Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.

Implant system for controlling airway passage

A breathing assistance system having active noise control may include a gas delivery system, a patient interface, a connection system, and a noise control system. The gas delivery system may supply breathing gas to a patient via the connection system and the patient interface. The noise control system may include a processor, a speaker, a reference signal source, and a feedback sensor. The processor may generate noise control signals to be output by the speaker for canceling noise caused by a noise source of the breathing assistance system. The reference signal source may communicate reference signals associated with the noise source. The feedback sensor may detect noise caused by the noise source and noise control signals output by the speaker, and communicate to the processor feedback noise signals based on the detected noise. The processor may generate the noise control signals based at least on the reference signals and the feedback noise signals.

Systems and methods for providing active noise control in a breathing assistance system

A system for controlling a motor for use in a ventilation system may include a motor, a voltage adjustment system, a user interface, and a motor controller. The voltage adjustment system may be configured to adjust a voltage applied to the motor. The user interface may be configured to receive patient settings input from a user and communicate target ventilation parameters to the motor controller. The motor controller may include a calculation engine configured to calculate motor performance parameters for achieving the target ventilation parameters, and based at least on the calculated motor performance parameters, perform a voltage adjustment analysis for controlling the voltage adjustment system. The motor controller may further include a voltage adjuster controller configured to activate the voltage adjustment system based on a first result of the voltage adjustment analysis and to not activate the voltage adjustment system based on a second result of the voltage adjustment analysis.
