BACKGROUND Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and correspondi...

The proposed system is a portable camera based visual assistance prototype for bind people to identify currency notes and also helps them to read printable texts from the handheld objects. To read printable texts, an efficient algorithm that combines an Optical Character Recognition (OCR) with Hierarchical optimization is used. In Pattern Recognition OCR every character is localized and separat...

he sequential sound therapy is a treatment of the tinnitus with white noise that has some own characteristics. They are described the methodology, as well as their differences and similarities with the Tinnitus Retraining Therapy. The sequential sound therapy has been carried out to seventeen patients assisted during the year 2002. 26 generators of sounds adapted, of them, 22 generators of soun...

A hear-through headset is formed by mounting miniature microphones on small insert earphones. This type of ear-wear technology enables the user to hear the sound sources and acoustics of the surroundings as close to real life as possible, with the additional feature that computer-generated audio signals can be superimposed via earphone reproduction. An important aspect of the hearthrough headse...

Nowadays, the use of 3D printing is becoming a key process for on-demand and customized manufacturing. One most flexible techniques fused deposition modeling (FDM), where combination multiple materials was recently introduced. A quantum leap in part design possible by integrating local variations between that allow expanded functionality to be built into single part. Therefore, co-extrusion mat...

One target of a ubiquitous computing environment is to aid users to get necessary information and services in a situation-dependent form. We have proposed a locationand orientation-based information support system using the Compact Battery-less Information Terminal (CoBIT). The CoBIT is a small, low cost communication terminal that works using only energy from the information carrier and the us...

INTRODUCTION One of the problems observed in pure-tone audiometry tonal has been the variation in test results of a same individual, particularly at frequencies of 4kHz, 6kHz and/or 8kHz. Improper placement of headphones is one of the factors that can cause alterations in results. OBJECTIVE To compare differences in auditory thresholds using earphones positioned by the examiner and by the wor...

Semiconductor System Lab, Dept. of EE, KAIST, Daejeon, Korea [email protected] Abstract—Low power on-body communication is introduced. The human body surface is examined for the communication channel and 10KHz-100MHz frequency band, ‘bodywire’, is found to be effective in the wireless on-body communication. DCI is proposed to avoid any intentional ground electrode for the capacitive coupling...
