Abstract: An example loading regulator having an internal relief valve apparatus includes a body having a loading diaphragm disposed between a first casing and a second casing. The first casing and a first side of the loading diaphragm define a first chamber and the second casing and a second side of the loading diaphragm define a second chamber. A  relief valve assembly is coupled to the loading diaphragm. The relief valve assembly includes a relief valve seat having an aperture that forms a passageway to fluidly couple the first chamber and the second chamber and a relief valve plug movably coupled to the relief valve seat. The relief valve plug is to move away from the relief valve seat to a bleed position to allow the flow of fluid between the first chamber and the second chamber in response to an outlet pressure substantially greater than a pressure at which the loading regulator enters a lock-up condition.

Abstract: Methods, systems and architectures for processing renderable digital content are described. The various embodiments can protect against unauthorized access or duplication of unprotected content (i.e. decrypted content) once the content has reached a rendering device such as a user's computer. A flexible framework includes an architecture that allows for general media sources to provide virtually any type of multimedia content to any suitably configured rendering device. Content can be protected and rendered locally and/or across networks such as the Internet. The inventive architecture can allow third parties to write components and for the components to be securely and flexibly incorporated into a processing chain. The components can be verified by one or more authenticators that are created and then used to walk the chain of components to verify that the components are trusted. The various embodiments can thus provide a standard platform that can that can be leveraged to protect content across a wide variety of rendering environments, content types, and DRM techniques.

Abstract: An uplink channel response matrix is obtained for each terminal and decomposed to obtain a steering vector used by the terminal to transmit on the uplink. An "effective" uplink channel response vector is formed for each terminal based on its steering vector and its channel response matrix. Multiple sets of terminals are evaluated based on their effective channel response vectors to determine the best set (e.g., with highest overall throughput) for uplink transmission. Each selected terminal performs spatial processing on its data symbol stream with its steering vector and transmits its spatially processed data symbol stream to an access point. The multiple selected terminals simultaneously transmit their data symbol streams via their respective MIMO channels to the access point. The access point performs receiver spatial processing on its received symbol streams in accordance with a receiver spatial processing technique to recover the data symbol streams transmitted by the selected terminals.

Abstract: Systems and methods for determining an average retirement age index, the index including a year and week. The method determines a wealth at death of an average couple for a first retirement age. If wealth at death is greater than zero, the retirement age is decreased by one and the wealth at death value is recalculated. This process continues until the wealth at death value is less than zero, at which point the year of the retirement age index is determined by adding one to the current year of the retirement age. The week of the retirement age index is determined by: dividing the opposite of a wealth at death value for the year prior to the year of the average retirement age index by a wealth delta and multiplying the result by fifty-two.

Abstract: A first device with a changing identity establishes a secure connection with a second device in a network by acting as its own certificate authority. The first device issues itself a self-signed root certificate that binds an identity of the first device to a long-term public key of the first device. The root certificate is digitally signed using a long-term private key, where the long-term public key and the long-term private key form a public/private key pair. The first device provides its root certificate to the second device in any trusted manner. The first device can then create a certificate for one or more short-term identities acquired by the first device and sign the newly-created certificate using the long-term private key. The first device can authenticate itself to the second device by sending the newly-created certificate to the second device.
