  • Patent number: 6781056
    Abstract: Circuit boards (1100, 1500, 1600, 1700) and methods for fabricating circuit boards that include heaters for maintaining temperature sensitive components at an operating temperature are provided. Resistive traces (602, 702,704) are included in the circuit boards proximate temperature sensitive apparatus (1004, 1304, 1602, 1712). Thermally conductive patches (802, 902, 904) are interposed between the resistive traces and the temperature sensitive components. The thermally conductive patches establish zones of relatively uniform temperatures. According to a preferred embodiment of the invention the temperature sensitive apparatus comprises a fluid conduit (1004).

  • Patent number: 6756223
    Abstract: An electro-chemical analysis device and method for analyzing biomolecular samples, including a means for holding a sample on a substrate platform, a thermal sensor, a biosensor formed having a specific spatial resolution as related to the thermal sensor, and a means for providing radiation to the biomolecular sample. The means for holding the sample, the thermal sensor, the biosensor, and the means for providing radiation all three-dimensionally integrated with the substrate platform, thereby defining a compact biomolecular analysis device having a volume resolution of less than 50 micro liters. During operation, radiation is provided to the biomolecular sample to provide for a constant temperature at which hybridization of the biomolecules takes place. The temperature of the biomolecular sample is monitored and controlled by the integrated thermal sensor and the integrated heater. Once hybridization takes place, the change in electric condition (e.g.

  • Publication number: 20040121455
    Abstract: A monolithic ceramic bioreactor for manipulating biofluids at a low flow having formed therein at least one fluid passageway, at least one electromagnetic pathway defined by a high &mgr; magnetic material and an electrically conducting microcoil, a first and second electrode, and a biofluid comprising at least one chemical specie within a buffer solution for preserving the activity of an enzyme contained within a bioassay for genetic reaction. The device is characterized as generating a magnetic field and an electric field, perpendicular to the magnetic field, when under the application of a first and second current. In combination the magnetic field and the electric field characterized as generating a Lorentz force. The biofluid includes sufficient conductivity for fluid motion when under the influence of the Lorentz force generated within the monolithic structure, thereby providing for the manipulating of the biofluid through the monolithic structure.

  • Patent number: 6116863
    Abstract: A microactuated device and method of making the same in which an electromagnetic driver, overlapping a magnetically permeable diaphragm, is utilized to drive the microactuated device. Through the use of an electromagnetic driver to provide the motive force for a microactuated device, exceptional performance may be realized, e.g., with a substantially reduced drive voltage for micropumps, microvalves, and the like, and with stronger and more precise sensory outputs for microactuated sensors and the like. Moreover, by overlapping the electromagnetic driver over a diaphragm, a number of batch processing techniques, each of which is well suited for mass production, may be used in the fabrication of extremely compact and cost effective integrated devices.
