| 20110214851 | USE OF A GRAPHITE HEAT-DISSIPATION DEVICE INCLUDING A PLATING METAL LAYER - The present invention relates to a heat-dissipating device for an electronic device, comprising a graphite planar body, one or more metal layers, an insulation film and an adhesive. The heat-dissipating device is optionally attached to a heat sink. The method of using the heat-dissipating device to dissipate heat is also disclosed. | 09-08-2011 |
| 20110080661 | LENS DISPLACEMENT DEVICE, FLEXIBLE PIECE AND THE MANUFACTURING PROCESS THEREOF - A lens displacement device includes a flexible piece, a fixed element and a mobile element. The flexible piece has a support, a flexible part and an oscillation absorber. The flexible part connects to the support and at least one gap exists between the flexible part and the support. The oscillation absorber is installed in the gap between the flexible part and the support. Moreover, the fixed element couples to the support of the flexible piece, and the mobile element couples to the flexible part of the flexible piece. Furthermore, the flexible part of the flexible piece is deformed in shape for providing a restoration force with the mobile element. A manufacturing process of the flexible piece is also disclosed. | 04-07-2011 |
| 20110043935 | LENS ACTIVATING DEVICE - A lens activating device includes at least one elastic piece, at least one stationary piece and a movable piece. At least one elastic piece has at least four sheet portions and four sets of elastic portions. Each set of the elastic portions are serpentine and connected between two sheet portions in order to make the at least one elastic piece form a closed ring. The stationary piece is connected to two sheet portions, and the movable portion is connected to the other two sheet portions. The elastic force generated by the four sets of elastic portions exerts a restoring force on the movable piece. Via this arrangement, the slight rotation of the movable piece within the lens activating device can be reduced. Further, the problem that the elastic piece may scrape the neighboring elements can be prevented. | 02-24-2011 |
| 20100243230 | HEAT-DISSIPATING DEVICE INCLUDING A PLATING METAL LAYER - A heat-dissipating device includes: a planar body made of a graphite laminate and extending along an x-y plane of the graphite laminate; and a plating metal layer formed on the planar body. The heat-dissipating device further includes a metal panel. The planar body is connected substantially perpendicularly to the metal panel. A method of making the heat-dissipating device is also disclosed. | 09-30-2010 |
| 20090030546 | Apparatus and method for positioning control - The present invention discloses a positioning control apparatus which receives a moving command and a feedback signal outputted from a controlled device, and controls the controlled device for moving and positioning. The positioning control apparatus includes a first control loop, a second control loop and an arbitration module with a dead point default value, wherein the first control loop is used to control the controlled device moving in response to the error of the moving command and the feedback signal, on the other hand, the second control loop is used to control the controlled device positioning. Furthermore, the arbitration module compares the default value of dead point with the moving command so as to enable either the first control loop or the second control loop. | 01-29-2009 |
