Abstract: Apparatus and method for realizing tubular optical waveguides in glass by femtosecond laser direct writing. Irradiation in glass with focused femtosecond laser pulses leads to decrease of refractive index in the modified region. Tubular optical waveguides of variable mode areas are fabricated by forming the four sides of the modified regions with slit-shaped femtosecond laser pulses, ensuring single mode waveguide with a mode field dimension compatible with direct coupling to single-mode optical fibers.

Abstract: An electrical connector includes an insulative housing (10), a number of upper terminals (20) and a number of lower terminals (30) received in the insulative housing. The upper terminals comprise a pair of signal terminals (21) and a ground terminal (22) on one side of the pair of the pair of signal terminals; and an insulative body insert molded with the upper terminals to constitute a terminal module. The upper terminal has a fixed portion (201) and an elastic arm (301). Both the fixed portions of the signal terminal and the ground terminal have a same first width (201a). Both the elastic arms of the signal terminal and the ground terminal have a same second width (202a). The second width is wider than the first width. Every two adjacent fixed portions of the upper terminals are equidistant, and every two adjacent elastic arms of the upper terminals are equidistant.

Abstract: A collapsible stand has a first member and a second member. The first member has a containment portion and an engaging portion, a circumference of the containment portion further has a first connecting portion, the second member has an accepting portion and a slot, a circumference of the second member further has a second connecting portion, and the second member engages with the engaging portion of the first member.

Abstract: An image processing method and apparatus, and a shooting terminal, where the method includes acquiring a to-be-processed image that is shot but is not image-processed; extracting shooting characteristic information of the to-be-processed image; performing image processing on the to-be-processed image according to the shooting characteristic information. In this way, after acquiring a to-be-processed image that is shot, a shooting terminal uses shooting characteristic information of the to-be-processed image as a basis of adaptive processing of the image, and performs processing on each to-be-processed image according to shooting characteristic information of each to-be-processed image, so that the quality of an image that is obtained after being processed by the shooting terminal can be adaptively improved.

Abstract: A cable management apparatus includes a guide rail, a number of slide members slidably mounted to the guide rail, and a number of cable supports. Each of the cable supports includes two arms hinged to each other. Each of the arms forms a first end and a second end. The first end of the former one of two neighboring cable supports and the second end of the latter cable support are rotatably connected to the slide member between the neighboring cable supports. The first end of the last cable support is connected to the guide rail. The cable supports are unfolded with the slide members sliding forwards along the guide rail to spread a cable rested on the cable supports. The cable supports are folded with the slide members sliding rearwards along the guide rail to wind up the cable.
