A Singular Advance in Conversion of Acoustic Signals to Electrical Form: The Electret Microphone

On 29 April 2010, the Franklin Institute held its ceremony in Philadelphia, Pennsylvania, to honor Gerhard Sessler and James West with Franklin Institute medals for their invention of the practical electret microphone. The day before the ceremony, a symposium took place at Temple University in which Dr. Flanagan summarized some of the history of the electret microphone. In his talk, Dr. Flanagan shared his perspective on invention of the device that is a commodity nowadays and how the initial incentive was telephony. Later, Dr.

IEEE Launches the IEEE eLearning Library

IEEE has announced the launch of the IEEE eLearning Library, composed of nearly 200 short, online courses in core and emerging technologies. Each course was developed and peer-reviewed by subject experts and awards continuing education units (CEU) or professional development hours (PDH) upon successful completion. IEEE eLearning Library courses can be viewed in the IEEE Xplore digital library and accessed via the IEEE Learning Management System (LMS).
