The nanofiber layer thereof is constructed by at least two nanofibers, uniformly entangled with each other, with different fiber diameter distributions. Therefore, the nanofiber filter medium of the invention is completed. The described nanofiber filter medium has a low pressure drop and high filtration performance.
Abstract:
A computer implemented method for retrieving video clips from a database is disclosed. The method may include retrieving in an initial query from a video collection based on a search term; receiving a user selection of at least one video clip from a first set of video clips corresponding to the search term; associating at least one visual attribute of the selected video clip with the search term; receiving the at least one search term from a user in a subsequent query; determining a set of physical concepts based on the at least one search term; mapping the set of physical concepts to a plurality of visual attributes; searching the database for at least one video clip corresponding to the plurality of visual attributes; identifying at least one video clip in the database having the plurality of visual attributes; and returning a second set of video clips having the set of visual attributes to the user, the second set including the at least one video clip.

The invention also discloses a method for treating wastewater containing metal ions using the disclosed adsorptive ion-exchange material.
Abstract:
An activated carbon fiber for fabricating a supercapacitor electrode and its precursor material are provided. The precursor material of the activated carbon fiber includes polyacrylonitrile (PAN) and a polymer having formula (I): wherein R1 is cyano, phenyl, acetate, or methoxycarbonyl, R2 is R3 is C1-7 alkyl, X is chlorine, bromine, tetrafluoroborate (BF4), hexafluorophosphate (PF6), or NH(SO2CH3)2, and m/n is 1-99/99-1.
Abstract:
A wiper blade structure comprises a pivot assembly, a plurality of deflectors, a plurality of end ferrule caps, a resilient strip, and a blade element. The pivot assembly may comprise a connecting adapter for engaging various wiper arms and the connecting adapter is further coupled with a pivot socket settled on the resilient strip, so that the connecting adapter can be easily connected with various wiper arms. Besides, by the combining structure among the pivot socket, end ferrule caps and the resilient strip, as well as the combination among the deflectors, resilient strip and the blade element, the wiper blade can firmly and closely contact the windshield glass, so that the defects of the conventional wiper blade structures can be remedied. Thus, the disclosed subject matter can perform improved efficiency of use and therefore is an invention having utilitarian value.
Abstract:
The present invention provides a virtual data collection system and method that provides an image analyst with full-control of the image, including the ability to retrieve and reorganize information from an existing video database of images. The system provides for the search and retrieval of information from previously collected images, and reorganize them to meet new or revised mission objectives. The system also enables quick access of the “right” information through virtual data collection from the existing video database.
Abstract:
A backlight module including a control unit, a backlight driving unit, a first light source set, and a second light source set is provided. The backlight driving unit is controlled by the control unit to generate a driving command to light on/off the light source sets. Therefore, the first and second light source set can be lighted on or off by turns according to a predetermined value, e.g., a time interval, times of power on operations. Otherwise, the second light source set may be used to compensate a brightness loss of the first light sources set when the displaying brightness is not enough, so as to maintain the displaying brightness within a predetermined range. Therefore, a longer lifetime of the backlight module can be obtained.
Abstract:
A passbook conveyance roller device comprises a conveyance roller and a pinch roller, which are arranged to be opposed to each other, to convey a passbook. The conveyance roller comprises an inner ring member connected to a drive shaft, a metallic outer ring member, and a rubber member fixed to, for example, an outer peripheral surface of the inner ring member and press fitted into an inner peripheral surface of the outer ring member to give elastic forces to the inner peripheral surface of the outer ring member in a plurality of positions, which are spaced circumferentially at predetermined intervals from one another and arranged in point symmetry. Both the inner ring member and the outer ring member are rotated through the elastic member when a load torque on the outer ring member is less than a set torque set by the elastic forces of the rubber member. Relative slip is generated between the inner peripheral surface of the outer ring member and the rubber member when a load torque on the outer ring member is equal to or larger than the set torque.
Abstract:
A method for encoding a frame of visual data which includes the steps of encoding an original full resolution frame, storing coded data for the encoded full resolution frame, reconstructing and storing encoded full resolution frame, downsampling the original full resolution frame to render it a reduced spatial resolution frame, encoding the reduced spatial resolution frame, storing coded data for the reduced spatial resolution frame, reconstructing and storing the reduced spatial resolution frame, upsampling and storing the reconstructed reduced spatial resolution frame, comparing a characteristic in the reconstructed full resolution frame with said characteristic in the original full resolution frame to determine the deviation of the reconstructed full resolution frame from the original full resolution frame with respect to said characteristic, comparing said characteristic in the upsampled reconstructed spatial reduced resolution frame with said characteristic in the original full resolution frame to determine the deviation of the upsampled reconstructed spatial reduced resolution frame from the original full resolution frame with respect to said characteristic, selecting the frame with the lesser deviation from the original full resolution frame with respect to said characteristic, and outputting the coded data corresponding to the frame with the lesser deviation from the original full resolution frame with respect to said characteristic to the bitstream.
