Abstract: A roofing system and method, which includes elongate rain diverting devices for directing rainwater and snowmelt away from an underlying sheet material and roof deck, is provided. The system includes roofing tiles having strips of hook and loop fasteners (H&L strips) adhered to both faces. The rain diverting devices have an H&L strip adhered along a lower edge of both faces. As each new row of tiles is installed on the roof deck, the device is applied over an upper portion of the tiles, extending over and onto the sheet material above the tiles, and across the roof deck. As additional rows of tiles are installed, each device is releasably attached to underlying and overlying tiles by way of the H&L strips adhered to both the tiles and the device. The devices also allow for single lap tiling (less weight on roof deck) and for use of shorter tiles (saving material cost).

Abstract: Systems, methods, and computer-readable storage devices for providing directions haptically such that sight and hearing can continue unimpeded. In one exemplary embodiment, a wearable device (such as earphones, ear rings, gloves, glasses, or other wearable objects) configured as disclosed herein receives directions to an intended destination for a user, the directions comprising a movement action and a distance to the movement action. The wearable device has multiple haptic output units and generates, through one of those units, a haptic output based on the directions. This allows the user to receive the directions through touch rather than looking at their mobile device or from audio.

Abstract: A foil displacement system includes one or more foils that can be deployed and stowed. When deployed, each foil can exert downforce or uplift depending on its orientation. For example, each foil may be positioned to have an angle of attack that creates a downward force effectively transmitted to the hull to pull the hull deeper within the water to, for example, create a larger wake. Use of the foil displacement system can enhance or replace the use of a ballast tank system, can be integrated into a new boat or retrofitted to existing boats, can be electronically or manually positioned, can enhance activities such as wake surfing, wake boarding, water skiing or other similar or related water sports.

Abstract: Methods and systems for transmitting an interruption-free version of a television program for recording on a user equipment device. In one aspect, a system transmits a first stream including a television program to a user equipment device. The system receives an indication that the television program is being recorded on the user equipment device. The system determines whether an interruption is imminent during transmission of the television program. In response to determining that the interruption is imminent, the system generates a second stream including the television program. The second stream does not include the interruption during the transmission of the television program. The system transmits the second stream to the user equipment device along with an instruction to switch recording of the television program from the first stream to the second stream.

Abstract: Systems and methods are described herein for presenting additional information related to an emergency alert. A media guidance application may detect that a new emergency alert has been received. The media guidance application may then perform a search of various content sources (e.g., program listings, the Internet, etc.) for content related to the emergency alert. The media guidance application may then present the search results in a contextual menu enabling the user to access content of the search results. The media guidance application may also provide more options, such as, recording or pausing media content that the user was in the process of consuming when the emergency alert was generated, and an option to the user not to bring up the contextual menu again if the same emergency alert is repeated.

Abstract: Visualizing event impact risk over time. At least one location of interest is identified on a geospatial map, and an event path is plotted on the geospatial map for an event over time. The event path includes actual and/or forecasted paths of the event. Along the event path, connected geospatial polygons are generated. The geospatial polygons represent actual and/or forecasted intensity of the event over time. A determination is made as to whether the connected geospatial polygons intersect one or more of the locations of interest indicating an impact risk for the event. Action are taken to reduce the impact risk for the location of interest.
