Abstract

Inventia se refera la un dispozitiv de comanda prin biopotentiale pentru proteze vocale. Dispozitivul de comanda pentru proteze vocale, conform inventiei, este alcatuit dintr-un electrod diferenta, care se pozitioneaza, de preferinta, pe lobul urechii sau pe mîna si unul sau mai multi electrozi activi, pozitionati în punctele de potential maxim pe pielea sau imediat sub pielea gîtului sau a fetei, un grup de amplificatoare ce amplifica potentialele culese, un grup de tip vocoder pentru fiecare canal care cuprinde bancuri de filtre conectate în paralel, circuite redresoare si circuite de integrare, un circuit de prelucrare, decizie si decodificare, precum si circuite de comanda (adresare). Dispozitivul de comanda pentru proteze vocale, în scopul folosirii unui singur amplificator si al eliminarii dispozitivului de tip vocador, foloseste un multiplexor analogic comandat de un circuit de comanda, precum si o memorie.The invention relates to a biopotentials command device for vocal prostheses. The vocal prosthesis control device according to the invention consists of a difference electrode which is preferably positioned on the earlobe or on the hand and one or more active electrodes positioned at the maximum potential points on the skin or immediately below the neck or face skin, a group of amplifiers that amplify the picked potentials, a vocoder group for each channel that includes parallel junction filters, rectifier circuits and integration circuits, a processing, decoding and decoding circuit, and command circuits (addressing). The vocal prosthesis control device, for the purpose of using a single amplifier and removing the vocador device, uses an analog multiplexer commanded by a command circuit as well as a memory.
