  • Patent number: 8763408
    Abstract: A hybrid thermoelectric-ejector active cooling system having an increased Coefficient of Performance (COP) when compared to typical thermoelectric cooling modules. A thermoelectric cooling module is integrated with an ejector cooling device so that heat from the thermoelectric cooling module is rejected to a high temperature evaporator of the ejector cooling device. This provides for a total COP greater than the sum of the COPs of the thermoelectric cooling module and ejector cooling device individually. For example, given 1 unit input power into the thermoelectric cooling module, the heat received by the cold side of the thermoelectric cooling module would be COPTEC×1; and the energy rejected by the hot side of the thermoelectric cooling module and to drive the ejector cooling device would be COPTEC+1. Thus, the cooling received by the low temperature evaporator of the ejector cooling device is COPEJ×(COPTEC+1); and therefore total COPTE-Ej-AC is COPEj+COPTEC+COPEj×COPTEC.

  • Patent number: 8034291
    Abstract: An apparatus for introducing a reductant into an exhaust system is described. The apparatus includes a controller that generates a resulting dosing command used as an instruction to release an amount of reductant into the exhaust system. The controller includes a feedback control module that generates a weighing factor. The weighing factor is configured to be applied to a lower limit dosing command and configured to be applied to an upper limit dosing command, where the lower and upper limit dosing commands converted by the weighing factor are used by the controller to generate the resulting dosing command.

  • Publication number: 20100212331
    Abstract: A device and method suitable for the cryopreservation of all types of biological cells is described. In this method, an ultra-fast cooling/warming device system is used to achieve vitrification of individual cells or cell suspensions without cryoprotectant agents (CPA) or with a low concentration of CPAs (<1M), to attenuate the formation of intracellular ice crystal formation during cooling, and to minimize devitrification during subsequent warming. The device system applies oscillating heat pipe (OHP) and nanofluid techniques, and is built through microfabrication. Several devices may be networked to increase the total volume of cell samples that the cryopreservation system can process simultaneously.

    Abstract: A system having a particulate matter sensor in an exhaust stream of an engine upstream from a particulate filter and another such sensor downstream from the filter. There may also be an exhaust gas recirculation (EGR) control on the engine. The amount of particulate matter in or loading of the filter may be determined by the upstream filter. The working condition of the filter may be determined by the downstream sensor. The filter may have a heater and control for providing operational and particulate matter burn-off temperatures to the filter. A processor may be connected to the sensors, the EGR control and the filter heater control.
