In an embodiment, the device comprises a stainless steel container portion, a stainless steel annular portion, and a silicone mouthpiece portion. A piping space of a recessed shape is formed in the surface of the counter weight facing the engine so as to pass the intake air pipe therethrough. During a design phase of an application, a set of algorithm modules is linked with a calling program to form an initial software program. The arrangement maintains the inter-packet gap despite slight differences between the recovered clock and the system clock.
