Abstract: A system for monitoring usage of an electrical appliance includes an electrical socket device and a server. The electrical socket device includes an audio receiving module for generating an audio result based on sound at a site where the electrical appliance is disposed, and a processing module configured to generate audio feature data based on the audio result and to generate event data that is related to the usage of the electrical appliance at least based on the audio feature data. The server stores a behavioral feature recognition model that is configured to recognize multiple behavioral features related to behaviors of the user using the electrical appliance. The server uses the behavioral feature recognition model to determine whether the event data matches one of the behavioral feature, and sends a warning message to a user end device when the event data does not match any of the behavioral features.

Abstract: A site monitoring method uses an electrical socket device to collect current data of an electrical appliance that is electrically connected to the electrical socket device. Based on the current data, a management server can derive a user behavior in connection with using the electrical appliance, and send out a warning message when the user behavior thus derived is abnormal.

Abstract: A stereoscopic system includes: a storage device; an image transforming module coupled to the storage device to receive therefrom image frame data of correlated first and second image sequences that are acquired from a source video stream, and configured to apply at least one of geometric distortion and geometric tilt processes to the image frame data of at least one of the first and second image sequences for outputting image frame data of corresponding first and second intermediate image sequences; a stereoscopic image sequence generating module coupled to the image transforming module for receiving the image frame data of the first and second intermediate image sequences therefrom, and configured to process the image frame data for obtaining image frame data of a stereoscopic image sequence; and a stereoscopic viewing device coupled to the stereoscopic image sequence generating module for enabling viewing of the stereoscopic image sequence by a user.
