Provided is a method of a control device to set an alarm. The method includes: discovering a first control target device including an alarm service and a second target device including a content providing service; receiving a device list registered for the alarm service from the first target device; receiving available content information from the second target device; selecting an alarm target device and a content from the device list and the content information; and transmitting an alarm setting request message to the first target device on the basis of the selected alarm target device and content.

Control apparatus, control target apparatus, and alarm-setting method using the apparatuses

Provided are control device and a method of controlling a server. The method includes requesting an aggregated device list to the aggregate server; receiving the aggregated device list from the aggregate server; selecting at least one aggregated device from the received aggregated device list; requesting, to the aggregate server, content information collected from the selected aggregated device; and receiving, from the aggregate server, the content information of the selected aggregated device transmitted.

Control device, control target device and method of transmitting content information thereof

A wireless power transmitting device including a signal processing unit, a wireless transceiver, and a controller. The controller is configured to control a detection signal for detecting an external device to be transmitted via a wireless power transmitter, and if an authentication request signal is received from the external device in response to the detection signal, control an authentication response signal including an ID (Identification) assigned to the external device, and further, if a power profile signal including power amount information of the external terminal and change information indicating whether the power amount information is changed is received from the external terminal, control an allocation signal including wireless power allocation information indicating an allocated slot, determined based on the power amount information, to the external terminal.

The present invention relates to three-dimensional glasses, to a three-dimensional image display apparatus, and to a method for driving the three-dimensional glasses and the three-dimensional image display apparatus. The present invention is a method for driving three-dimensional glasses for watching a three-dimensional image consisting of a left-eye image and a right-eye image, wherein the method comprises the following steps: transmitting glasses characteristic information, including information relating to the opening/closing speed of shutters of a left-eye lens unit and a right-eye lens unit of the three-dimensional glasses, to an external three-dimensional image display apparatus for outputting the three-dimensional image; receiving synchronization information, including information relating to the output periods of the left-eye image and right-eye image, from the three-dimensional image display apparatus; and synchronizing, using the synchronization information, the opening/closing periods of the shutters of the left-eye lens unit and the right-eye lens unit with the output periods of the left-eye image and right-eye image outputted by the three-dimensional image display apparatus. The synchronization information includes information on the time of opening the shutter of the left-eye lens unit, information on the time of closing the shutter of the left-eye lens unit, and information on modes for indicating the type of image outputted by the three-dimensional image display apparatus, and the method for driving the three-dimensional glasses and three-dimensional image display apparatus of the present invention, efficient data communication between the three-dimensional glasses and the three-dimensional image display apparatus is enabled, in order to increase the convenience of a user watching the three-dimensional images and prevent the unnecessary consumption of a battery of the three-dimensional glasses.
