20100313476 | PERISCOPING VANES FOR SMART WINDOWS - Methods and devices are provided for selectively allowing light to pass through a substantially transparent substrate or blocking the light, at least to some degree. Some embodiments provide a plurality of reflective vanes that can be positioned in at least two positions. According to some such implementations, when the vanes are in an open position, incident light is allowed to pass through the window. The light may reflect from two or more vanes before passing through the window. When a sufficient voltage is applied between vane electrodes and other electrodes, the vanes are pulled down, reflecting back at least some of the incident light. The voltage may be controlled according to detected temperature, ambient light intensity, etc. | 12-16-2010 |
20130086839 | Dual Torque Active Grille Shutter for Snow and Ice - An active grille shutter system comprising a controller, a sensor provides a freeze signal to the controller when a temperature is near or below freezing, and an electric motor that opens and closes a plurality of vanes. The motor receives a low current signal from the controller to operate the system at a first torque level and receives a high current signal to operate the system at a second torque level when the controller receives the freeze signal. A precipitation signal from the windshield wiper system of the vehicle is provided to the controller to provide an indication that there is precipitation present in the vehicle environment. The controller may provide the high current signal to the motor only when the freeze signal and the precipitation signal are provided to the controller. A method is also provided for operating the system. | 04-11-2013 |
20130263510 | METHOD FOR THE INDIVIDUALIZED AND AUTOMATED CONTROL OF THE MEANS FOR CLOSING OFF AT LEAST ONE WINDOW, CONTROL ASSEMBLY FOR IMPLEMENTING SAID METHOD, AND PARAMETER-SETTING TOOL FOR SAID ASSEMBLY - A method for individualized control of means for closing off at least one window, by: determining coordinates of a dazzle cone associated with a window and with a dazzle-sensitive zone, the dazzle cone defined by a vertex positioned at the dazzle-sensitive zone and a directrix curve superimposed on the perimeter of the window; determining the orientation of direct rays of sunlight, and defined by a solar azimuth and a solar elevation; periodically checking whether the orientation falls within a predetermined dazzle cone; the directions of the rays of sunlight being parallel to one of the directions within the dazzle cone and passing through the vertex of the cone; and acting on closing-off means associated with the window for which orientation of rays of sunlight falls within a dazzle cone. | 10-10-2013 |
20130305607 | SMOKE AND HEAT EVACUATOR - A smoke and heat evacuator that can be applied at an opening of a generally vertical wall of a closed environment, includes a supporting frame bearing a shutter, which oscillates between a normally closed position and an open position via at least one lateral linkage having a first arm that, in the closed position, extends obliquely, with a top end articulated to the shutter via a slider subject to the downward-thrust action of a spring and with a bottom end articulated to the supporting frame via a second lengthenable arm. | 11-21-2013 |

20110088322 | CLOSURE ASSEMBLIES FOR FIRE DOORS, FIRE DOORS INCLUDING SUCH CLOSURE ASSEMBLIES AND METHODS OF LOCKING FIRE DOORS - In one embodiment, a closure assembly for a fire door, including a first lead post having a longitudinal cavity located therein, an opening extending through a wall of the first lead post into the longitudinal cavity and a locking member may be positioned within the longitudinal cavity that is configured to obstruct the opening into the longitudinal cavity upon reaching a predetermined temperature, is disclosed. In additional embodiments, fire doors including such closure assemblies and methods of locking fire doors are disclosed. | 04-21-2011 |
20130174487 | LOCKLESS METAL FIREPROOF DOOR - A lockless metal fireproof door is pivotably mounted to an outer frame and includes two metal sheets, with a fireproof mechanism mounted in each metal sheet. A hinge is mounted to a bottom of the lockless metal fireproof door for automatically returning the lockless metal fireproof door, with a gap provided between each metal sheet and the outer frame. The lockless metal fireproof door can be moved to a position and retained in the position by the ground hinge. The lockless metal fireproof door is positioned by a weight thereof after the lockless metal fireproof door reaches the position. The lockless metal fireproof door expands in a lateral direction to tightly press against the outer frame if a side of the lockless metal fireproof door is subjected to heat. | 07-11-2013 |
