A method for treating a diseased or damaged spinal disc comprises the steps of: (a) providing access to the nucleus pulposus through the annulus; (b) removing at least a portion of the nucleus pulposus to create an intradiscal space; determining the size of the intradiscal space; and (c) sealably introducing under pressure a curable biomaterial through the annulus directly into the intradiscal space. The method may include the additional steps of applying a force to distract the opposing vertebral bodies about the intradiscal space and then removing the distraction force after the biomaterial has cured. The step of determining the size of the intradiscal space may be accomplished by expanding a compliant balloon within the intradiscal space using a contrast medium capable of visualization under fluoroscopy. The curable material is sealably introduced through a vented needle inserted through the opening. The curable biomaterial is introduced until a quantity of the material flows into the vent.

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

Multiple Views of an Industrial Plant are graphically displayed and viewed. A graphical user interface displays the views in corresponding panes or windows of the graphical user interface. The views, being graphical representations of systems of the Industrial Plant, are coupled by a coupler according to a predetermined relationship between the underlying systems of the Industrial Plant represented by the coupled views. The coupler automatically refocuses the panes to display different views of the Industrial Plant based on a selection of an object in any of the panes or on a manual refocus of one view and on the predetermined relationship for coupling the views. The Coupled views represent different domains of the Industrial Plant or Industrial Network e.g. real-time monitoring and operation, configuration, debugging, maintenance, scheduling, asset management, documentation, training, simulation, physical construction, material flow monitoring, programming, interconnecting function blocks, performance analysis. The analysis may be provided at different points in time (now, past, predicted future) and with a different spatial focus (parts, whole). Coupling different views greatly reduces handling effort for building and operating Industrial Plants.

There is provided an apparatus which can simplify, expedite and enhance the segregation of undesirable particles from desirable particles in a multiple-layer flow wherein the desirable and undesirable particles are randomly intermixed with each other. This is accomplished by a stepwise reduction of the thickness of the flow to thus locate all or nearly all undesirable particles at or close to the exposed sides of the resulting relatively thin flow so that the undesirable particles can be readily detected and segregated from the thin flow.

This invention overcomes the disadvantages of the prior art by providing a power generating system particularly suitable for field use in remote locations, which is fuel-efficient, relatively quiet, tolerant of dust, capable of operating on low-grade logistics and diesel-like fuels and capable of generating between 500 W and 2 KW of continuous electrical power. This generating system employs a two-cycle MICE generator having a piston that operates within a cylinder, and an interconnected, axially moving piston shaft that oscillates an alternator coil within a magnetic core. The piston shaft is attached to, and resisted by, the free end of a strong spring with a second, opposing end fixed to the MICE casing. To control operation of the MICE generator a clipper circuit is employed with a set threshold to resolve peaks and an adjustable harshness for applying load to the coil based upon an amps/volt harshness setting. The engine can also be controlled dynamically throughout the cycle using the added feedback from the proportional and integral elements of a PID controller in conjunction with an energy dissipating and/or storing circuit to load the coil. The dynamic control can be based on a switching power supply implementation. Various engine operating parameters can be derived from coil voltage, current and resistance, and used to control and/or monitor the engine's performance.
