| 20120159577 | ANONYMOUS PRINCIPALS FOR POLICY LANGUAGES - Techniques to allow a security policy language to accommodate anonymous credentials are described. A policy statement in a security policy language can reference an anonymous credential. When the policy statement is evaluated to decide whether to grant access to a resource mediated by the policy statement, the anonymous credential is used. The policy language can be implemented to allow one anonymous credential to delegate access-granting rights to another anonymous credential. Furthermore, an anonymous credential can be re-randomized to avoid linkage between uses of the anonymous credential, which can compromise anonymity. | 06-21-2012 |

| 20120173885 | KEY MANAGEMENT USING TRUSTED PLATFORM MODULES - Described herein are techniques for distributed key management (DKM) in cooperation with Trusted Platform Modules (TPMs). The use of TPMs strengthens the storage and processing security surrounding management of distributed keys. DKM-managed secret keys are not persistently stored in clear form. In effect, the TPMs of participating DKM nodes provide security for DKM keys, and a DKM key, once decrypted with a TPM, is available to be used from memory for ordinary cryptographic operations to encrypt and decrypt user data. TPM public keys can be used to determine the set of trusted nodes to which TPM-encrypted secret keys can be distributed. | 07-05-2012 |

| 20120158614 | Executing a Leveraged Long/Short Strategy for an ETF - An ETF uses a leveraged long/short strategy that involves buying fully funded equities that are expected to overperform in the market, selling short equities that are expected to underperform, and buying additional equities that are expected to overperform using proceeds generated from the short sales. This is achieved for an ETF by creating and redeeming ETF shares, wherein the ETF fund manager specifies in a portfolio composition file which equities to buy and which equities to sell short. To create shares of the ETF, an authorized participant transfers these specified positions to the fund manager “in kind” in exchange for ETF shares. To redeem shares of the ETF, the authorized participant transfers the shares back to the fund manager and in return receives these specified positions in-kind from the fund manager. This avoids the need for the ETF fund manager to initiate the short sale. | 06-21-2012 |

| 20130055482 | METHOD FOR DESIGNING A PROTECTIVE GLOVE TO BE USED IN PERFORMING A CYCLE OF MANUAL OPERATIONS IN AN INDUSTRIAL PRODUCTION LINE, AND GLOVE DESIGNED BY THIS METHOD - There is described a method for designing and manufacturing a protective glove, to be used for imparting slight knocks in performing a cycle of manual operations in an industrial production line and for absorbing the counter-knock received when using a tool or equipment gripped by the operator during said operating cycle. There are provided means for sensing the forces the various areas of the hand are subjected to during said operating cycle, and signals of said sensor means are processed so as to obtain a classification of the areas of the hand according to the value of the forces to which they are subjected. The glove is designed having areas that provide differentiated protections, having pads of different thickness calculated as a function of the aforementioned classification of the various areas of the hand. | 03-07-2013 |
