Patent CH-693664-A5 (CH)
Title: Method and apparatus for measurement of oto-acoustic emissions impeded by disturbance noises involve disturbance noises picked up by reference microphone, filtered by adaptive filter and subtracted from distorted measurement signal
Inventor: KOMPIS MARTIN
IPC: A61B5/12
Filed: 1999-12-08
Abstract: The method and apparatus for measurement of oto-acoustic emissions impeded by disturbance noises involve the disturbance noises picked up by a reference microphone (11), filtered by an adaptive filter (13), and finally subtracted (15) from the disturbed measurement signal (8).  Disturbance noises enter the reference microphone, but no oto-acoustic emissions. Through the subtraction, in the system part (10) a disturbance noise-reducing signal (16) is produced, which can be further processed for the measurement of oto-acoustic emissions. The coefficients of the adaptive filter are continuously derived from an adaptation algorithm (18).

Patent CH-690048-A5 (CH)
Inventor: KORSHUN YVAN
IPC: G06F21/35
Filed: 1995-11-28
Abstract: The access control has the access code recorded on a portable support which is placed near a detector.

Title: Article resisting adhesion of ice e.g. for ski surface mfr.
Inventor: LENDHARD MARTIN
IPC: A63C5/056
Filed: 1976-12-08
Abstract: An article having a surface to which ice formed in situ does not adhere, consists of a polymer which is water-soluble or which contains water-soluble cpd.
