| 20120110784 | PORTABLE DEVICE AND HINGE WITH A FLEXIBLE TUBE - A hinge is mounted in a portable device with two panels and has a flexible tube and a linking unit. The linking unit receives the flexible tube and is attached to the panels of the portable device. Since the flexible tube does not restrict the rotating angle, the panels can stay at any desired visual angle and are pivoted steplessly. | 05-10-2012 |

| 20100244962 | DISTRIBUTED ACTIVE TRANSFORMER BASED MILLIMETER-WAVE POWER AMPLIFIER CIRCUIT - A distributed active transformer (DAT) based millimeter-wave (MMW) power amplifier circuit is designed for power amplification of MMW frequency signals. The proposed MMW power amplifier circuit is characterized by distributing the input frequency signals into two sets of differential signals and by the use of a distributed active transformer circuit unit to process these two sets of differential signals to thereby generate an amplified frequency signal as the end result of output. The invention provides higher and greater added values and power added efficiency (PAE) and is ideal for use in millimeter-wave communications systems with an operation frequency around 60 GHz. | 09-30-2010 |

| 20090108757 | ONE-PIECE ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE WITH AN ENERGY-RECYCLING FEATURE AND HIGH CONTRAST - This invention is an electricity generating organic light-emitting display device (OLED) consisting of vertically stacked layers including an organic light emitting device (OLED), an insulation layer, a solar cell and thin film transistors. The device can reduce the reflection of ambient light, improve the contrast of the signal, and enhance sun-light readability by allowing the ambient light to be absorbed by the solar cells. Furthermore, additional power will be generated by the solar cell through absorption of ambient light and backward emission of OLEDs. The device, without using the polarizer, can exhibit low reflectance characteristics over the visible region and high display contrast. | 04-30-2009 |
