PYRO/PIEZO SENSOR AND STIMULATOR HYBRID CIRCUIT
First Claim
1. A hybrid circuit for receiving respiration information of a patient and for providing a stimulation to the patient, the hybrid circuit comprising:
- a control input configured to receive a control signal from a closed loop neuromodulator, the control signal having a first state and a second state;
a sense switch configured to provide the respiration information from a pyro/piezoelectric film sensor and stimulator to the closed loop neuromodulator in response to the first state of the received control signal;
a stimulation switch configured to provide the stimulation energy from the closed loop neuromodulator to the pyro/piezoelectric film sensor and stimulator in response to the second state of the received control signal; and
wherein the hybrid circuit is configured to couple to the pyro/piezoelectric film sensor and stimulator using a single wire pair.

Abstract
This document discusses, among other things, an apparatus and method for receiving respiration information of a patient and for providing a stimulation to the patient using a hybrid circuit. The hybrid circuit includes a control input for receiving a control signal having a first and second state. A sense switch of the hybrid circuit can provide respiration information from a pyro/piezoelectric film sleep sensor and stimulator to a closed loop neuromodulator in response to the first state. A stimulation switch of the hybrid circuit can provide stimulation energy from the closed loop neuromodulator to the pyro/piezoelectric film sensor and stimulator in response to the second state. The hybrid circuit can couple to the pyro/piezoelectric film sensor and stimulator using a single wire pair.
