Abstract: A method and apparatus to determine the fractional amount of at least one constituent of a hydrocarbon mixture, comprising dissolving the hydrocarbon mixture in a substantially hydrogen free solvent to produce a diluted solution, the diluted solution having sufficient solvent to render a NMR property of the diluted solution to be predictably related to the constituent concentrations of the hydrocarbon mixture; making NMR measurements on the diluted solution; and determining the fractional amount of at least one constituent of the hydrocarbon mixture from the NMR measurements.

Abstract: A method to obtain a free induction decay signal using includes inducing a static magnetic field in a sample volume. A radio frequency (RF) magnetic field is then induced in the sample volume. The RF magnetic field has parameters selected to minimize the contribution of inhomogeneity to the static magnetic field to a free induction decay time. The free induction decay signal is then detected from the sample volume. In one example, prior to inducing the RF magnetic field, a reorienting radio frequency magnetic field is induced in the sample volume to reorient magnetic spins by a first selected angle. The inducing the RF magnetic field in this example has parameters selected to reorient spins by a second angle. The inducing the RF magnetic field and detecting the free induction decay signal are repeated until nuclear magnetic equilibrium is substantially attained.

Abstract: Content revocation is achieved by disabling licenses issued to a computing device for the content. A content revocation is delivered within a license to the computing device. Upon license storage the content revocation is recognized, validated, and stored in a secure state store under the public key of the content server (PU-CS) that issued the content. Each license has a (PU-CS) therein, and each license evaluation considers each content revocation stored in the state store and having the same (PU-CS). The license is disabled or otherwise affected based on the considered content revocation. A content revocation is one form of a license modification that may be delivered within a license.

Abstract: A method for estimating a concentration of a substance in a test sample of formation fluid, comprising measuring an NMR parameter of a first sample of formation fluid to obtain a first measurement, adding a known quantity of the substance to the first sample to produce a modified sample, measuring the NMR parameter of the modified sample to obtain a second measurement; and determining a relation between the concentration of the substance and a function of the NMR parameter using the first and second measurements and the NMR parameter of the substance.

Abstract: A facility for providing extensible alert types is described. The facility includes an endpoint component that has an associated application, an alert handler component provided by the application for handling received messages and providing alerts to the application, and a message transport component that receives a message, determines whether the message contains an alert, locates an alert handler to handle the alert, and provides a portion of the received message to the alert handler component so that the alert handler component can handle the alert. The facility can receive a request to register an alert handler, add an indication of the alert handler in a mapping data structure and, upon receiving a message containing an alert, identify an alert handler to handle the alert contained in the message.

Abstract: A facility is described for managing parallel requests in a communications environment having devices or applications (“request handlers”) that support serial and parallel message processing. In various embodiments, the facility receives messages directed to a recipient from an application and sends a first message to the recipient without sending subsequently received messages to the recipient. Upon receiving a response from the recipient to the first message, the facility determines whether the recipient supports parallel or serial message processing. When the recipient supports parallel message processing, the facility sends the subsequently received messages to the recipient without awaiting a response to a message before sending another message. When the recipient supports serial message processing, the facility sends a subsequent message after receiving a response to a previously sent message.

Abstract: To render content on a medium, a device obtains a table from the medium, obtains a private key of the device (PR-PD), indexes into an entry of the table based thereon, obtains (PU-PD(RND)) from the indexed-into entry of the table, and applies (PR-PD) to (PU-PD(RND)) to expose a random key (RND). Then, the device obtains (RND(PR-PM)) from the table, applies (RND) to (RND(PR-PM)) to expose a private key of the medium (PR-PM), obtains (PU-PM(KD)) from the license, applies (PR-PM) to (PU-PM(KD)) to expose a content key (KD), obtains (KD(content)) from the storage medium, applies (KD) to (KD(content)) to expose the content.

Abstract: To obtain a digital license for rendering a piece of digital content, a license requester contacts a license provider and sends a license request. The license provider checks the license request for validity and negotiates with the license requestor terms and conditions for the requested license. The license provider generates the requested license and issues the generated license to the license requestor.

Abstract: A retailer facilitates issuance of a digital license from a licensor to a customer for a corresponding piece of digital content. The retailer receives payment for the license from the customer, where the payment is to be shared with the licensor in a pre-determined manner. The retailer also receives customer-based information from the customer. The retailer then composes an actual license request including the obtained customer-based information, and including retailer-based information identifying the retailer to the licensor and acknowledging to the licensor that the retailer owes a portion of the received payment to the licensor. Thereafter, the retailer forwards the actual license request to the licensor. The licensor notes based on the retailer-based information in the actual license request that the retailer identified thereby owes the licensor at least a portion of the forwarded payment.

Abstract: An enforcement architecture and method for implementing digital rights management are disclosed. Digital content is distributed from a content server to a computing device of a user and received, and an attempt is made to render the digital content by way of a rendering application. The rendering application invokes a Digital Rights Management (DRM) system, and such DRM system determines whether a right to render the digital content in the manner sought exists based on any digital license stored in the computing device and corresponding to the digital content. If the right does not exist, a digital license that provides such right and that corresponds to the digital content is requested from a license server, and the license server issues the digital license to the DRM system. The computing device receives the issued digital license and stores the received digital license thereon.

The architecture comprises a base collaboration session, a base activity class, and a well defined contract between the base activity class and the collaboration session. The base collaboration session provides signaling plane functionality, including session management services and media negotiation services. The base activity class provides the base class support needed to build or develop activities derived from the base activity class. The well defined contract enables the base activity class and the base collaboration session to work together to hide the details of the signaling plane from the derived activities.
