Abstract
An apparatus for calculating torque of a variable capacity compressor, including: a sensor configured to detect internal and external states of an air conditioner; an OFF-torque calculator configured to calculate and store a steady-state torque according to a state detected by the sensor just before a clutch is turned off; a start torque calculator configured to calculate a start torque according to a state detected by the sensor after the clutch is turned on; a steady-state full-stroke calculator configured to calculate a steady-state full-stroke torque based on an assumption that the compressor was in a full-stroke-state according to a state detected by the sensor after the clutch is turned on; and a determiner configured to provide, when an elapsed time after the clutch is turned on is less than a predetermined time, a maximum one of the torque values calculated by the OFF-torque calculator, start torque calculator, and steady-state full-stroke calculator.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
