  • Publication number: 20220297383
    Abstract: An additive manufacturing (AM) method includes using an AM tool to fabricate a plurality of workpiece products; measuring qualities of the first workpiece products respectively; performing a temperature measurement on each of the melt pools on the powder bed during a fabrication of each of the workpiece products; performing photography on each of the melt pools on the powder bed during the fabrication of each of the workpiece products; extracting a length and a width of each of the melt pools; performing a melt-pool feature processing operation; building a conjecture model by using a plurality of sets of first process data and the actual metrology values of the first workpiece products in accordance with a prediction algorithm; and predicting a virtual metrology value of the second workpiece product by using the conjecture model based on a set of second process data.

  • Patent number: 11383450
    Abstract: An additive manufacturing (AM) system, an AM method, and an AM feature extraction method are provided. The AM system includes an AM tool, a product metrology system, an in-situ metrology system, a virtual metrology (VM) system, a compensator, a track planner, a controller, a simulator and an augmented reality (AR) device. The simulator is used to find feasible parameter ranges, while the AR device is used to support operations and maintenance of the AM tool. The product metrology system, the in-situ metrology system and the VM system are integrated to estimate the variation of material on a powder bed of the AM tool. The compensator is used for compensating the process variation by adjusting process parameters. The product metrology system is used to measure the quality of products. The in-situ metrology system is used to collect features of melt pools on the powder bed.

  • Patent number: 5534413
    Abstract: The present invention relates to a novel mycoplasma isolated from the urine of patients with AIDS. The mycoplasma has unique morphological and pathobiological properties. The invention also relates to the antigens and antibodies of the novel mycoplasma, and methods of detection utilizing these antigens and antibodies. Antigenically and genetically, the mycoplasma is distinct from all other known mycoplasmas.

  • Patent number: 5532134
    Abstract: The present invention relates to a diagnostic assay utilizing the lipid associated membrane proteins of mycoplasmas to detect the presence of species-specific mycoplasma antibodies. The sensitive assay is useful for the detection and differentiation of mycoplasma antibodies specific for individual species in biological samples from humans and animals, and exhibits virtually no cross-reactivity between different mycoplasma species.

  • Patent number: 5242820
    Abstract: The invention relates to a novel pathogenic mycoplasma isolated from patients with Acquired Immune Deficiency Syndrome (AIDS) and its use in detecting antibodies in sera of AIDS patients, patients with AIDS-related complex (ARC) or patients dying of diseases and symptoms resembling AIDS diseases. The invention further relates to specific DNA sequences, antibodies against the pathogenic mycoplasma, and their use in detecting DNA or antigens of the pathogenic mycoplasma or other genetically and serologically closely related mycoplasmas in infected tissue of patients with AIDS or ARC or patients dying of symptoms resembling AIDS diseases. The invention still further relates to a variety of different forms of vaccine against mycoplasma infection in humans and/or animals.
