  • Patent number: 7304616
    Abstract: An antenna structure includes an antenna portion having an antenna defining a feeding point and a grounding point, and a grounding portion electrically connecting with the grounding point of the antenna. The grounding portion defines a basic board. The basic board is bent upwardly from edges thereof to form a first extending portion. The first extending portion is bent inwardly from a top edge thereof to form a second extending portion approximately paralleling with the basic board. Through the first and second extending portions, the area of the grounding portion is extended. And the electric field is widely distributed all over the whole grounding portion including the basic board and the first and second extending portions to decrease the SAR of the antenna.

  • Publication number: 20070259178
    Abstract: The present invention provides to a method of producing fiber from tourmaline anion fiber; of which, polypropylene or polyethylene chip, TPE and submicrometer tourmaline particle are prepared and then rolled into submicrometer tourmaline agglomerate through granulation by double screw; then, take submicrometer tourmaline agglomerate and polypropylene or polyethylene chip, of which the content of tourmaline agglomerate accounts for 1˜10% of gross weight, and TPE for 1˜40% of gross weight; tourmaline agglomerate and polypropylene or polyethylene are melted into composite fiber or filter material via spinning, such that the fiber or filter material can yield anion and present outstanding gas permeability and mechanical property.

  • Publication number: 20070153092
    Abstract: A video camera apparatus for whole space monitoring is provided, which includes a lens module having a plurality of lenses, a calculation unit, and a processing unit. The lens module captures images from different directions and generates a plurality of image data, then outputs the image data to the calculation unit. The calculation unit calculates the received image data and outputs the image data to the processing unit. The processing unit compresses the image data according to the output of the calculation unit and outputs the compressed image data to the host apparatus.

  • Patent number: 6621915
    Abstract: The present invention disclosed a method and system inspecting cotton web homogeneity by a digital image processing technique, in particular, for an on-line cotton web homogeneity test. It uses optical principles in conjunction with a charge coupled device type camera to find a theoretical equation indicating the correlation between the transmittance of cotton webs and basic weights (weights per unit area). Next, the invention makes use of a numerical analysis method to find the optimal approximation equation representing a relationship between measured transmittance and basic weights of cotton webs. When executing an on-line inspection, a system according to the invention detects the transmittance of cotton webs by means of the computer controlled visual device and then calculates correlated data of cotton web homogeneity variations according to the approximation equation acquired previously.

  • Patent number: 5418996
    Abstract: A shoe washing machine includes a case, a driving means, and a washing means. The case has a cover hingeably connected to the end on the top thereof, a sink being formed at inner portion having an opening at bottom portion adopted to drain water through the opening and out of the case, two water tanks at inner portion having connected with the inner wall in an inclining manner and a plurality of holes all over the tanks' wall. The driving means includes a driving motor adopted to drive a pair of driven motors to rotate. The driven motors drive a pair of discs to rotate, simultaneously. The washing means includes a pump at inner bottom portion of the case, one conduit extending from the pump to the bottom portion of the cover, and two manifolds extending from the conduits into the respective water tanks, each manifold having a plurality of apertures to sparkle water and a brush at the bottom portions to brush the shoes.
