A tracing device and a tracing method for realizing a real-time trace of a moving object such as a person from a time-varying image by method of a light processing load, and for learning features through the trace thereby to realize a trace of higher precision. The tracing device divides time-varying data inputted into partial images (in a strip or rectangle shape), and compares the background image containing no tracing object thereby with the current image thereby to extract the divided image having the tracing object. In order to discriminate the tracing object, moreover, the tracing device calculates the color high-level local self-correlated data, from which the features of color and shape can be extracted all at once, and performs the discrimination on the basis of a distance from the featuring data of the tracing object registered. The tracing device updates the background image and the registered featuring data into the latest ones. The features are acquired while tracing the tracing object, and the object is discriminated by utilizing the features so that a strong and highly precise trace can be realized.

A circuit for generating a discrimination voltage level V.sub.ref which is used as a reference voltage to discriminate between two adjacent logic levels or an input signal which can have a plurality of different voltage levels generally corresponding to a plurality of respective, different logic levels. The frequency at which the levels of the input signals lie in the upper half of the vicinity (i.e., the voltage range from the level V.sub.ref -.DELTA.V to the level V.sub.ref +.DELTA.V) of the discrimination voltage level (i.e., the "upper half" thereof being the voltage range from V.sub.ref to V.sub.ref +.DELTA.V, ".DELTA.V" being a predetermined off-set value) and the frequency at which the levels of the input signals lie in the lower half of the vicinity (i.e., as above defined) of the discrimination level (i.e., the "low half" thereof being the voltage range from V.sub.ref -.DELTA.V to V.sub.ref) are compared, and the discrimination level is controlled so that the above two frequencies are the same.

A catalyst for purifying exhaust gases includes a substrate, and a catalytic layer. The catalytic layer includes a lower catalytic layer, a first upper catalytic layer, and a second upper catalytic layer. The lower catalytic layer being loaded with Pd and/or Pt is formed on the substrate. The first upper catalytic layer being loaded with Pd covers an upstream side of the lower catalytic layer, and exhibits a concentration of loaded Pd that falls in a range of from 4.5 to 12% by mass when the entirety of the first upper catalytic layer is taken as 100% by mass. The second upper catalytic layer being loaded with Rh covers a downstream side of the lower catalytic layer.

An object of the present invention is to provide an exhaust gas purifying apparatus for an internal combustion engine which can successfully achieve a good balance between reduction of exhaust emission and removal of particulate matter PM. An upstream side three-way catalyst 18 without OSC materials is disposed in an exhaust pipe 14 immediately below an exhaust manifold 12 of an internal combustion engine 10. A particulate filter (PM filter) 20 for trapping the particulate matter PM contained in exhaust gas is disposed at a downstream side of the upstream side three-way catalyst 18. A downstream side three-way catalyst 22 with the OSC materials is disposed at a downstream side of the PM filter 20.
摘要:
Using a switching signal from a coarse/fine switching and operation mode switching circuit, the width of change of a counter control value during power up is increased, and the width of change is reduced once a steady state is reached. In the steady state, the frequency of updating is limited by a control signal from an update permit control circuit. In the steady state, the frequency band of a current source in an LD driving circuit is reduced in width.
