20090301883 | METHOD AND SYSTEM FOR CONCENTRATING PARTICLES FROM A SOLUTION - Methods and systems are provided for concentrating particles (e.g., bacteria, viruses, cells, and nucleic acids) suspended in a liquid. Electric-field-induced forces urge the particles towards a first electrode immersed in the liquid. When the particles are in close proximity to (e.g., in contact with) the first electrode, the electrode is withdrawn from the liquid and capillary forces formed between the withdrawing electrode and the surface of the liquid immobilize the particles on the electrode. Upon withdrawal of the electrode from the liquid, the portion of the electrode previously immersed in the liquid has particles immobilized on its surface. | 12-10-2009 |
20140150464 | Temperature-Stabilized Storage Systems with Integral Regulated Cooling - In some embodiments, a regulated thermal transfer device for a storage container includes: a phase change material unit, the phase change material unit including one or more walls surrounding a phase-change material region, and an aperture in the one or more walls; a heat pipe with a first end positioned within the phase change material unit, and a second end; a thermoelectric unit thermally connected to the second end of the heat pipe; a heat sink connected to the thermoelectric unit, and positioned to radiate heat away from the thermoelectric unit; and an electronic controller operably connected to the thermoelectric unit; wherein the regulated thermal transfer device is of a size and shape to be positioned so that the phase change material unit is within a storage region of a temperature-stabilized storage container, and the thermoelectric unit is positioned adjacent to an external surface of the temperature-stabilized storage container. | 06-05-2014 |
