Abstract: A house monitoring system includes at least one sensor that detects a predetermined event, a master device that communicates with the sensor, and is connected to a fixed telephone network so as to perform calls to other fixed telephones, and a mobile phone terminal that includes a display/input unit, performs wireless communication with the master device by using a wireless router, and is connected to other mobile phones via a mobile phone network. When the sensor detects the predetermined event, the master device transmits information regarding the sensor having detected the predetermined event to the mobile phone terminal, and the mobile phone terminal displays the information regarding the sensor having detected the predetermined event transmitted from the master device on the display/input unit.

Abstract: An alert mode designation unit that sets an alert state when a mobile phone terminal is not located inside a communication zone with a master device, and sets an alert release state when the mobile phone terminal is located inside the communication zone with the master device, and an alarm output unit that outputs an alarm if detection information from a sensor indicates an abnormal state when the alert state is set by the alert mode designation unit are included in the master device, and the alarm output unit does not output the alarm when the alert release state is set by the alert mode designation unit.

Abstract: In a monitoring camera system, a master device registers a smartphone and a wireless router therein in advance. If sensor detection information is received from a human sensor, the master device requests a monitoring camera to transmit image/audio data, and sends image/audio data transmitted from the monitoring camera to the smartphone via the wireless router. The smartphone displays the image data sent from the monitoring camera on a touch panel.

Abstract: A monitoring system includes a sensor, a monitoring camera, a power control apparatus, a master device that is connected to a fixed telephone network so as to perform calls to other fixed telephones, and a mobile phone terminal that is connected to other mobile phones via a mobile phone network. When an abnormality is detected, the sensor, the monitoring camera, or the power control apparatus transmits an abnormality detection signal to the master device. When the abnormality detection signal is received, the master device converts at least a part of the abnormality detection signal so as to generate notification information, and transmits the notification information to the mobile phone terminal. The mobile phone terminal displays a warning screen based on the notification information on the display unit.

Abstract: A telephone set, where the state of an own-telephone-set is on-hook, the off-hook state of a parallel-telephone-set is detected by comparing telephone-line voltage value with a first standard voltage value. In the state where the own-telephone-set is off-hook, the off-hook state of the parallel-telephone-set is detected by the following method, i.e., the telephone-line voltage value is measured in detail and a second standard voltage value for judging the off-hook state of the parallel-telephone-set is determined and the voltage value is stored in place of the first standard voltage value while the own-telephone-set is off-hooked, then if the line voltage value exceeds the second standard voltage value, the parallel-telephone-set is regarded as off-hook.

Abstract: A telephone apparatus can receive information about a third party sent from a telephone exchange with a call waiting service when a call is issued from the third party during a conversation using the telephone apparatus. Upon issuance of the call from the third party during the conversation over the telephone apparatus, the exchange sends out an alert signal, in response to which the telephone apparatus sends back an acknowledge signal. The telephone apparatus also mutes a speech transmitter circuit in order to protect calling party information such as a telephone number sent from the exchange in succession from being destroyed by a speech signal. The calling party information sent from the exchange can be received without fail and can subsequently be displayed.

Abstract: A telephone set includes a detector for detecting telephone number data coming from a telephone line, a store device for storing the telephone number data detected by the telephone number detector, and an editing unit for editing the telephone number data stored in the store device. The telephone set also includes a display for indicating the telephone number data edited by the editing unit, and a dial signal transmitter for generating a dial signal corresponding to the telephone number data edited by the editing unit, and for transmitting the dial signal to the telephone line.
