Abstract: A brake system includes a reservoir and a master cylinder operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. The master cylinder is selectively operable to generate brake actuating pressure at an output for hydraulically actuating a pair of hydraulically actuated wheel brakes in a manual push-through operation. A power transmission unit is configured to selectively generate pressurized hydraulic fluid for actuating the pair of hydraulically actuated wheel brakes. First and second two-position three-way valves are hydraulically connected to respective ones of the pair of hydraulically operated brakes and to both the master cylinder and the power transmission unit. The first and second three-way valves each are configured to selectively switch the respective hydraulically operated brake to receive fluid from a selected one of the master cylinder, in a backup braking mode, and the power transmission unit, in a normal non-failure braking mode.

Abstract: A gas detection device and a process monitor an area for a combustible target gas. A heating segment of a detector (10) is heated when electrical current flows therethrough. A heating segment of a compensator (1) is heated when electrical current flows therethrough. An electrical voltage is applied to both the detector and the compensator. The heating of the detector (10) causes a combustible target gas to be oxidized in an interior of the gas detection device. A detection variable, which depends on the temperature (Temp_10) of the detector, and a detection variable, which depends on the temperature (Temp_11) of the compensator, are measured. A presence and/or a concentration of a target gas are determined as a function of the detection variables. A quality parameter is measured and increases as the detection variable depending on the detector temperature increases and as the detection variable depending on the compensator temperature decreases.
