20150377707 | System And Method For Non-Destructive, In Situ, Positive Material Identification Of A Pipe - A system and method for non-destructive, in situ, positive material identification of a pipe selects three test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/−10%, a carbon percentage within +/−25%, and a manganese percentage within +/−20% of a known material standard. | 12-31-2015 |

20110212303 | PDC Cutter with Stress Diffusing Structures - A PCD cutting element for use in earth boring drill bits where the interstices remote from the working surface are filled with a catalyzing material and the interstices adjacent to the working surface are substantially free of the catalyzing material is described. An intermediate region between the substantially free portion and filled portion has a plurality of generally conically sectioned catalyst-free projections which taper down, extending to a second depth from the planar working surface, preferably about 0.5 times or more of the first depth. | 09-01-2011 |
20120193149 | DRILL BIT WITH ENHANCED HYDRAULICS AND EROSION-SHIELD CUTTING TEETH - Disclosed is a rolling cone drill bit with inner row cutting teeth having portions shielded with an erosion-resistant material that differs in material properties from the tooth's core portion that is more impact resistant. The tooth includes shielding on at least a portion of the upstream end and along portions of the flanking surfaces. It includes shield-free portions on the flanks between the root and the tooth crest. Most of the tooth's perimeter is made of the core material and is free of shielding. Gage row teeth may be angled and form a channel to direct drilling fluid from the gage region of the borehole to locations where the inner row teeth are generating most cuttings. Nozzles are provided with non-uniform orientations. | 08-02-2012 |

20110117294 | Biofouling prevention by induction heating - An apparatus and method for heating target surfaces to a temperature that inhibits, prevents or removes biofouling through induction heating includes an electromagnetic driver and control circuitry for generating electromagnetic energy within a select frequency range to match a target surface. An antenna emits the electromagnetic energy within a focused region to react with atoms/molecules in the target surface, thereby causing the target surface to be heated to a temperature within a controlled range. Increasing temperature sufficiently disrupts, kills or denatures biofouling organisms, biofilms and organic matter on the target surface and/or denatures biofilms on the surface. Coating materials may be applied to target surfaces to optimize the RF reactive molecular structure. A diagnostics, positioning and temperature sensor circuit communicates with the electromagnetic driver. A feedback circuit is used to maintain power level. Contemplated heating mechanisms include: magnetic hysteresis; dielectric hysteresis; eddy currents; and enhanced skin effect. | 05-19-2011 |

20120291042 | MINIMIZING RESOURCE LATENCY BETWEEN PROCESSOR APPLICATION STATES IN A PORTABLE COMPUTING DEVICE BY SCHEDULING RESOURCE SET TRANSITIONS - Resource state sets corresponding to the application states are maintained in memory. A request may be issued for a processor operating in a first application state corresponding to the first resource state set to transition to a second application state corresponding to the second resource state set. A start time to begin transitioning resources to states indicated in the second resource state set is scheduled based upon an estimated amount of processing time to complete transitioning. A process is begun by which the states of resources are switched from states indicated by the first resource state set to states indicated by the second resource state set. Scheduling the process to begin at a time that allows the process to be completed just in time for the resource states to be immediately available to the processor upon entering the second application state helps minimize adverse effects of resource latency. | 11-15-2012 |
20130227583 | Method and System For Scheduling Requests In A Portable Computing Device - A method and system for managing requests among resources within a portable computing device include a scheduler receiving data from a client for scheduling a plurality of requests. Each request identifies at least one resource and a requested deadline. Next, data from the client is stored by the scheduler in a database. The scheduler then determines times and a sequence for processing the requests based on requested deadlines in the requests and based on current states of resources within the portable computing device. The scheduler then communicates the requests to the resources at the determined times and according to the determined sequence. The scheduler, at its discretion, may schedule a request after its requested deadline in response to receiving a new request command from a client. The scheduler may allow a sleep set corresponding to a sleep processor state to power off a processor. | 08-29-2013 |

20120015182 | Adhesive Extrusion For Dynamically Vulcanized Thermoplastic Elastomer Laminates - A coextrusion process for coextruding a thermoplastic elastomer with two outer layers of adhesive to form a film, and a laminate comprising a plurality of layers including an adhesive layer, a sublayer and a barrier layer. The barrier layer comprises a dynamically vulcanized thermoplastic elastomer composition present in one or more plies of the barrier layer. The sublayer comprises a first ply of a first adhesive composition joining the barrier layer and a second ply, and the adhesive layer comprises the second ply, which is vulcanizable with diene-based rubber. The sublayer of the adhesive can be laid down in contact with the relatively hot thermoplastic elastomer to moderate the temperature of the outer layer of the adhesive, whereby the outer layer of the adhesive at least is protected from scorching and can be co-vulcanized with rubber in a tire building process. | 01-19-2012 |

20100085186 | Tamperproof Non-Contact Switch - A non-defeatable magnetically actuatable switch device is shown and described for restricting access to industrial controls. The non-contact switch device employs one or more non-contact access switches, and an access key removably disposed in close proximity to each access switch. Removal or installation of an access key alters the electrical state of a corresponding access switch. A connected control unit determines a mode of operation, or grants permissions, based on the combination of access keys that are present or absent from the device. A lockable or sealable cover is provided over the access keys to limit unauthorized access. A tamper detection switch is also provided for the sole purpose of identifying foreign magnetic sources in the vicinity of the access switches to ensure that the device is non-defeatable. Furthermore, all access and tamper detection switches are magnetically actuatable and thus provide a completely contact-free means of securing and restricting access to sensitive controls and parameters. | 04-08-2010 |
