Abstract: The invention will facilitate the creation of a wireless mesh network based upon a plurality of wireless dampers used in HVAC (Heating, Ventilation and Air Conditioning) for the purposes of sensing, controlling and responding to environmental and security devices or control fixtures within a building. Each building fixture includes a communication port and a controller. Each controller is configured to independently control at least one of an environmental or security device, either receive or help designate the building fixture as belonging to a group of building fixtures and propagate sensor and state information through the logical groupings of building fixtures and through the wireless mesh network via the communication port to a logical group control fixture that also operates as a floor-level wireless mesh network access point, end point control fixture controller message relayer and initiator of autonomous functions, information aggregator and disseminator.

Abstract: The present disclosure provides a method, apparatus, and system to mount a filter bag to a wet/dry vacuum cleaner by providing an adapter for mounting the filter bag to a drain opening in the wet/dry vacuum cleaner drum and restricting the typical vacuum port, forcing the vacuum materials to enter through the drain opening and into the bag. The lid of the wet/dry vacuum cleaner can be removed independently of the bag to avoid rupturing the bag. Further, the bag can rest on the bottom of the drum for support.

Abstract: A vacuum attachment assembly for a scroll saw wherein the scroll saw includes a base, a table, a table bevel lock knob, a table bevel plate, an upper arm and a lower arm-blade. The vacuum attachment includes a bracket having first and second ends. The first end of the bracket has an opening for receiving the table bevel lock knob. The second end of the bracket has an opening of predetermined size and is oriented so that the opening is located under the scroll saw table near the lower arm-blade assembly. The vacuum attachment assembly also includes an elbow that is connected to the opening of the second end of the bracket. A hose is connected to the elbow and oriented to collect and divert saw dust away from the table of the scroll saw.
