20100011760 | Hydraulic heat engine utilizing heat of compression and having independent control loop - A high performance modular heat engine is presented that uses a highly pressurized working gas and hydraulic fluid within a pipeline or flow circuit to produce power hydraulically. It does this by adding heat to the working gas via a control loop, isolated from the power producing working gas and hydraulic fluid, to increase its pressure and impart movement to said hydraulic fluid. The heat engine can utilizes its working gas' heat of compression to improve its performance by removing it during compression and returning it to the working gas during expansion. The engine can use momentum developed internally to convert low temperature heat into high temperature heat to boost its efficiency and performance by creating an artificial high ΔT between its heat source and heat sink. | 01-21-2010 |

20160056838 | Digital Technique For Excess Loop Delay Compensation In A Continuous-Time Delta Sigma Modulator - A continuous time delta sigma modulator includes a quantizer, a buffer module, and a reference module. The quantizer includes a comparator that updates a digital output each cycle of a clock signal based on a comparison of a reference potential with an input generated based on a sample of an analog signal. The buffer module receives the digital output, stores the digital output for a predetermined delay period, and outputs the digital output after the predetermined delay period as a delayed digital output. The predetermined delay period is less than one cycle of the clock signal. The reference module selectively varies the reference potential based on the delayed digital output. | 02-25-2016 |

20090162930 | ACTIVE GRIP FILTER PLUG FOR SAMPLE COLLECTION DEVICES - A system for collecting a biological sample includes a collection device comprising a cylindrical body having a bore extending there through and a filter membrane disposed at one end thereof; a filter plug having an insert configured for insertion into the bore; a collar concentrically mounted about the exterior surface of the insert and configured for insertion into the bore; and a gasket disposed about the exterior surface of the insert, wherein an outer dimension of the gasket is variable in response to relative movement between the collar and the insert, and wherein the gasket has a cross section with two end portions and a mid portion that is located radially further away from the insert than the two end portions. | 06-25-2009 |
20090312955 | METHOD AND APPARATUS FOR CALIBRATING FILTERS DURING SPECIMEN COLLECTION - A bubble point of a combination of a filter and a liquid is calibrated by applying an initial back pressure through the filter toward the liquid; taking a first plurality of measurements of the level of the liquid in the container; calculating a first variance of the first plurality of measurements; and comparing the first calculated variance with a known threshold variance. Then a second plurality of measurements of the level of the liquid in the container is taken; a second variance of the second plurality of measurements is calculated; and the second calculated variance is compared with a known threshold variance. The above described steps are repeated at incrementally increased back pressures until the first and second calculated variances are each greater than or equal to the known threshold variance, which is about 0.01. The bubble point is determined to be the back pressure at that point. If the determined bubble point is less than or equal to the known threshold bubble point, which is about 0.8 pounds per square inch, the filter is identified as unsuitable for use in cell block formation. | 12-17-2009 |
20100112629 | CELL BLOCK CASSETTE DEVICE - A tissue cassette assembly includes a housing having a recess formed therein, and a compressible reservoir disposed partially or wholly inside of, or otherwise attached in fluid communication with, the housing recess, the compressible reservoir containing a tissue embedding material. The tissue cassette further includes a port disposed in the housing, the port in fluid communication with the compressible reservoir at one end and terminating in a sample cavity at another end. During operation, the compressible reservoir is compressed or squeezed to release the tissue embedding material into the sample cavity containing the biological sample. | 05-06-2010 |
20100330660 | CELL BLOCK PROCESSING STATION - A system for making cell blocks includes a cell block cassette and processing station, the cassette including a main body having a having a collection aperture formed therein and a filter assembly removably attached to the main body, the filter assembly defining a collection well in communication with the collection aperture, and having a filter positioned across a bottom surface of the collection well, the filter configured to retain cellular matter carried in a fluid that is dispensed into the collection well and flows across the filter. The cell block processor has a cassette interface removably seating the cell block cassette, and a sensor positioned or positionable to detect and monitor a fluid level in the collection well. The processing station includes an automated fluid delivery system operable to dispense a fluid into the collection well, and a controller operatively coupled to the fluid delivery system, wherein the controller causes the fluid delivery system to selectively dispense fluids into the collection well based at least in part on a flow rate across the filter determined at least in part based on changes in the monitored fluid level in the collection well. | 12-30-2010 |
20140194777 | SWAB ASSEMBLY FOR SPECIMEN COLLECTION - A swab assembly for collecting a specimen from a patient includes an elongated shaft having a proximal end, a distal end, and a notch between its proximal and distal ends; a sheath having a proximal end, a distal end, and a lumen extending between its proximal and distal ends, wherein a portion of the elongated shaft is disposed within the sheath lumen, and the sheath is slidable relative to the elongated shaft; and a collection tip coupled to the distal end of the elongated shaft and configured for obtaining the specimen. The sheath is slidable between a first position in which the shaft notch is disposed within the sheath lumen and wherein the sheath protects the elongated shaft from breaking at the notch, and a second position in which the shaft notch is exposed out of the sheath lumen. | 07-10-2014 |
