As one part of the decommission tasks of Fukushima nuclear power plant, efficient and appropriate operation of removal of fuel debris requires essential information of distribution and characteristics of fuel debris. A robotic remote measurement system using an ultrasonic sensor called RhinoUS was developed to detect the distribution of the fuel debris and localize the unknown water leakages in the primary containment vessels (PCV) of the No.1 reactor. Experiments are carried out to evaluate the localization accuracy on the robot pose of the visual odometry method.

Figures are an essential part of scientific literature, but students with severe print disabilities do not presently have good access to figures. Most figures are “made accessible” by a written or audio description. Tactile representations can make figures accessible, but tactile figures must have braille labels, but relatively few blind people read braille and only a small percentage of blind braille readers can read tactile graphics. Figures are potentially very accessible to a wide variety of students with print disabilities through a combination of tactile and audio description, but audio-tactile technology has been labor-intensive and often difficult to use. A new version of the ViewPlus IVEO audio/touch technology could be a major step in the evolution of audio/touch toward a future in which figures can be universally accessible to everybody. The audio/touch method and the improvements being introduced in the new IVEO version are discussed in this paper.
