    • A wireless atmospheric site-to-site full-duplex (i.e., simultaneous transmit and receive) laser communication system, typically for wideband (high-speed) data, voice, and/or video transmission. The system includes at least one laser communication transceiver each having an electro-optical transmitter that includes a laser source for generating laser light to be transmitted site-to-site and at high speed, an electro-optical receiver that includes a baffle assembly for receiving light directly onto a detector, without an intermediate field stop and re-imaging relay optics to reject off-axis light sources. Wideband data are transmitted and received through the atmosphere by the electro-optical transmitter and the electro-optical receiver. The data to be transmitted through each laser communication transceiver is inputted through a fiber-optic receiver and outputted by a fiber-optic transmitter. Outgoing laser light is generated by the laser source after it is triggered by an inputted signal from the fiber-optic receiver.

    • 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.

    • 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.

    • A hot-plugging circuit associated with a backplane or motherboard for controlling the rate of application of voltage and current to a non-operating printed-circuit card in the process of being inserted into a backplane connector in a system including other already-operating printed-circuit cards. Each backplane connector has connector contacts of two different lengths. An isolation diode at each connector is connected to two of the longer contacts of the connector and is forward biased by a non-operating printed-circuit card being inserted into that connector. The forward-biased isolation diode triggers a card insertion circuit to recognize that a non-operating printed-circuit card is in the process of being inserted. The card insertion circuit triggers a voltage and current control circuit to ramp up the voltage and current furnished to the non-operating printed circuit. The card insertion circuit also triggers a timeout circuit which, in the case of a printed-circuit card which draws a high current, terminates the operation of the control circuit after a time period during which the printed-circuit board should normally have been inserted, if the card is angled too much upon insertion and can not be fully inserted. Completion of insertion of the printed-circuit card makes electrical connection to shorter contacts which carry the normal voltage supply to the printed-circuit card and disables the control circuit.
