    Integration of head-up display system in automotive industry: A generalized application
    (SPIE-INT SOC OPTICAL ENGINEERING, 2013-01-01) Alejandro Betancur, J.; Osorio, Gilberto; Mejia, Alejandro; Alejandro Betancur, J.; Osorio, Gilberto; Mejia, Alejandro; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
    Throughout the development of the automotive industry, supporting activities related with driving has been material of analysis and experimentation, always seeking new ways to achieve greater safety for the driver and passengers. With the purpose of contributing to this topic, in order to contribute to this subject, this paper summarizes from past research experiences the use of Head-Up Display systems applied to the automobile industry, covering it from two main points of discussion: the first one, from a technical point of view, in which the main principles of optical design associated with a moderate-cost experimental set up are brought out; and the second one, an operational approach where an applied driving graphical interface is presented. Up to now, the results suggest that the experimental set up here discussed could be adaptable to any automobile vehicle, but it is needed further research and investment.

    Smart army helmet: A glance in what soldier helmets can become in the near future by integrating present technologies
    (SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Betancur, J. Alejandro; Osorio-Gomez, Gilberto; Mejia, Alejandro; Rodriguez, Carlos A.
    Nowadays, technologies like improved reality systems, sensing systems and communication systems, are moving forward with a high rate. This situation is very convenient for military groups that are trying to access modern technologies. According to that, it is very feasible to propose the development of electronic devices that increase the possibilities for soldiers to be alive during an armed conflict, providing them with information that can bring strategic benefits on the combat field, which is the main goal of this research. Therefore, it is proposed in this paper the early design stages of a smart army helmet, focusing in their low cost production; however, all the electronics stages specified here are proposed as prototypes. © 2014 SPIE.
