Abstract: Various embodiments include methods for rotating a control node role among devices in a control cluster of a wireless mesh network. Methods may include assuming the control node role by a first device based on a control node assumption timing in a schedule, and transmitting periodic messages to support the wireless mesh network. Methods may further include using the schedule to identify a control node role end timing and a third device in the control cluster that will assume the control node role, transmitting the periodic messages while monitoring for an extended advertisement from the third device after the control node role end timing until the extended advertisement from the third device is received, and assuming a passive node role upon receiving the extended advertisement from the third device or continuing the control node role when no extended advertisement is received from the third device.

Abstract: A system and method for logging a non-reader into a corresponding user account is disclosed. A system can include a processor, a user interface, a display, and a camera. The processor can be programmed to display a first plurality of pictures and configure the user interface to allow the user to select a first picture corresponding to the user from the first plurality of pictures to provide a first authentication step and allow the user to select a second picture from a second plurality of pictures providing a second authentication step. The system can log the user into the corresponding user account if the second picture selected from the second authentication step corresponds to the first picture selected from the first authentication step. A system and method for logging multiple users into corresponding user accounts is also disclosed.
