摘要： An adaptive, performance-optimizing communication system for communicating with an implanted medical device in which signals are transmitted and received in accordance with predetermined, interrelated operational parameters, such as transmission rate, transmitter power, and the like. Various aspects of system performance, including bit error rate in received signals, the strength of received signals, the signal-to-noise ratio of received signals, the presence of local RF noise and non-telemetry related RF signals, and the like, are dynamically monitored by the communication system, to determine whether predetermined system performance goals are being met. If it is determined that one or more system performance goals are not being met, one or more operational parameters may be automatically adjusted so that desired performance can be achieved.

摘要： A power supply arrangement for a battery-powered device includes a high energy density capacitor which is selectively coupled to the device's battery. In one embodiment, the device includes a first circuit which requires a continuous operational power supply voltage to be applied to its power supply input, and further includes a second circuit periodically operates in a peak phase in which it places a high demand upon the device's battery. During normal operation of the device, the first circuit's power supply input and the high energy density capacitor are coupled to the battery so that operational power for the first circuit is provided directly from the battery, and the high energy density capacitor is charged by said battery. During the peak operational phases of the second circuit, the first circuit and high energy density capacitor are decoupled from the battery, such that operational power for the first circuit is provided from the capacitor, while operational power for the second circuit is provided from the battery. During the peak phases, the output voltage of the high-energy density capacitor is monitored, and if it falls below predetermined minimum threshold level, the first circuit's power supply input terminal and the capacitor are temporarily re-coupled to the battery, so that sufficient operational power to the first circuit is ensured.
