Abstract: A medical device includes wake circuitry and telemetry circuitry. The wake circuitry is configured to receive a first set of data from a device associated with the medical device, where the first set of data is received at a frequency band. The wake circuitry is configured to output a set of pulses based on the first set of data. The wake circuitry is configured to detect a data pattern using the set of pulses. The wake circuitry is configured to output an activation signal in response to a determination that the data pattern satisfies a data pattern requirement. The telemetry circuitry is configured to output a second set of data in response to receiving the activation signal. The second set of data is transmitted at the frequency band. The telemetry circuitry is configured to establish a communication session with the device using the second set of data.

Abstract: Systems and methods for improved wireless recharging efficiency and decreased processing requirements are described. A plurality of duty cycle/input voltage pairs are stored in a recharger, corresponding to three subsets: a first subset corresponding to a constant minimum input voltage and an increasing duty cycle; a second subset corresponding to a constant duty cycle and an increasing input voltage; and a third subset corresponding to a maximum input voltage and an increasing duty cycle.
