, capable of sending short messages reliably, from one control unit to several slave nodes connected in a network. Z-Wave protocol is made of four layers:

Wireless Standards Governing Internet of Things (IoT) Connectivity

Internet of Things (IoT) is an evolving field of computer, software, and hardware engineering that aims to bring interconnectivity to devices and human beings.  Since it is not a new field, several wireless standards, or protocols, of connectivity, have been developed since the beginning of IoT.  Different groups and standards try to solve various problems.  Depending on the application, which will dictate various factors such as range, data requirements, security, power demands, and battery life will determine the choice of one or a combination of technologies.  Outlined below are some of the major wireless standards that electrical engineers can use in Internet of Things electronic design.
