Biomedical implant with high speed, low power two-way telemetry |
摘要 |
For inbound data transmission a carrier signal is gated by the external programmer to transmit bursts of discrete numbers of cycles. The carrier is picked up by an implanted telemetry coil. The bursts are amplified and decoded by "missing pulse" detection. Outbound telemetry is synchronized with the external constant carrier in a similar manner by loading the coil for discrete numbers of cycles. In the preferred embodiment, within an eight cycle bit period, two cycles of 64 kHz carrier represent "0" while a six cycle burst represents "1", to achieve a two-way data transmission rate of 8000 bits per second.
