assessment of a simple obstacle Detection Device for the visually impaired
Applied Ergonomics, 2014Co-Authors: Chenglung Lee, Chihyung Chen, Pengcheng Sung, Shihyi LuAbstract:Abstract A simple obstacle Detection Device, based upon an automobile parking sensor, was assessed as a mobility aid for the visually impaired. A questionnaire survey for mobility needs was performed at the start of this study. After the detector was developed, five blindfolded sighted and 15 visually impaired participants were invited to conduct travel experiments under three test conditions: (1) using a white cane only, (2) using the obstacle detector only and (3) using both Devices. A post-experiment interview regarding the usefulness of the obstacle detector for the visually impaired participants was performed. The results showed that the obstacle detector could augment mobility performance with the white cane. The obstacle Detection Device should be used in conjunction with the white cane to achieve the best mobility speed and body protection.

arc fault Detection Device s test circuit
2016Co-Authors: Shi Huidong, Pan Dongqiang, Fu HuaAbstract:The utility model discloses an arc fault Detection Device's test Device, include: power, first testing switch group, arc fault Detection Device, first load interface, second load interface, second testing switch group and arc fault test Device. Arc fault Detection Device inserts the power, and its output is connected to the phase line and the neutral conductor. The cross -over connection of first load interface inserts shielding load and/or resistive load between the phase line and the neutral conductor. Second load interface concatenates on the neutral conductor, inserts the experimental current level of resistive load in order to adjust test circuit, perhaps inserts shielding load and/or resistive load. The cross -over connection of second testing switch group perhaps concatenates in the central line between the phase line and the neutral conductor. Arc fault test Device connects between phase line and central line. The utility model discloses still revea above -mentioned arc fault Detection Device's test Device, used same test Device to accomplish the experiment of series connection arc fault, shielding experiment and mistake trip -gear.
