Abstract: A current control module is employed to protect a conductive feature of a printed circuit board (PCB) from an overcurrent event by comparing a reference voltage output from a compensation circuit connected to a reference power supply to a voltage output from a conductive feature connected to a power supply which is different from the reference power supply. The reference output voltage is representative of an anticipated voltage output from the conductive feature. The current control module is configured to initiate regulation of power to the conductive feature when the voltage output from the conductive feature exceeds the reference voltage output.

Abstract: Business goals may be achieved using adaptive rewarding for the personalization of contents. In response to receiving user information, personalized contents for the user can be recommended using a reinforcement learning algorithm. In response to presenting the personalized content to the user, an action by the user selecting a particular content may be received. A reward value can be calculated for the action based on a reward function. The reward function can be based, at least in part, upon the action, the selected content, and/or the user. The reward function can be based upon one or more business goals, such as user engagement, monetization, and/or security. The calculated reward value can be provided to the reinforcement learning algorithm, which can be adapted based upon the reward value for future selection of personalized contents.
