A task force of the Institute of Electrical and Electronics Engineers is investigating the possibility of feeding power over Ethernet data lines. Although computer systems will not be able to be run from one all-purpose Ethernet/ power outlet, many other small Internet-enabled devices could be. For example, access points for wireless local area networks could be installed without requiring a...

IEEE's Power Electronics Society (PELS) "helps in the development and effective application of power electronics technology." Power electronics is definted as "the application of electronic circuits to energy conversion," which is used "everywhere you look," including in computers automobiles, telecommunications, space systems and satellites motors, lighting, and alternative energy. The PELS...

In this case study from researchers at Hewlett-Packard, the power characteristics of a handheld computer were evaluated. The purpose of the study was to shed some light on how battery operated handhelds consume power under representative workloads, possibly leading to more efficient "low-power design and power management." Experimental procedures and results are presented for extensive battery...
