    摘要: A molded case circuit breaker having current limiting capabilities is dimensionally optimized for relatively smaller frame size circuit breakers. The handle yoke is supported with rollers thereby allowing the crossbar to be disposed in the space normally utilized for the handle yoke pivot axis. A clinch joint arcer assembly with a plurality of arcing contact arms, each pivotally connected by a clinch joint to a pivotally mounted main contact arm permits additional main contact arms to be provided in the same space normally occupied by the arcing contact arms alone. Additionally, arcing contact spring housings protect the arcing contact springs from deterioration due to corrosive ionizing gases generated during interruption. A positive off link assembly prevents the operating handle from being placed on an OFF position when the main contacts are welded together and transfers the force applied to the operating handle to the upper link to allow the weld to be broken. Lastly, a reversible barrier in one of the sidewalls allows in one position circuit breaker auxiliaries, located in the outside pole compartments, to communicate with the operating mechanism and the operating handle. For circuit breakers without auxiliaries, the barrier acts as an interphase gas barrier.

    摘要: A molded case circuit breaker is provided. Key blocks with a key shaped projection along one side are received in key shaped grooves in the sidewalls of the base. The kay shaped projections and the key shaped grooves may be formed as a dovetail connection. These key blocks provide support for the sidewalls from forces resulting from relatively high overcurrent conditions, such as a short circuit condition. In addition to supporting the sidewalls, the key blocks also form a barrier between the main contacts and other components in the circuit breaker to reduce the amount of arc products allowed to interact with the other components in the circuit breaker. The key block also form a stop surface for capturing the arc chutes to prevent movement of the arc chutes along the longitudinal axis of the circuit breaker. Lastly, the key blocks also hold the insulation barrier on the line conductor in place, thus obviating the need to use adhesives.

    摘要: An improved network interface architecture for a packet switch provides a mechanism for handling voice and data packets. Bandwidth allocation can be changed because control and data memories are synchronized to one another. A hierarchical addressing technique is employed to enhance flexibility in handling packet information. This method permits packet message data and certain packet control data to be stored in memory locations without having to be duplicated at a different memory location prior to transmission of the packet. In an exemplary wireless TDMA packet network a control module (CM) sends a time stamp relative to the beginning of its frame in a synchronization packet allowing each of a plurality of user modules (UM) to maintain synchronization relative to the CM. The CM uses a plurality of directional antennas and transmits the synchronization packets over each antenna over a predetermined number of frames. The UMs use a receive time stamp to identify the beginning of a received synchronization packet. The difference between the time stamps combined with a delay constant is used by the UMs to adjust time synchronization to the CM frame. Packets are communicated between the controller and the peripherals at the UM and CM over a bus using a communication protocol which increases the efficiencies of packet communications by allowing additional direct command lines between the communications controller and peripherals.

    摘要: A packet switching system (100) having a packet switch (140) employs an acknowledgement scheme in order assure the delivery of all fragments (310) comprising a fragmented data packet (300) to improve overall system throughput during the handling of packets (310) that require reassembly. When packet fragments (310) are lost, corrupted or otherwise unintelligible to a receiving device (92, 94), the acknowledgement scheme permits retransmission of the missing data. In addition, a second acknowledgment signal is scheduled by system processing resources (110) in order to verify the successful delivery of all retransmitted data.

    摘要: Multiple interrupt request data is stored in a queue and handled by a single interrupt sub-routine to provide a batch handling capability to maximize the interrupt handling efficiency of a microprocessor. Events are organized into groups having a common interrupt handling requirement and a data storage queue is provided for each group. At least one data word is stored for each event requiring interrupt attention in a respective queue. An interrupt handling routine upon a single call handles all data words within a queue before exiting the interrupt handling routine.

    摘要: A molded case circuit breaker is provided with a two piece cradle assembly having a cradle portion and a heat-treated portion. The heat-treated portion forms the latch and reset surfaces. The cradle portion is integrally formed from a pair of spaced apart cradle-shaped arms joined together by a connecting portion. The heat treated portion is securely fastened to the connecting portion to form the two piece cradle assembly. A hold down slidably carries a handle barrier with respect to the cover and closes a centrally located aperture in the cover for all handle positions. The handle barrier prevents arc products resulting from a separation of the main contacts from escaping through the centrally located aperture in the cover. Stops are provided in one or both directions to prevent misalignment of the handle barrier with respect to the operating handle. A cover interlock is also provided to prevent the cover from being removed when the circuit breaker is in an "on" position. The cover interlock can either be molded separately or integrallly molded with the handle barrier hold down.

    摘要: A method, device and system for providing communication session mobility of multimedia content delivered to a mobile communication device, such as a Digital Video Broadcasting-Handheld (DVB-H) mobile video device. For example, multimedia content delivered to a mobile communication device via a DVB-H network can be transferred seamlessly to a cellular data network. Session mobility is provided using a control server or session controller configured to manage and facilitate the transfer of the content delivery. The control server manages the transfer in response to receiving appropriate communication session control information from the mobile communication device. The control server can be a network element coupled to or contained within the network that couples a multimedia content source to one or more wireless control points that communicate with the end user mobile communication device. Alternatively, the control server can be partially or completely included or contained within the multimedia content provider.

    摘要: An apparatus for operating a clutch in a split-axle mechanism of a vehicle for instantaneously engaging four-wheel drive. In a preferred embodiment the apparatus includes a cable operatively connected to a control switch within the passenger compartment of the vehicle and an actuator, adjacent to the split axle mechanism. Activation of the switch causes instantaneous movement of the cable which, in turn, instantaneously causes the actuator to engage or disengage the clutch. When the clutch is engaged, the split axles rotate together. When the clutch is disengaged, the split axles rotate independently. In another embodiment a locking device is used to lock the actuator in position. The actuator can be locked to engage or disengage the clutch for enabling or disabling four-wheel drive.
