Abstract: A server apparatus includes a terminal-side receiver for receiving, via a first network, information including appliance information that identifies an electric appliance, from a terminal apparatus operable by a user, an appliance-side receiver for receiving, via a second network, information including an identifier of the electric appliance and information about a state of the electric appliance, and a storage unit that stores the appliance information received by the terminal-side receiver and the identifier of the electric appliance, for which it is judged, from the information about the state of the electric appliance received by the appliance-side receiver, that the appliance state has been changed, in association with each other, upon reception of trigger information by the terminal-side receiver.

Abstract: A household electric appliance is operated with alternating current power. The household electric appliance is operated also with direct current power. A communication terminal displays a screen by execution of a power management application of a power management system including the household electric appliance. A graph of the screen indicates power consumption of each day for one month, more specifically, indicates consumption of direct current power supplied from a direct current power source to the household electric appliance together with consumption of alternating current power supplied from an alternating current power source thereto.

Abstract: The present invention aims to provide a method by which a user recognizes that firmware of a control device related to a remote monitoring system is being updated. In a remote monitoring system including a mobile terminal operated by a user, a server that communicates with the mobile terminal, and the control device that communicates with the server, the mobile terminal communicates with the control device through the server, and the server knows start and completion of an update of firmware of the control device by communicating with the control device. In a case where an operating instruction to the control device is issued from the mobile terminal while the firmware of the control device is being updated, the server notifies the mobile terminal that the firmware of the control device is being updated.

Abstract: A communication system includes: a server apparatus; and a terminal apparatus that becomes capable of accessing the server apparatus through authentication based on information for identifying a user, wherein upon receiving an input of first identification information after the authentication, the terminal apparatus sends the first identification information to the server apparatus via a first communication line, the server apparatus receives second identification information sent from an electronic apparatus via a second communication line, the second identification information being unique to the electronic apparatus, upon receiving the first identification information and the second identification information, the server apparatus determines whether the first identification information matches part of the second identification information, and if the first identification information matches the part of the second identification information, the server apparatus registers the electronic apparatus in associa

Abstract: Provided is a network system including at least first and second communication terminals capable of communicating with each other via a network. The first communication terminal causes handwritten data input in response to an instruction for a point on an image to be displayed in a certain position on the image corresponding to this point, associates the point information about the point with the handwritten data and transmits the point information and the handwritten data to the second communication terminal. Based on the point information and the handwritten data from the first communication terminal, the second communication terminal causes at least a part of the image to be displayed on a second display and also causes the handwritten data to be displayed in a location in accordance with the point information.

Abstract: A communication terminal includes a touch panel, a communication device for communicating with an other communication terminal, and a processor for reproducing contents using a touch panel, temporarily stopping reproduction of the contents and transmitting a stop instruction to the other communication terminal according to a first input, resuming the reproduction of the contents and transmitting the resumption instruction to the other communication terminal according to a second input, temporarily stopping the reproduction of the contents according to a stop instruction from the other communication terminal, and resuming the reproduction of the contents according to a resumption instruction from the other communication terminal.

Abstract: A first communication terminal includes a first communication device, a first touch panel for displaying motion picture contents, and a first processor for accepting input of a hand-drawing image. The first processor transmits a hand-drawing image input during display of the motion picture contents and start information for identifying a point of time when input of the hand-drawing image at the motion picture contents is started to a second communication terminal. The second communication terminal includes a second touch panel for displaying motion picture contents, a second communication device for receiving the hand-drawing image and start information from the first communication terminal, and a second processor for displaying the hand-drawing image from the point of time when input of the hand-drawing image at the motion picture contents is started on the second touch panel, based on the start information.
