A resonator for damping pressure waves or instabilities in a system supported by acoustic energy wherein the resonator adopts the use of counter-bored openings on the downstream side of the resonator within the flow path of the system. Each transmission apparatus includes a data input processing unit to which data is input, a first controller that performs a control process for transmitting the data, and a first wireless communication processing unit that transmits the data to the reception apparatus according to the control process performed by the first controller. An additional step of assembling the upper panel of shoe sole on the partially vulcanized rubber sheet is also performed. Further, the processor may be configured to select a technique for each domain interval based on the cost indicators; and provide for configuring an application processor to solve the function via the selected techniques and the respective domain intervals. Geometric shapes of the part and opening may be substantially the same or different, as long as there are at least two points of contact for frictional engagement. The label includes a pattern that is associated with the function so that detection of the pattern identifies the function.
