Abstract:
The present invention provides a method for calculating a destruction rate of refrigerant by establishing a calibration line using standard refrigerant gases and measuring the amount of refrigerant remaining in exhaust gas discharged after destruction of waste refrigerant. For this purpose, the present invention provides a method for calculating a destruction rate of refrigerant, the method including: establishing a calibration line using standard refrigerant gas samples whose concentrations are known; sampling exhaust gas finally discharged after decomposition of waste refrigerant; measuring the concentration of refrigerant remaining in the sampled exhaust gas; and calculating the amount of undestroyed refrigerant using the concentration of refrigerant remaining in the exhaust gas, the amount of exhaust gas discharged, and the known density of refrigerant.
Abstract:
Provided are a pointing apparatus capable of providing haptic feedback, and a haptic interaction system and method using the same. The pointing apparatus includes a wireless communication unit, a controller, and a haptic stimulator. The wireless communication unit receives an event including haptic output information through wireless communication with the outside. The controller generates a control signal for reproducing a haptic pattern corresponding to the haptic output information. The haptic stimulator reproduces the haptic pattern by means of the control signal. Thus, it is possible to increase the performance and usability of a user interface of a user terminal including a touch screen.
