Abstract: A low cost high side supply shut down circuit that operates to deactivate the power supply of a central supply, such as to pressure regulators, solenoid valves, etc., as parts of non-repairable electro-hydraulic transmission modules in the event of a malfunction, e.g. a low side driver circuit failure. The supply voltage is connected to the high side of a fuse. The load circuits receive power or no power depending on the operating condition of the fuse. Coupled across the fuse is a fuse trigger status detection circuit as part of a diagnostics and control module. The diagnostics and control module is connected to the input of a shut down low side output driver circuit. The attached low side loads have individual detection circuits that are coupled to the diagnostics and control module as well as their enable inputs.

Abstract: A method and apparatus for adjusting the impact of an airbag on an occupant. The apparatus includes a programmable controller programmed to generate a control signal based on information from a pressure sensor located within an inflation structure. The programmable controller is coupled in data communication to a gas flow generator and controller. The gas flow generator and controller has a valve to control the direction of gas flow into the inflation structure based on the control signal from the programmable controller. The programmable controller is programmed to continuously monitor the output signal of the pressure sensor and adjust the control signal based on the output signal of the pressure sensor. In one embodiment, the control signal is a pulse-width modulated signal and the valve is controlled such that inflation of various parts of the air bag is adjusted to control the severity of the impact of the air bag on the occupant.
