| 20090251411 | Computer input device for automatically scrolling in different speed - A computer input device includes a body and a trace-detecting module coupled to the body. The body has a micro control unit (MCU), and the trace-detecting module has a light pervious area, and a trace-detecting unit. The trace-detecting unit further includes a light source and a sensor. The sensor senses a reflected light beam for a user's digit movement on the light pervious area at a velocity which can be sensed by the sensor. If an automatically scrolling mode is activated and the velocity exceeds a threshold stored in the MCU, then the MCU executes automatic scrolling at a predetermined scrolling speed. | 10-08-2009 |

| 20100059733 | LED Structure - An LED structure includes a first substrate; an adhering layer formed on the first substrate; first ohmic contact layers formed on the adhering layer; epi-layers formed on the first ohmic contact layers; a first isolation layer covering the first ohmic contact layers and the epi-layers at exposed surfaces thereof; and first electrically conducting plates and second electrically conducting plates, both formed in the first isolation layer and electrically connected to the first ohmic contact layers and the epi-layers, respectively. The first trenches or the second trenches allow the LED structure to facilitate complex serial/parallel connection so as to achieve easy and various applications of the LED structure in the form of single structures under a high-voltage environment. | 03-11-2010 |
| 20100060131 | LED BULB STRUCTURE HAVING INSERTION END, AND/OR HEAT DISSIPATION ELEMENT, AND/OR HEAT-AND-ELECTRICITY SEPARATED ELEMENT - An LED bulb structure having an insertion end includes a first electrically conducting pin, a second electrically conducting pin having a die pad at an end thereof, and an LED unit electrically connected to the first electrically conducting pin and the second electrically conducting pin through a first leading wire and a second leading wire, respectively, and a cap enclosing the above-mentioned components and leaving part of the first electrically conducting pin and the second electrically conducting pin exposed thereoutside. The first and second electrically conducting pins are adapted to form bayonet connections. An LED bulb structure having a heat dissipation element has the heat dissipation element attached to the pin portions of the electrically conducting pins. An LED bulb structure having a heat-and-electricity separated element further has a thermally conducting pin. | 03-11-2010 |
