Abstract: A valve assembly having a housing, and a valve portion disposed in the housing, where the valve is able to change between an open position and a closed position. The valve assembly also includes a variable pneumatic device disposed in the housing, which is able to change between a first configuration and a second configuration, and an inner cavity in fluid communication with the housing. An exhaust aperture is formed as part of the housing, and as pressure builds in the variable pneumatic device, the variable pneumatic device changes from the first configuration to the second configuration such that air is prevented from flowing around the variable pneumatic device, and air flowing through the valve body passes through the exhaust aperture.

Abstract: A safety system for motorcycle comprises at least one sensor mounted to the motorcycle to sense a feature of an environment surrounding the vehicle. An electronic control unit is configured to receive a signal from the at least one sensor and determine a probability that a safety incident may occur based upon the at least one feature. The probability is compared to at least a first threshold and the electronic control unit is configured to send at least one indicator signal when the at least one feature is above the first threshold. The indicator signal may be displayed on a helmet display. The safety system may be one of blind spot detection, forward collision alert, rear collision alert, cross-traffic alert, merging-traffic alert, lane departure warning, and traffic sign recognition.
