Abstract: Techniques are provided for allocating resources over a network. A resource consumer requests access to a resource over a network. As part of that request, the resource consumer acquires information that permits it to securely communicate with a resource provider. The resource provider controls the resource and once satisfied with the security of a request from a resource consumer allocates the resource for access by the resource consumer.

Abstract: A noninvasive technique that can be used to deny blood flow to a particular region of tissue, without the inherent risks associated with invasive procedures such as surgery and minimally-invasive procedures such as embolization. Blood flow in selected portions of the vasculature can be occluded by selectively treating specific portions of the vasculature with high intensity focused ultrasound (HIFU). The occlusion denies undesired tissue the nutrients and oxygen provided by blood flow, causing necrosis in the undesired tissue. An imaging technology (such as magnetic resonance imaging, magnetic resonance angiography, ultrasound imaging, Doppler based ultrasound imaging, or computed tomographic angiography) is used to identify the undesired tissue, and the vascular structures associated with the undesired tissue.

Abstract: Techniques are provided for establishing privileged paths for data packets over a network. A data packet is received with a header; the header includes a route selector. The route selector assists in resolving a privileged path for the data packet. The data packet is injected into the network over the resolved privileged path.

Abstract: Techniques are provided for the delivery of client services and for the establishment of client processing environments. A client receives services within a processing environment which is defined by a processing container. The processing container includes one or more processing groups, and each processing group has a particular context that supports one or more applications or services which are processing within that context. The processing groups communicate with one another via connector interfaces included within the processing container. Services and processing containers can be dynamically added or removed from the processing container.

Abstract: A method and apparatus for allowing a transparent service option transition between at least two wireless communication devices (WCDs). A first communication between a first WCD and a second WCD is established using a first service option. At some point during the first communication, a transition to a second service option, such as an asynchronous data service option, is initiated. At least one of the WCDs provides an identification code to the other WCD using a signaling protocol over the first service option. The first communication is then terminated. A second communication using the second service option is then initiated by one of the WCDs, resulting in a seamless transition to the second service option.

Abstract: Topical drug delivery formulations with optical amounts of vasodilator. Vasodilator chemicals applied topically dilate the blood vessels in the skin tissue, which have been shown to facilitate or inhibit systemic or skin tissue deposition of drug substances. The level of stimulation and/or inhibition has been found to be dependent on the concentration and the identity of the specific vasodilator chemical(s) used as well as the drug molecule(s) to be delivered. This work teaches the need to consider specific formulation requirements when dealing with vasodilator chemicals for the creation of successful delivery vehicles in the transdermal drug delivery system. These requirements for very low concentrations of vasodilators were an unexpected and a surprise finding, in contrast to the concentrations of the vasodilators typically used to elicit an increase in skin blood flow.

Abstract: A method for determining and demonstrating the role of vasodilator chemical agents in the development and practice of transdermal drug delivery systems. Vasodilator chemicals applied topically dilate the blood vessels in the skin tissue, which have been shown to facilitate or inhibit systemic or skin tissue deposition of drug substances. The level of stimulation and/or inhibition has been found to be dependent on the concentration and the identity of the specific vasodilator chemical(s) used as well as the drug molecule(s) to be delivered. This work teaches the need to consider specific formulation requirements when dealing with vasodilator chemicals for the creation of successful delivery vehicles in the transdermal drug delivery system. These requirements for very low concentrations of vasodilators were an unexpected and a surprise finding, in contrast to the concentrations of the vasodilators typically used to elicit an increase in skin blood flow.

Abstract: A system for the delivery of chemical vasodilators into the skin for the purpose of increasing the blood flow in a tissue that exhibits compromised circulation. The designated purpose of this increased blood flow is to transiently reverse or inhibit or prevent the onset of an associated medical affliction that may in part or in whole, be either the consequence of that medical condition or participating in the clinical symptoms and etiology of that medical condition. The process and the effect of the topical delivery of a chemical vasodilator has been previously demonstrated for other medical and pharmaceutical applications, however the specific use of this class of drug molecules for the focused effect of improving blood flow to the skin and surrounding tissue with the goal of improving the metabolic health of the tissue and to possibly affect the symptoms of a medical condition is the specific aim of this patent.

Abstract: Techniques are provided for serializing events of a data stream. Meta information defines information unit separators and context for events within the data stream. The data stream is parsed according to the instructions of the meta information and event data associated with the events of the data stream are retained. The event data is packaged into selective groupings of event data and transmitted to one or more services in data formats used by the services. The services perform one or more actions based on the received selective groupings of event data.

Abstract: Techniques are provided for establishing and managing a distributed credential store. An identity service aggregates identity information from one or more identity stores and maintains the information as a remote credential store. Initially, the remote credential store, or portions thereof, is transmitted to a principal service as an initial configuration of a local credential store. A principal interacts with the principal service for defining or modifying a policy that identifies portions of the remote credential store which are to be synchronized with the local credential store. In some embodiments, the principal interacts with the principal service for defining a local policy that identifies portions of the local credential store which are not synchronized with the remote credential store. The interactions between the credential stores are trusted and secured.

Abstract: Techniques are provided for dynamically establishing and managing trust relationships. A first principal initially requests a community list. The community list includes identities of one or more second principals with which the first principal can establish trusted relationships with. The community list is associated with a trust specification. The trust specification defines the policies and access rights associated with interactions between the first principal and the second principals during any active trusted relationships. The first principal can dynamically subdivide, manage, and modify entries of the community list and the trust specification, assuming any such modifications are permissible according to global contracts and policies associated with the first principal.

Abstract: A sealing system for a solenoid, typically for use with high pressures and for small molecule gases, utilizes a piston having a hemispherical sealing face in combination with an insert having a sharp edged seat, the piston and the insert both being aligned in a bore having a common centerline to provide repeated reliable mating and sealing of the piston and the insert. Either the sealing face or the insert is made of a plastically deformable elastomeric material which is initially deformed to seal against the other, which is typically metal.

Abstract: A fluid-flow control system for a valve comprises a valve body and a bi directional main flow passage between a first and second fluid areas. The shuttle piston having a first face in direct communication with the second area and a second face in communication therewith through a bleed orifice. The second face is alternately exposed to the first fluid area through a backpressure passage and second orifice which alters the pressure differential across the shuttle piston. A second valve such as a solenoid operates to either close the second orifice wherein the shuttle piston is operable under differential pressure between the first and second pressure areas, or to close the second orifice wherein the shuttle piston is operable under differential pressure between the second pressure area and the backpressure passage. Filters at the fluid inlet and outlets protect the sealing components therein.

Abstract: Techniques are provided for controlling access to a resource based on access policies and attributes. A principal issues a request to a service for purposes of accessing a resource. The principal is authenticated and a service contract for the principal, the service, and the resource is generated. The service contract defines resource access policies and attributes which can be permissibly performed by the service on behalf of the principal during a session. Moreover, the session between the service and the resource is controlled by the service contract.

Abstract: Methods, systems, and data stores generate and manage temporarily assigned identities. A requestor issues a request for a service. The request includes an identity used for authenticating the requestor. The identity is used for generating an identity configuration and for generating a temporarily assigned identity that is updated to a protected identity directory. The request and the temporarily assigned identity are transmitted to the service. The service uses the temporarily assigned identity to access the protected identity directory for purposes of authenticating the request. The service uses the authenticated request to access attributes associated with the temporarily assigned identity.
