The voltage feedback circuit generates the voltage control signal according to an output voltage produced using the PWM signal, a value of a reference voltage, and a value of the feedback adjustment signal.

After receiving user consent, the application groups the images on the user computing device according to object category. The user computing device captures an image of another object. The application transmits the image to the account management system, which detects objects within the image, identifies the object category, and saves the image to the corresponding object category group on the user computing device. After receiving user consent, the account management system finds information for each image in the object category group of images and transmits the information to the user computing device.
