A Device for Human Ultrasonic Echolocation
Representing and interacting with the external world constitutes a major challenge for persons who are blind or visually impaired. Often, non-visual sensory modalities such as audition and somato-sensation acquire increased importance in sampling the environment. In many non-human species operating without vision, this is achieved by active echolocation, in which acoustic pulses are emitted and...
متن کاملUltrasonic hearing and echolocation in the earliest toothed whales.
The evolution of biosonar (production of high-frequency sound and reception of its echo) was a key innovation of toothed whales and dolphins (Odontoceti) that facilitated phylogenetic diversification and rise to ecological predominance. Yet exactly when high-frequency hearing first evolved in odontocete history remains a fundamental question in cetacean biology. Here, we show that archaic odont...
متن کاملMethylene Blue Based Device for Pathogen Reduction in Human Plasma
Abstract Background Despite improvement in safety of plasma transfusion some virus transmission still remains a problem. So as World Health Organization (WHO) recommends, many countries developed Pathogen Reduction Technologies (PRT) to inactivate pathogens, in plasma components. The Methylene Blue (MB) based methods is one of the most universal one. The purpose of this research was, produce...
متن کاملUltrasonic device for measuring periodontal attachment levels
Periodontal disease is manifested clinically by a degradation of the ligament that attaches the tooth to the bone. The most widely used diagnostic tool for assessment of periodontal diseases, measurement of periodontal attachment loss with a manual probe, may overestimate attachment loss by as much as 2 mm in untreated sites, while underestimating attachment loss by an even greater margin follo...
متن کاملCognitive Abilities in Human Echolocation
The human ability to echolocate differs between individuals. Blind perform significantly better then sighted. There is very limited research on psychological factors underlying this ability. This study is based on earlier research by Schenkman and Nilsson (2010). The research questions in the present study were whether blind individuals perform better then sighted on general cognitive tasks, if...
