    摘要： A misfire-detecting system detects a misfire occurring in an internal combustion engine in such a manner that a value of discharge current is detected when sparking voltage is generated in response to an ignition command signal, the detected value of discharge current is compared with a predetermined current value, and it is determined that a misfire has occurred when a time period over which the detected discharge current value after generation of the ignition command signal is above the predetermined current value is shorter than a predetermined time period.

    摘要： A misfire-detecting system for an internal combustion engine detects a value of sparking voltage generated by the igniting device of the engine after generation of an ignition command signal, compares the value of the detected sparking voltage with a predetermined value, and determines whether or not a misfire has occurred in the engine, based upon the result of the comparison. The misfire-detecting system can discriminate between a misfire attributable to the fuel supply system of the engine and one attributable to the ignition system of the engine, from a detected peak value of the sparking voltage.

    摘要： A vehicle entry/tire pressure management system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. Some antennas can also be configured to transmit a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals.

    摘要： A peak factor reduction unit that never allow peak factor reproduction even when interpolation is done in a succeeding stage. The unit detects a local maximum value of amplitude components from an input complex signal and supplies a complex signal that passes a band limiting baseband filter and an interpolation filter to a correction signal generation unit for generating a correction signal used for peak factor reduction and reduces a peak factor of the input complex signal with use of the correction signal generated from an interpolated complex signal.
