Abstract: A panel assembly includes a first panel defining a surface, and a boom attenuation panel. The boom attenuation panel includes a circumferential edge, and a central portion. The boom attenuation panel is attached to the surface of the first panel, along the circumferential edge of the boom attenuation panel. The central portion of the boom attenuation panel is spaced from the surface of the first panel a gap distance to form a gas chamber between the surface of the first panel and the central portion of the boom attenuation panel. The gas chamber contains a gas that is moveable within the gas chamber in response to wave-like motion of the first panel. Movement of the gas increases the effective acoustic mass of the boom attenuation panel, and damped the wave-like motion of the first panel, which operates to reduce noise generated from the wave-like motion of the first panel.

Abstract: Methods and vehicles are provided for providing haptic feedback to a vehicle occupant. In one embodiment, the method includes selecting a pattern of active haptic periods during which a controller will command a plurality of haptic actuators disposed in a seat of a vehicle to generate haptic pulses, determining a desired voltage of a signal supplied to the haptic actuators that indicates the active haptic periods to generate a desired intensity of haptic pulses, determining an actual voltage of an energy storage device of the vehicle, calculating a pulse width modulation (PWM) pattern that simulates the desired voltage when applied to the signal using the actual voltage, and generating a signal that indicates the active haptic periods based on the PWM pattern to command the haptic actuators to generate the desired intensity of haptic pulses.

Abstract: Methods and vehicles are provided for providing haptic feedback to a vehicle occupant. In one embodiment, the method includes evaluating conditions related to a vehicle, selecting a type of haptic alert based on the evaluated conditions, selecting a pattern of haptic actuators to command based on the type of haptic alert and a location of the haptic actuators in a seat of the vehicle, selecting a number of active haptic periods to command based on the type of haptic alert, selecting a duration of the active haptic periods and a duration of inactive haptic periods based on the type of haptic alert, and generating a signal indicating the active haptic periods based on the selected pattern of haptic actuators, the selected number of active haptic periods, and the selected duration of the active and inactive haptic periods.
