  • Patent number: 7870399
    Abstract: A software system that transforms an original application into an STPM enabled application and runs the enabled application. At protect time, an anti-tamper tool accepts the original application, uses anti-tamper techniques to create a guarded application, creates a security wrapper according to a policy file, and wraps the guarded application to create the STPM enabled application. A trusted service provider is inserted at the entry point of the enabled application. A set of core services is made accessible to the enabled application through the trusted service provider. At runtime the trusted service provider creates a TSP thread and passes a security file to an STPM device driver implementing TPM functionality and protected by anti-tamper techniques. The TSP thread actively monitors the enabled application and interacts with the STPM device driver through the set of core services.

  • Patent number: 7445258
    Abstract: A power striker assembly effects final positioning of a vehicle closure member and includes a fixed frame and a striker member carried on a striker plate for selective engagement of a latch carried on the closure member, to displace the closure member from a presented position to a cinched position. Guide means interconnects the frame and striker plate to effect simultaneous translational and rotational displacement of the striker plate between end limits of travel to produce linear displacement of the striker member. An actuator selectively displaces the striker plate between its end limits of travel in response to a control signal. Finally, an interlock fixes the striker plate in the cinched position in the absence of the control signal.
