Abstract: A separator unit includes a tank defining an internal volume and having an inlet and an outlet. An insert is provided within the tank, the insert including a down cylinder substantially centrally disposed within the tank and a baffle assembly at an external side of the down cylinder. The baffle assembly defines first and second inlet flumes for flowing incoming water from an external side of the down cylinder to an internal volume within the down cylinder. Inward ends of the first and second inlet flumes are positioned and oriented to create first and second vortex flows that progress downward within the internal volume, wherein a rotational direction of the first vortex flow is opposite a rotational direction of the second vortex flow in top plan view.

Abstract: A rainwater collection system is described which includes generally a rainwater routing system and a collection unit. The rainwater routing system may comprise a first flush diversion unit designed to discharge to a run-off path, an initial amount of rainwater such that initial particulate matter from rooftops, etc., are not collected. The rainwater routing system may comprise a pre-treatment unit, the pre-treatment unit designed to remove particulate matter from the rainwater. The collection unit of the rainwater collection system comprises a storage tank having an internal day tank compartment. The described rainwater collection system allows for the collection of rainwater with a substantially reduced amount of particulate matter.

Abstract: A signal mapping system maps sensor signals into control signals that control the operation of a music synthesizer. A "one to many" mapping technique is used, allowing at least some of the sensor signals to each be mapped into numerous music synthesizer control signals. Physical gestures by a user are mapped into a large set of music synthesizer control signals, some of which continuously vary in value as the user moves through the gestures. Signal mapping functions are used to map the sensor signals into note number and velocity values for at least one voice to be generated by the music synthesizer. The note number and velocity values are sent to the music synthesizer as note-on events when predefined note-on and note-off trigger conditions, defined with respect to specified ones of the sensor signals, are satisfied. Other ones of the signal mapping functions are used to generate asynchronous control signals that are sent to the music synthesizer independent of the note-on and note-off events.
