  • Publication number: 20150138731
    Abstract: A cooling apparatus is disclosed, which may include multiple heat producing units. The cooling apparatus may also have a thermal interface material (TIM) to facilitate heat transfer away from the heat producing units. The cooling apparatus may also have multiple heat sink columns located above, and designed to conduct heat away from, corresponding heat producing units, through thermally conductive contact with corresponding portions of the TIM layer. The cooling apparatus may also have a load plate located above the heat sink columns, designed to hold the heat sink columns in a relatively fixed position above the heat producing units. The TIM layer may have an initial compressed state between the heat sink columns and the corresponding heat producing units. Each of the heat sink columns may be designed so that, in operation, the corresponding portion of the TIM layer may have a further compressed state.

  • Patent number: 8705050
    Abstract: A mechanism for providing thermal compensation when measuring surface topography at an elevated temperature using a non-contact vibration transducer, such as a laser Doppler vibrometer (LDV). Thermal compensation is provided to a detector output signal to correct for thermal diffraction of a reflected portion of a beam of radiant energy directed at a surface of a test object. The thermal compensation is based on a calculated deviation between the detector output signal r2 at an elevated temperature and the detector output signal r1 at approximately room temperature.
