This work presents the implementation of an experimental platform for monitoring the power consumption of mobile devices, such as smartphones, notebooks and netbooks. In this platform, a robust electrical circuit is connected to a data aquisition module for power measurements via a virtual instrumentation implemented in the LabVIEW software. The computer system state was measured by means of operating...
A system for the interrogation of fiber Bragg grating (FBG) sensors using a strain-tuned EDF laser with linear cavity is described. An optical switch is spliced to one end of the laser cavity and connects one of two high-strength draw-tower fiber Bragg gratings (DTGs). The gratings are simultaneously tuned by a stretching device and act as the end reflector of the laser cavity. By applying a ramp...
