Abstract: An air filter including an open end, a closed end, and a filter area there between. The open end frictionally engages and seals an air port, while the closed end mates with the housing to secure the filter to the housing. The filter area is reinforced to provide a durable, reusable filter. The filter material is selected to provide depth loading and increase the particulate capacity of the filter.

Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter includes a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium includes a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame includes a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

Abstract: An air filter including a base and a first and second frame element is disclosed. Each frame element is coupled to the base. The frame elements have an oscillating shape having a first portion relatively close to the base and a second portion relatively farther from the base. A filter element generally follows the oscillating shape of the frame elements. An air filter system is also disclosed. The air filter system can include the air filter and an air filter container. The air filter container contains the air filter and directs air through the air filter in a predetermined direction. An air filter is disclosed including a support structure and an oscillating shaped filter element attached to the support structure. The oscillating shape increases the air filter surface area for a given volume.

Abstract: An apparatus and methods are provided for a portable mass airflow (MAF) training module configured to simulate an air intake into an internal combustion engine. An in-line blower draws an airflow through an air filter by way of a first air duct and a second air duct. A throttle assembly is coupled between the first air duct and the second air duct. The throttle assembly includes a throttle plate that may be rotated to regulate the airflow. The power output of the in-line blower is variable to simulate the air intake of various sizes of the internal combustion engine. A MAF sensor and a duct velocity sensor are configured to provide airflow information. The portable MAF training module enables a practitioner to select a desired throttle setting and observe a resultant mass airflow through the portable MAF training module that is measured by the MAF sensor.

Abstract: An apparatus and methods are provided for a pass-through dongle for accessing and interacting with vehicle performance and status data. The dongle includes a first connector for plugging into an OBD-II connector of a vehicle. A wireless connection may be established between the dongle and a mobile device that provides access to and interactivity with the vehicle performance and status data. A second connector comprising the dongle is configured to receive an auxiliary device that is configured to access vehicle status data by way of the OBD-II connection. The dongle simultaneously establishes the wireless connection with the mobile device and provides the auxiliary device with access to the vehicle performance and status data. In some embodiments, the dongle is configured to operate in conjunction with a vehicle diagnostic communication system that includes a vehicle performance system whereby the vehicle performance and status data may be interactively accessed.

Abstract: An apparatus and method are provided for an air filter configured to be mounted onto an air inlet of an internal combustion engine. The air filter comprises a first end cap configured to couple with a base which is configured to support a conventional air filter and provide an interface between the conventional air filter and the air inlet. A filter medium which is relatively thicker than the conventional air filter is configured to remove particulate matter and other contaminates from an incoming airstream. A second end cap is configured to couple with a cover which is configured to fasten the conventional air filter and the base onto the air inlet, such that the incoming airstream is directed through the filter medium. The air filter is configured to be installed in place of the conventional air filter without necessitating alteration of the base and cover.

Abstract: An apparatus and method are provided for a drone elimination muffler to attenuate drone exhibited by engine exhaust systems. The drone elimination muffler comprises a hollow canister having a length and a diameter, and a tuned port comprising a first end connected to the canister and a second end connected to the exhaust system. The canister operates in concert with the tuned port as a dampener configured to substantially attenuate exhaust drone, or resonance, at one or more frequencies of engine operation. A valve is configured to switch the drone elimination muffler between a closed state in which the exhaust system operates without acoustic influence due to the drone elimination muffler, and an open state in which the drone elimination muffler directly influences the acoustic properties of the exhaust system.
