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: 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: 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, methods, and apparatus are described for a locking folding knife having a handle lock and a safety switch arranged around and rotatable around a pivot axis of the knife. In an engaged position the switch overlaps at least a portion of the handle lock and prevents it from moving into an unlocked position. A spring, such as a wire form spring, can be arranged within a pocket of the switch, and when the switch is moved between engaged and disengaged positions the spring can be compressed generating a rotational bias on the switch urging the switch toward either the engaged or disengaged position.

Abstract: A shade system includes a first linear actuator attachable to a structure, and a second linear actuator spaced from the first linear actuator and attachable to the structure. The first and second linear actuators are each displaceable between a retracted position and an extended position. A canvas connected between the first and second linear actuators is fixed to distal ends and to proximal ends of the first and second linear actuators and is free-floating between the distal and proximal ends. The canvas is configured to retract into an accordion configuration when the first and second linear actuators are displaced from the extended position to the retracted position.
