  • Patent number: 8932513
    Abstract: A method of synthesizing mechanically resilient titanium carbide (TiC) nanofibrous felts comprising continuous nanofibers or nano-ribbons with TiC crystallites embedded in carbon matrix, comprising: (a) electrospinning a spin dope for making precursor nanofibers with diameters less than 0.5 J.Lm; (b) overlaying the nanofibers to produce a nanofibrous mat (felt); and then (c) heating the nano-felts first at a low temperature, and then at a high temperature for making electrospun continuous nanofibers or nano-ribbons with TiC crystallites embedded in carbon matrix; and (d) chlorinating the above electrospun nano-felts at an elevated temperature to remove titanium for producing carbide derived carbon (CDC) nano-fibrous felt with high specific surface areas.

  • Publication number: 20110079275
    Abstract: Composite electrode materials for DSSCs, DSSCs incorporating the composite electrode materials and methods for making the composite electrode materials are provided. The composite electrode materials are composed of semiconductor nanofibers embedded in a matrix of semiconductor nanoparticles. DSSCs incorporating the composite electrode materials exhibit both increased carrier transport and improved light harvesting, particularly at wavelengths of 600 nm or greater (e.g., 600 nm to 800 nm or greater).

  • Patent number: 7907119
    Abstract: A theme changeable mouse for automatically matching network communities is provided and can automatically match and link users of individually customized theme website communities by built-in IDs (identifications). The mouse includes a theme cover and a mouse base. The theme cover can be optionally matched and changed, while each of the theme cover has the IDs therein. A recognition processing unit of a control circuit firmware on a printed circuit board in the mouse base is used to execute a recognition process, so that the user can automatically log into a specific website for providing advanced information service if the user is matched.

  • Patent number: 6778166
    Abstract: The present invention is related to a keyless pointer input device, especially to a pointer input device including a control circuit, an optical sensor for detecting the movement of the pointer device and generating respective displacement, a ball shaft type key control element, a bottom plate, and an upper cover casing capable of being moved slightly. Then main parts can be assembled to the upper cover casing. The keyless pointer input device of the present invention is keyless on the appearance of the device. Therefore, the keyless pointer input device can be integral formed with a seat. The ball shaft type key control element is used to cause key signals to be generated by moving the upper cover casing.

  • Patent number: 6679416
    Abstract: A multi-functional welding platform is disclosed. The multi-functional welding platform has a box body at a base thereof. The rear side thereof is installed with a power input end, a power regulator, a high voltage discharging plate, a power output end, etc. A lower side of the platform is installed with an air inlet space. A rear side of the space has a fan. A plurality of air inlet holes are distributed on the platform and filtering material is placed therein. Other than providing the general device for welding, harmful gas or metal smoke enters into the air inlet holes on the platform and then is filtered and then exhausted from the fan so that the operators will not breath harmful gas.

  • Patent number: 6570108
    Abstract: A switch mechanism has a ratchet, two tappets, and two sensors. The ratchet has a plurality of sawteeth. The tappets are installed at two opposite sides of the ratchet. Each sensor is installed beside the ratchet for generating detecting signals. When the ratchet rotates clockwise, the sawteeth of the ratchet will push one tappet toward its corresponding sensor so as to generate corresponding clockwise detecting signals. When the ratchet rotates counterclockwise, the sawteeth of the ratchet will push the other tappet toward its corresponding sensor so as to generate corresponding counterclockwise detecting signals.

  • Publication number: 20020167493
    Abstract: A pointing device has a roller with a plurality of irregular protrusions, a light source for emitting light, a light sensor for detecting light reflected from the roller, and control circuitry for controlling operations of the pointing device. When the roller rotates, reflected light received by the light sensor changes according to the protrusions on the surface of the roller, and the control circuitry generates corresponding pointing signals according to the reflected light received by the light sensor.
