Abstract: A contactless credential reader which is arranged to be installed in a rearward portion of a passenger seat of a transportation vehicle, such as an aircraft, in which the reader is arranged to be capable of being installed as either a rear mount or as a front mount.

Abstract: The present invention relates to a water-based polymer composition, comprising: at least one polymer (P) comprising recurring units (R1), from 0 to at most 25% mol of said recurring units (R1) comprising a carboxylic acid group (in acid or salt form); at least one aromatic polyamic acid (A) comprising recurring units, more than 50% mol of said recurring units comprising at least one aromatic ring and at least one amic acid group and/or imide group [recurring units (R2)], more than 50% mol of recurring units (R2) comprising at least one amic acid group, part or all of the amic acid groups being neutralized by at least one basic compound (B); water; optionally, at least one organic solvent (S) of the aromatic polyamic acid (A), in an amount of less than 20% wt with respect to the weight of the aromatic polyamic acid. The polymer (P) is preferably a fluoropolymer; it can be either a partially fluorinated fluoropolymer, such as ECTFE, or a perfluorinated fluoropolymer such as TFE polymers.

Abstract: Molding resin formulations comprising polyimides and a fluropolymer lubricant such as PTFE intended for use in fabrication of molded goods for friction and wear applications exhibit improved wear characteristics and good surface lubricity when further compounded with high modulus, highly graphitic, pitch-based carbon fiber.
