摘要:
A method of making flower-shaped bath scrubber uses a bar as the support to pierce through a netting band which is folded at one end, then use the bar as an axis to have the remaining netting band run through one end of the bar. Then move the netting band laterally along the bar to another end and have the remaining netting band run through the bar from another end. The foregoing process is repeatedly performed until the netting band is completely disposed on the bar. Then fasten one end of the netting band and remove the bar. The wound around netting band then may be unfolded and stretched to form a shape desired. After another fastening, a flower-shaped netting bath scrubber will be formed.

摘要:
In a capacitance sensing analog circuit of a touch panel sensing circuit, by raising a magnitude of a current flowing through a sensing capacitor to form an amplified sensing capacitance, while sensing the amplified sensing capacitance with the aid of pulse width modulation signals, higher resolution of the original sensing capacitance may thus be achieved. Besides, by using a self-calibrating capacitance sensing circuit on the touch panel sensing circuit, linear errors and DC errors of an output signal of the capacitance sensing analog circuit may be filtered off, and thereby resolution of a capacitance amplifying ratio may be effectively raised so as to relieve errors within the capacitance amplifying ratio caused by noises.
