摘要： In this invention, a valve positioner receives a setpoint from a master and provides a control pressure to a valve actuator for controlling a valve. A sensing circuit in the positioner senses the position of the valve and the control pressure, and a control circuit in the positioner uses both the sensed pressure and position to provide a command output to a pneumatic section which produces the control pressure. In another embodiment of the invention, a positioner receives a setpoint from a master and provides a control pressure to a valve actuator for controlling a valve. A sensing circuit in the positioner senses the valve position and pneumatics in the positioner provide the control pressure as a function of the sensed position and an output from a control circuit within the positioner. The positioner includes a diagnostic circuit which stores a valve attribute and provides a diagnostic output as a function of the stored valve characteristic and a selected one of the sensed variables. In another embodiment of the invention, a positioner includes a correction circuit for storing a valve attribute affected by one of a set of physical parameters and for receiving a selected one of the set of sensed physical parameters. The correction means compensates a command output from a control circuit as a function of the sensed physical parameter and the stored valve characteristic. In another embodiment, the positioner includes a benchset control circuit which ramps the control pressure between an initial control pressure and a final control pressure and back to the initial control pressure, while sampling specific control pressures and their corresponding positions, in order to provide an output indicating the proper spring preload force on an actuator spring.

摘要： A method of electrically isolating a MEMS device is provided. In one example, a piezo-resistive pressure sensor having an exposed silicon region undergoes a Local Oxidation of Silicon (LOCOS) process. An electrically insulating structure is created in the LOCOS process. The insulating structure has a rounded, or curved, interface with the piezo-resistive pressure sensor. The curved interface mitigates stresses associated with exposure to high temperatures and pressures. Additionally, the electrically insulating line may be patterned so that it has curved angles, further mitigating stress.

摘要： A sensor array includes an array of nodes coupled to an optical transmission line. The nodes include a transducer, and encoder, and a transmitter. The transducer senses an environmental condition such as temperature and pressure. The encoder encodes readings from the transducer by means of a characteristic frequency to indicate which node generated the reading. The transmitter transmits the encoded reading to a decoder located near the opening of the oil well, or other blind hole. Power is transmitted to the nodes through the transmission line. A photo-electric converter at the node converts the optical power to electrical energy that is stored to power the node.
