  • Patent number: 10558229
    Abstract: A monitoring system for a heating, ventilation, or air conditioning (HVAC) system of a residential or commercial building includes an evaporator unit device and four temperature sensors. The evaporator unit device includes an electrical sensor that measures current supplied to a circulator blower of the HVAC system. The measured current from the first electrical sensor is used to diagnose a problem with the circulator blower. The first temperature sensor that measures a temperature of refrigerant flowing between a condenser of the HVAC system and an expansion valve of the HVAC system. The second temperature sensor measures a temperature of refrigerant flowing between an evaporator and a compressor. The third temperature sensor measures a temperature of air flowing away from the evaporator. The fourth temperature sensor measures a temperature of air flowing toward the evaporator. The evaporator unit device transmits sensor data to a remote monitoring service over a data network.

    Abstract: A control apparatus for an internal combustion engine detects an amount of particulate matter contained in an exhaust gas in an exhaust passage, according to an electrical property across electrodes of a particulate matter sensor disposed in the exhaust passage of the internal combustion engine. The term “electrical property” here refers to a property that changes with the amount of particulate matter deposited, for example, a current value of when a predetermined voltage is applied. After the internal combustion engine is started and detection of the amount of the particulate matter is completed, an element section of the particulate matter sensor is set to a predetermined temperature range. The particulate matter deposited on the element section is thereby burned and removed. The control apparatus maintains the element section in the predetermined temperature range after burning and removing the particulate matter until the internal combustion engine stops.

  • Patent number: 8919104
    Abstract: A control apparatus for an internal combustion engine detects an amount of particulate matter contained in an exhaust gas in an exhaust passage, according to an electrical property across electrodes of a particulate matter sensor disposed in the exhaust passage of the internal combustion engine. The term “electrical property” here refers to a property that changes with the amount of particulate matter deposited, for example, a current value of when a predetermined voltage is applied. After the internal combustion engine is started and detection of the amount of the particulate matter is completed, an element section of the particulate matter sensor is set to a predetermined temperature range. The particulate matter deposited on the element section is thereby burned and removed. The control apparatus maintains the element section in the predetermined temperature range after burning and removing the particulate matter until the internal combustion engine stops.

  • Patent number: 8882874
    Abstract: A unique, multi-cartridge, easily re-configurable ambient air filter assembly (air contaminant control system) that removes particulate and gaseous chemical/biological contaminants from the incoming cathode air stream on a fuel cell or similar devices is described. The filter assembly is composed of individual filter cartridges (sub-assemblies) of various filtration media that are targeted at removing specific airborne contaminants. Combining specific sets of cartridges enables the filter assembly to be readily/rapidly configured (and re-configured) for specific applications—such as urban, rural, industrial, or military battlefield environments. Selection of correct media ensures complete removal of potential contaminants, enables rapid re-configuration to different environments, quick replacement of spent cartridges without disposal of non-spent media (reducing waste and cost).

    Abstract: A method and a device for reducing the humidity of a gas in a housing interior, in particular in a battery housing interior, includes leading a gas through a first selectively permeable membrane and into an intermediate space. The intermediate space has the first selectively permeable membrane as an inlet and a second selectively permeable membrane as an outlet. The gas is then cooled in the intermediate space by a cooling unit such that a water vapor portion of the gas is condensed into water and the gas having a reduced water vapor content is directed through the second selectively permeable membrane into the housing interior.
