Patent ID: 8106763

Claim:
A sensor system comprising: a first sensor powered by a line, the first sensor preprogrammed with a first time interval for transmitting data via the line; a second sensor powered by the line in parallel with the first sensor, the second sensor preprogrammed with a second time interval for transmitting data via the line; a first timing sequence control system included in the first sensor; and a second timing sequence control system included in the second sensor; wherein, in response to each instance of receiving a first power level, the first timing sequence control system is triggered and, upon being triggered, controls the transmission of the first sensor so that the first sensor transmits data via the line for the first time interval, wherein, in response to each instance of receiving the first power level, the second timing sequence control system is triggered and, upon being triggered, controls the transmission of the second sensor so that the second sensor transmits data via the line for the second time interval after the first time interval, wherein, upon being triggered, the first and second timing sequence control systems control the transmission of the first and second sensors so that the first and second sensors each transmit data via the line at least once independent of any change in a power level received by the first and second timing sequence control systems, wherein the first and second timing sequence control systems receive the first power level throughout the first and second time intervals and wherein a second power level is constantly supplied from the line to the first and second sensors, wherein the second power level is lower than the first power level, and wherein the second power level ensures that the first and second sensors are constantly in operation.
