Abstract: A system removes a pre-specified amount of material from a body of water to facilitate continued operation thereof. A particular embodiment envisions a sled-like device that, assisted with floats, suitable connectors and a hand winch may be positioned anywhere in the body of water. In operation, it is pulled along the bottom of the body of water at a pre-specified rate via a cable and winch affixed to a ground-anchored cable located on shore. The device is symmetric so that it may be pulled in either direction. At each end of the device is a scoop arranged to dislodge material on the bottom and transfer it to a central pump chamber from which an onboard submersible pump transfers it via a hose to a remote repository for further disposition. The system is compact and simple, both in design and operation, facilitating use and maintenance by existing operations personnel.

Abstract: A network for transferring information among a plurality of digital devices includes a plurality of switching nodes interconnected by communication links. Each of the digital devices is connected to one of the switching nodes over additional ones of communication links. Each communication link transfers information in a predetermined one of a plurality of types of communications services, with the network including at least one communication link of each service type. The digital devices and switching nodes transfer information through the network over virtual circuits, with each virtual circuit extending from one digital device, as an originating digital device, to another digital device, as a terminating digital device. Each virtual circuit defines a unitary virtual circuit path extending through at least one switching node over a plurality of the communication links without regard to the service type of the ones of the communication links included in the virtual circuit path.
