Abstract: A method, non-transitory computer readable medium, and apparatus for establishing a secure communication link between a mobile endpoint device and a networked device are disclosed. For example, the method scans an optical code, wherein the optical code contains configuration information and an encryption key, configures the mobile endpoint device in accordance with the configuration information, sends a request to the networked device to establish the secure communication link, wherein the request is encrypted using the encryption key and receives a confirmation from the networked device that the secure communication link is established between the mobile endpoint device and the networked device once the networked device has authenticated the mobile endpoint device based upon the request, wherein the confirmation is encrypted using the encryption key.

Abstract: A method and a device for canceling an offset voltage in an output of a comparator circuit include applying a signal to a first input of the comparator as a function of an initial tap point in a resistor ladder. While the signal is applied to the first input, a nominal voltage is applied to a second input of the comparator, and then an output of the comparator is analyzed. The signal to the first input is changed in response to the analyzing, by accessing a different tap point in the resistor ladder.
