Abstract: The present disclosure provides a computer-implemented method of graphically representing events relating to a plurality of users. The method comprises: graphically representing a knowledge base, the knowledge base comprising concepts that are linked by relations; receiving a plurality of interim graphs each relating to an event, said interim graphs each comprising a plurality of nodes including a node identifying the user associated with the event and a node identifying a concept describing an outcome of the event; linking the plurality of interim graphs with the knowledge base to form a relation between the nodes in the interim graphs identifying the concepts and corresponding concepts in the knowledge base to produce a graphical representation of a user profile including the knowledge base augmented with the interim graphs relating to a plurality of users.

Abstract: The present disclosure provides a computer-implemented method of building a user profile for a medical diagnostic system. The method includes receiving a new event including data describing a consultation with the user from a conversation module of the diagnostic system. The method also includes encoding the new event using JavaScript Object Notation (JSON). The method also includes storing the encoded new event in a queue of events. The method also includes decoding and translating the new event into a form compatible with the user profile. The method also includes adding the translated new event to the user profile.

Abstract: A method and apparatus are described for controlling the flow of power in each input line to a three phase AC inductive load in order to reduce the amount of VAR in the system, and thus increase the operational efficiency of the inductive load. Solid state relays are positioned in series in each of the three inductive load line inputs, and current allowed to flow to the inductive load only during the time during which the SSRs are in a conducting state. The calculation of VAR is achieved by processing data from each of the input lines using a separate controller boards each dedicated to each of the lines. The controller in turn, based on the calculated VAR, increments the time, either increasing or decreasing it from a predetermined value, during which the SSRs in that line remains in the non-conducting state.
