摘要:
A braille teaching device presents a planar base with opposed writing and reading surfaces. A plurality of cells in the base comprises an array of six bores corresponding to the location of potential embossed dots in the braille matrix. Dowels in each bore have writing and reading ends. To simulate the writing of a braille character selected dowels in each cell are plunged through the bores until the writing end of each dowel is positioned flush with the writing surface. Upon presenting the reading surface to the user, the user can read the previously written braille character by tactilely sensing the reading ends of each previously plunged dowel as displaced from the reading surface.
摘要:
Compositions of a mixture of a thiol material and a material that contains a reactive unsaturated carbon-carbon bond that can be polymerized to form a charge-transporting or luminescent film are described, as is an organic light-emitting diode (OLED) device comprising at least one such charge-transporting or emissive layer that has been formed by polymerizing a thiol material and an ene material. The process for forming such an OLED, including the deposition of a layer of material comprising the polymerizable composition, from solution, exposing said layer to actinic radiation through a mask, and then optionally developing said film to form a photopatterned film, is also disclosed.
