Abstract: A control device may communicate messages with devices in a network through a parent device, and receive messages from auxiliary parent devices. The control device may store a respective communication metric associated with each of the parent device and the one or more auxiliary parent devices. The control device may set an auxiliary parent device of the one or more auxiliary parent devices as the parent device of the control device, e.g., when a respective communication metric of the auxiliary parent device determined to be set as the parent device indicates a stronger communication link than the parent device. The control device may determine that the respective communication metric of the auxiliary parent device indicates a stronger potential communication link than the parent device when the average received signal strength indicator of auxiliary parent device is greater than the average received signal strength indicator of the parent device.

Abstract: A control device may be configured to form a network at a unique coordinated startup time. The control device may identify a role assigned to the control device in a previously-formed network that the control device was attached to. The control device may determine a unique coordinated startup time for the control device based on the role assigned to the control device in the previously-formed network. The control device may initiate a network formation procedure at the unique coordinated startup time for the device. For example, the network formation procedure may cause the control device to attach to another control device in the network. The network formation procedure is configured to enable the control device to assume the role assigned to the control device in the previously-formed network in the new network.

Abstract: An arbitrary waveform generator including a first processor configured to output first digital data, a second processor configured to output second digital data, a first digital-to-analog converter to receive the first digital data from the first processor and output a first analog signal representing the first digital data, a second digital-to-analog converter to receive the second digital data from the second processor and output a second analog signal representing the second digital data, a system phase detector to receive the first analog signal and the second analog signal and determine a phase difference between the first analog signal and the second analog signal, and a controller configured to receive the phase difference from the system phase detector and determine a delay time for the first processor to delay an output of third digital data based on the phase difference.
