A ride surface for water ride attractions and the like is provided. The ride surface is fabricated from a reinforced membrane material tensioned over a supporting framework. The tensioned membrane ride surface serves the dual role of providing structural support for water flow and riders thereon while at the same time providing an impact safe surface that is non-injurious to riders who may fall thereon. The tensioned membrane can be adjusted actively and/or passively in order to accommodate different and varied ride experiences. Optionally, the shape of the membrane ride surface can be changed either dynamically or passively by special tensioning techniques and/or by using auxiliary support structures such as air bladders, pressure/suction, foam supports or/or the like.

The present invention provides implant devices configured to become anchored within tissue so that they do not migrate despite experiencing aggressive migration forces applied by the highly dynamic movement of muscle tissue that surrounds them. Additionally, methods for placing the devices so that they remain securely anchored within the tissue are provided. The devices are comprised of a flexible body, preferably formed from a helical wound spring. In a preferred embodiment the spring is wound from a ribbon-like filament having series of barbs or ridges formed along the proximal facing edge of the wound ribbon. The ribbon-like filament may be etched from a flat sheet of material, having barbs formed along one edge. The filament may then be wrapped into a helical coil shape to take the form of an implant having barbs formed along the proximally facing edge of each coil to resist migration.

One or more individually addressable pin driver circuits may be communicably coupled to the electromagnet. The individually addressable pin driver circuit is selectively switchable into a number of operating modes that includes a current sourcing mode, a current sinking mode, and an impulse mode. A controller is communicably coupled to each of the pin driver circuits via a digital bus. The controller selects an operating mode and one or more parameters for each of the individually addressable pin driver circuits.

The computer system is comprised of three main components: the core processing trait, the software rules/protocols, and the system architecture. The complete system consists of a number of distributed core processing units distributed in a hierarchical architecture. Core processing units at the top of the hierarchy and at all intermediate levels perform supervisory control, monitoring, and message passing functions. Core processors at terminating points in the hierarchical structure: control and/or monitor devices, machines, and instruments; or execute applications and perform computational functions. Because of the inherent flexibility of the computer system, it can be structured to accomplish any computational task including industrial control and monitoring, data acquisition, instrument control, embedded control, process control and monitoring, general purpose computing and virtually any other computing task.

A kinetic anchoring deployment system utilizing a high-impulse, high-velocity anchor launching mechanism is described herein.
