Abstract: A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.

Abstract: Techniques and systems are provided for processing user interface content. For example, a server computer can receive a user interface event corresponding to a user interface of a device (e.g., a client device, another server computer, or other device). An application associated with the user interface event can be determined, and an interface model 5 can be generated using the application associated with the user interface event. The interface model defines state information for one or more graphic objects of the user interface. The state information results from the user interface event. The server computer can send the interface model to the device, which enables the device to render the user interface.

Abstract: Example embodiments provide systems and methods for managing intelligent content queuing from a secondary device for content delivery to a primary device. A content queuing system on the secondary device generates and displays a playlist interface on the secondary device. A selection of a content item to be added to a playlist is received. The content queuing system determines that addition of the content item causes a live content item to overlap with an on-demand content item on the playlist. As a result, the content queuing system creates at least two segments for the on-demand content item. The live content item is positioned between the first and a second segment on the playlist. The first segment is scheduled to end at a start time of the live content item and the second segment is scheduled to begin at an ending time of the live content item.

Abstract: Methods, system and devices are provided that generate a sequence of sub-keys for cryptographic operations from a main key. The main key is operated on only once to generate the sub-keys of the sequence, with a transformation comprising one or more one-way functions. The respective bit values of the sub-keys of the sequence are set using respective bit values of the one or more one-way functions. Advantageously, deriving sub-key bits from respective output bits of one or more one-way functions removes or at least reduces correlations between the main key and the sub-keys, as well as between sub-keys, making it harder or even impossible to recover the main key or other sub-keys from a single sub-key, for example as found using a side-channel attack.
