The effect of alterations in the processing of proprioceptive signals, on postural control, has been studied using muscle vibration effects. However, reliability and agreement of muscle vibration have still to be addressed.This study aimed to assess intra- and interday reliability and agreement of vibration …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

In this paper we present the concept and initial design stages of the TaSST (Tactile Sleeve for Social Touch). The TaSST consists of a soft pressure-sensitive input layer, and an output layer containing vibration motors. A touch to ones own sleeve is felt as a vibration on the sleeve of another person. …

In this paper we investigate the expression of emotions through mediated touch. Participants used the Tactile Sleeve for Social Touch (TaSST), a wearable sleeve that consists of a pressure sensitive input layer, and a vibration motor output layer, to record a number of expressions of discrete emotions. …

In this paper we outline the design process of TaSST (Tactile Sleeve for Social Touch), a touch-sensitive vibrotactile arm sleeve. The TaSST was designed to enable two people to communicate different types of touches over a distance. The touch-sensitive surface of the sleeve consists of a grid of 4x3 …

Laboratory study using a repeated measures design. The aim of this study was to determine if ankle proprioception is targeted in exercises on unstable surfaces. Lateral ankle sprain (LAS) has recurrence rates over 70%, which are believed to be due to a reduced accuracy of proprioceptive signals from …

A high resolution infrared spectrum of species formed in a nitrogen-hydrogen plasma expansion was recorded. A cavity ring down detection scheme was used to record a rotationally resolved spectrum in the region from 3300 cm-1 to 3380 cm-1. Using the relative intensities and line positions it was determined …

Dit verslag beschrijft het ontwerpproces van een mechanische sensor die laagfrequente trillingen kan meten voor het reeds ontworpen Kolibriesysteem. Kolibrie is een trillingisolatiesysteem dat grondtrillingen over een grote bandbreedte kan reduceren met een factor van minimaal 100. De ontwerpopdracht …

In markten waar trillingen funest kunnen zijn voor productieprocessen of metingen is het belangrijk trillingen te kunnen isoleren. TNO heeft hiervoor Kolibrie bedacht. Dit verslag beslaat de verbetering op de sensor die in Kolibrie wordt gebruikt.

Introduction Nowadays, humans are used to sit a lot during daily activities. Most of the time this happens in a relaxed way. This position is also called ´slouching´ or ´slouched posture´. In the slouched posture the pelvis and the lumbar spine are flexed and places the muscle spindles, muscles and ligaments …
