20090014158 | Nano shower for chip-scale cooling - A nano shower cools a chip when a coolant sprays onto the chip package from an array of electro spray nozzles. Ideally, the coolant is not conductive and otherwise not harmful to electronics. As such, perfluorocarbons are ideal coolants. Distilled water also works in certain applications. A voltage difference between the coolant and chip package causes the coolant to spray from the electro spray nozzles onto the chip package. The coolant cools the chip package by evaporating or by absorbing heat and flowing away. | 01-15-2009 |
20090019913 | GAS SENSOR TEST AND CALIBRATION SYSTEM - A system for testing and calibrating gas sensors with gas stored in a strip of packets. The strip may be fed into a chamber having a defined volume of air. A packet may be punctured with a mechanism to release one or more gases into the volume of air to result in an air-gas mixture. New air may be moved into the chamber to push the mixture out of the chamber to a sensor for testing and/or calibration. Then another packet may be punctured to release one or more gases into the volume of new air in the chamber for another air-gas mixture. This mixture may be moved out of the chamber, in the same manner as the previous mixture, to another sensor for testing and/or calibration. This procedure may be repeated with additional packets on the strip. | 01-22-2009 |
20090056418 | Method and System for Groundwater Contaminant Monitoring - A method and system for groundwater contaminant monitoring is described. Groundwater is pumped to a stage above the groundwater table where at least a portion of the groundwater is vaporized. The vapor is sampled using cavity ring down spectrometer and the measured vapor concentration of a contaminant is converted to a liquid contaminant concentration. | 03-05-2009 |
20090078657 | DEVICE FOR SEPARATION OF PARTICULATES FROM A BIOLOGICAL SAMPLE - A device for separating plasma from blood cells involves a separation fiber having one or more characteristics such as a high silica content, a low boron content, and/or no binder. | 03-26-2009 |
20090123297 | Microfluidic osmotic pump - A micro-fluidic osmotic pump capable of delivering a desired fluid at a predetermined destination comprising an inside fluid reservoir housing a compressible sac, a surrounding compartment having an external surface made up of a semi-permeable membrane and a fluid duct. The inside fluid reservoir houses a compressible sac containing a predetermined amount of a fluid that is desired to be pumped to a predetermined destination. The surrounding compartment holds a desired osmotic agent and its saturated solution in the remaining volume thereof. The surrounding compartment has an outer surface made up of a semi-permeable membrane that allows a predetermined second external fluid to permeate into the surrounding compartment. The fluid duct is substantially housed within the inside fluid reservoir and runs through openings and respectively provided through the inside fluid reservoir and the surrounding compartment. | 05-14-2009 |
