摘要: A program for light commercial building system (LCBS) solutions. Solutions and other systems may incorporate lightweight alerting service, auto-adjustment of gateway poll rates based on the needs of various consuming applications, detecting loss of space comfort control in a heating, ventilation and air conditioning (HVAC) system, HVAC capacity loss alerting using relative degree days and accumulated stage run time with operational equivalency checks, and HVAC alerting for loss of heat or cool capacity using delta temperature and dependent system properties. Also, incorporated may be triggering s subset of analytics by automatically inferring HVAC equipment details from controller configuration details, ensuring reliability of analytics by retaining logical continuity of HVAC equipment operational data even when controllers and other parts of the system are replaced, and an LCBS gateway with workflow and mechanisms to associate to a contractor account.

摘要: A monitoring method, the purpose of which is, when a loss of power is detected in an aircraft engine, to generate an alarm in the form of a single message displayed on a display screen in the cockpit, in order to indicate if the level of damage suffered by the engine is critical or not. The steps implemented are based on alarm signals transmitted by a central processing unit of the engine and also on alarm signals transmitted by a diagnostic device for the onboard systems of the aircraft, in order to take account of both the situation of the engine and also the situation of the systems surrounding the engine which can be affected by damage to an engine.

摘要: Examples of techniques for monitoring a component used in well operation are disclosed. In one example implementation according to aspects of the present disclosure, a method may include: receiving, by a processing system, sensor data from a sensor, wherein the sensor collects data relating to a component used in the well operation; analyzing, by the processing system, the sensor data to determine whether the component used in the well operation is experiencing an error condition; and alerting, by the processing system, a user of the error condition when it is determined that the component used in the well operation is experiencing an error condition.

摘要: A system, method, and an apparatus relating to data collection regarding valve movement over a period of time in order to determine the effects of stiction on the valve. With data collection done over a period of time, it is possible to remove dependency on a high speed method of data collection. The evaluation of the valve movement includes consideration of a manipulated variable (MV) for diagnosis, or detection, of stiction of the valve.

摘要: Various embodiments of the present invention provide systems and methods for managing fault codes triggered by one or more vehicles during operation. In general, various embodiments of the invention involve recording and analyzing fault codes triggered during a particular time period while a vehicle is in operation. As a result of the analysis, various embodiments of the invention may set a state for each of the identified fault codes, the state indicating a level of action to address the identified fault code. In particular embodiments, the states may be one of a caution state indicating one or more components or sub-systems of the vehicle should be monitored, a critical state indicating one or more components or sub-systems of the vehicle should be repaired, or an environmental state indicating failure or potential failure of one or more components or sub-systems of the vehicle may affect one or more environmental conditions.

摘要: The metal tank portion of an electric water heater is protected against corrosion utilizing a corrosion protection system that detects a voltage potential between the sheath portion of a tank water-immersed electric heating element and the tank. In one embodiment of the corrosion protection system the sensed sheath/tank potential is utilized to enable a user of the water heater to accurately gauge the necessity of replacing a sacrificial anode extending into the tank. In another corrosion protection system, the sensed sheath/tank potential is utilized to provide impressed current cathodic protection of the tank and also to prevent dry firing of the electric water heater.
