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: Radial impulse engine, pump, and compressor systems and assemblies are disclosed herein. In one embodiment, an assembly includes a first end wall portion spaced apart from a second end wall portion to at least partially define a pressure chamber therebetween. In this embodiment, the assembly also includes a plurality of movable wall portions disposed between the first and second end wall portions. Each movable wall portion includes a cylindrical surface extending at least partially between a distal end portion and a pivot axis. In this embodiment, the assembly further includes a power take out member operably coupled to the distal end portion of each of the corresponding movable wall portions.
