  • Patent number: 10488070
    Abstract: A method of ventilation includes receiving at least one signal indicative of an operation of one or more exhaust fans causing air to be exhausted out of a building. The method further includes determining, by one or more processing devices, a total expulsion rate of air being exhausted out of the building by the one or more exhaust fans based on the signal, and determining, by the one or more processing devices, a target fan speed of one or more intake fans configured to draw external air into the building. The target fan speed of the one or more intake fans is determined to achieve an inflow rate that is substantially equal to the total expulsion rate. The method also includes controlling the one or more intake fans using one or more control signals in accordance with the target fan speed.

  • Patent number: 10323351
    Abstract: In a method for operating a tumble dryer for drying damp laundry, the profile of the moisture of the air in the tumble dryer, advantageously the absolute moisture, is measured during an initial phase of the drying process. The profile of the measured moisture is then compared with stored profiles for the moisture or a gradient of the profile of the measured moisture is compared with stored gradient threshold values for gradient values of the moisture. In this case, profiles and/or gradient threshold values for fibers from the following group: cotton, wool and synthetic fibers, and also an upper gradient threshold value and a lower gradient threshold value are stored.

  • Patent number: 8806772
    Abstract: A grain drying system includes a master control unit external to the grain storage bin which is preprogrammed with a desirable grain moisture content or EMC. Condition sensor assemblies mounted within the grain bin determine the relative humidity and the temperature of the grain within the grain bin. Also, sensors mounted in the bin's plenum determine temperature, relative humidity and air pressure. A weather station mounted externally of the grain bin determines the outside air temperature and relative humidity. Depending on the conditions determined by the sensor assemblies and the weather station, the master control unit selectively activates the grain bin's drying fan when needed and when it is efficient and effective to do so. A radio or cellular modem allows for communication of the grain's condition. The internal sensor assemblies are preferably secured to flexible cables hung within the grain bin. The cable and rigid rod-like members support the sensors.

  • Patent number: 7966742
    Abstract: A method for increasing the efficiency of an internal combustion engine utilizes three three-way valves, one that receives ambient air through an air cleaner, a second that receives hot exhaust from a catalytic converter of the internal combustion engine, and a third that receives air from a high speed blower. The three-way valves direct ambient air through the air cleaner and into a first of three dryer canisters, and direct the dried ambient air through an ozone generator to the internal combustion engine, while concurrently directing gas from the exhaust catalytic converter to the second of the three dryer canisters, and also concurrently directing air from the high speed blower to the third of the three dryer canisters.
