  • Publication number: 20240198944
    Abstract: A method for controlling an inflatable airbag system in a motor vehicle having a seatbelt includes detecting a position of a vehicle occupant relative to an airbag suppression zone (ASZ). Electronic input signals are received from a sensor suite, including an occupant position signal and a seatbelt usage status signal. A restraint capacity setting of the airbag is adjusted in response to the electronic input signals such that corresponding restraint activation logic is executed by the controller based on whether the occupant is belted or unbelted. Different ASZs may be used for belted and unbelted occupants. A motor vehicle includes a vehicle body defining a vehicle interior, an airbag, a seatbelt, a sensor suite for detecting a position of an occupant relative to the ASZ, and a controller operable for controlling a restraint capacity setting and location of the ASZ in accordance with the method.

    Abstract: A press-in-place seal for an interface between adjacent components, with the seal including a cylindrical structure arranged along a longitudinal axis and characterized by a J-shape in a cross-sectional view. The seal is arranged inside a first component and compressed by a second component when the PIP seal is installed within the interface. The J-shape includes a first stem section orthogonal to and extending toward the longitudinal axis for being compressed by the second component when the seal is installed within the interface. The J-shape also includes a second stem section longer than the first stem section, orthogonal to and extending toward the longitudinal axis, for stabilizing the structure when the seal is installed. The J-shape further includes a base third section arranged parallel to the longitudinal axis and connecting the first stem section to the second stem section, thereby defining a concavity between the first and second sections.

  • Publication number: 20240198968
    Abstract: Systems and methods associated with an electric vehicle are provided. The electric vehicle includes a sensor system, a communications system and a snow clearing system. The systems and methods detect, based on data from the sensor system, snow that may accumulate on a window of the electric vehicle. When snow is detected, a notification is provided, via the communications system, to a remote user device. The notification requests user acceptance of use of charge of a battery of the electric vehicle to operate the snow clearing system of the electric vehicle. The systems and methods receive, by the communications system, a response to the notification from the user device, and when the response indicates acceptance of the use of charge of the battery, the snow clearing system is activated. The snow clearing system is powered by the battery.

The method may also include generating and transmitting, a second chirp signal by a second sensor, in a second time-channel and in the first frequency-channel and the receiving, by the first sensor, a first reflection signal from objects from the first chirp signal. In addition, there may be a receiving, by the second sensor, a second reflection signal from objects from the second chirp signal. In addition, the first time-channel is orthogonal to the second time-channel, and the transmitting of the second chirp signal is offset in time from the transmitting of the first chirp signal by an amount less than a duration of the first chirp signal.
