  • Patent number: 12362939
    Abstract: The present disclosure provides systems and methods for demonstrating the identity of a central processing unit (CPU) to a Trusted Platform Module (TPM) with improved security against, for example, interposers on a communications bus. In particular, according to an aspect of the present disclosure, a CPU can generate a policy alias key that can be used to sign a challenge to prove the identity of the CPU to the TPM. Specifically, the policy alias key can be generated by the CPU by performing a key derivation function on a combined identity value generated by the CPU for the CPU and TPM. The combined identity value can be generated by the CPU from a CPU device identity value and a public endorsement key (EK) associated with the TPM.

  • Publication number: 20240364531
    Abstract: Provided are computing systems that feature a centralized attestation device able to perform attestation on behalf of a number of different platform components. More particularly, the present disclosure provides extensible mechanisms for representing trustworthiness statements by an attester device within a platform either as implicit attestation or explicit attestation. Thus, according to one aspect of the present disclosure, a computing system can include an attester device that implements a hybrid model for presenting evidence of measurements of all the components in a platform to a verifier.

  • Publication number: 20190226918
    Abstract: A contact temperature sensor is disclosed. In an embodiment a contact temperature sensor has a contact body including a bottom wall configured to bring the contact temperature sensor in contact with a test piece, a heat-conducting metal sheet arranged on a side of the bottom wall facing towards the test piece, wherein the heat-conducting metal sheet is configured to conform to a surface shape of the test piece when the contact body is brought in contact with the test piece, a temperature sensor element and a heat-conducting pad arranged to thermally couple the temperature sensor element and the heat-conducting metal sheet, wherein the heat-conducting pad is in each case directly thermally coupled to the heat-conducting metal sheet and the temperature sensor element.

  • Publication number: 20070228600
    Abstract: A method of making containers from resin recycled in a solvent wash followed by carbon dioxide bath that produces essentially contaminant-free synthetic resin material in an environmentally safe and economical manner. The method includes receiving resin particles contaminated with contaminants and then exposing the resin particles to a solvent, which substantially removes the contaminants. The resin particles and the solvent are separated after the contaminants are substantially removed. The resin particles are next exposed to a solvent removing agent, which removes any residual solvent or trace contaminants remaining on the resin particles after separation. After exposure to the solvent removing agent, the resulting resin particles are substantially contaminant and solvent free.

  • Publication number: 20070232784
    Abstract: A two-step resin recycling system and method solvent that produces essentially contaminant-free synthetic resin material. The system and method includes one or more solvent wash vessels to expose resin particles to a solvent, the solvent contacting the resin particles in the one or more solvent wash vessels to substantially remove contaminants on the resin particles. A separator is provided to separate the solvent from the resin particles after removal from the one or more solvent wash vessels. The resin particles are next exposed to carbon dioxide in a closed loop carbon dioxide system. The closed loop system includes a carbon dioxide vessel where the carbon dioxide is exposed to the resin, substantially removing any residual solvent remaining on the resin particles after separation. A separation vessel is also provided to separate the solvent from the solvent laden carbon dioxide. Both the carbon dioxide and the solvent are reused after separation in the separation vessel.

  • Publication number: 20060281896
    Abstract: A resin recycling system that produces essentially contaminant-free synthetic resin material in an environmentally safe and economical manner. The system includes receiving the resin in container form. A grinder grinds the containers into resin particles. The particles are exposed to a solvent in one or more solvent wash vessels, the solvent contacting the resin particles and substantially removing contaminants on the resin particles. A separator is used to separate the resin particles and the solvent. The resin particles are then placed in solvent removing element where they are exposed to a solvent removing agent which removes any residual solvent remaining on the resin particles after separation.

  • Publication number: 20060260693
    Abstract: A check valve for use in a pump. The valve is arranged to be subjected to severe service conditions and high impact loads, yet be resistant to damage to its components. The check includes a body, a valve seat, a poppet and an impact cushion. The poppet is movably coupled to the valve seat and is biased by a spring into engagement with the valve seat. Upon the opening of the valve the poppet moves off of the valve seat and into engagement with the impact cushion against the spring bias. The impact cushion is movably coupled to the valve body and is biased by another spring. When the poppet engages the impact cushion they stay together and move, with the movement of the impact cushion absorbing energy from the poppet.
