Patent ID: 7690569

Claim:
A data acquisition system comprising: an electronic data acquisition unit including: a housing, a first input port maintained by the housing and adapted for electrical connection to, and for receiving a first data signal generated by, a first sensor, a second input port maintained by the housing and adapted for electrical connection to and for receiving a second data signal generated by, a second sensor, a processor maintained by the housing and electronically connected to the first and second input ports such that the processor receives the first data signal and the second data signal from the first and second input ports, respectively, an aggregator module maintained by the housing and in electronic communication with the processor, the aggregator module programmed to correlate information of the first data signal as received from the first input port with information of the second data signal as received from the second input port based on time under circumstances in which a format of the first data signal differs from a format of the second data signal, including operating a filter function in which the aggregator module reduces content of the first data signal as received at the first input port, a communication device maintained by the housing and adapted to transmit information generated by the aggregator module to a location remote of the housing.
