  • Patent number: 9948074
    Abstract: A circuit breaker arrangement is disclosed. It comprises a cart (1) on which slides a circuit breaker. A lead screw (14) drives the circuit breaker along a linear path by moving a drive block (15), an upper protuberance (211) of which engages the circuit breaker. The arrangement provides for an automatic uncoupling of the circuit breaker at an end position of the drive block (15), where a handle inserted into a hole (24) may turn an end of the lead screw and rock the drive block with a meshing mechanism (43) so that the protuberance (211) escapes the circuit breaker. It is therefore very easy to mount, dismount or replace the circuit breaker. A similar advantage based on unlatching an interlock may be obtained for dismounting the electrical motor (12) that normally drives the lead screw (14). The invention can well take place in the medium voltage industry.

  • Patent number: 9916448
    Abstract: Software development kit (SDK) class tree structures of malicious SDKs are created, with each node of the SDK class tree structures representing a class of a corresponding malicious SDK. An app class tree structure of a mobile app is also created, with each node of the app class tree structure representing a class of the mobile app. To determine if the mobile app has been created (e.g., repackaged or originally created) using at least one of the malicious SDKs, the app class tree structure is compared against the SDK class tree structures to find an SDK class tree structure that matches the app class tree structure. For confirmation, the similarity of classes of the app class tree structure relative to classes of the SDK class tree structure can be determined.
