  • Publication number: 20050276075
    Abstract: A BLU module has a plurality of BLUs assembled together. Each of the BLUs includes a light guide, a light source structure adjacent to the light guide, and a heat conduction member contacting the light source structure. The light guide has a light-emitting surface arranged on a top thereof and a bottom surface opposing the light-emitting surface, the light-emitting surface being larger than the bottom surface so that that light guide defines a first cavity formed therebetween. The light source structure is received in the first cavity. The light guide in two adjacent BLUs of the module defines a second cavity opposite the first cavity for receiving an adjacent heat conduction member of a prior adjacent light guide. The module is provided with a variable size with the BLUs assembled together to meet requirements.

  • Publication number: 20050227819
    Abstract: A shock absorption device of a running apparatus is provided with a shock absorbing elastic member at the rear side thereof. The shock absorption device includes a foot pedal, a lifted base, a support frame and an elastic member. The lifted base is disposed under the foot pedal and the support frame is attached to the bottom of the lifted base. The elastic member is connected to the support frame with a pivotal shaft. When the user runs on the foot pedal, the foot pedal can be lifted an inclining angle with the lifted base rotating with respect to the pivotal shaft to mitigate an impact force caused by the elastic member so as to protect the knees and ankles from injury.

  • Patent number: 6227600
    Abstract: An improved sun visor with a sucker and a Velcro tab is disclosed. The sun visor comprises a reel having a curtain extensively received within the reel. The curtain has a channel along through the bottom thereof and a notch defined in the channel. The sucker and the Velcro tab are located in the notch. The Velcro tab includes an adhesive tape formed on a first face and a hole defined therein. The sucker comprises a suction cup, a protrusion formed on the back of the suction cup, and an aperture defined in the protrusion. The protrusion is inserted into the hole of the Velcro tab via the first tab. A bar is inserted through the channel of the curtain and the aperture of the sucker. The sucker pivots about the bar enabling a user to select the sucker or the Velcro tab to retain the curtain at a desired position.

  • Patent number: 6032718
    Abstract: An adjustable electric sunshade for an automobile has a hollow housing; two covers respectively provided on the both sides of the housing and each having a first ratchet formed therein; a winder provided in the housing and driven by a motor; two elbows pivotally mounted in the housing and each having a second ratchet opposing the first ratchet; two handles respectively pivotally mounted on fingers of the elbows extending out from the covers and each having a protrusion which can ensure the engagement of the first and second ratchets; two flexible arms respectively provided on the elbows; a curtain wound on the winder on one end and attached to the flexible arms on another end. The curtain can be extended by the flexible arms. Turning the handles to release the protrusions can disengage the first ratchet from the second ratchet, so that the elbows can be pivoted to adjust the curtain's angle. By this, the sunshade can be adapted to various rear windows.
