Abstract: A mobile terminal device includes: a memory that stores a restriction on a predetermined function or a release condition of the restriction as initial setting information; a determining unit that determines whether a condition of the setting information of the memory is satisfied; a generation unit that generates a restriction change request signal, which changes the initial setting information by a setting information change signal under a condition to change the initial setting information of the memory, and which requests the restriction on a function stored in the memory or the change of the release condition of the restriction when the determining unit determines that the condition of the changed setting information is satisfied; and a restriction release unit which, when detecting the restriction change request signal generated by the generation unit, performs the use restriction on the function or the restriction release based on the changed setting information.

Abstract: According to an aspect, a device includes: a display unit for displaying a screen; a sensor for detecting an inclination of the display unit; an operating unit for detecting an operation; and a controller. The controller changes an orientation of the screen depending upon the inclination detected through the sensor and the operation detected through the operation unit.

Abstract: According to an aspect, a communication device includes: a first communication unit for performing communication using a first communication scheme; a second communication unit for performing communication using a second communication scheme; and a control unit for processing the incoming call based on a status of the second communication unit.

Abstract: A telemeter system in which information that has an effect on a state of communication between a terminal device and a central device can be readily and accurately reported from the terminal device to the central device. When a central device (12) transmits a request signal for prescribed measurement result information to a terminal device (10), a terminal control component (20) of the terminal device (10) extracts the measurement result information from a measurement component (16), and transmits the measurement result information to the central device (12) via a telecommunication component (18) by using a short message service or the like. When a communication component (22) of the central device (12) receives the measurement result information, a center control component (26) stores the received measurement result information in a storage component (24) The state of communication between the terminal device (10) and the central device (12) is reported to an administrator as necessary.
