The present disclosure describes a system, method, and computer readable medium for providing information of a calling party to an alert party, wherein the calling party is in communication with the receiving party in a communications network. The folded pendulum can be a monolithic pendulum and is positioned in the vertical configuration. Also, a method of generating hydrogen and electrical power that includes generating electric power from a first portion of a hydrogen gas mixture with a protonic ceramic fuel cell, and generating purified hydrogen gas from a second portion of the mixture with a hydrogen separator. The invention provides an EEM spectroscopy system that is not a high resolution such as a laser or lamp based excitation system, but instead uses a lower resolution, lower power LED system.
