  • Patent number: 10948209
    Abstract: A system and method for controlling HVAC equipment in a residential setting. The system may include an outdoor temperature sensor positioned to measure outdoor temperatures, an indoor air temperature sensor to measure indoor space air temperatures, a supply duct air temperature sensor positioned to measure supply duct air temperatures, a return duct air temperature sensor positioned to measure return duct air temperatures, an air blower current sensor positioned to measure air blower currents, and/or an air compressor current sensor positioned to measure air compressor currents, and a controller operable to receive the measures of outdoor temperature, indoor space air temperature, supply duct air temperature, return duct air temperature, air blower current, air compressor current, and measures of solar irradiation intensity and wind speed. The controller may be programmed with instructions to input the measures into a thermal model for outputting signals for implementing changes in the system.

  • Patent number: 7257085
    Abstract: A wireless communication network with improved performance and a method and controller for controlling data rate in the network are provided. The invention provides a feedforward approach to data rate control in wireless networks. The invention is based on designing an optimal, but non-causal, controller and its subsequent “causification,” which results in a practical, implementable controller, driven by an estimate of the bit error probability. This controller leads to a minimum 5%-85% increase in average throughput without additional power utilization, as compared with fixed data rate operation.
