  • Patent number: 10986698
    Abstract: A method and apparatus for thermally processing material on a low-temperature substrate using pulsed light from a flash lamp is disclosed. Material is conveyed past the flash lamp. The pulses of light are formed by Pulse Width Modulation to tailor the shape of the pulses to generate a thermal gradient in the substrate that enables the material to be heated beyond the maximum working temperature of the substrate without damage. Its shaped pulse rate is synchronized to the conveyance speed of a conveyance system. By using the information from a feedback sensor, the thermal gradient is recalculated to alter the shape of the pulses in real time for optimizing subsequent curings in real time without powering down the curing apparatus. The combined pulse shaping and synchronization allow a temperature profile to be tailored in the sample that is uniformly cured in the conveyance direction.

  • Patent number: 10960484
    Abstract: The present disclosure is directed to a component of a welding device that is configured to produce a shielding gas having a developed flow profile, which provides for a shielding gas column having a laminar profile over a greater length than has been achieved through conventional means. The component utilizes one or more flow restrictors, which are configured to provide higher resistance to the flow of shielding gas at increasing distances from the center of a shielding gas flow channel. By providing increasing resistance toward the periphery of the channel, a developed shielding gas flow profile may be achieved over a relatively short flow length.

  • Patent number: 10953497
    Abstract: A method of laser welding a workpiece stack-up (10) of overlapping steel workpieces (12, 14) involves heat-treating a region (64) of the stack-up (10) followed by forming a laser weld joint (66) that is located at least partially within the heat-treated region (64). During heat-treating, one or more pre-welding laser beams (68) are sequentially directed at a top surface (20) of the workpiece stack-up (10) and advanced along a pre-welding beam travel pattern (70) so as to reduce an amount of vaporizable zinc within the stack-up (10). Thereafter, the laser weld joint (66) is formed by directing a welding laser beam (82) at the top surface (20) of the workpiece stack-up (10) and advancing the welding laser beam (82) along a welding beam travel pattern (84) that at least partially overlaps with a coverage area of a pre-welding beam travel pattern (70) or a shared coverage area portion of multiple pre-welding beam travel patterns (70).

  • Patent number: 10952289
    Abstract: A defrosting system includes an RF signal source, one or more electrodes proximate to a cavity within which a load to be defrosted is positioned, a transmission path between the RF signal source and the electrode(s), and an impedance matching network electrically coupled along the transmission path between the RF signal source output and the electrode(s). A system controller is configured to modify, based on the reflected signal power, values of variable passive components of the impedance matching network to reduce the reflected signal power. The system controller may be configured to estimate the mass of the load by comparing component value(s) of one or more variable passive components of the impedance matching network with a component value table stored in memory, where stored mass values correspond to the stored component values. Desired signal parameters for the RF signal may be determined based on the estimated mass of the load.

  • Patent number: 10926346
    Abstract: A power delivery system includes a power-input-channel, an AC/DC converter, one or more controller-circuits, a silicon-controlled-rectifier, a transformer, and a pair of output-leads. The power-input-channel receives alternating-current from a power-source. The AC/DC converter converts the alternating-current to a direct-current at a converter-output. The one or more controller-circuits are connected with the converter-output and control a signal indicative of a desired-power-level delivered for a desired-time. The silicon-controlled-rectifier is connected with the power-input-channel and controls an SCR-output-voltage to an SCR-output-channel proportional to the signal. The transformer reduces the SCR-output-voltage from a primary-side to a secondary-voltage on a secondary-side. The pair of output-leads are connected with poles of the secondary-side. A solder-joint is disposed between the pair of output-leads.
