摘要： A sound attenuation mechanism made up of multiple substrate layers, including corrugated layers. The use of corrugation provides an inexpensive and manner of forming a plurality of highly effective acoustic attenuation channels throughout the mechanism. The multi-layered mechanism may be provided in a variety of modular forms and sizes which may be combined to form a low-cost, highly effective attenuation housing. For example, such a housing may be utilized to contain otherwise noisy large scale oilfield equipment such as coiled tubing engines. Additionally, where drainage from the housing is sought, a spiraled attenuation channel may be employed such that the effectiveness of the attenuation provided by the housing is not sacrificed.

摘要： A method and apparatus for channel assignment within an ad-hoc communication system utilizing multiple channels is provided herein. Individual nodes receive and send route-request (RREQ) packets on all channels rather than a single channel. Each route-request packet comprises a first and a second table. The first table comprises a channel state for the link and the second table comprises a channel quality metric for the link. Each node updates the channel state and channel quality tables and forwards them in the RREQ packet as part of the route-discovery process. When channel selection is made, the channel selection is based on the channel state and the channel quality tables.

摘要： The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.

摘要： Adaptively changing weights for fair scheduling in broadcast environments. In one embodiment, a computer-implemented method allocates bandwidth among a plurality of flows, such as nodes, sharing an output link, such as a network. The method includes adaptively determining a weight for each flow, based on a predetermined criterion, and allocating a portion of bandwidth to each flow proportionally to the weight for the flow. In one embodiment, the predetermined criterion takes into account an input rate of data packets for each flow, while in another embodiment, the predetermined criterion takes into account a queue size for each flow.
