Title: Misfire detector of internal combustion engine
Inventor: HISHIDA TAKUYA
IPC: F01N3/023
Filed: 2018-04-11
Abstract: To enhance detection accuracy of occurrence of misfire at a level that impairs an exhaust emission control function of a filter.SOLUTION: An misfire detector of an internal combustion engine detects occurrence of misfire (OT misfire) at a level that impairs an exhaust emission control function of a catalyst. When detecting the occurrence of the OT misfire, a basic OT misfire rate is multiplied by a correction coefficient depending to a PM accumulation amount. The basic OT misfire rate is a basic value of the OT misfire rate set based on the operating state of an engine. The correction coefficient takes a smaller value as the PM accumulation amount increases. Therefore, the value of the OT misfire rate after multiplication becomes smaller as the PM accumulation amount increases. Therefore, it is possible to detect with high probability that the OT misfire has occurred due to PM combustion at the time of the occurrence of the misfire.SELECTED DRAWING: Figure 2

Filed: 2018-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting a change of severity concerning the symptom of the respiratory insufficiency (RI) or the chronic obstructive pulmonary disease (COPD) of a patient in a device and a system.SOLUTION: A detection monitoring device determines one or more severity change indicators, based on the other measurement value capable of being displayed, the value that is determined by a measurement value of supply pressure or a device. This supply pressure can optionally determine during pressure therapeutic for satisfying an object ventilation volume. These supply pressure or data capable of being displayed can be compared with one or more thresholds selected to display the change (e.g., aggravation in a past symptom) in the symptom of a patient of RI or COPD. The result of comparison enables generation of one or multiple warning or messages in order to inform a patient or a doctor of an imminent change to the symptom of the patient's RI or COPD. Thereby, the patient can find medical consideration for treating this symptom more quickly.SELECTED DRAWING: Figure 1
