Abstract: A dialog understanding device includes a sound collection module configured to collect a sound signal, a contextual processing module, and a dialog system configured to perform a dialog with a human. The contextual processing module includes a plurality of layers for processing information obtained from the sound collection module. A fallback processing module of a case where a predetermined process has not succeeded for the collected sound signal is provided on each layer of the plurality of layers. A process of the next layer is performed after a fallback corresponding to a fallback process performed by the fallback processing module is performed. A sound signal obtained when the contextual processing module completes a process is input to the dialog system.

Abstract: A wall panel system. In an embodiment, the wall panel system includes a plurality of wall panels magnetically and removably mounted to magnetically attractive mounting brackets affixed to a wall. In an embodiment, the mounting brackets are steel strips mounted at selected heights above the bottom of the wall. The wall panels may include various design components, including wood, wood veneer, textiles, metal, dry erase board, chalkboards, tempered glass, artistic paintings and designs, as well as functional components such as lighting panels or bookcases. A plurality of permanent magnets is affixed to a backing plate, preferably in a recessed configuration with respect to a reverse surface of the backing plate. The magnets releasably secure the wall panels to the mounting strips.
