  • Patent number: 11328653
    Abstract: A detection device for an insertion slot of an LED display system is provided. When a first receiving card is inserted in the insertion slot, the detection device outputs, to a display panel of the LED display system, a first data output with reference to an image signal outputted by the first receiving card. When a second receiving card is inserted in the insertion slot, the detection device outputs a high-impedance signal to the second receiving card to enable the second receiving card to generate an enabling output, generates a second data output with reference to the enabling output and the image signal outputted by the second receiving card, and transmits the second data output to the display panel.

  • Patent number: 7796875
    Abstract: An exemplary focusing method for enhancing resolution of an optical system is provided. The method includes: focusing on an object and obtaining an image of the object by a lens assembly of the optical system, using a designated point within a motion range of an auto focusing (AF) lens in the lens assembly to calculate; determine a first coordinate and a second coordinate of the AF lens according to resolution of the image; obtaining a direction and distance for positioning the AF lens according to the two coordinates, driving the AF lens to move along the direction of motion, and limiting the range of motion of the AF lens to obtain an optimum focusing location to focus on the object according to the motion distance. A related system is also provided.

  • Publication number: 20080266826
    Abstract: An exemplary assemblable substrate for an SIP includes a substrate and a group of welding pads. The substrate defines a receiving portion therein for receiving a line of pins of the SIP. The group of welding pads is formed on the substrate for electrically coupling the line of pins to the substrate; the group of welding pads being distributed around the receiving portion, two welding pads corresponding to two adjacent pins in the same line being distributed on opposing sides of the receiving portion.

  • Patent number: 5852124
    Abstract: A rubber-modified styrenic resin composition which has high falling impact strength, high gloss, high tensile strength and the product produced from which has little or no unpleasant odor is provided by controlling the residual styrenic monomers in the resin composition to a content of below 1500 ppm and the residual 4-vinyl cyclohexene to a content of below 150 ppm. The number average particle size of the butadienic rubber is 0.08 to 0.35 .mu.m, the amount of butadienic rubber particles having a particle size of below 0.1 .mu.m is 19.5 to 99%, the amount of the butadienic rubber particles having a particle size of between 0.1 to 0.25 .mu.m is 0.5 to 60%, and the amount of the butadienic rubber particles having a particle size greater than 0.25 .mu.m is 0.5 to 80%, based on the total number of the butadienic rubber particles.
