Abstract: An electronic device for accessing wireless network includes a radio frequency (RF) module, a power supply management unit, a CPU and a data transmission interface. The RF module receives electromagnetic wave signal from networks and transmits electromagnetic wave signals to the networks. The data transmission interface transmits the electromagnetic wave signals from the RF module to the CPU, and transmits data and commands between the RF module and the CPU. When the electronic device does not communicate with a remote server on the networks during a predetermined time period, the CPU suspends the data transmission interface. A related method of saving resource is also provided.

The present invention adjusts the prosody structure of the text according to the target speech speed. The synthesized speech will have improved quality.

Abstract: A wireless communicating electronic device includes a wireless communication unit, a shell receiving the wireless communicating unit therein, a touch sensing unit, and a processing unit. The touch sensing unit includes an antenna, a regulating circuit, and an analog-digital (AD) converting module. A given portion spatially corresponding to the antenna defined on the shell. The antenna generates an alternating current (AC) signal in response to a finger touch on the given portion. The regulating circuit regulates the AC signal. The AD converting module converts the AC signal into a digital signal. The processing unit executes an instruction in response to the digital signal.

Abstract: The present invention is directed to a method for determining the concentration of hydrogen peroxide in a chemical process stream which may include interfering components. Still further, this invention is directed to a method and apparatus for the on-line, automated determination and control of hydrogen peroxide in a process stream.

Abstract: The present invention is a rapid method of determining the concentration of the major components in a chemical stream. The present invention is also a simple, low cost, device of determining the in-situ concentration of the major components in a chemical stream. In particular, the present invention provides a useful method for simultaneously determining the concentrations of sodium hydroxide, sodium sulfide and sodium carbonate in aqueous kraft pulping liquors through use of an attenuated total reflectance (ATR) tunnel flow cell or optical probe capable of producing a ultraviolet absorbency spectrum over a wavelength of 190 to 300 nm. In addition, the present invention eliminates the need for manual sampling and dilution previously required to generate analyzable samples.
