Abstract: A method for secure data transmission in wireless sensor network includes that: the network user determines a master key and inputs it into a central node and a device node; after the central node and the device node have authorized each other, the central node generates a new session key and sends it to the device node; while the central node and the device node communicate with each other, the data sending party uses the new session key to encrypt the data for transmission and verify the integrity of the data, and the data receiving party uses the session key to decrypt the data and verify the integrity of the data.

Abstract: An improved process 30 for making an engine poppet valve 10 provides an unfinished poppet valve 10 with an initial diameter (d1) of a valve head 22 and an initial thickness (t1) of an interface 56 between a seat facing groove 54 and a combustion face 18 of the valve 50 prior to seat facing the valve 50 to prevent burn-through during the welding process 38. Coining 40 the valve head 22 after seat facing 38 decreases the initial thickness (t1) of the interface 56 to a selected thickness (t2) and increases the initial diameter (d1) to a final or desired diameter (d2) of the valve head 22. The method of the present invention eliminates any need for removing excess material and allows for hot forming the seat facing material 58 to reduce machining steps.
