    摘要： A radio-over-fiber (RoF) hybrid wired/wireless transponder is disclosed that is configured to provide both wireless and wired communication between a hybrid head-end and one or more client devices. The hybrid transponder includes optical-to-electrical (O/E) and electrical-to-optical (E/O) conversion capability and is configured to frequency multiplex/demultiplex electrical “wired” signals and electrical “wireless” signals. The electrical wireless signals are wirelessly communicated to the client device(s) via a multiple-input/multiple-output (MIMO) antenna system within a cellular coverage area. The electrical wired signals are communicated to the client device(s) via a wireline cable that plugs into a wireline cable port on the transponder. The hybrid RoF system includes a hybrid head-end capable of transmitting and receiving wired and wireless optical signals, and an optical fiber cable that is optically coupled to the hybrid head-end and to at least one hybrid transponder. Drop-down transponder configurations that allow for easy wired and wireless connectivity between the client device(s) to the transponder(s) are also disclosed.

    摘要： Methods and apparatus for drying ceramic green bodies include providing one or more ceramic green bodies in a microwave heating chamber operatively connected to a microwave source and a PLC. The total mass of the ceramic green bodies present in the microwave heating chamber is determined. Microwave energy is generated with the microwave source and transmitted from the microwave source to the microwave heating chamber. A transmitted power of the microwave energy transmitted from the microwave source to the microwave heating chamber is measured with power sensors. The reflected power of reflected microwave energy reflected back from the microwave heating chamber is also measured. The power of the microwave energy transmitted from the microwave source to the microwave heating chamber is adjusted based on the total mass of ceramic green bodies present in the microwave heating chamber, the measured transmitted power and the measured reflected power.

    摘要： An optically-switched fiber optic communication system, such as a Radio-over-Fiber (RoF) based optical fiber link system, may be used to increase the range of peer-to-peer communications. The optically-switched fiber optic communication system may include a head-end unit (HEU) having an optical switch bank. Fiber optic cables comprising optical fibers optically couple the HEU to one or more remote access points in different coverage areas. The optical switch bank in the HEU provides a link between the remote access points in the different coverage areas such that devices in the different cellular coverage areas can communicate with each other over the optical fibers through the HEU. By using the optically-switched fiber optic communication system, the range and coverage of communication between devices may be extended such that devices in different coverage areas and devices using different communication protocols can communicate.

    摘要： Fiber optic array cables and related systems and methods to determine and/or track locations of objects are disclosed. The fiber optic array cables can be employed in an optical-fiber-based communication system, including a centralized optical-fiber based communication system. In one embodiment, the fiber optic array cable is configured to carry optical RF or radio-over-fiber (RoF) signals to establish communications with objects. The fiber optic array cable includes multiple reference units along the length of the cable. The reference units can be configured to convert received optical RF signals into electrical RF signals to establish RF communications with objects capable of receiving electrical RF signals. The reference units are also configured to convert received electrical RF signals from the objects into optical RF signals, which are then used to determine the location of the object. Having the availability of the multiple reference units on one or more the fiber optic array cables can provide enhanced reliability in tracking objects.

    摘要： Methods for determining when to regenerate an exhaust gas particulate filter (10), for regenerating, and for calibrating a pressure drop across such filters are disclosed. An example method involves reducing a first amount of particulates (52) accumulated in the filter to a residual amount RADP. The method also includes measuring the residual amount RADP by exciting the microwave resonant cavity (126) in which the filter resides with microwave radiation (182) and then monitoring the microwave cavity response. The method also includes using the measured value of RADP to calibrate a pressure drop threshold ΔPTH SO that it is representative of a limit (TDP) of particulate accumulation in the filter. The methods may also include regenerating the filter a number of times and each time re-setting the pressure drop threshold ΔPTH based on measurements of RADP taken after each filter regeneration.
