    摘要： A two-channel fiber optic rotary joint of this invention can transmit simultaneously optic signals along two optic passes through a single mechanical rotational interface. The first channel of light path consists of a pair of fibers, co-axially fixed in 2 holders respectively. The light signal from one of the fiber can be directly coupled into another fiber. The second channel of light path is off-axis arranged, including a pair of conventional collimators, a pair of first reflecting surfaces and a pair of second reflecting surfaces. The light signal emitted from one of the said conventional collimator will be reflected by one of the said first reflecting surface, one of the said second reflecting surface, another said second reflecting surface, and another said first reflecting surface, then coupled into another said conventional collimator.

    摘要： A fiber optic polishing apparatus is disclosed including a single degree-of-freedom (DOF) gear transmission system, a pressurizing module, a fixture module, and a housing assembly motorized polisher. The single DOF gear transmission system would enable a fiber optic polishing machine, or polisher to be driven by only one motor, or by human hand. The manual polisher is a unique field polishing machine where electricity or battery is not available or not allowed. Both manual polisher and motorized polisher have the following features: polishing up to four connectors or ferrules simultaneously; adjustable force ensures consistent finish for a wide variety of connector types and the number of connectors in the fixture; quick release for convenient removal of polish fixture; low center of gravity for high stability; small footprint for multiple-machine operation to avoid time-consuming film change.

    摘要： In one embodiment, a method is provided for congestion mitigation. In this method, a congestion level of data flows along a path is monitored relative to a threshold. Here, each data flow is associated with a flow identifier. Based on detection that the congestion level exceeds the threshold, the flow identifier of a number (e.g., one or more) of the data flows is changed to a different flow identifier. This change results in the number of the data flows redirected to a different path. In an alternate embodiment, another method is provided for congestion avoidance. In this method, a data flow transmitted along a single path is received, and the data flow is split into multiple micro data flows. A different flow identifier is then assigned to each micro data flow. This change results in the multiple micro data flows distributed along multiple different paths.

    摘要： A fault protection and correction circuit for the control of a power converter is disclosed. An example circuit generates a waveform that drives a switch on or off and controls the power converter. The controller circuit in addition to power factor correction (PFC) circuitry includes a first and a second shut down mode modules, both of them cause the switching to stop. The circuit includes a module for receiving fault events. When a fault occurs, the controller enters the second shut down mode. The controller stays in the second shut down mode if the required current for this mode can be provided by the outside circuitry. Otherwise, the controller enters the first shut down mode that requires less current and subsequently restarts the controller. By modifying the outside circuitry the controller can respond differently to fault events.
