the first speed and which generates a first signal representing the first speed; a second sensor which measures the second speed and which generates a second signal representing the second speed; a third sensor which measures a position of the throttle and which generates a third signal representing the throttle position; and a controller which is communicatively coupled to the transfer case, to the first sensor, and to the second sensor, which receives the first, second, and third speeds, which utilizes the first signal and the second signal to calculate a delta shaft speed and which utilizes the delta shaft speed and the third signal to estimate an amount of heat generated by the clutch, the controller being further effective, when operating in the automatic four-wheel drive mode,and first-class hospital due to coughing and hemoptysis. The emergency doctors prescribed antibiotics and hemostatics, which partially relieved the symptoms. However, the disease recurred six months later and the patient was administered the same treatment, which provided some relief. One year after the first hospitalization, the hemoptysis volume had doubled and the patient was transferred to the Renji Hospital. A bronchoscopy was performed at a hospital in Hangzhou (Zhejiang, China). However, the bronchoscopy may have caused airway bleeding, resulting in an obscured visual field and immediate termination of the procedure. In addition, the patient had no significant individual or family history of pulmonary disease. However, the patient's grandmother had succumbed due to colorectal carcinoma a few years prior to this incidence.

Based on the previous diagnosis and information, the
