Efficient and fast-switching telemetry transmitter

摘要: A transmitter for a medical prosthesis which is highly efficient, and also permits rapid starting stopping so that the same coil can be used both transmission reception without undue delays between two modes of operation. During transmission, tuned circuit, consisting capacitor, pumped at frequency equal to resonant frequency. Transmission concluded when almost all energy in circuit form voltage across capacitor current through inductor approximately zero. This allows immediately reception. At start next cycle, maintained initially energize circuit.
