Core Innovation
The invention provides a high flow nasal cannula (HFNC) system comprising a controller, at least one first sensor, a compensating device, a first housing disposed with the at least one first sensor, and a second housing disposed with the compensating device. The controller is communicatively connected with the at least one first sensor and the compensating device respectively. The at least one first sensor collects first sensing data and sends the first sensing data to the controller.
The controller receives the first sensing data, generates a first driving signal according to the first sensing data, and sends the first driving signal to the compensating device. The compensating device receives the first driving signal and causes vibration of the compensating device according to the first driving signal. Vibration of the second housing caused by vibration of the first housing is compensated by the vibration of the compensating device.
In additional embodiments, the compensating device comprises an actuator and at least one second sensor, and the actuator and the at least one second sensor are communicatively connected to the controller respectively. The at least one second sensor is used to collect second sensing data, and the controller can determine whether the vibrational amplitude of the second housing is below a first threshold value based on second sensing data including vibrational amplitude and vibrational phase.
The controller can adjust the first driving signal based on amplitude scaling factor and phase shifting factor, optionally using an averaging operation across second sensors, and can implement multi-surface compensation using multiple compensating devices and sensors.
Claims Coverage
The claim set covers one independent claim with six inventive features centered on an HFNC vibration-compensation architecture and related sensing and control refinements.
Controller-driven vibration compensation between first and second housings
An HFNC system where a controller receives first sensing data collected by at least one first sensor disposed in a first housing, generates a first driving signal according to the first sensing data, and sends the first driving signal to a compensating device in a second housing so that vibration of the second housing caused by vibration of the first housing is compensated by vibration of the compensating device.
Actuator and second sensor in the compensating device
The compensating device comprises an actuator and at least one second sensor, where the actuator and the at least one second sensor are communicatively connected to the controller respectively.
Secondary sensing of vibrational amplitude and vibrational phase with threshold-based control adjustment
The controller uses second sensing data collected by the compensating device including vibrational amplitude and vibrational phase to determine whether the vibrational amplitude of the second housing is below a first threshold value, and adjusts the first driving signal according to the vibrational amplitude and the vibrational phase using an amplitude scaling factor and a phase shifting factor.
Averaging across multiple second sensors before thresholding
The controller averages second sensing data from multiple second sensors to obtain averaged second sensing data and determines whether the vibrational amplitude of a second housing is below a first threshold value based on the averaged second sensing data.
Multi-sensor configurations for the second sensor
The at least one second sensor comprises multiple second sensors that are randomly placed on a surface of a second housing or arranged on the surface of the second housing in an array.
Housing relationship constraints between the first housing and second housing
The first housing is located within the second housing.
Overall, the claims cover an HFNC system architecture in which a controller uses sensing from a first housing to drive a compensating device that vibrates to compensate vibration of a second housing, with further refinements using actuator/second-sensor feedback, vibrational amplitude and phase sensing with threshold-based adjustment, averaging across multiple sensors, configurable sensor layouts, and first/second housing arrangement.
Stated Advantages
Reduces vibration of the second housing by compensating vibration of the second housing caused by vibration of the first housing.
Documented Applications
Noise reduction workflow for HFNC systems, including an optional sound/noise mitigation subsystem where a sound-producing device on a first housing and earplugs perform noise-reducing processing on sound related to a gas delivering device.
