摘要： Apparatus for detecting intracranial temperature and blood oxygenation includes a transducer having a working surface for placement against a patient's cranium. The transducer forms a microwave antenna having walls defining an aperture having a pair of opposite broader boundaries and a pair of opposite narrower boundaries at the working surface. The antenna is tuned to a frequency which produces a first output signal indicative of heat emanating from the cranium. An oxygen saturation sensor sharing that aperture includes a radiation emitter located at one of narrower boundaries which directs electromagnetic radiation across the aperture to a radiation detector at the other of the narrower boundaries and which produces a corresponding second output signal. A control unit includes a display and a processor for processing the signals to calculate an intracranial temperature and an oxygen saturation value for display by the control unit.

摘要： A method for measuring the contact force exerted on tissue by a probe for heating the tissue and containing an antenna which is connected to a radiometer whose output reading indicates the temperature at depth of the tissue contacted by the probe comprises displaying the output reading of the radiometer, applying sufficient power to the probe to heat the tissue to a selected first temperature that is not lethal to the tissue, moving the probe into contact with the tissue, observing the increase in the displayed temperature reading that occurs when the probe contacts the tissue, and advancing the probe toward the tissue until the displayed temperature reading reaches a value corresponding to a selected tissue contact force. After the probe position in the tissue has stabilized, the applied power to the probe may be increased to heat the tissue to a selected second temperature that is lethal to tissue for a sufficient time to ablate the tissue followed by lowering the tissue heating to a sub-lethal temperature. Apparatus for practicing the method is also disclosed.

摘要： A micro-electro-mechanical device including a first substrate; a first contact disposed on a first surface of the substrate; a piezoelectric actuator disposed over the first surface of the substrate; a second contact coupled to the actuator and disposed in proximity to the first contact; a gap control mechanism disposed between the substrate and the actuator for limiting movement of the first contact relative to the second contact. In the exemplary embodiment, the gap control mechanism is a gap control stop constructed of dielectric material. In practice, plural stops are used. In the exemplary embodiment, plural thermosonic bonds are used to connect the actuator to the first substrate. A second substrate is disposed over the piezo-electric actuator. The second substrate has wells over the bonds to facilitate application of a bonding tool to the bonds. The gap control mechanism provides consistent height control between a flipped chip and its base substrate without exposing the assembly to high temperatures.
