Abstract: A system or method utilizes one or more outside sensors to measure one or more outside air parameters, and optionally one or more inside sensors to measure inside air parameters. A processor is configured to at least partially control the operation of an air cleaner based on at least one of the one or more outside air paraments, or a comparison of at least one of the one or more outside air parameters to at least of one of the one or more inside air parameters. The system and method may use artificial intelligence to provide additional information to the controller to assist in controlling the air cleaner.

Abstract: A system includes a surface device, preferably positioned on a surface, a downhole device, and a wireline communications system. A downlink communication between the surface device and the downhole device occurs via Hopped Frequency Shift Keying (HFSK) voltage-modulated signals. An optional uplink communication between the downhole device and the surface device may occur via Frequency Shift Keying (FSK) current-modulated signals. The downhole device may comprise an addressable switch.

Abstract: A gun-tube extension has (1) a body portion, (2) a first end configured to connect to an end cap of a gun tube, and (3) a second end configured to be connected to a sub-assembly. The gun-tube extension may rotate either by the operation of gravity on weights or by a motor. The gun-tube extension may include an orientation-detection device, such as an accelerometer, which may be part of an addressable switch. A ground for a gun tube or gun-tube extension may include a bow spring attached to and in electrical communication with the gun tube housing or the gun-tube extension housing. An end cap may include indexing indicia to orient a gun tube to a desired rotational position and/or may be structured to fit different diameter gun tubes.

Abstract: An air ionization unit is provided to ionize air to remove particulates and to release cleaned air. Air moves into the air ionization unit where it may be first filtered by an air intake filter. The air is moved, preferably by a fan, into contact with an ion generator, where the air is ionized. One or more (such as two) other fans may be used to provide airflow to (1) at least partially remove ions emanating from the air that has been exposed to the ion generator, and (2) to push the cleaned air through one or more ozone filters and out of the air ionization unit. The air ionization unit may also include an outgoing air filter, and one or more doors to access the air intake filter and/or the air ionization unit.

Abstract: Ionization systems configured with a catalyst-bearing sleeve provide improved filtration while filtering ozone. Modular configurations provide for serviceability and replaceability. System controls may be used to monitor particulates, temperature, humidity, and other relevant factors and adjust an ionization level accordingly.

Abstract: This invention relates primarily to an electric heater based tankless water heater, though some aspects may also apply to a natural gas or other fuel based tankless water heater. In particular aspects relating to “smart” communication and coordination of the tankless water heater with other devices, which may be electrically powered or powered by other fuels, may also apply to non-electric flow through fluid heating systems. The subject tankless water heater invention incorporates several aspects relating to energy and construction efficiency which will be detailed further. These include both physical aspects, such as coatings, tubing and heater element design, and electrical aspects, such as power control for individual heater elements, which can make the tankless water heater more compact and more efficient in operation, with reduced instantaneous and long term load on electrical supply systems.
