TOUCH-SENSOR ACCURACY IN NOISY ENVIRONMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240211076 titled 'TOUCH-SENSOR ACCURACY IN NOISY ENVIRONMENTS
The abstract describes a capacitive touch-sensor system that includes an electrode array connected to an electromagnetic-noise source, a hardware interface, and output logic. The system detects touchpoints by analyzing sensory signals from the electrode array and filtering out noise from the electromagnetic-noise source.
- Electrode array acquires sensory signal
- Hardware interface provides touch-position output
- Output logic identifies anomalous sensory electrodes near touchpoints
- Non-anomalous sensory electrodes are used to detect noise
- Sensory signal exceeding a threshold is invalidated for touchpoint resolution
- Touch-position output is computed based on the sensory signal
Potential Applications: - Touchscreen devices - Human-machine interfaces - Interactive displays
Problems Solved: - Filtering out noise from touch sensors - Improving touchpoint accuracy
Benefits: - Enhanced touch sensitivity - Improved touchpoint resolution - Reduced interference from electromagnetic noise
Commercial Applications: - Consumer electronics - Automotive touchscreens - Industrial control panels
Questions about Capacitive Touch-Sensor System: 1. How does the system differentiate between anomalous and non-anomalous sensory electrodes?
The system identifies anomalous electrodes by their anomalous response to noise from the electromagnetic-noise source.
2. What are the advantages of using capacitive touch sensors over other types of touch sensors?
Capacitive touch sensors offer higher sensitivity, durability, and multi-touch capabilities compared to other touch sensor technologies.
Original Abstract Submitted
a capacitive touch-sensor system comprises an electrode array coupled to an electromagnetic-noise source, a hardware interface, and associated output logic. the electrode array acquires sensory signal. the hardware interface exposes a touch-position output of the capacitive touch sensor. the output logic determines that an anomalous sensory electrode of the electrode array is proximate to a touchpoint, the anomalous sensory electrode providing an anomalous response to noise from the electromagnetic-noise source. pursuant to determining that the anomalous sensory electrode is proximate to the touchpoint, the output logic identifies a non-anomalous sensory electrode of the electrode array which is usable to detect the noise. if an amplitude of the sensory signal from the non-anomalous sensory electrode exceeds a predetermined threshold, then the output logic invalidates the sensory signal for touchpoint resolution. if the sensory signal is not invalidated, the output logic computes the touch-position output based in part on the sensory signal.
