20130129344 | APPARATUS, SYSTEM AND METHOD FOR NETWORK MONITORING - Systems, methods, and devices are disclosed for monitoring optical communications between a managed location and a remote location. In particular, an optical signal is transmitted over an optical fiber and passed-through a test device. A portion of the optical signal is filtered from the original optical signal and passed to a monitoring unit. The monitoring unit may instruct one or more switches in the test device to loop the optical signal back toward the managed location. Subsequently, testing and monitoring may be performed at the managed location. The device may provide a test output or may transmit the information to the managed location. | 05-23-2013 |
20140373140 | DATA CENTER REDUNDANCY IN A NETWORK - Aspects of the present disclosure involve systems, methods, computer program products, and the like, for data center redundancy in relation to a computer network. In particular, the present disclosure provides for one or more available redundant data centers, or bunkers, associated with a computer network. In one embodiment, the bunker data centers are configured to absorb traffic intended for an application operating on a data center when the traffic threatens to overwhelm the application. For example, during a distributed denial of service (DDOS) attack, the bunker data centers are configured to absorb some of the traffic from the DDOS attack to prevent the application that is the target of the attack from being overwhelmed. | 12-18-2014 |

20090185864 | Automatic flooding protection for underground ventilation ducts - Embodiments are described for preventing downward flow of substantial surface water into an underground ventilation duct communicating upwardly to a ground surface opening. The embodiments comprise a support having a top opening and an opening in a lower portion above a floor. The opening in the lower portion is for venting communication with a proximate portion of the ventilation duct. The support supports at least one seat and paired buoyant gate set. The seat is mounted perpendicularly relative to the gate and a portion of a passageway under the seat for fluidly communicating beyond such portion to the top opening of the support and to the proximate portion of the ventilation duct. The buoyant gate is positioned lower than the seat and the passageway, is of sufficient size to block the passageway, and is responsive to water rising in the support by floatingly pivoting upwardly until engaging the seat, thereby blocking the passageway. In an embodiment, the seat of at least one set is mounted under the top opening spaced from one of the opposing sides a horizontal distance nominally equal to a fraction applied to a length for the particular opening, the fraction having the numerator 1 and a denominator which is the sum of 1 plus the number of seat and gate sets, and the buoyant gate has a seat engagement height nominally equal to the same fraction applied to the same opening length. | 07-23-2009 |
20120034032 | Self-Actuating Flood Guard - A self-actuating flood guard for a construction holds a buoyant gate at an elevation spaced from ground between flanking spaced vertical boundary walls adapted for connection to the construction. The gate is pivotable on pivotation members about a horizontal axis normal to the boundary walls for buoyant rotation upwardly between the boundary walls on rise of water above the elevation. Optionally, flexible lip seal gaskets along the sides of the gate sealingly wipe the boundary walls, and a flexible strip gasket across the pivotation members along the base of the gate prevents passage of water between the base of the gate and the construction. A restraint acts on the gate to prevent the gate from rotating about the axis more than a predetermined extent when the gate is pivoted upwardly above said elevation. | 02-09-2012 |
20120163916 | SELF-ACTUATING STORM SURGE BARRIER - The shore side of a shore line water barrier is protected by a disclosed construction and method from flooding caused by storm surge over-topping the barrier. Water overtopping the barrier, such as from wind waves crashing against the barrier, is trapped, impounded and accumulated between a parapet atop the barrier and walls on the sides of a buoyant gate unit taller than the parapet and walls and normally resident below grade on the shore side of the barrier, hinged about an axis generally parallel to the barrier and spaced from the parapet by a distance not less than the height of the gate unit. The accumulated overtopping water is applied to rotationally float the gate unit from the horizontal position initially principally by buoyancy and then principally by hydrostatic pressure to drive the gate unit to an upright position to oppose storm surges having a water level higher than the parapet. | 06-28-2012 |
20120163917 | SUPER ELEVATION SURFACE SELF-ACTUATING FLOOD BARRIER - Method and apparatus for preventing water from flooding along the length of a super elevation surface having a slope from an upper end to a lower end transverse to a longitudinal direction of the surface. A chain of rigid buoyant gate units of increasing heights is flexibly sealingly laterally linked together side by side for pivotable movement of the gate units about at least one pivotation axis, and if more than one axis, then about coplanar pivotation axes. The gate units are situated in a recess in and transverse to the longitudinal direction of the surface between a pair of walls lining the surface parallel to the longitudinal direction to which the pivot axis or axes is/are transverse. One of the walls is at a lower end of the slope and the other wall is at the upper end of the slope. The chain of panels rotates upward serially beginning with a gate unit closest to the lower wall and ending with a gate unit closer to the upper wall under the influence of water buoyancy and hydrostatic pressure, blocking water to one side of the upwardly rotated gate units. | 06-28-2012 |
20140169883 | Self-Actuating Shoreline Flood Guard - A series of self-actuating flood guard units each including a buoyant gate flanked by a pair of the boundary walls and pivotable about a horizontal axis transverse to the flanking boundary walls runs along a shoreline of an adjacent body of water The axis is located at a selected elevation above ground inundated by the body water and is selected to cause the gate to buoyantly rotate upwardly between the boundary walls on rise of water above the selected elevation. The extent of rotation is limited by a restraint acting on the gate. The series of units may be continuous or contiguous and act as a whole to prevent onshore flooding from a rise of the body of water at the shoreline. | 06-19-2014 |
20140369754 | SELF-ACTUATING FLOODWATER BARRIER - A floodwater barrier for protecting the shore side of a shoreline from flooding includes at least one self-actuating floodwater barrier unit for installation between a pair of walls transverse to a shoreline. The unit includes a flexible resilient panel, a plurality of rigid members connected to the panel, at least one watertight chamber of size and arrangement to give the unit water buoyancy, hinged to be rotatable upward about a horizontal axis longitudinal to the shoreline under the influence of buoyancy and hydrostatic pressure from a rise of the body of water acting on the unit, and further includes flexible tension members positioned to act on the floodwater barrier unit to limit upward rotation of the unit to a predetermined extent. | 12-18-2014 |
