摘要： A system for heat treating a part includes an oven chamber, a first infrared (IR) emitter configured to deliver a first amount of IR energy to a first region of the part, a second IR emitter configured to deliver a second amount of IR energy different from the first amount of energy to a second region of the part, and a receiver with an outer surface configured to contact a second surface of the part and shield the second surface of the part from infrared radiation. The part can be heat treated by delivering different amounts of IR energy to the first and second regions of the part. The system can be used to heat treat different thicknesses of a part without overheating a thinner region, or to apply different heat treatments to the different regions.

摘要： A low-noise alternating current sensor enables low-cost, large dynamic range current measurements of low-frequency alternating current flows. The low-noise current sensor offers enhanced dynamic range and fine-grained sensitivity unavailable in existing sensor technology. The sensor's dynamic range and sensitivity to low-frequency AC enable new capabilities in precision current control: a valuable and necessary capability in the control and management of circuit considerations, from applications for the grid to transportation, to the control of remote assets.

摘要： A metal casting is heated using infrared energy by introducing the metal casting into a heating system with infrared emitters directed towards the casting, and activating at least a portion of the emitters. The heating system includes a heating chamber, a plurality of directional infrared emitters in the heating chamber, an optical temperature sensor directed towards a part location in the interior of the heating chamber, and a thermal shield that is movable between a deployed position and a retracted position, the thermal shield comprising an observation duct. The observation duct provides a line-of-sight path between the optical temperature sensor and the part location when the thermal shield is in the deployed position, and the thermal shield is between the plurality of infrared emitters and the part location when the thermal shield is in the deployed position.

摘要： A glass laminate is produced using infrared emitters to deliver thermal energy to an unbonded glass laminate assembly. Heat may be conducted to the glass laminate by at least one ceramic glass substrate that absorbs at least a portion of the infrared radiation from the emitters, thereby bonding the glass laminate assembly more quickly and efficiently than a conventional vacuum bag process.
