  • Publication number: 20200272242
    Abstract: In an electronic information processing system, a brain activity detection unit detects an activity of a user's brain. A change determination part determines whether a character input mode presently set needs to be changed to a different character input mode based on a detection result of the brain activity detection unit after a character input under the character input mode presently set is displayed on a display unit. When the change determination part determines that the character input mode presently set needs to be changed to the different character input mode, the character input mode setting part sets the different character input mode instead of the character input mode presently set.

  • Patent number: 10525508
    Abstract: The present invention has an object to provide a blowing apparatus wherein a piezoelectric element is unlikely to cause insulation deterioration leading to burnout during use of the blowing apparatus. The blowing apparatus of the present invention blows compressed gas supplied from a compressed gas supply unit through a nozzle hole of a nozzle unit by opening a piezoelectric valve. The blowing apparatus comprises a humidity sensor detecting a humidity of the compressed gas inside a flow path unit, and a humidity control unit comparing a detected value of the humidity detected by the humidity sensor with a set value. If the humidity of the compressed gas inside the flow path unit detected by the humidity sensor is equal to or greater than the set value, the humidity control unit replaces the compressed gas inside the flow path unit with the compressed gas whose humidity is less than the set value and which is supplied from the compressed gas supply unit, before starting to use the blowing apparatus.
