In this paper the implementation of a multi-carrier ADSL digital communication system in a TMS320C6748 DSP Development kit (LCDK) digital signal processor (DSP) is presented. QAM modulation / demodulation schemes, symbol timing and an equalization scheme are implemented. The information sent through the system is processed using cyclic redundancy check blocks, Scrambler and Reed-Solomon encoding. The operation of the system is verified experimentally by designating eight low frequency carriers and using the audio CODEC available in the DSP kit.

This work presents the initial steps for the development of a serious game aimed at training users of upper limb prosthesis. In this initial phase, a virtual environment consisting of a soccer stadium was developed using Unity game engine. The game emulated the situation of a penalty kick where the users were able to control the direction to which the ball was kicked by contracting the muscles of the forearm. Experiments were performed on able-body subjects to assess their performance executing three series of ten penalties each. A score scale was implemented and the time needed to kick the penalties was measured. The results showed an intuitive and easy to play game, which was determined by the highly satisfactory performance of the subjects controlling the different functions of the game.

The myoelectric control of upper limb prostheses from surface EMG signals is characterized by the ease of data collection and by being non-invasive. Multiple functions of a prosthesis can be activated from the signals generated by a voluntary muscle contraction. In this work, we present a system that activates four functions of a hand prosthesis with two EMG channels by means of a command strategy based on the maximum voluntary contraction (MVC). Experiments were performed on five healthy subjects and one amputee to evaluate the feasibility of this strategy. The results showed a fluid and intuitive strategy, justified by an accurate performance of the subjects controlling the prosthetic functions.
