  • Patent number: 7435993
    Abstract: An electronic package designed to package silicon carbide discrete components for silicon carbide chips. The electronic package allows thousands of power cycles and/or temperature cycles between ?55° C. to 300° C. The present invention can also tolerate continuous operation at 300° C., due to high thermal conductivity which pulls heat away from the chip. The electronic package can be designed to house a plurality of interconnecting chips within the package. The internal dielectric is able to withstand high voltages, such as 1200 volts, and possibly up to 20,000 volts. Additionally, the package is designed to have a low switching inductance by eliminating wire bonds. By eliminating the wire bonds, the electronic package is able to withstand an injection mold.

  • Patent number: 4737139
    Abstract: A unitary device for the treatment and collection of blood from two different sources during a surgical procedure comprises a hollow housing made of a rigid, preferably transparent, material, first and second blood inlets in the housing, a first blood treatment element inside the housing comprising a layer of porous defoaming material and a layer of non-woven depth filter material, and a second blood treatment element inside the housing comprising a layer of porous defoaming material and free of any depth filter material. The novel device also includes internal walls for providing two blood flow paths therein, one through the first inlet, the first blood treatment element, a blood collection reservoir defined within the device and a treated blood outlet in the bottom wall of the housing, and the other through the second inlet, the second blood treatment element, the blood collection reservoir and the blood outlet.
