  • Patent number: 11067304
    Abstract: An air-conditioning apparatus enables a user to recognize both a leakage of refrigerant and an abnormal condition when a refrigerant leakage condition and the abnormal condition have occurred. When a condition in which a leakage of refrigerant is detected and a condition in which an abnormality is detected have occurred together, the refrigerant leakage condition and the abnormal condition are displayed together on a display part. Consequently, when the condition in which the leakage of refrigerant is detected and the condition in which the abnormality is detected have occurred, the user is allowed to recognize the leakage of refrigerant and the abnormal condition at once.

  • Publication number: 20210215485
    Abstract: In a locator device, a dead reckoning part calculates a position of a subject vehicle by dead reckoning. A pseudorange smoothing part smooths a pseudorange between a GNSS satellite and a position of the subject vehicle using a carrier wave phase of the GNSS satellite. A GNSS receiver positioning error evaluation part evaluates reliability of the position of the subject vehicle calculated by the multi-GNSS receiver. A GNSS positioning part (KF method) calculates a position of the subject vehicle from a smoothed value of the pseudorange, a positioning augmentation signal, and an orbit of the GNSS satellite. A complex positioning part (KF method) calculates an error in the dead reckoning from the position of the subject vehicle calculated by the GNSS positioning part (KF method), and corrects the position of the subject vehicle calculated by the dead reckoning part based on the error in the dead reckoning.
