A new system and method of available bandwidth estimation applies even where the narrow link and tight link in a network path are in different locations. In embodiments of the invention, a unique packet probe series structure and processing is employed to estimate available bandwidth.

The two small packets, which are impacted little by subsequent narrow links, preserve the spacing set by the tight link, encoding the delay induced by the tight link, all the way to the destination.

This device is a magnetically levitated (maglev) locomotive powered by an onboard nuclear reactor. The locomotive carries a small portable nuclear reactor that heats a fluid to boiling, and passes it through electric turbine engines to produce electric power. The fluid/steam then recirculates through cooling radiators condensing it back to liquid before it passes back into the reactors again. The electric power is used to power and cool the onboard electromagnets, which oppose passive permanent magnets or magnetic coils in the roadbed. The onboard reactor is capable of providing greater electrical power than previously described maglev systems. This, in turn, provides greater power to the superconducting electromagnets, which translates into greater lift capacity and greater speed.

A spinal implant is configured to be received between bony spinal protrusions of adjacent vertebrae particularly, but not necessarily, in the lumbar region of the spine and hold them apart. The spinal implant may be used interlaminar, interbody or interbony protrusion. The present bony spinal protrusion spacer is not fixed to any bony structures of the vertebrae and, as such, use of the present bony spinal protrusion spacer does not result in fusion. It may therefore be removed if necessary. Attachment structures formed as part of the bony spinal protrusion spacer receive and engage portions of adjacent bony protrusions. The attachment structures provide one or more ridges, bumps, protrusions, projections, lips, flanges, overhangs, overhangs that are threadably engaged, extensions and/or the like that form one or more pockets or cavities into which portions of adjacent bony spinal protrusions are separately lodged and held. In this manner (via retention of the bony spinal protrusions), appropriate and/or desired spacing between adjacent vertebrae is maintained. As such, the present bony spinal protrusion spacer is designed to remain safely and permanently in place without attaching to the bone or ligaments of the back.
