Capacitive Sensing Control and Calibration for a Child Device
First Claim
1. A child device comprising:
- a user interface comprising a capacitive sensor element configured to reflect a capacitance change in connection with an operator interaction with the user interface; and
a control circuit coupled to the capacitive sensor element to detect the capacitance change resulting from the operator interaction;
wherein the control circuit is further configured to evaluate the capacitance change to determine whether the operator interaction is initiated by a user authorized to control operation of the child device.

Abstract
A child device includes a user interface having a capacitive sensor element configured to reflect a capacitance change in connection with an operator interaction with the user interface, and a control circuit coupled to the capacitive sensor element to detect the capacitance change resulting from the operator interaction. The control circuit is further configured to evaluate the capacitance change to determine whether the operator interaction is initiated by a user authorized to control operation of the child device. In some cases, the child device may be configured to implement a learning routine involving capturing data indicative of a capacitance change, and evaluating the data to determine a threshold to be used in detection of future operator interaction.
