摘要： An assembly that enables precise mounting of a sensor with improved heat transfer and rotation compensation includes an integrated dewar cooler assembly incorporating the sensor. The dewar assembly is mated to a motorized mount that is controlled to stabilize the rotation of the scene. The sensor is radially aligned relative to the axis of rotation in two adjustment stages. A first stage of adjustment controls the radial position of the sensor inside a bearing. And a second stage of adjustment controls radial translation of the entire assembly outside the bearing. Passive heat transfer is accomplished through a pair of heat sinks that effectively sandwich a hot expander end cap of the dewar, providing multiple heat paths. The entire dewar assembly is rotated during operation to stabilize the scene. The rotating mass of a cooling compressor coupled to the dewar is counter-balanced to avoid torque due to inertia.

摘要： The present invention relates to a cryogenic cooler's expander supported by a support member, preferably a truncated conical tube. The support member provides additional stiffness to the expander to reduce movements at the distal end of the expander. The support member also increases the natural frequency of the expander. In one embodiment, the support member increases the natural frequency of the expander at least about two (2) times in the bending and/or twisting sense. In another embodiment, the bending natural frequency of the expander and support sub-assembly is at least about two times greater or lower than the natural frequency of the electrical wires that connect the infrared sensor to a control processing unit to reduce the maximum stress applied to the electrical wires during use. In another embodiment, additional or redundant electrical pathways are provided for the connection between the infrared sensor and the CPU. Furthermore, shock absorber and/or shock diverters are provided on the rigid pins that connect the electrical wires to the CPU.

摘要： A hollow dipstick is provided for immersion in molten material to determine the temperature of the molten material at any desired depth. The hollow dipstick is connected to an infrared detector by means of an optical fiber bundle for producing a signal indicative of the temperature of the molten material. An infrared focusing lens is provided within the hollow dipstick for transmitting the infrared radiation from the interior bottom surface of the dipstick to the fiber optic bundle. A container having a heating element therein is provided for receiving the dipstick when it is not in use so as to preheat the dipstick to a temperature close to the estimated temperature of the molten material to be measured to thereby prevent thermal shock to the dipstick upon immersion in the molten material. Alternatively the infrared detector is mounted directly on the dipstick.

摘要： A distance and temperature sensing unit is used on paving vehicles. The unit has a first set of range sensors of a first diameter and a second set of range sensors of a second diameter. The unit calculates a weighted average distance to a road surface based on ranges measured by the multiple sensors. The unit also has a temperature sensor on a temperature bar. The bar is affixed to the unit by a flexible connection preventing break-off when the bar encounters obstacles, like the road surface, while the paving vehicle is moving.
