Abstract: An electronic apparatus for reducing interference in a desired signal, the apparatus comprising: (a) a plurality of measurement signal lines, each connected to a respective measurement signal electrode; and (b) one or more reference signal lines, each connected to respective one or more reference electrodes; each of said measurement signal lines or a respective group of said measurement signal lines being associated by being in close physical proximity with a respective one of said reference signal lines for a substantial part of their lengths, so that each measurement signal line or signal line group with its corresponding reference signal line forms a measurement signal line or measurement signal line group/reference signal line pair, said electronic apparatus further comprising subtraction means for subtracting an interference on each reference signal line from an interference signal on the associated measurement signal line or from each measurement signal line in the measurement signal line group in that

Abstract: 1,2,3-triazoles and 1,2,4-triazoles having an N-substituted acylamino substituent are prepared by alkylating N-unsubstituted acylamino triazoles or acylating N-substituted amino triazoles. The N-substituted acylamino triazoles are useful as anti-allergy drugs. Pharmaceutical formulations containing acylamino triazoles and a method of treating allergic conditions utilizing such compounds are provided.

Abstract: Acylamino heteroaryl compounds in which the heteroaryl nucleus is a 5-membered ring containing a single heteroatom, which may be oxygen, or sulphur, methods of making the compounds and pharmaceutical formulations containing the compounds. The compounds have anti-allergy activity.
