Abstract: Existing currency validation (CVAL) devices, systems, and methods are too slow, costly, intrusive, and/or bulky to be routinely used in common transaction locations (e.g., at checkout, at an automatic teller machine, etc.). Presented herein are devices, systems, and methods to facilitate optical validation of documents, merchandise, or currency at common transaction locations and to do so in an obtrusive and convenient way. More specifically, the present invention embraces a validation device that may be used alone or integrated within a larger system (e.g., point of sale system, kiosk, etc.). The present invention also embraces methods for currency validation using the validation device, as well as methods for improving the quality and consistency of data captured by the validation device for validation.

Abstract: The invention relates to alkylborane complexes with aromatic amines of the formula: ##STR1## in which R.sup.1 and R.sup.2 are the same or different (1-4C)-alkyl radicals, or together with the adjacent nitrogen atom are morpholino, piperidino or pyrrolidino radicals; R.sup.3 and R.sup.4 are independently selected from hydrogen, (1-4C)-alkyl, (1-4C)-alkoxy, di-(1-4C)-alkylamino, morpholino, piperidino and pyrrolidino; thexyl stands for 1,1,2-trimethylpropyl; and n is the integer 1 when R.sup.3 and R.sup.4 are other than nitrogen containing radicals, or the integer 1 or 2 when one of R.sup.3 and R.sup.4 is a nitrogen containing radical, or the integer 1, 2 or 3 when both R.sup.3 and R.sup.4 are nitrogen containing radicals.The complexes are more stable than thexylborane tetrahydrofuran complex, but are sufficiently reactive to be valuable as hydroborating and reducing agents.
