20130325110 | SYSTEMS AND METHODS FOR PLACING A COAPTING MEMBER BETWEEN VALVULAR LEAFLETS - The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valveāi.e., the mitral valve and the tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. Finally, there is a proximal anchoring feature to fix the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets. | 12-05-2013 |
20140235984 | SYSTEM FOR A BLOOD ANALYTE SENSOR - The present invention provides a blood parameter sensing system that may include a sensor, a blood access system, a flow controller and a monitor system. The blood access system may include a blood draw member having an internal configuration adapted to avoid clotting without the use of anticoagulants and under a range of flow profiles, including small volume blood draws. The flow controller may be configured to adapt to a range of access devices by using feedback from the sensor and monitor to customize flow profiles. The monitor system is configured to reduce parameter measurement error by modeling sensitivity change during system startup or reconnect. | 08-21-2014 |

20150022795 | POWER SUPPLY FOR A DISCHARGE PRODUCED PLASMA EUV SOURCE - A power supply for providing HV power to a lithography illumination source comprising a HV power source arranged to provide the HV power, a HV power transmission line arranged to transmit the HV energy from the HV power source and one or more RF terminations provided on one or more of an input end of the transmission line or an output end of the transmission line. The one or more RF terminations terminate the transmission line to reduce reflection of RF energy at the end of the transmission line. | 01-22-2015 |

20120207255 | METHOD AND APPARATUS FOR REDUCING OR REMOVING CLICK NOISE - The invention relates to an apparatus and a method for detecting and correcting input signals regarding click noise, using a first detector unit and a second correction unit, the detector unit differentiates the input signal and extracts the noise signal and compares the sum of two noise samples with a threshold value and in case this sum exceeds the threshold value a click is observed, while the correction unit corrects the input signal in the phase domain and differentiates it prior to outputting the corrected signal. | 08-16-2012 |
20120243629 | Digital Communications Receiver - A method for a digital Communications receiver. The method comprises receiving a signal transmitted from a transmitter. The transmitted signal includes a first modulated carrier representing one or more data bits and a second modulated modulated carrier optionally representing one or more padding bits only. The padding bits are inserted at the transmitter and have predefined values known to both the transmitter and receiver. The method further comprises determining whether the one or more padding bits were inserted at the transmitter; if so, analysing the second modulated carrier in the received signal, using knowledge of the predetermined values of the one or more padding bits; and, using information determined from the analysis, estimating the values of the one or more data bits from the first modulated carrier. | 09-27-2012 |

20110110849 | METHOD OF CONVERTING A RAW MATERIAL STREAM INTO A PRODUCT STREAM USING A FLUIDIZED BED AND APPARATUS FOR USE IN SAID METHOD - The present invention relates to a method of converting a raw material stream into a product stream by passing said raw material stream through a bed of fluidized solid particles and allowing heat exchange to occur between the bed of fluidized solid particles and the raw material stream, said method being characterized in that it alternately employs a production mode and a restoration mode to control the temperature of the bed of fluidized solid particles: -said production mode comprising passing the raw material stream through the bed of fluidized solid particles and allowing the temperature of the fluidized solid particles in the bed to decrease or to increase as a result of the production energy associated with the conversion of the raw materials stream into the product stream; and -said restoration mode comprising restoring the temperature of the bed of fluidized solid particles by passing a restoration stream through the bed of fluidized solid particles to decrease the temperature of the fluidized solid particles in case the temperature of the fluidized solid particles has increased during the production mode or to increase the temperature of the fluidized solid particles in case the temperature of the fluidized solid particles has decreased during the production mode, and that -the fluidized solid particles are kept in the same reactor. The present method enables continuous operation of the fluidized bed reactor without the need of recirculating externally heated or cooled solid bed particles and/or for special heat exchange equipment placed inside or enclosing the fluidized bed reactor. | 05-12-2011 |
20130011803 | BATCH-WISE OPERATED RETORT USING TEMPORARY STORAGE OF HEAT - A batch of a substance, e.g., a biomass, is processed in a batch-wise operated retort under the application of heat. The substance releases a combustible process fluid during the processing. The process fluid is combusted for generating heat. The heat is supplied to the retort and/or stored in temporary heat storage in dependence on the progress of the processing for postponed heat supply to the retort. | 01-10-2013 |
