| 20100267321 | Air curtain-isolated biosafety cabinet - A biological safety cabinet (BSC) has an air curtain to isolate air inside and outside the BSC. A most preferable slight concave curtain of air can be obtained. With the curtain, neither contamination in the BSC leaks out nor outside contamination enters the BSC. Furthermore, no circulation is formed in the BSC by blowing the air curtain. Thus, the operator using the BSC and the product in the BSC are both well protected. | 10-21-2010 |

| 20090162251 | Air sterilization device with low aerosol bounce - An air sterilization device with low aerosol bounce includes an air conditioning pipe, a porous filter media, and a UV light generator. This porous filter media, it is secured on the fixing portion. This porous filter media has many irregularly distributed channels. The channel is coated with a coating layer having a thickness between 10 μm to 1000 μm sticking aerosols for avoiding bounce effect. The UV light generator can emit UV light to kill biological aerosols. It is suitable for long-term usage. So, the bounce effect of aerosols can be significantly reduced. The maintenance cost is low. The sterilization effect is excellent. Plus, the flow rate of the air conditioning system remains high. | 06-25-2009 |

| 20100053053 | DISPLAY PANEL - A display panel has a display area and a peripheral circuit area next to the display area. The display panel includes a number of pixels, a first signal line, a second signal line, and a third signal line. The pixels are arranged in array in the display area. The first signal line disposed in an intersection of the display area and the peripheral circuit area is electrically connected to the pixels. A data signal is suitable for being applied to the first signal line. The second signal line is disposed in the peripheral circuit area. A common signal is suitable for being applied to the second signal line. The third signal line is disposed between the first signal line and the second signal line. A reference signal is suitable for being applied to the third signal line. The data signal, the common signal, and the reference signal are different signals. | 03-04-2010 |

| 20090284109 | Combined Computer Case - A combined computer case is provided which includes two first panels opposing to each other, at least three support posts respectively located round the first panels and perpendicular to the first panels, and at least three side panels. Each side panel is provided between two neighboring support posts. Each first panel has at least three connecting portions for corresponding to the other first panel. Each support post has first connecting sheets on both ends thereof for corresponding to the first connecting potions of the first panels. The first panels, the support posts and the side panels are pillar or planar components, and respectively act as minimum units of a cubic computer case. In assembly, the first connecting sheets respectively connect with the first panels to form a support frame of a computer case. Finally the side panels are assembled to complete assembly of the computer case. | 11-19-2009 |

| 20090058349 | ANGLE-CALCULATION APPARATUS AND ANGLE-CALCULATION METHOD FOR THREE-PHASE OPTICAL ENCODER - An angle-calculation apparatus for three-phase optical encoder receives three-phase sinusoidal signals 120 degree phase from the optical encoder and obtains angle information for a motor rotor. The angle-calculation apparatus includes an A/D converter, a digital signal processor (DSP), a phase digitalizer and a digital counter. The A/D converter converts three-phase analog signals of the optical encoder into three-phase digital signals. The phase digitalizer converts the three-phase analog signals into digital phase signals. The digital counter generates a counting value based on the digital phase signals. The DSP performs an inverse trigonometric function calculation on a relatively linear region of the three-phase digital signals to obtain the angle information. The DSP obtains the rotation turn number and rotation direction of the motor rotor according to the counting value. | 03-05-2009 |

| 20090125662 | Switch having integrated connectors - A switch having integrated connectors for connecting to computers has a casing, multiple peripheral ports, at least two integrated connectors and a switch unit. The peripheral ports are mounted on the casing and are for connecting respectively to multiple corresponding peripheral devices. Each integrated connector is a peripheral component interconnect express type connector and is for connecting one-to-one to a corresponding computer. The switch unit is mounted in the casing and is connected between the integrated connectors and the peripheral ports to allow a user to select one computer to be connected to the peripheral devices at a time. | 05-14-2009 |
