摘要： A footrest is mounted to the frame of a forward seat and is pivotally mounted thereto to be movable between a raised stored position adjacent the back of the seat to a lowered use position for supporting a second row passenger's feet. The footrest responds to a force above a predetermined level to breakaway to prevent damage to the footrest which can be subsequently returned to the use or stored position. In a preferred embodiment of the invention, the footrest comprises a generally U-shaped member having a mounting bracket including the pivot coupling to opposite ends of the member to allow such pivotal movement. In addition, the mounting bracket and U-shaped footrest include a deformable stop extending between the two which holds the footrest in a use position and allows the footrest to pivot downwardly if an excessive force is placed thereon.

摘要： The present disclosure generally pertains to systems and methods for swapping span power modules that are used for supplying power to network interface units (NIUs). A span power module in accordance with one exemplary embodiment of the present disclosure has logic capable of communicating with logic of another span power module. When one module is to be swapped for the other module, the module being swapped-in is configured to automatically disable the other module shortly after it has powered up and is supplying electrical power across a span line. The amount of time that both modules supply power to the span line is sufficiently small such that damage to electrical communication equipment receiving power from the span line is prevented.

摘要： An interworking function (IWF) at an edge of a packet network comprises a primary receiver and a backup receiver. The primary receiver receives data packets and timing information from a packet network. The primary receiver interworks data from the data packets into a data signal that is based on a local clock signal. The primary receiver uses the timing information from the packet network to adjust the frequency of the local clock signal such that it is synchronous to a network clock signal, such as a clock signal at an IWF, referred to as the “transmitting IWF,” that transmitted the data packets. In addition, the primary receiver from time-to-time provides timing information, such as a frequency control word, to the backup receiver, which uses such timing information to synchronize a clock signal of the backup receiver to the network clock signal upon an occurrence of a switchover from the primary receiver to the backup receiver. By using the timing information from the primary transceiver, the backup transceiver is able to synchronize its clock signal to the network clock signal in less time.
