Abstract: A computing device and method for providing a user interface for summarizing and presenting information regarding dynamic provisioning and deployment of media processing resources, in a manner that is easy and intuitive and analogizes well to conventional physical media processing deployment. Users are not required to understand hypervisor configuration or virtual machine deployment, or switch through various layers and screens to find configuration information or controls, a process that may be particularly slow, complex, and difficult to learn, particularly for media and broadcast engineers unfamiliar with virtualization technologies. Instead, the present user interface improves efficiency of use of the computing environment for media processing, by providing deployment information in a format similar to physical processing deployment.

Abstract: We receive messages today through multiple channels such as telephone, texts, emails, social media posts etc. and can struggle to prioritize, miss messages, etc. which can impact sales, service, and other customer orientated activities within businesses, service providers etc. Embodiments of the invention exploit a communication model wherein the conventional delay is augmented with filters, recirculating delay lines, decision circuits and loads to exploit an electrical analogy. This model allows different priority messages to be handled and recognizes that messages have different priorities associated with them and that these priorities are dynamic and do not necessarily depend solely upon the sender and recipient but also the context of that communication within an overall activity.

Abstract: Recirculation systems for engine intake air are disclosed having a turbocharger compressor with an inlet and an outlet, a recirculation pathway connecting fluid flow from the outlet of the turbocharger compressor to fluid flow into the inlet of the turbocharger compressor, and a recirculation valve assembly controlling fluid flow through the recirculation pathway. The recirculation valve assembly includes an actuator operating a valve coupled to an aspirator assembly that produces vacuum when the fluid flows through the recirculation pathway from the inlet to the outlet and when fluid flows through the recirculation pathway from the outlet to the inlet. Fluid flows through the recirculation pathway from the outlet to the inlet when the turbocharger generates boost. The vacuum generated by the aspirator assembly is in fluid communication with the actuator to move the valve between two or more positions.

Abstract: Noise attenuation units are disclosed that are connectable in a system as part of a fluid flow path. Such units include a housing defining an internal cavity and having a first port and a second port each connectable to a fluid flow path and in fluid communication with one another through the internal cavity, and a noise attenuating member seated in the internal cavity of the housing within the flow of the fluid communication between the first port and the second port. The noise attenuating member enables the fluid communication between the first port and the second port to flow through the noise attenuating member.
