Abstract: Methods, apparatuses, and systems for establishing various network configurations within a gas detection system. The method includes initializing, by a computing device associated with a gateway, a root node of a tree network, monitoring for a beacon request broadcast, wherein the beacon request broadcast is detected by the computing device from a given one of the one or more broadcasting devices, the given broadcasting device switching over from a parallel network configuration to join the tree network, determining available capability to support a connection with the broadcasting device, generating a beacon response based on the determination of available capability, transmitting the beacon response to the broadcasting device, establishing the broadcasting device as a child node device based upon a receipt of a joining request, and transmitting a join confirmation to the broadcasting device based on the establishment of the broadcasting device as a child node device.

Abstract: The gas detector calibration system comprises a control unit, a temperature regulation assembly, a pump, and a temperature sensor. The temperature regulation assembly has an inlet and an outlet, and the pump has a pump inlet and a pump outlet. The outlet of the temperature regulation assembly is coupled to the pump inlet of the pump. The temperature regulation assembly receives ambient air through the inlet, regulates a temperature of the ambient air, and supplies the ambient air to the pump through the outlet. The pump supplies the ambient air to a gas detector for regulating a temperature of the gas detector. The temperature sensor detects the temperature and sends a signal indicative of the temperature to the control unit. The control unit determines whether the temperature is within a predefined temperature range, when within the predefined temperature range, the gas detector is calibrated using a calibration gas.
