Abstract: A data fusion based safety surveillances system has a first through Nth virtual monitoring systems and a data fusion and decision device. The data fusion and decision device defines an ith detection model of the ith virtual monitoring system, and estimates an ith detection loss probability of the ith virtual monitoring system according to detection loss sample numbers of batches of ith monitored data of the ith virtual monitoring system under conditions corresponding to the locations, batches of context data and existence of intruder, the ith detection model, the batches of ith monitored data corresponding to locations of the ith virtual monitoring system and the batches of context data. The data fusion and decision device determines a fusion parameter set according to the first through Nth detection loss probabilities, and performs data fusion on a first through Nth detection results to generate a decision result.

Abstract: A process context-awareness method analyzes events arising from a process according to context concepts, compare and analyze entity contents of the events, event types, applicable contextual situations and rules, so as to subsequently trigger the other activities or yield result. The method applies to enterprise information systems, project scheme execution or meets any other operation requirement, suits different enterprise operational context, gains insight into dynamic circumstances of the enterprise context.

Abstract: A process context-awareness method analyzes events arising from a process according to context concepts, compare and analyze entity contents of the events, event types, applicable contextual situations and rules, so as to subsequently trigger the other activities or yield result. The method applies to enterprise information systems, project scheme execution or meets any other operation requirement, suits different enterprise operational context, gains insight into dynamic circumstances of the enterprise context to thereby identify flexible solutions thereto. Hence, process information systems created with the method save manpower, time and costs otherwise incurred in constructing customized systems for use by different tenants and enhance the system maintainability.

Abstract: A method of establishing a process operational framework in accordance with a context concept is introduced. The method involves establishing a process operational framework in accordance with a context concept in a manner that the process operational framework thus established applies to the process-oriented streamlining of an enterprise information system, project execution, and the other working needs. The method is flexible and adaptive to different enterprise operation context in terms of working, reduces the time and financial resources spent on customizing systems for use by different customers, and enhances the ease of maintenance of the enterprise process management system.

Abstract: A smell producing and outputting device capable of providing a certain smell correspondingly to a certain image or a certain sound is disclosed. The disclosed smell producing and outputting device comprises: an audio processing unit for detecting an image signal or a sound signal; and a smell producing and outputting unit including a smell storing reservoir, a compression part, a driving part, and an outside shell, wherein the smell storing reservoir, the compression part, the driving part are received by the outside shell, and the driving part is electrically connected with the audio processing unit. When a certain image signal or a certain sound signal is received by the audio processing unit, the audio processing unit outputs a driving signal to the driving part, for changing the position of the compression part. Thus, a smell is driven out from the smell producing and outputting unit and distributed in the atmosphere.
