Abstract: The invention provides a PVB interlayer sheet having a surface topography on at least one surface which is characterized as having a relatively low profile and a controlled, collapsible surface roughness profile (upon exposure to heat) having a population of significantly more surface peaks than negative peaks (valleys) in certain embodiments and slightly more distant peak spacing than is generally found in embossed PVB interlayers. The PVB interlayer sheets of the invention thus provide very good initial contact and tack of PVB to a glass surface, while leaving very little residual air behind after a first nip in a traditional glass lamination process when compared to other surface designs. The PVB interlayer sheets of the invention also exhibit a wide deairing window which affords greater tolerance of temperature and process variations.

Abstract: A system for measuring motion of a locomotive vehicle includes a speed sensor, a decelerometer and an onboard processing unit. The speed sensor is configured to measure wheel speed of the locomotive vehicle. The decelerometer includes a level-sensitive device configured to measure acceleration or deceleration of the locomotive vehicle as a function of a tilt from a level position. The onboard processing unit computes a current grade traversed by the locomotive vehicle prior to detection of a slip or slide condition based on a first measurement signal from the decelerometer. Upon detection of the slip or slide condition, the onboard processing unit obtains a second measurement signal from the decelerometer and filters out the current grade from the second measurement signal. The onboard processing unit determines an actual acceleration or deceleration of the locomotive vehicle during the slip or slide condition from the filtered second measurement signal from the decelerometer.
