20110016357 | CALL-STACKS REPRESENTATION FOR EASIER ANALYSIS OF THREAD DUMP - Computer systems and methods for call-stacks representation for easier analysis of thread dumps. Execution data for a number of process threads are accessed by a parser in a thread dump wherein execution data includes a number of call-stacks. Process threads have corresponding call-stacks comprising information about active program subroutines of the thread. Threads are grouped in a number of sets that include threads with one or more actions in common. The sets correspond to a same action or subroutine in the call-stacks of the grouped threads. A tree representation of the execution data is generated based on the active actions in the call-stacks. In the tree representation, a first set of grouped threads is a child to a second set of grouped threads when the action corresponding to the first set is invoked by the subroutine corresponding to the second set. | 01-20-2011 |

20120231810 | DECENTRALIZED DATA-TELECOMMUNICATION NETWORK WITH ELEMENT IDENTIFICATION BY THEIR LOCATION, DIAL-UP CHANNEL AND DEVICE FOR SUCH NETWORK - The invention concerns information-telecommunication systems. The mobile network consists of personal broadcasting mobile devices with self-assigned identifiers defining the location of the device at a given time. Commutation in a mobile network occurs by connection of two and more mobile devices located with overlapping of broadcasting coverage areas in a direction from one subscriber to another. The mobile device for operation in such a network supports the function of location definition. When the location of the connected devices is changed and the coverages are separated, and also for equal network workload and load balancing of the sources of power supply, the dial-up channel can be dynamically readjusted | 09-13-2012 |

20150185422 | DEVICE FOR ROUTING LIGHT AMONG A SET OF OPTICAL WAVEGUIDES - Light streams are routed. A transparent plate can be provided in which at least 2 waveguides converge on an active region, wherein the active region comprises a switching element, which can be utilized to extract a portion of the light stream or combine two or more wavelength portions for form a subsequent light stream. Cladding material constrains a light stream to a waveguide. Ion bombardment can be utilized to form micropores in the cladding material, and subsequent etching can enlarge the micropores to form larger diameter pores (of nanometer scale) in the switching element. The pores can be filled with liquid crystal, which can be in a passive state with a first refractive (RI) index, and a second active state (electrical voltage applied) with a second RI. By adjusting the RI. the light stream can be diverted by operations of refraction, diffraction, reflection, etc. | 07-02-2015 |
