This issue deals with the many facets of security including hacking, IPSec for embedded devices, and counterfeit components. Brainstorm asks about the integration of solid-state lighting, while former Editor-in-Chief Alix Paultre discusses ubiquitous computing.
The US Environmental Protection Agency (EPA) introduced the ENERGY STAR program in 1992 to encourage the production and use of energy-efficient devices in more than sixty different product categories. Program results have been dramatic-a desktop computer that once consumed 30 watts in sleep mode now uses only 4 watts-with estimated savings of more than 213 billion kilowatts and $12 billion in its first eighteen years.
Significant changes are happening to European environmental regulations. While there has been a great deal of discussion and debate over the past few years, in June 2011 the European Union issued Directive 2011/65/ EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment. The new directive recasts Directive 2002/95/EC, and has come to be known in the industry as the RoHS Recast. While many of these changes seem confusing, compliance will be mandatory for any company that hopes to sell into that territory. This paper seeks to cut through the complications and lay a foundation that is easy to understand.
The August 2011 issue of ECN discusses trains, planes, & automobiles. Highlights include: “CAN in 30 Minutes or Less,” “Powering the Next Generation of Telematics and the In-vehicle Cloud,” and “Protecting Power Transistors in Automotive Inverter Design.” The Roundtable collaborative Q&A section asks “What does ‘green’ mean to you?”
Both the Lithium-ion (Li-ion) and Sealed Lead Acid (SLA) battery markets are expected to grow over the next several years. Applications with high voltage and capacity requirements are adopting Li-ion technology because of its many advantages- especially the high energy density, small size and low weight that this technology provides. Historically, SLA batteries have had a few superior technical traits, in addition to their extremely low cost, that have kept them leading the majority of the overall battery market. However, recent innovations in Li-ion chemistry has made it extremely competitive in markets that are weight sensitive and inconvenienced by SLA’s need for frequent maintenance. Many devices have required batteries for power back-up and these are primed for direct Li-ion replacement of SLA. In the medical market alone, these applications include infusion pumps, ventilators, wheelchairs and workstation carts. This paper will outline the technical and business considerations involved in converting an existing product from SLA to Li-ion.
Many medical devices are moving from simple back-up power to true portability. This creates challenges unique to medical devices and adds new advances in battery technology that can enhance and differentiate portable medical products. This white paper will look at the following advances in portable battery technology and the special considerations for medical device applications: •Lithium Ion (Li-ion) chemistries' advantages over older technology •Fuel gauging accuracy •Unique form factors using Li-Polymer •Use of Lithium Iron Phosphate for high current and Sealed Lead Acid (SLA) replacement •Sterilization of Li-ion for surgical equipment
Lithium polymer batteries have become common in single-cell consumer applications like cell phones and MP3 players, but industrial and commercial applications are now putting them to good use as well. The thin and custom shaped cells are now used in large, complex packs. This white paper is an overview of the advantages, disadvantages and guidelines for using Lithium polymer based battery packs. It looks at Lithium polymer cells versus metal-cased cylindrical and prismatic Li-ion cells and gives a brief description of battery pack construction considerations.
Battery packs are no longer a simple configuration of cells. They are carefully engineered products with many safety features. The main components include of a battery pack include; the cells, which are the primary energy source, the printed circuit board, which provides the intelligence of the system with features such as the fuel gauge and protection circuitry, the plastic enclosure, external contacts, and insulation.
