    • A personal training device is provided for a participant of pace-based physical training. The device includes an input for receiving an input signal indicative of a pace of the participant, and a comparator coupled to the input for comparing the pace of the participant to a predefined criteria. The personal training device further includes a training partner positioner for generating a position of a virtual training partner relative to the participant based on an output of the comparator, and a training partner audio source for providing audio representative of sounds from the virtual training partner. Still further, the personal training device includes a spatial audio processor for producing a multi-dimensional audio signal comprising the audio from the audio source, the multi-dimensional audio signal providing the audio at a spatial location represented by the position generated by the training partner positioner.

    • Disclosed herein is an apparatus and method for measuring bio-impedance attributable to joint movement. The bio-impedance measuring apparatus includes a constant current source, current stimulus electrodes, at least two voltage detection electrodes, a demodulator, a signal gain and offset controller and an isolated amplifier. The method of measuring bio-impedance attributable to joint movement, comprising the steps: generating a weak current by use of a constant current source; causing the weak current to flow from a point to another point; forming L voltage detecting electrode pairs from voltage detecting electodes positioned at m points on each of nnull1 lines that divide an interval between a first joint and a second joint, between which the weak current flows, into equal n parts (m and n are natural numbers), using combination (mC2nullL); detecting bio-impedance at certain periods from J (LnullK) voltage detecting electrode pairs that are obtained by subtracting K voltage detecting electrode pairs, each of which exists on a single dividing line, from the formed L voltage detecting electrode pairs; and selecting a pair of voltage detecting electrodes having a highest variation of bio-impedance.
