An automatic voice response section transfers voice input from a caller to a voice recognition section, and the voice recognition section generates a voice recognition result. The method of this embodiment provides determining a flow context associated with a receive packet; and if the flow context complies with a dynamic interrupt moderation policy having one or more rules, generating an interrupt to process the receive packet substantially independently of an interrupt generated in accordance with an interrupt coalescing scheme. The thermal conductivity enhancing material improves the heat dissipating characteristics of the die during operation and testing and helps to reduce or prevent overheating. The proximal end is attached to the first transducer so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip attached to the distal end. The input voltage detecting circuit detects the input DC voltage and when it is detected that the input voltage value may possibly cause malfunction, a control circuit turns off a switch circuit based on the detection output, whereby power supply from the power supply circuit to a transmission circuit is stopped, and malfunction of the transmission circuit is prevented. The present invention allows for the correlation of a physical circuit description and a logical circuit description, which can also be viewed as correlating one or more of the physical elements of the design’s implementation in the PLD with one or more of the design’s logical elements.
