摘要： A system and method for controlling an engine to regulate the oxygen storage level in an emission control device are provided. The system includes oxygen sensors disposed in an exhaust gas stream of the engine upstream and downstream of the emission control device. The oxygen sensors generate a feedgas and tailpipe air fuel signals. The system includes an electronic control unit (ECU) configured to obtain an adjusted feedgas air fuel ratio responsive to the feedgas and tailpipe air fuel signals to correct bias in the feedgas air fuel signal. The (ECU) is further configured to obtain an estimate of an oxygen storage level in the emission control device responsive to the adjusted feedgas air fuel ratio and the tailpipe air fuel signal. Finally, the (ECU) is configured to generate a control signal for the engine responsive to the adjusted feedgas air fuel ratio and the oxygen storage level estimate.

摘要： This patent describes a retractor system for surgical applications of the type used to retract organic tissues not involved in an operation, in an area where such an operation is to be performed, of the type comprising at least one spatula equipped with at least one spatula body (1) and a layer of bio-compatible material (20), as a coating adhering to the spatula body (1). Advantageously according to the invention, the retractor system comprises at least one sensor (2, 3, 4, 27), substantially integrated in such a spatula body (1) and at least partially coated with the layer of bio-compatible material (20) to detect characteristic parameters of the organic tissues at a point of contact with the spatula body (1). A detection system (40) using such retractor system is also described.
