Abstract: The invention provides a capacitive touching apparatus, which includes at least an equivalent capacitor module, a first comparator, a first reference current generator, a first detection capacitor module and a selection switch module. The equivalent capacitor module receives a periodic driving signal and produces an output voltage according to the driving signal. The first comparator compares the output voltage with a first reference voltage and thereby produces a first comparison result. The first reference current generator produces a first reference current and a second reference current according to a base current, in which the first reference current generator decides whether to respectively output the first reference current and the second reference current according to the first comparison result, and the first reference current is output to the equivalent capacitor module. The first detection capacitor module produces a first detection output signal according to the second reference current.

Abstract: A method is proposed for asynchronously transmitting a serial data comprises steps of: providing a first signal and a second signal, the first signal and the second signal having a state in a first interval; and keeping the state of the first signal and changing the state of the second signal into another state in a second interval for transmitting the serial data.

Abstract: A tire pressure balance apparatus for balancing a left tire with a right tire of a car is proposed. The tire pressure balance apparatus comprises: a first air pumping head for connecting to the left tire; a second air pumping head for connecting to the right tire and stopping an air of the left tire before connecting to the right tire; and a pipe having two sides, the one side connecting to the first air pumping head and the another side connecting to the second air pumping head, a pressure of the left tire and the right tire being balanced after the first air pumping head being connected to the left tire and the second air pumping head being connected to the right tire.
