Abstract: A strap connector includes an insulating body, a conductive element, a locking member, a pressing block, and a strap connected with the pressing block. The locking member includes a main body portion and a locking elastic arm. The main body portion includes a top plate. The locking elastic arm extends from the top plate and is used for locking with a mating connector. The pressing block is slidable backwardly under the pulling of the strap, so that the pressing block presses the top plate downwardly, and then the locking elastic arm moves downwardly to realize unlocking. When the unlocking method disclosed in the present disclosure is performed, it is only necessary to ensure that the pressing block slides over the top plate, which improves the reliability of unlocking.

Abstract: Method and system for dynamically screening advertisement on a media are adapted to be used in the field of e-commerce. Information of at least one advertised object and/or at least one advertisement rule of the media are monitored with a monitoring unit to determine if any change occurs. If the occurrence of a change is determined, for example by the monitoring unit, information of the advertised object(s) is examined by a screening unit.

Abstract: An optical assembly, such as a multiple output diode laser pump source for EDFAs, is formed by pressing an optical array emitter chip against a standoff structure protruding from a submount such that the emitter chip deforms to match the curvature of the standoff structure. An IO chip is also juxtaposed against the standoff structure such that its optical receivers can receive optical energy from the emitter chip. The IO chip can provide various optical functions, and then provide an optical array output for coupling into an optical fiber array. The standoff structure preferably contacts the emitter chip over an aggregate contact area much smaller than the area by which the emitter chip overlaps the submount. The materials used for bonding the emitter chip and the IO chip to the submount are disposed in the recesses between standoffs and not on the contact surfaces of the standoff structure.

Abstract: Roughly described, a submount has a standoff structure protruding from its surface. An optical component is pressed against the standoff structure until tilt and planar non-uniformities are removed, and then bonded to the submount using an adhesive placed in the wells between the protrusions of the standoff structure. The standoff structure preferably has a total surface area contacting the optical component which is much smaller than the area by which the optical components overlap the submount. The optical component mounted in this manner can be an optical array component (including an optical fiber array), or a component having only a single optical port. A second optical component can be attached to the submount in the same manner, greatly simplifying the vertical alignment problems between the two components.
