  • Cooling system for a vehicle drive assembly
    Patent number: 8063519
    Abstract: A cooling system for use in a vehicle drive assembly having an electric drive with a rotor and a stator is disclosed. The cooling system is adapted to cool the rotor via a liquid coolant or by directing a cooling air flow between the rotor and stator using an independent control capable of independent operation.
    Type: Grant

  • Microassay device and methods
    Patent number: 6224831
    Abstract: The subject invention relates to a rapid, field-portable, modular, versatile and highly reliable assay device for substances, particularly drugs of abuse, which provides a positive signal in the presence of a specific substance for which the device has been specifically adapted to test. The subject invention also concerns methods for making and using the assay device. The device is easily and reliably manufactured by laminating a series of manufactured layers to each other to form an upper card assembly and a lower card assembly. The upper card assembly is bonded to the upper side of a layer which has an immobilized reagent specific for a test substance bound thereto, and the lower card assembly is bonded to the lower side of the layer having the immobilized reagent. The device can be manufactured and distributed in a unitary, ready-to-use form.
