Selective call receiver with motion detector

Abstract

A wireless selective-call receiver makes use of detection or absence of any to-and-fro movement of the receiver indicating that the receiver has been left somewhere thereby improving the security function of the receiver. When a motion detector detects no continuous shaky movement of the receiver, the message received by the receiver is stored in memory. A controller comprises a first control section which operates in a no movement condition, a second control section which operates in a moving condition, and a switching means for switching from the first control section to the second control section and vice versa. In the absence of the to-and-fro movement of the receiver (for example, the receiver is put away from the owner's body to be left on the desk), any access through a button inputting console and external interface except inputting a password is rejected. The message received is stored in memory, and not given on display, thereby preventing pieces of private information from leaking. In the absence of the shaky movement of the receiver the sound-making section alarms a sound at regular intervals, and an emergency contact address or telephone number is exhibited on display. Thus, the receiver once lost can be returned to the owner easily while maintaining security of information stored in the memory.
