  • Patent number: 10516325
    Abstract: Disclosed is a precise spatial motion device including: a motion unit including a plurality of drivers that do not contact each other and are elastically connected to each other; and a control unit that controls the drivers to drive in a six-degree-of-freedom manner and in three-dimensional space by controlling magnetic force. In accordance with the constructions of the present disclosure, the drivers are connected to each other in a non-contact and frictionless manner, and thus, driving may be performed in a six-degree-of-freedom manner and in three-dimensional space. Accordingly, position and attitude errors are not accumulated, whereby precise motion control may be achieved.

  • Publication number: 20140295385
    Abstract: Provided is a speed reading book for learning Chinese characters, which enables students to learn various Chinese characters while receiving speed reading training by writing figures in Chinese characters, the speed reading book including: study pages that include: a training element for the enlargement of a perceptible visual field; and an element for utilizing Chinese radicals. According to the speed reading book for learning Chinese characters of the invention described herein, since the students may repetitively perform training for seeing a Chinese radical which is the basis for studying Chinese and relevant Chinese characters whose radical is a Chinese radical in a lump, the students can have an enlarged visual perception field, can strengthen their concentration and reading ability, and can remember the Chinese characters for a long time because the Chinese radicals of the relevant Chinese characters are acquired as images through repetitive studying.
