Publication number: 20110179879Abstract: A multi-range pressure sensor apparatus and method that provide multiple signal paths for detecting a broad range of pressures with a high accuracy. A pressure transducer can be configured to include the use of a pressure sense die with piezoresistive elements integrated into the sensor die and in a Wheatstone bridge configuration. A sensed output signal from the sense die can be transferred to one or more amplifier circuits. A programmable compensation circuit can be utilized to multiplex different amplified output signals from each of the amplifier circuits and to provide a digital output. A memory associated with the programmable compensation circuit provides separate compensations, which are stored for each of the different signal paths and removes errors due to amplifier gain and offset.Type: ApplicationFiled: March 22, 2011Publication date: July 28, 2011Applicant: HONEYWELL INTERNATIONAL INC.Inventor: Ian Bentley

Publication number: 20110179881Abstract: In a method for determining mass flow with a Coriolis mass flow measuring device arranged on a rotary filler, a correction value ?{dot over (m)} is ascertained, which is proportional to the RPM n of the rotary filler. This correction value is subtracted from the conventionally ascertained value {dot over (m)} of the mass flow. The corrected measured value {dot over (m)}corr is thus {dot over (m)}corr={dot over (m)}??{dot over (m)}.Type: ApplicationFiled: August 31, 2007Publication date: July 28, 2011Applicant: Endress + Hauser Flowtec AGInventors: Gerhard Eckert, Christian Matt, Matthias Altendorf

Publication number: 20110179883Abstract: A tunable nanoscale resonator has potential applications in precise mass, force, position, and frequency measurement. One embodiment of this device consists of a specially prepared multiwalled carbon nanotube (MWNT) suspended between a metal electrode and a mobile, piezoelectrically controlled contact. By harnessing a unique telescoping ability of MWNTs, one may controllably slide an inner nanotube core from its outer nanotube casing, effectively changing its length and thereby changing the tuning of its resonance frequency. Resonant energy transfer may be used with a nanoresonator to detect molecules at a specific target oscillation frequency, without the use of a chemical label, to provide label-free chemical species detection.Type: ApplicationFiled: February 11, 2011Publication date: July 28, 2011Applicant: The Regents of the University of CaliforniaInventors: Alex K. Zettl, Kenneth J. Jensen, Caglar Girit, William E. Mickelson, Jeffrey C. Grossman

Publication number: 20110179884Abstract: The invention provides a test rig for testing blades for a wind turbine, the test rig comprising a fixing structure where a root end of a wind turbine blade can be fixed, a loading mass structure extending from the fixing structure, and an actuation structure which can apply a sinusoidal force to the loading mass structure so that a counterbalanced resonance is established between the loading mass structure and a blade which is fixed in the fixing structure. Due to the counterbalanced resonance, the force from the test rig onto the floor or other building components can be reduced relative to that known from the traditional rigs for blade testing.Type: ApplicationFiled: June 30, 2009Publication date: July 28, 2011Applicant: VESTAS WIND SYSTEMS A/SInventor: Stuart Guy

Publication number: 20110179886Abstract: A compressive force measurement device with a pressure-/voltage converter in chip technology features a spherical segment-shaped sensor area. The pressure-/voltage converter is disposed between one base disc and one cover disc, wherein the base disc and the cover disc are tensioned against one another by means of springs with essentially identical pulling force. Forces acting on the cover disc have the effect that the cover disc always positions itself perpendicularly to the direction of force, whereby some of the springs are additionally loaded and others are relieved and thereby a compensation of forces takes place that act obliquely on the compressive force measurement device.Type: ApplicationFiled: January 25, 2011Publication date: July 28, 2011Applicant: INNOVATIONS-TRANSFER UPHOFF GMBH & CO.

Publication number: 20110179887Abstract: A sample acquisition device includes a body comprising a plurality of sample acquisition regions defined by at least a first wall and a second wall oriented nonparallel to the first wall. In some embodiments, the body defines a plurality of apertures that define a plurality of sample acquisition regions. In other embodiments, the walls extend from the body, and the sample acquisition regions are defined between the walls. The sample acquisition regions may be configured in some embodiments such that a user may acquire a sample by rotating the body in a first direction relative to a sample source and may release the sample by rotating the body in a second direction that is substantially opposite to the first direction. When rotated in the first direction, at least one of the first or second walls defines a surface that is inclined into a sample acquisition region.Type: ApplicationFiled: February 12, 2009Publication date: July 28, 2011Inventors: Paul J.

Publication number: 20110179888Abstract: Device, system and method for sampling of soft sediments with retention of sample material and profile. A barge is anchored and stabilized in position; sampling tubes are driven through underlying sediments using continuous and controllable translational pneumatic force; a torpedo-shaped end piece leads the sampling tubes into the sediments. Once at desired depth, a rotational force is applied to sampling tubes. Fins located around torpedo prevent the torpedo from rotating and connection between leading sampling tube and torpedo is tightened. O-ring located between torpedo and leading sampling tube is squeezed as a result of such tightening and bulges inward pinching the core inside sampling tube. During retrieval, core is more likely to break at the location of the pinch which has introduced structural discontinuity; core above the pinch is capped by compacted material at the pinch. O-ring does not disturb sample integrity during descent. Winch and pulley mechanism may assist.Type: ApplicationFiled: January 28, 2010Publication date: July 28, 2011Inventor: Bijan Danesh
