  • Patent number: 11946425
    Abstract: The present invention provides an engine control device that sets a cam signal read value according to a cam signal output from a cam angle sensor, in a front-rear determination position; if the cam signal read value is alternately changed between 1 (LOW) and 2 (HIGH) in the front-rear determination position, sets the cam signal read value to the cam signal expected value; if the cam signal read value is not alternately changed between 1 (LOW) and 2 (HIGH), inverts the cam signal expected value in the control cycle of the previous time, and sets the resultant cam signal expected value; then, when the cam signal read value and the cam signal expected value are equal to each other, distinguishes the cylinders by using the cam signal read value; and when the cam signal read value and the cam signal expected value are different from each other, distinguishes the cylinders by using the cam signal expected value.

  • Publication number: 20040084535
    Abstract: An optical portable cellular phone having a character recognition function is provided which is capable of reducing a rate of character recognition error or a rate of character recognition failure in case of reading a character string. When a character recognizing section judges a captured character to be unrecognizable (misread or unreadable), a data referencing section judges whether or not incorrect character code due to the unrecognizable character corresponds to any one of feature character strings, referring to information about the feature character strings stored in a memory. When it is judged that the incorrect character code corresponds to any one of the feature character strings, a data correcting section corrects in a manner that a form of the incorrect character code matches up with that of the feature character string.
