An elevator load bearing assembly (30) includes a jacket (34) having different portions comprising different polymer compositions. In a disclosed example, a plurality of tension members (32) are at least partially surrounded by a first portion (36) comprising a first polymer composition. A second portion (38) establishes at least one exterior surface (40) of the jacket (34) and comprises a second polymer composition. In one example, a surface-modifying agent is added to alter the composition of at least a portion of the jacket (34). In another example, co-extrusion techniques using different polymer compositions establish different portions of the jacket (34).

An exhaust system, and a catalyzed substrate for use in an exhaust system, is disclosed. The exhaust system comprises a lean NOx trap and the catalyzed substrate. The catalyzed substrate has a first zone, having a platinum group metal loaded on a support, and a second zone, having copper or iron loaded on a zeolite. The first zone or second zone additionally comprises a base metal oxide or a base metal loaded on an inorganic oxide. Also provided are methods for treating an exhaust gas from an internal combustion engine using the exhaust system. The exhaust system is capable of storing NH3 generated in rich purging, reacting the NH3 with slip NOx, controlling H2S released from NOx trap desulfation, and oxidizing slip hydrocarbons and carbon monoxide. When the catalyzed substrate is a filter substrate, it is also capable of removing soot from exhaust system.

In one embodiment, a system for providing fault-tolerant inertial measurement data includes a sensor for measuring an inertial parameter and a processor. The sensor has less accuracy than a typical inertial measurement unit (IMU). The processor detects whether a difference exists between a first data stream received from a first inertial measurement unit and a second data stream received from a second inertial measurement unit. Upon detecting a difference, the processor determines whether at least one of the first or second inertial measurement units has failed by comparing each of the first and second data streams to the inertial parameter.

The presently disclosed subject matter related to methods of converting lignocellulosic materials to alcohol that include increasing the fiber consistency of enzymatic hydrolysis mixtures. More particularly, the methods involve contacting lignocellulosic biomass with an enzyme composition for a period of time, and then thickening the mixture and further hydrolyzing the thickened mixture. The thickening can be performed by filtration, optionally reusing the filtrate and/or any enzymes contained therein during the lignocellulose conversion process to increase the efficiency of the process. Hydrolysis of the thickened mixture provides a fermentable sugar mixture having a higher concentration of sugar than fermentable sugar mixtures provided from less concentrated biomass/enzyme mixtures. Compositions comprising alcohol prepared according to the presently disclosed methods are also provided.
