摘要： A method of gas detection includes receiving, by a data collection device, reports of detected concentrations of a particular gas from one or more gas sensing devices having one or more associated gas sensors, receiving an alarm from a gas sensing device indicating a detected concentration greater than a predetermined threshold, and receiving concentration updates from the alarming device at a rate faster than that provided by its predetermined reporting schedule. The method may further include sending a command to one or more gas sensing devices nearby the alarming device to send concentration updates. The method may further include determining a location of a gas leak by triangulating the received updates from the alarming device and the nearby devices based on their locations and/or creating and displaying a gas concentration map based on the received updates from the alarming device and the nearby devices and their locations.

摘要： A wireless spread-spectrum communication system for transmitting data includes a plurality of end point transmitters and at least one receiver. The end point transmitters transmit data via a frequency-hopped spread-spectrum FHSS signal wherein a receiver is configured for
taking a series of measurements of the power level of signals received on the predetermined channels within the predetermined frequency band;
evaluating the series of measurements over a predetermined time period;
constructing a band profile of the signal levels received on the predetermined channels;
identifying noisy channels within the predetermined channels based on the band profile; and
enabling the FHSS transmitter to adjust its transmission of signals to transmit signals avoiding identified noisy channels.
