摘要： Torsional oscillation of a shaft in a swing drive system of an excavator is minimized by monitoring torsional strain of the shaft. An electric motor provides torque to the shaft in response to a drive signal provided by a converter. A compensation circuit produces a compensation signal as a function of torsional strain of the shaft. A field excitation circuit or regulator powers a converter as a function of the compensation signal such that a counter torque is provided to the shaft and torsional oscillation of the shaft is reduced.

摘要： A fiber optic distribution cable having at least one mid-span access location includes a plurality of optical connection nodes for providing access to preterminated optical fibers of the distribution cable. Preferably, the optical connection nodes are articulated and linked together to form a low-profile linear chain of connection nodes that is sufficiently flexible to be deployed through small diameter conduit and aerial lashing equipment. Each connection node includes a housing that surrounds the distribution cable, a connecting link for receiving and routing one or more of the preterminated optical fibers, and an adapter for interconnecting a preterminated and connectorized optical fiber of the distribution cable with a connectorized optical fiber of a branch cable or drop cable. The distribution cable may also include a tether attached to the distribution cable such that the linear chain of connection nodes is slidably or removably attached to the distribution cable.

摘要： A fiber optic distribution cable assembly having at least one factory-prepared mid-span access location for accessing and terminating optical fibers of the distribution cable includes a tether containing at least one optical fiber optically connected to an optical fiber terminated from the distribution cable and an overmolded body encapsulating the distribution cable and a portion of the tether to form the mid-span access location. The mid-span access location is provided with a preferential bend along an axis that is common to the distribution cable and the tether by a strength member positioned within the overmolded body and/or the overmolded body having a geometrical configuration that promotes bending along the common axis. The preferential bend reduces any path length differences between terminated optical fibers routed substantially on the common axis and optical fibers remaining within the distribution cable induced by bending, thereby preventing breakage of the terminated optical fibers.

摘要： A fiber optic distribution cable assembly includes a distribution cable having at least one predetermined mid-span access location and a tether for mitigating cable length errors at the mid-span access location in a pre-engineered fiber optic communications network. At least one optical fiber of the distribution cable is accessed at the mid-span access location and optically connected to an optical fiber disposed within the tether. Preferably, the first end of the tether is attached to the distribution cable by overmolding the mid-span access location with a flexible encapsulant material. The end of the optical fiber of the tether may be splice-ready or connectorized at the second end of the tether and protected within a crush resistant tube. Alternatively, the second end of the tether may terminate in an optical connection terminal defining at least one optical connection node, or may terminate in a linear chain of articulated optical connection nodes.
