  • Patent number: 10827080
    Abstract: An electronic apparatus is configured to generate a variety of vibrations corresponding to a variety of different situations without excessively high power consumption. The electronic apparatus has first and second vibration motors having respective eccentric weights different in weight from each other for generating different first and second vibrations. An input/output section enables a user to select from a list of events stored in a storage section first events and second events. A controller drives the first vibration motor having a heavier weight with a strong vibration upon occurrence of the user-selected first events and drives the second vibration motor having a lighter weight with a weak vibration upon occurrence of the user-selected second events. The first events include an incoming phone call or email, a present alarm time, and a dynamic or important action, motion, and so on in a computer game.

  • Patent number: 10745959
    Abstract: In a touch sensor unit, a bracket body is provided with a first protruding portion which is disposed on a vehicle interior side of a base portion, a gap portion is provided between the first protruding portion and the base portion, the height from the bracket body to the distal end of the first protruding portion is smaller than the height from the bracket body to the sensor portion. Therefore, when the sensor portion and the base portion are elastically deformed by contact with a blockage, the elastically deformed sensor portion and base portion enter the gap portion, thereby preventing the sensor portion and the base portion from being pressed against the corner portion of the bracket without increasing the rigidity of the sensor portion and the base portion.
