20110121087 | UNDER-FLOOR TROUGH WITH HEATING ELEMENT - An under-floor trough is provided for use with a raised-floor system. The under-floor trough includes an air-delivery assembly, one or more plurality of dampers, a support system, and a heating element. A control unit, removable from above the raised-floor system, and a baffle are disposed within the air-delivery assembly. The dampers include vanes that are actuated between open and closed positions according to a time modulated duty cycle to control the flow of conditioned air to a room. The support system provides a plurality of legs disposed between the bottom of the air-delivery assembly and a sub-floor. A bracket is mounted to a wall and the under-floor trough is supported thereby. The heating element is disposed within the air-delivery assembly. Conditioned air is provided to a room at high flow rates for short durations based on the duty cycle, thereby increasing the uniformity of cooling provided to the room. | 05-26-2011 |

20120100798 | DATA CENTER MODULAR INTEGRATED FLOOR DIFFUSER AND ASSEMBLY - A floor terminal mounted in a passageway beneath a raised floor utilizing a suspension system is provided. The suspension system includes a grid of interconnected longitudinal and lateral rails. Each of the rails includes an upper wall for supporting a grate assembly or a segment of the raised floor, and a lower wall that has an elongate aperture formed therein. The floor terminal includes a frame that is configured with outwardly extending flanges. A plurality of hook elements are provided for coupling the frame to the rails of the grid. Specifically, each hook element includes an upper angled portion that is inserted through the elongate aperture of one of the rails and rests upon an internal surface of the rail's lower wall. Additionally, each hook element includes a lower-angled portion that engages one of the frame's flanges, thereby suspending the floor terminal within the passageway. | 04-26-2012 |

20150099456 | AIR DIFFUSER WITH MANUAL AND MOTORIZED PLATES - A mechanism for opening and closing a damper valve of a diffuser mechanism is provided. Embodiments of the invention include a damper construction that selectively alters the amount of air flow through a diffuser grille using a three-plate damper valve. The three-plate damper valve includes a manual plate, a fixed plate, and a motorized plate. The manual plate is manually rotatable around a central axis, while the motorized plate is mechanically rotatable about the same axis. The motorized plate is mechanically and/or remotely controlled using a stepper motor coupled to the motorized plate. Further, the diffuser mechanism includes a sensor for determining the location of the motorized plate with respect to a starting position. As such, multiple configurations of the manual plate and the motorized plate may be used to alter the air flow through the resulting channels of the damper mechanism. | 04-09-2015 |
