摘要:
The invention relates to improved methods of grafting polymer extenders onto porous substrates having diffusive pores, such as those used in protein separations, without filing the diffusive pores of the substrate, and restricting diffusion there through. By changing the grafting conditions and/or monomer composition(s) the resulting porous substrates having polymer extenders grafted thereto have increased protein binding capacity and resin selectivity, thereby enhancing the protein separation effectiveness of the substrate. The grafted polymer extenders provide the substrate with significant binding capacity at higher conductivity. The invention also relates to kits, and methods of using and grafting polymer extenders on porous resin substrates having diffusive pores.

A communication method for use by an input/output (I/O) scanner coupled to a programmable logic controller (PLC) includes coupling at least one I/O module to a backplane, and coupling a maintenance module to the backplane. The communication method also includes selectively enabling and disabling communication between the backplane and the at least one I/O module by actuating a switch in the maintenance module such that network communication is maintained by a network interface regardless of whether communication between the backplane and the at least one I/O module is enabled.

An electronic device includes a housing having a battery chamber and a battery ejector assembled near the battery chamber. The housing has a front surface, the battery chamber is defined in the front surface for receiving a battery therein. The battery ejector includes an ejecting piece comprising an elastic portion, a hinged portion and a pressing portion. The elastic portion is configured for providing an ejecting force to the battery. The hinged portion is disposed at one end of the elastic portion and hinged to the housing. The pressing portion extends and bends from the hinged portion side of the elastic portion opposite to the elastic portion for operating the battery ejector.

The present invention discloses a method for sending/acquiring a SIR target value and a Serving Radio Network Control. The above sending method comprises: a Serving Radio Network Control (SRNC) sending an outer loop power control frame to a Node B, wherein the outer loop power control frame carries carrier identification information and a SIR Target value of a carrier corresponding to the carrier identification information. The above acquiring method comprises: a Node B receiving an outer loop power control frame sent by a Serving Radio Network Control (SRNC) and acquiring carrier identification information and a SIR Target value of a carrier corresponding to the carrier identification information from the outer loop power control frame; and the Node B updating a SIR Target value of the carrier corresponding to the carrier identification information to be the SIR Target value. By means of the present invention, uplink N carrier HSUPA functions can be ensured to be performed correctly and reasonably, and the Node B is enabled to perform power control to independent uplink transmission in an N carrier system.

A method and apparatus is disclosed for calculating a Doppler signal spectrum. The method includes a step of estimating parameters of a Doppler signal, and a step of resolving a predefined spectrum function using the parameters, the spectrum function being at least a function of the parameters characterizing the strength, frequency center, and frequency deviation of the Doppler signal. The apparatus includes an estimating module, a smoothing module, and a calculating module. According to the Doppler signal spectrum calculating method and apparatus of the present disclosure, the obtained spectrogram has very high time and frequency resolution without requiring any complicated operation. Thus, a higher quality spectrogram can be obtained at a very low cost.
