  • Patent number: 8341703
    Abstract: In remotely coupling one terminal apparatus to a server apparatus, if an authentication processing of a user of one terminal apparatus has been already completed, the user can switch one terminal apparatus to another without an additional authentication processing. Authenticated information indicating that the authentication of the user has already been successfully completed is transferred to another terminal apparatus by coordinating the authenticated information between more than one terminal apparatuses. Another terminal apparatus receives a service from the server apparatus using the authenticated information. Upon coordinating the authenticated information among more than one terminal apparatuses, another terminal apparatus to receive the authenticated information may be authenticated. A storage medium which conducts the authentication may be coupled to a terminal apparatus to be authenticated.

  • Patent number: 7400319
    Abstract: A pair of piezoelectric substrates, the length of which is shorter than the length of one side in the longitudinal direction of the operation panel or the supporting board, is respectively fixed to one side from the diagonal position along the longitudinal direction. At the time of detecting an inputting operation, a drive voltage is applied and the entire operation panel or the supporting board is vibrated. Even when the four corners of the operation panel or the supporting board are supported by the housing for accommodating the tablet apparatus or supported by the display device so that the vibration of the four corners is restricted, since either of the pair of piezoelectric substrates, which becomes a vibration source, a feeling of inputting operation can be transmitted to an operator by the vibration, the amplitude of which is not less than a predetermined value, irrespective of the inputting operation position.
