  • Patent number: 8624928
    Abstract: A system and method for magnifying a webpage displayed on a touch screen of an electronic device includes defining a magnification instruction for magnifying content of the webpage on the touch screen, a trigger instruction for each of an automatic mode and a manual mode. The method detects an input instruction according to user input if the electronic device browses webpage. A selected magnification mode is confirmed according to the trigger instruction detected by the electronic device if the electronic device has detected the magnification instruction. The method further confirms a target area to be magnified in the webpage on the touch screen according to the selected magnification mode, and magnifies content of the target area by displaying content of the target area on a full screen of the touch screen.

  • Patent number: 7312996
    Abstract: A heat sink for memory strips comprises two heat transfer plates respectively attached on two sides of a memory strip. The upper edges of the heat transfer plates are further provided with retaining tongues and retaining rings. The extended portion of the combined heat transfer plated above the memory strip forms a heat radiating section which further includes a multitude of radiating fins for enhancing the cooling effect.

  • Patent number: 7286364
    Abstract: A heat dissipating device for a memory chip comprises a heat dissipating body; a middle section of each of two opposite sides of the heat dissipating body having a hook; a distal end of each hook being bent as a hooking end; wherein the hook can be hooked to the penetrating holes of a circuit board by the hooking ends to buckle the penetrating holes so as to fix a memory chip to the circuit board. Each of the four corners of the heat dissipating body is extended with a protrusion which is bent from the heat dissipating body to have the same orientation as the hook. The heat dissipating body has a recess at a center portion thereof. An outer side of the bending section is chamfered as a guiding angle. The hooking end may be a flat sheet, a cambered sheet or a U shape sheets.

  • Patent number: 7190595
    Abstract: A protecting device of a memory module comprises two protecting sheets capable of covering a memory. Each upper edge of the protecting sheet has a buckling sheet and a buckling seat. One buckling sheet of one protecting sheet is capable of being buckled to the buckling seat of another protecting sheet. A front edge of each buckling seat is lowered so as to form an upper section surface and a lower section surface. The buckling hole has a lower buckling hole in the lower section surface and an upper buckling hole at the upper section surface. A front edge of the buckling sheet is lowered so as to form an upper section surface and a lower section surface. The lower section surface of the buckling sheet is formed with a buckling piece; and the buckling piece is extended with at least one tenon.
