One of the objectives of the European SUBZERO project was to study the influence of sweat evaporation and condensation on the heat transmission properties of cold protective clothing. With the sweating thermal manikin Coppelius, water vapour transfer through and water condensation in the clothing can be determined simultaneously with the thermal insulation. In this study, 4 cold protective ense...

Manikins are essential in teaching and practicing CPR. Industry as provided them in different degrees of complexity. Costs are irectly proportional to sophistication and in some cases it might e a limiting factor especially among poor people. Training programs in emergencies have been developed for umble populations, and have included the use of a CPR dummy ade with simple materials – in compar...

Presenting sounds to humans in virtual environments requires convolving the free field signals with a head related transfer function (HRTF), which is a frequency response describing the filtering effects of the pinna, head and torso of a human. Sets of HRTFs are usually measured on the dummy head or human subjects at different directions in an anechoic room. This paper describes the details of ...

Parachute opening shock tests were conducted with an instrumented test manikin to measure and record transmitted neck loads. The standard paratrooper helmet, as well as two developmental helmet systems, were fitted to the manikin head. These two systems alter the headborne weight and center of mass from the standard helmet, potentially increasing the risk of acute neck injury during parachute o...

In the background of COVID-19, new requirements are occurring in novel ventilation systems to mitigate airborne transmission risk indoor environments. this study, two micro-environment systems: personalized combined with radiant panel system (PVRP) and low velocity unit (LVRP) were studied explore potential reducing infection risk. a simulated double layout office, droplets generated by thermal...

A comparison of the I-gel supraglottic airway as a conduit for tracheal intubation with the intubating laryngeal mask airway: A manikin study.

Echo-doppler examination of the jugular vessel is a powerful tool for early diagnosis cardiovascular disorders that can be further related to central nervous system diseases. Unfortunately, ultrasound technique strongly operator-dependent, so quality scan, accuracy measurement, and therefore rapidity robustness reflect degree training. The paper presents development mechatronic simulation impro...
