  • INTERFERENCE DETECTION AND MITIGATION IN INDUCTIVE SENSOR APPLICATIONS AND DYNAMIC ADAPTATION BASED ON REAL-TIME NOISE DETECTION
    Publication number: 20210357062
    Abstract: A system may include a resistive-inductive-capacitive sensor, a driver configured to drive the resistive-inductive-capacitive sensor at a driving frequency, a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to measure phase information and amplitude associated with the resistive-inductive-capacitive sensor, and a noise detection circuit communicatively coupled to the measurement circuit and configured to determine a presence of external interference in the system based on at least one of the phase information and the amplitude information.

  • BASELINE CALCULATION FOR SENSOR SYSTEM
    Publication number: 20210152174
    Abstract: A method may include receiving an input signal, generating a baseline signal based on the input signal, generating a corrected input signal by subtracting the baseline signal from the input signal, determining a threshold level change of the input signal when the corrected input signal exceeds a level change threshold, and responsive to the threshold level change, updating the baseline signal to the level change threshold.

  • Active charge through of a peripheral device
    Patent number: 10579119
    Abstract: A method for port policy management for active charge through of a peripheral device that has a first communication port and a second communication port may include detecting whether a valid power connection exists at the peripheral device, in response to detecting the valid power connection, determining a relationship between the first communication port and the second communication port, based on the relationship, determining, by the peripheral device, a power relationship among the peripheral device, the first communication port, and the second communication port, selectively configuring the first communication port, the second communication port, and the peripheral device to match the power relationship, and enabling active charging through of the peripheral device if active charging through is supported by the power relationship.

  • DETECTING AND ADAPTING TO CHANGES IN A RESONANT PHASE SENSING SYSTEM HAVING A RESISTIVE-INDUCTIVE-CAPACITIVE SENSOR
    Publication number: 20200064160
    Abstract: A system may include a resistive-inductive-capacitive sensor, a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor, and a filter communicatively coupled to the measurement circuit. The measurement circuit may be configured to measure phase information associated with the resistive-inductive-capacitive sensor and based on the phase information, determine a displacement of a mechanical member relative to the resistive-inductive-capacitive sensor. The filter may be configured to isolate changes to the displacement which are significantly slower than an expected change to the displacement in response to a human interaction with the mechanical member.
