This includes a motion analysis method for upper limbs, a non-invasive optical blood glucose measurement technique using near-infrared radiation, image fusion of multimodal cardiac images, functional electrical stimulation for the restoration and rehabilitation of motor function, medical manipulators for surgical applications, a walking assistance robot, a wearable power assist robot driven with pneumatic rubber artificial muscles, automated analysis of nursery school observations, a sleep monitoring system, quantitative modeling of neuronal polarization, and a web-based image database system.
The team tested their handiwork by illuminating polished and roughened versions of the material with near-infrared radiation at a wavelength of around 900 nanometres, just beyond the red end of the visible spectrum.
For example, Tiina Karu, PhD, showed that respiratory chain molecules (such as cytochrome c oxidase) in the mitochondria absorb visible and near-infrared radiation.
The first glimmers came from observations of radio waves and X rays, which easily pass through dust, and studies of near-infrared radiation, which can penetrate dust 10 times better than visible-light can.
Over the past two years, as they were developing the detector, Gore, research scientist Yudaya Sivathanu, and their graduate students examined the near-infrared radiation given off by several types of fires covering a wide range of combustible materials.
However, intensive use of glass glazing can cause harsh lighting effects and lead to interior heat buildup from penetration of near-infrared radiation, especially in hot and/or sunny locales.
The tubes, when non-invasively exposed to laser-generated near-infrared radiation, respond by vibrating, creating heat.
Because of its large size, the camera can detect near-infrared radiation from a given region of the sky more than 50 times faster than the detector that McMahon and Hu used at Keck I.
