    摘要： Techniques are described for detecting a hand gesture made by a user. Fingertips of a hand may be identified and tracked over time. When a user contracts the fingertips from an extended position, hand spread may be calculated based on the area of the hand and fingers. The hand spread over time may be compared to a Gaussian function to evaluate whether the observed motion represents a grasping motion.

    摘要： An example induction system for an engine includes a plenum in fluid communication with multiple primary runners. A plenum valve is arranged between first and second chambers of the plenum, which are respectively in fluid communication with first and second sets of the primary runners. The plenum valve is configured to move between open and closed positions and regulate flow between the first and second chambers. A second runner is arranged upstream from and in fluid communication with the plenum. A runner valve is arranged in the secondary runner and configured to vary the amount of flow through the secondary runner. A common actuator is interconnected to both the plenum and runner valves and is configured to move both of the plenum and runner valves between desired positions to achieve desired valve configurations that tune the engine.

    摘要： An induction system is designed for an engine that includes a manifold having a plenum in fluid communication with primary runners. A plenum valve is arranged between first and second chambers of the plenum that are respectively in fluid communication with first and second sets of the primary runners. The plenum valve is configured to move between open and closed positions to regulate flow between the first and second chambers. A secondary runner is arranged upstream from and in fluid communication with the plenum. The secondary runner includes first and second runner portions with the second runner portion being shorter than the first runner portion. A runner valve is arranged in the secondary runner between the first and second runner portions and is configured to selectively direct flow through the first and second runner portions to the plenum to obtain a desired effective tuning length. Accordingly, the example induction system provides a more effective configuration for tuning an engine that is more simple, cost effective and easier to package.

The steel is cast into a billet, which is heated and hot-rolled to 1150˜1200° C. into a plate at a finish-rolling temperature 830˜900° C. The plate is cooled to a temperature ≧570° C. and cold-roll flattened at compression ratio 2˜5%. The flattened plate is normalized at temperature not below 950° C. for 30˜180s, and then pickled and cold-rolled into a sheet with thickness of the finished product. The sheet is finish-annealed quickly heating the sheet to 800˜1000° C. at temperature rise rate ≧100° C./s, soaking the heated sheet for 5˜60s at the temperature, and then slowly cooling the sheet to 600˜750° C.
