    “CgMed”: Diseno y construccion de plataforma para determinar posicion del centro de gravedad en bipedestacion
    (2014-04-23) Cuesta-López, L. F. (Luisa Fernanda); Lema-Calidonio, J. D. (José Daniel)
    Stabilometry is a fi eld that comprises a series of studies, from which the specialist can study the location and trajectory of the center of gravity of a patient in standing position. It is a widely used technique among health industry professionals. It is also used to diagnose musculoskeletal system diseases and to establish personalized training and rehabilitation sessions for each patient. This project, presents the design of a stabilometric platform with four sensors and a metal structure in SAE 1010 steel, designed to withstand large deformations and efforts. The acquisition and conditioning of the signals begins with an amplifi cation and fi ltering stage. Then, using a data acquisition device, the data is uploaded to a graphic interface in LabView in order to calculate important variables and factors, such as the Romberg’s coeffi cient. Satisfactory results were obtained both in the design, modeling and construction of the device, as well as in the performed stabilometry tests.

    Diseño y construcción de un fonocardiógrafo digital con visualización en LabVIEW
    (2014-04-18) Osorio-Valencia, J. S. (Juan Sebastián); Cuesta-López, L. F. (Luisa Fernanda); Gómez-Maya, F. (Felipe)
    The auscultation of the heart noises has always been an important tool in medicine, a good diagnosis of illnesses related to the heart valves should be given from a phonocardiogram able to give the doctor a reliable information of the patients situation. The design presented is a phonocardiograph capable of amplifying and filtering the acoustic signs derived from the heart. After an analog to digital conversion of those signs the information is sent by serial port to a graphic environment in LabVIEW for its registration and analysis in real time
