Abstract: The invention is related to a fixture device for motherboard module by placing two fixing plates on the locational surface of a major control device. A ∏-shaped slider with the same width as the motherboard module is formed on the base plate below the fixing plate. Additionally, a locating button in front of the opening of the slider is used to secure the motherboard module into the slider. Through this approach, the motherboard module can be easily installed/disassembled by pressing the locating button without using any tools or test fixtures.

Abstract: The invention relates to a digital television with a device for connecting a digital camera, especially to an inside of a digital television where a base being fixed a computer mainframe thereon, and a leading edge of the computer mainframe being against to a control panel of the digital television for an control panel of the computer mainframe becoming a member of the digital television panel thereof; on the other hand, a top end of a rear casing of the digital television around a screen of the digital television is a cavity, which is specially for a connecting device; the connecting device is a USB socket; an end of a signal line connects to the computer mainframe, another end elongates toward up to connect to the connecting device along with an internal side of the rear casing; the connecting device externally connects to the digital camera; as aforesaid, the combination of the digital television and a video device, it seems that components to construct the video device is less so as to that a personal com

Abstract: The cooling apparatus for illumination system of optical engine of the present invention includes: an illumination system that has a lamp base for its light source, wherein the lamp base has an air duct body fixed on one side of the lamp base, wherein there is at least one partition separating the air duct body into a plurality of air ducts of different surface areas, and an external air duct extending one of the air ducts from underneath the air duct body to outside of the air duct body, wherein a fan installed on the air duct body takes in air through each of the air ducts and the external air duct to cool the illumination system , thus improving the cooling efficiency of the fans, while reducing the volume of cooling air needed from the fans, lowering the cost and reducing the noise from the fans.

Abstract: The present invention relates to an adjustable height apparatus applied to a horizontal projector and comprises a shield assembly, a supporting means, a compression link and a lever. When adjusting the projection elevation, an external force is applied on an adjusting button of the top wall of the projector. The compression link, connecting with the button, makes a vertical movement according to the external force and pushes the detent of the lever to depart from contact with the axial height-positioning component. The sleeve extends toward the outside of said shell by the elasticity of a first elastic component for adjusting a suitable height of the bottom base of the supporting means of the projector.
