Abstract: A method of gas detection includes sending, by a gas sensing device to a data collection device, reports of detected concentrations of a particular gas by an associated gas sensor of the gas sensing device per a predetermined schedule or in response to an unscheduled request by the data collection device. The method may include determining whether a latest detected gas concentration is greater than a predetermined threshold, and if so, automatically sending updated reports of detected gas concentrations to the data collection device at a rate faster than that provided by the predetermined schedule. The method may further include determining whether a tracked rate that the gas concentration is changing indicates a decrease in concentration of the gas at a rate at which there is no safety concern, and if so, clearing an over-threshold alarm. A gas sensing device is also presented.

Abstract: Disclosed are techniques to conserve battery of an endpoint device. Example techniques include adjusting the size of messages transmitted by an endpoint device and/or adjusting the transmission rate of an endpoint device. In some configurations, the one or more criteria are used by an endpoint device to determine what data fields to include within a message and/or adjust a transmission rate associated with the transmission of messages by the endpoint device. For instance, the one or more criteria may include the battery level of the device, the time of year, whether the data has already been transmitted by the endpoint device, whether the data has been acknowledged as received by another device, whether the endpoint device has been instructed by another device to reduce the message size and/or adjust the transmission rate, and the like.
