Abstract: A set sleep period is coordinated among a plurality of mesh network nodes to conserve power. A controller is synchronized with an existing wireless mesh network by sending a network synchronization signal from the controller indicating that sleep timing information is lost, and receiving a reply from one or more wireless mesh network nodes within the existing wireless mesh network comprising sleep timing information for the wireless mesh network.

Abstract: In an example, a method includes aligning a pin of a surface mount module with a corresponding first pin of a header pin assembly of a socket assembly of a circuit board. The first pin includes a first portion configured to electrically couple to the circuit board. A second portion includes a retention feature configured to selectively retain the second portion in engagement with the pin of the surface mount module. The surface mount module is moved in a first direction toward the circuit board, wherein the pin of the surface mount module pushes against the second portion to move the second portion to a second position to allow the pin of the surface mount module to pass by the retention feature. The second portion is configured to move back toward a first position once the pin is moved past the retention feature to engage the pin.
