Naslov: ENERGY-EFFICIENT SYSTEM FOR DISTANT MEASUREMENT OF ANALOGUE SIGNALS
Hrvatski patentni glasnik: (2014)
Broj patenta: WO/2014/195744
Datum patenta: 11.12.2014
MKP klasifikacija: H03M 1/12
Naziv druge klasifikacije: (2006.01)

Ključne riječi: Analog signals; measurement unit; wireless transmission; UWB
Sažetak:
The invention discloses an energy-efficient system for, preferably wireless, measurement of analogue signals comprising one or more measuring units (10). Each measuring unit (10) comprises measuring probe (11)' which signal is processed by the modulator (12). All measuring units (10) have identical modulators (12) selected from the Time Encoding Machine (TEM) family consisting of: Asynchronous Sigma Delta Modulator (ASDM), Integrate And Fire Modulator (IAFM) and Integral Pulse Frequency Modulator (IPFM). Signal from modulator (12) is processed by a delay circuit (13) from which is optionally fed back to the modulator (12). Signal from the delay circuit (13) and modulator (12) is used to trigger UWB pulse generator (14), from where is optionally amplified via amplifier (15) and transmitted via transmission line or antenna (16). The delay circuit (13) uniquely characterizes measuring unit (10) and enables receiving unit (20) to separate received signals from plurality of measuring units (10) signals sent in unsynchronized manner. The invention is useful for long term acquisition of analog signals, especially time varying signals such as biological signals, i.e. ECG or EEG.
