The disclosure discloses a method for adjusting a mobile terminal browser, which comprises setting an upper threshold value and a lower threshold value of a downloading speed for a mobile terminal browser. The method further comprises: calculating a current average downloading speed of the mobile terminal browser; comparing the current average downloading speed with the upper threshold value and the lower threshold value of the downloading speed; resetting network parameters of the mobile terminal browser when the current average downloading speed is less than the lower threshold value of the downloading speed or greater than the upper threshold value of the downloading speed. The disclosure also discloses a mobile terminal. The disclosure optimizes the network parameters of the mobile terminal browser according to the current network environment, and simultaneously increases downloading efficiency and stability of the mobile terminal browser, thereby avoiding the process of manually setting the relative network parameters of the browser by a mobile terminal user according to different network environments, so that the browser is more humanized and user experience is greatly improved.

An intracavity resonant Fabry-Perot saturable absorber (R-FPSA) induces modelocking in a laser such as a fiber laser. An optical limiter such as a two photon absorber (TPA) can be used in conjunction with the R-FPSA, so that Q-switching is inhibited, resulting in laser output that is cw modelocked. By using both an R-FPSA and a TPA, the Q-switched modelocked behavior of a fiber laser is observed to evolve into cw modelocking.

An automatically-activated laser scanning 2-D bar code symbol reading system employing a visible linear-type laser scanning pattern and an audible feedback signal during scan data capturing and buffering operations. The system includes a laser scanning 2-D bar code symbol reading mechanism that automatically produces a visible linear-type laser scanning pattern for scanning a 2-D bar code symbol structure on an object as its hand-supportable housing is manually transported past a 2-D bar code symbol along a height-wise direction by an operator, automatically capturing lines of scan data from the scanned 2-D bar code symbol structure, decode processing the scan data, and generating a symbol character data string representative of the read 2-D bar code symbol.

The invention is in the field of distributed Raman amplification for digital and analog transmission applications and other applications, e.g., instrumentation and imaging applications, including HFC-CATV applications. In particular, the invention uses a high power broadband source of amplified spontaneous emission (ASE) as the Raman pump source for improved system performance. The invention also includes methods for constructing such a high-power broadband Raman pump.

A method and system for establishing an Internet Protocol (IP) connection between mobile terminals and a mobile terminal for establishing an IP connection are disclosed. The method includes: a request terminal sending a request short message to a called terminal; the called terminal getting the program name by parse, searching out a corresponding end-to-end program in an end-to-end program list and displays it to a user after the request short message is detected and the user chooses to receive the short message; the end-to-end program of the called terminal sending a network connection request after the user starts the end-to-end program and inputs the IP address of the short message text; the end-to-end program of the request terminal performing an IP-based data interaction with the called terminal when the network connection request is monitored. This technical solution can establish an end-to-end IP connection between two mobile terminals rapidly and conveniently.
摘要:
An automatically-activated wireless code symbol reading system comprising a hand-supportable housing having a manually-activatable data transmission switch under automatic communication range dependent control. When a bar code symbol is read, the bar code reader is located inside the predetermined RF data communication range of the system, then the symbol character data string, produced at substantially the same time as the manual activation of the data transmission switch, is transmitted to the base station over the wireless RF communication link. If the device is outside the range, then an audible and/or visual indication is automatically generated, and the packaged symbol character data string is packaged and transmitted to a data storage buffer aboard the bar code reader. Then when the bar code symbol reader is moved within the communication range of the system, the buffered/packaged symbol character data is automatically transmitted to the base station by the RF-based data communication link.
