    摘要： An electronic device for generating an activation signal in response to detection of an acoustic signal having parameters within respective predetermined ranges, and then automatically dialing a prestored telephone number and transmitting a prerecorded message over the telephone line in response to the activation signal. The device includes a transducer for transducing an acoustic signal into an electrical signal; a detector for outputting an activation signal in response to detection of an acoustic signal having parameters within respective predetermined ranges; and a telephone module for automatically dialing a prestored number and transmitting a prerecorded message in response to the activation signal. The detected parameters include the amplitude of the acoustic signal, the frequency of the acoustic signal, the duration of each burst of the acoustic signal, and the duration of each interval between successive bursts of the acoustic signal.

    摘要： A vehicle passenger sensing system and method in which the presence and position of a passenger is determined by transmitting an electric field from a first electrode and measuring currents induced by the electric field in a plurality of receiver electrodes. The induced currents at the various receiver electrodes are then compared to determine the presence of an adult size passenger, to distinguish between front-facing and rear-facing child safety seats, and to detect when a passenger is out of position. A switching circuit is provided to selectively transmit the electric field from each of the plurality of electrodes.
