  • Patent number: 8896251
    Abstract: This disclosure relates to diagnosing a power electronic device by itself and extending the diagnostics to an electric machine coupled with the power electronic device and deployed at an operational site. The power electronic device can power and control the electric machine. The diagnostics can include testing the status of the power electronic device, and monitoring hardware changes in the electric machine. The diagnostics can be performed within the power electronic device on demand, periodically, or both. In some instances, the self-diagnostics can evaluate whether components are defective or wired incorrectly, characterized by wrong inductance, and/or resistance, for example. In some implementations, the power electronic device includes a digital signal processing unit for the self-diagnostics and a data record system for recording and troubleshooting errors related to load performance and/or parameters.

  • Patent number: 7037657
    Abstract: The identification of mutations in NURR1 provides molecular tools for the development of diagnostic, prophylactic and therapeutic agents for Parkinson's Disease. In specific embodiments, two point mutations are identified in exon 1 of the NURR1 gene in 10/107 (9.3%) cases of familial Parkinson's disease (PD). The mutations reduce NURR1 gene expression (mRNA and protein levels) by 87–95% and decrease tyrosine hydroxylase (a rate-limited dopamine synthesis enzyme) gene expression in vitro. It is also demonstrated that in vivo NURR1 mRNA levels in the lymphocytes from the PD patients with the exon 1 mutation are reduced by 68–84%, and in over 50% sporadic PD patients the NURR1 mRNA levels in lymphocytes are significantly reduced. A homozygous polymorphism is identified in intron 6 of NURR1 that correlates with the presence of Parkinson's disease. A splicing variant in NURR1 exon 5 is identified.
