  • Patent number: 11911948
    Abstract: The invention discloses a starch-based multi-channel airflow unit and a preparation method and an application thereof. The preparation method of the present invention comprises the following steps: melting a polylactic acid, wherein a temperature of a first temperature control zone is 135° C. to 145° C., a temperature of a second temperature control zone is 175° C. to 185° C., a temperature of a third temperature control zone is 190° C. to 200° C., and a temperature of a fourth temperature control zone is 175° C. to 185° C.; gelatinizing a starch-based material, adding the starch-based material in the third temperature control zone and fully mixing the mixture; adding a polyol in the third temperature control zone, and fully mixing the mixture; and extruding out the mixed material through twin screws, sizing in vacuum, cooling and sizing, and winding and cutting to obtain the starch-based multi-channel airflow unit.

  • Publication number: 20190368878
    Abstract: The invention relates to a method for determining an orientation (?) of a vehicle relative to a spatially fixed coordinate system (x0-0-y0), the method comprising the following steps: determining a traveled distance (S,dS,?S) of at least one reference point (P) of the vehicle and/or at least one wheel of the vehicle, and calculating the orientation (?) of the vehicle taking the traveled distance (S,dS,?S) into consideration. The invention further relates to a method based on this principle for determining a position (XP,YP) of a vehicle, to a method for determining an odometry of a vehicle, and to a corresponding control device of a vehicle.

  • Patent number: 9744862
    Abstract: A braking system for a motor vehicle, including friction brakes on the wheels of at least one axle, the brakes controlled by a friction brake control device; at least one electric machine connected to at least one wheel and controlled by an electric drive control device; a brake pedal for detecting a deceleration request; a wheel-slip controlling device; and a torque distributing device. The devices for detecting a deceleration request are connected to the wheel-slip controlling device, the wheel-slip controlling device specifying target braking torques for each wheel according to the parameters of the deceleration request. The wheel-slip controlling device connected to a torque distributing device which is connected to the friction brake control device and the electric drive control device and which specifies friction brake requests to the friction brake control device and generator brake requests to the electric drive control device according to the target braking torques.

  • Patent number: 8583300
    Abstract: An automatic stabilization unit for watercraft such as boats, yachts and the like. In order to ensure stabilization of the watercraft with a high level of movement comfort at the same time over the entire speed range and in all water conditions, an electronic regulator is provided which stabilizes the water attitude of the watercraft during movement, while moving straight ahead and turning, as a function of the movement-situation-dependent rotation rates and longitudinal accelerations and/or lateral accelerations and/or vertical accelerations, using the actuating elements which are normally available in the watercraft, thus preventing or reducing to a minimum any stress on, damage to or danger to the boat, its occupants and the surrounding are thereof.
