  • Publication number: 20170039873
    Abstract: A method may include estimating a current level of vocabulary knowledge of a learner. The method may also include determining a first vocabulary level of a first chunk in an electronic document read by the learner. Additionally, the method may include comparing the current level of vocabulary knowledge of the learner with the first vocabulary level of the first chunk. The method may further include determining whether to replace, in the electronic document, the first chunk with a second chunk of a vocabulary database based on the comparison of the current level with the first vocabulary level. The second chunk may have a second vocabulary level.

  • Patent number: 9551835
    Abstract: A GRIN lens array of an embodiment has a structure for enabling a coupling face in which lens end faces of GRIN lenses are arranged, to be accurately polished so as to have a desired angle relative to optical axes of the GRIN lenses. The GRIN lens array has the GRIN lenses and a main body portion. The main body portion comprises a holding portion having a coupling face, and an edge portion having a reference face to be used as a reference in polishing of the coupling face. The respective thicknesses of the holding portion and the edge portion along the longitudinal direction of the GRIN lenses are set so as to form a step between the coupling face and the reference face.
