20110083432 | Internal combustion engine and supercharger - A diesel or diesel-like internal combustion engine drivably connected to a variable internal compression ratio supercharger that supplies varying amounts of air to the engine responsive to the load requirements of the engine. The supercharger has a pair of rotors concurrently driven by the engine to move air to the engine. A slide assembly associated with screw rotors is movable with a controller relative to the rotors to bypass air to atmosphere and regulate the amount of air and pressure of the air compressed by the screw rotors to the engine to increase the engine's efficiency. | 04-14-2011 |
20110083647 | Internal combustion engine and supercharger - An internal combustion engine drivably connected to a variable displacement and variable internal compression ratio supercharger that supplies varying amounts of air to the engine air intake manifold that can range selectively from below through above atmospheric pressures responsive to the power requirements of the engine. The supercharger has a pair of rotors concurrently driven by the engine to move air to the engine. A slide assembly associated with screw rotors is movable with a controller relative to the rotors to bypass air to atmosphere and regulate the amount of air and pressure of the air above atmospheric pressure compressed by the screw rotors to the engine to increase the engine's efficiency. When operating at part-load unboosted, a throttle valve is operable to control the air mass flowing to the air intake manifold below atmospheric pressure to control the power of the engine. | 04-14-2011 |

The supercharger has a pair of screw rotors driven by the engine to move air to the engine and a control apparatus for varying the mass and pressure of air supplied to the engine. | 08-25-2011 |
20120041664 | Method for powering an apparatus - An internal combustion engine is coupled to a supercharger operable to supply varying amounts of air to the engine responsive to the load on the engine. The supercharger has a pair of screw rotors driven by the engine to move air to the engine and a control apparatus for varying the mass and pressure of air supplied to the engine. | 02-16-2012 |
20130261518 | BODY PULSATING APPARATUS AND METHOD - A device and method coupled to a therapy garment to apply pressure and repetitive compression forces to a body of a person has a positive air pulse generator and a user programmable time, frequency and pressure controller operable to regulate the duration of operation, frequency of the air pulses and a selected air pressure applied to the body of a person. The air pulse generator has rigid displacers that are angularly moved with crank power transmissions to draw air into the air pulse generator and discharge air pressure pulses to the therapy garment. | 10-03-2013 |

20080269837 | IMPLANTABLE MEDICAL LEAD FOR IMPLANTATION IN A PATIENT, SUCH AS A PATIENT'S NECK - Implantable leads implantable in a patient, such as patient's neck. The lead includes a first lead segment and a second lead segment. The second lead segment extends from the first lead segment at a first junction point and includes first, second, and third legs each defining a longitudinal length in extension from the first junction point to a distal end. A length of the first leg is greater than a length of the second leg, and a length of the second leg is greater than a length of the third leg. With this configuration, each of the legs are adapted to support at least one electrode at the distal end thereof, and are appropriately dimensioned relative to one another for locating the corresponding electrode at a desired target tissue site in the patient's neck. Targeted tissue can include, for example, muscles of the neck. | 10-30-2008 |
20080269856 | IMPLANTABLE MEDICAL LEADS WITH FLEXIBILITY AND EXTENSIBILITY TO FACILITATE BODY MOVEMENTS - Implantable medical leads that are flexible and extensible in a controllable manner to facilitate subject body movements, able to permit and withstand multiple degree of freedom of movement that are useful for use in the neck region of a subject body and other regions of any subject's body that may benefit from increased flexibility and extensibility. Features of medical leads are utilized to permit extensibility and are based upon the provision of shaped features that controllably permit lead extension under low load, but that maintain a desired shape under no load. The shaped lead portions provide extensibility to the lead as the shapes elastically deform under load. A shaping element, such as an elongate element or a tube defines and holds the lead in the desired shape, which may comprise one or more series of sigmoid shapes as a pattern. | 10-30-2008 |
20080269857 | IMPLANTABLE MEDICAL LEADS AND LEAD ASSEMBLIES WITH FLEXIBILITY, EXTENSIBILITY AND BRANCHED STRUCTURES - Implantable medical leads that are flexible and extensible in a controllable manner to facilitate subject body movements and that are bundled to create a branched lead to permit lead body ends on one or both ends of the lead to be movable relative to one another so as to be positionable in different locations. Implantable medical leads advantageously include individual lead portions, sub-bundles, and bundles that are able to be selectively positioned and implanted within a subject body and that are useful, in particular, for use in the neck region of a subject body and other regions of any subject's body that may benefit from increased flexibility, extensibility and positionability. | 10-30-2008 |
20080269858 | IMPLANTABLE MEDICAL LEADS WITH FLEXIBILITY AND EXTENSIBILITY, AND HAVING A SUBSTANTIALLY TWO-DIMENSIONAL NATURE - Implantable medical leads that are flexible and extensible in a controllable manner with a substantially two-dimensional profile to fit between adjacent tissue layers and to facilitate subject body movements. In particular, implantable medical leads able to permit and withstand multiple degree of freedom of movement that are useful for use in the neck region of a subject body and other regions of any subject's body that may benefit from increased flexibility and extensibility. Features of medical leads are utilized to permit extensibility and are based upon the provision of shaped features that controllably permit lead extension under low load, but that maintain a desired shape under no load. The shaped lead portions provide extensibility to the lead as the shapes elastically deform under load. | 10-30-2008 |
20080269859 | METHODS FOR CUSTOMIZING IMPLANTABLE MEDICAL LEADS AND LEAD ASSEMBLIES WITH IMPROVED FLEXIBILITY AND EXTENSIBILITY - Implantable medical leads that are customizable and that are flexible and extensible in a controllable manner to facilitate subject body movements. In particular, implantable medical leads include the ability to be customized by selective and controllable separation of lead bodies from one another, which leads are also able to permit and withstand multiple degree of freedom of movement that are useful for use in the neck region of a subject body and other regions of any subject's body that may benefit from increased flexibility and extensibility. | 10-30-2008 |
20080269861 | IMPLANTABLE MEDICAL LEAD ASSEMBLIES WITH DELIVERY TETHER - Implantable lead assembly including a lead body, an elongated conductor, a coiled electrode, and a tether line. The lead body maintains the conductor. The electrode is coupled to the conductor, defining proximal and distal ends. The tether line defines a trailing segment and a leading segment terminating in a leading end. The tether line is coupled to the coiled electrode at a point proximal the distal end, and the leading end extends distal the distal end. With this configuration, a pulling force applied to the leading segment is transferred to the electrode at a point proximal the distal end as a pushing force, thereby minimizing an opportunity for overt stretching of the coiled electrode during implantation. The lead assembly can further include a needle connected to the tether line. | 10-30-2008 |
