A page flipping method for an electronic device is provided. An exemplary method includes the following steps: displaying an interface comprising a page preview region and a page flipping region; displaying a page on the page flipping region, and displaying an icon group comprising a plurality of icons on the page preview region; determining whether a flipping gesture is applied on the page flipping region; determining the type of the flipping gesture; determining a page flipping manner according to the determined result of the gesture and a function table, and retrieving a corresponding target page according to the determined page flipping manner; creating a new icon group according to the retrieved target page; and displaying the target page on the page flipping region, and displaying the created new icon group on the page preview region. An electronic device using the page processing method is also provided.

A Video-monitor system having basic function: like optic scope, zoom in the target from distance and show read-able picture on display device for shooter. Because digital video could be display on TV, LCD, Laptop and PDA in real-time, it would saving more time on each time to look at target to catch it up then optical scope. The further function: There is a smart marker in screen always move to the last point appeared at target, Let shooter know score immediately after each shooting. At meantime, system gathers and stores all information for recording and later research on shooting-skill training.

A catalyst for the polymerization of propylene comprising components (A), (B) and (C) is provided. Component (A) is a solid product prepared by dissolving a halide of magnesium in a solvent system consisting of an organic epoxy compound, an organic phosphorus compound and an inert diluent to form a homogeneous solution; mixing the homogeneous solution with a halide of titanium to form a mixture; precipitating a solid from the mixture in the presence of an auxiliary precipitant; treating the solid with a polycarboxylic ester to load the ester on the solid; and treating the ester loaded solid with the halide of titanium and the inert diluent. Component (B) is an organic aluminium compound, and component (C) is an organic silicon compound. The particle size of the catalyst can be adjusted by increasing the amount of the inert diluent at a low ratio of the epoxy compound to the phosphorus compound.

A system comprises a network congestion monitoring module for monitoring a congestion-related metric of a wireless medium, the congestion-related metric being based on traffic class, e.g., average contention window; a contention-period/contention-free-period (CP/CFP) adaptation module coupled to the network congestion monitoring module for generating CP/CFP information, e.g., CP/CFP duration information and/or traffic class shifting information, in response to the at least one congestion-related metric; a point coordinator module coupled to the CP/CFP adaptation module for coordinating access to the wireless medium using a point coordination function, e.g., HCCA, based on the CP/CFP information; and a distributed coordinator module coupled to the CP/CFP adaptation module for coordinating access to the wireless medium using a distributed coordination function, e.g., EDCA, based on the CP/CFP information.
摘要:
A method comprises determining whether there is an unused access category higher than a pending access category in a wireless network; and upgrading the pending access category to use at least one MAC layer parameter, e.g., an EDCA parameter, of the higher access category. The method may determine whether an entering access category is higher than the pending access category, and if so then downgrading the pending access category. The downgrading may return the pending access category back to its default access category. The method may determine whether the entering access category is the same as the pending access category, and if so then maintaining the access categories as upgraded. The method may further comprise determining whether the entering access category is lower than the pending access category, and if so then maintaining the access categories as upgraded or upgrading the entering access category to the highest unused access category.
摘要:
A catalyst component for the (co)polymerization of olefins is provided. The catalyst comprises titanium, magnesium halogen and a mixed electron-donor and a catalyst for the (co)polymerization of olefins comprising:(A) the catalyst component; (B) an organic aluminum compound; and (C) an organic silicon compound. A polymer with high and adjustable stereospecificity and broad molecular weight distribution can be prepared by using the catalyst.
摘要:
A catalyst system for the (co)polymerization of propylene contains (A) a solid catalyst component comprising titanium, magnesium, halogen and a 1,3-diether; (B) an organic aluminum compound; and optionally (C) an organic silicon compound. In comparison with the prior art, stereospecificity of the polymer prepared by using the catalyst system of this invention evenl containing no external electron-donor is greater than 99%. Also, the activity of the catalyst system and hydrogen gas adjustability on the molecular weight of the polymer do not significantly decrease.

A method comprises buffering at least one frame for a particular access class, e.g., video, in a transmission queue; performing contention-based procedures for access to a wireless medium; computing the size of the at least one frame in the transmission queue; predicting the size of at least one future frame expected to arrive in the transmission queue during transmission, e.g., using a time-domain or wavelet-domain prediction algorithm, of the at least one frame in the transmission queue on the wireless medium, possibly using a known pattern of frames, e.g., an MPEG GoP; and adjusting a MAC layer time value, e.g., TXOP, based on the size of the at least one frame in the transmission queue and the predicted size of the at least one future frame.
