A therapeutic applicator uses a frangible wall to mix reactive fluids in internal chambers for targeted temperature control.
- Microphone-Based Touch Gesture Detection in Headsets
Acoustic signal processing distinguishes intentional touch gestures from ambient noise, eliminating false identifications without adding hardware sensors.
- Active Vibration Cancellation in Computer Systems
A vibration cancellation system monitors mechanical disturbances and analyzes harmonics using accelerometers to identify specific frequency components.
- Facial Skin Indentation Preventer with Cannula Pocket
Layered flaps and hinges create a cushioned cannula pocket that distributes pressure across the skin.
- Room Communication System Stabilizing Feedback via Time Delay
A room communication system stabilizes electro-acoustic feedback loops by applying precise time delays to electrical signals before acoustic conversion.
- Voice Activity Detector Sub-Frame Energy Analysis
Sub-frame energy analysis reduces stabilization time below 250 milliseconds, eliminating false alarms caused by strong noise transitions.
- Fan Noise Cancellation via Virtual Error Signal
Active noise cancellation controller generates anti-noise signals using a virtual error microphone to suppress fan-generated broadband acoustic disturbances.

A biodegradable valve device secures to the stomach wall using an adhesive flange to allow unidirectional swallowing flow.
- Catheter Removal Device with Rotating Cutting Head
A fluid line removal device uses a rotating serrated cutting head to separate the catheter from surrounding tissue.
- Non-Invasive Ear Correction Apparatus for Newborns
A non-surgical ear correction apparatus reshapes newborn ears using adjustable support lines and correction balls.
- Adaptive Noise Cancellation via Off-Ear Position Detection
An adaptive noise cancellation system uses error microphone feedback to detect off-ear positions, reducing wasted energy when the audio device is not worn.
- Adaptive Notch Filter for Active Vibratory Noise Control
Adaptive notch filters update coefficients via sine and cosine corrective values to generate precise reference signals.
- Tongue-Type Guide Vane for Ear Canal Airflow Control
An asymmetric guide vane creates a vortex field that sweeps moisture from the external auditory canal without risking eardrum injury.
