Ítem Design of medical devices for pressure ulcer prevention(DESIGN SOC, 2015-01-01) Velasquez, Alejandro; Almonacid, Ana Maria; Jaramillo, Lisa Maria; Aramburo, Mauricio; Velasquez, David; Iza, Camilo; Zapata, Luis MiguelThis paper presents a stage-gate design methodology implemented during the design of two mechatronic medical devices for the prevention of ulcers in skin. Each product required the integration of different disciplines such as mechanics, electronics and software, and went through three stages on which technical tests were performed on each stage. Afterwards a feedback was introduced into the next stage and improvements were implemented on the design. At the end both products were tested by health-care staff members, and patent applications were issued for.Ítem Optical design of a high-power LED-based solar simulator(SPIE-INT SOC OPTICAL ENGINEERING, 2016-01-01) Toro, Veronica; Velasquez, Alejandro; Velásquez, D.; Acevedo, David Felipe; Toro, Veronica; Velasquez, Alejandro; Velásquez, D.; Acevedo, David Felipe; Universidad EAFIT. Departamento de Ciencias; Electromagnetismo Aplicado (Gema)The optical design of a High-Power LED based Solar Simulator was made in order to reach the AM1.5G spectrum standards. An optical model of the light emitted by the LEDs was made and used for spectral intensities calculations and the light intensity uniformity was optimized. A class AAA solar simulator was designed using a hexagonal LED distribution.Ítem Optical design of a high-power LED-based solar simulator(SPIE-INT SOC OPTICAL ENGINEERING, 2016-01-01) Toro, Veronica; Velasquez, Alejandro; Velásquez, D.; Acevedo, David Felipe; Universidad EAFIT.
