20160121134 | MEDICAL DEVICE FOR APPLYING NON-THERMAL PLASMA TO SELECTED TARGETS - A medical device for directly applying DBD plasma includes a plasma generation module having an electrode surrounded by a dielectric barrier. In one embodiment, when a high voltage source is applied to the electrode, plasma is produced from ambient gas on an outside surface of the plasma generation module. In another embodiment, an enclosure is deployed around the distal end of the plasma generation module surrounding the electrode. Gas flows past the electrode and into the enclosure. In some embodiments, some or all of the gas is removed or pumped out of the enclosure by suction/vacuum. When a high voltage source is applied to the electrode, plasma is produced using the gas flowing into the enclosure. | 05-05-2016 |

20150145255 | METHOD AND SYSTEM FOR ALTERNATOR THERMAL PROTECTION - A system (for controlling cooling of an alternator) comprises a control system, an alternator, and a blower fan, the alternator having a stator and a rotor. The control system is adapted to estimate one or more temperatures of the stator and/or rotor of the alternator using a thermal model. The control system is also adapted to control the blower fan to cool the alternator by providing a specified amount of air flow across the stator and rotor of the alternator, based on the estimated one or more temperatures of the stator and/or rotor. | 05-28-2015 |

20150314997 | CABLE BREAKAGE DIAGNOSIS IN A CRANE - A crane has a base, an adjustable-length boom pivotal on the base and formed by at least one outer boom element and at least one inner base-mounted boom element telescoping with the outer element, and a cable extending between an outer end of the outer boom element and the inner boom element so as to be pulled out on extension of the outer boom element from the inner boom element. Such a crane is operated by detecting tension in the cable and generating an output corresponding thereto, determining when the tension in the cable is outside a predetermined noncritical range, and taking action to suspend operation of the crane on determination that the tension is outside the noncritical range. | 11-05-2015 |

20150290280 | ANTIMICROBIAL ARTICLES PRODUCED BY ADDITIVE MANUFACTURING - An antibiotic-eluting article for implantation into a mammalian subject, produced by an additive manufacturing process wherein a polymeric material is concurrently deposited with a selected antibiotic. The additive manufacturing process may be a fused deposition modeling process, a selective laser sintering process, a selective heat sintering process, a digital light processing process, or a stereolithography process. The antibiotic-eluting article may be temporary or permanent orthopaedic skeletal component, an orthopaedic articulating joint replacement component, and/or an external hard-shell casing for an implantable device. One or more bone-growth-promoting compositions may be concurrently deposited with the polymeric material. The implantable device may be a cardiac pacemaker, a spinal cord stimulator, a neurostimulation system, an intrathecal drug pump for delivery of medicants into the spinal fluid, and infusion pump for delivery of chemotherapeutics and/or anti-spasmodics, an insulin pump, an osmotic pump, and a heparin pump. | 10-15-2015 |
