摘要： A multiple power mode amplifier includes: N amplifiers connected in series via switches; and a control circuit for controlling the N amplifiers in accordance with the output modes. P amplifiers out of the N amplifiers constitute a driver amplifier, and constitute a negative feedback amplifier including a feedback circuit for negatively feeding back its own output signal to its own input side. N−P amplifiers constitute a final stage amplifier connected in series to the negative feedback amplifier in a disconnectable manner. The control circuit is configured to: in a first output mode, disconnect the final stage amplifier from the negative feedback amplifier, and disable the feedback circuit; and in a second output mode, connect the final stage amplifier in series to the negative feedback amplifier, and enable the feedback circuit.

摘要： An inattentive state determination device includes an observed amount acquiring means for acquiring information on the driver's line of sight and at least one of either information on driving operations or information on the traveling state as an observed amount; and an inattentive state determining means for determining the inattentive state of the driver based on the stochastic relationship between the inattentive state and the observed amount as well as the observed amount acquired by using the observed amount acquiring means. In addition, the inattentive state determining means calculates the probability that the driver is driving inattentively and determines that the driver is driving inattentively when the calculated probability exceeds a threshold.
