20150207160 | Fuel Cell Apparatus, Composition and Hydrogen Generator - A fuel cell apparatus comprises fuel cells, hydrogen generators and a control unit. A fuel cell array comprises a plurality of membrane electrode assemblies (MEAs) each having a major planar surface; the MEAs are arranged such that a first surface of a first MEA which is not a major planar surface of the first MEA faces a second surface of a second MEA which is not a major planar surface of the second MEA. A plurality of fuel cells, for example arranged in an array, are included in a blade, which is connected externally to the control unit. The apparatus can accommodate a plurality of blades. A closed reactor for the generation of hydrogen gas from a chemical hydride comprises a reaction vessel; at least one entry port; and an outlet port for outputting hydrogen gas. A unit form of a composition comprises a chemical hydride; the unit form has a volume of at least 0.01 cm3. | 07-23-2015 |

20130281805 | METHOD AND SYSTEM FOR DETECTION OF RESPIRATORY VARIATION IN PLETHYSMOGRAPHIC OXIMETRY - A method and system for detection of pulsus paradoxus are provided. In one embodiment, the method includes determining a power spectrum density for a plethysmographic waveform and identifying pulsus paradoxus based on the power spectrum density. The power spectrum density may include a first wave peak indicative of a respiratory rate and a second wave peak indicative of a heart rate. Pulsus paradoxus can be identified by comparing a height of the first wave peak and a height of the second wave peak. | 10-24-2013 |

20150300159 | Apparatus and Method for Evaluating Cement Integrity in a Wellbore Using Acoustic Telemetry - An electro-acoustic system for downhole telemetry employs a series of communications nodes spaced along a string of casing within a wellbore. In one embodiment the nodes are placed within the cement sheath surrounding the joints of casing and allow wireless communication between transceivers residing within the communications nodes and a receiver at the surface. The transceivers provide node-to-node communication up a wellbore at high data transmission rates for data indicative of cement sheath integrity. A method of evaluating a cement sheath in a wellbore uses a plurality of data transmission nodes situated along the casing string which send signals to a receiver at the surface. The signals are then analyzed. | 10-22-2015 |

20090320259 | SWAGE COLLAR WITH INTERNAL SEALING INSERT - A swage collar and an internal sealing insert form a swage collar assembly used in combination with a structural fastener to prevent leakage through a connection of workpieces fastened together by the structural fastener. The swage collar has a hollow, generally cylindrical main body portion with a main central bore, and a base portion with an internal shoulder formed in the main central bore so as to form a seal receiving guide. The shaft of the fastener typically includes a threaded section and an unthreaded section, and the internal sealing insert interfaces with the threaded section and the unthreaded section of the shaft of the pin. In an alternate embodiment, the internal sealing insert interfaces with the unthreaded section of shaft of the pin. The swage collar assembly is fitted over the fastener, a swaging tool is fitted over the swage collar assembly, and the swaging tool is forced over the swage collar assembly with sufficient force to cause plastic deformation in the swaging collar to force the swaging collar and internal sealing insert into engagement with the shaft of the fastener. | 12-31-2009 |
