摘要： A configuration for measuring the position and the orientation specific to a mixed reality is separated from an application 70 to operate independently, and a shared memory 60 or process-to-process communication is used for data communication between them. This allows to modify configuration associated with the measurement of the position and the orientation such as the type of the sensor or an alignment method without modifying or recompiling the application 70. This facilitates providing the mixed reality system and supporting system modification.

摘要： The engine misfire detection apparatus of the invention successively determines whether a rotational fluctuation difference Nxd360 as a difference between a rotational fluctuation Nxd at a certain crank angle CA of an engine and a rotational fluctuation Nxd at a 360 degree-prior crank angle CA exceeds a predetermined reference value A1 (step S150) and whether a rotational fluctuation difference Nxd720 as a difference between the rotational fluctuation Nxd at the certain crank angle CA and a rotational fluctuation Nxd at a 720 degree-prior crank angle CA exceeds a predetermined reference value B1 (step S160). The engine misfire detection apparatus detects a misfire of the engine upon satisfaction of all conditions regarding rotational fluctuation difference proportions Nja2, Nja3, and Nja4 on the basis of the rotational fluctuation difference Nxd360 (step S200) and all conditions regarding rotational fluctuation difference proportions Njb2, Njb3, and Njb4 on the basis of the rotational fluctuation difference Nxd720 (step S210), when both the rotational fluctuation differences Nxd360 and Nxd720 exceed the respective reference values A1 and B1 (steps S150 and S160). This arrangement ensures adequate and accurate detection of an engine misfire during warm-up of a catalyst included in an exhaust emission control unit with a significant delay of the ignition timing in the engine.

摘要： An air-fuel ratio control apparatus of an internal combustion engine according to the present invention is provided with an oxygen storage amount estimator for estimating an oxygen storage amount of an exhaust purifying catalyst and air-fuel ratio control means for controlling an air-fuel ratio, based on the oxygen storage amount. An upper threshold and a lower threshold are set for the oxygen storage amount, and the air-fuel ratio controller performs such control that, when the oxygen storage amount is larger than the upper threshold, the controller controls the air-fuel ratio to a rich region and that, when the oxygen storage amount is smaller than the lower threshold, the controller controls the air-fuel ratio to a lean region. Since this control makes the oxygen storage amount vary between the upper threshold and the lower threshold (within a predetermined range), it is feasible to promote activation of the exhaust purifying catalyst, so as to keep purification performance of the exhaust purifying catalyst high, and to implement stable control of air-fuel ratio.

摘要： A control apparatus for an internal combustion engine is provided which performs intake air flow control for controlling an engine speed to a target engine speed during starting of the engine, by adjusting a throttle opening depending upon the engine speed. The control apparatus judges a degree of deterioration of a combustion state in the engine, based on a difference between a predetermined reference peak engine speed and an actual peak engine speed, and switches from the intake air flow control to ignition timing control for controlling the engine speed when the engine operates in a poor combustion state, at a point of time that is determined based on the degree of deterioration of the combustion state.
