The present invention provides a low cost device that has a true die to external fiber optic connection. Specifically, the present invention relates to an optical device package joined to a semiconductor device package. In some cases, the combination is joined using wirebond studs and an adhesive material. In other cases, the combination is joined using an anisotropic conductive film. Yet, in other cases, the combination is joined using solder material. Each of these joining mechanisms provides high levels of thermal, electrical and optical performance. The joining mechanisms can apply to optical sub-assembly and chip sub-assembly interfaces in transceivers, transmitters, as well as receivers for opto-electronic packages.
摘要:
Concepts for conveniently arranging devices for the transduction of signals to and from voltage and current domains to infrared radiation domains is described. Specifically, optoelectronic components and methods of making the same are described. In one aspect, the optoelectronic component includes a base substrate having a pair of angled (or substantially perpendicular) faces with electrical traces extending therebetween. A semiconductor chip assembly is mounted on the first face of the base substrate and a photonic device is mounted on the second face. Both the semiconductor chip assembly and the photonic device are electrically connected to traces on the base substrate. The semiconductor chip assembly is generally arranged to be electrically connected to external devices. The photonic devices are generally arranged to optically communicate with one or more optical fibers. The described structure may be used with a wide variety of photonic devices. In some embodiments the base substrate is formed from a ceramic material having the electrical traces formed thereon. In other implementations the substrate includes a backing block having a flexible printed circuit substrate adhered thereto.

The present invention provides a technique for manufacturing a low cost device that provides a true die to external fiber optic connection. Specifically, the present invention relates to several techniques for joining an optical device package to a semiconductor device package. The first technique involves using wirebond studs and an adhesive material, the second technique involves the use of an anisotropic conductive film, and the third technique involves the use of solder material. Each of these techniques provides high levels of thermal, electrical and optical performance. The methods apply to optical sub-assembly and chip sub-assembly interfaces in transceivers, transmitters, as well as receivers for opto-electronic packages.

The present invention relates to the field of biotechnology engineering. It provides a recombinant Escherichia coli that can produce fructosylated chondroitin with high yields and the method for constructing the recombinant strain. The present invention discloses a method for constructing an expression plasmid pETM6R1-RBS-glmM-GGGS-glmS that contains a glmM and a glmS gene under regulation of ribosome binding sites. The recombinant plasmid was transformed into E. coli K4 to obtain a recombinant E. coli strain ZQ33 that can produce fructosylated chondroitin up to 3.99 g·L−1 by fed-batch fermentation in a 5-L fermentor, which was increased by 108.90% compared to that of the wild type strain.
摘要:
A coating system for a surface (such as a floor) including a liquid adhesive layer composition including a heat-activated adhesive that forms an adhesive layer upon drying after application to a surface, and a liquid maintenance layer composition comprising a dispersible polymer that forms a maintenance layer upon drying after application to the adhesive layer. The adhesive layer and the maintenance layer may form a peelable coating. An adhesive strength between the adhesive layer and the maintenance layer may be greater than an adhesive strength between the adhesive layer and the surface. The peelable coating may have a tensile strength that is greater than the adhesive strength between the adhesive layer and the surface. The peelable coating may be configured to be peeled from the surface without the adhesive layer and the maintenance layer separating from one another.
摘要:
Methods, systems, and computer programs are presented for providing a Graphical User Interface in a social network. One method includes an operation for generating post groups for a plurality of user posts. The user posts are to be presented to a user of the social network, and each post group includes user posts created by social contacts in the social network. Additionally, the post groups are sorted according to the post time of the most recent user post within the post group. The method further includes an operation for defining, for each post group, the number of user posts to be displayed for each post group. The post groups are displayed in the order determined by the sorting, where the defined number of user posts is displayed for each post group.
摘要:
A computerized method of creating a classifier model to determine whether a network user should be added to a list of similar network users. A first list of network users, a second list of network users who are not on the first list of network users and characteristic data associated with the network users' network activity are received. A time period is designated. A first category of network activities performed by a network user on the first list within the designated time period is identified. A second category of network activities performed at any time by network users on the second list is identified. A third category of network activities performed by network users on the first list at a time outside of the designated time period is identified. The classifier model is generated based on the first, second and third categories of network activities.
