| 20110030651 | DUAL CRANKSHAFT INTERNAL COMBUSTION ENGINE - A dual crankshaft internal combustion engine having two rotating offset crankshafts respectively attached to connecting rods. Each of the connecting rods, in turn, are pivotally attached to piston rods, which are located an equidistance between the crankshafts. The piston rods are attached to a piston reciprocally disposed in a cylinder. The crankshafts are aligned in parallel and are geared together, either directly or indirectly, thus causing the crankshafts to rotate in the same or opposite directions, depending upon the linkage gear configuration. The dual crankshaft internal combustion engine utilizes leverage from the wedge-effect of the offset crankshafts to provide increased torque, power duration and fuel efficiency. | 02-10-2011 |

| 20100049020 | MULTIPLE WAVELENGTH SENSOR EMITTERS - A physiological sensor is adapted to removably attach an emitter assembly and a detector assembly to a fingertip. The emitter assembly is adapted to transmit optical radiation having multiple wavelengths into fingertip tissue. The detector assembly is adapted to receive the optical radiation after attenuation by the fingertip tissue. The sensor has a first shell and a second shell hinged to the first shell. A spring is disposed between the shells and urges the shells together. An emitter pad is fixedly attached to the first shell and configured to retain the emitter assembly. A detector pad is fixedly attached to the second shell and configured to retain the detector assembly. A detector aperture is defined within the detector pad and adapted to pass optical radiation to the detector assembly. A contour is defined along the detector pad and generally shaped to conform to a fingertip positioned over the detector aperture. | 02-25-2010 |

| 20090156913 | CERAMIC EMITTER SUBSTRATE - A ceramic emitter substrate has a substrate body with top and bottom sides and a cavity disposed on the top side. Bonding pads are disposed within the cavity and solder pads are disposed on the bottom side. Light emitting diodes (LEDs) are electrically connected to the bonding pads. Low-resistance conductors are disposed within the ceramic substrate body so as to interconnect the bonding pads and the solder pads. The interconnect is configured so that the LEDs can be individually activated as an array via row and column drive signals applied to the solder pads. | 06-18-2009 |

| 20090121950 | OPTICAL FIBER COUPLED ANTENNA CURRENT MONITOR - A system for sensing the amplitude and phase of an RF current flowing in an antenna element of a directional antenna system that uses a sampling device such as a current sample loop that is connected to an antenna monitor with fiber optic cable. The system uses an interface at the current sample loop on each of the antenna elements to convert an RF current sample to an optical signal. The fiber optic cable transmits the optical signal to the antenna monitor where it is converted back to an electrical signal for appropriate phase and amplitude comparison with the RF currents sampled from other antenna elements in the directional antenna system. | 05-14-2009 |

| 20100222668 | GUIDANCE AND IMPLANTATION OF CATHETERS - A catheter system adapted for navigating, guiding and implanting a catheter or a plurality of catheters in a spatially-defined implantation within the tissue of a patient is provided. The system can include a tissue navigation system and a probe to inform the navigation system to guide emplacement of the catheters within a target tissue. The probe can provide images, such as fiberoptic visual images, or ultrasound images, or can provide radiolocation data, to guide the catheter emplacement. The catheters supply a pressurized liquid including a bioactive agent, such as can be used in the treatment of cancer, for example 123I- or 125I-IUDR. The system and methods provided can be used in the treatment of locally advanced tumors, such as cancers of the brain, head or neck, esophagus, prostate, ovary, liver, pancreas, bladder or rectum. | 09-02-2010 |
| 20110135569 | METHOD FOR THERAPEUTIC ADMINISTRATION OF RADIONUCLEOSIDES - Methods are provided for the local radiotherapy of cancers such as locally invasive, advanced stage solid tumors, and normal tissues penetrated by processes of cancerous tissue, through administration of Auger-electron emitting radionucleoside analogs using high-flow microinfusion techniques (“convection-enhanced delivery”). Direct infusion under pressure, at flow rates in excess of at least about 0.5 microliters/min of the radionucleosides provides for their mass transport through tissue to a much higher degree than could be achieved by passive, unpressurized diffusion. The unique properties of these radionucleoside analogs that provide for surprisingly effacacious delivery by high-flow microinfusion include rapid clearance from tissues following local injection without the benefit of sustained high-flow microinfusion, rapid and complete clearance via the blood stream, poor permeation of barriers such as the blood-brain barrier, and a highly potent, non-selective, but very short range killing effect on cells that are undergoing DNA replication that incorporate radionucleosides into their chromosomes. | 06-09-2011 |
