    • Force and deceleration delimiting devices and methods for operating the same in a vehicle. The devices generally include an open celled material expandable from a non-expanded state to an expanded state, wherein the open celled material is sandwiched between a first end cap member and a second end cap member; an optional support surface cooperatively positioned with the open celled material to cover a surface of the open celled material in the expanded and the non-expanded states; and an optional shield cooperatively positioned with the open celled material to cover a surface of the open celled material in the expanded and the non-expanded states; and an activation mechanism adapted to regulate selective expansion of the open celled material from the non-expanded state to the expanded state in response to a triggering event, wherein the support surface and/or shield have a compact shape when the open celled material is in the non-expanded state and an expanded state when the open celled material is in the expanded state.

    • A wet road surface detection system is provided for a vehicle driving on a road. The wet road surface detection system includes a sound sensing device coupled to the vehicle for capturing noise of the vehicle tires as the vehicle drives on a road surface. A processor processes sounds captured by the audible sensing device. The processor quantifies a variable sound level of the captured noise between a first frequency and a second frequency. The processor determines whether each quantified sound level between the first frequency and the second frequency is above a predetermined sound level threshold below the sound level at the first frequency. The processor determines that the vehicle is driving on a wet road surface in response to each quantified sound level between the first frequency and the second frequency being above a predetermined sound level threshold below the sound level at the first frequency.
    • 一种用于在道路上行驶的车辆的湿路面检测系统。 湿路面检测系统包括耦合到车辆的声音传感装置,用于在车辆在路面上行驶时捕获车辆轮胎的噪声。 处理器处理由可听觉感测装置捕获的声音。 处理器对第一频率和第二频率之间的捕获噪声的可变声级进行量化。 处理器确定第一频率和第二频率之间的每个量化声级是否高于低于第一频率的声级的预定声级阈值。 处理器响应于第一频率和第二频率之间的每个量化声级高于低于第一频率的声级的预定声级阈值,确定车辆在湿路面上行驶。
