Evaluation of a Low-Cost Videolaryngoscope: By Conducting a Manikin Study

Background: Existing videolaryngoscopes do not meet the needs, budgets, and cleaning protocols of low- and middle-income countries. To solve these problems, a new videolaryngoscope, the Goodscope, has been developed which is less expensive, reusable and easy to clean. The aim of this study was to evaluate the efficacy of the Goodscope compared...

Thermal-Performance Evaluation of Bicycle Helmets for Convective and Evaporative Heat Loss at Low and Moderate Cycling Speeds

The main objective of the study was to investigate the thermal performance of five (open and closed) bicycle helmets for convective and evaporative heat transfer using a nine-zone thermal manikin. The shape of the thermal manikin was obtained by averaging the 3D-point coordinates of the head over a sample of 85 head scans of human subjects,...

Design, development and validation of more realistic models for teaching breast examination

Our objective was to design, develop and validate better clinical breast examination (CBE) models addressing the deficiencies of previous models. Detailed research and a<br/>methodological design approach led to the development of a new technique for creating lifelike models for teaching CBE. Six multi-layered breast models representing a range...

Development and assessment of two fixed-array microphones for use with hearing aids

Hearing-impaired listeners often have great difficulty understanding speech in situations with background noise (e.g., meetings, parties) . Conventional hearing aids offer insufficient directivity to significantly reduce background noise relative to the desired speech signal . Based on array techniques, microphone prototypes have been developed...
