  • Powertrain system with wireless communication nodes and integrated RF shield guide layer
    Patent number: 12027676
    Abstract: An enclosed electrical device such as a battery pack for an electric powertrain system includes an enclosure having a tray and cover. The tray and cover together define an enclosure cavity. A radio frequency (RF) receiving node is located within the cavity. Printed circuit board assemblies (PCBAs) include an RF transmitting node. The PCBAs(s) are spaced apart from one another within the cavity. An RF shield guide layer is positioned between the PCBAs and the cover, such that the RF shield guide layer covers the PCBAs without covering the RF transmitting node. A battery pack and an electric powertrain system include the RF shield guide layer.

  • HLA-E BINDING
    Publication number: 20150361180
    Abstract: The invention relates to a method of testing a compound for biological activity, which method comprises providing cells expressing one of the CD94/NKG2 family of receptors, contacting the cells with recombinant HLA-E under binding conditions in the presence of the test compound, and determining whether the presence of the compound affects the binding of HLA-E to the cells. The HLA-E property of binding to CD94/NKG2 receptors on NK cells and a subset of CD8+ T cells is useful for targeting CD94/NKG2+ cells for a variety of purposes such as identification, isolation, killing or inactivation.
