Abstract: A control system is disclosed that includes a room controller transmitting signals to both a shade control network and a light control network, directing that motorized roller shades and dimmable lights be set to desired intensity levels. The control system further includes an intelligent hub that provides a trickle-charge re-charge current via power-over-Ethernet cables to batteries associated with each of the motorized roller shades for re-charging the batteries, thereby eliminating power supplies being installed within walls. The intelligent hub provides for communication with the room controller based on streaming protocol and with the shade control network based on event-based protocol. A computer running user-interface software can be connected to the system to facilitate programming.

Each of the left and right speakers are mounted on respective side walls such that their long axis is substantially vertical, and the bulk of the speaker, which is contained within the frame of touch screen control device, faces inwardly, in a substantially horizontal direction, so that a minimal amount of depth is needed to mount touch screen control device.

Abstract: Systems, methods, and modes for on-demand rendering of a three-dimensional building management system visualization of a building. The system comprises a database configured for storing geometry elements and spatial elements. The geometry elements are mapped to spatial elements, wherein the geometry elements define three-dimensional geometrical representation of a building's structure, and the spatial elements define three-dimensional representation of spaces in the building. The spatial elements are associated with respective space nodes that identify the spaces located within the building, and the space nodes are associated with respective electronic devices installed within the spaces in the building.

Abstract: A motorized window treatment configure for automatically determining and reporting the tilt level of a motorized window treatment. The motorized window treatment comprises a window covering material, a motor configured for moving the window covering material from an opened position to a closed position, an accelerometer configured for measuring gravitational forces, and a controller configured for reporting the tilt level of the motorized window treatment. Particularly, the controller receives gravitational force measurements from the accelerometer, determines a tilt level of the motorized window treatment using the gravitational force measurements, compares the tilt level to a first threshold value, and issues an error signal when the tilt level exceeds the first threshold value.
