Title:
DEVICE FOR DIAGNOSTICS OF CYCLE-ACTION MECHANISMS
Document Type and Number:
WIPO Patent Application WO/1994/000741
Kind Code:
A1
Abstract:
The device comprises, connected in series, a vibrator power supply (1), an amplifier (2), a vibroacoustic signal processing unit (3) and a recording unit (4). The vibroacoustic signal processing unit (3) comprises an analog-to-digital converter (5) connected to the output of the amplifier (2), a recirculator (6) and a digital-to-analog converter (7) connected to the recording unit (4). The recirculator (6) consists of, connected in series, a double-input summer (8), a digital multiplier (9) and a controllable delay line (10) whose input is connected to the output of the analog-to-digital converter (5); the output of the digital multiplier (9) is connected to the input of the digital-to-analog converter (7), whereas the controlling input of the delay line (10) is connected through a digital frequency multiplier (11) and a pulse generator (12), connected in series, to a cycle phase transducer (13).
