Abstract: According to an aspect of the present disclosure, an air quality management system may include a mobile application distributed to at least one user device, at least one air quality management device, and at least one computing resource, wherein the at least one computing resource operates a first networking layer configured to receive input from the at least one mobile application. Also, the at least one computing resource operates a second networking layer that receives input from the at least one air quality management device. The air quality management system may further comprise a data connection between the first and second networking layers to transfer commands of the at least one mobile application from the first networking layer to the second networking layer, and to transfer device information of the at least one air quality management device from the second networking layer to the first networking layer.

Abstract: Embodiments of a power table saw are described which have a frame structure configured to support a movable saw assembly. The table saw also includes a rip fence attached to the frame structure in a fixed position for contacting a work piece during a cutting operation by said table saw. Further, a table assembly is provided, having a top surface for supporting a work piece, a blade extendable through an opening in the top surface for cutting a work piece, and a motor mounted beneath the top surface for driving the blade. The table assembly is movably mounted on the frame structure so that the table assembly is adjustable, allowing adjustment of the distance between the blade and the rip fence.
