Abstract: A car door warning system includes a sensing unit, a control unit and a warning unit. The sensing unit is disposed at a door handle of at least one car door. When the door handle is approached or touched by an object, the sensing unit generates a sensing signal before the door handle is moved. The control unit receives the sensing signal and generates a control signal. The warning unit receives the control signal and generates a warning signal. The car door warning system can send out a warning signal in advance before the door handle is moved or before the car door is opened, and can prevent accidents while the car door is opened.

Abstract: A hot water system includes cold water pipes, hot water pipes, a water heater, a pump, a pump control unit and a connection valve unit. The pump is used to increase the pressure of the hot water pipes to a preset higher level than the pressure in the cold water pipes. When hot water is needed, the connection valve unit at the user side is opened to connect the cold water pipes and the hot water pipes, and when the cold water pipes and the hot water pipes are connected, the water pressure difference between them will become smaller. When the pressure difference change is detected, the pump control unit will activate the pump to pump the water in the hot water pipes into the cold water pipes, so the water in the pipes starts to circulate, and the water will flow through the water heater and will be heated. When the heated hot water reaches the user, the pump is stopped. After the hot water is being served or when the water temperature drops down, the pump is again put into normal operation.

Abstract: A lock includes a combination code device, a pin, and at least one fixing unit. The combination code device has a plurality of code input units. When the code combination of the code input units is different from a preset combination, the lock is in a locked state, so the pin is engaged with the combination code device and cannot be moved or rotated.

When the fixing unit is at a first position, the code combination of the code input units can be changed; when it is at a second position, it fixes at least one code input unit, and at least part of the code combination of the code input units can not be changed.

Abstract: A touch-control method of an LCD is provided. During the idling time in-between the writing periods, the first touch-position sensing step detects the values of liquid crystal capacitances formed between the scan lines and the counter electrode, and detects a scan-line-direction touch position (Y) according to the values of the liquid crystal capacitances formed between the scan lines and the counter electrode. The charging step charges a voltage signal into each of the data lines needed to be detected after the scan-line-direction touch position (Y) is detected. After the voltage signal is charged, the second touch-position sensing step detects the values of liquid crystal capacitance formed between the data lines and the counter electrode, and detects a data-line-direction touch position (X) according to the values of the liquid crystal capacitance formed between the data lines and the counter electrode.
