Abstract: A computer assisted facility monitoring method provides users with predefined operating procedures that are recommended for addressing one or more alarms acknowledged by the user. The predefined operating procedures are created and stored prior to the occurrence of the alarms. In some examples, after acknowledging an alarm occurrence, the user may be provided with an option for bypassing or disregarding the alarm, as some such acknowledgements may have been for false alarms. In some examples, the predefined operating procedure may specify multiple action steps for addressing an alarm. In such examples, the user can close out or settle an alarm incident even without completing all of the action steps, provided the user enters a valid reason for doing so. In some examples, a user can batch-select a group of alarms, wherein perhaps only some of the acknowledged alarms in the group have corresponding predefined operating procedures.

Abstract: Improvements to ice protection systems as disclosed herein include monitoring ice accretion intensity based on atmospheric conditions proximate to a vehicle. Examples of parameters that measure atmospheric conditions include a water content and a size distribution of an atmosphere around a vehicle. These parameters, along with other vehicle parameters, are used to control at least one ice protection element to reduce ice accretion intensity at one or more designated locations of the vehicle. Incorporating measurements of cloud conditions enables nuanced control of the ice protection system and improves overall system efficiency of the vehicle.

Abstract: A computer system provides a method for analyzing various parameters, variables and/or conditions associated with the operation of HVAC systems. Some example computer systems display a coordinate system with multiple graphs of variables and conditions having disparate units of measure, such as degrees Centigrade, percent, ppm, on/off, etc. In some examples, variables and conditions with similar units of measure are grouped together. The groups of similar units are plotted along different segments of the coordinate system's y-axis. The segments and their respective graphs of similar units are distributed vertically, one above the other. All of the graphs, however, share a common x-axis, which is labeled in units of time. This makes it easier to visually compare multiple, disparate variables and conditions at particular points in time. When an HVAC related problem occurs, the visual comparisons can help identify the problem and its source.
