A system and method for modifying an initial policy of an input/output device are provided. The method includes receiving, by an input/output (I/O) device, an input from a user device, wherein the input comprises an initial policy of the I/O device; collecting, by the I/O device, a first set of real-time data related to an environment in proximity of a user interacting with the I/O device; applying a machine learning model on the collected first set of real-time data to determine a current state in proximity to the user; executing a plan based on the determined current state and the initial policy received from the user device, wherein the initial policy facilitates execution of at least one plan by the I/O device; collecting, by the I/O device, a feedback data feature with respect to the executed plan, wherein the feedback data feature relates to how the user responds to the executed plan; applying a machine learning model on the collected feedback data feature to determine if the initial policy should be modified; and modifying the initial policy of the I/O device when it is determined that the initial policy should be modified based the collected feedback data feature.

A method for suppressing a non-periodic random event in a proximity system includes: receiving an output signal generated by a proximity sensor in the proximity system and monitoring at least a magnitude of the output signal; determining whether a spike having a magnitude exceeding a prescribed threshold value has occurred in the output signal; when a spike in the output signal is detected, setting an output of the proximity system to a prescribed level for a prescribed duration of time; when the prescribed duration of time has elapsed, determining whether the output signal meets one or more prescribed criteria indicative of a shutdown condition; when it is determined that the output signal meets the prescribed criteria, setting the output of the proximity system to a level exceeding an alarm threshold; and when it is determined that the output signal fails to meet at least one of the prescribed criteria, releasing suppression of the output of the proximity system.
