20150036395 | INTERNAL INVERTER COMMUNICATIONS - Inverter internal communication features are disclosed. A multiple-stage inverter includes DC to DC and DC to AC converter switches in different power domains, which share no common return path connection. Operating parameters for converter switches in both power domains are determined by a single controller, located in one of the power domains. Converter control signals are communicated from the controller across an interface between the power domains. Respective, separate controllers in each power domain are not required. Components on each side of the interface could be integrated into respective integrated circuits. A planar transformer implemented in wiring levels of a Printed Circuit Board (PCB) that carries components of the inverter could be provided to enable communications between the power domains while reducing component count and physical space requirements. | 02-05-2015 |

20150381111 | ARC FAULT DETECTION AND EXTINGUISHING - A first switch for connection in a first circuit path between a PV panel string and an inverter in a power system, and a second switch for connection in a second circuit path across an output of the PV panel string, are normally closed and open, respectively, during non-fault operation of the power system. Both series and parallel arc faults in the power system can be extinguished by further control of the switches. Arc fault detection could be based on probabilistic frequency analysis of current or power flow measurements in the PV panel string, current or power imbalance, interruption in communications with the PV panels, or combinations of these techniques. | 12-31-2015 |

20120192283 | Interlocked Binary Protection Using Whitebox Cryptography - A system and method for transforming a software application comprising binary code and optionally associated data, from an original form to a more secure form. The method includes performing a combination of binary transmutations to the application, and interlocking the transmutations by generating and placing interdependencies between the transmutations, wherein a transmutation is an irreversible change to the application. Different types of the transmutations are applied at varied granularities of the application. The transmutations are applied to the application code and the implanted code as well. The result is a transformed software application which is semantically equivalent to the original software application but is resistant to static and/or dynamic attacks. | 07-26-2012 |

20110008576 | Method, Material and Apparatus for Enhancing Dynamic Stiffness - A composite, carbon based material that can be used for enhancing the dynamic stiffness of objects, in the case where it for instance is applied as a coating, comprises at least one layer of substantially parallel carbon pillars. The pillars extend from the bottom surface up to the top surface of the layer, substantially perpendicularly to said surfaces, have substantially hexagonal or pentagonal cross-sections and a relatively weak conical shape, their cross-section widening from their bottom ends to their top ends. The carbon based pillars can typically have a cross-sectional dimension in the range of 50-200 μm such as about 100 μm and have heights in the range of 50 μm-2 mm. The pillars can be seen as built from macro-sized aggregates that have at least one dimension in the nano range, e.g. in the range of 10-800 run, and include carbon, oxygen and hydrogen and in most cases also nitrogen. The material can be produced using PECVD, PEPVD methods and plasma generation by electric discharges with closed electron drift. | 01-13-2011 |
20110081477 | Plasma Activated Chemical Vapour Deposition Method and Apparatus Therefor - In plasma activated chemical vapour deposition a plasma decomposition unit is used that is arranged in or connected to a vacuum vessel having a relatively low pressure or vacuum, to which an operating gas is provided. Periodically repeated voltage pulses are applied between the anode and the cathode of the plasma decomposition unit in such a manner that pulsed electric discharges are produced between the cathode and the surrounding anode of the plasma decomposition unit. The anode is arranged in a special way so that at least a portion thereof will obtain only an electrically conductive coating or substantially no coating when operating the unit. For that purpose, the anode includes a portion located in the direct vicinity of the free surface of the cathode. The portion is a flange or edge portion which is located or extends over margins of the free surface of the cathode. In that way, the anode will include a portion that is shielded for direct coating with particles from the plasma formed and that hence will obtain e.g. substantially no dielectric coating at all. | 04-07-2011 |
