Apparatus and method for wireless gas monitoring
First Claim
1. An apparatus for use in monitoring for a selected gas from a potential source of the selected gas, said apparatus comprising a housing, control apparatus disposed within said housing, data entry apparatus mounted on said housing and connected with said control apparatus, said data entry apparatus being operable to enter data which is transmitted from said data entry apparatus to said control apparatus, a display mounted on said housing and connected with said control apparatus, said display being operable to display indicia which is a function of data entered at said data entry apparatus, a sensor connected with said control apparatus, said sensor being operable to sense atmosphere adjacent to said housing and to provide an output which is conducted to said control apparatus, said output from said sensor is a function of a sensed concentration of the selected gas in the atmosphere adjacent to said housing, and a radio disposed in said housing and connected with said control apparatus, said radio being operable to transmit data to a data receiving station which is spaced from said housing, said data transmitted by said radio to said data receiving station is a function of a concentration of the selected gas sensed by said sensor.

Abstract
The current invention discloses a wireless monitoring system. The system has one or more monitoring devices. Each device can transmit data and receive messages from an output center or alarm system. The output center can also transmit and receive messages. Both the output center and each device preferably have a transceiver that enables both the transmission and receipt of messages. No remote terminal units or hardwiring is required for the system to function. The system is truly a wireless gas monitoring system. The system may use low earth orbit satellite technology, or licensed radio frequencies or any other means to wirelessly transmit and receive messages.

- 1. An apparatus for use in monitoring for a selected gas from a potential source of the selected gas, said apparatus comprising a housing, control apparatus disposed within said housing, data entry apparatus mounted on said housing and connected with said control apparatus, said data entry apparatus being operable to enter data which is transmitted from said data entry apparatus to said control apparatus, a display mounted on said housing and connected with said control apparatus, said display being operable to display indicia which is a function of data entered at said data entry apparatus, a sensor connected with said control apparatus, said sensor being operable to sense atmosphere adjacent to said housing and to provide an output which is conducted to said control apparatus, said output from said sensor is a function of a sensed concentration of the selected gas in the atmosphere adjacent to said housing, and a radio disposed in said housing and connected with said control apparatus, said radio being operable to transmit data to a data receiving station which is spaced from said housing, said data transmitted by said radio to said data receiving station is a function of a concentration of the selected gas sensed by said sensor.
- 19. An apparatus for use in monitoring for a selected gas from a potential source of the selected gas, said apparatus comprising a housing, a sensor operable to provide an output which is a function of a senses concentration of the selected gas in the atmosphere adjacent to said housing, a radio operable to transmit data to a data receiving station which is spaced from said housing, and control apparatus disposed in said housing and connected with said sensor and said radio, said control apparatus be operable to determine when a moving average of concentration of the selected gas sensed by said sensor over a predetermined period of time exceeds a predetermined magnitude and to effect transmission of a signal from said radio to said data receiving station when the moving average concentration of the selected gas sensed by said sensor over the predetermined length of time exceeds the predetermined magnitude.
- 31. An apparatus for use in monitoring for a selected gas from a potential source of the selected gas, said apparatus comprising a housing having front and rear sides, a sensor operable to provide an output which is a function of a sensed concentration of the selected gas in the atmosphere adjacent to said housing, a radio disposed in said housing, said radio being operable to transmit data to a data receiving station spaced from said housing, control apparatus disposed in said housing and connected with said sensor and with said radio, said control apparatus being operable to effect transmission by said radio to the data receiving station of data which is a function of concentration of the selected gas sensed by said sensor, a plurality of manually actuatable switches connected with said control apparatus and disposed adjacent to said front side of said housing, indicia disposed in association with said switches to enable an individual to selectively actuate said switches and enter data relating to the selected gas into said control apparatus, and a display connected with said control apparatus and disposed adjacent to said front side of said housing to provide information to the individual actuating said switches.
- 48. An apparatus for use in monitoring for a selected gas from a potential source of the selected gas, said apparatus comprising a sensor which is operable to provide an output which is a function of a sensed concentration of the selected gas in the atmosphere adjacent to said sensor, a radio operable to transmit data to a data receiving station, and control apparatus connected with said sensor and with said radio, said control apparatus being operable to eliminate the effect of transient variations in the concentration of the selected gas in the atmosphere adjacent to said sensor by averaging the magnitude of the concentration of the selected gas sensed by said sensor over a predetermined length of time, said control apparatus being operable to effect transmission by said radio to the data receiving location of data which is a function of the average magnitude of the concentration of the selected gas sensed by said sensor over the predetermined length of time.
