摘要:
In general, the multi-mode analog front-end provides an internal line driver and hybrid, as well as numerous functions, in order to provide a close to optimum solution for all digital subscriber line applications. The functions provided for by the analog front-end include; programmable hybrid attenuation; onboard amplifiers for driving external transmit and receive filters; a line driver with programmable drive and gain; programmable RC-filters capable of calibration via an internal loop-back under digital control; a programmable switched-capacitor filter for tracking the over sampling rate used by a digital signal processor; internal testing functions; a high frequency boost circuit; a dual input peak detector; selectable data rates; and a programmable data interface. The analog front-end allows for use of particular blocks within the analog front-end particular to the functions necessary to compensate for a particular digital subscriber line application.

The present invention discloses a method for supporting extended parameter(s) in a REFER message, applied in a system comprising a parameter proxy server that can receive and forward the REFER message; upon receiving the REFER message including the extended parameter(s), the parameter proxy server performing the following processing: storing said extended parameter(s); sending the REFER message to the indicated party of the message; upon receiving a third party message sent by said indicated party and indicated by the method parameter in the REFER message, adding the extended parameter(s) stored into the third party message; sending the third party message to said third party. With the present invention, those IMS intelligent terminals that do not support the extended parameter(s) in the REFER message can more fully utilize the REFER message to use the abundant services provided by NGN.
摘要:
Methods and apparatus for drying ceramic green bodies include providing one or more ceramic green bodies in a microwave heating chamber operatively connected to a microwave source and a PLC. The total mass of the ceramic green bodies present in the microwave heating chamber is determined. Microwave energy is generated with the microwave source and transmitted from the microwave source to the microwave heating chamber. A transmitted power of the microwave energy transmitted from the microwave source to the microwave heating chamber is measured with power sensors. The reflected power of reflected microwave energy reflected back from the microwave heating chamber is also measured. The power of the microwave energy transmitted from the microwave source to the microwave heating chamber is adjusted based on the total mass of ceramic green bodies present in the microwave heating chamber, the measured transmitted power and the measured reflected power.

An adjustable hydraulic horizontal jack including a frame, a hydraulic unit, a jib unit, link rods, and a handle. Here, the structures of the jib and the link rod(s) are improved according to an embodiment. With the improved structures, the jack has rational structures and can act reliably. In addition, under the parameters equivalent to those of conventional hydraulic horizontal jacks, the jack of an embodiment of the present invention can change the height of the lowest position and the load by adjusting the length of the jib and link rods. Therefore, the jack is adapted to jacking up not only a light automobile with a low chassis but also a heavy automobile with a high chassis, thus having a wider scope of application.
