Physical quantity detection apparatus and inspection method of physical quantity detection apparatus
Patent number: 9127966Abstract: A physical quantity detection apparatus includes a signal output section, a correction value calculation section, and a processing section. The signal output section outputs signals in accordance with a change in physical quantity of a detected object. The correction value calculation section calculates a correction value. The processing section corrects values based on actual output values of the signal output section with the correction value, calculates physical quantities of the detected object based on corrected values, and outputs calculated physical quantities. The correction value calculation section calculates the correction value based on primary error amounts that are differences between post-interpolation actual output values calculated by executing a linear function interpolation process to the values based on the actual output values within a predetermined physical quantity range and the values based on the actual output values corresponding to the post-interpolation actual output values.Type: GrantFiled: July 11, 2012Date of Patent: September 8, 2015Assignee: DENSO CORPORATIONInventors: Tetsuya Hara, Takamitsu Kubota -
Patent number: 9129067Abstract: In a position detector for detecting a position of a detection body, a signal processing circuit processes a signal outputted from a magnetic field detection element. A first storage circuit stores the signal outputted from the magnetic field detection element and outputs a signal to an external device through an output circuit in a normal operation mode. A second storage circuit stores an output value of the first storage circuit. When a malfunction determination circuit determines an instantaneous power interruption mode, a signal route changing circuit prevents a signal transmission between the first storage circuit and the second storage circuit and a signal transmission between the first storage circuit and the output circuit, prevents the second storage circuit from updating data for a certain period of time, and permits the second storage circuit in which updating is prevented to output a signal to the output circuit.Type: GrantFiled: November 21, 2012Date of Patent: September 8, 2015Assignee: DENSO CORPORATIONInventors: Takamitsu Kubota, Tohru Shimizu, Tetsuya Hara, Yoshiyuki Kono
