A front flying line kite depower system includes a line sheath that extends through a transverse opening in the control bar. A front flying line parting fitting is non-rotatably fixed to an upper end of the line sheath above the control bar. When a manual rotation force is imparted to the line sheath, the relative positioning of a first front flying line and a second front flying line is altered by the front flying line parting fitting to untangle any twisting above the line sheath. Within the line sheath, the second front flying line is off-set from a primary axis and orbits the first front flying line which is positioned on the primary axis to avoid any tangling during manual adjustment.

The disclosure provides methods and devices for enabling a Vessel propelled by a Kite or similar devices, e.g., a balloon, to adjust its direction of travel to either side of the true wind direction without the aid of rudder(s), tiller(s), or similar devices. The subject invention applies to wind-powered Vessels as well as hybrid vessels and vessels utilizing propeller-driven propulsion, jot propulsion and others in addition to wind power.

A bar for controlling a kite comprises a trimming unit for the control lines (back line trimming unit). A length of the control lines can be adjusted by the trimming unit. The trimming unit is mounted in or on the bar and can be adjusted by means of a motor, preferably an electric motor.

A hand-held wing is configured to include an inflatable leading edge from which a substantially rigid boom extends which is configured to be held by the user to guide the wing, with the leading edge being configured to extend about V-shaped or U-shaped upwards (away from the surfer) in the direction of approach.

A fuel cell vehicle includes a bypass valve positioned downstream of a compressor and upstream of a fuel cell stack to selectively direct airflow from the compressor to an exhaust bypassing the fuel cell in an attempt to clear a partially or fully obstructed exhaust pipe. The bypass valve may be opened by a controller when an exhaust throttle valve is at or near a wide-open throttle position. The controller may also increase compressor flow and adjust airflow to the fuel cell stack until compressor pressure, speed, or temperature exceed corresponding limits.

The invention relates to a winding device (30) for winding up and unwinding lines (50) of a stunt kite, paraglider or parachute (60) with at least three reels (11) for receiving at least one line (50) of the stunt kite, paraglider or parachute (60). According to the invention, at least two reels (11) have their own reel drive (14) for winding up and unwinding the line (50) taken up on the reel (11).

A control bar stopper includes a stopper body having a sleeved line receiving slip groove that allows sleeved line slippage. The stopper body has an underlying control bar bumper. A brake body is provided having a sleeved line receiving stop groove that resists sleeved line slippage. The brake body is smaller than the stopper body and is positioned above and at a distance from the control bar bumper with the stop groove facing the slip groove. A pivotal link connects the stopper body and the brake body. In response to a control bar striking the control bar bumper, the slip groove allows the stopper body to slide along a sleeved line and as the stopper body slides along the sleeved line, the brake body pivots about the pivotal link into stop contact with the sleeved line with the stop groove resisting further slippage.
