摘要:
In an energy efficient building, a thermostatic controller receives temperature and humidity input signals indicative of an inside, outside and air mass buffer. According to one or more algorithms, the thermostatic controller controls the operations of various actuators, such as blower speed, a fresh air intake vent damper, an exhaust vent and a heat pump, so as to adjust the internal climate of the energy-efficient building towards a control point (e.g., an inside temperature and humidity comfort level).

An emissions recycling system is used on a vehicle towing an agricultural implement to enrich the fertility of the soil. The system includes an exhaust collector for collecting exhaust emissions from the internal combustion engine of the towing vehicle and an exhaust distribution system for injecting at least a portion of the exhaust emissions collected by the exhaust collector into the ground worked by the ground working tools of the agricultural implement. Fertility of the soil is enriched by bioactivity within the soil's micro flora which consumes the greenhouse gas and emissions.

Systems, devices, and methods to mitigate the pressure disturbance associated with the injection of low-pressure analyte samples into a high-pressure HPLC fluid stream, to enhance chromatographic performance related to retention time and reproducibility. The preferred embodiment coordinates the injection run with active pressure control of a binary solvent delivery system to virtually eliminate the customary pressure drop when the low-pressure loop is brought on line. An additional benefit that enhances reproducibility is accomplished by forcing a consistent timing relationship between the injection run, the mechanical position of the delivery pump pistons, and the start and subsequent gradient delivery.

A diagnostic control module includes a temperature gradient module. The temperature gradient module determines a temperature gradient across a selective catalytic reduction (SCR) catalyst of an exhaust system of an engine based on a plurality of temperature signals. A calibration module determines a weighted average based on the plurality of temperature signals. A SCR efficiency control module disables conversion efficiency monitoring based on the temperature gradient and the weighted average.

A method for controlling dosage of a reagent in a selective catalytic reduction (SCR) system includes the step of providing the system with a plurality of reagent injection nozzles, each nozzle being configured and adapted to be independently calibrated during an SCR reaction when the system is in operation. The method further includes determining an influence coefficient for each injection nozzle for a catalyst independently of the other injection nozzles, and optimizing the flow of reagent from each injection nozzle to minimize a sum of deviation across a surface of the catalyst. A system performs selective catalytic reduction (SCR) and a machine readable medium contains program instructions to controlling dosage of a reagent in a selective catalytic reduction (SCR) system.

The invention comprises systems and methods for ramping setpoints on thermostats controlling HVAC systems. At least one thermostat is located inside a structure and is used to control an HVAC system in the structure. At least one remote processor is in communication with said thermostat and at least one database stores data reported by the thermostat. At least one processor compares the outside temperature at least one location and at least one point in time to information reported to the remote processor from the thermostat. The remote processor ramps the setpoint on the thermostat so as to reduce the average spread between inside temperature and outside temperature in order to reduce energy consumption with affecting comfort. The remote processor takes into account the effect of weather conditions and occupant preferences in determining whether and when to ramp setpoints.
