An electrical power generating system is driven by a multi-spool gas turbine engine including at least first and second spools. The first spool comprises a turbine and a compressor mounted on a first shaft; the second spool has at least a turbine mounted on a second shaft that is not mechanically coupled to the first shaft. A main generator is coupled with one of the spools, and an auxiliary generator / motor is also coupled with one of the spools. Speed control of each of the generators is employed for controlling operation of the engine. The auxiliary generator / motor can operate in either a generation mode to extract power from its spool or a motor mode to inject power into its spool.

The present invention provides for the transplantation of tissue from a donor site in a body to a recipient site. The device includes an outer chamber having an interior volume in which a perforated inner chamber can be placed. During the aspiration of tissue, a vacuum is formed in the interior volume of the outer chamber, to draw tissue from a cannula into the perforated inner chamber. The perforations are sized such that fat is collected within the inner chamber, while fluids and other materials are drawn through the perforations, away from the collected fat. For reinjection, the inner chamber can be removed from the outer chamber, and a sleeve positioned to cover the perforations and thereby form a syringe body that can be interconnected to a needle and plunger for reinjection of the collected fat.

An apparatus and corresponding method of use extracts, cools, and transports effluents from subterranean, sub-sea oil formations to distant shore based processing facilities. The effluents, mostly crude oil, are conveyed rapidly to a cold flow generator near the oil wellhead on the sea bottom using the cold seawater to chill the effluents to a dispersed mixture including generated solids. The mixture is transported close to sea bottom temperatures, slowly, with small pressure drops, in low-cost submerged bare pipes over long distances to on or near shore processing facilities that can produce useful hydrocarbon products more cost effectively than at sea processing facilities. The apparatus eliminates or minimizes the need for heated or insulated pipe, the need for large floating processing structures, the need for sub-sea processing equipment, and / or the need for chemical additions to production flow.

An articulating band saw apparatus provides a frame that includes a vertically extending section having upper and lower end portions. An elevator moves between the upper and lower end portions of the frame. A first hydraulic actuator is supported on the elevator for movement therewith. A first arm provides arm end portions, the first arm supported by the first hydraulic actuator. An end of the first arm supporting a second hydraulic actuator that is spaced away from the first hydraulic actuator. The second hydraulic actuator supports a second arm. An endless band type saw is mounted on the free end of the second arm generally opposite the second actuator. The band saw is movable by articulation of the first and second actuators and resulting movement of the first and second arms. In one embodiment, the band saw is a diamond wire saw.

An orthopedic surgery system includes: a retractor support arm; a table mounting assembly for securing the retractor support arm to the operating table; a first blade mounting arm slidably engaging the retractor support arm; a second blade mounting arm slidably engaging the retractor support arm in spaced relationship with respect to the first blade mounting arm; a first retractor blade connected to the first blade mounting arm; a second retractor blade connected to the second blade mounting arm; and a plate support assembly for releasably engaging an orthopedic plate wherein the plate support assembly slidably engages at least one of the retractor support arm or the first blade mounting arm or the second blade mounting arm. In one version of the invention, the system used in anterior cervical spine surgery and the orthopedic plate is an anterior cervical plate.

A wheelchair for animals includes a harness support frame having first and second lateral supports spaced from each other and a width extender adjustably connected between the first and second lateral supports, first and second knuckle clamp assemblies where each one of the first and second knuckle clamp assemblies has a first clamp component and a second clamp component, a plurality of harness connectors attached to the harness support frame, first and second leg assemblies where the second clamp components receives a leg assembly proximal end of one of the first and second leg assemblies, first and second wheels where each one of the first and second wheels is rotatably connected adjacent to a leg assembly distal end of one of the first and second leg assemblies, and a harness assembly detachably connected to the harness support frame. Each first clamp component has a lateral bore for receiving one of the first and second lateral supports therethrough and is positioned between a support frame proximal end and a support frame distal end. Each second clamp component has a clamp recess that receives the leg assembly proximal end and is rotatably and adjustably connected to the corresponding first clamp component.

A floating floor system and a floor panel and method for use with the same that includes an improved mechanical interlock system. The mechanical interlock system allows laterally adjacent floor panels that are mechanically interlocked to slide relative to one another a predetermined distance in a longitudinal direction, while prohibiting relative translation in the vertical and transverse directions. In one embodiment, the predetermined distance eliminates the need for precision cuts during installation, thereby making installation fast and easy. In a further embodiment, the invention optimizes the floor panels (and floating floor system.) to balance ease of installation and horizontal locking strength between laterally adjacent floor panels.

A method and system are provided for analyzing electromagnetic brain signals such as EEG and ECoG signals in a subject in real time and which avoids the need for time-intensive retrospective analysis of brain activity in the subject. This can be applied to all complex systems with multiple fluctuating signals to identify and predict significant events.

A medical needle set for visualized tissue ablation within a subject's body includes a cannula and components configured for inclusion in the cannula, including a trocar for occlusion of the cannula lumen during needle placement, and a visualizing ablation probe used for simultaneous endoscopic viewing and ablation of tissue sites with a laser beam. The cannula can include a tissue-gripping surface for stabilization of the needle set on the target tissue. A surgical system for tissue ablation includes a visualizing ablation needle set operably connected to an endoscope and a laser. A surgical procedure using this system permits simultaneous visualization and ablation of tissues, including those of the facet joints of the spine.

A method of assembly of construction and assembly of golf club head parts used to manufacture golf club heads primarily composed of strong plastic materials that can be formed by injection plastic molding processes in a minimum of two parts. Draft is practical for both molded parts to simplify mold making. A preferred plastic is polycarbonate. Internal reinforcement elements are designed and arranged to provide structural features to facilitate assembly and improve strength of bonds. Internal reinforcement elements may be molded as separate parts to join with the face and shell structure. A hosel, which is not considered part of the shell and which may be made of plastic or metal, is bonded into the golf club head parts described.
