This paper describes two feature selection algorithms applied to different speech segments which are used in an on-line, adaptive speaker verification system. The Information Theoretic approach is used to reduce the redundancies among the features that are originally present in the feature pool. Next, the Between-to-Within variance ratio (BW ratio) feature ordering algorithm is applied for obtaini...Show More
A novel micropower, two-channel telemetry system, which has been used to transmit the occurrence of the QRS complex of the heart waveform and temperature information, is described. The system employs pulsewidth-modulation (PWM) and pulse-position-modulation (PPM) methods plus a few unique circuits and system-design techniques so that it has the following desirable features. 1) The transmitting uni...Show More
