Described here are stimulation systems and methods for stimulating one or more anatomical targets in a patient for treatment conditions such as dry eye. The stimulation system may include a controller and a microstimulator. The components of the controller and microstimulator may be implemented in a single unit or in separate devices. When implemented separately, the controller and microstimulator may communicate wirelessly or via a wired connection. The microstimulator may generate pulses from a signal received from the controller and apply the signal via one or more electrodes to an anatomical target. In some variations, the microstimulator may include a passive generation circuit configured to generate a pulse based on a signal received from the controller.

Stimulation devices and methods

A mechanism for retrieval of carrier frequency and carrier phase in a received modulated carrier waveform. Retrieval of carrier frequency and carrier phase can be implemented in an analog electrical circuit, using a field programmable gate array (FPGA), or in computer code. Independent of the implementation, the mechanism performs frequency and primary phase recovery by forcing transforms of a pilot tone in the upper and lower sidebands to the same frequency using a feedback loop. The difference-in-magnitudes of the channelized pilot are used by a phase lock loop to perform secondary phase recovery in a manner that also resolves phase sign ambiguity. Benefits of this mechanism include improved phase lock loop tracking performance and a reduction of noise in the data demodulated from the received carrier waveform.
