Secure master and secure guest endpoint security firewall
Disclosed embodiments relate to a security firewall having a security hierarchy including: secure master (SM); secure guest (SG); and non-secure (NS). There is one secure master and n secure guests. The firewall includes one secure region for secure master and one secure region for secure guests. The SM region only allows access from the secure master and the SG region allows accesses from any secure transaction. Finally, the non-secure region can be implemented two ways. In a first option, non-secure regions may be accessed only upon non-secure transactions. In a second option, non-secure regions may be accessed any processing core. In this second option, the access is downgraded to a non-secure access if the security identity is secure master or secure guest. If the two security levels are not needed the secure master can unlock the SM region to allow any secure guest access to the SM region. |

Secure chip identification using resistive processing unit as a physically unclonable function
A technique relates to biasing, using a control system, a crossbar array of resistive processing units (RPUs) under a midrange condition, the midrange condition causing resistances of the RPUs to result in a random output of low values and high values in about equal proportions. The control system reinforces the low values and the high values of the random output by setting the resistances of the RPUs to a state that forces the low values and the high values having resulted from the midrange condition. Reinforcing the low values and the high values makes the random output permanent even when the crossbar array of the RPUs is not biased under the midrange condition. The control system records a sequence of the low values and the high values of the random output responsive to reinforcing the low values and the high values of the random output. |

Application security policy management agent
A policy generation agent automatically generates a security policy for an application and a security manager. The agent runs the application in a development environment, causing the application to request permissions from the security manager. The agent passes the permissions request to the security manager. The security manger determines whether to approve or deny the request based on a permissions policy. Responsive to a determination to deny the request, the agent generates an updated permissions policy by updating the permissions policy to approve subsequent requests for the permissions. The agent also associates the updated permissions policy with the application, and suppresses any exceptions generated by the security manager in denying the request before approving the request for the permissions in the development environment. |

Archiving accelerator-only database tables
A DBMS manages a high-performance accelerated database that is synchronized with a conventional client database. The accelerated database contains both “regular” accelerated tables, which each duplicate a table of the client database, and accelerator-only tables (AOTs) that are unique to the accelerated database and that may be used for analytical purposes. AOT rows are archived by moving the rows to a dedicated accelerator-only archive stored in the accelerated database. When a user query attempts to access accelerator-only data, the DBMS rewrites the query to adapt the requested operations to the accelerated database's partitioned archive/non-archive structure. The rewritten query specifies steps for accessing archived and non-archived accelerator-only data without forcing the DBMS front-end to generate a merged view of archived and non-archived accelerator-only data. If the accelerator-only archives are stored in a read-only format, the rewriting also adds predictive operations that prevent queries from altering the archives. |

Checking lightning conductors for wind turbines
In a method, impulse response information indicative of an impulse response is determined based on an impulse introduced into a lightning conductor and characterized by an electromagnetic wave. The impulse response information representing at least a waveform and a travel time determined after the introduction of the impulse based on reflection thereof. Evaluation information is specified based on the determined impulse response information. The impulse response information is analyzed at least with respect to the represented waveform and travel time of the introduced and reflected electromagnetic wave. The evaluation information is indicative of whether or not the lightning conductor is functional. The determined evaluation information is output. Also disclosed are a device for practicing this method, a rotor blade for a wind turbine that includes at least one lightning conductor and a device for practicing the method, and a system with one or more devices for practicing the method. |

Self-aligning interface
A self-aligning interface for assembling a powertrain housing 210 of a wind turbine onto a support base 220 is provided. The support base 220 comprises a support surface 230 and the powertrain housing 210 comprises a housing surface 240. The support surface 230 and the housing surface 240 are configured to be in contact after assembly. The self-aligning interface comprises: one or more protrusions 250 on the support surface 230, wherein the one or more protrusions 250 comprises one or more walls 260 which are inclined with respect to the support surface 230; and one or more recesses 270 on the housing surface 240. In addition or alternatively, the self-aligning interface comprises one or more protrusions on the housing surface, wherein the one or more protrusions comprises one or more walls which are inclined with respect to the housing surface, and one or more recesses on the support surface. The one or more protrusions 250 are complementary in size and shape to respective ones of the one or more recesses 270, such that, during assembly of the powertrain housing 210 onto the support base 220, the one or more protrusions 250 act as a guide for the one or more recesses 270, and the one or more protrusions 250 fit directly into the respective one or more recesses 270, to enable direct contact between the support surface 230 and the housing surface 240. |

Method of balancing turbine blades
There is disclosed a method of balancing a set of first and second modular blade sections for a set of blades of a rotor of a wind turbine. The method comprises determining a mass moment of the first and second blade sections, the mass moment being determined about an axis equivalent to an axis of rotation of a hub of the turbine when the blade section is assembled onto the hub. A plurality of blade section groups 10 are defined, each comprising a first blade section of the set and at least one second blade section of the set, each blade section group having a blade section group mass moment about the axis. The first blade section and the at least one second blade section in each group are selected so as to satisfy a minimised total ballast condition, to minimise balancing ballast to be added to the set as a whole, or a minimised 15 ballasting difference condition, to minimise the difference in balancing ballast added to different blades, or both. |

Fuel pump and inlet valve assembly thereof
A fuel pump includes a fuel pump housing with a pumping chamber and an inlet valve bore which extends along an inlet valve bore axis. The inlet valve bore is stepped such that the inlet valve bore includes a shoulder which is traverse to the inlet valve bore axis. A pumping plunger reciprocates within a plunger bore along a plunger bore axis such that an intake stroke of the pumping plunger increases volume of the pumping chamber and a compression stroke of the pumping plunger decreases volume of the pumping chamber. An inlet valve assembly includes a valve seat with a valve seat flow passage extending therethrough, the valve seat abuts the shoulder and is urged toward the shoulder by pressure within the pumping chamber during the compression stroke. The inlet valve assembly also includes a valve member which is moveable between an unseated position and a seated position. |
