20090267712 | FEED THRU WITH FLIPPED SIGNAL PLANE USING GUIDED VIAS - An embodiment of the invention includes a high speed feed thru connecting a first circuit outside a housing to a second circuit inside the housing. The first circuit includes a first high speed integrated circuit chip and the second circuit includes a second high speed integrated circuit chip or optoelectronic device. The high speed feed thru includes an inside coplanar structure positioned at least partially inside the housing, the inside coplanar structure connected to the second circuit. The high speed feed thru also includes an outside coplanar structure positioned at least partially outside the housing, the outside coplanar structure connected to the first circuit. A material separates the inside coplanar structure and the outside coplanar structure. At least one guided via extends through the material, connecting the inside coplanar structure and the outside coplanar structure. | 10-29-2009 |
20120032752 | VERTICAL QUASI-CPWG TRANSMISSION LINES - In one example embodiment, a coplanar waveguide signal transition element transitions high-speed signals between vertically stacked coplanar waveguide transmission lines. The signal transition element comprises one or more dielectric layers and a plurality of electrically conductive vias extending through at least a portion of the one or more dielectric layers. The vias include one or more signal vias and one or more ground vias that are configured to transition signals between the vertically stacked coplanar waveguide transmission lines. The signal transition element also comprises a ground plane disposed within the one or more dielectric layers and electrically coupled to the one or more ground vias. The ground plane has one or more openings through which the one or more signal vias respectively pass. | 02-09-2012 |

20160083487 | Functional Polyisobutylene-Containing Oligomers and Polymers - A method of making functional polyisobutylene (PIB)-containing oligomers and polymers. By the disclosed method, the synthesis of functional PIB-containing polymers can be achieved directly under cationic polymerization conditions and does not include any post-polymerization reactions. The desired functionality is introduced by direct Electrophilic Aromatic Substitution (EAS) reaction using substituted phenyl ring carrying desirable functionalities that do not react with Lewis acid but have weak association with Lewis acid, which still allow living polymerization and EAS reaction under living cationic polymerization conditions. In the disclosed method functional polyisobutylene or isobutylene containing oligomers and polymers can be prepared using stoichiometric or near stoichiometric ratios of the capping or functionalization reagent to polymer end-chain. | 03-24-2016 |

20150113251 | Systems and Methods for Register Allocation - System and methods are provided for register allocation. An original code block and a target code block associated with a branch of an execution loop are determined. An original allocation of a plurality of physical registers to one or more original variables associated with the original code block is detected. A target allocation of the plurality of physical registers to one or more target variables associated with the target code block is determined. One or more temporary registers are selected from the plurality of physical registers based at least in part on the original allocation and the target allocation. The original allocation is changed to the target allocation using the selected temporary registers. Specifically, one or more instructions are generated to change the original allocation to the target allocation using the selected temporary registers. The instructions are executed using one or more processors. | 04-23-2015 |
20160062765 | IDENTIFYING SEMANTIC DIFFERENCES BETWEEN SOURCE CODE VERSIONS - The present disclosure relates to a method and system for identifying a semantic difference between source code versions. In one embodiment of the present disclosure, there is provided a method for identifying a semantic difference between source code versions, comprising: obtaining first debugging information of a first source code version and second debugging information of a second source code version respectively; determining, by comparing the first debugging information with the second debugging information, whether in the second source code version there exists a second function matching a first function in the first source code version; and identifying the semantic difference on the basis of a result of the determining. In one embodiment of the present disclosure, there is provided a system for identifying a semantic difference between source code versions. By means of the present disclosure, a semantic difference between various source code versions can be identified rapidly and accurately. | 03-03-2016 |

20160119216 | METHOD AND DEVICE FOR ACTIVATING AND DEACTIVATING SECONDARY COMPONENT CARRIER IN CARRIER AGGREGATION - The present invention relates to communication technology. Disclosed are a method and device for activating and deactivating a secondary component carrier (SCC) in carrier aggregation. When the cache data volume reported by an RLC reaches an activation data volume threshold, increasing the count value of an SCC activation counter instead of directly activating an SCC; when determining that a monitor condition is met, and if the ratio of the count value of the SCC activation counter and the report times of the RLC reaches a set activation threshold, then indicating that the cache data volumes reported for multiple times all reach the activation data volume threshold, and then activating the SCC, thus avoiding multiple activations and deactivations during a short time, and improving SCC rate stability. | 04-28-2016 |
