  • Patent number: 8292672
    Abstract: A flash memory device includes a Chip-On-Board (COB) type circuit board and a number of first and second contacts electrically connected to the circuit board. Each first contact includes a stiff first contact portion formed on an upper surface of the circuit board. Each second contact includes a cantilevered planar second contact portion extending along the front-to-rear direction. When the flash memory device is inserted into a USB 3.0 receptacle connector, the first and the second contact portions jointly electrically connect with the USB 3.0 receptacle connector. The planar second contact portions provide larger contacting area for mating with the corresponding contacts of the USB 3.0 receptacle connector.

  • Patent number: 7918564
    Abstract: A cooling system for a projector is provided and disposed in the projector. When a sensing temperature of the projector sensed by a thermal sensor of the cooling system is higher than a maximum temperature, a control module controls a fan to increase a rotation speed. When the sensing temperature of the projector sensed by the thermal sensor is lower than a minimum temperature, the control module controls the fan to decrease the rotation speed. As a result, the temperature of the projector is maintained within a proper range.

  • Publication number: 20070206162
    Abstract: An optical projection apparatus comprising an illumination system, a light valve, an imaging system, a power supply circuit and a generator are provided. The illumination system with a color wheel is providing a light beam. The light valve is disposed on the transmitting path of the light beam for transforming the light beam into an image light beam. The imaging system is also disposed on the transmitting path of the image light beam. The power supply circuit is electrically connected to the illumination system and the light valve is connecting with an external power supply. The generator is electrically connected to the power supply circuit. The color wheel connected to the generator drives the generator to generate electric power. The electric power is transmitted to the power supply circuit and powers the optical projection apparatus. Consequently, overall power consumption of the optical projection apparatus is reduced.
