    摘要: Disclosed are exemplary embodiments of thermally-conductive electromagnetic interference (EMI) absorbers. In exemplary embodiments, the thermally-conductive EMI absorber may have a thermal conductivity of at least 5 Watts per meter per Kelvin (W/mK). The thermally-conductive EMI absorber may have an attenuation greater than 15 decibels per centimeter (dB/cm) at a frequency of 10 gigahertz (GHz) or higher. Or the thermally-conductive EMI absorber may have an attenuation within a range from about 1 dB/cm to about 15 dB/cm for frequencies within a range from 1 MHz to 2 GHz.

    摘要: The present disclosure relates to the use of silicone carbinols as components in composites, such as polymer-inorganic composites useful for the management of heat and/or electromagnetic interference (EMI) and other polymer-inorganic composites used for other purposes. In exemplary embodiments, silicone carbinol is added to a composite in an amount sufficient for increasing flow rate of the composite. The increased flow rate of the composite enables a useful increase in functional filler content, which, in turn, allows increased benefits related to performance. For example, functional filler loadings/particle concentrations may be increased in a thermal and/or EMI management material for higher thermal and/or electrical conductivity as the silicone carbinol helps to retain a desired dispensing flow rate for the composite despite the higher functional filler loadings/particle concentrations in the composite.

    摘要: FIG. 1 is a perspective view of a material having edge shape showing our new design;
    FIG. 2 is a cross-sectional perspective view of the material having edge shape of FIG. 1, taken along lines 2-2 in FIG. 1;
    FIG. 3 is a front elevation view of the material having edge shape of FIG. 1;
    FIG. 4 is a rear elevation view of the material having edge shape of FIG. 1;
    FIG. 5 is a top plan view of the material having edge shape of FIG. 1;
    FIG. 6 is a right side elevation view of the material having edge shape of FIG. 1; and,
    FIG. 7 is a left side elevation view of the material having edge shape of FIG. 1.
    The evenly spaced broken lines in FIGS. 1 through 7 represent portions of the material having edge shape and form no part of the claimed design. The material having edge shape is shown with a symbolic break in its length and width. The appearance of any portion of the material having edge shape between the break lines forms no part of the claimed design.

    摘要: A control unit for controlling a rolling stock includes a user interface. The control unit is configured to receive, via the user interface, a plurality of user inputs corresponding to a plurality of users servicing the rolling stock, determine whether at least one user of the plurality of users remains servicing the rolling stock, and if at least one user of the one or more users remains servicing the rolling stock, prevent unauthorized movement of the rolling stock. Other example control units, computer systems including one or more control units, and computer-implemented methods for preventing unauthorized movement of a rolling stock are also disclosed.
