  • Patent number: 11390335
    Abstract: A system and apparatus for increasing the safety of motor vehicles traveling at high speeds in the rearward direction is provided. An air dam hingedly secured to the aft end of a vehicle may remain in a stowed position while the motor vehicle is traveling in a forward direction so as not to interfere with aerodynamic performance. When a motor vehicle begins to enter a spin, the air dam may deploy and increase the downward force on the vehicle and as well as act as an air brake, thereby reducing the likelihood of the aft end of the vehicle lifting from the surface during a spin-out at high speeds.

  • Publication number: 20210146072
    Abstract: An operating unit (2) sets ventilation parameters of a control unit (11) of a ventilator (1) that includes a gas dispensing device (10) for ventilation gases. The operating unit includes a display unit and an ventilation parameters input element (23, 24). Two or more of the parameters are linked via a relation condition stored in a relation storage module (40). A relation monitor (3) includes a deviation detector (31) detecting a transgression of the relation condition during parameter setting, and outputs warning information via a warning unit (32). This avoids a need for an operator to note the sometimes complicated connections and dependencies expressed in the relations during the parameter setting. The warning may be sent before the new setting value is sent from the operating unit to the control unit. Operating safety is increased and a risk of setting errors is minimized.

  • Patent number: 10662924
    Abstract: The invention relates to a control apparatus and method for controlling the rotor blades of a wind turbine, and in particular to controlling the rotor blades during an extreme wind event. An extended mode of operation of the wind turbine rotor beyond the cut-out wind speed is provided. In the extended mode of operation, the pitch of the wind turbine blades is actively controlled so that the rotor and the generator idle at a designated rotational speed. The rotational speed may be relatively high, say 15 to 20% of the nominal speed, compared with minimal speeds experienced by purely feathered wind turbine blades, and may be further controlled as a function of the incident wind speed. Output power control in the extended mode may be zero but is preferably a low, but non-zero value. The output power so produced may then be used as an auxiliary power source for controlling the wind turbine in situations where the utility grid fails.

  • Patent number: 10619623
    Abstract: The present invention refers to a method for operating a wind turbine, the wind turbine particularly comprising a tower and a rotor with rotor blades. The pitch angles of the rotor blades are adjusted to generate a force on the rotor and the tower. The force is adjusted to counteract and damp an oscillation. The adjustment is enabled by an activation decision unit, if the activation decision unit decides that certain parameters characterising the oscillation or loads of the tower indicate a requirement and/or if the activation decision unit determines that the generated force is sufficient to counteract an oscillation of the tower.

  • Patent number: 10502186
    Abstract: Methods and systems for controlling a wind turbine in a manner that takes into account the degree of loading of and damage to one or more components of the turbine are provided. An operational load on a wind turbine part is determined, and is used to compute a damage signal. The damage signal is indicative of the potential damage to the component or to the turbine as a whole that will result if action is not taken to reduce or mitigate the determined load. When the damage signal exceeds a pre-determined threshold, load-reducing wind turbine control means are activated to obviate the estimated damage.
