Patent number: 5086452Abstract: A mobile unit is normally disposed in a predetermined positional relationship with a base unit connected to a wired line. For example, the mobile unit is mounted on the mobile-unit receiving part of the base unit. If the predetermined positional relationship is changed, it is detected by means of a detector such as a electrical, mechanical, or optical detector. In response to the detection of a change in the predetermined positional relationship, a radio link may be established between the base unit and the mobile unit or a communication link may be established between the mobile unit and a calling party. Furthermore, in response to the detection of the change, the mobile unit or the base unit may be partly or entirely powered so as to establish the radio link or the communication link. When the mobile unit is reset to a position in the predetermined positional relationship, it is detected by the detector.Type: GrantFiled: June 9, 1989Date of Patent: February 4, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Koichi Ito, Masanori Toba
