Abstract: Embodiments are directed to compositions comprising at least one polyethylene (PE) having a density ranging from 0.850 g/cc to 0.970 g/cc, and a polymer processing aid (PPA) masterbatch comprising a PPA polymer blend, at least one polymeric carrier, and optionally up to 12 wt. % of one or more inorganic materials. The PPA polymer blend comprises from 40 to 60 wt. % of one or more fluoroelastomers, and from 40 to 60 wt. % of polyethylene glycol. The composition further comprises at least one fragrance oil. The composition is defined by the equation: RED (PE?PPA masterbatch)<RED (Fragrance oil?PPA masterbatch), wherein the RED (PE?PPA masterbatch) is the relative energy difference (RED) value for the PE and PPA masterbatch and RED (Fragrance oil?PPA masterbatch) is the RED value for the fragrance oil and PPA masterbatch.

Abstract: Methods and apparatus for utilizing vehicle wheel assembly surface profile data acquired by a vehicle wheel service system from a non-contact imaging sensor and a projected pattern of optically distinct elements on the vehicle wheel assembly surface to identify one or more features of the vehicle wheel assembly, to receive operator input, and to facilitate the placement of imbalance correction weights onto the vehicle wheel assembly surface.

Abstract: A vehicle wheel service system configured with a load roller assembly to apply a generally radial load to a vehicle wheel assembly during rotation, and which is configured with sensors to obtain one or more measurements of lateral forces associated with the vehicle wheel assembly during the loaded rotation, from which a quantified representation of lateral force for the tire of the vehicle wheel assembly is determined.

Abstract: A vehicle service or inspection system including a load roller for applying a radial load to a vehicle wheel assembly consisting of a tire mounted to a rim, with at least one sensor for acquiring measurements of acoustical energy generated by the wheel assembly during loaded rotational movement. The vehicle service or inspection system is configured with a programmed processor to evaluate the acquired measurements to provide a measure of tire road noise, identification of tire defects, and/or identification of sources of noise, vibrations, or acoustical energy on the tire surface such as tire flat spots, cupping, bubbles, embedded foreign objects, or other defects. The processor is further configured with software instructions to utilize the acquired measurements to provide a consumer with a figure of merit associated with the acoustics of the tire undergoing testing.

Abstract: A machine vision vehicle wheel alignment system optical target assembly which incorporates an adaptor for attachment of an optical target to a vehicle wheel assembly. The adaptor includes a circular sinusoidal edge for seating in a non-determined position against surfaces of a vehicle wheel assembly, and a pair of pivoting arm assemblies capable of independent movement which are configured to position tire hooks for gripping the tread surfaces of a tire mounted to the wheel rim. Forces exerted between the pivoting arms are transferred to the tire hooks to hold the optical target assembly in contact with the wheel assembly surface. The optical target is integrated into the adaptor, and maintained in a stationary relationship to the wheel assembly thereby during a vehicle wheel alignment procedure.

Abstract: A machine vision vehicle wheel alignment system optical target assembly incorporating an adaptor for attachment of an optical target to a vehicle wheel assembly. The adaptor includes at least three contact points for abutment against surfaces of a vehicle wheel assembly, and an attachment mechanism configured to grip surfaces of a tire mounted to the wheel rim to hold the optical target assembly in contact with the wheel assembly surface. The optical target is secured to the adaptor, and maintained in a fixed relationship to the wheel assembly thereby during a vehicle wheel alignment measurement procedure.

Abstract: A method and apparatus for its practice are provided of differentiating at least one component of a heterogeneous sample from other component(s) using harmonic resonance imaging and of obtaining information regarding the sample from the differentiation. In a preferred embodiment, an image is created of a property of a harmonic or a combination of a harmonics producing a response having a contrast factor between the sample's constituent components. The desired harmonic(s) can be identified either in a preliminary data acquisition procedure on the sample or, if the sample's constituent components are known in advance, predetermined. The desired harnonic(s) may be identified directly by the user or automatically through, e.g., pattern recognition. A compositional map may then be generated and displayed and/or additional information about the sample may be obtained.
