    摘要： A magnetic coupling is provided having a first shaft and a second shaft. A plurality of first magnets is in rotationally driving engagement with the first shaft and defines alternating polarity magnetic surfaces. A plurality of second magnets is in rotationally driving engagement with the second shaft and defines alternating polarity magnetic surfaces. The first and second magnet surfaces are separated by a gap so that rotation of one of the first magnets and second magnets urges synchronous rotation of the other. An electrically conductive member is in rotationally driving engagement with the second shaft and is disposed proximate to the first magnet surfaces so that rotation of the conductive member or the first magnets relative to the other induces electric current in the conductive member and urges asynchronous rotation of the other of the conductive member and the first magnets in the same rotational direction.

    摘要： According to one embodiment, the present invention provides a rotor assembly. The exemplary rotor assembly includes a plurality of rotor laminations, which cooperate to form a rotor core, capped at each end by end members. Extending through the rotor core and the end members, a plurality of rotor channels is configured to receive electrically conductive members therethrough. Each of the electrically conductive members has external portions, which extend beyond the rotor channel, and an interior portion that is housed within the rotor channel. By flexing the external portions, a compression force that secures the laminations and the end members with respect to one another may be provided. Advantageously, the external portions may be fused to one another and/or to the end members. As one example, the external portions may be fused through the introduction of a molten metal into the end member. Advantageously, fusing of the external portions to the end members and/or one another increases the mechanical integrity of the rotor and provides for good electrical communicativeness between the conductive members, for example.

    摘要： A laser communication system for full duplex wideband data transmission includes first and second terminals having dichroic wavelength-multiplexed optical systems wherein transmitted and received light are multiplexed along a path through the same aperture. The optical systems each preferably comprise a cassegrain receiver having primary and secondary mirrors for directing both transmitted and received laser light. Modulated laser light is generated by a high-power laser diode which is actively cooled by a thermoelectric cooler. A window in the housing, through which the modulated laser light travels, includes a transparent resistive coating to which electrical current is applied to control the temperature of the window. The aspheric primary mirror has a highly reflective surface, preferably a single-point diamond-turned mirror surface, formed on an aluminum substrate as a single piece.
