Abstract:
PURPOSE: A touch processing device in a portable terminal including a touch screen and a method thereof are provided to improve a reaction speed to touch input, to reduce errors of touch input, and to reduce loads of a storage unit. CONSTITUTION: If the touch input of a user is generated, a process filtering a touch input value of the user is included by using one or more digital filters(405). A touch compensation value is generated by the touch input value(407). The touch input value of the user is compensated by using the touch compensation value(409). [Reference numerals] (401) Is touch inputted?; (403) Confirm an inputted value; (405) Filter the inputted value using a digital filter; (407) Generate a compensation value; (409) Compensate the inputted value with the compensation value; (AA) Start; (BB) No; (CC) Yes; (DD) End
Abstract:
A power wire communication device and a refrigerator having the same are provided to transmit communication data signals via a power wire together with DC power without using any additional communication lines. A power wire communication device includes a DC power generating part mounted in a main body for generating DC power, a power line(320) for supplying the DC power from the main body to an auxiliary unit, a data generating part(330) for generating data for the communication between the main body and the auxiliary unit, a modulation part(340) for modulating the data to transmit the same via the power line together with the DC power, and a demodulation part(350) for extracting the data from an added signal of the DC power and the data.
Abstract:
PURPOSE: A self-diagnostic apparatus for an electric device and a method thereof are provided to perform monitoring during operation of a load and at a mass production line and also during after-service. CONSTITUTION: A self-diagnostic apparatus (106) of an electric device includes a current measurement unit (112) and a control unit (110). The current measurement unit measures current amount supplied to a load during operation of the load. The control unit measures power consumption during the operation of the load on the ground of the current amount measured through the current sensor. The control unit calculates the amount of power consumption change by comparing the power consumption during the operation of the load with rated power consumption of the load. If the amount of power consumption change deviates from the pre-established range, the control unit judges generation of abnormal power in the load.
