Abstract: A dynamic feedback bias circuit. A system utilizing the dynamic bias circuit includes a first bus agent and a second bus agent. The first bus agent generates a first signal having a first voltage swing. The second bus agent has a core which operates at a core operating voltage, the core operating voltage having an amplitude less than the first voltage swing. The second bus agent has an input device which receives the first signal from the first bus agent. The input device of the second bus agent is biased by the dynamic feedback bias circuit to provide a core signal with a voltage swing approximately equal to or less than the core operating voltage.

Abstract: A method of correcting drift in a sensor includes the step of identifying a calibration command. A nominal zero pressure sensor drift correction factor for the sensor is identified by relying upon a calibration voltage value and a calibration temperature value secured at a nominal zero pressure condition. Sensor output is subsequently adjusted according to the nominal zero pressure sensor drift correction factor.

Abstract: An apparatus for mounting micromechanical fluid control components includes a manifold interface plate adaptable for connection to a manifold substrate oriented in a horizontal plane. The manifold interface plate receives mounting stress forces from the manifold substrate along the horizontal plane. An orthogonal component plate is connected to the manifold interface plate in a vertical plane with respect to the horizontal plane of the manifold substrate. The orthogonal component plate includes an orthogonal mounting surface with a micromechanical fluid control component mounted on it. The position of the micromechanical fluid control component on the orthogonal mounting surface substantially isolates the micromechanical fluid control component from the mounting stress forces.
