Dry suit squeeze.
DESCRIPTION A 32-year-old scuba diver was admitted to the emergency department for distinct cutaneous lesions. Following an uneventful dive, his peers suspected of several lesions over his body pertaining to decompression sickness (DCS). After his initial assessment, he was referred to the underwater and hyperbaric medicine department for consultation. The patient was a senior diver and denied ...
متن کاملThe Effect of Standard Wave Conditions on Dry Suit Insulation When Measured on Humans
Testing of immersion suits is commonly conducted in calm or circulatory water. Several investigators have argued that this is an unrealistic test for a suit that is designed to protect a human from hypothermia in open ocean conditions. In support of this argument, Steinman et al. (1) and Romet et al.(2) reported a significant reduction of suit insulation in turbulent water when compared to stil...
متن کاملIn-Suit Sensor Systems for Characterizing Human-Space Suit Interaction
Although the U.S. has studied space suit performance for decades, relatively little is known about how the astronaut moves and interacts within the space suit. We propose the use of insuit sensor systems to characterize this interaction and present our results using pressure sensors and inertial measurement units (IMUs) inside the David Clark Mobility Mock-Up and the Mark III space suit from NA...
متن کاملTwo Different Squeeze Transformations
Lorentz boosts are squeeze transformations. While these transformations are similar to those in squeezed states of light, they are fundamentally different from both physical and mathematical points of view. The difference is illustrated in terms of two coupled harmonic oscillators, and in terms of the covariant harmonic oscillator formalism. The word “squeezed state” is relatively new and was d...
متن کاملSqueeze-and-Excitation Networks
Convolutional neural networks are built upon the convolution operation, which extracts informative features by fusing spatial and channel-wise information together within local receptive fields. In order to boost the representational power of a network, much existing work has shown the benefits of enhancing spatial encoding. In this work, we focus on channels and propose a novel architectural u...
