Abstract: A system for calibrating signals received over a power line within a vehicle includes a signal conditioning circuit that converts the analog input signals into digital input signals. In one embodiment the circuit includes an adjustable gain circuit that outputs an amplifier gain signal establishing an amplifier gain level and an amplifier that outputs amplified signals responsive to the analog input signals and the amplifier gain signal. In another embodiment, the circuit includes a bias circuit that outputs a bias signal establishing a bias level and a comparator that generates the digital input signals responsive to the analog input signals and the bias signal. A controller receives the digital input signals and generates, depending on the embodiment, one or more control signals configured to control the configuration of the amplifier gain signal and amplifier gain level and/or the bias signal and the bias level.

Abstract: A braking system for an air brake vehicle includes a source of working pressure and a source of vacuum pressure. The system includes at least one brake actuator having a first chamber for receiving the working pressure, a second chamber for receiving the vacuum pressure; and a push rod that moves linearly in response to pressure in the first chamber and second chamber. A brake assembly is mechanically connected to the push rod for applying friction to a wheel end of a vehicle in response to the linear movement of the push rod.
