  • Patent number: 8628240
    Abstract: Various embodiments provide systems and methods measuring the temperature of a device using a semiconductor temperature sensor, such as a diode. This invention allows the use of an uncalibrated diode to be used as a temperature sensor by applying a sinusoidally varying forcing current to the diode and measuring the rate of change of the voltage across the diode. Embodiments advantageously provide for a rapid, responsive temperature measuring, substantially eliminating the effect of lead resistance associated with the temperature sensor.

  • Patent number: 7373967
    Abstract: A mechanical assembly for regulating the temperature of an IC-chip in an IC-module includes: a) a heat-exchanger having a first face for contacting a second face on the IC-module; and b) a gimbal, coupled to the heat-exchanger, for tilting and pressing the first face flatly against the second face, as the first and second faces are moved from a spaced-apart position to an engaged position at which the IC-chip temperature is regulated. In addition, the mechanical assembly further includes an output tube, coupled to an output port on the heat-exchanger, which has two ends that move relative to each other as the first and second faces move from the spaced-apart position to the engaged position; and, this output tube is coiled into a weak spring which is characterized by a stiffness matrix that is limited by a predetermined acceptance criterion.
