摘要： A signal transmission system for transmitting a main process variable and further data between a field device and a superordinate unit, includes a first conversion arrangement, a second conversion arrangement and an optocoupler arrangement. The optocoupler arrangement is connected between the first conversion arrangement and the second conversion arrangement. The first conversion arrangement is configured to convert at least the further data exchanged between the field device and the superordinate unit into a data signal transmittable via the optocoupler arrangement. The optocoupler arrangement transmits the data signal between the first conversion arrangement and the second conversion arrangement. The second conversion arrangement converts the data signal to the further data and transmits it to the field device. A method transmits a main process variable and further data between a field device and a superordinate unit. In the method, at least the further data is transmitted via an optocoupler arrangement.

摘要： A wireless sensor network gateway includes safe side circuitry, hazardous side circuitry and isolation circuitry, which are supported by a housing. The safe side circuitry includes a safe side power circuit, and a safe side data input/output (I/O) circuit. The hazardous side circuitry includes a hazardous side power circuit, and a hazardous side data I/O circuit. The isolation circuitry divides the safe side circuitry from the hazardous side circuitry. The isolation circuitry includes a power isolation circuit that couples the safe side power circuit to the hazardous side power circuit and forms an intrinsic safety barrier between the safe side power circuit and the hazardous side power circuit, and a data isolation circuit that couples the safe side data I/O circuit to the hazardous side data I/O circuit and forms an intrinsic safety barrier between the safe side data I/O circuit and the hazardous side data I/O circuit.

摘要： An apparatus includes a polarization beam splitter (PBS) and an optical detector. The PBS is configured to receive a polarized optical signal transported via an optical communication path of an optical network. The detector is configured to receive from the PBS a first polarization component of the optical signal, and to produce a first electrical measure of the first polarization component. A processor is configured to determine a dynamic metric of the optical communication path based at least on the first electrical measure. Some embodiments also include a second detector configured to receive from the PBS a second polarization component of the optical signal. The second detector produces a second electrical measure of the second polarization component, and the processor is configured to determine the dynamic metric based on both the first and second electrical measures.

摘要： An apparatus includes a first terminal, a second terminal, a bi-directional regulator circuit, and functional circuitry. The bi-directional regulator circuit generates a voltage across a first power supply node and a second power supply node in response to an input current flowing through the first terminal and the second terminal with a first polarity. The bi-directional regulator circuit also generates the voltage across the first power supply node and the second power supply node in response to the input current flowing through the first terminal and the second terminal with a second polarity opposite the first polarity. The functional circuitry is powered by the voltage and is configured to generate a signal using the voltage. The signal is indicative of the input current in response to the input current being supplied to the first terminal and is indicative of the input current in response to presence of the input current.

摘要： A quasi-optical coupling system launches and extracts surface wave communication transmissions from a wire. At millimeter-wave frequencies, where the wavelength is small compared to the macroscopic size of the equipment, the millimeter-wave transmissions can be transported from one place to another and diverted via lenses and reflectors, much like visible light. Transmitters and receivers can be positioned near telephone and power lines and reflectors placed on or near the cables can reflect transmissions onto or off of the cables. The lenses on the transmitters are focused, and the reflectors positioned such that the reflected transmissions are guided waves on the surface of the cables. The reflectors can be polarization sensitive, where one or more of a set of guided wave modes can be reflected off the wire based on the polarization of the guided wave modes and polarization and orientation of the reflector.

摘要： A system and method are disclosed for providing electrically isolated communications between two USB2 devices. Two isolating eUSB2 repeaters are utilized to implement a digital isolation barrier between the two USB2 devices. The isolating eUSB2 repeaters are configured to broker isolated communications between the two USB2 devices using a modified eUSB2 protocol that allows the two isolating eUSB2 repeaters to interoperate across the isolating barrier. The modified eUSB2 protocol allows the two isolating eUSB2 repeaters to broker isolating communications on behalf of the USB2 devices without the use of an accurate clock signal. The modified eUSB2 protocol utilized by the isolating eUSB2 repeaters is configured in particular to support certain end-of-packet translations between USB2 data and the modified eUSB2 protocol, management of certain USB2 bus state transitions and assignment of roles to the two isolating eUSB2 repeaters.
