Abstract: A computer-implemented system and method for integrating user observations into operational data is provided. A database maintains notes each having received from a user and comprising a subjective observation. Operational data including workflow data of an objective nature is defined. Each of the notes is associated with one or more tags. The note associated with the tags is further maintained in the database. Criteria for retrieving the note are defined for the workflow data and forming a query for each of the workflow data. The query to select the note associated with the tags is executed for the workflow data based on the criteria and the selected note is integrated into the workflow data. The workflow data with the integrated note is displayed on a display.

Abstract: An automated abnormal machine tracking and notifying method includes automatically collecting and analyzing a plurality of test results to obtain a plurality of abnormal information, storing the abnormal information in a machine status database, respectively counting an integral value of each abnormal information of at least a related potentially abnormal machine, judging whether a sum of the integral values of each potentially abnormal machine is greater than n, and automatically notifying at least a user of the potentially abnormal machine and the abnormal information by an automatic notification subsystem when the sum of the integral values is greater than n.

Abstract: A heat exchanging ventilator comprises a temperature isolating body including an air admitting passageway and an air venting passageway couplingly arranged therein and allowing to conduct heat with each other. The two ends of the air admitting and venting passageways are in communication with the indoors and outdoors, respectively, and the air admitting and venting passageways are provided at inlets thereof with suction fans, individually, so as to let fresh air to be sucked from the suction fan of the air admitting passageway, while the indoor air may be vented from the suction fan of the air venting passageway, thereby exchanging air. Likewise, by means of the heat conductivity of the air admitting and venting passageways with each other, the indoor air temperature inputted from the air admitting passageway is approximately equivalent to room temperature.
