Title: Detection for set revolutions of engine
Inventor: OKUDA JIYUNJI
IPC: G01P3/44
Filed: 1984-06-13
Abstract: PURPOSE:To enable accurate detection of set revolutions of an engine, by detecting the continuity of the constant revolutions of the engine over a certain time when a grip sensor on an operation lever fails to detect. CONSTITUTION:Grip sensors 11 and 21 output to a NOR circuit 30 the detection signal indicating whether a finger is off operation levers 10 and 20 and the circuit 30 outputs a signal ''1'' to an AND circuit 40 when two input signals are both ''0''. On the other hand, a rotation sensor 50 detects the revolutions of an engine to be outputted to a microcomputer 100 and a circuit 71, whose signal is outputted to circuits 60, 72 and 73 and a signal ''1'' is outputted when variations are within a fine range. Outputs of the circuits 30 and 75 and a switch 01 are inputted into the circuit 40, whose output turns to ''1'' when the outputs are all ''1'' and applied to a timer 80 and an inverter 90. As the timer 80 outputs the signal ''1'' to a latch 60 through a generator 81 as the counted time exceeds a fixed value and the latch 60 latches and outputs the engine rotation signal of the circuit 71 to the microcomputer 100 thereby always transmitting the newest signal.

Filed: 1995-05-19
Abstract: PURPOSE: To minimize the number of states by efficiently calculating prime compatible without judging the mutual inclusive property of class sets being the set of the state set of a finite state machine. CONSTITUTION: An arithmetic processor 12 executes a program stored in a program storage device 14, generates the solution set of prime compatible in a data storage device 13 and minimizes the number of states to output from an input/output device 11 after then. A merger table preparing program 15 prepares a merger table from a state transition table and a maximal compatible generating program 16 prepares maximal compatible from the merger table. A signature generating program 17 generates a signature being the partial set of given maximal compatible and a compatible generating program 18 generates the partial set to be the candidate for prime compatible. A compatible to be controlled excluding program 19 investigates the inclusive relation between the candidate for compatible and the signature to exclude compatible to be controlled.  It is easy to investigate the mutual inclusive relation between partial sets, so that time for calculation is reduced.

Title: Apparatus and method for correcting positioning data
Inventor: ISHIGURO MOTOKI
IPC: G01C21/00
Filed: 1995-05-19
Abstract: PURPOSE: To reduce influences when a position-measuring position changes relatively large and quickly converge to a correct position-measuring position, by sequentially estimating a next position-measuring position based on a moving direction and a moving speed at a determined position-measuring position. CONSTITUTION: At the first determination, a system controller determines a position-measuring position m1 based on measured data by a GPS. Then, an estimated shift V0 of an initially determined position d0 to the position m1 is set from a moving speed and a moving direction of one's own vehicle, and also an estimation range A0 is set. When the position m1 is compared with the estimation range A0 and detected to be included in the estimation range A0, a position d1 obtained by adding a vector from a position m0 to the position m1 to the position d0 is set as a determined position-measuring position. If a second position-measuring position m2 is not included in an estimation range A1 by influences of multipaths, a position d2 obtained by adding an estimated shift V1 to the position d1 is set as the determined position.  Positions d3, d4 are sequentially obtained afterwards by adding estimated shifts V2, V3 respectively.

Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a preceding car detective alarm system that is checking the frequency of preceding car capturing definitions, and capable of preventing any false alarm after the capturing definition in particular. SOLUTION: In a preceding car detective alarm system, a reflected signal from a light pulse irradiation receiver 2, a brake signal from a foot brake switch 4 and a speed signal from a tachometer 10 are all inputted into an arithmetic and control unit 1 which detects any approach to a preceding car from a variation in the speed signal, and judges a capturing definition of the preceding car from a level of the reflected signal, thereby emitting a first alarm. After the capturing definition, if there is an approach to the preceding car due to a creeping phenomenon, it judges it by means of a periodic variation in the speed signal or a level increase in the reflected signal, emitting a second alarm. In this case, however, it is produced by way of running after the start of the preceding car, this second alarm is not emitted at all.  In the case of being unaware of the start of the preceding car after the capture definition, it is judged by a level phenomenon of the reflected signal, emitting a third alarm.
