Abstract: System and method for transmitting data over a wireless medium. A wireless sensor node receives data from at least one sensor, where the data include a plurality of data sets. For each data set: the wireless sensor node compares the size of the data set with a specified packet size, and if the size of the data set exceeds the specified packet size, transmits a plurality of packets containing respective portions of the data set to a gateway device over a wireless medium. If the size of the data set does not exceed the specified packet size, then a packet containing the data set is transmitted to the gateway device over the wireless medium.

Abstract: A measurement device operable to communicate with a computer system via files. The computer system may receive one or more files created by the measurement device, where the files include measurement data generated by the measurement device and may utilize the files to perform a measurement application. The measurement device may also be operable to receive a configuration file from the computer system and configure or control itself according to commands or settings therein. In one embodiment the measurement device may appear to the computer system as a USB Mass Storage device, and the files created by the measurement device may appear as files stored on a USB Mass Storage device. Thus, the computer system may communicate with the measurement device to obtain the measurement data files in the same standard manner in which it would obtain files stored on any other USB Mass Storage device.
