Top 10 Wireless Charging Developments in 2012
2013 New Year's Power Celebration
5: UL Offers the Qi Logo Certification Service for Wireless Charge Devices
Underwriters Laboratories, Inc. (UL) has commenced a logo certification service for the wireless charging standards, "Qi". UL Japan has become Japan's first company to be certified by Wireless Power Consortium ("WPC") as a third-party certification organization. WPC formulates the international standards for wireless charging compatibility of mobile devices and promotes dissemination of these standards. To display a Qi logo on a product, passing a qualification exam conducted by an accreditation organization is required. "Qi" is the international standard for wireless charging by the electromagnetic induction method, and was formulated by WPC in 2010. Qi-certified products can be charged with any types of Qi-certified rechargers, irrespective of the manufacturers.

4: Global Technology Power Players Unite to Form Alliance for Wireless Power Creating Spatial Freedom in Consumer Electronics Charging
Wireless technology specialists Samsung and Qualcomm Inc. have joined other technology leaders to form the Alliance for Wireless Power (A4WP). The independently operated organization's mission is to promote global standardization of a wireless power transfer technology that offers spatial freedom, to develop product testing, certification and regulatory compliance processes, and to foster industry dialogue with regulators on wireless power policy development. The alliance is targeting a broad base of consumer electronic devices to establish a worldwide wireless power technology ecosystem. The A4WP will focus on a new wireless power transfer technology that provides spatial freedom for charging of electrical devices in cars, on tabletops and for multiple devices simultaneously.

3: Wireless Power Consortium Extends Qi Standard to Include Longer Range Magnetic Resonance Wireless Charging
TheWireless Power Consortium announced that the Qi open wireless charging standard is capable of providing full support and compatibility for longer-distance magnetic resonance technologies. Wireless charging stations such as those that can be built into furniture, tabletops, cars, or found in charging pads, typically use magnetic induction or magnetic resonance transmitters to send power to the portable devices they're charging. Having the flexibility to choose from multiple transmitter designs allows companies to offer a wide range of Qi product types in consumer electronics, home appliances, furniture, automotive and other markets.

2: Alliance for Wireless Power Rolls Out Flexible Wireless Power Specification
Alliance for Wireless Power (A4WP) announced that the technical working committee has approved a more flexible wireless power specification that will allow consumers to charge their mobile devices on a variety of compatible surfaces. The A4WP specification is based on a concept of spatial freedom, which extends wireless power applications beyond the accessory or add-on market to fully integrated solutions in the device as well as surfaces such as furniture and automobiles. The A4WP specification brings a number of unique benefits to the wireless charging ecosystem.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
