摘要： PROBLEM TO BE SOLVED: To accurately detect a turn angle even when an antenna reverses at a position deviated from an expected reversing position in a radar device of a mechanical scanning method. SOLUTION: This signal processor for receiving an angle signal when a turning section reciprocating and turning within a predetermined angle range turns by unit angle comprises a reverse detecting means for detecting the reverse of the turn direction of the turning section based on state transition of the angle signal, and a turn angle detecting means for detecting the turn angle of the turning section based on the angle signal input after detection of the reverse. Based on the angle signal input after a first reverse of the turning section is detected by the reverse detecting means and until a second reverse is detected, the turn angle detecting means corrects the turn angle based on the angle signal input after the second reverse is detected, so that it can detect the turn angle based on the angle signal from the expected reversing position.

摘要： PROBLEM TO BE SOLVED: To restrain a malfunction caused by a disturbance factor in detecting an intrusion in a vehicle and to normally detect an intruder whatever pattern the output waveform pattern of a sensor is. SOLUTION: In this in-vehicle intrusion detector 100, a peak difference computing section 101a of a control circuit 101 computes the difference between two peak values (n-1), V(n) whose input times adjoin out of the peak values of input signals, and a peak-to-peak time clocking section 101b clocks the time difference ΔT of the output times of V(n-1), V(n). A peak output estimate value computing section 101c computes an estimate value V e (n) of V(n) corresponding to V(n-1) and the time difference ΔT. A shock wave determining section 101d determines the detection of shock wave when the difference between V(n) and V e (n) is within a predetermined range only the predetermined intermittent number of times. When the shock wave is determined by the shock wave determining section 101d, an intrusion detection processing section 101e cancels intrusion detection processing of the intruder into the vehicle.

摘要： PROBLEM TO BE SOLVED: To provide a data processor capable of preventing malfunction, even when external noise level, having a steep rise with a fixed period, temporarily goes down. SOLUTION: When the rise time of input waveform, having different period, is short, following five conditions are determined continuously: (1) 450 ms has not elapsed, after the output voltage of a sensor becomes 0.45 V or above, (2) number of the crests of input waveform is 7 or higher, (3) in a state that sensor signal is being generated, (4) maximum value of period difference for the past 7 crests is 10 ms or shorter, (5) peak generating time for the past 7 crests is 25 ms or shorter, and when five conditions are satisfied, the satisfaction is held for inhibiting the data processing, based on the sensor output. Meanwhile, when a rise time to the peak which is not observed for the external noise is generated, namely, when peak generating time for the past 7 crests is 25 ms or longer, the prohibition is canceled and the data processing is executed.

摘要： PROBLEM TO BE SOLVED: To provide a data processing apparatus which can simply prevent malfunction when high frequency noise is input without accelerating a sampling frequency of an A/D converter. SOLUTION: After a sampling value Sn from the A/D converter is stored, it is compared with a peak value Sp. When it is larger than the peak value Sp, the peak value Sp is updated. When the sampling value Sn is smaller than the peak value Sp, and when the sampling value Sn is smaller than offset value (OV) and the peak value Sp is larger than (0.1V), a flag is set in a storage area of a memory storing the sampling value Sn of the peak value Sp. Then, when it is judged that the number of flags in a fixed period is larger than 4, it is judged that high frequency noise is contained, and judgment by a data processing part is prohibited.
