Using arrays with digital MEMS (Micro-Electro-Mechanical System) microphones and FPGA-based (Field Programmable Gate Array) acquisition/processing systems allows building systems with hundreds of sensors at a reduced cost. The problem arises when systems with thousands of sensors are needed. This work analyzes the implementation and performance of a virtual array with 6400 (80 × 80) MEMS microp...

BACKGROUND A problem with learning endotracheal intubation on airway mannequins is poor transfer of direct laryngoscopy skills from model to patient. We developed an airway model with adjustable anatomic features and investigated whether practicing on a model with frequent adjustments improved laryngoscopy skills transfer. METHODS Fifty-one paramedic students and 18 medical students with mini...

Introduction Rapid exposure of a trauma patient is an essential component of the primary survey. No gold standard exists regarding the best technique to remove clothing from a trauma patient. The purpose of this study is to compare two techniques of clothing removal versus usual practice using standard trauma shears. METHODS Advanced Care Paramedic (ACP) students were randomized to either the...

The influence of head position on thermal stress was assessed by using a heavily clothed thermal mannequin in three different body positions [supine, face straight up (FSU); supine, face to the side (FTS); prone, FTS] and with or without the head covered by a bonnet. The mannequin was exposed to air temperatures of 29, 32, 34, and 36 degrees C. When the head is uncovered, body or head position ...

BACKGROUND Surface topography is increasingly used with postural analysis. One system, DIERS formetric 4D, measures 40 defined spine shape parameters from a 6-s scan. Through system algorithms, a set of spine shape parameter values from 1 of 12 recorded images obtained during a scan becomes the DIERS-reported value (DRV) for postural assessment. The purpose of the current study was to compare D...

conclusions our results suggest that the personnel in the five participating faculties were highly satisfied with the practical performance of the residents, who were found to hold good attitudes towards the program as a whole. background the goal of this study was to evaluate the impact of intubation skill training involving the use of mannequins on novice anesthesiology residents in a knowled...

Observers recognize subtle changes in the movements of others with relative ease. However, tracking a walking human is computationally difficult, because the degree of articulation is high and scene changes can temporarily occlude parts of the moving figure. Here, we used functional magnetic resonance imaging to test the hypothesis that the superior temporal sulcus (STS) uses form cues to aid b...
