Abstract: A system for tracking usage patterns of electrical appliances is disclosed. The system comprises a central database configured to receive and store information; a plurality of energy sensors each of the plurality of sensors being configured to measure a change in electrical energy use by a corresponding one of a plurality of electrical appliances; at least one presence sensor configured to determine when at least one user is proximate to the plurality of electrical appliances and send presence information to the central database; and a processor configured to extract features from such information and create at least one user profile corresponding to the at least one user and a pattern of electrical energy use associated with the at least one user based on said features.

Abstract: A method for decomposing Electro-Derma Activity signals from a user to infer response to content commences by first high-pass filtering the raw EDA signals collected from a user to reduce the influence of tonic signals. The high-pass filtered EDA signals are then fitted to a dictionary of feasible skin conductance response signals.

Abstract: A method for determining user responses to content commences by collecting Electro-Dermal Activity (EDA) signals from a user via a collection system as the user consumes (e.g., views) the content. From the collected EDA signals, the amplitudes of the users' responses are extracted at particular times. The extracted amplitudes undergo processing with demographic information for the user and parameters of the collection system obtained during training to predict feedback of the user to the content.

Abstract: A method, apparatus and system for determining viewer reaction to content elements include generating a viewer feedback signal by recording biometric measurements of a viewer's reactions to viewed content, synchronizing the viewer feedback signal with a content metadata signal for the viewed content and correlating the biometric measurements in the viewer feedback signal with respective elements in the content metadata signal to determine a viewer reaction score for the respective elements in the content.

Abstract: The invention relates to a method of detecting an anomaly in traffic containing a plurality of flows. Each flow has a plurality of flow features. The method including the steps of: (i) dividing the traffic into a plurality of sets, on the basis a first flow feature, such that the flows in at least one of the sets have a common value for the first flow feature (ii) determining that the anomaly is present in one of the sets and, (iii) dividing the set in which the anomaly is present on the basis of a second flow feature, such that the flows in at least one of the resulting sets have a common value for the second flow feature.
