  • Patent number: 9018877
    Abstract: A system for determining if a tire of a vehicle is improperly inflated. The system includes a radar, a wheel speed sensor, and a controller. The radar is configured to emit a signal to detect a reflection of the signal off of an object positioned perpendicular to the vehicle, and to output an indication of a speed of the vehicle. The wheel speed sensor is configured to sense a speed of a wheel of the vehicle. The controller is configured to receive the indication of the speed of the vehicle from the radar, to calculate a speed of the vehicle based on the sensed speed of the wheel, and to determine a tire of the wheel is improperly inflated when the speed of the vehicle calculated using the wheel speed sensor varies by more than a predetermined amount from the speed of the vehicle determined using the radar signal.

  • Patent number: 8292109
    Abstract: The invention relates to a pressure compensation device for compensating pressure between an inner chamber of a housing, in particular an electric motor, gearbox, container or the like and an outer side. The device includes a pressure compensation membrane mounted on an annular end face of a cylindrical structure that extends toward the outer side. The cylindrical structure is provided with a ventilation channel that extends therethrough. The cylindrical structure extends towards the outer side in order to form a projection from the wall of the housing, which projection is delimited by the end face on which the membrane is applied in a curved, dome-shaped form. A protective cover extends towards the outer side at a spaced apart distance in relation to the membrane over the cylindrical structure.
