In an embodiment an indoor air quality monitoring system is included having a control circuit, a memory circuit, and a sensor channel interface. The system can be configured to store a model set of data reflecting information on air quality determining features within a physical indoor environment, receive sensor data regarding air quality at discrete points within the physical indoor environment, and evaluate the sensor data regarding air quality and perform operations to generate one or more outputs relating to air quality within the physical indoor environment. Other embodiments are also included herein.

The article may be a vent. A method of making the hydrophobic article includes applying a hydrophobic material onto a permeable material; and curing the hydrophobic material to form a hydrophobic surface. The hydrophobic coating may include siloxane.
The present disclosure relates to a cassette assembly. An inlet cassette plate defines an inlet cassette inlet flow path and an inlet cassette outlet flow path. An outlet cassette plate is configured to be arranged in a stack with the inlet cassette plate. The outlet cassette plate defines an outlet cassette inlet flow path configured to be laterally aligned with the inlet cassette inlet flow path, and an outlet cassette outlet flow path configured to be laterally aligned with the inlet cassette outlet flow path. An inlet plug is configured to be inserted in the outlet cassette inlet flow path. An outlet plug is configured to be inserted in the inlet cassette outlet flow path. The inlet and outlet plugs are configured to be removable and reinsertable. A separation layer is disposed between the inlet cassette plate and the outlet cassette plate.
The present technology relates to a cassette assembly having an inlet cassette plate defining an inlet flow path, and an outlet cassette plate defining an outlet flow path. The outlet cassette plate is configured to be arranged in a stack with the inlet cassette plate. A membrane stack is disposed between the inlet cassette plate and the outlet cassette plate. The inlet flow path is configured to be in fluid communication with the outlet flow path through the membrane stack to form an assembly flow path. The cassette assembly is configured to receive an elution solution, and an elution concentration is substantially constant as the inner nominal volume varies.

Provided herein are fusion proteins comprising a first polypeptide and a second polypeptide, wherein the second polypeptide has phase behavior. The first polypeptide may be a polypeptide having a desirable biological activity, such as a polypeptide with therapeutic, cosmetic, and/or industrial importance. Fusing the first polypeptide to the polypeptide with phase behavior facilitates purification thereof, and may also help to stabilize the first polypeptide during expression, storage, or after exposure to various conditions known to unfold, degrade, or misfold proteins.

A vent having a vent housing defining a mounting structure, a first opening between a first end and a second end of the vent housing, a first airflow pathway from the first opening, a second airflow pathway from a second opening, and a draining pathway from the first airflow pathway through the first end of the vent housing. The first airflow pathway has a first segment and a second segment extending in opposite axial directions. An inlet relief valve and an outlet relief valve are arranged in parallel between the first and second airflow pathways. The inlet relief valve opens upon exceeding a first threshold pressure differential of the second relative to the first airflow pathway. The outlet relief valve opens upon exceeding a second pressure differential of the first relative to the second airflow pathway. A filter assembly is disposed in the vent housing across the second airflow pathway.
A filter system includes a tube sheet defining a plurality of holes in fluid communication with a plurality of filter bags. The system also includes a rotating assembly having an arm defining one or more outlets to provide pressurized air from an air source toward the tube sheet in response to pulsing one or more actuators. A motor is operably coupled to the stationary assembly and the rotating assembly to rotate the arm about an axis at a preset rotational speed. A controller is operably coupled to the motor and the one or more actuators to provide pulse commands based on a pulse interval and a jog interval. The pulse interval and the jog interval may be determined based on a measured rotational speed of the arm, which may be redetermined during operation.
