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: A system and method for providing updates to medical devices is disclosed. In one example, the medical devices are configured to pull update files in response to the reception of an update message from a server.

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.
