3d Shape Measuring Instruments Using High Stiffness Vibration Touch Sensor

In this paper, a novel method to determine the shape of a 3D object is proposed. Instead of a flexible conventional touch probe, a high-stiffness vibration touch sensor was developed. The proposed sensor consisted of a piezo-electric device and thin probe, and generated feedback voltage according to the relative distance from the object. The structure of this sensor is simple, so that it can wi...

TIMED Instruments

he Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) mission is providing a core set of measurements defi ning the basic states of the mesosphere and lower thermosphere/ionosphere (MLTI) region (approximately 60–180 km above the Earth’s surface) and its global energy balance. This article discusses the TIMED spacecraft’s suite of four remote sensing instruments designed to ob...

Diagnostic instruments

As a psychological and medical journal, GMS Psycho-Social-Medicine places a high premium on the study of the behavioural, medical and social mechanisms that determine health, well-being and illness across the life span. GMS Psycho-Social-Medicine maintains also a vivid interest in the development and refinement of psychometric instrumentation for measuring psychological constructs. This special...

Temperature and vibration thresholds in vibration syndrome.

In a study to investigate whether the quantitative assessment of temperature and vibration thresholds can improve the evaluation of the neurological symptoms in vibration syndrome 37 patients with neurological symptoms (paraesthesias, numbness, pain) in the hands who had worked with hand held vibrating tools and 46 healthy controls not exposed to vibration were examined. Temperature thresholds ...
